The outdoor unit of cold storage is an important part of the refrigeration system, which is exposed to the outdoor environment for a long time. Inadequate sunshade and rain protection measures are core hidden dangers that are easy to be ignored but affect equipment operation, directly related to the service life of the outdoor unit and the overall operational stability of the unit.

         Inadequate sunshade will cause the outdoor unit to be exposed to intense sunlight for a long time, leading to a sharp rise in the body temperature, reducing heat dissipation efficiency, increasing the operating load of the compressor, not only increasing energy consumption, but also accelerating the aging of electrical components, laying hidden dangers of failures and affecting the refrigeration effect.

         Inadequate rain protection will make rainwater easily seep into the interior of the outdoor unit, eroding electrical components, pipeline interfaces and welding parts, leading to component rust, short circuit, and even refrigerant leakage, causing unit failure and shutdown, and greatly increasing maintenance costs.

         Sunshade and rain protection are basic protections for outdoor units. Inadequate protection will induce a series of chain problems. It is necessary to standardize the setting of sunshade and rain protection facilities, avoid the outdoor unit being exposed to sunlight and rain, regularly check the integrity of the protection facilities, and timely maintain and repair them, laying a solid protective barrier for the stable operation of the outdoor unit and ensuring the normal refrigeration of the cold storage unit.
