介绍制冷剂的5大相关性能：
Introduce the five related refrigerants performance:
1、导热系数、放热系数高，可提高热交换效率。医药冷库
1, high coefficient of thermal conductivity, heat release, can improve the efficiency of heat exchange.
2、便于采用一般的冷却水或空气进行冷凝，也就是制冷剂的临界温度要高。
2, easy to use the general cooling water or air to condense, the critical temperature of refrigerant is high.
3、蒸发压力和冷凝压力适中，也就是说在常温下，应具有较低的冷凝压力，而制冷剂蒸发压力最好接4、近大气压力。甚至高于大气压力，宜采用在大气压力下沸点较低的物质。
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、要求制冷剂的密度和粘度小，制冷剂密度小可减小输送管的管径，还会降低压缩机的功率消耗。
5, for refrigerant density and low viscosity and density of refrigerant xiaoke minimize delivery pipe diameter, may also reduce the compressor power consumption.
6、具有较稳定的化学性质，在任何温度下应不会分解或化合，对管道无腐蚀，对润滑油应不起化学反应，对润滑油的溶解性应适度。无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.
