Control of Refrigerant Emissions
A number of systems are available that monitor the accidental release of refrigerants from air conditioning plant. These include:
-
refrigerant detectors – including infra-red, semi-conductor and electro-chemical detectors that link to a central alarm unit
-
indicator dyes – fluorescent or coloured dyes added to the refrigerant to show leakage sites
-
halide torch detectors – only appropriate for chlorine based substances such as CFCs or HCFCs
All of these systems work better when an air conditioning plant is contained in, for example a basement rather than exposed on a roof.
