According to the numerical simulations of the compression process of the reciprocating compressor, it shows that the power consumption is reduced under the approximate isothermal compression process compared with the adiabatic compression. Since the approximate isothermal compression process can be achieved by using oil lubrication system, numerous tests of using the oil lubricants has been done and the optimal intake volume is gained so the COP value of the compressor reaches the highest.
