Abstract: A vertical discharge condenser includes a generally cylindrical heat exchanger having a vertical interruption between a first and a second end of the heat exchanger, a panel enclosing the vertical interruption in the heat exchanger to form an uninterrupted generally cylindrical enclosure, a generally circular fan grille enclosing a top of the cylindrical enclosure, and a generally circular base pan enclosing a bottom of the cylindrical enclosure.

Abstract: A heat pump system includes a compressor, a reversing valve, an outdoor heat exchanger and an indoor heat exchanger in a circuit, and a refrigerant-to-water heat exchanger. 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 is passed through refrigerant-to-water heat exchanger. A refrigerant reservoir may be provided for use in refrigerant charge control. A refrigerant line (71) couples reservoir to the refrigerant circuit intermediate the outdoor and indoor heat exchangers for directing liquid refrigerant into the reservoir and a refrigerant line (73) couples the refrigerant circuit upstream of the suction inlet to the compressor for returning refrigerant to the refrigerant circuit. A controller controls flow into and from the refrigerant reservoir through selective opening and closing of control valve (72) in line (71) and control valve (74) in line (73).

Abstract: 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, 55) 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 line (35). A refrigerant reservoir (70) may be provided for use in refrigerant charge control. A refrigerant line (71) couples reservoir (70) to the refrigerant circuit intermediate the outdoor and indoor heat exchangers for directing liquid refrigerant into the reservoir (70) and a refrigerant line (73) couples the refrigerant circuit upstream of the suction inlet to the compressor (20) for returning refrigerant to the refrigerant circuit.
