英文摘要	Based on the first law of thermodynamics, the law of conservation of mass and the gas state equation, the thermodynamic modeling of the oil-free scroll compressors was constructed by considering the internal leakage of the working chambers and the heat transfers between the wrap of the working chamber and the gas. The variety of volume, temperature, pressure and mass of gas in the whole processes of suction-compression-discharge was obtained using Euler method to solve the established thermodynamic model. The variation law under different heat transfer and leakage conditions was compared and discussed. The performance test of an oil-free scroll compressor under different crankshaft speeds was carried out. The temperature, displacement, power were tested for different discharge pressures respectively. The results show that heat transfer has the greatest influence on pressure and temperature, and the leakage has the greatest influence on the working chamber mass. With the increasing of speed, temperature, displacement, power a clear upward trend is shown. The developed thermodynamic model provides some guidance and reference for the researches and performance analyses of oil-free scroll compressors. © 2018, China Mechanical Engineering Magazine Office.
