Heat exchange system with heat pump - has counterflow heat exchange contact to transmit heat or refrigerating effect

摘要

The heating or cooling effects are transmitted between two separated fluid streams by means of a heat pump. The latter has a circuit with an evaporator, compressor, condenser and a throttle valve. The evaporator and condenser are brought into heat exchange contact with the separate fluid stream. The heat pump has high efficiency. The fluid stream is brought into counterflow heat exchange contact upstream of the evaporator with the refrigeration circuit between the condenser and the throttle valve. The fluid stream leaving the condenser is brought into heat exchange contact with the fluid stream entering the condenser. The fluid stream (76) leaving the evaporator (41) flows through counterflow refrigerator.
