集中供热、热电联产是能量合理利用的有效方法,在具体实施这一方案时,热能输送管网的参数选择,是重要的环节之一。如果选择不当,将会造成达不到有效用能的目的。对于这个问题早有过深入的讨论和解决办法,但往往注意到能量的数量一面,或者多少考虑压降的问题,而忍视能量质的一面。本文较为深入 Centralized heating and combined heat and power are effective methods for the rational use of energy. In the implementation of this plan, the selection of the parameters of the heat transmission pipe network is one of the important links. If you choose improperly, you will not achieve the purpose of effective use. There has long been an in-depth discussion and solution to this problem, but often the attention is paid to the amount of energy, or to consider the issue of pressure drop, and to tolerate the qualitative side of energy.
