Cold storage is ina specific temperature and relative humidity conditions, processing and storage of special buildings food, feed liquid material, biological products, medicine and other supplies. While the food cold storage isa part of food processing factory, its geographical location ponents directly affect health and food needs of the local people's life. Should design that the cold storage is pragmatic by meteorological phenomena , geographical feature and reality to Pingdingshan area waiting for condition, go along such as load , refrigeration machine room and chilled water system designs that to cold storage flat surface , equipment and machinery hedging structure , cooling down secretly scheming against. The cold storage designs that the primo collects actual data such as meteorological phenomena , geographical feature designing area , the queen is allotted a headquarter in proper order to nominal volume , altitude , cold room contained by cold storage flat surface; Heat-barrier material in hedging structure chooses row of cloth , refrigerates the door, equipment load , machinery load , cold room air cooling down assign system and the aeration being ventilated; Refrigeration equipment chooses c
