Multi-stage refrigeration system centrifugal compressor repair instructions After the centrifugal compressor of the cascade refrigeration system is disassembled, the dimensions of each journal (cooperating with the impeller, bearing, coupling, etc.) the evaporator with the first unit cools the condenser of the second unit). Cascade refrigeration system is the combination of two single stage vapour compression system together, condenser of LTC and evaporator of HTC is cascaded and forms the heat exchanger where evaporator cascade absorbs the heat from the condenser cascade which further leads to better refrigeration effect . This allows the unit to operate at a lower temperature and pressure than is possible with the same size single-stage system. Multistage system of cooling is widely used there, where ultra-low temperatures are required, but can not be produced economically through the use of a single-stage system.
