在很早以前，中国古代人就知道在冬天的时候把冰块存储在山洞里，在夏天来临的时候拿出来乘凉，这是最早的冷库，也是大自然的馈赠，如今随着经济发展，冷库的演变也多种多样，不再像以前是有钱人的专享，而是日渐走进了各个领域，成为人们生活的一部分。
In a long time ago, Chinese ancient people knew in the winter the ice storage in the cave, comes out and cool in summer, this is the first cold storage, also is the gift of nature, is now with the economic development, the evolution of the cold storage is also varied, are no longer the exclusive of the wealthy, but increasingly went into the various fields, become part of people's life.
当前，冷库设备的制冷方式有两种，一种是直接制冷，一种是间接制冷，直接制冷的方式是通过制冷机的蒸发器设备在制冷装置的箱体和建筑物内，利用制冷剂的蒸发，直接冷却空气，依靠冷却的空气让货物也进行冷却。这种方式有很大的优点，就是冷却的速度快，但是传热的温差小，应用的范围十分普遍。
At present, there are two main ways of refrigeration and cold storage equipment, one is direct cooling, is a kind of indirect cooling, direct cooling by refrigerating machine in the refrigerating chamber evaporator equipment and buildings, using evaporation of refrigerant, cooling air directly, depending on the cooling air make goods for cooling. This way has a lot of advantages, is the cooling speed, but the heat transfer temperature difference is small, the scope of application is widespread.
还有一种方式，就是制冷设备的间接冷却，间接冷却是依靠制冷设备中制冷剂的蒸发，从而让承载制冷剂的物品冷却，再用制冷剂输入制冷设备中，通过换热器冷却其中的空气。这种冷却方式，速度比较慢，总体的温差大，因此只用于很少的特殊场合。因此，在实际应用中，直接制冷是广泛应用的。
There is a way, that is, the indirect cooling refrigeration equipment, indirect cooling is depend on the evaporation of refrigerant in refrigeration equipment, so that the bearing items refrigerant cooling, reoccupy input refrigerants in refrigeration equipment, through the heat exchanger to cool the air. This type of cooling speed is slow, the overall temperature difference is big, so only for a few special occasions. Therefore, in practice, direct cooling is widely applied.
当前我国的制冷设备发展还不够完善，很多有特殊功能或者高温差制冷设备需要从国外进口，因此价格也比较昂贵。在这里，温馨提示想安装冷库的朋友们，如果是小型的保鲜冷库之类，完全可以放心的选择国内设备，如果是有特殊需求的高端大型冷库，那么在进行冷库建设的时候就需要选择进口制冷设备了。
Refrigeration equipment development of the current our country is not perfect enough, there are many special functions or poor high temperature refrigeration equipment need to be imported from abroad, so the price is more expensive. Here, the warm prompt to install the refrigerator the friends, fresh cold storage, if it is small, can be at ease completely the choice of domestic equipment, if there are special requirements for high-end large cold storage, so in the construction of cold storage time will need to choose imported refrigeration equipment.
