冷库设计：
*步冷库设计主要通过对冷库的构造、材料、设备，以及当地的气候和对工程的要求进行的。根据设计要求包括工程概况和气候情况首先对冷库进行选址。
第二步设计冷库的隔热防潮结构并根据冷库要求进行材料结构的选择。然后根据提供的材料的传热层系数及冷库设计要求进行冷负荷计算并汇总，然后根据负荷计算得出*佳的冷库系统设计方案。接下来对压缩机和辅助设备进行选型计算包括压缩机的参数和台数，辅助设备有冷凝器、中间冷却器、油分离器、高压储液器、冷风机等。下一步是对冷库系统管道的设计，有系统管道和阀门的设计要求，管道流速要求及蒸发器供液管的设计等。
Cold storage is *inly used for frozen processing and refrigeration of food. It keeps the indoor temperature low through *nual refrigeration. The cold storage design building is different from the general industrial and civilian buildings and has its unique structure. The walls, floors, and flat roofs of the cold storage are covered with a certain thickness of ther*l insulation to reduce the heat from the outside world. In order to reduce the radiation energy that absorbs the sun, the su*ce of the outer wall is generally painted white or light color when designed.
Cold storage design:
The first step in the cold storage design is *inly through the construction of the cold storage, *terials, equipment, as well as the local cli*te and engineering requirements. According to the design requirements, including the engineering and cli*te conditions, the cold storage site is first selected.
The second step is to design the insulation and moisture protection structure of the cold storage and to select the *terial structure according to the requirements of the cold storage. Then according to the heat transfer layer coefficient of the *terials provided and the design requirements of the cold storage, the cooling load is calculated and sum*rized, and then the opti*l design scheme of the cold storage system is obtained based on the load calculation. Next, the type selection of compressors and auxiliary equipment includes the parameters and number of tables of compressors. The auxiliary equipment includes condensers, intermediate coolers, oil separators, high-pressure reservoirs, and cooling fans. The next step is the design of the cold storage system pipeline, the design requirements of the system pipeline and valves, the flow rate requirements of the pipeline and the design of the evaporator supply pipe.
