Along with the economic and social development of China, the storage demand of a large-scale refrigeration house is continuously increased, due to the environment of low temperature and high relative humidity, an evaporation calandria of the refrigeration house is easy to frost in the refrigeration process, the frost layer can increase the thermal resistance of the evaporation calandria, the operation efficiency of a refrigeration system is reduced, and the operation energy consumption cost of the refrigeration house is increased, so that the frost layer on the surface of the evaporation calandria needs to be cleaned regularly. Common methods for treating frost include manual defrosting, hot air defrosting, water spray defrosting, electric heating defrosting, and the like.
Manual defrosting is the most original defrosting mode, and workers use long-rod cleaning tools such as brooms to clean. However, the manual defrosting for the large refrigeration house is unrealistic, an operator operates the refrigeration house by looking up, the physical consumption is high, the working time in the low-temperature environment is too long, the body health is harmed, the refrigeration house cannot be thoroughly cleaned, and the cleaned frost falls off the stored goods or the ground, so that the stored goods are polluted and the ground is wet and slippery. In addition, the evaporation tubes and fins may be deformed, and even the evaporation tubes may be damaged to cause refrigerant leakage accidents.
The hot gas defrosting is to melt the frost layer on the surface of the evaporating calandria in the cold storage by using the high-temperature superheated steam discharged by the refrigeration compressor as a heat source through an electromagnetic valve or a conversion device. At this time, the condenser of the refrigeration system is changed into an evaporator, the evaporation calandria in the refrigerator is changed into a condenser, the superheated steam of the refrigerant is condensed to release heat, and the frost layer on the surface of the calandria in the refrigerator absorbs the heat released by the refrigerant to melt the frost layer. The defects are that the defrosting time of the refrigeration house is long, the temperature of the refrigeration house is greatly influenced, and a refrigeration equipment system of the refrigeration house is too complex.
The electric heating defrosting is to heat the calandria by using electric heating pipes arranged in the evaporation calandria to melt the frost layer.
