Refrigerating heat pump circuit - uses compressors for skating rink formation and hot water prodn.

摘要

The circuit is laid out to make it possible to use the output of refrigerating compressors for the simultaneous operation of a skating rink and reject heat from a heat pump hook-up for producing heat for heating and hot water preparation. The refrigerating compressors (3) and (4) suck refrigerant vapor either from receiver (1) or from heat exchanger (2) designed as evaporator. The compressor discharge the hot gas via heat exchanger (5) into heat exchanger (6) from which heat for the warm water circuits (7) is taken. The exchanger (5) is fitted with another water coil which takes off heat for production of hot water of higher temperature in circuits (7). The valve set (11) to (15) can be manipulated in such a manner, that part of the refrigerant vapors is taken from receiver (1) and part from heat exchanger (2).
