Types Of Compressors

Three categories of compressors is typically used for cooling duties are divided into various types of compressors that share common characteristics. Piston and rotary compressors, piston machines. Volumetric means that these compressors use mechanical means to reduce the amount of vapour refrigerant in the compression process. In a piston compressor piston moving in a cylinder reduces the volume occupied by the refrigerant, causing it to vapor molecules together, as this increases its pressure.

Rotary compressors are roller vane, or share scroll form component that rotates in a special form of a cylinder or scroll to gradually reduce the amount of space occupied pairs, increasing its pressure. Centrifugal compressors are not piston machines, because they do not use the volume reduction strategy of increasing the pressure of the refrigerant. Instead, they use the impeller is rotating fluid at high speed and send it in a special shape of the channel. As a high pair is die channels, most of his speed, pressure is converted to static pressure. This is the same method employed by the fans and pumps. Regardless of the strategy used by a system to squeeze its refrigerant vapor, increasing the pressure produces a corresponding increase in its saturation temperature. This allows an increase of the refrigerant for heat transfer in the environment, thereby changing its state to a liquid so that the refrigerating cycle may continue...
