[0002] Cold storage is mainly used as constant temperature storage refrigeration equipment for food, dairy products, meat, aquatic products, chemicals, medicine, seedling cultivation, scientific experiments, etc. Generally, cold storage is cooled by refrigeration mechanism, using liquid with very low vaporization temperature as coolant, making it evaporate under low pressure and mechanical control conditions, absorbing heat in the storage, so as to achieve the purpose of cooling. In order to ensure the flow and ventilation of gas in the storage, a ventilation structure with temperature control of the cold storage is usually set inside the cold storage.

[0003] When the cold storage temperature-controlled ventilation structure is ventilated, the low-temperature air in the storage is discharged outside the storage, and the high-temperature fresh air outside the storage is sent into the storage. The exchange of cold air in the storage and the outside air also generates heat exchange, causing "heat leakage" and wasting energy. Therefore, a cold storage temperature-controlled ventilation structure is proposed to address the above problems. Utility Model Content
