現代山東冷庫造價的結構正向裝配式發展，制成包括防潮層和隔熱層的庫體構件，做到現場組裝，其優點是施工方便、快速，且可移動，但造價比較高。

The structure of modern cold storage is developed in a positive assembly way, and it is made into a warehouse structure including damp proof layer and heat insulation layer. It has the advantages of convenient construction, quick speed, and moving, but the cost is relatively high.

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。隔熱材料板塊有聚氨脂、聚苯脂等。

The selection of thermal insulation materials for cold storage must be in accordance with local conditions. It not only has good heat insulation performance, but also is 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 can use another spray polyurethane foam, the material is sprayed directly into the already built brick or concrete warehouse, setting both waterproof and heat insulation. The heat insulation material has polyurethane, polyphenyl grease and so on.

聚氨脂不吸水，隔熱性較好，但成本較高;聚苯脂吸水性強，隔熱性較差，但成本較低。

Polyurethane has no water absorption, good heat insulation, but higher cost; polyphenyl fat water absorption is strong, heat insulation is poor, but the cost is low.

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分組成，另外還有風扇、導管和儀表等輔件。整個制冷系統是一個密封的循環回路，制冷劑在該密封系統中循環，根據需要控制供應量和進入蒸發器的次數，以獲得適宜的低溫條件。

The 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 control valve of four parts, in addition to the fan, duct and instrument accessories. The whole refrigeration system is a sealed circulation circuit, the refrigerant is circulating in the sealing system, and the quantity of the supply and the number of the evaporator entering the evaporator are controlled according to the requirement, so as to obtain the suitable low temperature condition.

蒸發器的作用是向冷庫內提供冷量，蒸發器按裝在冷庫內，利用鼓風機將冷卻的空氣吹向庫內的各個部位，大型冷庫常用風道連接蒸發器，延長送風距離，使庫溫下降更加均勻。

The role is to provide cooling evaporator to refrigerator evaporator is installed in the refrigerator, the air will cool air blows all parts in the library, a large cold common duct connected with the evaporator, prolong the air distance, the temperature drop is more uniform.
