1.前言由于石油危机,节省能源和节省资源正在成为产业界最为关心的事情,空调机也正在大力推行省电化和小形轻量化。根据1981年6月颁布的《合理使用能源法》(通称节能法),对空调机的耗能效率特别制定了准则。如图1所示,耗能效率正在逐年提高。本公司一直以提高压缩机、热交换器的效率、以及改善循环和控制来适应这种情况。由于压缩机的耗电在空调机中占据重要比例,因此,提高压缩机的效率一直是本公司最重要的研究课题。
1. Introduction As the oil crisis, saving energy and saving resources are becoming the industry’s most concerned thing, air conditioners are also vigorously promote the power saving and small lightweight. According to the Law on the Rational Use of Energy (commonly known as the Energy Conservation Law) promulgated in June 1981, guidelines have been specifically developed for the energy efficiency of air conditioners. As shown in Figure 1, energy efficiency is increasing year by year. The company has been to improve the compressor, heat exchanger efficiency, as well as improve the cycle and control to adapt to this situation. As compressor power consumption accounts for a significant proportion of air conditioners, improving compressor efficiency has always been the most important research topic for the Company.
