摘要

Since January 1,1996,the production of CFCs is forbidden in the developed countries,and for the HCFCs a phase- out schedule until 2030-in the EU until 2015–already exists.In some countries even more rigid phase-out schedules have been decided,the EU will phase out R-134a for automotive air conditioning,Denmark and Austria want to phase out HFCs due to their global warming potential.But what are the alternatives and what is their impact on the climate change? rnThe alternatives for the HCFCs,which are still in use,and the HFCs are the old refrigerants,substances like ammonia(R-717),the hydrocarbons(R-290,R-1270,R-600a),water(R-718)and CO_2(R-744).The selection criteria for refrigerants have to cover efficiency,safety,and environmental acceptability.Within these criteria the environment expressed by the TEWI,i.e.refrigerant losses during lifetime and CO_2 emissions caused by the production of drive energy and the drive energy,respectively,becomes a very important issue.In this context efficiency gets the highest priority,and efficiency,as can be demonstrated,is mainly the result of technology development and the correct integration of units into systems.
