A one story steel structure cold storage with an area of approximately 20000 square meters, a nominal volume of 158100 cubic meters, a total storage capacity of 30020 tons, and a net height of 9.3 meters. It is divided into 9 cold rooms, some of which are dual-use for high and low temperatures. The low-temperature storage and variable temperature storage adopt a carbon dioxide (R744) and Freon (R507) cascade refrigeration system. The variable temperature storage (high temperature) adopts a CO2 cooling system, and the hall adopts a Freon (R507) refrigeration system. The end device is a ceiling mounted air cooler, the low-temperature and variable temperature storage systems use automatic water defrosting, and the hallway system uses air defrosting.
