Construction characteristics and cost of cold storage for fruits and vegetables

　　The temperature of fruit and vegetable fresh-keeping warehouse is usually set at 0℃~5℃, which is mainly used to inhibit the respiration of fruits and vegetables and prolong the fresh-keeping period. The core of this kind of cold storage construction lies in the stability and uniformity of temperature in the warehouse and proper humidity control. The cost is relatively moderate, but if it is necessary to increase the controlled atmosphere function (by adjusting the gas composition in the warehouse to keep fresh further), the cost will be significantly increased, because it is necessary to increase the controlled atmosphere equipment and more advanced airtight structure.

　　Configuration and cost analysis of low temperature freezer

　　Low-temperature freezer (commonly known as “freezer”) usually requires a temperature below -18℃, which is used to store ice cream, aquatic products, meat and other goods that need deep freezing. The key to the construction of this kind of cold storage lies in strong refrigeration capacity, thicker insulation board (such as 150mm or 200mm polyurethane sandwich board) and heating system to prevent the floor from frost heaving. These high-standard configurations make its unit cost generally higher than that of ordinary fresh-keeping warehouses, especially the cost of high-power compressors and low-temperature special evaporators is relatively high.

　　Cost of special function cold storage (such as medicine cold storage)

　　Medical cold storage has extremely strict standards for temperature accuracy, stability and monitoring system, which usually need to meet GSP specifications. The construction of this kind of cold storage not only needs high-performance refrigeration equipment, but also must be equipped with uninterrupted power supply, double circuits or standby units, automatic alarm and full temperature and humidity monitoring and recording system. In addition, there are higher requirements for the environmental protection and fire protection grade of the board. Therefore, its cost is relatively high in all kinds of functional cold storage, which is mainly reflected in the high reliability of equipment, redundant backup of the system and complex control system.

　　To sum up, the key to affect the construction cost of cold storage lies in the technical differences brought about by its functional positioning. From ordinary preservation to deep freezing, and then to medical storage with strict specifications, the more special the function and the higher the requirements, the overall cost will also rise. It is suggested that enterprises should communicate with professional refrigeration companies for specific needs before starting the project, so as to obtain a practical and cost-effective cold storage construction scheme.
