How to make a home air conditioner with your own hands: popular schemes and instructions

How to clean your air conditioner at home

Knowing how often you need to clean, you need to figure out how to properly clean the device at home. The question of how to wash the air conditioner yourself can be confusing, but in reality there is nothing complicated about it.

To begin with, something should be placed on the floor under the indoor unit, on which dirt will fall in order to wash the split system without soiling the apartment. Then the front cover and protective mesh are removed. Removing the cover of the air conditioner yourself is not difficult. In the case of a bk 1500 air conditioner, you will have filters, a drainage system, a radiator with an evaporator and, of course, a fan in front of you.

How to clean the air conditioner filter

If you want to clean the split system yourself, cleaning the filters is a mandatory step. Filters are the first thing that catches your eye when you remove the cover of the bk 1500 air conditioner. It looks like a fine mesh, dotted with plastic partitions.

Depending on the company, their number varies from one to three. These items require frequent washing. You can even understand how to clean the air conditioner filter intuitively. Washing with cold water, vacuuming or a regular brush is suitable.

The filters must be dried before they are returned to their place.

How to clean the drainage system of the air conditioner

The key to how to clean the drain is in its device. The system consists of a tube and a tray that collects liquid. To remove the latter, it is disconnected from the board, then detached from the drain tube. It is enough to rinse the bath with water.

Now about how to clean the drain pipe of the air conditioner. Usually, a compressor or a vacuum cleaner switched on for blowing is attached to it, and it is simply blown through with a powerful air stream. After the channel is treated with chlorhexidine. It is pumped in and left for 15 minutes. Then the blowing procedure is repeated. These actions will ensure proper cleanliness of the air conditioner drain.

To check the system at home and make sure everything is done correctly, one and a half liters of water is poured into the drainage. The absence of leaks is a sign of high-quality cleaning.

How to clean an air conditioner fan

After removing the filters, the dust is blown out with a vacuum cleaner with a blowing function or with a can of compressed air. Then the drum blades are covered with soapy water. It is better to do this with a suitable brush.

The detergent can be both laundry soap and dishwashing liquid. The fan will get rid of dirt itself when you turn it on. Beforehand, you should put some kind of film under the diffuser grille.

How to clean an air conditioner radiator

Unfortunately, there is no way to clean the radiator thoroughly at home. You will have to limit yourself to surface cleaning.

The radiator of the bk 1500 air conditioner is located under the front panel, which will have to be unscrewed. It is cleaned with an ordinary brush, preferably with a long pile. Then, by switching the system to recirculation mode at a minimum temperature, it is required to spray about half a liter of antiseptic in the air intake area.

How to clean an air conditioner evaporator

The evaporator is cleaned in the same way as the radiator of the bk 1500 air conditioner, but the brush must be driven exclusively from top to bottom, in order to avoid damage to thin plates. The dirt film from the heat exchanger is perfectly removed by a steam cleaner. Then proceed to the treatment with an antiseptic.

You have received enough information on how to clean the air conditioner yourself, but still this does not exhaust the maintenance of climate technology.One way or another, the split system, as it is used, will lose refrigerant, approximately 5% per year, if there was no depressurization.

Therefore, even knowing how to clean the split system yourself, you won’t be able to do without the services of specialists. From time to time, you will have to send the air conditioner to a service center for verification, and then it will delight you with a long and flawless service.

We create a device using copper wire

You can make a homemade duct air conditioner using the following tools and components:

1. any container (for example, plastic, tin, etc.)
2. fasteners - self-tapping screws
3. simple computer disk
4. USB connection cable
5. cpu fan
6. ice

The bottom of the selected vessel is equipped with appropriate holes so that with their help the heat flux penetrates into the system. Screwed self-tapping screws securely fix the disk with ice. It is worth organizing special recesses on it so that the melted liquid drains, and, among other things, in order to optimize ventilation processes.

The cooler should be mounted in such a way that the air mass has an outlet from the outside. Using a cord, the cable is attached to the cooler, and now the entire system as a whole is attached to the system unit.

You see, there are a lot of options for how you can build a ducted air conditioner yourself. The main thing is to have the strength, resources, desire, theoretical base and a number of practical engineering and technical skills.

Air conditioner for car

To build an air conditioner for a car, you can use an old portable refrigerator, which can no longer be repaired.

Attributes for a homemade air conditioner

Operating procedure:

1. First, cut a circle on the refrigerator door with a diameter of about 10 cm.
2. Next, get rid of the rubber seal at the bottom, thereby ensuring air accessibility.
3. Insert a drainage tube there, which must be sealed with a sealant, you can use construction foam.
4. The next step is the installation of fans. The first will blow the compressor, the second will blow out the coolness.
5. Drill holes on the sides for the flow of hot air.

You can install a homemade device in any part of the machine. As you can see, designing a cooler for a car is a doable task.

For more details on the process of turning an old refrigerator into a full-fledged air conditioner for a home or car, you can find it on forums dedicated to this topic, or watch a video.

Making an air conditioner with your own hands is a solution to three problems:

• cooling in the summer heat;
• savings on the purchase of expensive equipment;
• practical disposal of old technology.

If you have a few free hours in reserve and there is no desire to hand over boring equipment for repair, then with a little ingenuity you can get an excellent result. With such work, you can safely brag to your friends and be proud of your ingenuity.

Where to locate the outdoor unit

In fact, this is not the easiest task - to choose a place for the outdoor unit. Not all buildings allow them to be placed on the walls. In this case, there are only two ways out: install the outdoor unit of the split system in a specially designated place - air conditioning. If there is no such room, only a balcony or loggia remains. In such buildings, they are usually glazed, so the placement of the block does not affect the appearance.

But in this case, it is necessary to provide a system for cooling the equipment and removing exhaust air. If the balcony is spacious enough, for the duration of its operation, open windows for ventilation or providing fresh air in some other way. The way out is simple and clear, but it leads to overheating of the equipment, and this is fraught with breakdowns and frequent replacement of the damaged outdoor unit.

Mounting on a balcony is sometimes the only way out

Installing fans for a more active air exchange can slightly improve the situation. It is right to fence off a small room, to make effective ventilation in it, separate ventilation ducts for the removal and supply of air. And they must be separate. This is done with the help of air ducts that lead out instead of part of the glazing. In general, in this case, installing an air conditioner with your own hands is a problematic task precisely in terms of ensuring normal operating conditions for the equipment.

On the balcony or loggia

If there are no prohibitions on placing foreign devices on the walls of the building, usually the outdoor unit of the air conditioner is hung on the balcony railing (side or front) or on the wall, but so that it can be reached for maintenance - wash, clean, check, repair.

If the balcony is glazed, there should be an opening window sash above it. Otherwise, it will be very difficult to serve it. For protection from rain and objects, which can fall from the window, a visor is placed above the block. The choice of materials is something similar to finishing a balcony or a white plastic visor, but only full-bodied.It is better not to use hollow and metal ones (including corrugated board and metal tiles), because during rain they turn into a drum, and during hail they can generally stun.

Standard ways to install the outdoor unit of the split system on the balcony

If the block is placed on the loggia, of all the above options, only the one in the picture on the right remains. it is inconvenient to place it next to the wall, perhaps under the window, but this already belongs to another section.

One more thing: how to run the track - on the ceiling or on the floor? You will have to ditch in both cases, but in the case of the floor, it is possible that you will make it from boards, then the pipes and cables connecting the outdoor and indoor units can be laid on the surface, but better in a box.

Under or next to a window

In those rooms where there is no balcony or loggia, the outer part of the split system is hung on the wall from the outside. It is more convenient if it is located under the window or to the side of it. Moreover, under or next to the opening part. In this case, service is possible without calling a climber.

The outdoor unit of the air conditioner can be installed under or next to the window

When installing the outdoor unit of the air conditioner with your own hands on the wall next to the window, consider the height of its installation. You can position the top surface of the block flush with the top edge of the window. In this case, leaning out of the window and insured, it will be possible to carry out work standing on the windowsill. The second option is to align the lower edge flush with the lower border of the window opening. Here you can lie on your stomach on the windowsill, but you won’t be able to get to the outlet of the pipes. That is, you still have to call industrial climbers.

plastic container air conditioner

For the manufacture of the third option, you will have to tinker a little with its manufacture. For assembly you will need:

plastic container or carton

plastic pipe corner

These usually go to water supply or sewerage.

food foil

scotch

exhaust fan

First of all, glue all the inner walls and bottom of the box with foil.

Install a fan and a plastic pipe neck on top of the lid. Draw around the outline with a marker and cut out the corresponding holes.

The principle of operation is simple. The fan will suck in hot room air, and cold air should already come out through the pipe.

To do this, put ice bottles inside again. Without them, nowhere.

In order to avoid extraneous air leaks, it is advisable to close up the gaps from the holes after installing the tube and the fan with adhesive tape.

Plug in the plug from the hood into the outlet and enjoy the coolness. Such a home-made air conditioner can cool the room by almost 7-8 degrees in half an hour.

Which is a more than acceptable result for such a cheap DIY model. Not all outdoor mobile air conditioners are able to cope with this task.

At the same time, there will be no puddles, basins and security problems around. Bottled ice will, of course, melt, so it's best to use plastic containers rather than cardboard boxes.

Someone on the Internet advises replacing regular bottled ice with dry ice. This is supposed to keep the moisture out. Do not listen to such advisers.

Dry ice, when evaporated in confined spaces, releases dangerous levels of carbon dioxide. Therefore, it is even recommended to transport it only in the trunk.

Vacuum for what and how to do

Vacuuming is necessary in order to clean the copper pipes from air and moisture that gets inside during installation. If it is not removed, a large load will be created, and the compressor, accordingly, will overheat.

There are two ways to pump out a split system.

Puff method

If you look at the port into which the copper pipes are connected, you can see two plugs, in addition to the nut with the fitting. Both plugs are unscrewed.

Work is done with a port of larger diameter. Inside there is a special slot for a hex key. The size is selected according to the place, and it can also be found in the instructions.

Turn the valve 90 degrees for 1 second with the key, then release it. This means that a little freon was released into the system, which led to excessive pressure. On the same port there is a spool, which must be pressed with a finger to start the release of a mixture of freon and residual gases.The operation is carried out 1-2 seconds 2-3 times.

After all, a plug is put on the spool, and the port with a hexagon is unscrewed completely to let the freon into the system

It is important to make sure that all plugs are tightly screwed in, you can lubricate the threads with soap for greater sealing.

Vacuum pump

The vacuum pump is connected to the spool for 20-30 minutes. During this time, he must completely evacuate the system. Then the pump is turned off, but the tube remains in the spool for 15 minutes. This is necessary in order to observe the pressure with a pressure gauge. If the arrow freezes and stays in place, then everything is fine. The chaotic movement of the arrow indicates an air or moisture leak, so you should turn on the pump again.

Before disconnecting the pump, it is necessary to let freon into the system using a hex key. A characteristic sound in the system indicates a successful launch. After that, you must quickly disconnect the pump.

Do-it-yourself installation of a split system consists of installing blocks and laying all necessary communications

It is important to follow the instructions from the equipment manufacturer, because each model has its own characteristics that affect the installation method and location.

3 id="installation-vnutrennego-i-naruzhnogo-bloka">Installation of indoor and outdoor unit

The installation of the indoor unit begins with the selection of a location. Make sure that there are no electrical communications and water pipes in the attachment points.

First of all, a plate is attached, on which the block itself is then put on.It is necessary to fulfill a prerequisite, the horizontal level of the split system plate must be ideal.

After working with the level, you should put marks for the holes

It is important to fix the bottom of the plate well, where the latches for the body of the indoor unit of the split system are located.

After successful installation of the plate, the indoor unit is put on from above and goes into the grooves, which allows it to be firmly held on the wall.

The opening for communications should be at such a height that the drain pipe slopes towards the outdoor unit (slope - 1 cm per 1 m). The diameter of the hole must be at least 5 cm. It is better to make two holes - for wires with copper pipes and separately for a drainage tube.

To mark the mounting of the outdoor unit, remember that again you need to observe the level and the fact that the drain pipe must go along the slope. Accordingly, the level of the outdoor unit is lower than the level of the indoor unit of the split system.

Brackets are installed first. Each hole in them must be used for its intended purpose. The more anchors will hold the base, the greater the chance that the block will not fall. Installation of the block itself on the brackets is carried out using bolts.

Laying communications

The first step is to lay copper pipes. Having decided on the length, they are cut with a special tool, which was indicated above. The edges must be carefully filed.

Insulating pipes are put on top of the pipes, which serve to maintain the temperature. There should be no insulation joints. From above, everything is tightly glued with reinforced tape

Important! When pulling pipes through the hole, it is necessary to block access to the inside to avoid dirt and construction debris

The cable is easy enough to run. Stripped wires of the required size are pulled through the hole and connect the split system blocks.

To find where to connect the wires, you need to open the cap, which is located above the copper pipe mounts on the blocks. It is recommended to study the wire fasteners before installing the system so that there are no problems during the process.

How to properly remove the air conditioner

There are three prerequisites to remove the air conditioner yourself:

• The outdoor unit must be within reach. If it stands on the facade of an apartment building above the level of the second floor, then it can only be dismantled from a window or balcony. Otherwise, you need to involve industrial mountaineering specialists.
• To remove heavy blocks from the wall and properly turn off the compressor, at least one assistant is needed.
• It is necessary to rent a manometric station specifically for the type of freon that is pumped into this model of air conditioner.

Note. The last point concerns stations with conventional (pointer) pressure gauges. Digital manifolds are configured for the brand of refrigerant.

Overview of the design of the outdoor unit before connecting the air conditioner: diagram and structure

When installing an air conditioner with your own hands, it will be useful to familiarize yourself with its structure. This will avoid mistakes in the process of work and better master the technology.

The design of the outdoor unit consists of the following components:

• fan
• compressor;
• condenser;
• four-way valve;
• filter;
• control boards;

To install the air conditioner with your own hands, you need to familiarize yourself with its structure.

• union type connections;
• protective cover with quick release design.

The fan generates air currents that blow around the condenser. In it, freon is subjected to cooling, and its condensation occurs. The air that is blown through this radiator, on the contrary, heats up. The main function of the compressor is to compress freon and keep it moving inside the refrigeration circuit.

There are two types of compressors:

• spiral;
• piston.

Piston compressors are cheaper, but less reliable. Unlike spiral ones, they react worse to the effects of low temperatures in the cold season. When connecting an inverter air conditioner, the control board is usually located in the outdoor unit. If the model is not inverter, all electronic components are placed in that part of the split system that is installed indoors. This is done in order to protect the control board from humidity and temperature extremes.

The design of the external block includes the following units: compressor, valve, fan.

Four-way valves are commonly found in reversible types of air conditioners. Such split systems operate in two modes: "heat" and "cold". When the air conditioner is set to heat, this valve changes the direction of the refrigerant flow. As a result of this, the functionality of the blocks changes: the internal one starts to heat the room, and the external one works for cooling. Union fittings are used to connect copper pipes that connect the indoor and outdoor units.

The freon system filter prevents copper chips and other particles from entering the compressor.In the process of installing the air conditioner with your own hands, small debris is formed. The filter traps particles before entering the compressor.

On a note! If the installation of climate equipment is performed in violation of technology, a large amount of debris can enter the system. In this case, the filter will not cope with pollution.

The quick-release cover is designed to protect the terminal block intended for connecting wires and fitting connections. In some models, it provides partial protection by covering only the terminal block.

 
Regardless of which structural type the split system belongs to, its outdoor module always has the same working units.

Dismantling in winter

Air conditioning can work in winter. And not only as a heater, but also in cooling mode (for example, in rooms where servers are located).

Note. It is possible to collect freon in the condenser of the outdoor unit only when operating in cooling mode - in heating mode it already works as an evaporator.

The peculiarity of working in winter in this mode is that there is a lower temperature limit, which is affected by the type of refrigerant, the type of air conditioner and additional equipment. This dependence is also associated with the characteristics of the compressor device - it is oil-based, and the oil thickens at low temperatures. For conventional air conditioners, the lower operating temperature ranges from + 5 ° C to -5 ° C, for inverter - up to "minus" 15-25 ° C.

Before dismantling the split system, these nuances must be taken into account. And if the temperature is below the specified limit, and the air conditioner is not equipped with a “winter kit” with compressor crankcase heating, then to remove the outdoor unit, you must use a freon pumping and collection station (it has an oil-free compressor).
