Air conditioning at home how to make. Tricks with a cardboard box

Not all people calmly endure the summer heat, being indoors. For many, it negatively affects performance, reduces appetite and worsens well-being. The solution to the problem is the installation of an air conditioner or a split system, but for various reasons this option is not available to everyone. Therefore, savvy home craftsmen came up with several ways to make an air conditioner on their own with minimal financial costs and with the help of improvised means. Those who suffer greatly from the heat are invited to consider these methods, choose the right one and make a cooler with their own hands.

How does a conventional air conditioner work?

To identify strengths and weak sides homemade coolers, for starters, it does not hurt to understand the structure of traditional split systems and understand how they work. Such a climate control system consists of several parts and assemblies:

• an external and internal radiator, called a heat exchanger;
• radiators are interconnected by copper tubes, where gaseous substance- freon (technical name - refrigerant);
• a compressor is installed on one line, creating overpressure and causing freon to move through the tubes and condense;
• a special expansion valve is embedded in the second line.

Important. Operating principle refrigeration machine, which is the air conditioner, is based on the ability of freon to evaporate when low temperatures, due to which thermal energy moved from indoors to outdoors.

The refrigerant is constantly moving in a closed circuit, evaporating in one heat exchanger and condensing in another. The heat transfer algorithm looks like this:

1. Freon enters the internal radiator (it is also the internal module of the split system) in liquid form. Flow room air blown by the fan passes through the fins of the heat exchanger, causing the refrigerant to heat up and evaporate. At this moment there is an intensive selection of heat from the air environment of the room.
2. Further, gaseous freon enters the compressor, which increases its pressure. The goal is to compress the substance to such an extent that it condenses in an outdoor radiator, where the temperature is even higher than in the room.
3. Getting into the external heat exchanger, blown by its fan, the refrigerant passes into liquid state and moves along the tube back into the room. At the moment of transition, it gives off the heat taken from the room to the street air.
4. On the way back, liquid freon passes through an expansion valve that reduces pressure so that it can evaporate in the internal radiator. Then the cycle repeats.

Note. All processes occurring in the split system are controlled by an electronic unit using various sensors.

As you can see, the device of the factory air conditioner and the principle of operation is quite complicated. It can be implemented at home by a technically competent specialist in this field, but not by an ordinary user. Yes, you will have to spend money on parts. Homemade designs cooling devices are much simpler and cheaper to manufacture.

Options for homemade air conditioners

From improvised means and materials, home craftsmen make the following types of air coolers:

• devices operating on cold water;
• devices that extract cold from ice;
• homemade air conditioners from portable or old household refrigerators.

In the first two versions, the source of cold is water and ice blown by a simple axial fan from someone household appliance(eg computer). The third method allows you to assemble a device that is similar in principle to a full-fledged air conditioner, but with certain limitations. How these options are implemented technically is worth considering in more detail.

Assembling a cooler from a car radiator

Units of this type operate according to the old principle proven in practice and are identical in design to industrial heaters, otherwise - water fan heaters. The bottom line is that water of the required temperature is passed through a radiator, which is blown from the outside by a fan. The air passing through the fins of the heat exchanger is cooled by 5-15 °C, depending on the temperature of the flowing water.

An important point. Heaters have one valuable advantage: they are able to function in summer for cooling, and in winter - for heating the air flow. To change the mode, just send it to the radiator hot water from the heating system instead of the cold one.

To make an impromptu winter-summer air conditioner at home, you will need:

• car cooling system radiator in good condition;
• outdoor household fan with a large impeller;
• a plastic or metal tray with low sides, equal in length to the size of the radiator;
• a case where you can embed the listed elements (for example, from an old TV);
• connecting hoses and adapters;
• clamps and fasteners.

Advice. If you want to receive more comfort when operating the air conditioner, then take a fan with a remote control.

You can make the body for the cooler and the tray yourself from the materials available in household. The purpose of the latter is to collect condensate that forms on the radiator fins from the temperature difference between the flow and circulating water. Assembly is done in this order:

1. Check the car radiator for leaks, if necessary, solder the leaks or close them with cold welding. Then install its body and attach it with steel corners and self-tapping screws (bolts).
2. Attach a tray underneath the radiator. If the sides come out too low and the tank begins to quickly fill with condensate, then attach a tube to it to drain water into the sewer.
3. Behind the heat exchanger, install the fan impeller, separating it from the rack with control buttons.
4. Attach hoses to the radiator pipes for supplying and discharging water. This completes the assembly.

To start a homemade air conditioner, connect the fan to the mains, and the hoses to a source of cold water. This can be a domestic water supply or a pump that raises water from a well or well. The last 2 options are preferable, since the temperature of underground aquifers is just acceptable - 8-14 ° C. Send the return line to the sewer, a large collection barrel, or use it to water the garden.

Reference. It is highly undesirable to water the plants with cold water from a well in the summer. By passing it through the radiator, you will kill two birds with one stone: cool the room and heat the water for the garden.

Compact air conditioner from a plastic bottle

For this homemade device to work, you will need ice, and you can’t do without a working refrigerator or freezer. But the cooler will come out compact and quite efficient for a small room, for example, in an apartment. The principle is simple: ice is placed in a container, and a fan blows air through it, due to which the latter is well cooled. To assemble the air conditioner you will need:

• a large plastic bottle with a capacity of 5, and preferably 9 liters;
• domestic duct fan which are used for hoods in the bathroom;
• thin clothesline;
• plastic folder;
• knife and drill with a drill 8-10 mm.

Advice. The requirements for the fan are simple - it must be cheap and small in size. If desired, you can also adapt a cooler from a computer, but then the performance of the cooler will decrease significantly.

Making an air conditioner takes no more than an hour and is carried out in several stages:

1. Cut the neck of the bottle with a knife so that the fan housing fits into the opening as tightly as possible.
2. At a height of 7-10 cm from the bottom of the bottle, drill the wall in a circle. The distance between the holes is no more than 5 cm.
3. Passing a clothesline through the holes, make a grid that overlaps the section of the container.
4. Cut out a circle from a plastic folder, whose diameter is equal to the size of the bottle. Drill holes in it, and then lay it inside the container on a rope net.

To start the cooler, you need to put on the second bottom, made of a plastic folder, more ice, insert a fan into the cut-out neck and turn it on. The air forced inward will pass through the ice, cool down and exit through the side openings.

Advice. To ensure that ice lasts for a long time, freeze it not in a special mold, but in plastic cups. You will get large chunks that take longer to melt. Another option is to use commercially available cold storage batteries instead of ice.

In the same way, a cooling device is made from a portable refrigerator. Its insulated body is used instead plastic bottle, and cold accumulators or frozen water in small containers are placed inside.

Air conditioning from an old refrigerator

Since the air conditioner and refrigerator operate on the same principle, the latter can be used to cool the room. The main thing is that the compressor and heat exchangers of the old refrigerator remain in working order, otherwise you will have to spend money on repairs and pumping freon. What else is required:

• household fan;
• 2 coolers from the computer;
• fastener elements;
• locksmith tool for disassembling an old refrigerator.

Note. Collect similar design it will turn out only in a private house, this option is not available for residents of apartments. Later you will understand why.

When manufacturing, you can go in two ways: remove the heat exchangers, compressor and tubes, or leave them in the old building. The task is to bring an external black radiator to the street along with a compressor. If there is an opening in the wall of sufficient size, then the entire refrigerator can be built into it without removing the insides. When the wall opening is small, only the internal heat exchanger will pass through it. To remove it without violating the tightness of the tubes, the refrigerator case must be carefully cut. Then proceed like this:

1. Attach the black outdoor radiator to the wall outdoors, and the indoor one indoors. To make the latter look decent, make a decorative case for it.
2. impeller household fan fasten so that it blows over the compressor and the external radiator.
3. Place the coolers inside the heat exchanger, which used to serve as a freezer.

The air conditioner from an old refrigerator will never turn off until you do it yourself. The reason is that the automation is set to turn off the compressor at a temperature indoor module minus 5 ° C, and this is impossible in the middle of summer. The second nuance: the unit is not designed to cool large volumes of air, so it makes no sense to install it in large rooms, there will be no sense from it.

Important. Before connecting to the power supply, be sure to provide grounding of the device so that in the event of a breakdown and short circuit none of your loved ones were electrocuted.

Simplified designs for the home

One such design is a water heat exchanger combined with a conventional floor fan. To make such a primitive cooler, you need to take a copper tube and roll it into a spiral, attaching it to the fan's protective grille. For installation, you can use plastic clamps used for fastening wiring in cars. The ends of the tube are connected to the water supply, and the fan is connected to the network.

Note. The described design is inefficient, because tap water not cold enough, and the usable area of ​​the copper heat exchanger is too small. The air flow from the impeller will cool slightly and nothing more.

The original design was invented in one of the African countries, where it is traditionally hot and, in addition, there is no electricity supply. The device works on the basis of the law of physics, which states that the temperature of a gas passing through a sudden contraction and expansion drops by several degrees (up to 5 ° C). The neck of the same plastic bottle acts as such a narrowing, and in order to get more chilled air, you need to use a dozen of these necks.

A non-volatile air conditioner is done like this:

1. Cut a piece of plywood or fiberboard the size of the opening window hole. Check how many bottles you can put on it close to each other.
2. Cut off the necks on all bottles and twist the corks. Then place them on a sheet of plywood and mark the centers of the holes with a pencil.
3. Make holes with a core drill whose diameter matches the neck. Insert cut bottles into them.
4. Attach plywood to the outside of the window opening so that the bottles stick out to the street.

The device is suitable for country house, where other options cannot be applied due to the lack of the right amount water or power outages.

Pros and cons of homemade coolers

The undoubted advantage of improvised home-made air conditioners is their cheapness. As a rule, most of the components needed for assembly can be found in your own pantry or garage. The rest of the parts are purchased in the distribution network for relatively little money.

When assembling any of the proposed types of coolers with your own hands, you need to understand that you will have to put up with the numerous disadvantages of such units:

1. Models using running water, work inefficiently when connected to cold water pipes. The reason is that the supply water temperature is too high. In addition, the air conditioner "winds" cubic meters on the meter, and you have to pay for it.
2. When using well and borehole versions of water installations, the question arises of where to put the water pumped through the radiator.
3. Ice devices cool the rooms well, but at the same time humidify the air. With a glut of moisture, the heat in the room turns into stuffiness after the device is turned off.
4. Ice needs to be frozen in the refrigerator, that is, you need to spend electricity and pay for it. The second nuance: while you are cooling one room with a home-made air conditioner, in the next room the refrigerator catches up with the heat released when the water freezes.
5. Cooling with a freon circuit from an old refrigerator is ineffective, because the system is not designed to operate in this mode. Again, a continuously operating compressor "winds" the electricity meter.

Note. The only model whose manufacturing and operating costs correspond to the effect obtained is an air conditioner made from bottles inserted into a plywood sheet. It reduces the temperature in the room by a maximum of 5 °C, partly by blocking the light opening.

In the article we will talk about how to make an air conditioner with your own hands for your home or car. It is worth noting that home-made appliances can be an alternative to any modern split systems. With the help of appliances that create a comfortable microclimate in the house, you can save a lot of money. Split systems have high cost their installation is rather complicated.

And so many home and car owners come up with a variety of installations that can cool the air in the room. In the article we will consider all design options that are most suitable for use. They can be used in both homes and cars. In order to understand how difficult the task of making a homemade air conditioner is, you need to consider the principle of its operation. And you will also have to identify the advantages and disadvantages of designs that are available for repetition.

Is it easy to make an air conditioner

And now let's decide whether it is easy to make a home air conditioner yourself. In order to maintain the temperature in the room at a certain level, it is necessary to carefully regulate the pressure of the refrigerant in the split system. For this, an electronic control unit is installed, which receives signals from various sensors. It should be noted that the same scheme works and car air conditioner. In it, the evaporator is installed in the interior heating system, and the condenser is mounted near the radiator, which is necessary for normal operation engine cooling.

As you understand, make homemade air conditioner such a design at home is quite difficult. As for the installation in cars, it is even more difficult to do. Of course, if you have experience with refrigeration equipment, all manipulations can be carried out quite quickly and independently install the air conditioner in a car or house. There are many designs that anyone can repeat with minimal skills and using standard tools.

The design of a simple air conditioner

This is a very simple design in which a cold source must be installed inside a closed box. Consider how to make an air conditioner at home. An axial fan must be installed in one side wall of the box. With reverse side, opposite the fan, it is necessary to make a hole through which the cooled air will exit. And now about what you can make this type of air conditioner from:

• Old car refrigerators with walls insulated with foam or foam plastic.
• Boxes made of plastic or cardboard.
• plastic cans.
• Bottles of 5 liters or more.

To supply air inside the box, you can use any small-sized fans. Coolers that are used in computer technology are ideal.

Such a small air conditioner can be useful for cooling the car interior. It is only necessary to connect the cooler correctly so that the blades rotate in the right direction. It is also recommended to use special ice generators that are able to give coolness for a long time.

Design pros and cons

This design has both disadvantages and advantages. First, among the advantages, one can single out the fact that the design is very simple. Secondly, it can be made from any materials, so the cost will be extremely low. Thirdly, such an air conditioner can really cool a small space. But there are also disadvantages that outweigh all the advantages:

1. At very high temperature no amount of ice is enough for the normal operation of such an air conditioner. If you plan to cool one room, the one where the ice is made will be warmed up due to the operation of the refrigerators. Consequently, the consumption will increase electrical energy.
2. If you are using the unit in a car, the operating time will depend on how much ice you have brought with you.
3. The disadvantage is that the air will be humidified as it passes through the ice. In other words, after a certain period of time, the air in the room will be oversaturated with moisture, which will make it much worse than heat.

Of course, if you use cold accumulators, then the air will not be humidified.

Construction assembly

And now let's look at how to make a homemade air conditioner for your home or car. In order to make a design, you will need to perform simple manipulations:

1. Find a container that closes as tightly as possible. In one wall on the side, it is necessary to cut a hole that will correspond to the diameter of the fan.
2. Then you need to screw the cooler with self-tapping screws to the case.
3. Now make another hole, it should be located opposite the first one. It is recommended to use a small piece of pipe for greater convenience.
4. Many users of such devices claim that it is most convenient to use sealed boxes, the lid of which can be easily removed. Ideal food containers. It is very convenient to load ice or cold accumulators into them.
5. And now you need to install the air conditioner and connect it to the power source. As for the use in cars, you need to install it in a convenient place, and connect the cooler to the cigarette lighter.

Liquid installation

This design is efficient and easy to manufacture. A heat exchanger and a fan are installed in the room. Cold water passes through this heat exchanger, the fan blows it, the temperature in the room decreases. A well or well can be used as a source of water. As for the heat exchanger, a radiator from any car or an air conditioner that has become unusable is ideal. It is worth noting that this design can not only cool the air in the room, but also heat it. To do this, just supply hot water to the radiator.

It consists of three components:

1. Submersible or well pump.
2. Heat exchanger with fan.
3. Insulated pipelines for the supply and discharge of liquid.

How to make a liquid type air conditioner

And now let's look at how to assemble the system yourself. To do this, you need to perform the following manipulations:

1. Place a radiator from the car in a convenient place in the room and install a fan.
2. Mount the return and falling lines. In order to connect them to the nozzles, it is necessary to use adapters and clamps.
3. Install a pump in a well or well, connect pipes to it, through which water will be supplied to the radiator.
4. It is recommended that the section of the pipe through which cold water is supplied be wrapped insulation material. This will allow the liquid not to heat up ahead of time. As for the return line, it does not need to be isolated.

Where to put water?

Immediately decide where you will put the water after it passes through the radiator. It should also be noted that very often the fluid flow rate is much higher than necessary.

As for the problem of fluid discharge, it can be solved in the following ways:

1. Collect liquid in any storage capacity(if you water household plot water).
2. Pour water into a nearby well.
3. Organize closed loop circulation with a second radiator, which sinks to the bottom of the well.

Performance Adjustment

As for the performance of the pump, it cannot be adjusted without using frequency converters. The acquisition of such a device will affect the cost of structures. different kind autotransformers will not help in solving the problem.

In order not to purchase expensive equipment, you can solve the problem in the following ways:

1. If the well is less than 10 m deep, it is allowed to use circulation pump used in heating systems. It is only necessary to choose the necessary power.
2. If desired, you can limit the flow of water to the radiator using the type. He will dump excess water back into the well.

Advantages and disadvantages of the system

It is worth immediately highlighting several advantages that the design of such an air conditioner has:

1. With the help of the system, you can both cool the room and warm it up.
2. The design is much simpler when compared with a split system.
3. Even if you buy pipes and a pump, the total cost of assembling the structure will not be very high.

We have already talked about the shortcomings. These include difficulties in adjusting the water supply, as well as discharge. This system cannot be used in apartments, as you are unlikely to find a similar source of cold water. Of course, this type of system cannot be installed in a car either.

Refrigerator as a base

The idea is very interesting, because there are no differences from the split system in the design of the refrigerator. A refrigerant is also used, which heats up on the one hand, and takes heat on the other. Few tried to standing structure from refrigerators. But you can think a little and imagine how to make an air conditioner out of a refrigerator:

1. First you need to cut out two heat exchangers, while the compressor cannot be turned off. Otherwise, freon will leave the system and you will have to spend money on refueling.
2. Next, you need to move the condenser and compressor outside the room that is planned to be cooled.
3. The part that was previously a freezer needs to be mounted in the room.
4. In order for cooling to be carried out much faster, install a fan that will blow on the heat exchanger. You can put a homemade compressor to increase power. From the air conditioner compressor truck you can make a good design that will allow you to cool large area.
5. Of course, you will not need a regular control unit and a sensor that are set to a certain temperature. Therefore, you will have to install a temperature controller. Otherwise, the compressor will simply break down, as it is not able to work smoothly for a long time.

Is there enough power?

It should be noted that refrigerators maximum power about 400 watts. Even with a rough calculation, you can understand that this power is enough for a maximum of 4 square meters.

Moreover, this is only in theory, but it will be much more difficult to implement everything in practice, since the area that such a design can cool is even smaller. Of course, a homemade air conditioner from the refrigerator can cool small room, for example, closet. And in the summer it will be possible to store homemade preparations in it. But you have to make high-quality thermal insulation.

Consumption ecology. Manor: In summer period The issue of air conditioning is particularly acute. When it's hot outside, you want to have a corner where you can hide from it. It happens to buy ready system air conditioning no facilities or possibility. Then a homemade air conditioner from improvised means will come to the rescue.

In the summer, the issue of air conditioning is especially acute. When it's hot outside, you want to have a corner where you can hide from it. It happens that there is no money or opportunity to buy a ready-made air conditioning system. Then a homemade air conditioner from improvised means will come to the rescue. Especially well, such a device will fit into the interior of the cottage or country house, but it can also be successfully used in an apartment. It is better to start making the air conditioner in advance, before the hot days have come. Since it is not known how long it will take someone who has no experience in such matters.

WHAT ARE HOME-MADE AIR CONDITIONERS?

If you decide to make such a complex device as an air conditioner yourself, then you must first decide what can be used for this. Very often you can hear that the air conditioner was made from an old refrigerator.

Indeed, both devices serve practically the same purpose - to produce cold and cool something. The refrigerator cools food, the use of the air conditioner is wider, it cools the room, the people who are there, as well as everything that falls under its radius of action.

THE MOST POPULAR WAY TO MAKE AN AIR CONDITIONER FROM AN OLD REFRIGERATOR

In order to make a homemade air conditioner from the refrigerator, you need to find an old unnecessary freezer which is still in working order. If you do not have it, then you can buy someone else's by finding it on the ad.

To work, you need a household electric jigsaw. With it, you can make curly cuts on metal surfaces. A corrugated pipe is suitable as a drainage tube. It weighs less than pipes made of other materials. You will need insulating material and insulation, as well as mounting foam. Fans are needed for cooling, it is better to have two of them.

You should start creating a home-made air conditioning device by cutting a hole in the freezer. An electric jigsaw will help with this. It is easy to make with it round hole about 10 cm in diameter, into which the drainage tube will then be inserted. The rubber seal is removed so that air can flow in well.

The tube that is inserted into the chamber should be sealed with warm insulation. You can also use for this mounting foam. And only after that fans are mounted, one of which should blow the compressor of our new air conditioner.

ALTERNATIVE WAY TO CREATE

For the second method, you will need a radiator removed from the refrigerator, as well as an extractor hood. A radiator is mounted from the back of the hood. So, the exhaust device will be able to pass air flow through the radiator, cooling it, and then releasing it into the room.

After that, two hoses are connected to the device. One of them is brought to the sink, and the other to the plumbing system. Fastening is carried out by homemade coasters. Under the finished air conditioner, it is imperative to substitute a drip tray to collect condensate, which will need to be drained regularly.

The equipment works like this. Air enters the hood, cools in the radiator, through which water flows from the water supply. Ideally, the water should be cold, that is, flow from a well or from a well. Ordinary tap water, unfortunately, will not give the effect we need and will cool the room slightly.

OTHER WAYS OF MANUFACTURING THE AIR CONDITIONER

What else can you make an air conditioner out of? There are even easier and cheaper ways to assemble an air conditioner from improvised means. One of them is an air conditioner made from simple plastic bottles and a fan. The bottles are filled with water and placed in front of a fan with a small gap. The water must be pre-cooled in the freezer. When the water warms up, it will have to be replaced with a new one.

The effect of such an “air conditioner” is slightly superior to the effect of just a fan without water, since here there is also cooling, and not just the movement of air masses.

Another option also applies to simple designs, but more original and effective. Take a copper tube of small diameter and rubber hose. The tube will serve as an impromptu radiator. It is twisted into a spiral. The hose is needed in order to connect our "radiator" to a faucet with flowing cold water. The tube must be exactly copper, because copper bends better than other materials and has a high thermal conductivity. Clamps and sealant are needed to attach the hose.

A fan is placed behind the radiator. The result will be somewhat more impressive than from the first method with bottles. True efficiency will largely depend on the power of the fan.

Another option for which you need a car radiator. It is much more difficult to make such a design than the previous two, it will make more noise, but the effect will also be more significant.

The fan must be connected to a power outlet using a 12V adapter. The adapter is purchased ready-made, or assembled from the power supply of an old computer. The system will help to cool the air in the room by several degrees. Exact value will depend on factors such as:

• Fan power;
• Radiator size;
• The presence of air pockets inside the radiator.

It is better to prefer a radiator from a domestic car for this purpose. You will also need a casing and accessories for mounting the fan. The cost of such an air conditioner will not exceed 3-4 thousand rubles.

A MORE COMPLEX AIR CONDITIONING DEVICE

It is not so easy to make such a device, and instructions may even be required. But it can cool a room up to 30 square meters. m. In the summer it is convenient to install it in a window, where it will simultaneously not only cool the air, but also contribute to greater ventilation in the room. In winter, when the air is often dry, the humidifier included in the air conditioner will saturate it with moisture.

Air passes through the grate and enters the oil filter, where it is freed from dirt and dust. Then it enters the humidifier, and then exits the room through the grate.

It is possible to weaken the noise from the operating equipment if an electric lamp or other device is connected in series to the fan circuit. Its power should be such as to minimize the noise effect. The illuminated lamp is an indicator of equipment operation.

The humidifier looks like a box through which gauze wicks pass. Holes for them are made every half a centimeter, and their diameter is about 3 mm.

The box has 8 rows of such holes. On top of the box there is a tank with a capacity of 1.5-2 liters, in which there is water. The wicks serve to ensure that water gets into the inside of the device through them, where it evaporates and humidifies the air, which then enters the room. Excess water, however, remains in a special tray.

By the way, the pallet does not need to be emptied. After all, the water from it rises again through the same wicks, evaporates and moistens the air again. The air conditioner has an oil filter that looks like wooden frame with wire mesh. Its cell size is very small, about 1x1 mm. The mesh is lubricated with vaseline oil. After a period of time when the filter becomes dirty (usually once or twice a month), it should be washed with hot water.

BENEFITS OF USING A HOMEMADE AIR CONDITIONING SYSTEM

So, we have considered. What are the benefits of using it? The main advantages of homemade devices presented above are:

1. Saving money.
2. Great for garden use and country house where it is impractical to build a professional system. People come to the dacha mainly in summer, and in winter, an expensive device without security can be stolen.
3. The opportunity to get a lot of positive emotions from the knowledge that you were able to do such a thing with your own hands. useful thing like an air conditioner.
4. Gaining new knowledge and experience in the field of remaking one thing into another.
5. There is no need for expensive maintenance and preventive maintenance equipment.
6. Comfort and vivacity in the room due to air cooling in summer.
7. No need to periodically purchase and change filters, since they are absent in almost all the considered devices.

As it turned out, making a homemade air conditioner in an apartment is not so difficult. And anyone can handle this. It is only necessary to delve into the principle by which the usual household air conditioner and start taking action. published

During hot weather, we all face the problem of dry air inside heated buildings, especially this negative impact felt in high-rise buildings. Many people cannot afford to buy a normal climate system, but it turns out that it is quite possible to make an air conditioner from various materials at hand. How exactly - this article will tell you.

Everyone knows that an air conditioner is designed to be maintained in an enclosed space. optimal temperature, providing comfortable accommodation. All models modern air conditioners are divided into two main types: compressor type and evaporation. Many craftsmen come up with various very original designs air conditioners for the home, which are based on evaporation of moisture under the active influence of heat.

Even our ancestors often used home-made devices to cool the room, when there was no mention of such a word - the climate system - in the lexicon. To do this, a thick canvas fabric was hung on the transom of a window or window leaf, and the other end was lowered into a basin of water. Hot air he dried the canvas from the street and a chilled and damp stream entered the room. Many people still make such an original and simple home-made air conditioner, they just insert a fan into the window to significantly speed up the blowing process.

So, to make a simple homemade air conditioner from improvised means, you will need:

• small fan, which can be bought in a store or in the market from grandfathers;
• container with cold water;
• dense fabric, you can use a terry towel;
• wire for the manufacture of the frame.

A strong frame is made of wire, we insert a fan into the window, in front of it with inside the frame is fixed with a towel fixed on it, the second end of which is lowered into a container with cold water.

Such a simple household home-made air conditioner at home can be built by any user, for the lazy, the option shown in the photo below is suitable.

We can say that this option is the most silent device. Among the shortcomings: it is necessary periodically pour cold water.

Plastic containers + water

One more pretty original version with the participation of a domestic fan, and for its manufacture the following components are necessary:

• plastic bottles different shapes and containers;
• floor fan;
• water.

For the best effect, place bottles of water in the freezer and freeze, while there is one trick - so that the ice then melts slowly, add a little coarse salt to the water.

The fan is installed near the table, and rows of bottles are lined up in front of it at a short distance from each other. The whole process is very simple: the ice melts, taking heat from the air, and the fan delivers cooled air to the right place. We change bottles periodically. If there is no place to place them on a plane, then you can fix them at the back of the household appliance. Such an air conditioner made of plastic bottles takes up little space and works almost silently, but its effect is slightly worse than the original version.

Copper tube+hose

Another option for air conditioning, which is quite easy to make at home from a table fan. To do this, you need to prepare:

• garden rubber or plastic hose for watering;
• thin copper tube;
• table fan.

The tube is bent in a circle, leaving a gap between the sections for the unhindered passage of the air flow, and fixed to the device limiter with clamps. One end connects to a faucet and the other to a drain. The cooling process is also simple - water circulates through the tube and cools it, the air current passing through homemade device, cools down.

The disadvantage of the system is that it can only be installed in the kitchen, while there is a significant consumption of water.

Ice and cooler

Do-it-yourself mini-air conditioner can be made from the following parts:

• container made of tin or plastic;
• self-tapping screws;
• drill;
• old CD;
• cooler (mini-fan);
• USB cable;

We drill the container in the lower part around the entire perimeter to suck in air, carefully drill the disk in several places. At a distance of 1/3 from the bottom, we screw in three self-tapping screws that will hold the disk in the desired position. Ice is laid on the CD, the whole structure is closed with a lid, on which the cooler is rigidly installed - it will draw out the cooled air from the inside. We connect the old USB cable to the cooler, and insert the other end into the connector system block or laptop.

There is a video for users to study the entire manufacturing process:

Unique bottle device

As everyone knows, Africa is the hottest continent on our planet, in some regions almost all year round extreme heat and no electricity. Craftsmen from Bangladesh came up with a very original plastic bottle air conditioner based on a physical law: the natural temperature of a gas decreases when passing through a sharp contraction and a maximum expansion afterwards.

As the prototype showed, the air at the outlet loses about 5 degrees - excellent result without the use of technical means.

A unique device is made very simply - we give an algorithm for all actions.

1. We cut out a rectangle from plywood or fiberboard corresponding to the window opening.
2. We measure how many bottles fit on it, installed close to each other. It is better to choose a container designed for 2 liters.
3. We drill pre-planned holes in the sheet - their diameter is identical to the size of the neck of the plastic container.
4. We insert the bottles one by one, removing the cork and cutting off one third, into the holes, and fix them. If there are gaps, then fill them with silicone sealant.
5. We fix the made air conditioner in the window with bottles out.

This is probably the most environmentally friendly device in the world - what else is needed in the heat in the country.

Radiator+fan

There is no limit to the fantasies of home masters - almost any old technology they are trying to update and give it a second life: for example, a miracle air conditioner made by hand from an old car aluminum radiator.

A simple design is made up of a radiator, a room fan and a case from an old computer system unit - a radiator and a fan are mounted inside the unit, water is supplied and drained through specially removed tubes. Handles are attached to the case for easy portability. Gifted craftsmen install power supply with different voltage, so that there are several modes of operation, and the control will be carried out by the built-in switch.

On the tubes, hoses made of durable rubber are fixed with clamps, one serves to supply water, and the second works to drain. The advantage of such a miniature do-it-yourself split system is high water flow rate through the main unit and fast fan rotation. At the same time, condensation does not appear on the radiator, constructed from aluminum plates.

Unusual use of the freezer

From an old refrigerator, with some skill and a flight of fancy, some homeowners make an air conditioner that install in window opening or a special niche with access to the street. The freezer compartment is inserted in such a way that rear end was completely outside, because there is a radiator, which is an active source of heat. The main cold is concentrated inside the chamber, so we make a hole in the door and install a fan of the required size.

From the sides of the chamber, which will be located outside, you can drill holes for the influx of air mass. This design of the refrigerator will provide an influx of coolness into the room during hot summer days.

Air conditioning from the refrigerator can be made using the old portable household item.

1. We take the case from the mobile version of the refrigerator, which has not been working for a long time, but keeps the tightness well, remove the cover, install two coolers from the computer on it. To do this, outline the size of each, then drill with a drill and mechanical jigsaw round holes.
2. We insert the coolers into place and seal all the cracks with sealant.
3. We put ice inside the chamber - you can freeze in advance in a plastic container that is suitable in size to the internal volume of the old device, the required amount.
4. We close the lid tightly and turn on the fans using a specially purchased device or connect them to a PC. The ice melts for quite a long time, and the air conditioner from the old mobile refrigerator, made by hand, manages to cool the room perfectly.
5. Then the water is poured into the container, and a new portion of ice is placed in its place.

As you can see, making an air conditioner with your own hands is quite realistic and without special technical skills. All of the above homemade options air conditioners are absolutely harmless and made from environmentally friendly components, many of them help to significantly save not only on the purchase of expensive equipment, but also on its installation.

Original designs will help you avoid heat stroke while in the country, and for motorists who have preserved old stove radiator such an original air conditioner is suitable, the manufacturing method of which is shown in the video:

How to make an air conditioner with your own hands? Is it possible and effective? Here are some recommendations from the rubric « do it yourself air conditioner » . And they really help cool the air in the room.

What are air conditioners made of?

Videos of air conditioners, assembled by hand, fill the network on hot summer days. Inventive House master can build an air cooler from empty plastic bottles, metal tube, an old car radiator and even a bunch of thorns. And aerobatics is the construction of an air conditioner with your own hands from a refrigerator at home.

Air conditioner from a pipe or hose

How to make an air conditioner copper tube? It bends easily and conducts cold well, but you can even use a rubber hose for watering. We twist the tube in a flat spiral, avoiding kinks. We connect one end to the water supply, the other to drain the water.

We attach this structure with the help of wires to the front grille of the room fan, turn on the water with low pressure.
Air passing through a cold tube will also be cooled. See the video for details of the process. The air conditioner is up and running!

Used container air conditioner

DIY air conditioner from plastic bottles. What could be easier!

Pour ice water into plastic bottles (you can freeze them altogether), put them in front of a room fan, leaving air gaps of about 1 centimeter. Turn on the fan and enjoy the coolness.

An ideal way to cool a small room.

Place a tray under the bottles to prevent condensation from dripping onto the floor. And inside the bottles, add a little salt, then the water will keep cool longer.

Air conditioning from a car radiator

We attach two tubes to the radiator from the car (with a fan): water is supplied one by one, it flows out of the other.

The system is connected to the network using a 12-volt network adapter. Water is passed through the tubes with a small pressure, and the fan drives cool air.

This is the most effective method structures home air conditioner from what is at hand.

Refrigerator air conditioner

It is not so difficult to assemble an air conditioner of this type with your own hands. You need to take: 2 fans, a corrugated pipe, the same diameter as one of the fans, and mounting foam.

• We drill a hole in the freezer door, insert the end of the corrugation and one fan into it. Foam around carefully;
• We install a second fan to blow the compressor;
• We stretch the end of the pipe into the room that needs to be cooled.

A simple system works flawlessly.
