The invention provides a heat pump heating system which comprises a compressor, a heat exchanger one, a throttling device, a heat exchanger two and a water tank. A cold medium outlet of the compressor is connected with one end port of a cold medium pipe of the heat exchanger one, a cold medium inlet of the compressor is connected with one end port of a cold medium pipe of the exchanger two, and the other end port of the medium pipe of the heat exchanger one is connected with the other end port of the cold medium pipe of the heat exchanger two. A water outlet of the heat exchanger one is connected with a water inlet of the water tank, a water inlet of the heat exchanger two is connected with a tee fitting one, and a water output of the heat exchanger two is sequentially connected with a check valve, an electric control valve and a tee fitting two, the tee fitting one is connected with the tee fitting two, and the tee fitting two is connected with the water inlet of the heat exchanger one. Due to the tee fittings and the electric control valve, control of returning water transported to the heat exchanger two and providing evaporation heat resource for the heat exchanger two is achieved, and heat-collecting and running of the heat pump heating system without interference from outside ambient temperature is achieved, and heating efficiency of the heat pump in a low temperature environment is improved.
Description
technical field [0001] The invention relates to a heat pump, in particular to a heat pump heating system. Background technique [0002] At present, the air source heat pump system usually includes a compressor, a condenser, a throttling device, an evaporator, and a water tank, and the compressor, condenser, throttling device, and evaporator are connected together. During the heating process, the refrigerant in the evaporator absorbs the low-temperature heat in the air and vaporizes, and then becomes a high-temperature refrigerant after being processed by the compressor. Brine (such as: water) for heating. It can be seen from the above that if the heat pump heating system in the prior art operates in a low temperature environment (below -15 degrees Celsius), the heat exchanged between the evaporator and the outside air will obtain less heat, and there will be serious frosting, which will cause the existing The air source heat pump system in the technology has very low heati...
