Performance of an oil-free linear compressor using R1234yf
As an alternative to the hydrocarbons (HCs), R1234yf synthetic refrigerant from the family of the hydrofluoroolefins (HFOs), has emerged recently as a replacement fluid for R134a. The purpose of this study is to investigate the performance of an oil-free linear compressor using R1234yf operated at different pressure ratios for household refrigerators. A mathematical model for the oil-free linear compressor using R1234yf has been developed. The compressor stroke was set as 14 mm for minimum dead volume with the evaporator temperature of – 23 °C. The result shows that the bleed flow rate can be 5% of main flow rate, and the resonant frequency varies between 32.7 Hz and 35.3 Hz for pressure ratios of 5-12. Cylinder mean pressure, shaft power, bleed flow, and clearance seal power loss increase with the pressure ratio. At pressure ratio of 10, and clearance seal power loss represents 8% of shaft power.
