介紹制冷劑的5大相關(guān)性能：
Introduce the five related refrigerants performance:
1、導(dǎo)熱系數(shù)、放熱系數(shù)高，可提高熱交換效率。醫(yī)藥冷庫
1, high coefficient of thermal conductivity, heat release, can improve the efficiency of heat exchange.
2、便于采用一般的冷卻水或空氣進行冷凝，也就是制冷劑的臨界溫度要高。
2, easy to use the general cooling water or air to condense, the critical temperature of refrigerant is high.
3、蒸發(fā)壓力和冷凝壓力適中，也就是說在常溫下，應(yīng)具有較低的冷凝壓力，而制冷劑蒸發(fā)壓力最好接4、近大氣壓力。甚至高于大氣壓力，宜采用在大氣壓力下沸點較低的物質(zhì)。
3, evaporating pressure and condensing pressure is moderate, that is to say, at room temperature should be lower condensing pressure, and refrigerants evaporating pressure had better pick up 4, close to the atmospheric pressure. Even higher than the atmospheric pressure, appropriate USES boiling point lower material under the atmospheric pressure.
5、要求制冷劑的密度和粘度小，制冷劑密度小可減小輸送管的管徑，還會降低壓縮機的功率消耗。
5, for refrigerant density and low viscosity and density of refrigerant xiaoke minimize delivery pipe diameter, may also reduce the compressor power consumption.
6、具有較穩(wěn)定的化學(xué)性質(zhì)，在任何溫度下應(yīng)不會分解或化合，對管道無腐蝕，對潤滑油應(yīng)不起化學(xué)反應(yīng)，對潤滑油的溶解性應(yīng)適度。無限的溶解可降低制冷量。

6, has a stable chemical properties, at any temperature should not break down, or combined, no corrosion to the pipeline, the oil should be no chemical reaction, the solubility of lubricating oil should be moderate. Can reduce the dissolution of infinite refrigerating capacity.
