    Why is frost in the cold storage in summer? What is the purpose of defrosting?
    Author: Shan County Hengsheng Refrigeration Engineering Co., Ltd. Published: 2019-12-06 09:40:55

    Due to the frost on the surface of the evaporator in the cold storage, it prevents the transmission and dissipation of the cold quantity of the refrigeration evaporator (pipe), which affects the cooling effect.

    When the thickness of the frost layer (ice layer) on the surface of the evaporator reaches a certain level, the cooling efficiency even drops below 30%, resulting in a large waste of electrical energy and shortening the service life of the refrigeration system. Therefore, it is necessary to perform the defrost operation of the cold storage in an appropriate period.

    Defrosting purpose:

    1. Improve system cooling efficiency;

    2. Guarantee the frozen quality in the warehouse;

    3. Save electricity;

    4. Extend the service life of the cold storage system.
