Different Types of Air Conditioning Compressors

The Five Main Types of Air Conditioning Compressor

In a previous post, we discussed the various types of refrigeration compressor. Most firms manufacture both refrigeration and air conditioning models. Between the two applications, the types and popularity of different engineering approaches varies, and they are virtually never cross-compatible.

The most common types of air conditioning compressor include:

1. Reciprocating Air Conditioner Compressor, we supply bitzer compressor, carlyle compressor , copeland semi hermetic cmpressors. 

The reciprocating AC compressor has the longest service history and is the most similar to comparable refrigeration compressors. A piston compresses the air by moving up and down inside a cylinder. The vacuum effect created by this motion sucks in the refrigerant gas. A reciprocating AC can suffer failures related to piston wear-out, but the potential to use up to eight cylinders makes it highly efficient.

2. Scroll Air Conditioning Compressor, we have copeland scroll compressor, hitachi scroll compressor, daikin scroll compressor and mitsubishi scroll compressor .

The scroll compressor is a newer innovation and consists of a fixed coil, the scroll, that makes up the unit’s center. A second coil rotates around the central scroll, compressing the refrigerant and driving it toward the center. With fewer moving parts, the scroll compressor is noticeably more reliable.

3. Screw Air Conditioning Compressor,  include carrier screw compressor, bitzer screw compressor and hitachi screw compressor. 

Screw compressors are typically restricted to large commercial buildings with lots of air to circulate and cool. The unit contains a pair of mated helical rotors that push air from one side to the other. Screw compressors are among the most reliable and efficient around, but not cost-effective for smaller applications.

4. Rotary Air Conditioning Compressor, we have mitsubishi air conditioner compressor, toshiba rotary compressor, LG rotary compressor.

Rotary compressors are the preferred option when operating noise is a factor. They are quiet, have a modest footprint, and do not suffer from vibration as much as other compressors. In the unit, a bladed shaft rotates within a graduated cylinder to push and compress refrigerant at the same time.

5. Centrifugal Air Conditioning Compressor

A centrifugal AC compressor is reserved for the largest HVAC systems. As the name implies, it pulls the refrigerant in using centrifugal force. The gas is then compressed using an impeller. Because of their intended use, centrifugal compressors are among the largest and most expensive.

How Are Air Conditioning Compressors Different from Refrigeration Compressors?

There are key differences that ensure you should never try to replace a compressor rated for AC use with one rated for refrigeration or vice versa. Rarely, it may be possible, but would be extremely inefficient. The compressor can fail without warning, and may damage the entire HVAC or refrigeration system.

Some major points of variation include:

  • Different refrigerant used, which can cause instant system failure
  • Differences in refrigerant pressure throughout the cooling process
  • Configuration of the evaporator and condenser coils
  • Operating temperatures of the condenser coils
