Embodiment Construction

[0029] As shown in the first embodiment of Figures 1-5 and the second embodiment of Figures 6-8, the coolant heat pump system not only provides heated or cooled air to suitable areas such as indoor areas located within a building (not shown) , and provide auxiliary water heating. The system includes a compressor 20, a suction accumulator 22, a reversing valve 30, an outdoor heat exchanger 40 and associated fans located on the outside of the An associated fan, a first expansion valve 44 operatively associated with the outdoor heat exchanger 40 and a second expansion valve 54 operatively associated with the indoor heat exchanger 50 . The coolant circuit comprising coolant lines 35, 45 and 55 provides a closed loop coolant flow path connecting these components in a conventional manner for heat pump systems employing the known Carnot vapor compression cycle. Additionally, the system 10 includes a coolant-to-water heat exchanger 60 through which coolant passes in heat exchange rel...

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. A controller (100) controls flow into and from the refrigerant reservoir (70) through selective opening and closing of control valve (72) in line (71) and control valve (74) in line (73).

Description

technical field [0001] The present invention relates generally to a heat pump system, and in particular to a heat pump system including auxiliary liquid heating, including for example heating water for swimming pools, domestic water systems and the like. Background technique [0002] Reversible heat pumps are well known in the art and are commonly used to cool and heat climate-controlled suitable areas of a residence or building. A conventional heat pump consists of a compressor, suction accumulator, reversing valve, outdoor heat exchanger with associated fan, indoor heat exchanger with associated fan, expansion valve associated with outdoor heat Operate the associated second expansion valve. The described components are usually arranged in a closed coolant loop pumping system employing the well known Carnot vapor compression cycle. When operating in the cooling mode, excess heat absorbed by the coolant passing through the indoor heat exchanger as it passes through the out...
