Air- conditioning refrigerant R134a has value of global warming potential (GWP) 1300, which is much higher than MAC Directive (GWP below 150) passed in July 2006. This prompted a search for alternative eco-friendly refrigerant with GWP value less than 150. R1234yf is a new refrigerant which has lower GWP value of 4. Effect of blower speed in car air-conditioning has been compared and flammability issue of R1234yf has been addressed. Cooling time and relative humidity of car air-conditioning system using refrigerant R134a and R1234yf has also been discussed. The paper discusses various aspects for the replacement and provides a long term substitute of presently used refrigerant R134a in automobile air-conditioning for sustainable environment.
