REFRIGERANT CIRCUIT

摘要

A refrigerant circuit of a supercritical cycle in which carbon dioxide is used as a refrigerant and which can hold a surplus refrigerant amount. The refrigerant circuit (10) of a refrigerating cycle in which carbon dioxide is used as a refrigerant comprises an intercooler (7) installed on the wake flow side of a condenser (3) and an intermediate pressure receiver (4) installed on the wake flow side of the intercooler (7) through a restriction mechanism (5A).
