一般情況下，小型冷庫選用全封閉壓縮機為主。山東冷庫造價因全封閉壓縮機功率小，價格相對便宜;中型冷庫一般選用半封閉壓縮機為主;大型冷庫選用半封閉壓縮機，在選用時，也可考慮選用氨制冷壓縮機，因為氨制冷壓縮機功率大，并可一機多用，但安裝及管理比較煩瑣。

Under normal circumstances, the selection of small cold storage closed compressor. Because closed compressor power is small, the price is relatively cheap; cold storage is generally used in semi hermetic compressor; large refrigerator using semi hermetic compressor, in the selection, also consider the use of ammonia refrigeration compressor, because ammonia refrigeration compressor power, and the use of a machine, but the relatively cumbersome installation and management.

冷庫的大小要根據貯藏產品在冷庫內堆放所必需占據的體積，加上行間過道，堆與墻壁、天花板之間的空間以及包裝這間的空隙等計算出來。確定容量這后，再確定冷庫的長度與高度。

The size of the cold storage should be calculated according to the volume that the storage product must occupy in the cold storage, plus the aisle between the rows, the space between the wall and the ceiling, and the space between the packages. Determine the capacity, and then determine the length and height of cold storage.

冷庫制冷系統的選擇主要是壓縮機與蒸發器的選用，制冷系統是冷庫的核心，主要由壓縮系統、冷凝系統、蒸發系統和調節閥四大部份組成，另外還有風扇、導管和儀表等輔件。

Refrigeration system of choice is the choice of the main compressor and evaporator, cold storage refrigeration system is the core, mainly by the compression system, condensing system, evaporation system and regulating valve four most, in addition to the fan, catheter and instrument accessories.

冷庫隔熱材料的選用必須因地制宜，既要有良好的隔熱性能，又要經濟實用。隔熱材料分幾種類型，一種是加工成固定形狀及規格的板塊，有固定的長度、寬度和厚度，可根據冷庫庫體安裝的需要選擇相應規格的板塊，高、中溫冷庫一般選用10cm厚的庫板，低溫冷庫及凍結冷庫一般選用12cm或15cm厚的板塊;另一種可以用聚氨脂噴涂發泡，把材料直接噴到已經建成的磚或混凝土倉庫中，定形后既防潮又隔熱。

The selection of heat insulation materials for cold storage must be in accordance with local conditions, not only with good heat insulation performance, but also economical and practical. Insulation materials of several types, one is processed into a fixed shape and specifications of the plate length, width and thickness are fixed, select the appropriate specifications of the plate according to the need of Refrigeratory library body installation, high temperature, cold generally 10cm thick base plate, cold storage and freezing cold storage or general use 12cm 15cm thick plate; another can use spray polyurethane foam, the material is sprayed directly into the already built brick or concrete warehouse, setting both waterproof and heat insulation.

壓縮機是制冷系統的心臟，它推動制冷劑在系統中循環。冷凝器的作用是排除壓縮后的氣態制冷劑中的熱量，使其凝結成液態制冷劑

The compressor is the heart of the refrigeration system, which pushes the refrigerant through the system. The function of the condenser is to eliminate the heat in the compressed gaseous refrigerant and condense it into a liquid refrigerant

在冷庫蒸發器的選用時，高溫冷庫以選用冷風機為蒸發器，其特點是降溫速度快，但易造成冷藏品的水分損耗;中、低溫冷庫選用無縫鋼管制作的蒸發排管為主，其特點是恒溫效果好，并能適時蓄冷。

In the selection of cold storage evaporator, high temperature refrigerator to choose cooling fan for an evaporator, which is characterized by fast cooling, but it is likely to cause the loss of cold water collection; in cold storage, selection of seamless steel tube is made of evaporative emission control, which is characterized by constant temperature effect, and the timely storage.
