Performance of Heat Pump Air Conditioning with R1234ze (HFO) as a Refrigerant
Journal of Optimization, Volume 2024, Issue 1, 2024.The study shows that refrigerants R1234ze (E) and R1234ze (Z), known for their low global warming potential, are likely to become primary choices in heat pump air conditioning for residential and commercial use. The research evaluates the thermodynamic properties of R1234ze (Z) using experimental, thermodynamic, and numerical analyses.

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.
