A heat pump air conditioning system includes: a compressor; a first heat exchanger; a first refrigerant flow path provided with a first expansion valve and a second heat exchanger; the second refrigerant flow path is provided with a first electromagnetic valve; the third refrigerant flow path is provided with a second electromagnetic valve; a fourth refrigerant flow path provided with a second expansion valve and a third heat exchanger; a fifth refrigerant flow path provided with a third expansion valve and a fourth heat exchanger; and a liquid storage tank; the control part is used for controlling at least any one of the first expansion valve, the second expansion valve, the first electromagnetic valve and the second electromagnetic valve to operate a plurality of different heating modes; in various different heating modes, the control part compares a waste heat recovery characterization value of the heat pump air conditioning system with a first threshold value and a second threshold value larger than the first threshold value, and when the waste heat recovery function is closed, the waste heat recovery function is started only when the waste heat recovery characterization value is larger than the second threshold value. When the waste heat recovery function is started, the waste heat recovery function is closed only when the waste heat recovery characterization value is smaller than the first threshold value.

    一种热泵空调系统,包括:压缩机;第一热交换器;设有第一膨胀阀和第二热交换器的冷媒第一流路;设有第一电磁阀的冷媒第二流路;设有第二电磁阀的冷媒第三流路;设有第二膨胀阀和第三热交换器的冷媒第四流路;设有第三膨胀阀和第四热交换器的冷媒第五流路;和储液罐;还设有控制部,控制部控制第一至第二膨胀阀和第一至第二电磁阀中的至少任意一方来运行多种不同的制热模式;在多种不同的制热模式下,控制部将热泵空调系统的废热回收表征值与第一阈值及大于该第一阈值的第二阈值进行比较,在废热回收功能关闭时仅当废热回收表征值大于第二阈值时才开启废热回收功能,在废热回收功能开启时仅当废热回收表征值小于第一阈值时才关闭废热回收功能。
