Abstract (en)
[origin: EP1873466A2] In order to regulate discharge pressure in a refrigeration cycle without using a tank for regulating a refrigerant, there is provided a refrigeration cycle in which a compressor (10), a condenser (30), a variable pressure reducer (90) and an evaporator (100) are connected in sequence by a refrigerant pipe, wherein an internal heat exchanger (60) which causes heat exchange between a refrigerant which exits from the condenser or a gas cooler (30,200) and a refrigerant which is sucked into the compressor is provided, and the discharge pressure is regulated by changing the refrigerant amount stored in the evaporator by regulating the pressure reduction amount of the variable pressure reducer. Also, it is preferable that the pressure reduction amount of the variable pressure reducer is decreased when the discharge pressure becomes a predetermined pressure or more.
