FREEZING APPARATUS HAVING RECIPROCATING COMPRESSOR

摘要

PURPOSE: A freezing apparatus having a reciprocating compressor is provided to improve the lubricating performance of a reciprocating compressor and improve the performance of a freezing apparatus by using paraffin base lubricating oil chemically attracted to hydrocarbon. CONSTITUTION: An evaporator(2) executes a cooling action by vaporizing a refrigerant. A reciprocating compressor(4) compresses the refrigerant by reciprocating a mover to compress the refrigerant discharged from the evaporator. A condenser(6) changes the compressed refrigerant into a liquid refrigerant. A capillary tube(8) reduces a pressure of the refrigerant to transmit the refrigerant to the evaporator. The refrigerant is a kind of natural refrigerants, hydrocarbon and the lubricating oil is paraffin base lubricating oil.
