Heat pump air conditioning device sharing outdoor air side heat exchangers

The invention relates to a heat pump air conditioning device sharing outdoor air side heat exchangers. The heat pump air conditioning device comprises a plurality of modular heat pump air conditioningunits; and each modular heat pump air conditioning unit comprises a compressor, a throttling valve, a four-way reversing valve, an indoor side heat exchanger, a fan, a refrigerant decompression storage tank, a refrigerant supplementing storage tank and at least one outdoor side air heat exchanger, wherein the outdoor side air heat exchangers in each modular heat pump air conditioning unit are connected in parallel through pipelines. The heat pump air conditioning device has the advantages that the outdoor air side heat exchangers can be shared by a plurality of parallel heat pump air conditioning devices, all the outdoor air side heat exchangers can be fully utilized, and the operation efficiency of heat pump air conditioners can be greatly improved. 本发明涉及种共享室外空气侧换热器的热泵空调装置，该热泵空调装置包括有多个模块式热泵空调机组，每个模块式热泵空调机组包括有压缩机
