Embodiment 1
[0016] Example 1: Two-stage series connection of large temperature difference compression heat pump unit
[0017] As shown in Figure 1, the heat pump unit has a first-stage evaporator 2a, a first-stage compressor 3a, a first-stage condenser 1a, a first-stage condenser outlet refrigerant throttling device 4a, and a first-stage evaporator outlet The refrigerant throttling device 5a is composed of the second-stage evaporator 2b, the second-stage compressor 3b, the second-stage condenser 1b, and the second-stage condenser outlet refrigerant throttling device 4b. The pressure of the first-stage condenser 1a is greater than the pressure of the second-stage condenser 1b, the pressure of the second-stage condenser 1b is greater than the pressure of the first-stage evaporator 2a, and the pressure of the first-stage evaporator 2a is greater than the pressure of the second-stage evaporator 2b. The superheated or saturated refrigerant vapor from the first-stage evaporator 2a is compressed...
