Claims

[Scope of utility model registration request]

In a refrigeration cycle in which a valve is interposed in the refrigerant pipe connecting the indoor heat exchanger and the outdoor heat exchanger, a capillary tube is installed in the middle of the refrigerant pipe connecting the indoor heat exchanger and the valve. A refrigeration cycle characterized in that a refrigerant pipe line is interposed in which a refrigerant pipe is connected in series with an expansion container having an expansion chamber formed in a diameter larger than the inner diameter of the capillary tube.
