Abstract (en)
The present invention is proposed to ensure a desired refrigeration capacity while observing a regulation on a filling amount of a flammable refrigerant required for a refrigeration circuit. A refrigeration circuit 34 includes a compressor CM, a condenser CD, an expansion valve EV and an evaporator EP each of which is connected by refrigerant pipes 32, and a flammable refrigerant is circulated therethrough. In the refrigeration circuit 34, volume per circuit is set equal to or smaller than 2200×10 -6 m 3 , and volume of the condenser CD is set equal to or smaller than 750×10 -6 m 3 . Thus, a filling amount of the flammable refrigerant required for one refrigeration circuit 34 can be suppressed to or below a specified value.
