Mechanical energy in the motor is converted to energy by the compressor so pneumatis coolant circulates in the air conditioning system installations.

Generally consists of two types of compressors is as follows:
1. Piston type compressor
To inhale and coolant pressure by movement in the cylinder piston compressor.
2. Rotary type compressor
The rotor is the part that rotates in the stator. The rotor consists of two propellers. Suction step occurs when the entrance began to open and ends after a closed door. At the time the entrance was closed beginning tap steps, until the vent valves open, while at the same time the entrance was happening suction step, demikan so on.
Advantages:
a. Since each round produces suction steps and press at the same time, the moment the play is more equitable as a result of vibration / shock is smaller.
b. Size dimensions can be made smaller and save space.
Disadvantages:
Until now only used for air-conditioning systems for small to large volume, the house and have greater rotornya and fans on the rotor is not strong enough to keep hold of friction.
Rotor movement inside the stator and the compressor will suck coolant pressure. Compressor works to raise the pressure refrigerant, the compressor sucks low pressure refrigerant from the evaporator and compress up to 100-250psi. With increasing the temperature of the refrigerant refrigerant will increase, refrigrant pressurized steam in the compressor tingggi will condense more quickly by releasing heat to the surroundings.
AC Compressor lubricant should be given. The primary function of lubricating the compressor is to cushion the komppresor and as a lubricant on the rubbing parts. Oil used in the compressor oil is not just any special olitetapi because oil will be circulated in the cooler.
If one component damage during cooling to work, then some oil in the compressor will be left in the refrigerant cycle. If the component is replaced by the oil needs to be supplemented to replace the remaining oil in the damaged components. Depending on the number of oil from the replaced components.
Lubricating oil in some of the air conditioning system went out together and circulate refrigerant in the cooling cycle. If the oil circulating with refrigerant enough, lubrication oil in the bathtub crank that can occur less overheating (overheating). Meanwhile, if oil bersma circulating refrigerant is not fixed, then it collects in the oil evaporator. This will interfere with heat transfer in the evaporator.
