我国城镇建筑能耗已达社会总能耗的30%,其中供热采暖能耗在我国北方地区高达建筑总能耗的一半以上。为改善传统供热行业热耗浪费、运行电耗过高等问题,本文提出可调喷射泵在供热系统管网改造中的具体应用。工程实践分析表明:基于可调喷射泵技术的新型供热管网系统传统集中供热系统节能效果显著。每到冬天,供暖都是老百姓口中热议的话题。而如何提升供暖效果,一直是行业的研究重点。众所周知,供暖网路中,任何一个热用户流量的改变, China’s urban construction energy consumption has reached 30% of the total social energy consumption, of which heating and heating energy consumption in northern China up to more than half of the total building energy consumption. In order to improve the traditional heating industry waste heat consumption, running high power consumption and other issues, this paper proposes adjustable jet pump pipe network in the heating system for the specific application. The engineering practice shows that the energy saving effect of the traditional central heating system based on the adjustable jet pump technology is remarkable. Every winter, heating is the hot topic in the mouth of ordinary people. How to improve the heating effect has always been the focus of the industry. As we all know, the heating network, any change of hot user traffic,
