ABSTRACT:
In a refrigerating cycle using a refrigerant containing hydrofluorocarbon as a main component, of a refrigerant pipe arrangement constituting the refrigerating cycle, a refrigerant pipe extending upward from a lower side to an upper side is made to have an inner diameter not larger than a value which makes the flow rate of the refrigerant be not smaller than a zero penetration flow rate. It is possible to obtain a refrigerating cycle superior in oil returning to a compressor and hence high in reliability, even in the case of using refrigerator oil having no compatibility with a refrigerant containing hydrofluorocarbon as a main component.
