What are the economical and technical advantages of HFCs for society ?
Because HFCs offer similar technical and beneficial characteristics, particularly a low level of chemical reactivity they can usually replace CFCs in existing equipment, with only minimal modifications. Users of hydrocarbons and ammonia, on the other hand, have to take into account flammability and toxicity . Major modifications or even relocation, involving significant capital expenditure and appropriate training of reliable staff, may therefore be required before existing equipment can be used safely. International Governmental Conferences and Meetings around the world have acknowledged the products of the HFCs family as important replacements for CFCs and the HCFCs in their most important applications including refrigeration, air conditioning and insulation foam blowing agents. Even if some countries expressed their intention to phase them out on the sole basis of their intrinsic global warming potential, there is no national or international regulation in place yet. In brief, when
