With the advances in modern science and technology, the development of refrigeration technology is rapidly progress, food cold chain refers to perishable food reproduction, storage, transportation, sale and consumption of all aspects will always be in front of the low-temperature environment regulations. Frozen technology as the basis, as a means of refrigeration technology, logistics phenomena at low temperatures. So cold storage building requirements of the various problems of production, transportation, sales, and other economic and technical considerations involved together, coordinating relations between each other to ensure that the processing, transportation and marketing of perishable foods. Food cold chain is processed by freezing, frozen storage, four refrigerated transport and refrigeration sales mix.

Experts, fresh fruits and vegetables generally use the lowest temperature of -2 ℃ high temperature library, aquatic, carnivorous fresh use at temperatures below -18 ℃ low temperature library. Large cold storage installation generally use ammonia as a refrigerant in centralized refrigeration systems, cooling equipment, mostly pipes, system complexity, automated control difficult. Some small refrigerator low temperature generally used as the refrigerant Freon distributed or centralized refrigeration system. In regard to the construction activity cold ones, cold storage prospects still very substantial. Low temperature, high temperature, cold storage temperature refrigeration company specializing Which?
