Since only refrigerant will condense on the strain designed with the purge unit, the air together with other non-condensable that collects on major may be purged manually or instantly by way of valve on the environment.

Reciprocating compressor utilize a piston sliding within a cylinder to compress refrigerant vapor. Determine four-29 shows the theory of Procedure of the reciprocating compressor. In determine 4-29A,the piston has moved downward from the cylinder, A. It's moved refrigerant vapor from the suction line by means of consumption valve.
