Abstract (en)
A heat pump has a compressor 1, a first heat exchanger 3 (evaporator), an expansion valve 2 and a second heat exchanger 5 (condenser). The first heat exchanger 3 exchanges energy with the air to be cooled and is provided with a fan 6. The second heat exchanger 5 exchanges energy with tap water and for this purpose is connected to a water pipe 15, 16. The heat pump also has a third heat exchanger 4 for preheating or pre-cooling the tap water through the heat transfer medium to save tap water if it is hot in the summer or cold in the winter. The flow of the heat transfer medium through the third heat exchanger 4 can be controlled by a control valve 7 and the supply line 15 of the tap water can first be led through the third heat exchanger 4 by means of shut-off valves 9 and 12 before being sent to the second heat exchanger 5.
