Water/air heat pump for refrigerating unit, has hot battery placed in upstream of cold battery with respect to direction of air, where cold battery is heated by thermal conductivity effect due to hot battery

摘要

The pump has a hot battery placed in upstream of a cold battery with respect to the direction of air, where the cold battery is heated by thermal conductivity effect due to the hot battery. A refrigerant exits a compressor (C) via an outlet side (R) at cold gas state and under high pressure, and is condensed in the cold battery after passing via a four way valve (V).
