现代山东冷库造价的结构正向装配式发展，制成包括防潮层和隔热层的库体构件，做到现场组装，其优点是施工方便、快速，且可移动，但造价比较高。

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.

冷库隔热材料的选用必须因地制宜，既要有良好的隔热性能，又要经济实用。隔热材料分几种类型，一种是加工成固定形状及规格的板块，有固定的长度、宽度和厚度，可根据冷库库体安装的需要选择相应规格的板块，高、中温冷库一般选用10cm厚的库板，低温冷库及冻结冷库一般选用12cm或15cm厚的板块另一种可以用聚氨脂喷涂发泡，把材料直接喷到已经建成的砖或混凝土仓库中，定形后既防潮又隔热。隔热材料板块有聚氨脂、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，隔热性较好，但成本较高;聚苯脂吸水性强，隔热性较差，但成本较低。

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.

冷库制冷系统的选择主要是压缩机与蒸发器的选用，制冷系统是冷库的核心，主要由压缩系统、冷凝系统、蒸发系统和调节阀四大部分组成，另外还有风扇、导管和仪表等辅件。整个制冷系统是一个密封的循环回路，制冷剂在该密封系统中循环，根据需要控制供应量和进入蒸发器的次数，以获得适宜的低温条件。

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.

蒸发器的作用是向冷库内提供冷量，蒸发器按装在冷库内，利用鼓风机将冷却的空气吹向库内的各个部位，大型冷库常用风道连接蒸发器，延长送风距离，使库温下降更加均匀。

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.
