Refrigerants and the Environment

CRT follows the issues of refrigerants closely through the IOR (Institute of Refrigeration), IIR (International Institute of Refrigeration), ACRIB (Air conditioning and Refrigeration Industry Board) and the UN Refrigeration Technical Options Commmittee (RTOC).

The Montreal protocol has been successful in enforcing the phase out of ozone layer damaging CFCs and also the phasing out of HCFC in new equipment and insulation material. Although the chlorine free HFC refrigerants are non-ozone layer depleting, many have a high GWP (Global Warming Potential).

In the latest version of the EU F gas directive refrigerants and there are now bans on substances with a GWP above 2500 and a reducing production cap for substances above GWP 150.

Refrigerants under development are unsaturated HFCs (HFOs) and natural refrigerants such as Carbon Dioxide.

Key Issues are:
