We make a simple and cheap, but quite effective air conditioner with our own hands. How to turn an ordinary fan into an air conditioner DIY air conditioner from an air purifier

Every year the heat breaks new records, prices for air conditioners soar, and you always want coolness in your home without large 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 cannot be compared with 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:

• several 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;
• a piece of plumbing plastic pipe (with a diameter slightly larger than the diameter of the bottle);
• fan;
• hot melt adhesive.

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.

The principle of operation of this device: a directed air flow passes through the gap between the bottles and the walls of the pipe. 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. Use copper tubing to 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 the 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 be a great way to freshen the air in your 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 for 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 of 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. Install the stove radiator on the inside of the 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.

Wanting to save money, they use a homemade air conditioner to cool the air. Homemade devices operate on the principle of lowering the temperature of any surface when water is converted into steam.

Installation of factory and homemade air conditioner

The design of a household appliance such as an air conditioner is quite complex. The air cooling system operates by transferring 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 goes into a gaseous state, acquiring a low temperature.

The air temperature in the room and the pressure of freon, called refrigerant, are controlled by an electronic control unit, which begins to work after receiving signals from special sensors. Since the operation of an air conditioner is a complex process, making an air cooling system yourself is not easy.

Homemade air conditioners are distinguished by the fact that they are activated by 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.

Making your own air conditioner

All coolers made independently are units of two parts:

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

Ice and draft

A self-assembled air conditioner may consist of a plastic bottle filled with frozen liquid and a regular fan. This type of environmental cooler is usually placed on a table next to a running fan.

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. A container of ice is placed in this container.

If possible, it doesn’t hurt to improve your homemade air conditioner to make it work better. This means abandoning the plastic bottle and using a “cold accumulator” - a container with a special liquid used in cooler bags. The performance of such an installation for changing the microclimate is determined by the size of the vessel with pieces of ice.

A homemade air conditioner that operates thanks to ice and draft will cool the air in the room much more effectively if you assemble the installation as follows:

1. take a very large plastic vessel with a tight lid;
2. make 2 holes in the lid of the container, and the diameter of the first should match the parameters of the fan grille, 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 an “L”-shaped outlet to be formed above the cover;
4. immerse in the first hole and secure the fan well, using self-tapping screws immersed in the lid of the container;
5. Fill a tightly sealed container with bottles of crushed ice, frozen liquid or a cold accumulator.

The fan of the device, made according to the instructions, will push warm air masses through the ice container and produce cold currents exiting the corner 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 many hours.

Fan and cold water

Together with a fan, you can use not frozen, but simply chilled water to build an air conditioner, which will create a dynamic flow running through the copper radiator grille. In other words, the fan blades will draw air into the spiral of the copper tube, through which water from the water supply will flow, characterized by a stable temperature of 14–16 degrees Celsius. With this approach to designing an air conditioner, you will get an inexhaustible source of cold air.

But you will have to pay for the wasted water, 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 a compressor from the aquarium, equipped with a pipe that sucks in water and connected to a hose that runs 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 equipped with a spiral of copper tube;
4. align one edge of the copper spiral with the compressor pipe, and the other with a short hose, which occupies only a quarter of the height of the barrel;
5. attach a check valve to the end of the short hose, which blocks the movement of liquid from the barrel to the hose.

After activating the compressor, such an air conditioner comes into working condition, since the cooling spiral attached to the fan grille is filled with cold water from the bottom of the container. The liquid is given a certain direction: after running in a spiral, it will merge into the upper zone, where relatively warm water is located. The result of this organization of the movement of the liquid medium is the flow of only cooled liquid to the fan blades.

From an old refrigerator

Only men who are experienced in repair work should try to make an air conditioner from an unused refrigerator. In this case, the design of an air cooler involves the use of household appliances for freezing food, the components of which are a cooling radiator (freezer), refrigerant, compressor and condenser, which is a grille at the back of the refrigerator.

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

1. remove the doors from the household appliance that block access to both chambers;
2. Carefully, in order to avoid damage to the walls, insert a fan powered by electricity into the freezer;
3. using a drill, make several holes with a diameter of 1.5 cm in the lower area 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 the doorway, sealing the area between the body and the edges of the opening with polyethylene film).

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

From a portable refrigerator

When you decide to make an air conditioner from a portable refrigerator, in addition to the housing from a small household appliance, you must use 2 more items:

• radiator;
• submersible pump.

A homemade air cooler is constructed from a portable refrigerator in several stages:

1. a radiator of a suitable size is installed in the “box” of the device;
2. a submersible pump (taken from an aquarium or car washer) is attached to the bottom of the refrigerator body;
3. the wires are led outside the chamber;
4. a square-shaped hole is drilled in the lid of the refrigerator (from inside the body), and 2 round holes are made outside this area, which will be needed for ventilation;
5. inside the chamber, using silicone, fix the radiator;
6. the pump output and radiator inlet are connected;
7. A hose is placed at the radiator outlet, which will help make the device operate more quietly.

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

From a car radiator

If you are planning to make a cooling device from a car radiator, you will need to prepare the following parts:

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

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

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

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

The radiator used to create the air conditioner is distinguished by its plate appearance. Rubber hoses are placed on it and secured with clamps. Hollow tubes are needed to supply and discharge water. In this case, the liquid must flow from one place to another very quickly, for which the fan motor operates at high speed, providing an instant decrease in the temperature in the room.

Other options

Air conditioning can be done using a car air purifier and a standard fan, but this method is difficult and expensive.

The instructions for creating this air cooler require:

• connect the fan to the air purifier using a hose or pipe;
• make a housing for the air conditioner parts using any available materials;
• make a filter from a fine mesh mesh (fold it 4 times) and attach it to the lower area of ​​the body;
• Fill the air cleaner reservoir with water and connect the system to the electrical network.

The made device will function due to the fact that the fan moves air masses into an evaporation chamber, which contains water and cools the medium trapped in it. Outside the air conditioner, cool air will appear after passing through the holes in the mesh.

1 - body; 2 - wire mesh; 3 - air duct; 4 - holes for cooled air outlet; 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. To make this air conditioner work, you need to do the following:

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

Advantages and disadvantages of homemade air conditioners

The undoubted advantages of self-assembled air conditioners include:

• real performance, because such installations really cool the air in the room;
• the ability to assemble from scrap materials that did not require spending money.

But homemade air coolers also have a number of significant disadvantages:

• 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, since while one room is blown with cold currents, a refrigerator is working in another, freezing ice and therefore heating the air;
• significant energy consumption, which necessitates the need to replenish the supply of ice chips;
• strong humidification of the air in the room, which is caused by its passage through cold water or ice.

The air in the room will not become humid, which means it will not cause the same harm to a person as heat, if instead of ice the air conditioner is loaded with cold accumulators. Still, they are not converted into water.

All of the homemade air coolers reviewed function without problems. They are a real salvation from the heat when the situation is hopeless. True, using a home-made air conditioner causes a lot of trouble.

The heat, even if it has been expected for a long time, still hits us suddenly. The rains, of course, are boring, but the scorching heat also exhausts and reduces the ability to work. It’s good to have a split system, but few people think about it in winter or rainy spring. And in the summer, its purchase and installation turn into a hole in the family budget.

Some craftsmen decide to make a home air conditioner with their own hands, using improvised means and inexpensive materials. The idea of ​​assembling a budget homemade product is quite attractive, but before you begin to implement it, you need to evaluate the effectiveness of such a unit and study the technology of its manufacture, don’t you agree?

We invite you to familiarize yourself with the different options for constructing a home air conditioner. Among the proposed technologies, you will definitely choose the appropriate solution and be able to assemble the cooling device yourself. Step-by-step guides and photo instructions will help you implement your plans.

Before you try to make an air conditioner yourself, it would be good to understand what this device is, how it works and what effect can be expected from its operation.

An air conditioner is a technically complex device that was originally used only to cool the room in the summer. Over time, air conditioner models have improved and become more complex.

So, it makes sense to try to make your own device that has the advantages of factory air conditioners and is devoid of at least a few of their disadvantages.

What can you do with your own hands?

Please note that we do not strive to outperform factory products. It is unlikely that we will be able to achieve the same cooling power.

Our goal is to build a device that does not consume a lot of energy, is inexpensive and, in case of ineffectiveness, can be thrown into a box and trash without regret. But imagine how this homemade product will please you if you are successful!

Cardboard box tricks

The basis of this design is the same table fan and ice. But the device turns out to be quite interesting, so we decided to show it to you. The best part is that all the valuable components of this device can be easily returned to their original position without losing their functionality.

We will need:

• a corrugated cardboard box large enough to accommodate a large saucepan;
• the pan itself;
• table fan with protective grille;
• wide tape;
• gypsy needle and raw thread;
• scissors, stationery knife;
• ruler or tape measure and marker;

We need to make a box without a bottom from the corrugated cardboard of the box according to the size of our pan. The pan should fit tightly into this box, that is, match it in length and width, but the height of the box must exceed the pan by 15-20 cm.

To do this, we cut out the box with a stationery knife and cut off its bottom and lid. We roll the box according to the markings, gluing its edges and edges with tape in 2-3 layers.

The finished box (top view) should not have any holes on the side surfaces, except for a slot equipped with blinds, which is clearly visible in the photo on the left

There should be no holes in the walls of the box. We cut out a square box lid from the remnants of corrugated cardboard. It's better to make it two-layer.

In its center we mark a circle, the diameter of which should be 2-2.5 cm greater than the span of the fan impeller, so that its blades fit freely into the cut out round hole and do not touch the edges during their rotation. We secure the lid in its place with tape.

At the level of the upper edge of the pan placed in the box, we cut out a rectangle 3.5-4 cm high in its wall. The length of this “embrasure” can be different, but it should not reach 4 cm to each of the side edges of the box in order for the structure to preserve rigidity.

Cooled air will flow out from this cutout. And to control the flow, you need to build blinds for it.

To do this, we cut out two strips from corrugated cardboard, the length of which is 4-5 mm less than the cutout, and the width is 5 mm greater. We connect these strips together at a distance using a gypsy needle and harsh threads. We make punctures in the top strip at a distance of 7-8 mm from the edge, and in the bottom - 12-15 mm.

We insert the blinds into the opening and fix each strip at three points. We do not tighten the threads, but secure them with knots.

Try moving the blinds with your finger. The structure must move freely and not crumble when moving. Now you can start assembling the device. Place a rug or old cloth in several layers under the pan to make the appliance work more quietly. The stability of the pan should not be affected.

On the left, through the round hole in the lid of the box, the ice is clearly visible, which is located on the fan grille covering a large pan, and on the right, the device is photographed in operation

Place the pan and cover it with the front protective grille of the fan with the concave side up. Place pieces of pre-prepared ice on the grid. It is better to prepare it in plastic glasses, because large pieces melt more slowly than small ones. We cover the structure with a box.

Insert the fan into the hole in the top cover with the blades down. You can turn it on and check the quality of work.

Melted ice turns into water, which must be poured out of the pan in time so that it does not leak out and soak the box. Otherwise, the fan may fall into water, causing a short circuit.

You can get a good look at the entire process of constructing this air conditioner by watching the video that we placed in a special block at the bottom of this article.

Plastic bottles and plywood sheet

This wonderful design does not require electricity or even frozen water. The only thing needed for it to work is a draft.

The principle of operation of the device is easier to explain with an example. Open your mouth wide and exhale sharply onto your hand. The skin will feel warm. Now you need to stretch your lips with a tube and blow again with the same force as the first time.

This time the air jet cools your skin. If air passes through a narrow channel, then when it expands instantly, it cools.

Let's prepare a sheet of cardboard, but better than plywood. It must correspond to the size of the window opening that we want to close with this design. We'll also stock up on plastic bottles. From each of them we will need only the upper third with a cork. We'll cut it off.

By the way, the plugs need to be removed, but not thrown away. They will be useful to us for securing bottles to the surface of the sheet.

We will need so many bottles so that they cover the entire surface of the sheet, but do not touch each other. To measure the holes for them, you can use a long pencil, which is used to mark the center of the cut through the neck.

To drill a hole for a standard bottle, you need a crown with a diameter of 18 mm. Using a drill, drill out all the holes one by one.

The cut-off tops of bottles without corks are inserted into the holes and secured with their own corks, the tops of which have been cut off. This produces rings with internal threads that perfectly hold bottle segments.

All that remains is to install the finished air conditioner in the window opening with the funnels facing outwards. Experts guarantee that the temperature in the room will drop by five degrees.

Adding a fan to the circuit

One of the obvious disadvantages of the previous device is that it deprives users of natural light in the room. Additionally, drafts may be a problem in your area. Then use this idea.

To implement it, prepare:

• sustainable household fan;
• six plastic bottles;
• a sheet of thin plastic or thick cardboard - whatever you find;
• plastic clamps;
• stationery knife;
• silicone hot glue.

The operating principle of this cooler is the same as the previous model. Only you don’t need to install it in a window opening, and it can work in any room: it’s portable.

The following photo instructions will introduce you to the manufacturing process in great detail:

Image gallery

Let’s take six pieces of 1.5 liter plastic bottles from the same production. It is advisable, but not at all necessary, to choose containers of the same color

Focusing on the top edge of the label, carefully cut off everything that is below it. We do this with all bottles.

Almost all home-made air conditioners use the principle of cooling the surface by evaporating water. If you blow on a wet fabric, then as it evaporates, it will cool the surface of the material, and it will, accordingly, cool the air located around at a very short distance. This principle formed the basis of the simplest climate control device, like a wet towel on a fan body. To automate the process somewhat, you can dip part of the towel into a container of water; it will be absorbed by the fabric and evaporate under the influence of the air flow.

If after the theory you still have a question about how to make an air conditioner with your own hands, then pay attention to several simple and cheap “recipes”.

Fan and plastic bottles

This is the same air conditioner, but instead of a towel, frozen water bottles suspended from the fan housing are used. Make sure that there is a gap between the cooler sections for free passage of air.

The main advantage of this manufactured air conditioner is its low cost and reusability. Frozen bottled water changed its state of aggregation and turned into water, took a new portion out of the freezer, and put this one to freeze. The disadvantage of this design is the problem with draining the condensation that inevitably appears on the surface of bottles with ice.

If the proposed schemes do not suit you, then you can always

You can find out what's new in modern air conditioner models in the article.

Pipe, water and fan

This is another variation of a self-made air conditioner on the theme of using frozen water and its cooling properties. Take a piece of plumbing plastic pipe with a diameter slightly larger than the diameter of a plastic liter bottle. A fan of suitable diameter is mounted at one end using hot-melt adhesive. Several plastic bottles with frozen liquid are placed inside the pipe.

A directed air flow passes through a small gap between the bottles (cooler) and the walls of the pipe. Prolonged contact of air with cold objects quite significantly lowers its temperature, after which the structure remains directed to the cooled room. The issue remains with the condensate drainage, but this can be solved by making several small holes in the bottom of the pipe.

Expert opinion

Ask a question to an expert

Do not direct a cold air stream at a person, especially one who is hot in the summer heat. This is not safe for your health!

Container, ice and fan

This is a small but effective air conditioner, made by yourself on the same principle as previous models. Its main advantage is the direction of action, compactness and ease of use.

To do this you will need:

• Plastic container 1.5-2 liters.
• Stationery knife.
• Cooler from a computer power supply.
• Corrugated plastic siphon.
• Glue gun.

Take a container for storing food or non-food products. It would be better if it were flatter in shape. A hole is made in the cover, slightly smaller than the intended fan from the computer power supply. It is glued into the lid using a glue gun so that it draws air into the container. A second hole is cut at the other end of the lid, of a smaller diameter, for a corrugated plumbing siphon.

Ice is poured into the container. The air, drawn in by the fan, is cooled in the container and exits through the corrugation.

1. It is best to use a plastic container as a container.
2. You will also need a plastic plumbing corrugation used for draining
3. Fan and 15V power supply
4. Ultrasonic emitter. In Chinese online stores it is called Mist Maker or fog maker, and costs about 4-5 USD.

We begin assembling the ultrasonic humidifier with our own hands.

1 step. We cut two holes in the cover: one for the fan mount,

second - corrugations

Step 2. View of the finished cover

Step 3. We connect the fan to the power supply. The red wire is a plus, so we insert it into the socket, h black - minus, connect to the outside of the plug. Afterwards we isolate all connections.

Making an air conditioner from an old refrigerator

This is practically a real air conditioner, based on the transfer of heat by freon from the evaporator to the condenser. To do this you will need:

• Jigsaw with metal file.
• Two fans
• Polyurethane foam for sealing.

You can make your own air conditioner from a refrigerator by installing a fan in the freezer door that blows air inside. To allow cooled air to escape, make a second hole in the freezer door, into which you need to insert a plastic pipe. Carefully seal the cracks using polyurethane foam.

For better heat removal, you need to install a second fan directed at the condenser. Now you should apply voltage to the refrigerator and fans and you can cool the country house.

Adding on topic

Note!

Which air cooling method from those provided will you choose?

When it's hot outside, only the coolness of the air conditioner helps. But not every apartment has it. And not everyone is ready to spend money on it. Moreover, the inquisitive minds of the Kulibins, paired with golden hands in empty pockets, are able to make an analogue of a modern air conditioner practically for free. On the Internet we found two proven and relatively simple designs for homemade “kondeya”.

It is impossible to make a real air conditioner from improvised means. The conversation will focus on homemade air coolers, which can be considered as a temporary solution and a way to get rid of the heat in the room.

The simplest “air conditioner” is a hybrid of a fan and an ice chest. Quite an effective solution with almost zero cost. To assemble it you will not need many components: a plastic or foam box, two ventilation elbows, a simple vent type fan.

The box can be made independently from sheets of polystyrene foam or polystyrene foam. One hole is cut in the cover for the fan and one or two more on the sides (possibly in the end walls of the box) for ventilation units. Their size should ensure a tight connection. Look how simple it is:

After assembly, coolant must be placed in the cooler box. These can be large pieces of ice, bottles of frozen water or special cold accumulators. The latter work longer due to the fact that they are filled with a special gel. After this, you can only turn on the fan and enjoy the coolness.

A more advanced and efficient “model” will require higher costs for components. To assemble it you will need a floor fan - the larger the propeller, the better. You will also need a copper tube, 2 flexible plastic hoses, clamps, an aquarium pump, and a sealed container.

Photo: takprosto.cc

The assembly sequence is as follows. We twist the copper tube in turns, forming a spiral from the outer edge of the fan grille to the center. It is important that there are always small gaps between the turns of the spiral to allow air to pass through. The tube is attached with plastic clips to the metal grille of the fan.

We place a small pump (can be from an aquarium) in a prepared container (plastic box, bucket). We connect one plastic tube to the pump, and simply lower the second tube into our container. Pour water into the container and add ice.

Turn on the fan and pump. Such a device can reduce the room temperature by 5-10 degrees.
