Description

Cold storage air cooler steam defrosting device

Technical Field

The utility model relates to the technical field of refrigeration house cooling equipment, in particular to a refrigeration house air cooler steam defrosting device.

Background

The refrigeration house cooling equipment is divided into two parts, one is a compressor arranged outdoors, the other is an air cooler arranged indoors, and the compressor compresses refrigerant into high-pressure saturated gas (Freon) which is gaseous refrigerant, and the gaseous refrigerant is condensed by a condenser. After being throttled by the throttling device, the air is introduced into the evaporator to cool and exchange heat with the medium to be cooled. For example, the evaporator is connected to the cold storage, the serpentine tube in the evaporator exchanges heat with air, and then the cold air is blown into the cold storage by blowing. In the process, the evaporator absorbs moisture, the surface of the evaporator is frosted, gaps of blades of the evaporator are blocked, and then the fan cannot work.

The traditional defrosting methods at present comprise hot gas defrosting (hot gas defrosting) water defrosting, electric heating tube defrosting and manual defrosting.

Electric heating defrosting: the electrothermal defrosting is to utilize the electric heating pipes arranged in the air cooler to heat the fins so as to melt the frost layer. The method has simple system and more convenient operation, but the air cooler is matched with an electric heating pipe with the heat exchange area of 40-100W per square, has great influence on fluctuation of the warehouse temperature and does not save energy, and has the defects that: the power consumption is large, the service life of the heating pipe is short, and the heating pipe has potential safety hazards, and particularly the explosion-proof refrigeration house cannot be used.

Hot fluorine defrosting: the hot working medium defrosting is to utilize superheated refrigerant steam with higher temperature discharged by a compressor, enter an evaporator after passing through an oil separator, temporarily serve the evaporator as a condenser, and utilize heat released during condensation of the hot working medium to melt a frost layer on the surface of the evaporator. Meanwhile, the refrigerant and lubricating oil originally stored in the evaporator are pressurized by means of a hot working medium or discharged into a defrosting liquid discharging barrel or a low-pressure circulating barrel by gravity. When the hot gas is defrosted, the load of the condenser is reduced, and partial electric energy can be saved during the operation of the condenser. The defects are as follows: high installation cost and short service life.

Defrosting by water: the water defrosting is a method of spraying water to the outer surface of the evaporator by using a water pump or a water spraying device so that the frost layer is melted by the heat of the water and washed away. The water defrosting operation is simple, the time is short, and the method is a very effective defrosting method. The defects are as follows: in a refrigerator with low temperature, repeated defrosting is carried out, and the water temperature is too low, so that the defrosting effect is affected; if the frost is not flushed out within a set time, the frost layer may become an ice layer after the air cooler works normally, so that the next defrosting is more difficult. Some ice in the air cooler cannot be melted at all, and even the fan blade of the air cooler is stuck and burnt out. The installation is troublesome, especially is not suitable for extreme weather in north.
