醫(yī)藥冷庫設(shè)備廠家介紹制冷的幾點(diǎn)常識(shí)：
Medicine, cold storage equipment manufacturer to introduce some common sense of refrigeration:
1、過熱度：過熱蒸氣的溫度和其壓力對(duì)應(yīng)的飽和溫度之差；
1, the degree of superheat, superheated steam temperature and its corresponding saturation temperature difference stress;
2、過熱蒸氣：蒸氣的溫度高于其壓力所對(duì)應(yīng)的飽和溫度時(shí)此時(shí)的蒸氣稱為過熱蒸氣；
2, superheated steam, steam temperature is higher than the pressure of the saturated temperature steam called overheating steam at this time;
3、制冷劑R22的化學(xué)成分為二氟一氯甲烷（CHClF2）；醫(yī)藥冷庫
The chemical composition of 3, refrigerant R22 as methylene fluoride a chloride (CHClF2);
4、滿液式蒸發(fā)器：制冷劑液體在殼管式換熱器管外蒸發(fā)，從而冷卻管內(nèi)液體載冷劑稱為滿液式蒸發(fā)器；
4, full liquid type evaporator: refrigerant liquid evaporation in the shell and tube heat exchanger tube, thereby cooling tube cold liquid carrying agent called full liquid type evaporator;
5、過冷度：如果液體的溫度低于其壓力所對(duì)應(yīng)的飽和溫度時(shí)則此時(shí)液體稱為未飽和液體，或過冷液體，其溫度之差稱為過冷度。
5, super-cooling degree: if the temperature of the liquid is lower than the pressure of the saturated temperature when the liquid is called unsaturated, at this time or supercooled liquid, the temperature difference is called supercooling degree.
