大庆石油学院机械系能源工程研究室近期展示出五项节能技术新成果。它们是:“三箱”模型测试技术;用能系统评价与诊断技术;(工艺型)总能系统技术;NGL回收装置能量分析软件包;高效热泵节能技术。这五项新技术是对油气集输系统进行(火用)分析研究而得到的。由白箱、灰箱、黑箱及其组合而成的“三箱”测试方法,可以准 Daqing Petroleum Institute of Mechanical Engineering Department of Energy Engineering recently demonstrated five new achievements in energy-saving technologies. They are: “Three Boxes” model test technology; Energy system evaluation and diagnosis technology; (process type) total energy system; NGL recovery device energy analysis software package; efficient heat pump energy saving technology. These five new technologies are based on exergy analysis of oil and gas gathering and transportation systems. By the white box, gray box, black box and its combination of “three boxes” test method, you can associate
