Description

Technical Field

[0001] The utility model relates to the technical field of cold storage for fruits and vegetables, in particular to a cold storage ventilation device for storing and preserving fruits and vegetables. Background Art

[0002] Fruit and vegetable cold storage is also called vegetable cold storage, which is a warehouse that uses cooling facilities to create suitable humidity and low temperature conditions. Also known as cold storage, it is a place for processing and storing agricultural and livestock products. It can get rid of the influence of climate and extend the storage and preservation period of agricultural and livestock products to regulate market supply. Fruit and vegetable cold storage is a building that uses artificial refrigeration to make a fixed space reach the specified temperature for the convenience of storing items. When storing fruit and vegetable cold storage, the air inside the cold storage needs to be ventilated to ensure air circulation.

[0003] The existing fruit and vegetable cold storage storage and preservation ventilation device uses a negative pressure fan to extract the cold storage air and discharge it to the outside. The refrigeration fan cools the air and then replenishes the air inside the cold storage. The negative pressure fan extracts the internal air and directly discharges it, which is easy to pollute the external air and affect the working environment.

[0004] Therefore, a ventilation device for storing and preserving fruits and vegetables in a cold storage is proposed. Utility Model Content
