UK: The Institute of Refrigeration (IoR) has published a new guidance note outlining all the criteria that should be adopted in selecting the most appropriate refrigerant for the application.
IoR Guidance Note 37 Refrigerant Selection is targeted at equipment owners, operators and advisors making purchasing decisions that will influence the selection of refrigerant and equipment.
In a separate IOR statement on choice of refrigerant, the IoR recommends that systems and equipment should only be installed using refrigerants with a GWP over 300 where a low GWP option with equal or better efficiency is not available. Ideally, the IoR recommends a refrigerant with a GWP of 10 or less but accepts that this may not always be practical.
For current equipment using a refrigerant with a GWP greater than 300, the IoR advises putting in place a plan to replace the system at end of life with a lower GWP refrigerant where possible.
The guidance note gives a more complete explanation of all the criteria that should be adopted in selecting the most appropriate refrigerant for the application.
