The cold storage board is a special building used for freezing and cold storage of food and keeping a certain low temperature. The floor, wall and roof are covered with a certain thickness of moisture-proof layer and insulation layer to reduce the introduction of external heat. At the same time, for To reduce the absorbed radiant heat, the outer wall surface of the cold storage board is generally painted white or light color.
The method of energy saving and reduction of cold storage board:
一. The cold storage door should be closed tightly and not run cold, and the cold consumption of the cold storage door should be reduced from the following aspects:
1. Effectively maintain the refrigerated door to ensure trouble-free opening and closing of the refrigerated door, regularly check the performance of the sealing strip and the heating wire, handle ice, frost, and water at any time, maintain the tightness of the refrigerated door, and prevent transportation vehicles from colliding with the door.
2. Minimize the number of door openings and opening time as much as possible, so that the door can be closed at hand when entering and exiting.
3. Add a cotton curtain or PVC soft curtain on the inside of the door.
4. Set up a high-efficiency air curtain on the outside of the warehouse door, and ensure that it is installed correctly and operates normally.
二. Warehouse lighting control
Warehouse lighting not only consumes electric energy, but also increases the heat in the warehouse. Therefore, warehouse lighting should be controlled in groups of front, middle and rear. After entering the warehouse, the staff should minimize the number and time of turning on the lights, and make sure that the lights are turned off when people go.
三. Minimize the number of people entering the warehouse and the time in the warehouse
The staff in the warehouse will continuously release heat and increase the heat load. Therefore, the operators and operation time in the warehouse should be minimized, and those who can not operate in the warehouse should not be in the warehouse as much as possible.
四. Reasonably reduce the number and time of fan opening
The operation of the axial fan on the cooler in the warehouse will generate heat. From the perspective of energy saving, the start-up time and the number of start-ups should be reduced as much as possible. However, in the actual fruit and vegetable storage, the operation method that is economical and guarantees the product quality is: just warehousing In order to ensure rapid cooling, all the axial fans are turned on. After the storage temperature is stabilized, the number of openings will be reduced, and the temperature requirements are strictly required for storage. Running.
五、Reasonable stacking. Improve warehouse utilization
The rate of the warehouse directly affects the economic benefits of the cold storage board. The utilization rate is low, the cold consumption per unit weight of goods increases, and the dry consumption increases, and the cost increases. Therefore, strong packaging, shelves, etc., should be used as high as possible to improve the utilization of the warehouse. When the goods are dissatisfied, if the storage characteristics of the goods are the same or similar without affecting each other, they can be mixed for a short time.
六. Ventilation operation
Fruits and vegetables are still living organisms after harvest, and they are constantly metabolized during storage. Therefore, the cold storage panels for storing fruits and vegetables need to be ventilated regularly. Ventilation is to introduce fresh air from the outside of the warehouse to discharge the dirty air in the warehouse. When the outside temperature is high, energy loss is great. Therefore, the ventilation operation should be carried out when the temperature is close to the warehouse temperature. The number of ventilation and the time of each ventilation should be determined according to the type and requirements of the stored goods.
