As the surface of the unit cooler in the cold storage is frosted, it hinders the conduction and dissipation of the cold capacity of the unit cooler, and ultimately affects the cooling effect. When the thickness of the frost layer on the surface of the cooler refrigeration unit reaches a certain level, the refrigeration efficiency even drops below 30%, resulting in a large waste of electric energy and shortening the service life of the refrigeration system. Therefore, it is necessary to perform cold storage defrosting operations within an appropriate period.

KITDOO independently researches and develops the thermal fluorinated cream system. Its main principle is to add a four-way valve to the compressor condensing unit, and by switching to the defrost mode, the high temperature and high pressure refrigerant from the compressor outlet is directly sent to the cold room indoor unit, and the heat of the refrigerant is used for defrosting. Similarly, the cold room indoor unit pipeline is redesigned to ensure uniform and rapid defrosting.

The advantages of this defrosting method are obvious:

1, defrosting uniform, every copper tube can defrost.

2, defrosting speed, This kind of cold room cooler refrigeration unit defrosting only 8 minutes, ordinary electric heating tube defrosting needs 30 minutes.

3. Cold storage temperature is stable. The temperature of hot fluoride frost cooler refrigeration unit changes about 5 degrees Celsius when defrosting, and the maximum temperature of the ordinary cold room cooling rises nearly 18 degrees Celsius.

4. Less power consumption. The hot fluoride frost cooler refrigeration units use the same amount of electricity as normal refrigeration when defrosting. The power of the electric heating tube used in defrosting of common cold room cooling units reaches 5KW, which is 2 times higher than that of normal refrigeration.

KITDOO has completed several cold storage projects for hot fluorinated frost. Customers are quite satisfied with this.
