Fruits and vegetables are generally kept fresh in a high-temperature warehouse with a minimum temperature of -2℃, some fruit display cabinets, vegetable display cabinets, and fresh-keeping cabinets on the market are used; aquatic products and meat products are kept fresh in a low-temperature warehouse with a temperature below -18℃. Such as fresh meat cabinet. Supermarket walk-in cooler. The low-temperature cold storage is mostly high-temperature storage.

　　A large-scale cold storage generally uses a centralized refrigeration system using ammonia as the refrigerant, and the cooling equipment is mostly piping, the system is complex, and it is difficult to realize automatic control. Some small cold storages at low temperatures generally use decentralized or centralized refrigeration systems with Freon as the refrigerant. In terms of construction, there are more civil cold storage, and the level of automation control is generally low.

　　 In recent years, my country’s cold storage construction has developed rapidly, mainly in the main fruit and vegetable production areas and vegetable bases in the suburbs of large and medium cities, such as Shanghai, Jiangsu and Zhejiang, Hubei, Henan and other places, and the demand for cold storage in important transportation ports Also relatively large. The development of agricultural industrialization has accelerated the rapid development of deep processing of agricultural products, fine processing of food, and freezing and cold storage. At the same time, requirements for cold storage tonnage, scale and form are getting higher and higher. With the advancement of science and technology and the development of the refrigeration industry, a new cold storage model is adopted in food production, processing and storage. It replaces the original construction mode and operation mode of cold storage buildings with brand-new architectural concepts such as standardization, modularization, and factoryization.

　　 In addition, in the past year, one of the most popular keywords is nothing more than   energy efficiency  . With the rapid development of the cold storage industry, the cold storage industry has taken advantage of the trend to continuously strengthen its own technological research and development capabilities and stop at the development of energy-efficient products. And production. For the cold storage industry, it is necessary to increase investment in ultra-low temperature cold storage, increase and improve the industry chain of ultra-low temperature cold storage as soon as possible, master and improve related technologies, and take the lead in launching influential products and brands. Energy-efficient technology products have become the dominant direction of future development, so innovative energy-saving technologies have become the constant development theme of the cold storage industry.
