The refrigerant should have the following properties: The refrigerant should have good thermal, physical, chemical, environmental and other performances. Because the completely ideal refrigerant does not exist, people should try to choose a refrigerant with better performance.
1. The refrigeration capacity per unit volume should be large. The larger the refrigeration capacity, the smaller the circulation amount of the refrigerant when a certain amount of refrigeration is required, which can reduce the volume of the refrigeration equipment.
2. Evaporation pressure and condensing pressure are moderate, that is, at normal temperature, there should be a lower condensing pressure, and the refrigerant evaporation pressure is preferably close to atmospheric pressure. Even above atmospheric pressure, it is preferable to use a substance with a lower boiling point at atmospheric pressure. Small cold storage price
3. It is convenient to use ordinary cooling water or air for condensation, that is, the critical temperature of the refrigerant is high.
4. The solidification temperature is low under normal pressure.
5. The density and viscosity of the refrigerant are required to be small, and the low density of the refrigerant can reduce the diameter of the conveying pipe and reduce the power consumption of the compressor.
6. High thermal conductivity and high heat release coefficient can improve heat exchange efficiency.
7. It has relatively stable chemical properties. It should not decompose or combine at any temperature. It has no corrosion to the pipeline. It should not react chemically to the lubricating oil. The solubility of the lubricating oil should be moderate. Unlimited dissolution reduces cooling capacity. Built cold storage price
8, should be non-toxic, non-irritating, not easy to burn and explode.
