DUAL CENTRIFUGAL CHILLER

摘要

PURPOSE: A dual refrigerator is provided to secure the optimum performance of compressors by lowering the pumping head of two compressors and keeping them equal. CONSTITUTION: A dual refrigerator comprises first and second evaporators, first and second condensers, and first and second compressors. Cold water passes through the first evaporator(111) and the second evaporator(112) in order. Cooling water passes through the first condenser(121) and the second condenser(122) in order. The first compressor(131) containing coolant connects the first evaporator and the second condenser. The second compressor(132) containing coolant connects the second evaporator and the first condenser.
