Supplementary cryogenic warehouse refers to a kind of cryogenic warehouse that is renovated or added to an existing building. The main focus of the standard is to ensure the environmental parameters such as temperature, humidity and air circulation in the cryogenic warehouse to ensure the quality and shelf life of the goods in the warehouse.
Here are some of the main criteria for the construction of back-up cryogenic warehouses:
1. Temperature standard: The design temperature of low-temperature warehouses is generally between -25°C and -18°C. High tightness requirements to ensure temperature stability.
2. Thermal insulation materials: The walls, roofs and floors of low-temperature warehouses should be made of excellent thermal insulation materials, such as insulation boards, polyurethane, etc., to reduce energy loss.
3. Cooling system: A reliable cooling system needs to be installed in the low-temperature warehouse, including refrigeration units, evaporators, refrigeration fans, etc., to maintain a stable low temperature in the warehouse.
4. Control system: Cryogenic warehouses need to install monitoring and control systems for parameters such as temperature, humidity and air circulation to ensure accurate control of environmental conditions.
5. Load: The design load of the low-temperature warehouse should be determined according to the type and quantity of goods stored, so as to ensure the stable operation and good effect of the cooling system.
6. Safety: Low-temperature warehouses should consider safety, including fire protection systems, emergency exits, etc., to deal with emergencies such as fires and accidents.
7. Environmental protection: low-temperature warehouses should meet environmental protection requirements, including noise, wastewater, waste gas and other treatment measures.
It is important to note that different countries and regions may have different standards and regulations, and the specific requirements can be determined according to local laws and standards.
