摘要：The refrigeration system compris a refrigerant circuit (20) having a compression mechanism (30), an outdoor heat exchanger (21), an expansion mechanism (40), and an indoor heat exchanger (23), and performs vapor compression supercritical refrigeration cycle. The expansion mechanism (40) compris a first throttling mechanism (41) and a cond throttling mechanism (42) which can vary the throttling amount such that the refrigerant in the refrigerant circuit (20) is expanded in two stages. During cooling operation, target pressure value of high pressure refrigerant in the refrigerant circuit (20) is derived bad on the outlet refrigerant temperature and the inlet air temperature of the outdoor heat exchanger (21). During heating operation, target pressure value of high pressure refrigerant in the refrigerant circuit (20) is derived bad on the outlet refrigerant temperature and the inlet air temperature of the indoor heat exchanger (23). High pressure control is performed such that the pressure of high pressure refrigerant has the target value by regulating the throttling amount of the first throttling mechanism (41) or the cond throttling mechanism (42).
