The present invention provides a refrigerating system, including: a refrigerating loop (100), including a compressor (190), a condenser (110), a main throttling element (180), and an evaporator (120) that are connected in sequence through a pipeline; and a purification loop (200), including a purification compressor (210), a purification condenser (220), a purification throttling element (240), and a low-temperature separator (230) that are connected in sequence through a pipeline, the purification loop being bidirectionally connected to the refrigerating loop through the low temperature separator and configured to separate a non-condensable gas in the refrigerating loop; wherein the purification condenser is capable of exchanging heat with a refrigerant in the refrigerating loop. Thus, efficient and reliable separation of the refrigerant and the non-condensable gas is achieved. |
