Abstract

A refrigerating apparatus comprising a refrigerant return mechanism (5) for returning a liquid refrigerant in a receiver (17) to a circulation route. Accordingly, the liquid refrigerant in the receiver (17) can be forcibly returned to the circulation route in such an operating state that the circulation route for the refrigerant is formed to return the refrigerant fed from compression mechanisms (11D, 11E) from a second use side unit (20) to the compression mechanisms (11D, 11E) through first use side units (30, 40).
