Abstract

Heat pump apparatus (10) is provided that includes a compressor (26) a first heat exchanger (18) connected to the compressor's discharge and configured to transfer heat to the water, a second heat exchanger (20) and a third heat exchanger (36), with a fan (22) configured to force air to flow over the second heat exchanger (20), an expansion valve (24) between the second and third heat exchangers, a valve (28) connected to the three heat exchangers (18,20,36) and to the compressor (26), and a switch (30) that is configured to control operation of the fan (22). Water is heated in the apparatus (10) by compressing a fluid in the compressor (26) and passing it to the first heat exchanger (18) to transfer heat to the water in the heat exchanger, passing the fluid to the second and third heat exchangers (20,38), reducing fluid pressure in the expansion valve (24), absorbing heat in the first and/or second heat exchanger (20,36), returning the fluid to the compressor (26) and controlling the fan (20) to maintain fluid pressure between the compressor (26) and the first heat exchanger (18).
