Abstract (en)
A refrigeration apparatus includes a main compression mechanism, a gas cooler, a main throttle mechanism, and an evaporator, and allows circulation of a refrigerant containing carbon dioxide. The refrigeration apparatus includes a split heat exchanger including a first flow channel and a second flow channel, in which the first flow channel is disposed at a site downstream of the gas cooler and upstream of the main throttle mechanism, and part of a refrigerant flowing out of the first flow channel flows into the second flow channel; an auxiliary throttle mechanism that throttles a refrigerant that is to flow into the second flow channel; and an ejector including a nozzle and a suction part, in which the nozzle is disposed at a site downstream of the main compression mechanism and upstream of the first flow channel, and the suction part sucks in a refrigerant flowing out of the second flow channel.
