Description

Technical Field

[0001] The utility model relates to the technical field of defrosting of refrigeration equipment, in particular to a defrosting device for refrigeration equipment. Background Art

[0002] Refrigeration equipment is a device that combines a refrigerator with a facility that uses cold energy. In refrigeration equipment, the condenser usually absorbs heat and performs heat exchange by passing cooling water through the evaporator coil. During long-term use of the evaporator coil for heat exchange, frost is likely to form on the surface of the evaporator coil, and it needs to be cleaned after frost to ensure normal use.

[0003] When the new cold storage evaporator defrosting device in the prior art is in use, the frost on the surface of the cold storage evaporator is scraped off by the deicing mechanism. However, due to the large amount of water spilled in the cold storage during the refrigeration of chilled food, a large amount of frost is easily generated on the outer surface of the evaporator. In addition, most cold storage evaporators are mainly fin-type evaporators, making it difficult for the device to remove the frost inside the evaporator, thereby affecting the practicability of the device. For this reason, we propose a refrigeration equipment defrosting device. Utility Model Content
