Anti-blocking device for refrigerating system

Abstract

The utility model relates to the technical field of refrigeration anti-blocking, in particular to an anti-blocking device for a refrigeration system. Comprising an electric valve, a first anti-blocking assembly and a second anti-blocking assembly, wherein the first anti-blocking assembly and the second anti-blocking assembly are used for conducting temperature returning on refrigerant oil and water separated out of a throttling component of the refrigeration equipment; the top end of the first anti-blocking assembly and the top end of the second anti-blocking assembly both communicate with a condenser air outlet pipe, the bottom end of the first anti-blocking assembly and the bottom end of the second anti-blocking assembly both communicate with an evaporator liquid inlet pipe, and the first anti-blocking assembly and the second anti-blocking assembly are connected in parallel. The electric valve is installed at the communicating position of the first anti-blocking assembly and the condenser air outlet pipe and the communicating position of the second anti-blocking assembly and the condenser air outlet pipe, and a refrigerant and the like in the condenser air outlet pipe are adjusted to flow into the evaporator liquid inlet pipe along the first anti-blocking assembly or the second anti-blocking assembly. The device is simple in structure and stable in operation, the problems of oil blockage and ice blockage caused by refrigeration oil and water and filth blockage caused by impurities in the system can be solved at the same time, and the energy consumption of the refrigeration system can be reduced.
