Double-working-condition air energy high-temperature heat pump water heater device

The utility model discloses a double-working-condition air energy high-temperature heat pump water heater device which comprises a variable-frequency air supplementing compressor, a four-way valve, auser side domestic hot water heat exchanger, a user side heating heat exchanger, a first electronic expansion valve, a vapor-liquid separator, a second electronic expansion valve, an economizer, a third electronic expansion valve and an electromagnetic valve. The air energy heat pump hot water unit mainly solves the problems that in a low-temperature environment, the heating capacity of a common air energy heat pump hot water unit is sharply reduced, and the outlet water temperature is not high. The air energy heat pump hot water unit has the advantages of being simple in structure, high in working efficiency and energy utilization efficiency, capable of achieving broadband operation and the like. 本实用新型公开了一种双工况空气能高温热泵热水机装置，包括变频补气压缩机、四通阀、用户侧生活热水换热器、用户侧采暖换热器、第一电子膨胀阀、汽液分离器、第二电子膨胀阀、经济器、第三电子膨胀阀和电磁阀。本实用新型主要解决了低温环境下，普通空气
