How to control the air distribution of a small cold storage

How to better control the air distribution of a small cold storage, some friends may not understand, today okmarts.com editor will tell you!

　　To make the circulation in all warehouses as uniform as possible is a difficult and hot issue in the research of ice temperature cold storage technology. As a traditional cold storage, the air cooler is hoisted on the top of the storage body, the cold air is blown forward, and the air is returned from the back of the air cooler.

The protection structure of the ice-temperature storage here is a double-layer structure with an outer insulation structure and an inner non-insulation structure. There is an air interlayer between the inner and outer storage bodies. The air supply method is ordered and the air is returned near the bottom of the storage. , The airflow rises back to the evaporator along the air interlayer. There is a static pressure box layer under the air supply port. The airflow forms a greater pressure in the static pressure box layer, so that the air is sent down evenly into the small cold storage to form a piston flow . The speed field in the warehouse is very uniform, no dead ends occur, and the wind speed in the warehouse is very small, usually less than 0.1m/s. A small wind speed can greatly reduce the dry consumption of the fruit. After the inspection of the practice flow field in the warehouse, such air supply The arrangement method is more reasonable and can ensure the uniformity of the flow field in the reservoir.

In order to reduce the temperature fluctuation of the ice temperature storage, the most important thing for the storage protection structure is the heat storage function of the protection structure and the anti-interference function of the protection structure. This can be done by adding the thickness of the protection structure or adding an air layer. To complete, our plan for the ice-temperature warehouse is completed by adding an air interlayer. It is controlled by precision instruments, including temperature control and sensor arrangement. The temperature control accuracy selected in the small cold storage is ±0.1℃. A total of 10 sets of temperature sensors are arranged in different directions, and the data obtained are all entered into the assembly control cabinet for distinction, and then the cooler and humidifier are controlled.
