Résumé

With the advancing worldwide phase out of HCFCs, UNEP’s OzonAction Division of Technology has produced a series of factsheets on the safe use of the new alternatives. Although there are several refrigerants with a higher pressure than R22, most of these are within a pressure range which is not more than 50% greater. Carbon dioxide (R744) has a substantially higher pressure – typically by a factor of six. For some others such as R410A and R32, the pressure is notably higher than what people are used to with R22, so paying attention to the pressure aspects still remains important.
