Abstract (en)

[origin: WO2006128264A1] A heat pump system (10) includes a compressor (20), a reversing valve (30), an outdoor heat exchanger (40) and an indoor heat exchanger (50) coupled via refrigerant lines (35, 45) in a conventional refrigeration circuit, and a refrigerant-to-water heat exchanger (60). In the air cooling with water heating mode, the air heating with water heating mode and the water heating only mode, water from a water reservoir (64), such as a storage tank or swimming pool, is passed through heat exchanger (60) in heat exchange relationship with refrigerant passing through an additional refrigerant line (27) that establishes a fluid flow path through the heat exchanger (60) into the refrigerant circuit intermediate the outdoor heat exchanger (40) and indoor heat exchanger (50). A refrigerant reservoir (70) may be provided for use in refrigerant charge control.
