One key difference is that reciprocating compressors use pistons while rotary compressors do not. In the evaporator, the liquid refrigerant absorbs the heat again and converts itself into a low pressure, high-temperature gas, the cycle then continues like that. After knowing what a compressor is, now it’s time to know some other things. In comparison with the reciprocating compressors, rotary compressors don’t make much noise. Reciprocating piston compressors are most often seen for high-pressure / low flow applications (up to 30 bars), while rotary screw compressors are used for continuous applications (high flow, 7 or 8 bar).. There are two types of compressors used in the air conditioner, Rotary compressor, and reciprocating compressor. Rotary Compressor. In the compressor, the refrigerant gas is pressurized with the help of the compressor motor and thus increases the pressure and temperature of the refrigerant. Another difference is that oil is used to seal the gaps between the rotary’s screws during compression while the reciprocating pumps have piston rings that will eventually wear out. These rotors are mainly designed with very little clearance between them. The movement of the piston creates pressure on the refrigerant and thus the pressure and temperature of the refrigerant get elevated.
