Embodiment Construction
[0052] Such as Figure 1-8 As shown, the present invention provides a heat pump air conditioning system, which includes:
[0053] compressor 1;
[0054] Inner unit heat exchanger 2, outer unit heat exchanger 3 and throttling device 4;
[0055]A refrigerant circulation loop, connecting the compressor 1, the internal heat exchanger 2, the external heat exchanger 3 and the throttling device 4 in series;
[0056] The heat storage module 5 is arranged in the refrigerant circulation circuit to absorb heat from the refrigerant in the refrigerant circulation circuit to store heat when heat storage is required, and to store heat through the heat storage module when it is necessary to defrost the external machine heat exchanger. The refrigerant in the refrigerant circulation circuit is heated.
[0057] By setting up a heat storage module, it is arranged in the refrigerant circulation circuit to absorb heat from the refrigerant in the refrigerant circulation circuit to store heat when...
