Description

Technical Field

[0002] Cold storage is mainly used as a constant temperature storage refrigeration equipment for food, dairy products, meat, aquatic products, etc. Cold storage is actually a low-temperature cold storage and also a kind of refrigeration equipment. Compared with refrigerators, their refrigeration area is much larger, but they have the same refrigeration principle; for large-scale fresh-keeping cold storage, they mainly store fruits, vegetables and other plant goods.

[0003] In order to keep the stored fruits and vegetables fresh, they are generally stored in a cooled state. They are still a living organism in storage. When the oxygen supply is sufficient, these living organisms perform aerobic respiration, so it is necessary to maintain a certain oxygen content inside the cold storage. When replenishing the oxygen content in the cold storage, an air inlet duct and an air outlet duct are usually installed on the cold storage, and then the air inlet duct uses an exhaust fan to transport the outside air into the cold storage.

[0004] However, when the air inlet duct inputs air into the cold storage, the air outlet duct will discharge cold air accordingly, causing the cold air inside the cold storage to leak out, which in turn causes the workload of the cold storage, making it inconvenient to exchange heat between the discharged cold air and the discharged air during gas exchange.
