摘要(Abstract):

本文从变质量热力学的基本原理出发,建立了包括背压腔与压缩腔在内的带自调背压机构的涡旋压缩机工作过程的热力学模型;通过求解压缩机热力学模型和进行动力计算,分析了背压孔的一般运动规律。该方法以确保压缩机具有较高的容积及机械效率为限制条件。
On the principle of changeable mass thermodynamics, a thermodynamic model of working process for scroll compressor with self-adjusting back-pressure mechanism is established in this paper. General motion low of back-pressure ports position is developed by solving thermodynamic model of compressor and carrying out dynamical computation. In this method, the guaranty of higher volumetric and mechanical efficiency is regarded as the confined condition.
