一、冷冻板制冷的基本原理众所周知,冰在融化的过程中,要吸收大量的融解热,使周围介质的温度降低,而冰的温度恒定不变,所以具有很好的恒温特性,但因其冰点(0℃)较高,故只能制取0℃以上的温度。
First, the basic principle of refrigeration plate refrigeration As we all know, ice in the melting process, to absorb a large amount of melt heat, the temperature of the surrounding medium to reduce the temperature of the ice constant, so it has good thermostatic properties, but because of its Freezing point (0 ℃) higher, it can only take more than 0 ℃ temperature.
