正确设计集中供热负荷和合理选择循环水泵对采暖节能有明显的效果。 一、用连续供暖代替间歇供暖 北方采暖采用间歇供暖与连续供暖到底何者节能,多年来有着争论。由于我国长期来采用的不合理的间歇供暖管理制度很难改变,使许多设计部门形成不成文的法规,即:如保证连续运行就按规范计算;而如间歇运行则增加30％的间歇附加连续供暖和间歇供暖的设计负荷的比取为1∶1.3,或者说间歇供暖的供热量比连续供暖增大30％,可是间歇供暖的运行时间却比连续供暖的时间缩短50％以上,因而给人以间歇供暖比连续供暖节能的错误印象。
Correctly designing centralized heating load and choosing a circulating pump reasonably have obvious effects on heating and energy saving. First, the use of continuous heating instead of intermittent heating North heating using intermittent heating and continuous heating in the end what energy, has been argued for many years. Because the unreasonable intermittent heating management system used in China has been difficult to change for a long time, many design departments have formed unwritten regulations, that is, if they are guaranteed to run continuously, they will be calculated according to the specifications; and if they are intermittent operations, they will be increased by 30%. The design load ratio for heating and intermittent heating is 1:1.3, or the heating rate for intermittent heating is 30% higher than that for continuous heating, but the operating time for intermittent heating is shorter than that for continuous heating by more than 50%. The false impression that people use intermittent heating to save energy over continuous heating.
