决定保鲜冷库质量因素有哪些
2016-12-29 11:16:56
对于很多的冷库安装厂家来说,在使用冷库的时候,会碰到很多的问题。由于要根据不同的冷冻产品决定冷库的温度,因此很多的时候会有一些耗能。那么,决定冷库安装质量的因素有哪些呢?
For many cold storage installation manufacturers, in the use of cold storage, will encounter a lot of problems. According to the different frozen products to determine the temperature of the refrigerator, so a lot of time there will be some energy consumption. So, what are the factors that determine the quality of cold storage installation?
1、隔热材料的选择与设计对冷库质量十分重要
1, the selection and design of thermal insulation material is very important to the quality of cold storage
冷库保温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10厘米厚的库板,低温冷库及冻结冷库一般选用12厘米或15厘米厚的板块;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。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。一般,冷库安装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。
Cold storage insulation materials must be selected according to local conditions, not only have a good thermal 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 storage is generally 10 cm thick base plate, cold storage and freezing cold generally used 12 cm or 15 cm 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. Insulation plate with polyurethane, polystyrene grease etc. Polyurethane water absorption and heat insulation is good, but the cost is higher; Ekonol strong water absorption, heat insulation performance is poor, but the cost is low. In general, the structure of the cold storage installation is in front of the assembly type development, made of damp proof layer and thermal insulation layer of the library components, so that on-site assembly, the advantage of the construction is convenient, fast, and mobile, but the cost is relatively high.
2.“从20到200毫米之间的聚氨酯板材都能生产,每次可同时生产1—5件。”
2 "from 20 to 200 mm polyurethane board can be produced, each time can be produced at the same time 1 - 5 pieces."
3、冷藏库容量及温度的确定
3, cold storage capacity and temperature determination
要满足储藏和出货对温度不同要求的各种产品,冷库的大小要根据常年要贮藏产品的最高量来设计。这个容量是根据贮藏产品在冷库内堆放所必需占据的体积,加上行间过道,堆与墙壁、天花板之间的空间以及包装这间的空隙等计算出来。确定容量这后,再确定冷库的长度与高度。一般冷库安装设计时还要考虑必要的附属建筑 和设施,如工作间、包装整理间、工具库和装卸台等,这样冷库质量才能得到保证。
To meet the requirements of storage and shipment of different temperature requirements of the product, the size of the cold storage according to the maximum amount of storage products to be designed. This capacity is required according to the storage products piled up the volume occupied in the refrigerator, and row aisle, stack and the space between the walls, the ceiling and the gap between the calculated packing etc. Determine the capacity, then determine the length and height of the cold storage. General cold storage installation design must also consider the necessary ancillary buildings and facilities, such as the work room, packing room, tool library and loading and unloading platform, so cold storage quality can be guaranteed.
