Fixed Refrigerant Detection Systems for HFCs, HFC/HFO blends, HFOs and HCFCs (GN20)
This Guidance Note is aimed at those involved in the specification, design and installation and operation of multi point fixed refrigerant detection systems to monitor hydro-fluorocarbon (HFC), hydrofluoroolefin (HFO), HFC/HFO blends and hydro-chloro-fluorocarbon (HCFC).
Many of the principles and associated benefits of fixed leak detection systems also relate to hydrocarbon (HC) and Carbon Dioxide (CO2) refrigerants and will be considered in separate documents.
The areas covered in this Guidance Note are:
