REFRIGERATING SYSTEM AND METHOD FOR OPERATING THE SAME

摘要

A refrigerating system (2) according to the invention comprises a refrigerating cycle having a compressor (4), a condenser (6), a collecting container (10), an expansion device (16), an evaporator (18) and refrigerating circuits circulating a refrigerant therethrough; a by-pass line (20) comprising a by-pass valve (22), the by-pass line (20) connecting the gas space of the collecting container (10) with the suction line of the compressor (4); and a control unit that in operation allows switching between normal operation of the refrigerating cycle and refrigerant collecting operation in which the by-pass valve (22) is open and reduces the liquefying pressure in the condenser (6) such that the remaining liquid refrigerant in the condenser (6) is evaporated and led into the collecting container (10).
