Description

Refrigerator auxiliary device for preventing ice particles led out by throttling and cooling from causing blockage

Technical Field

The invention relates to the technical field of refrigerating machines, in particular to an auxiliary device of a refrigerating machine, which avoids blockage caused by ice particles led out by throttling and cooling.

Background

The refrigerator transfers the heat of a cooled object with a lower temperature to an environment medium so as to obtain cold, and some unstable factors often occur in the use process of the refrigerator, so that the refrigerator also needs to be checked and maintained.

Most of the ice blockage occurs on the expansion valve because the refrigerant contains water, and when the refrigerant passes through the expansion valve, the water is analyzed out and is frozen into ice particles due to throttling and temperature reduction, and the valve hole of the expansion valve is partially or completely blocked. After the ice is blocked, the refrigerating capacity is reduced because the refrigerant flow is sharply reduced, the evaporator and the return air pipe frost layer are soft, and the temperature of the storage cannot be reduced.
