Embodiment 1
[0045] This embodiment discloses a heat pump air conditioner. The heat pump air conditioner is provided with a refrigeration system 1. The refrigeration system includes an indoor heat exchanger, an outdoor heat exchanger, a throttling device, a compressor, a heat storage device, a first valve assembly, and a second valve assembly. Assemblies, the refrigeration system 1 connects the indoor heat exchanger 15, the outdoor heat exchanger 17, the throttling device 16, the compressor 11, the heat storage device 13, the first valve assembly and the second valve assembly through refrigerant to form a refrigeration circuit. The outdoor heat exchanger 17 in the refrigeration system 1 includes a first outdoor heat exchanger 171 and a second outdoor heat exchanger 172, wherein the first outdoor heat exchanger 171 is arranged on the first heat exchange branch 197, and the second outdoor heat exchanger The heat exchanger 172 is arranged on the second heat exchange branch 198; the first heat ...

The invention provides a heat pump air conditioner. The heat pump air conditioner is provided with a refrigeration system, wherein the refrigeration system comprises an indoor heat exchanger, an outdoor heat exchanger, a throttling device, a compressor, a heat accumulation device, a first valve assembly and a second valve assembly, and connects the indoor heat exchanger, the outdoor heat exchanger, the throttling device, the compressor, the heat accumulation device, the first valve assembly and the second valve assembly through a refrigerant to form a refrigerating circuit. When the heat pumpair conditioner is in a defrosting mode, one of a first outdoor heat exchanger body and a second outdoor heat exchanger body achieves the effect of a condenser to conduct defrosting on itself, and theother outdoor heat exchanger body achieves the effect of an evaporator to maintain operation of indoor heating. The heat pump air conditioner is furthermore internally provided with a heat accumulation branch and the heat accumulation device arranged on the heat accumulation branch, wherein the heat accumulation branch is connected with the outdoor heat exchanger, and the heat accumulation deviceincreases temperature of the refrigerant flowing through the heat accumulation branch, so that the defrosting efficiency of the outdoor heat exchanger in the defrosting process is higher, the effectis more significant, the defrosting time is shortened at the same time, and the influence of heat exchange of the outdoor heat exchanger on indoor heating is reduced.
Description
technical field [0001] The invention relates to an air conditioner, in particular to a heat pump air conditioner, and the invention belongs to the technical field of air conditioners. Background technique [0002] The heat pump air conditioner operates under low temperature conditions, and the outdoor heat exchanger will frost, which will reduce the heating capacity of the air conditioner. Therefore, it is necessary to defrost the outdoor heat exchanger of the air conditioner, and the existing defrosting method includes refrigeration cycle defrosting. There are two kinds of frosting and hot gas defrosting; the refrigeration cycle defrosting is to transfer the refrigeration system from the heating cycle to the refrigeration cycle through the four-way reversing valve, and the outdoor heat exchanger acts as a condenser to use its high-temperature refrigerant to defrost; the hot gas defrosting is By increasing the opening of the expansion valve, its throttling effect is reduced,...
