Abstract:

According to the cooling demand of commercial refrigerator, an R290 linear compressor is developed and the experimental investigation on its cooling performance is carried out. The experimental results show that cooling capacity and COP of the linear compressor are 604 W and 1.42 on the rating conditions. Its COP decreases with the decreasing of cooling capacity and the COP is just about 1.02 with 40% cooling capacity. As the power frequency is lower than the nature frequency of linear compressor, cooling capacity and COP decreases greatly. The analysis on power consumption indicates that it is necessary to enhance the linear motor performance and reduce the gap between the piston and cylinder to improve the efficiency of linear compressor.
