Description

Defrosting and deicing device for air cooler of low-temperature refrigeration house

Technical Field

The invention relates to the technical field of air cooler defrosting, in particular to a defrosting and deicing device for an air cooler of a low-temperature refrigeration house.

Background

The air-cooler divide into refrigeration industry air-cooler and domestic air-cooler, wherein industry air-cooler generally is used for the freezer, in the cold chain commodity circulation refrigeration environment, utilize the air-cooler to produce lasting cold wind and guarantee under the freezer or the article in the cold chain commodity circulation can be in microthermal environment all the time, thereby be convenient for the save and the transportation of article, current air-cooler roughly includes the evaporimeter, the knockout, the fan, the feed liquor pipe, the muffler, water tray and shell are constituteed, its main theory of operation is when the air-cooler begins to work, liquid refrigerant gets into evaporating coil through the knockout, liquid refrigerant vaporizes and absorbs the heat in the coil pipe, the fan is then responsible for carrying out forced convection circulation with the air in freezer air-cooler and the freezer, thereby reach the purpose of freezer refrigeration, along with the live time of air-cooler increases, can frost or even freeze on the air-cooler, along with the increase of frost layer or ice layer, make the wind gap of air-cooler block up, not only can reduce the air current circulation that the air-cooler produced, lead to inside mobility is poor, still can lead to the damage of freezer because the jam problem of frost layer or ice layer, the defrosting operation and the defrosting machinery roughly divide into this defrosting structure into defrosting as follows:

the prior electric heating defrosting is to embed and install an electric heating wire in an air cooler, close the air cooler when defrosting is needed, then the electric heating defrosting structure is started to heat the electric heating wire, the heat generated by the heating of the electric heating wire can heat and melt the frost layer or the ice layer which is formed by the wind cooler, the defrosting is finished until the frost layer or the ice layer is completely melted, however, in this manner, a large portion of the heat is conducted through the air, which is very inefficient, therefore, the defrosting efficiency of the mode is low, and the defrosting process must be finished after the frost layer or the ice layer is completely melted or falls off slowly, particularly frost formed on the internal evaporator is more difficult to fall off, after defrosting is finished, the air cooler can be used after the temperature in the air cooler is reduced, the defrosting effect of the mode is further reduced, the hot air defrosting mode is the same as the hot air defrosting mode, the water spray defrosting or the mechanical and manual defrosting requires manual operation, the water spray mode requires a person standing at a high position to spray water into the air cooler by a hand-held water spray gun, and the frost layer or the ice layer is flushed by the water at normal temperature to melt the frost layer or the ice layer, although the defrosting can be rapidly carried out by the mode, but a great deal of water resource is wasted, and the bottom layer of frost cannot be quickly peeled off from the shell, if the air cooler cannot be discharged completely before being started by a large amount of water flushing, the residual water can form an ice layer again and even can freeze the fan, the service life of the air cooler is seriously influenced, the manual mechanical defrosting mode can not clean the frost layer in the air cooler well, thereby affecting the defrosting effect of the air cooler, therefore, the existing defrosting equipment and mode for the air cooler can not remove the frost layer of the air cooler well, efficiently, energy-saving and environment-friendly.

Therefore, the defrosting and deicing device for the air cooler of the low-temperature refrigeration house is provided.
