The function of the AC compressor

What do you know about the air conditioning compressor (Air Conditioner)?

The compressor is a mechanical device that served to suck the refrigerant vapor from the evaporator. Then pressed compress) and thus the temperature and vapor pressure becomes higher. Compressor task is to maintain the pressure difference in the system. Compressor or pump suction refrigerant to the press serves the entire cooling system. The system works by changing the pressure to move from high pressure side to the lower side of our humble. The higher the temperature the greater the pumped energy released by the compressor.

Suction valve

These valves incorporate a refrigerant gas into the cylinder or piston chamber. Compressor suction power and the ability depends on the speed of movement and kecapatan air from all parts associated with this valve. These valves are usually made of special steel (stainless valve compressor).

Remove the valve

Exhaust valve duty to dispose of the gases out of the cylinder or piston chambers. The exhaust valves are usually made from the same material with suction valves

valve service

This valve berguan to test the compressor and cooling system repair

Bak Shelter (Reservoir)

Lubrication oil reservoir is required for all bagina-section. Usually like crank (crank case) is used as a bath oil pemapung, except on large compressors that have a special lubrication system.


The following types of compressors and a description of explanation:

1. Compressor commute

Alternating compressor is a type that is widely used. This compressor can be single or double cylinder. Named compressor back and forth, because the motion toraknya forth in the cylinder. The length of the piston movement is called step (stoke) or stride length. The length of this step is usually the same as the diameter of the cylinder.

Compressor capacity depends on factors: the number of cylinders, stride length, the number of revolutions per minute and others. The motion of the piston back and forth is obtained from the crankshaft which receives motion from the electric motor.

For how it works, journey into the refrigerant from the compressor and regulated by the exhaust valve (discharge) and the suction valve (suction). Pebuang refrigerant out through the valve and enter through the suction valve. When the piston moves away from the valve, then this step is called suction-stroke and the pressure will be reduced. Therefore, the pressure in the compressor is lower than the pressure of the suction line, the refrigerant vapor into the compressor.

If the piston moves closer to the valve, the pressure in the compressor suction valve closed rose so. While the exhaust valves open causing the refrigerant vapor flow kesaluran press (discharge line) outside. And so on.

2. Rotary Compressor

These compressors have the same task with bolakbalik compressor, which compress the gas in order to make a difference in pressure on the system and menabah refrigerant flow from one section to another. Compaction process gas or vapor refrigerant performed by bullets (roller). See figure 5. In this figure swivel ball rotates on an axis eccentric in a space that is parallel to the axis. This space is called the pump.
