| 摘 要： | 压缩机的效率是衡量其完善性的重要指标,压缩机的等熵功是计算效率的一个基本参数,因此需要给出精确计算值。本文根据等熵过程始态、终态熵相等的原则,提出了一个计算往复活塞压缩机等熵过程理论循环功的精确计算方法,应用该方法可以提高压缩机效率的计算精度。该方法还可以方便地编制计算机程序。通过实例,对文中提出的精确计算方法和常用的压缩机等熵功计算方法的计算结果进行了比较,并对两者的差别进行了分析。

| Abstract: | The effciency is the representative of compressor performance; isentropic work is a parameter used to calculate compressor efficiency,and it is necessary to be calculated precisely. Based on the principle that entropy do not change in isentropic process,this paper presents a precise method to calculate isentropic process periodic work of compressors ,and advances the calculation precision of compressor efficiency. The precise method is easy to be adopted to computer code. An example is given in this paper to compare and analyse the calculation results of two methods. |
