Environmental Sustainability of Automobile AIR-Conditioning System with Refrigerant R1234YF
International Journal of Advance Research and Innovation, 2015 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.
