...K. Mani; S. Krishnan A thermodynamic study was performed on a vapor compression refrigeration system (VCRS) with domestic liquefied petroleum gas (LPG) as a refrigerant. LPG's coefficient of performance, power consumption, and refrigeration capacity are compared with R134a. There were three...

... of the energy, exergy, and environmental-related aspects of low-GWP hydrofluoroolefin refrigerants—R1234yf, R1234ze(E), and R1336mzz(Z)—as substitutes for the high-GWP R134a, which is used in a 200-liter household refrigerator having a 157 W cooling power. Pressure ratio, volumetric refrigeration capacity...

... in developing nations to accomplish a condition of 85% decrease in the use of HFCs. The refrigerant R134a used in mobile air conditioning has a global warming potential (GWP100) of 1300, which prompted researchers to look for new low GWP refrigerants. Recent research has revealed that the HydroFluoroOlefin (HFO...

...S. S. Harish Kruthiventi; G. Venkatarathnam Capillary tube expansion devices are used extensively in small refrigeration and unitary air conditioning systems. R1234yf is likely to replace R134a in the next few years in many small refrigeration systems worldwide because of the new environmental...
