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.
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:
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.
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 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
All self-made coolers are two-part units:
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:
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.
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:
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.
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:
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.
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:
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:
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.
Thinking of making a cooling device from car radiator, you will need to prepare the following details:
To assemble an air cooler from these elements, you need to perform certain tasks:
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.
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:
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:
The undoubted advantages of air conditioners assembled independently include:
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 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 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.
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:
Action plan:
The water needs to be changed periodically. You can make two sets at once, cooling them alternately.
Manufacturing:
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.
You will need:
Mounting scheme:
Such a unit is able to cool a medium-sized room. Can be costly due to the large amount of water supplied.
Necessary materials:
How to make a homemade air conditioner, assembly design:
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.

Device instruction:
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.
Necessary:
Manufacturing process:
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).
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:
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.
