Surprisingly enough, the screw compressor was invented in 1878. However, commercial application developed slowly because of its inability to match tight tolerances with existing manufacturing…

There are two major types of vane compressors, single-vane (rotary) and multivane. A rotary compressor simply consists of a bladed, eccentric rotor in a cavity.…
A great majority of reciprocating compressors which compress the refrigerant gas only on the forward stroke of a piston are built to be single acting…
Open reciprocating compressors with a shaft seal and an external drive motor suitable for a range of prime movers are also available up to about…
In larger sizes, refrigeration compressors are often semihermetic, i.e. although motor and compressor are within one casing, this casing may be unbolted, and the refrigerant…
Compressors are preferable on reliability grounds to units primarily designed for the smaller range of temperatures required in air conditioning or cooling applications. In small…
In a refrigeration cycle, the compressor has two main functions within the refrigeration cycle. One function is to pump the refrigerant vapor from the evaporator…
In reality, rotary compressors are of four general design configurations: (i) rolling piston, (ii) rotating vane, (iii) screw, and (iv) scroll. Therefore, rotary compressors have…
