REFRIGERATING FLUID WITH A LOW GLOBAL WARMING POTENTIAL FOR AUTOMOTIVE AIR CONDITIONING SYSTEMS IN SUMMER

ABSTRACT
Refrigerants with low global warming potential (GWP) are much needed in automotive air conditioning systems. This paper compares two refrigerants, R134a (GWP=1300) and R513A (GWP = 573) experimentally. The results show that the latter has lower cooling capacity, lower COP and lower discharge temperature than the former, revealing that R513A is a promising replacement of its high GWP partner.
