What are the most common refrigerants used in IQF evaporator coils?


The choice of refrigerant for an IQF evaporator coil will depend on several factors, including the operating temperature, the efficiency of the refrigeration system, and the environmental impact of the refrigerant. Some common refrigerants used in IQF evaporator coils include:


Ammonia (NH3): Ammonia is a common refrigerant used in industrial refrigeration systems, including IQF evaporator coils. It has excellent thermodynamic properties, is energy-efficient, and is not harmful to the ozone layer. However, it is toxic and can be a safety concern if not handled properly.


R-22: R-22 is a hydrochlorofluorocarbon (HCFC) refrigerant that was commonly used in refrigeration systems, but it is being phased out due to its impact on the ozone layer. It has good thermodynamic properties and is still in use in some older refrigeration systems.


R-404A: R-404A is a hydrofluorocarbon (HFC) refrigerant that is commonly used in refrigeration systems, including IQF evaporator coils. It has good thermodynamic properties and is energy-efficient, but it has a high global warming potential and is being phased out in some regions.


R-507A: R-507A is a blend of HFC refrigerants that is commonly used in refrigeration systems, including IQF evaporator coils. It has good thermodynamic properties and is energy-efficient, but it also has a high global warming potential and is being phased out in some regions.


R-717 (ammonia): R-717, or pure ammonia, is an alternative to ammonia-based refrigerants. It has excellent thermodynamic properties and is non-toxic, but it requires special handling and safety precautions due to its high toxicity.


The choice of refrigerant will depend on the specific requirements of the application, including the operating temperature, efficiency, and environmental impact. It is important to select a refrigerant that is suitable for the specific application and to ensure that the refrigeration system is designed and operated safely and efficiently.
