Parameters Optimization of Linear Compressor for Refrigerator

Abstract:

Recently linear compressor with a free piston is widely paid attention to for its high efficiency. This paper presents parameters optimization of linear compressor used for Refrigerator. The system equations of linear compressor are established through system analysis and solved by variable step Newmark method. The piston movement, current, input power, effective work, resistive loss, damping loss and efficiency are calculated for the optimization from the system equations. Coil wire diameter, stroke and cylinder diameter are important parameters of linear compressor, which have great importance on its performance. The coil wire diameter was changed to find out its affect to loss of resistance. The efficiency of linear compressor and current of the coil are analyzed with the same exhaust volume and different stroke and cylinder diameter. Through the analysis the parameters of the linear compressor are optimized.
