在很早以前，中國古代人就知道在冬天的時候把冰塊存儲在山洞里，在夏天來臨的時候拿出來乘涼，這是最早的冷庫，也是大自然的饋贈，如今隨著經(jīng)濟發(fā)展，冷庫的演變也多種多樣，不再像以前是有錢人的專享，而是日漸走進了各個領域，成為人們生活的一部分。
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.
當前，冷庫設備的制冷方式有兩種，一種是直接制冷，一種是間接制冷，直接制冷的方式是通過制冷機的蒸發(fā)器設備在制冷裝置的箱體和建筑物內(nèi)，利用制冷劑的蒸發(fā)，直接冷卻空氣，依靠冷卻的空氣讓貨物也進行冷卻。這種方式有很大的優(yōu)點，就是冷卻的速度快，但是傳熱的溫差小，應用的范圍十分普遍。
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.
還有一種方式，就是制冷設備的間接冷卻，間接冷卻是依靠制冷設備中制冷劑的蒸發(fā)，從而讓承載制冷劑的物品冷卻，再用制冷劑輸入制冷設備中，通過換熱器冷卻其中的空氣。這種冷卻方式，速度比較慢，總體的溫差大，因此只用于很少的特殊場合。因此，在實際應用中，直接制冷是廣泛應用的。
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.
當前我國的制冷設備發(fā)展還不夠完善，很多有特殊功能或者高溫差制冷設備需要從國外進口，因此價格也比較昂貴。在這里，溫馨提示想安裝冷庫的朋友們，如果是小型的保鮮冷庫之類，完全可以放心的選擇國內(nèi)設備，如果是有特殊需求的高端大型冷庫，那么在進行冷庫建設的時候就需要選擇進口制冷設備了。
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.
