“带经济器螺杆制冷压缩机的过程分析及系统设计计算”(下简称为“设计计算”)一文(见制冷学报1985年第3期),首次考虑了中间补气过程始末螺杆压缩机容积的变化,从而提出了整个压缩过程可分成一级压缩、等容绝热充气、等压放气和二级压缩四个阶段的假说,见图1。这在带经济器制冷循环节能本质的定量分析方面,应该说是更进了一步。然而,文中关于压缩机耗功的求法,值得商讨。“设计计算”一文认为,压缩气体消耗的机械功包括三部分,即一级压缩过程、二级压缩过程的技术功和
“Process Analysis and System Design Calculation of Economical Screw Refrigeration Compressor” (hereinafter referred to as “Design Calculation”) (see Journal of Refrigeration, No. 3, 1985), for the first time, the volume of screw compressor This paper proposes a hypothesis that the whole compression process can be divided into four stages: first stage compression, isothermal adiabatic inflation, isobaric outgassing and second stage compression. This is a further step in the quantitative analysis of the nature of economizer refrigeration cycles. However, the article on the compressor work well, it is worth discussing. The article entitled “Design Calculation” holds that the mechanical work of compressed gas consumption consists of three parts, that is, the first stage compression process and the second stage compression process.
