When selecting refrigerants, the following issues should be noted:
Low freezing temperature, must be below the operating temperature of the refrigeration system.
② High thermal conductivity coefficient, meaning both thermal conductivity and heat capacity should be high, while viscosity should be low.
③ Stable in nature, with low corrosiveness.
④ Non-toxic and safe, with affordable pricing.
⑤ Affordable and easily accessible.
The advantages of using refrigerant include:
The refrigeration system can be condensed into a smaller area, facilitating the manufacturing, installation, and operation management of the entire unit, thereby enhancing refrigeration efficiency. Additionally, it transfers chilled energy over longer distances. Moreover, it will reduce the amount of refrigerant required and minimize the risk of refrigerant leaks.
2. Easy for distribution and control of cooling capacity, particularly for large capacity air-cooled units in centralized cooling systems.
The refrigerant used has a high heat capacity, making it easier to stabilize the temperature of the cooled object.
