How to make an air conditioner from a cooler. Compression device and its design

use freon for homemade air conditioner traditionally unreasonable - the solution is within the power of a professional, carries many difficulties. Today we will look at how to make an air cooler out of an ice bucket, we will mention the practical aspects of using processor coolers. We do not promise to make the air conditioner ourselves. But a good cooling fan is for everyone.

Where to get cold for a homemade air conditioner

The refrigerator works on the principle heat pump like an air conditioner. Takes the heat out freezer, renders warm kitchen. The principle of operation of the air conditioner is based on this. It becomes possible thanks to the transfer of freon from one place to another. If the power of the heating device is equivalent to the energy spent, in the case of air conditioners it can exceed the costs by several times (efficiency up to 300%). It is possible to take the cold in a homemade air conditioner with the help of ice. In Russia, they made pits: they stored food in the winter in the summer. We will do the same with a homemade air conditioner.

It is necessary to put ice in a container, blow it with a stream of air. For a homemade air conditioner, any fan is suitable. It is logical to take a floor standing asynchronous motor. Safely? The motor windings are made of a conductor with varnish insulation - the contacts are covered with cambric. If you knock over a homemade air conditioner, it will short circuit. Either traffic jams will fly out, a child will come into a puddle.

A way out for a homemade air conditioner has been found. At the cost of power reduction (apartment homemade design not cool) make the appliance safe. Recall the classification of devices in terms of electrical safety:

For the safety of a homemade air conditioner, it is enough to power it with non-hazardous voltage. Every home has a personal computer or similar gadget. Coolers are used in most system units - it is logical to use a home-made air conditioner. Computer fans are powered by 12V, indicated by the yellow tube wires on the plug inside the case. Difficulty finding a source: voltage is inherent in professional radio stations, other devices (from the field of object protection). Wind the transformer, rectify the current?

Enthusiasts found a way out. On the other end of the computer connector, the red wire is 5VDC. If you power the cooler through the indicated place, the number of revolutions decreases. This alignment is acceptable, in terms of accessibility, there is a big plus. Take your charger cell phone take a close look at the markings:

  • The first line is the input voltage, most often 220-240 V with a frequency of 50-60 Hz.
  • The second line shows the output voltage. Constant, is 5 V in amplitude.

In most families there are old mobiles that are out of order, but the power supplies are intact. It is enough to cut off the connector, measure the voltage with a tester, find the necessary wires, connect properly - we get a workable cooler for a home-made air conditioner. Find a 12 V power supply - it will be great. The blades will begin to work to their fullest. Remember: the noise level also increases. The buzzing does not give rest - it is necessary to lubricate the fan axis. Often the difficulty lies in misalignment - there is nothing you can do to help. A normal cooler works silently.

In cheap hoods are asynchronous motors low weight, small dimensions (in expensive ones - with a split pole). Apply with an eye to electrical safety. Aspects discussed above. Remember: 220V voltage combination alternating current and the water is extremely dangerous.

How to make an air conditioner with your own hands

A separate design of a home-made air conditioner was proposed by an inventor from abroad. He suggested using an ice bucket (popular across the sea). It does not mean a bucket of tin on screens in movies. But the principle of operation of a homemade air conditioner is similar. The plastic container is double, the inner one does not touch the outer one. A layer of air plays the role of a heat insulator in a homemade air conditioner - the design is not new. The idea has always been used in thermoses. Multicookers are included in the specified class of devices. Magic pots are not insulated in any way, but keep the dishes hot - it helps to save energy.

Similar buckets have become widespread in America. To create a homemade air conditioner, both closer to the lid are perforated special drill(with a knife). Hole diameter 8 cm. Three holes are enough. A guide is inserted into each - a nozzle (it is possible without). A fan is built into the lid. In America, the voltage is smaller than ours (the frequency is higher), but the path is dangerous. It is dangerous to overturn the bucket. Find a high power DC motor.

Blowing from top to bottom, the fan promotes air flows through the ice, leaving the holes-nozzles, a gust of draft cools the air. Sometimes you have to replenish the stocks of cold in a bucket. Can be replaced with cooler Electrical engine- the idea is relatively safe. Suitable cell phone adapter, other household appliances(walkie-talkies, laptops, iPad) for food - often sold on the market. Last resort, from the old system block remove the power module with wires - it is more logical to use 12 V, bringing the speed closer to the nominal.

Abroad, it is recommended to use chest freezer. It costs 5,000 rubles in electronic markets - the toad will spoil good thing for the sake of cooling. Find a used one for a couple of hundred - you can adapt the chest. The principle is the same, only its walls are often metal, but the shape is oblong. The outlet hole is drilled in the lid, opposite the inlet. We remind you: the fan works for blowing. Regarding domestic Kulibins: an expensive purchased design is imitated.

For a homemade air conditioner, a couple of mayonnaise buckets are suitable, by all means different size. The outer large is supplied in the bottom area with a triple of holes, as shown above. It has an internal hole in the area of ​​​​the lid. So that the buckets do not touch each other, place a segment of a wide plastic pipe. Spacers on the sides will not allow the container to swing inside (it is possible without). Ice is placed inside, the fan blows from above, blowing the cold supply with a stream of air. As a result, the temperature in the room will drop, the atmosphere will be humidified.

The advantage of the design: it easily turns into a humidifier in winter, not cooling, but saturating the microclimate with moisture. If the relative humidity falls below 40%, it will lead to a decrease in the immunity of the living people. The device of the air conditioner involves the circulation of air through a wet container that improves the atmosphere. Remember: relative humidity does not exceed 70%, otherwise fungus growth is possible. high humidity harmful to health.

The stores sell the construction of concentric circular saws. By placing or removing the outer blade, the master changes the diameter of the hole made by the nozzle. It is quite suitable for wood milling.

First you need to clearly understand that the on-board network of the car has a voltage of 12 volts (we don’t take trucks - let them fry there). Most affordable way connect to the onboard network - cigarette lighter socket.

An old forgotten container is taken (refrigerator bag),

saloon stove radiator (suitable for size),

submersible pump hic, a couple of fans (size also matters), tubes, wires, and an old mobile charger.

We strengthen the pump at the bottom of the container. by the way, the pump can be taken from an aquarium or from a car windshield washer barrel. Pull the wires out.

In the lid of the cooler bag, we make a square cutout from the inside, and two round cutouts for fans on the outside. We screw the fans, combine their wiring.

On the inside We strengthen the radiator caps (pipes down). You can put on silicone.

For convenience, we attach the lid to the body with a piano loop (it was lying around in the garage).

We connect the pump outlet to the radiator inlet on the cover. You can also attach a hose to the radiator outlet so that the water does not murmur much. We bring all the wires to the wires of the used charger and this whole System is ready to be connected to the cigarette lighter!

How does it all work?

Ice is poured into the container (cold accumulators are possible), water is poured. When turned on, the pump starts pumping cold water from the tank to the radiator, and the fans blow cooled air out. Eco friendly? 100% Economical? 100% Effective - yes, but only about an hour, then you need to fill in new ice. This system can be projected to larger sizes-volumes. Moreover, you can use it indoors (then you can also make 220V).

USB air conditioner

Hot time. But in many houses or offices, unfortunately, there are no air conditioners, and therefore you have to sit and languish in the heat. But there is a way out! You can make a very simple USB air conditioner from improvised means.

We will need:

1) Unnecessary CD\DVD disc

2) Container (plastic, metal, whatever)

3) A few screws or sticks

4) Cooler, or other ventilating device

Device:

1) There is nothing complicated in the manufacture of such an air conditioner. Take your container and visually divide it into 3 parts.

2) Take a disc and drill/drill lots and lots of holes in it. And if you have a metal mesh, an unnecessary sieve, then you can use it.

3) Insert this our resulting sieve at a distance of 1/3 from the bottom.

4) In this lower part, on the side of the glass, dig holes - warm air will flow into them.

5) put ice on top of the sieve. When melting, all this will drain into the lower compartment, and this water can then simply be drained.

6) Well, the final step - on top of this whole structure, you need to fix the cooler blowing outward. I cut a square hole in the lid for it, and just glued it on it, and closed the lid.

7) It remains only to attach the USB cable to the wire. To do this, cut off the end that needs to be hooked to the fan, and hook the red and black wires to the contacts.

DIY air conditioner

Autonomous evaporative air conditioner is designed for residential and public premises up to 30 square meters. m. V winter period when the relative humidity is low, the air conditioner is used to humidify the air. AT summer period you can install it in a window, it will simultaneously increase ventilation and cool the air. The operation of an air conditioner is simple.

Air enters it through the grate, is cleaned of dust in the oil filter, passes through the humidifier and is fed into the room through the guide grate. Axial fan(with a capacity of 300 cubic meters / hour) sometimes makes noise, which is annoying. To reduce noise in wiring diagram fan in series with it electric lamp or other resistance. The power of the lamp is chosen so that the noise is minimal. If the lamp is on, the hole serves as an indicator of the operation of the air conditioner.

The humidifier of the air conditioner is a box through which hygroscopic wicks made of gauze, cambric, etc. are passed. Hole diameters for wicks - 3 mm, pitch - 5 mm. AT cross section boxes - 8 rows of holes.

On the box on the stand - a tank with a capacity of 1.5-2 liters. Water is poured into the tank. Through the wicks, it descends from the tank down, evaporates along the way, moistening the air, and accumulates in the pan if it does not have time to evaporate. After emptying the tank, the water from the sump rises up through the wicks and evaporates again. To prevent the wicks from rotting, it is better to turn on the air conditioner only after the water has completely evaporated.

The oil filter is wooden frame to which the wire mesh is attached. The grid cell size is 1x1 mm. The mesh is lubricated with vaseline oil. When the filter becomes dirty, wash it hot water(1-2 times) per month.

Evaporative air conditioning has been tested in several apartments with positive results.

COOLER-HUMIDIFIER. The principle of operation of the room cooler-humidifier is based on the need a large number heat to evaporate water. About 3 liters of water are poured into the drip tray (8) installed horizontally.

Built-in tray sections made of hygroscopic material (can be used regular fabric for towels) constantly absorb water, and a room fan placed (from the side of the street) in front of the sections constantly dries them with a continuous stream of air. The device is installed in the window. At the same time, the temperature difference at the inlet and outlet is approximately 10 degrees, and the water flow (for climate Central Asia) about 1 liter per hour. Air intake can be done both from the street and from the room by adjusting the dampers. There are blinds (12) for directing the air flow, and a hatch (13) for pouring water. Dust coming with air settles in the pan. For the manufacture of this device, you can use wooden bars and pressed and well-painted cardboard or plywood.

Wanting to save money, they use a hand-made air conditioner to cool the air. Homemade devices operate on the principle of lowering the temperature of a surface when water turns into steam.

The device of the factory and homemade air conditioner

The design of such household appliance like air conditioning, quite complex. The air cooling system operates due to the transfer of heat from one zone to another: in the hot season - from the house to the street, and in the winter months - from the space outside the walls of the apartment inside it. A special substance is responsible for the circulation of warm air masses - freon, which, if necessary, boils and passes into a gaseous state, acquiring low temperature.

The device is complex, because it consists of two blocks

The air temperature in the room and the pressure of freon, called the refrigerant, are controlled by an electronic control unit that starts working after receiving signals from special sensors. Since the operation of the air conditioner is difficult process, making an air cooling system on your own is not easy.

Homemade air conditioners are distinguished by the fact that they come into action as a result of blowing room air through cold objects. This object can be pieces of ice or cold-producing devices used to store food in bags during transport in the summer.

Warm air turns cold when pushed through ice

Making an air conditioner with your own hands

All self-made coolers are two-part units:

  • a block that lowers the temperature of the air masses;
  • an element that distributes the cooled medium throughout the room of the apartment.

Ice and draft

A self-assembled air conditioner may consist of a plastic bottle filled with frozen liquid and a conventional fan. Such a cooler environment It is customary to place it on a table next to a running fan.

Plastic bottles tied to the fan grill

If desired, the design of the air conditioner can be made more complex: use a wire basket suspended from the bars of the fan grille. This container is filled with ice cubes.

If possible, then a home-made air conditioner, so that it works better, does not interfere with improvement. This implies the abandonment of the plastic bottle and the use of a "cold accumulator" - a container with a special liquid used in cooler bags. The efficiency of such an installation for changing the microclimate is determined by the size of the vessel with pieces of ice.

More ice can fit in buckets, which means that the air conditioner will work longer

A home-made air conditioner, functioning thanks to ice and a draft, will cool the air in the room much more efficiently if you assemble the installation as follows:

  1. take a very large plastic vessel, not without a tight lid;
  2. make 2 holes in the lid of the container, and the diameter of the first must match the parameters of the fan grill, and the size of the second can be 5 or 10 cm;
  3. insert into the second slot and securely fasten the corner fitting by 5 or 10 cm, which will allow a branch in the shape of the letter “G” to form above the cover;
  4. immerse in the first hole and fix the fan well, using self-tapping screws immersed in the container lid;
  5. fill a tightly closed container with crushed ice bottles, frozen liquid or a cold accumulator.

The fan of the device, made according to the instructions, will push warm air masses through the ice vessel and give cold streams coming out of the elbow fitting. Since the body of the container is insulated from heat, the ice will not melt instantly, which means it will ensure the operation of the air conditioner for long hours.

Fan and cold water

Together with a fan, for the construction of an air conditioner, you can use not frozen, but simply chilled water, which will create a dynamic flow that runs through the copper radiator grille. In other words, the fan blades will draw air into the spiral of a copper tube, through which water will flow from the water supply system, which has a stable temperature of 14-16 degrees Celsius. With this approach to the design of the air conditioner, an inexhaustible source of cold air will turn out.

The air is cooled thanks to the continuous flow of cold water and the operation of the fan

But you will have to pay for the water spent, so it is much more reasonable to make an air conditioner from a fan and cold water as follows:

  1. insert 2 hoses through the lid into the plastic barrel (one should be longer, the other shorter);
  2. next to the neck of the container, attach an aquarium compressor equipped with a pipe that sucks in water and is connected to a hose that goes from the lid to the bottom of the barrel;
  3. attach a fan to the lid of the vessel, the grille of which must be provided with a spiral of copper tube;
  4. combine one edge of the copper spiral with the compressor nozzle, and the other with a short hose, which occupies only a quarter of the height of the barrel;
  5. connect to the end of a short hose check valve, which blocks the movement of fluid from the barrel to the hose.

After the compressor is activated, such an air conditioner comes into working condition, since the cooling coil attached to the fan grill is filled with icy water from the bottom of the tank. The liquid is given a certain direction: running along the spiral, it will merge into the upper zone, where it is located relatively warm water. The result of such an organization of the movement of a liquid medium is the supply of only cooled liquid to the fan blades.

From an old refrigerator

Trying to make an air conditioner from an unused refrigerator is only for men who are experienced in repair work. At the same time, the design of an air cooler involves the use of household appliances for freezing products, the components of which are a cooling radiator (freezer), a refrigerant, a compressor and a condenser, which is a grill at the back of the refrigerator.

The parts responsible for cooling the air are located inside the chamber household appliance

To assemble an air conditioner from the parts of an old refrigerator, you need to do the following:

  1. remove the doors from the household appliance that block access to both cameras;
  2. carefully, in order to avoid damage to the walls, insert a fan powered by the mains into the freezer;
  3. using a drill, make several holes with a diameter of 1.5 cm in the lower zone of the side walls of the refrigerator;
  4. place the refrigerator so that the rear grille is outside the room in which you want to make the air cool (you can place the household appliance in doorway, sealing the area between the body and the edges of the opening with a film of polyethylene).

If the previous point is not feasible, then it is necessary to do this: open the refrigerant supply line and remove only the condenser outside the room, using copper pipes for this. True, such a solution to the problem involves pouring a new portion of freon into the system.

From a portable cooler

When it is decided to make an air conditioner from a portable refrigerator, in addition to the case from a small household appliance, 2 more items must be used:

  • radiator;
  • submersible pump.

To make such an installation, you need to understand the connection of wires

From a portable refrigerator, a home-made air cooler is built in several stages:

  1. a radiator of a suitable size is mounted in the “box” of the apparatus;
  2. a submersible pump (taken from an aquarium or a car washer) is attached to the bottom of the refrigerator case;
  3. wires lead out of the chamber;
  4. a square-shaped hole is drilled in the refrigerator lid (from inside the case), and 2 round holes that will be needed for ventilation;
  5. inside the chamber, using silicone, fix the radiator;
  6. the pump outlet and the radiator inlet are connected;
  7. a hose is put on the radiator outlet, which will help make the device quieter.

The created air conditioner will cool the air by filling the refrigerator container with pieces of ice or cold water, which, under the pressure of the pump, will enter the radiator and, under the influence of the fan, form cold air currents.

From a car radiator

Thinking of making a cooling device from car radiator, you will need to prepare the following details:

  • fan (from the car);
  • radiator (from the car);
  • computer power supply case.

To assemble an air cooler from these elements, you need to perform certain tasks:

  1. mount on back wall a radiator on the front of the power supply case, and a fan on the front, which will allow the air flow to exit the radiator and be directed towards the fan;
  2. attach handles to the created design so that it is convenient to move it.

At first glance, the device seems complicated

Since the power supply unit produces different voltages, the air conditioner can be turned on in various modes of supplying cooled air. To correct work homemade device you only need to adjust the built-in speed switch.

The radiator used to build the air conditioner is different lamellar view. Rubber hoses are put on it, fixed with clamps. Hollow tubes are needed to supply and output water. In this case, the liquid must flow from one place to another very quickly, for which the fan motor works on high speed, providing an instant decrease in temperature in the room.

Other options

An air conditioner can be made from a car air cleaner and a standard fan, but this method is difficult and costly.

Instructions for building this air cooler require:

  • connect the fan to the air cleaner using a hose or pipe;
  • make a case for air conditioner parts using any available materials;
  • make a filter out of a fine-meshed mesh (fold it 4 times) and attach it to the lower zone of the case;
  • fill the air cleaner tank with water and connect the system to the mains.

The device made will function due to the fact that the fan distills the air masses into the evaporation chamber, which contains water and cools the medium that has entered it. Outside the air conditioner, cool air will be released after passing through the holes in the mesh.

1 - body; 2 - wire mesh; 3 - air duct; 4 - openings for the exit of cooled air; 5 - flange connection; 6 - fan with motor

You can also create a spray air conditioner with your own hands. The device is assembled from a large container filled with water and an air duct. For this air conditioner to work, you need to do the following:

  • insert a spray gun into the evaporation chamber, the nozzle of which will allow you to regulate the intake of liquid from the tank;
  • associate installation with ventilation system which helps to cool the air masses.

Advantages and disadvantages of homemade air conditioners

The undoubted advantages of air conditioners assembled independently include:

  • real performance, because such installations really cool the air in the room;
  • the possibility of assembling from improvised materials, for which it was not necessary to spend finances.

The ice in the bucket gives off cold, which spreads around the room under the action of a fan

But home-made air coolers also reveal a number of significant drawbacks:

  • the operating time is limited by the amount of ice that has to be constantly replenished;
  • the inability of the installation to cool the air in all rooms at once, because while one room is blown with cold streams, a refrigerator is working in the other, freezing ice and heating the air because of this;
  • significant energy consumption, which is due to the need to replenish stocks of ice chips;
  • strong humidification of the air in the room, which leads to its passage through cold water or ice.

The air in the room will not become humid, which does not mean that it will not cause the same harm to a person as heat, if instead of ice, the air conditioner is loaded with cold accumulators. However, they do not convert to water.

All considered homemade air coolers function without problems. They are a real salvation from the heat when the situation is hopeless. True, the use of a do-it-yourself air conditioner causes a lot of trouble.

In the manufacture of a do-it-yourself refreshing device for the home, the principle of cooling the surface by evaporating water is most often used. Many variants of such devices are quite simple, so everyone can build a home-made cooling air conditioner at home with a minimum set of funds.

The simplest device for home

The simplest cooling device that does not require almost any material, financial, time, or intellectual costs will be the design of a fan and a wet towel. The towel is thrown over the mechanism, the air passes through, evaporating the water. The evaporation process cools the towel, so the passing air will become slightly cooler. This method can be slightly improved by lowering the end of the towel inside a container of water.

It will not be possible to cool the room in this way. But for individual use it will be effective.

Fan + plastic container. Option 1

The most common option for constructing an air conditioner from improvised means is a combination of a ventilation mechanism and plastic bottles with cold water or ice. You will need:

  • ventilation mechanism;
  • plastic or other containers;
  • ice/chilled water.

Action plan:

  1. The container is filled with cold water, frozen.
  2. Cooled, mounted to the fan grille or placed in front of it. Be sure to leave gaps of 1-2 cm for circulation, cooling the air flow.
  3. Consider a way to collect condensate, which will definitely appear.

The water needs to be changed periodically. You can make two sets at once, cooling them alternately.

Fan + plastic container. Option 2

  • cooler;
  • plastic containers (three two-liter and three half-liter);
  • foam tape.

Manufacturing:

  1. For two-liter containers, you need to cut off the bottom, drill holes inside. In one case - from below, in the other - from the side.
  2. Wrap the cooler with foam tape (for fixing, absorbing vibrations).
  3. Place the mechanism between the cut off parts so that the bottom of the bottle with side holes is at the bottom.
  4. Remove the bottom from two container lids.
  5. Inside two half-liter bottles on the side, make holes equal in diameter to the neck.
  6. Neck large capacity insert inside the small side hole, fix it inside the trimmed lid (you can use a long knife or other tool).
  7. The second, small, fix with the first in a similar way. Now the small bottles can rotate perpendicular to their bases.
  8. To plastic box with a cooler, attach a third half-liter container with ice.
  9. From above, cover it all with a two-liter bottle with two small ones attached.

Improvised homemade air conditioner plastic bottles ready to use. Air flow adjustable by rotating half-liter containers in two directions. Will be useful small room, for individual use.

Fan + copper pipe

You will need:

  • fan mechanism;
  • copper tube/rubber hose;
  • water pipes.

Mounting scheme:

  1. Wind the copper pipe/rubber hose to the protective fan grille and fix it. It is necessary to leave gaps between the turns of the tube, hose for free circulation, air cooling. There should be no strong bends.
  2. Connect one end of the copper tube/rubber hose to the faucet. Take the second one to the sink. In this position, the structure can be fixed.
  3. Open the water under low pressure.
  4. Turn on the fan mechanism.
  5. Adjust airflow direction.

Such a unit is able to cool a medium-sized room. Can be costly due to the large amount of water supplied.

container + cooler

Necessary materials:

  • plastic container with a volume of 1.5-2 liters;
  • minifan from a computer power supply;
  • corrugated plastic siphon;
  • glue gun;
  • mounting knife.

How to make a homemade air conditioner, assembly design:

  1. Inside the lid of the container, cut a hole slightly smaller than the minifan;
  2. Glue it to the lid so that the air flow is directed inside the container (using hot glue).
  3. Cut a hole for the siphon pipe.
  4. Cut off 25-30 cm from the corrugated plumbing siphon.
  5. Fix the resulting segment inside the container lid with a hot gun.
  6. Put ice inside the container.
  7. Close the lid tightly.
  8. Connect the minifan to the mains.

The direction of the cooled air can be adjusted with a siphon. If possible, it is better to use a large piece of ice. The air flow, getting into the container, will be able to circulate in it and cool more. In the case of small pieces of ice, there will be no such air circulation.

The direction of the cooled flow can be adjusted using a siphon. It is better to use a large piece of ice. The air flow, getting inside the container, will be able to circulate and cool more. With small pieces of ice, there will be no such circulation.

Radiator + auto fan

Source materials:

  • car radiator;
  • 12 V auto fan;
  • frame for fan mechanism;
  • case-fixator;
  • fastenings;
  • rubber tubes;
  • a set of clamps;
  • insulating tape;
  • sealant;
  • 12 V power supply.

Device instruction:

  1. The outlet for the radiator temperature sensor must first be closed with a tight plug.
  2. Fasten the radiator horizontally to the fixing panel.
  3. Fix the autofan so that the air flow is directed from the radiator into the room.
  4. Install with clamps rubber hoses to the radiator pipes.
  5. Connect the cold water supply hose to the faucet.
  6. Place the drain hose in a sink or bathtub.
  7. Place a drainage container under the structure.
  8. Eliminate air pockets inside the radiator.
  9. Connect to mains.

The device reduces the temperature by supplying cold water. The cooling time of the room depends on the speed of the autofan, the speed of the liquid supply. The power is low, it will cool a small room.

Old refrigerator + fan

Necessary:

  • old refrigerator;
  • plastic pipe;
  • two fan devices;
  • jigsaw;
  • assembly foam.

Manufacturing process:

  1. Cut a hole inside the refrigerator freezer door for the first mini fan.
  2. Fasten so that it blows air into the chamber.
  3. Drill another hole in the same place.
  4. Insert a plastic pipe inside the resulting hole to bring the cooled air out.
  5. Seal gaps tightly with mounting foam.
  6. For better heat dissipation, you can install a second cooler, the air flow from which will be directed to the condenser.
  7. Connect the structure to the network.

Improvised air conditioner from the old refrigeration plant can be a good alternative to the climate system. The principle of its operation is based on the supply of heat by freon from the evaporator to the condenser (like many air conditioners).

Fan + Peltier elements

Air conditioning on Peltier elements is a controversial device, the energy efficiency of which is low. It looks like an electronic double-sided plate with two wires. After connecting to electricity, one side heats up, the other cools. Device Diagram:

  1. Purchase Peltier elements (4-8 pcs).
  2. Attach with the heated side to the finned aluminum heatsink.
  3. Install the radiator so that it is cooled by fresh air.
  4. Attach a computer cooler to cooling surfaces to force room air in their direction.

The Peltier air conditioner cools the temperature, while consuming a large amount of energy. Half of the energy consumption is heating the second side.

This video demonstrates the process of creation, test experiments of a homemade cooling mechanism

The disadvantages of homemade air conditioning far outweigh the pros. Before embarking on manufacturing, it is necessary to weigh all the pros and cons well. If the construction of the already existing fan mechanism and a couple of bottles will cost nothing but the time spent (cooling, replacing containers), then more complex devices will require some material investments, a lot of time for their assembly, arrangement.

If you have been thinking about buying an air conditioner for a long time, but are not ready to spend a large amount on this purchase, the master class will be especially useful for you. Homemade air conditioning, made by hand, will create a cool home at any time of the year. To design this invention will require a minimum of experience, time and financial investment.

Benefits of a mini air conditioner:

  • Low cost (500-1000 rubles). Compared to the technology offered by manufacturers, home air conditioner comes out cheaper at least 20 times and does not require subsequent additional investments.
  • Manufacturing speed (1.5-2 hours). If you really wanted to get an air conditioner today, in the best scenario, manufacturers will bring and install it in a few hours, when you can make it faster as a home-made air conditioner.
  • Availability Supplies. You will find most of the materials and tools for the air conditioner at home, the rest you will find on construction market or department store.
  • Low power consumption. Experts calculated that an air conditioner without an energy-saving system works 450 hours a year, which is 1,000 rubles. Not much, but a homemade air conditioner will cost even less.
  • Possibility of rearrangement in any place of the apartment. A homemade air conditioner is lightweight, so it can be rearranged from the kitchen to the bedroom, from the bedroom to the hall and periodically change its position.
  • Security. The air flow coming from a homemade air conditioner is not so powerful, so it is impossible to catch a cold under it. This ensures the safety of you and your children.
Expendable materials:
  • Computer cooler - 2 pcs.
  • Large plastic or cardboard box - 1 pc.
  • Outlet pipes - 2 pcs.
  • Power supply (12 W) - 1 pc.
  • Plastic bottles cut in half - 2-4 pcs.


Additional tools:
  • Super glue.
  • Silicone adhesive.
  • Insulating tape.
The manufacture of the air conditioner should begin by connecting the power supply and the computer cooler. At first glance, coolers are capable of cooling the insides of a computer and their power is not enough to provide a similar effect for an entire room. In fact, the powerful air circulation that occurs inside the box creates a strong flow that instantly spreads over the entire area. If the connection is made correctly, the coolers will work immediately after they are connected to the outlet.


Insert the cooler into the cut out hole and fix it with silicone glue to prevent air from escaping through the slots. If you have chosen a plastic box for making an air conditioner, you will have to sweat over cutting a hole: put a cooler on top and circle it with a pen, and then make a hole with a knife or scissors strictly according to the marks. It will be easier if you make marks with a thin drill on the plastic, and then start cutting along the marks.


Using long screws, screw the second cooler to the first. Instead of two small coolers, you can use one powerful one. The power of the cooler directly depends on the degree of cooling.


Remove the cover and start cutting a hole for the outlet pipe. The structure should be fixed with silicone glue.


Put on the second pipe, which will direct the air flow. It should not be fixed with glue, otherwise you will lose the ability to twist it and direct the air. You can make two holes for the pipe so that the air spreads faster around the room.


Put on the lid and make sure that the air entering the box only exits through the pipe. If small cracks are visible, they should be sealed with silicone glue.


Now the matter remains small - to get a few ice blanks from the freezer. Ice placed in 1.5 liter bottles will melt in an hour and a half after the air conditioner starts, so try to freeze water in advance. How more ice- the more powerful and cooler the air flow. The air conditioner works well without an ice blank, but then you get an analogue of a fan.


If you could not find a suitable plastic box, you can make it out of thick paper. carton box quality characteristics It is in no way inferior to plastic, however, it looks less attractive. The situation can be corrected by pasting over the old cardboard with a film. The ice that quickly evaporates inside the box will soon make the cardboard unusable, so the cardboard box will last you a maximum of one season. For convenience, insert ice blanks into a plastic bowl so as not to damage the cardboard once again.


You have the right to change the number of coolers or pipes, the shape of the box. The main thing that you get in the end is a comfortable and practical design which can cool small room and become a great alternative to a fan or an expensive air conditioner.
