1. A refrigerating system, comprising:
- a refrigerating loop, comprising a compressor, a condenser, a main throttling element, and an evaporator that are connected in sequence through a pipeline;
a purification loop, comprising a purification compressor, a purification condenser, a purification throttling element, and a low-temperature separator that are connected in sequence through a pipeline, the purification loop being bi-directionally 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;
a first auxiliary flow path, of which a first end is connected with the condenser and a second end is connected with the evaporator;
when the refrigerating system runs, the purification condenser exchanging heat with the refrigerant in the refrigerating loop through the first auxiliary flow path.

Abstract
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.

22. A purification method for a refrigerating system, comprising:
-
when the refrigerating system runs, opening a first electromagnetic valve, and closing a second electromagnetic valve, wherein a refrigerant is throttled and cooled in a process of flowing through a first auxiliary flow path, exchanges heat with a purification condenser in a purification loop, and then goes back to an evaporator; and
/orwhen the refrigerating system shuts down, opening the second electromagnetic valve and a circulating pump, and closing the first electromagnetic valve, wherein the refrigerant is throttled and cooled in a process of flowing through a second auxiliary flow path, exchanges heat with the purification condenser in the purification loop, and then goes back to the evaporator. - View Dependent Claims (23, 24, 25)
