How to make a high-quality air conditioner with your own hands. How to make an air conditioner from a fan? How to make an air conditioner from a regular fan at home? Air conditioner from improvised means

Every year, the heat breaks new records, prices for air conditioners soar, and you always want coolness in your home without much effort. financial costs. We offer you several ways to escape the summer heat, for which you will only need available means and ingenuity. We will tell you how to make air conditioning at home.

Important! All home-made air conditioners use the principle of cooling the surface by evaporating water. Of course, a homemade air conditioner is not comparable to a split system, but it can lower the temperature in the room by several degrees. Let's look at some examples of making heat remedies at home.

A remedy for the heat from our ancestors

Back in the days of no cooling systems, our ancestors used a wet towel. They wrapped it around, for example, a bottle and placed it in a through place, and during the process of evaporation of water, cooling occurred. This principle formed the basis of the simplest climate control device - a wet towel on the fan body. If the process is automated, then part of the towel can be dipped in a container of water; it will be absorbed by the fabric and evaporate under the influence of the air flow.

The most primitive home air conditioner

If you don't want to spend a lot of time assembling a complex device, but still want to make an air conditioner at home with your own hands, you will definitely like this method.

To create a cooling system you will need:

• some plastic bottles with frozen water;
• fan;
• wire for fastening or bottle tray.

Proceed this way:

1. Freeze bottled water.
2. Place the containers a couple of centimeters apart from each other, placing them on a tray or attaching them directly to the fan.
3. Turn on the fan.

Advantages of a homemade device:

• cheapness;
• reusable.

Disadvantages of this design:

• problem with drainage of condensate bottles appearing on surfaces;
• frequent need to replace bottles with containers of frozen water.

Pipe, water and fan

This is another option on how to make air conditioning at home using frozen water and its cooling properties, which is also not difficult.

To make the device you will need:

• several plastic bottles with frozen liquid;
• piece of plumbing plastic pipe(with a diameter slightly larger than the diameter of the bottle);
• fan;
• Hot melt glue.

Manufacturing instructions:

1. Place several plastic bottles of frozen water inside the pipe.
2. Attach the fan to one end of the plastic pipe using hot glue.
3. Turn on the fan.

Operating principle of this device: A directed air flow passes through the gap between the bottles and the pipe walls. This contact of air with cold objects greatly reduces its temperature.

Disadvantage: there is no provision for condensate drainage, but if you make a few holes at the bottom of the pipe, this will not be a problem.

Important! Do not point the structure at a person, especially in the summer heat, as this is hazardous to health.

Hose, copper tube

If you set out to make a more advanced air conditioner with your own hands, adopt this method.

This design uses:

• garden hose (preferably made of rubber);
• thin copper tube;
• fan.

Manufacturing:

1. Using copper tubing, form a radiator over the entire surface of the radiator grille (leave gaps for air flow).
2. Secure the formed radiator.
3. Connect one side of the tube to a cold water tap.
4. Direct the other end down the drain.
5. Turn on the cold water tap.
6. Connect the fan to electrical network.

Schemes of portable (portable) air conditioners

Such climate control devices will be a real salvation for people who are tied to their workplace: office workers, gamers.

Container, ice and cooler

The principle of this small air conditioner is the same as that of previous models. Its main advantage is its compactness, ease of use and direction of action.

To make your own air conditioner, you will need:

• plastic container 1.5-2 liters (for storing food and non-food products.);
• cooler (from the computer power supply);
• corrugated plastic siphon;
• stationery knife;
• glue gun

Step-by-step assembly instructions:

1. Make a hole in the lid of the container - slightly smaller than the fan.
2. Using a glue gun, stick the cooler into the lid so that it draws air into the container.
3. Make a hole in the other end of the lid using a utility knife (this is the hole for the corrugated siphon).
4. Cut 25-35 cm from the corrugated sanitary siphon.
5. Glue this section into the lid using a gun.
6. Fill the container with ice.
7. Close the lid.
8. Connect the fan to the power supply.

Your portable air conditioner is ready. Rotate the siphon section and direct cold air to any point in the room.

Air conditioner from an old refrigerator

If you have an old refrigeration unit, it will serve as a great way to freshen the air in the room. In practice, this is a real air conditioner. The principle of operation is based on the transfer of heat by freon from the evaporator to the condenser.

To make the device you will need:

• 2 fans;
• plastic pipe;
• jigsaw (with a metal file);
• polyurethane foam.

Step-by-step manufacturing instructions:

1. Drill a hole for the fan in the door.
2. Install a fan in the freezer door to blow air inside.
3. Make a second hole to allow cooled air to escape.
4. Insert a plastic pipe into this hole.
5. Carefully seal the cracks using polyurethane foam.
6. Install a second fan directed at the condenser for better heat removal.
7. Plug in the refrigerator and fans and you can cool the room.

Important! You can make more than just an air conditioner from an old refrigerator. Want to know how else you can use it? We covered this topic in our review.

Cooling device from a car radiator

To make your own air conditioner from a car radiator, you will need:

• radiator (preferably from domestic cars);
• fan (can be purchased together with the radiator at an auto parts store);
• plastic clamps;
• rubber hose;
• sealant;
• case from a computer power supply;
• terry towel (as a tray).

Manufacturing instructions:

1. Mount a radiator on the back of the case.
2. Build a fan into the front of the case.
3. The air flow should move from the radiator to the fan.
4. Install rubber hoses on the pipes extending from the radiator and secure them with clamps.
5. Water is supplied through one hose. Connect it to a cold water tap. The other hose serves as a means of draining water.
6. Place this entire structure on a towel.

Important! The main thing in this system is the speed at which water will pass through the radiator and the speed of the fan motor. The speed of cooling the room depends on all this.

The advantage of this device is that there is no condensation.

Flaws:

• the radiator must be connected to the electrical network via a 12 V adapter, which must be purchased separately, or used from an old computer power supply;
• labor-intensive manufacturing method;
• If the apartment is equipped with water meters, then such an air conditioner will be quite expensive.

How to make air conditioning in a car?

To make a car version of the air conditioner you will need:

• a plastic container (a container from a cooler bag is best);
• interior radiator from the stove;
• small submersible pump (aquarium or machine washer);
• a pair of fans;
• connecting tubes.

In a car, the device can only work from the cigarette lighter, so if you do not have a car charger for your phone, you will need to purchase one.

To make an air conditioner for your car with your own hands, follow these instructions:

1. Place a pump at the bottom of the container.
2. Route the wires from the pump outside.
3. Make a couple of holes in the lid of the container for fans.
4. Secure the fans.
5. WITH inside Install the stove radiator cover using silicone.
6. Combine the wires from the fans, pump, and charger.
7. Connect the pump to the radiator using connecting pipes.
8. Place ice inside the container.
9. The device is ready for use.

Important! A car air conditioner can provide comfortable conditions in the cabin for up to 5 hours. To get rid of excess noise when the air conditioner is operating, attach a hose to the radiator outlet.

Already with the onset of the first hot summer days, many people are thinking about purchasing an air conditioner. Prices for these units usually rise during the season, and in both spring and winter, air conditioners are no different. In addition, having bought a treasured device for 10-20 thousand rubles, get ready to shell out another 2-5 thousand for its installation. The situation, so to speak, is difficult - most citizens just sigh and suffer from the heat. Others take out loans, paying huge interest rates. But there are also enterprising people who have figured out how to make an air conditioner from a fan and other improvised means. We have collected their ideas in this article.

Method one

How to make an air conditioner yourself with only a fan? Very simple!

1. Take a more powerful fan and attach it to its iron protective grille, wind a hose or thin copper tube in a circle. The more circles you make on the grid, the stronger the effect will be, just remember to leave a small distance between the circles.

2. Insert one free end of the hose into a tap with cold water, and lower the other into a basin or bathtub.

3. Turn on the water (the pressure should be good) and the fan.

4. Enjoy the cooling effect.

So you have learned how to make an air conditioner from a fan. Yes, it may not be possible to cool the room very much, but if the room is small, the refreshing effect will be guaranteed!

How to make your own air conditioner? Method two

If the room is small and the bathroom with a tap is very far away, this simple method will do. So, how to make air conditioner from a fan and ordinary plastic bottles?

1. Fill plastic bottles with water and leave them in the freezer overnight.

2. Place the fan so that there is some flat surface (for example, a table) close to its blades.

3. In front of the turned on fan, place the bottles in a row with small gaps.

4. Change bottles if the water in them is already half melted. To make the melting slower, you can add a little table salt to the water before freezing.

How to make an air conditioner from a fan in a car radiator

This method is the most difficult, but also the most effective.

1. Take a radiator from a car equipped with an electric fan.

2. Connect a pair of rubber hoses of the appropriate diameter to it. Water will flow in through one, and out through the other.

3. Place the device on a flat surface.

4. Connect the radiator to the outlet via (12 Volts).

5. Run cold water through the hose (the pressure should be low).

6. Enjoy the desired coolness.

We told you how to make an air conditioner from a fan. And if this household appliance not at home? Even in this case, you can create coolness.

Let's describe the last way to make an air conditioner yourself, without even having a regular fan.

1. Count the number of windows in the apartment - how many pieces of chintz or gauze you will need.

2. Create a draft in the room - only then will there be an effect. Ideal if the weather is windy and there is air movement in the room.

3. Wet pieces of cloth or gauze in cold water, squeeze slightly so that the water does not flow.

4. Hang them on doorways and windows.

5. Wet as it dries.

This is the so-called country air conditioner, it is especially good at night - the fabric dries more slowly.

Ecology of consumption. Estate: B summer period 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 using improvised means will come to the rescue.

In the summer, the issue of air conditioning becomes 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 using improvised means will come to the rescue. Such a device will fit especially well into the interior of a dacha or country house, but it can also be successfully used in an apartment. It is better to start making an air conditioner in advance, before the hot days arrive. Since it is unknown how long it will take for someone who has no experience in such matters.

WHAT ARE THERE ARE HOMEMADE AIR CONDITIONERS?

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

Indeed, both devices serve practically the same purpose - producing cold and cooling something. The refrigerator cools the products, the use of the air conditioner is wider; it cools the room, the people who are there, as well as everything that falls within its radius of action.

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

In order to make a homemade air conditioner from a refrigerator, you need to find an old unnecessary freezer, which, however, is in working condition. If you don’t have one, you can purchase someone else’s by finding it in an ad.

To work, you will need a household jigsaw. It can be used to make shaped cuts on metal surfaces. A corrugated pipe is suitable as a drainage pipe. It weighs less than pipes made from other materials. You will need insulating material and insulation, as well as polyurethane foam. For cooling you need fans, it is better to have two of them.

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

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

ALTERNATIVE METHOD OF CREATION

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

After this, two hoses are connected to the device. One of them is connected to the sink, and the other to the water supply system. Fastening is carried out using homemade stands. Under the finished air conditioner, you must place a tray to collect condensate, which will need to be drained regularly.

The equipment works this way. The 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 well. Regular tap water, unfortunately, will not give the effect we need and will cool the room slightly.

OTHER METHODS OF MANUFACTURING AIR CONDITIONER

What else can an air conditioner be made from? There are even easier and cheaper ways to assemble an air conditioner from improvised materials. 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 the fan with a small gap. The water must be pre-cooled in the freezer. When the water heats up, it will have to be replaced with a new one.

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

Another option also applies to simple designs, but is more original and effective. Take a small diameter copper tube and a rubber hose. The tube will serve as an improvised radiator. It is twisted in the form of a spiral. The hose is needed to connect our “radiator” to a tap with running cold water. The tube must be copper, because copper bends better than other materials and has high thermal conductivity. To secure the hose you need clamps and sealant.

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

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

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

• Fan power;
• Radiator size;
• 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 fixtures for mounting the fan. The cost of such an air conditioner will not exceed 3-4 thousand rubles.

MORE COMPLEX AIR CONDITIONING DEVICE

Making such a device is not so easy, and may even require instructions. But it will be able to cool a room of up to 30 square meters. m. In summer, it is convenient to install it in a window, where it will simultaneously not only cool the air, but also promote 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.

The air passes through the grille and enters the oil filter, where it is freed from dirt and dust. Next, it enters the humidifier, and then exits into the room through the grille.

You can reduce the noise from operating equipment if you connect an electric lamp or other device in series to the fan circuit. Its power should be such as to minimize the noise effect. The switched on 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 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, which contains water. The wicks serve to allow water to flow through them into the inside of the device, where it evaporates and humidifies the air, which then enters the room. Excess water remains in a special tray.

By the way, there is no need to empty the tray. After all, the water from it rises again through the same wicks, evaporates and humidifies the air again. The air conditioner has an oil filter that looks like a wooden frame with a wire mesh. Its cell size is very small, about 1x1 mm. The mesh is lubricated with Vaseline oil. After a while, when the filter becomes dirty (usually this happens once or twice a month), it should be washed with hot water.

ADVANTAGES OF USING A DIY AIR CONDITIONING SYSTEM

So, we looked at how you can make air conditioning at home. What advantages can be derived from its use? The main advantages of the homemade devices presented above are:

1. Saving money.
2. Great for use in the garden and country house, where it is impractical to create a professional system. People come to their dacha mainly in the summer, and in the 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 make such a useful thing as an air conditioner with your own hands.
4. Gaining new knowledge and experience in the field of converting one thing into another.
5. There is no need for expensive equipment care and maintenance products.
6. Comfort and vitality in the room due to air cooling in summer.
7. There is no need to periodically purchase and change filters, since they are absent in almost all of the devices reviewed.

As it turned out, making a homemade air conditioner for an apartment is not so difficult. And anyone can cope with this. You just need to understand the principle by which a regular household air conditioner works and start acting. published

During hot weather, we all face the problem of dry air inside heated buildings, especially such negative impact felt in multi-storey 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 scrap materials with your own hands. This article will tell you exactly how.

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

Our ancestors often used homemade devices to cool the room, when there was no trace of such a word - climate system - in the lexicon. To do this, a thick canvas fabric was hung on the transom of a window or window, and the other end was lowered into a basin of water. Hot air from the street dried the canvas and a cooled and humid stream entered the room. Many people still make such an original and simple homemade 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 using improvised materials, you will need:

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

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

Any user can build such a simple household homemade air conditioner at home; 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 disadvantages: it is necessary periodically add cold water.

Plastic containers+water

Another pretty one original version with the participation of a household fan, and for its manufacture the following components are required:

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

For the best effect, place bottles of water in the freezer and freeze, but there is one trick - to make the ice melt 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 supplies cooled air to the desired location. We change bottles periodically. If there is no space to place them on a plane, then you can fix them on the back of the household appliance. This air conditioner made from 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 air flow, and secured to the device limiter with clamps. One end is connected to the tap, and the other to the drain. The cooling process is also simple - water circulates through the tube and cools it, the air flow passing through homemade device, cools down.

The disadvantage of the system is that it can only be installed in the kitchen, which results in significant water consumption.

Ice and cooler

You can make a mini-air conditioner with your own hands 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 along the entire perimeter to suck in air, carefully drill the disk in several places. At a distance of 1/3 from the bottom, screw in three self-tapping screws that will hold the disk in the desired position. Ice is placed on the CD, the entire structure is closed with a lid on which the cooler is rigidly mounted - it will draw out cooled air from the inside. We connect the old USB cable to the cooler, and insert the other end into the connector of the system unit or laptop.

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

Unique device made from bottles

As everyone knows, Africa is the hottest continent on our planet; in some regions there is intense heat almost all year round and there is no electricity. Craftsmen from Bangladesh came up with a very original air conditioner made from plastic bottles, based on a physical law: the gas’s own temperature decreases when passing through a sharp contraction and maximum expansion subsequently.

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

The unique device is very simple to make - we provide an algorithm for all actions.

1. We cut out a rectangle from plywood or fiberboard that matches the window opening.
2. We measure how many bottles fit on it, installed closely. It is better to select a container designed for 2 liters.
3. We drill pre-designated 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 secure them. If there are gaps, then fill them with silicone sealant.
5. We fix the made air conditioner in the window with the bottles facing out.

This is probably the most environmentally friendly device in the world - what else do you need in the heat at the dacha.

Radiator+fan

There is no limit to the imagination of home craftsmen - they try to update almost any old equipment and give it a second life: for example, a miracle air conditioner made with their own hands from an old car aluminum radiator.

The 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, and water is supplied and drained through specially routed tubes. For ease of carrying, handles are attached to the body. Gifted craftsmen install the power supply with different voltages, so that there are several operating modes, and control will be carried out by a built-in switch.

Durable rubber hoses are secured to the tubes using clamps; one is used to supply water, and the other is used to drain. The advantage of such a miniature split system, made by yourself, is high speed of water passage through the main device and fast rotation of the fan. At the same time, condensation does not appear on the radiator, constructed from aluminum plates.

Unusual use of a freezer

From an old refrigerator, with some skill and a flight of imagination, some homeowners make an air conditioner that installed in a window opening or a special niche with access to the street. The chamber intended for freezing food is inserted in such a way that the back part is completely outside, since there is a radiator located there, 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.

You can make an air conditioner from a refrigerator using an old one. portable version of a household product.

1. We take the case from a mobile version of the refrigerator, which has not been working for a long time, but keeps a good seal, remove the lid, and install two coolers from the computer on it. To do this, outline the size of each, then drill round holes using a drill and a mechanical jigsaw.
2. We put the coolers in place and seal all the cracks with sealant.
3. We put ice inside the chamber - you can pre-freeze the required amount in a plastic container suitable in size to the internal volume of the old device.
4. We close the lid tightly and turn on the fans using a specially purchased device or connect them to the PC. The ice takes quite a long time to melt, and a home-made air conditioner from an old mobile refrigerator 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 possible without any special technical skills. All suggested 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 at the dacha, and for car enthusiasts who still have old radiator from the stove An original air conditioner like this is suitable, the manufacturing method of which is shown in the video:

Modern air conditioners have a significant cost and are not available to everyone, which is why an alternative has appeared - a homemade air conditioner. As practice shows, such units, although far from ideal, can save you from the heat for some time.

To make an air conditioner at home, first let’s look at how a regular household cooler works. It consists of two heat exchangers, a compressor, a throttling device and two fans.

A heat exchanger located inside the room takes heat from the air flow passing through it, as a result of which the latter enters the room cooled. The refrigerant transfers the removed heat through the tubes to the second radiator, which transfers it to the environment.

The diagram below shows the operating principle of the air conditioner.

Air conditioner device

The efficiency of domestic and industrial air conditioners is based on the processes of vaporization and condensation, accompanied by the exchange large quantity warmth.

To understand this, just remember the school physics course. The amount of energy spent on heating or cooling a substance is characterized by its specific heat capacity. But there are also additional heat costs that go into the transition of a substance from one state of aggregation to another, and these costs are very significant. The liquid is heated to a boil using a certain amount of heat, after which it turns into steam, which requires additional energy, called the specific heat of vaporization. As the steam cools, it condenses, releasing the same energy back.

A home air conditioner takes heat from the room air to boil the refrigerant. The compressor, which creates pressure in a closed system, moves it through the throttle to the second heat exchanger, where the refrigerant condenses under the influence of the flow of outside air, to which it releases thermal energy.

Example: To heat 1 liter of water by 1 ºС, 4.187 kJ of heat is required, and to evaporate the same amount it takes as much as 2256 kJ. This is where the 300% efficiency of refrigeration units comes from.

Types of homemade air conditioners

Homemade air conditioners are simple, but work on different principles. Conventionally, they can be divided into the following groups:

• home air conditioner from a used refrigerator;
• cooler operating on running water;
• an air conditioner that uses ice frozen in another unit.

Before you make an air conditioner from improvised means, you need to choose for yourself the most convenient of the 3 proposed options, and for this we will consider their principle of operation. The first unit on the list is the only one that operates according to the traditional effective “evaporation-condensation” scheme. And this is because for its manufacture all the filling is taken from an old refrigerator: a compressor, an external heat exchanger - a condenser and a freezer, which is an evaporator.

You can make such an air conditioner yourself. An evaporator is placed in the cooled room, having previously installed an axial household fan on its rear side. A freon tube is passed through the wall and connected to a condenser and compressor mounted in an adjacent room. If necessary, you can take 2 sets of heat exchange equipment, as shown in the video.

Disadvantages of making an air conditioner from an old refrigerator:

1. Differences in design will also affect operating efficiency, since the refrigerator was originally designed to maintain a low temperature in a small enclosed space.
2. Due to the above, the compressor of this device will never stop, and in this mode it will not last long. Unless the cooling system will be additionally automated using air temperature sensors and a power control unit.

Air conditioners using cold water and ice

Taking a regular car radiator and a household fan, you can assemble a water-based air conditioner. Adapters will have to be made to its pipes to connect hoses with running water, and the fan will have to be fixed at the back.

You just need to organize its power supply with a voltage of 12 V.

Leaking through the radiator cold water, taking away heat from the air pumped by the fan. Such a device can hardly be called an air conditioner; rather, it is a simple air cooler, since the intensity of air cooling directly depends on the water temperature. These are used in industrial ventilation; only the feed water is cooled by special installations - chillers. At home, there is nothing to cool the water with, you will have to take what you have from the tap. Regarding this option, it should be noted that the idea is not bad, weak point There is only one thing, but it is significant - the inability to provide low-temperature feed water. Clear instructions How to make an air conditioner with your own hands using water is presented in the video.

The third option is the simplest air conditioner that cools the air using ready ice. 2 holes are made in a tightly closed plastic container: one for the fan, the second for the air outlet pipe. The container is filled with ice, closed, and a fan forces the heated air mixture from the room inside. The latter quickly cools, washing the ice, and exits back through the pipe. Air conditioners for cars are also made in a similar way. One additional recommendation: It is better to cover the inside of the container with sheet polystyrene foam.

Some craftsmen adapt a household cooler to a car air conditioner, since installing a standard one will be more expensive. The operation is quite labor-intensive and difficult, but it provides some advantage: the operation of the refrigeration unit does not depend on the engine.
