Résumé
Linear compressors are attractive for domestic refrigerator owing to high efficiency, free piston and possible oil-free operation. Minimizing the clearance volume is an approach to increase the volumetric efficiency thus cooling capacity. This is particularly beneficial for refrigerants that require high displacement due to high
friction. This paper experimentally compares the refrigeration performance of a linear compressor using R1234yf among using various clearance volumes and using an offset of 0 mm. Measurements with different clearances and an offset of 0 mm were carried out for compressor strokes of 11-13 mm and pressure ratios of 2.5-4.0 using R1234yf. The overall coefficient of performance (CoP) increases particularly for high pressure ratio.
