In order to choose any technique you should be familiar with the way it works. That is why I will try to give you guidance in the basic elements of the air-conditioning equipment, which determines its good work. One of the most important units in the air-conditioning is the compressor. Its function is to increase the pressure of working gas (freon) and to move it throughout the system. When going around the shops and exploring different models you will be offered to choose between: conventional, inverters and DC inverters air conditioner. All these names come from

the type of compressor

which is in the air-conditioning or rather from the mode of operation of the electric motor that drives the plunger or the screws of the compressor. Electric motor, turns electricity in the working gas pressure. What you need to know here is that the electric motor can be a constant power or its power to change depending on conditions. In all cases

manageable power

is preferable than the constant and that is why the compressors, which have this opportunity are more sought. These include inverters air. On the other hand, the management of electric motor power is not the only important parameter. More important is the performance of this motor (CPA). This is about how much energy consumed by the electric grid is transformed into the wanted. (hot or cold air). In the case of air conditioner,the energy is used to increase the pressure of the working gas. The purpose of the electric motor is not to convert electrical energy into heat, but to transform it into an increasing domestic energy state of gas, which is expressed in pressure. That is the reason the compressor,which is a set of electrical and mechanical elements that affect the working gas to be the most important part of the design of air conditioning.
