Abstract

The invention discloses a quick defrosting device for an air conditioner evaporator. The quick defrosting device comprises a compressor, a condenser, an evaporator, a solenoid valve and a three-way pipe. An outlet of the compressor is connected with the inlet end of the three-way pipe. One outlet end of the three-way pipe is sequentially connected with the condenser and the evaporator and then is connected into an inlet of the compressor, and the other outlet end of the three-way pipe is connected with the solenoid valve and then is connected into a pipeline between the condenser and the evaporator. A coil pipe of the evaporator is provided with a temperature sensor. The temperature sensor is electrically connected with the solenoid valve through an air conditioner control system. The quick defrosting device is small in occupied space, small in weight, convenient to mount, simple in structure, easy to manufacture, safe, reliable, capable of rapidly melting a great amount of frost or ice formed on the surface of the evaporator and solving the problem that the frost on the surface of the evaporator is not prone to being removed in the refrigeration process of an air conditioner in the low-temperature environment, free of consuming other energy, environment-friendly, and capable of being widely applied to various types of air conditioners needing to conduct refrigeration in the low-temperature environment.

Description

A/C evaporator quick defrosting apparatus
Technical field
The present invention relates to military air-conditioning equipment field, specifically a kind of A/C evaporator quick defrosting apparatus.
Background technology
Military air-conditioning equipment environment for use is severe, requires can normally work in the ambient temperature range of-45 DEG C ~ 55 DEG C.For the heat-producing device in confined space provides temperature controlled air-conditioning equipment, even need in environment temperature lower than still refrigeration work when 10 DEG C, under this state, the evaporating temperature of air-conditioning equipment is lower than 0 DEG C, and evaporator surface very easily frosting is even icing.And existing Defrost method or too slow or consumption electric energy, the Special use requirement of military air-conditioning equipment can not be met completely.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, provide a kind of structure A/C evaporator quick defrosting apparatus that is simple, that easily implement, can be good at solving the problem of the air-conditioning equipment evaporator surface quickly defrosting of refrigeration work at low ambient temperatures.
Technical scheme of the present invention is as follows:
A kind of A/C evaporator quick defrosting apparatus, include compressor reducer, condenser, evaporimeter, magnetic valve and three-way pipe, it is characterized in that: the outlet of described compressor reducer is connected by the entrance point of pipeline with described three-way pipe, after the port of export of described three-way pipe is connected with described condenser, evaporimeter successively by pipeline, access the import of described compressor reducer, after another port of export of three-way pipe is connected with described magnetic valve by pipeline, access the pipeline between described condenser and evaporimeter; The coil pipe of described evaporimeter is provided with temperature sensor, and described temperature sensor is electrically connected with described magnetic valve by air-conditioner control system.
Described A/C evaporator quick defrosting apparatus, is characterized in that: be connected with filter and liquid valve in the pipeline between described condenser and evaporimeter in turn.
Described A/C evaporator quick defrosting apparatus, is characterized in that: be connected with steam valve in the pipeline between described evaporimeter and compressor.
Military air-conditioning equipment environment for use is severe, requires can normally work in the ambient temperature range of-45 DEG C ~ 55 DEG C.For the heat-producing device in confined space provides temperature controlled air-conditioning equipment, even need in environment temperature lower than still refrigeration work when 10 DEG C, under this state, the evaporating temperature of air-conditioning equipment is lower than 0 DEG C, and evaporator surface very easily frosting is even icing.
The present invention is when the frosting of air-conditioning equipment evaporator surface (now air-conditioner control system experiences evaporator coil temperature lower than-5 DEG C), magnetic valve on bypass line is opened, the part high-temperature gas that compressor of air conditioner is discharged gets around condenser by bypass line and directly sends in evaporimeter, utilizes high temperature rapid frost melting; When evaporator coil temperature returns to higher than-5 DEG C, the closed electromagnetic valve on bypass line, air-conditioning equipment recovers normal refrigerating operaton.
Beneficial effect of the present invention:
1, the present invention can fall a large amount of frosting of evaporator surface or freezes by fast melt, effectively solve air-conditioning equipment at low ambient temperatures refrigeration work time evaporator surface a large amount of frosting not easy-clear problem.
2, the present invention utilizes the high-temperature gas of air-conditioning equipment itself to defrost, without the need to consuming other energy, environmental protection.
3, the present invention takes up room little, lightweight, easy for installation, and structure is simple, be easy to manufacture, safe and reliable.
4, the present invention is applied widely, can be widely used in the air-conditioning equipment of all kinds of needs refrigeration work at low ambient temperatures.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
See Fig. 1, a kind of A/C evaporator quick defrosting apparatus, include compressor reducer 1, condenser 2, evaporimeter 3, magnetic valve 4 and three-way pipe 5, the outlet of compressor reducer 1 is connected by the entrance point of pipeline with three-way pipe 5, after the port of export of three-way pipe 5 is connected with condenser 2, evaporimeter 3 successively by pipeline, the import of access compressor reducer 1, after another port of export of three-way pipe 5 is connected with magnetic valve 4 by pipeline, accesses the pipeline between condenser 2 and evaporimeter 3; The coil pipe of evaporimeter 3 is provided with temperature sensor, and temperature sensor is electrically connected with magnetic valve 4 by air-conditioner control system.
In the present invention, in the pipeline between condenser 2 and evaporimeter 3, be connected with filter 6 and liquid valve 7 in turn.
Steam valve 8 is connected with in pipeline between evaporimeter 3 and compressor 1.
Below in conjunction with accompanying drawing, the present invention is further illustrated:
The present invention compressor 1 gas exhaust piping and enter evaporimeter 3 pipeline on be provided with three-way pipe 5, weld one section of bypass line by three-way pipe 5 to be connected with normally closed solenoid valve 4, mounting temperature sensor on the coil pipe of evaporimeter 3, by the unlatching of air-conditioner control system Controlling solenoid valve.When the temperature that evaporimeter 3 coil pipe experienced by temperature sensor is lower than-5 DEG C, control system Controlling solenoid valve 4 is opened, and the part high-temperature gas that compressor 1 is discharged gets around condenser 2 by bypass line and directly sends in evaporimeter 3, utilizes high temperature rapid frost melting; When temperature sensor experiences the temperature return of evaporimeter 3 coil pipe to during higher than-5 DEG C, control system Controlling solenoid valve 4 is closed, and air-conditioning equipment recovers normal refrigerating mode.
