REFRIGERATION SYSTEMS AND HEAT PUMPS, OPTIMAL IN TERMS OF ENERGY AND FOR ENVIRONMENT PROTECTION, WITH NATURAL HEAT CARRIERS

Abstract

Global warming is a huge challenge for the future, for all countries, so the global warming potential of refrigerants is a major issue. Natural refrigerants are already an efficient, cost-effective and safe solution in many applications in refrigeration and air conditioning, including in developing countries and warm countries, even if solutions must be adapted. They often require different equipment than « chemical » refrigerants (CFCs, HCFCs, HFCs) for technical and safety reasons. They should be better promoted for new equipment and the replacement of old equipment. They still require improvements, research and development in various applications and we are working on these improvements. Natural Refrigerants are a cost efficient alternative.
