Ice house high-efficiency electric-heating defrosting device and use method

Abstract

Disclosed are an efficient electric defrost device for a refrigerator, and a method thereof, belonging to the defrost field. In the device, a compressor, an oil separator, a condenser, a filter and a regenerator are connected in sequence through pipe flanges, and the regenerator is then connected with the compressor through a pipe flange; the regenerator, a solenoid valve, an expansion valve and a coil pipe are connected through pipe thread; the coil pipe is connected with a gas collecting pipe through welding; the gas collecting pipe is connected with the regenerator through a pipe flange; the gas collecting pipe is bound with a temperature controller; fins are inserted in the coil pipe and an electric heating pipe; a return air door is arranged on an enclosure box; a blower, the coil pipe, the fins, the electric heating pipe, the gas collecting pipe, the temperature controller and a temperature bulb B are arranged inside the enclosure box which is connected with a water discharge pipe through thread; and the electric heating pipe, the temperature controller, a controller, a protector and the solenoid valve are electrically connected. The method comprises the following steps: the device jumps off at 8 DEG C and gets resetted at 3 DEG C; the solenoid valve is closed in the refrigeration and defrost delay time, then the blower stops, while the compressor and the condenser start to work; the refrigerant enters into the condenser for cold storage; the return air door is closed; the electric heating pipe is electrified for defrosting in a set defrost time; the water discharge time is set; and the return air door is opened for refrigeration. The device is used for defrosting, which is energy-saving and highly efficient.

Description

technical field [0001] The invention relates to a high-efficiency electric defrosting device for a cold storage and a method for using it, and relates to the technical field of refrigeration equipment; in particular, it relates to the technical field of refrigeration equipment for a cold storage; in particular, it relates to the technical field of implementing defrosting for a cold storage by means of electric heating; in particular, it relates to a high-efficiency electric heating defrosting device for a cold storage and Method of use technical field. Background technique [0002] For cold storage, there are low-temperature storage, medium-temperature storage, high-temperature storage, and low-temperature drying storage for special purposes such as germplasm storage, precious books, film and cultural relic storage; no matter what kind of cold storage, there is a problem of defrosting, that is to say It is necessary to remove the frost layer on the evaporator of the refriger...

AI Technical Summary

Problems solved by technology

[0003] As far as defrosting is concerned, there are several different defrosting methods, such as hot air defrosting, hot ammonia defrosting, hot fluorine defrosting, water defrosting, etc., and these defrosting methods will not be described here; In addition to the above-mentioned defrosting methods, there is also a conventional electric defrosting, which has the disadvantages of low efficiency, large energy consumption, and the heat and water vapor generated during defrosting are easily Infiltration into the cold storage increases the temperature and humidity of the cold storage (that is, destroys the temperature and humidity environment that the cold storage should maintain), affects the storage quality in the cold storage, increases the power consumption of the refrigeration unit, unreasonable defrosting structure, and cannot fully utilize energy.
