Description

technical field

[0001] The invention relates to the technical field of refrigeration and quick-freezing, in particular to a heat storage defrosting system for a cold storage fan, and to a cold storage equipped with the heat storage defrosting system. Background technique

[0002] In the field of fresh-keeping storage and quick-freezing of food, due to the low temperature and high humidity conditions, the surface of the air cooler is prone to frosting. The growth of the frost layer increases the heat transfer resistance and flow resistance between the evaporator and the low-temperature environment, making it difficult to maintain the required low-temperature environment, which affects the storage quality and freshness of food. In order to maintain the low-temperature working condition of the storage space, it is necessary to Periodic defrosting is performed on the surface of the evaporator to reduce heat transfer resistance and flow resistance.

[0003] At present, most of t...
