Increasing recognition and acknowledgment of the environmental impact associated with the use of refrigeration and air conditioning equipment has brought about changes in the composition of refrigerant gases and in the way they are being used. This heightened awareness on the part of end users and consumers is playing an important role in accelerating these changes through corporate responsibility agendas, although the evolution of the industry is primarily being driven by legislation introduced to limit ozone depletion and global warming.
Refrigerant gases are used as a heat exchange material in equipment such as refrigerators, freezers and air conditioning systems. The refrigerant gas is pumped round a closed loop, being repeatedly evaporated, condensed and transferring heat away from where it is not required.
