In this article we are going to discuss the detailed dismantling procedure, inspection, and assembling procedure of a refrigeration compressor as used on-board ships.

It basically does the following: takes suction from the evaporator and compresses it to increase its temperature and pressure so that the refrigerant will be able to circulate throughout the system. The basic function of using a refrigeration compressor is to provide the force required for the refrigerant to circulate.
