Embodiment Construction
[0011] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0012] refer to figure 1 , a variable flow hot gas defrosting mechanism for a small refrigeration system, including a compressor 1, a one-way solenoid valve 3, and an evaporator 5. The output port of the compressor 1 is connected with three or more parallel one-way solenoid valves through a gas pipe, three One end of one or more one-way solenoid valves is respectively connected to the evaporator 5 through the air pipe, without passing through the throttling device 4, directly transfers the heat of the medium to the snow and frost on the surface of the evaporator 5, thereby melting it and exchanging heat. The finished medium returns to the compressor 1 through the air...
