因此在冷庫門運行過程中，需要添加配件來保證冷庫門運行時對環境的影響，同時避免庫內低溫對冷庫門的物理狀態和功能造成負面影響，保障運行狀態和功能的穩定性。

The specifications, models and functions of the cold storage doors have been accurately calculated during the construction of the cold storage, so as to ensure that the cold storage has a good thermal insulation effect after completion. The fittings used in the manufacture of cold storage doors play an unsuccessful role in the operation of cold storage doors.
Cooling effect is closely related to air temperature. Refrigerant temperature is much higher than air temperature. Liquid refrigerant can evaporate at boiling point two when it enters the low-pressure part through expansion valve from the high-pressure part, and absorb heat in the surrounding environment at the same time. But in the high temperature season or when the cooling load is too large, it can not achieve the best cooling effect. In order to save water, water cooling towers and water circulation equipment are equipped, and cooling water is repeatedly used. The efficiency of condensation and heat absorption depends on the contact area, water temperature and flow rate between cold water and other refrigeration pipes.
Therefore, in the process of cold storage door operation, it is necessary to add accessories to ensure the impact of cold storage door operation on the environment, while avoiding the negative impact of low temperature on the physical state and function of cold storage door, and ensuring the stability of operation state and function.
