Construction and principle of of the air conditioner

To describe the design and function of the air conditioner, answer the following question.
How to get a cold?

It is well known property of a liquid to absorb heat during evaporation. To see this, it is possible to carry out experiments. Take the gas cartridge and try to fill the lighter. Liquefied natural gas that does not fall into the cigarette lighter, and you will get on your hands, will evaporate, and you will feel very cold, down to frostbite. If there is no gas cartridge, use alcohol or cologne. Pour it on his hand, lightly to blow and feel a chill. Thus, the theory that liquid evaporation absorbs heat proved.

How does this apply in practice? Send to a tube (radiator) liquefied gas, use a fan to cool the radiator, gas will evaporate, absorbing heat and at the output we get a cold air stream. However, gas will come out the other side of the radiator, and to the input of need to constantly apply new portions of the liquefied gas. Therefore, the system must be of a closed, that would be one and the same gas (refrigerant) used repeatedly. Moreover, the vaporized gas to condense again, lead to a liquid state, for the subsequent evaporation, during which will be the absorption of heat.

So, proceed to the creation of the air conditioner. We already have one part of it, this is the evaporator, from which issues gas. This gas must be brought to a liquid state, for later use. Have to file this gas to the compressor intake , the output of which we get compressed gas, due to compression of the gas temperature will rise. Apply compressed, hot gas in the next radiator, which will blow the air, whose temperature is lower than the gas temperature. In consequence of that, there will be condensation of gas and turn it into a liquid. We call this radiator condenser, since it condenses the refrigerant (gas). Next, you need to lower the pressure and from liquid to gas the gas-liquid mixture, for what would be the mixture is completely evaporated in the evaporator (for refrigeration), prior to entering the compressor for recycle. This is done by means of thermostatic expansion valve (TEV). Thermostatic expansion valve adjusts the amount of refrigerant flow to the evaporator.

Below is a practical scheme conditioner (split system).

The cost of repairing the air conditioner

To determine the cost of repairing the air conditioner is necessary diagnosis. The approximate cost of repairing air conditioners, can be determined if the external manifestations of the problem.
