Abstract
The utility model discloses a counter-circulating defroster for refrigerating equipment which consists of a compressor, a dual-pressure control valve, an evaporator, a condenser, a four-communicating reversing valve, a liquid receiver, a gas-liquid separator, a liquid-inspection mirror, a liquid-division device and a valve. The dual-pressure control valve, the evaporator, the condenser, the four-communicating reversing valve, the liquid receiver, the gas-liquid separator, the liquid-inspection mirror, the liquid-division device and the valve are connected with the compressor through pipelines. Compared with the prior art, the reverse-cycled defrost device of the refrigeration equipment has the advantages of reasonable design, high refrigeration efficiency, reliable operation, energy saving, automatic defrosting, fast defrosting, convenient installation and operation, long service life and so on. Therefore, the utility model has good promotion value.
Description
1, technical field
The utility model relates to a kind of Refrigeration Technique, specifically a kind of refrigeration plant reverse cycle defrosting device.
2, technical background is in the refrigeration plant of prior art, and Defrost method adopts electric defrosting more, and the deficiency of its existence is to waste a large amount of electric energy, and the Artificial Control batch (-type) carries out, and brings very big inconvenience to operating personnel.
3, summary of the invention
The purpose of this utility model provides a kind of four-way change-over valve that utilizes the refrigeration plant reverse cycle defrosting device that allows evaporimeter and condenser alternation that the frosting in the refrigerating chamber is dissolved is flowed in the working media commutation.
The purpose of this utility model realizes in the following manner, with the pipeline of compressor in four-way change-over valve, liquid reservoir, liquid-sighting glass and valve is set refrigerant is controlled automatically the operating efficiency and the service life of improving refrigeration machine.
Accompanying drawing is the structural representation of refrigeration plant reverse cycle defrosting device.
4, description of drawings
Below with reference to Figure of description counter-circulating defroster for refrigerating equipment of the present utility model being done at length Explanation.
Counter-circulating defroster for refrigerating equipment of the present utility model, its structure are by compressor 1, double pressure-controlled Valve 3 processed, evaporimeter 6, condenser 22, four-way change-over valve 4, liquid reservoir 16, gas-liquid separator 2, look liquid Mirror 12, knockout 21 and valve consist of, double pressure-controlled valve 3 processed, evaporimeter 6, condenser 22, four-way commutation Valve 4 liquid reservoirs 16, gas-liquid separator 2, liquid-sighting glass 12, knockout 21 and valve are by pipeline and compressor 1 links together.
Air inlet, the gas outlet phase of double pressure-controlled valve 3 processed and compressor 1 also connects, the air inlet of compressor 1 with The interface 4 of four-way change-over valve 4 joins, gas outlet serial connection gas-liquid separator 2 and the four-way change-over valve of compressor 1 4 interface 2 joins, and the interface of four-way change-over valve 41 serial connection evaporimeter 6, defrosting temperature-sensing valve 7, evaporimeter are swollen Swollen valve 8, feed flow check valve 10, carriage triple valve 11, liquid-sighting glass 12, device for drying and filtering 13 and liquid valve 14 join the outlet string liquid feed valve 17 of liquid reservoir 16, check valve 19, condenser with the import of liquid reservoir 16 22 join with the interface 3 of four-way change-over valve 4, defrosting bypass pipe 18 string defrosting expansion valves 20 through knockout 21 with Condenser 22 joins, at the two ends of evaporator expansion valve 8 and be connected to check valve 9.
5, its processing and fabricating of embodiment refrigeration plant reverse cycle defrosting of the present utility model device is very simple and convenient, connects shown in the by specification accompanying drawing to get final product, and the parts in the equipment are employed universal accessories in the refrigeration plant.Electric apparatus control apparatus is original refrigeration plant middle controller.
Counter-circulating defroster for refrigerating equipment of the present utility model is compared with existing technology, and has design and closes Reason, refrigerating efficiency height, reliable, energy savings, automatic defrosting, defrosting speed be fast, install and use The characteristics such as convenience, long service life, thereby, have good value for applications.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
