Novel Reduced GWP Refrigerant Compositions for Stationary Air Conditioning
The working fluids most widely used for small and mid-sized air conditioning systems globally are R-410A and R22. While these fluids have many positive attributes for cooling and heating, they are the subject of valid criticisms regarding their high direct global warming potential (GWP) and, in the case of R-22, ozone depletion potential (ODP) also. In the interest of improved environmental sus...

متن کاملRefrigerant mass migration modeling and simulation for air conditioning systems
Refrigerant mass migration and redistribution are regarded as key factors affecting the cycling perfor mance of air conditioning and refrigeration systems. A dynamic model of an R134a automotive air conditioning system is presented as an example in this paper to capture the refrigerant migration during compressor shut-down and start-up operations. Model validation against experimental data dem...
متن کاملSustainability of Automobile Air- Conditioning System Using Refrigerant R1234yf Instead of R134a
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 refrigerant with GWP value less than 150. R1234yf is a new refrigerant which has lower GWP value of 4. Effect of blower speed has been compared and flammability issue of R1234yf has been addre...
