Which one is more expensive, a controlled atmosphere cold storage or an ordinary cold storage

　　Controlled atmosphere cold storage and ordinary cold storage are two common types of cold storage, which have significant differences in function, technical requirements and cost. Controlled atmosphere cold storage mainly adjusts the ratio of gases such as oxygen, carbon dioxide and nitrogen in the storage to inhibit the respiration of fruits and vegetables and extend the shelf life. It is suitable for long-term storage of high-value fruits, vegetables, flowers and other products. Ordinary cold storage mainly delays food corruption through low temperature environment, and is suitable for conventional refrigeration needs such as meat, seafood, and dairy products.

　　Controlled atmosphere cold storage usually uses highly airtight polyurethane insulation boards with a thickness of generally more than 100mm to ensure the gas regulation effect. In addition to conventional refrigeration units, it is also necessary to equip with gas conditioning equipment, and the equipment cost is relatively high. The construction requirements of controlled atmosphere cold storage are high, and the air tightness of the storage body and the accuracy of equipment installation must be ensured, and the installation cost is high. In addition, the gas conditioning equipment needs to be maintained regularly, and the operating cost is relatively high.

　　The material of ordinary cold storage is relatively simple, and the thickness of the insulation board can be selected according to the needs, generally 100mm or 120mm. Only the refrigeration unit needs to be configured, and the equipment cost is relatively low. The construction of ordinary cold storage is relatively simple, the installation cost is low, and the maintenance cost is relatively low, mainly focusing on the maintenance of refrigeration equipment.

　　The cost of controlled atmosphere preservation cold storage is significantly higher than that of ordinary cold storage, mainly due to its technical complexity and high equipment cost. When choosing the type of cold storage, enterprises should weigh it according to actual needs and budget. If high-value fruits, vegetables or flowers need to be stored for a long time, controlled atmosphere preservation cold storage is a better choice. If only conventional refrigeration function is required, ordinary cold storage is more cost-effective.
