Technical field
This utility model is related to a kind of defrosting system, belongs to refrigeration technology field.
Background technology
Existing defrosting system probably has three kinds at present, and a kind of is aqueous fusion defrosting system, with water heat exchanger be rinsed with
Reach the purpose of defrosting, this kind of system can expend substantial amounts of water；Another kind, using electric defrosting system, increases electricity in heat exchanger and adds
Heat, when needing defrosting, to electrical heating electrified regulation to reach the purpose of defrosting, the substantial amounts of electric energy of this kind of system consumption, does not save
Energy；The third is defrosting system by superheated vapour, needs changing of defrosting by bypassing the steam entrance of the High Temperature High Pressure that a road compressor is discharged
Carry out defrosting, this kind of mode energy-conservation, existing defrosting system by superheated vapour needs to increase defrosting conciliation station and discharge opeing bucket, unfavorable in hot device
In miniaturization, unit, investment increasing, pipeline and complex operation.
Utility model content
This utility model is directed to the deficiency that existing defrosting system exists, and provides a kind of defrosting system.
The technical scheme that this utility model solves above-mentioned technical problem is as follows：
A kind of defrosting system, including compressor, gas-liquid separator and some groups of heat exchangers it is characterised in that described compression
The air entry of machine is connected with the outlet of gas-liquid separator, and some branch roads and heat exchanger are passed through in the import of described gas-liquid separator
Outlet is connected, and the branch road between described heat exchanger and gas-liquid separator is additionally provided with return-air electromagnetic valve, the entering of described heat exchanger
It is connected with Liang Ge branch at mouthful, a branch is connected with check valve, another branch is connected with expansion near heat exchanger side
Valve, the opposite side of described expansion valve is connected with liquid supply electromagnetic valve, is connected by pipeline between described liquid supply electromagnetic valve, described list
Connected to the expansion valve and liquid supply electromagnetic valve of adjacent legs to the other end of valve by pipeline, described heat exchanger another
Side is connected with defrosting electromagnetic valve, and the other end of defrosting electromagnetic valve is connected after being merged by pipeline to the air vent of compressor.

Specific embodiment
Below in conjunction with example, principle of the present utility model and feature are described, example is served only for explaining this practicality
New, it is not intended to limit scope of the present utility model.
A kind of defrosting system, including compressor 1, gas-liquid separator 2 and 3 groups of heat exchangers 7, the air entry of compressor and gas-liquid
The outlet of separator is connected, and the import of gas-liquid separator is connected with the outlet 7-1 of heat exchanger by some branch roads, heat exchanger
Return-air electromagnetic valve 3 is additionally provided with the branch road and gas-liquid separator between, the entrance of heat exchanger is connected with Liang Ge branch, one point
Prop up and be connected with check valve 6, another branch is connected with expansion valve 4 near heat exchanger side, the opposite side of expansion valve is connected with
Liquid supply electromagnetic valve 5, is connected by pipeline between liquid supply electromagnetic valve, and the other end of check valve is connected to adjacent legs by pipeline
Expansion valve and liquid supply electromagnetic valve between, the opposite side of heat exchanger is connected with defrosting electromagnetic valve 8, and the other end of defrosting electromagnetic valve leads to
Cross and connect after pipeline merges to the air vent of compressor, described heat exchanger is finned heat exchanger.
The work process of above-mentioned defrosting system is as follows：
When certain group is detected finned heat exchanger frosting be more need defrosting when, return-air electromagnetic valve 3, supply liquid electromagnetic
Valve 5 cuts out, and defrosting electromagnetic valve 8 is opened, and the refrigerant gas of the High Temperature High Pressure that compressor 1 is discharged are entered by finned heat exchanger
Mouthful 7-2 enters and carries out defrosting to fin, the refrigerant liquid simultaneously cooling down pass through finned heat exchanger outlet 7-1, check valve 6 and
Enter finned heat exchanger heat absorption evaporation after expansion valve 4 throttling of adjacent legs to be siphoned away by compressor 1, complete to circulate, to be detected
To finned heat exchanger defrosting complete when, defrosting closed electromagnetic valve, return-air electromagnetic valve, liquid supply electromagnetic valve are opened one by one, now should
Group finned heat exchanger whole defrosting process terminates.When next group heat exchanger is detected and needing defrosting, then carry out a defrosting
Process.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within new spirit and principle, any modification, equivalent substitution and improvement made etc., should be included in guarantor of the present utility model
Within the scope of shield.
