制冷系统：

A:压缩机（关键配件），一般情况下，小型冷库选用全封闭压缩机。中型冷库一般选用半封压缩。大型冷库选用半封压缩机。在选用时也可考虑选用氨制冷压缩机，因为氨制冷压缩功率大。并可一机多用，但安装及管理麻烦。

B：蒸发器：一般情况下高温库选用风机为蒸发器，其特点是降温速度快，但易造成冷藏品的水分损耗；中低温冷库选用无缝钢管制作的蒸发器为主，其特点是恒温效果好，并能适时蓄冷。

C：冷凝器：冷凝器有空气冷却、水冷却和空气与水结合的冷却方式。空气冷却只限于在小型冷库设备中应用，水冷却的冷凝器则可用于所有形式的制冷系统。

Freezing means lowering the temperature and allowing the object to solidify and freeze. Also called "refrigeration", it is the application of thermodynamics principle, the method of artificially manufacturing low temperature, refrigerator and air conditioner are all based on the principle of refrigeration. From the chemical point of view, it is generally used a gas with a high critical point, pressurized and liquefied, and then it is vaporized and absorbed, and this process is repeated. When liquefying, it is exothermic in other places, and when it is vaporized, it absorbs heat to the required range. .
