Do-it-yourself air conditioning - cheap and cool

In hot weather, a person seeks a stream of cool fresh air, especially indoors when work is intense. Fan does not save, it just drives the same hot air back and forth. And air conditioning would help, but you can’t put them in all corners, it’s expensive. And in this case, ingenuity helps out: after all, you can make an air conditioner with your own hands. There are many options, only skillful hands are needed.

Operating principles of a traditional air conditioner

In full accordance with the laws of physics, any liquid absorbs heat during evaporation. In a kettle, water turns into steam, because it takes heat from a gas stove, in a puddle, water heats up from sun and evaporates, a wet sheet on a rope gives off its own heat, the sheet dries and cools down. So in the refrigerator, and in the household air conditioner there is a certain container - an evaporator filled with a special liquid - a refrigerant.

The refrigerant, evaporating, turns into cold vapor, the prescribed temperature passes through the pipeline (coil) engineers way, on the way it cools everything that gets in the way, it heats up itself and turns back into liquid. And so on ad infinitum. If this happens in the air conditioner, then the fan drives the room air through the coil, the air is cooled and enters the room in this form. And the people in the room become cool and pleasant.

Homemade air conditioner from a car radiator

Not without reason there is a saying "The need for inventions is cunning!". If there is no money for branded split system, you will have to provide comfort with your own hands.

What is required for work

Everything you need for work can be found in the garages of car enthusiast friends or in the nearest auto shops. Any radiator is suitable, but preferably larger than that of the Oka. Automation is not needed. You will also need a car radiator fan with a nominal voltage of 12 volts for the electric motor. Can be taken from GAZ, VAZ, AZLK, IZH, ZAZ or ZIL cars (power 110 W).

For the fan, you will need a casing and some fasteners, and for a complete set, you will also need reinforced rubber tubes, clamp set (4 pieces), matched to the diameters of the pipes, inexpensive sealant, insulating tape, connector for fan voltage connections, 230W computer power supply with 12V DC output Volt.

Device assembly

Rubber tubes connect the radiator to the cold water supply and to the drain into the sewer. Water is supplied from below, return (outgoing water) is connected from above. A single design is assembled from a radiator and a fan and installed in a convenient place. Such a device can serve one small room.

How to make an air conditioner from an old refrigerator

In order to make an air conditioner, it is not necessary to disassemble the car, even the old one. You can turn an old refrigerator into an air conditioner. But something in it all the same should work. Such an alteration will bring a lot of benefits to the owner of the former refrigerator. First, he will get air conditioning. Not very beautiful, but working and almost free. No need to go and buy a new one and spend a lot of money. For such an air conditioner, you do not need to regularly buy filters to replace them. And how nice it will be to enjoy the fruits of your labor!

Tools and materials

First of all, you will need an old refrigerator, which they did not have time to scrap, and two small fans. Of the tools you need a household electric jigsaw. You will also need a corrugated sewer pipe, polyurethane foam or a special insulation.

A hole is made in the refrigerator case, and a corrugated pipe is inserted into it tightly without slots. All cracks are covered with mounting foam. The pipe comes out of the refrigerator body and leads to where cold air is needed.

The process of converting a refrigerator into an air conditioner

Not everyone believes in the feasibility of this idea, but it does not contradict the laws of nature. So, you need to be smart and mobilize all your ability to work with various tools.

If the ceiling height is below 3m, then for cooling every 10m² 1 kW of power is required. Simple calculations show that fridge with a volume of 350 liters is able to maintain comfortable conditions in a room of 10 m².

Alteration work begins with the fact that in the refrigerator door you need to cut a small round hole with a diameter of no more than 10–15 cm. All rubber seal must be removed from the refrigerator door to allow free access of outside air. Inserted into the window cut out in the door corrugated pipe. The junction of the pipe and the edges of the window are carefully sealed mounting foam. Now it remains to install two fans inside the case: one of them will blow the compressor, and the second will drive cooled air through the corrugated pipe.

Homemade air conditioner from a floor fan and plastic bottles

A good floor fan can “serve” several bottles of ice at once.

What do you need to work

Need a fan to work, empty plastic bottles and a freezer to produce enough ice.

Manufacturing of the cooling device

An effective air conditioner still requires the use of a fan. You can use a small desktop, you can use a large floor. They have the same principle of air cooling, but the flow of cooled air will be different.

The idea of ​​air cooling in all variants is the same, the dimensions of the unit and design solutions vary. The essence of the idea is that through the installed group of plastic bottles filled with ice, the fan drives the air. The more bottles and the larger their volume, the greater the mass of cooling ice and the colder the air passing through the "ice system" will be. Only the bottles do not need to be placed close to each other, it is necessary to maintain gaps of 2-3 cm.

A small table fan placed in front of a group of ice-filled 1.5-liter bottles will save one person from the heat. A large floor fan can blow a group of several 5 liter bottles. The flow of cooled air will be more powerful. The main thing is to freeze more ice in advance and refresh the contents of the bottles. On the grate of the floor fan, ice bottles can be fixed, but in such a way that they can be easily changed.

When working with such a cooler, it is necessary to take into account one thermal moment. Condensation will form on the cold surface of the bottles, which will drain to the floor. Therefore, it is necessary to provide measures against flooding the room, for example, put a thick rag and wring it out from time to time.

Mini air conditioner from a table fan and a cardboard box

This is an option for the case when there is no means other than an empty pot and a large cardboard box. Yes, you still need to have a sense of humor, because the product will be very funny.

Materials and tools

You need an empty pan with a volume of 2-3 or 5 liters - the more, the better. And the fan is desirable with a diameter equal to the diameter of the pan. You will also need a sharp knife and stationery (or similar) glue. And dexterous hands.

Description of the operations performed

The box is carefully glued along all the folds (for example, with adhesive tape) so that it does not fall apart during work. Before that, a round window is cut out in the upper plane, equal in diameter to the pan. The pan itself should be installed in the box so that it slightly comes out of this window. And there should not be any gaps, they must be covered up. A rectangular horizontal window about 3 x 10 cm in size is cut out in one of the side faces of the box. Here you need to glue a pipe of approximately the same size.

The pan is covered with a protective grill from the fan, lumpy ice is poured into the grill. A fan is attached to the top. The conditioner from the pot with the box is ready. Melting ice will flow into the pan. Ribbons are glued to the nozzle to monitor the operation of the unit and control the direction of air flow.

Air conditioner from a plastic container and an exhaust fan

From a rather elegant design solution, the result is a compact device. It is easy to repeat it with your own hands.

What do you need to work

Take a plastic container with a tight-fitting lid. Of the tools, it is enough to get a sharp knife with a sharp end. The lid has two holes. A fan is built into one of them, which takes air from the outside and drives it inside the container. A corner with a diameter of not more than two inches is built into the other hole.

To build a compact, mobile and convenient air conditioner, you will need a small plastic container and a plumbing corner with a diameter of no more than two inches. You can't do without a fan.

Manufacturing guide

The lid has two holes. One is round, its diameter should be equal to the diameter of the fan. The fan is attached from above. It must suck in outside air and drive it inside the container. The container holds two bottles of ice. In another, smaller hole, a sanitary corner is built in. It is a guide for the flow of cooled air.

How to assemble a water cooling plant yourself

Craftsmen design and manufacture cooling systems for a variety of reasons. Firstly, in the July heat, you want to sit in a cool room, and not in a gas chamber. Secondly, not everyone can afford to buy a branded split system. Together with installation, this is a very expensive pleasure. Thirdly, there are still people in the world who love and know how to do useful things with their own hands. And, most importantly, they make them from everything that comes to hand.

Tools and elements for creating a flow-through cooling system

Tools, as a rule, are needed those that are available in every home. Especially where the craftsman lives. The tools are common, since you have to work with plastic, cardboard, thin sheet metal. It is enough to own a sharp knife, metal shears, a hammer and pliers. Not prevent electric drill and soldering iron. Of course, it is good to have a personal workbench with a vise. Still need glue and sealant. The starting material will be plastic bottles, a fan, a plywood shield.

Cooler Assembly Order

From plastic bottles, or rather, from their upper parts, where the neck is located, you can make an air conditioner that does not need a fan and electricity in general. It is necessary to collect 20–30 pieces of plastic bottles, cut off 10–12 cm from them from above and mount them on a plywood board.

Plastic bottle caps also come in handy. A flat part is cut off from the corks, and the cork is used as a nut. It is screwed onto the neck of the bottle from the back of the plywood sheet. The shield must be the size of the window into which this miracle device will be embedded.

Such a block is installed in the window of the room with its necks facing the street. The air entering the narrow neck, when leaving the funnel, expands in volume and has a lower temperature. Not much, but still. Such coolers are widely used in the countries of Southeast Asia.

A good air cooler is obtained from an 8-liter bucket. The order of work is similar to building an air conditioner in a container, only this one will be larger and more powerful. So that the ice in the bucket does not melt longer, inside it you need to make thermal insulation from foam at the bottom and along the body. The bucket can be plastic, which is easier to work with. You can install not one, but 3-4 outlet pipes - and fresh air will immediately go in different directions.

A good fan is built into the lid of the bucket and fixed. A large amount of ice is placed inside, the lid closes and the fan turns on. Everything, the air conditioner worked.
