Résumé

Linear compressor is a promising alternative for commercial refrigerator using R290. In this paper, a design program of linear compressor is set up. The leakage mass flow rate is modeled based on small hole leakage principle. The errors of the model are within 10%. The cooling performance of linear compressor with different piston diameter for commercial referigerator using R290 is analyzed. As the linear compressor is set to have the same swept volume, small piston diameter is beneficial to the COP improvement, but has a few decrease of cooling capacity. As the linear compressor is set to have the same cooling capacity by adjusting power frequency, COP of the linear compressor with piston diameter of 28?mm and 30?mm gets a little decrease because the power frequency deviates from the inherent frequency. The optimal piston diameter of 12 CC swept volume for the commercial refrigeration is suggested to be from 30?mm to 32?mm.
