Heating pump for hot water has a heat exchanger connected to a compressor on the same circuit and equipped with a second heat exchanger so that both exchangers can be switched into the circuit and used to heat various objects

摘要

The heating pump is used to heat water for swimming pool, domestic or office use. It has a compressor(1) connected to the same circuit which using an on-off valve (2) can be switched onto one of two heat exchangers (3) and (4). Both are connected to an accumulator(5) in which the refrigerating agent is led. It is transmitted (5a) through a filter dryer (6) used to clean it and rid it of moisture, after which it is led through an expansion valve (8). The valve is connected to an air cooler (9) which absorbs the remaining heat. The heat taken from the agent is, after compression, conducted to the heat exchanger through use of the on-off valve. In this way the power of the compressor motor can be used for heat.
