高温热水采暖比蒸气采暖优越得多,但它带来了新问题。其主要通病之一就是凡暖气片组位于热水主管上游的比下游的要热得多,影响了供热效果。 1973～1977年采暖期间,我在本厂从事采暖管道调试工作,对此进行了探索。我们在接暖气片组的管径上找到了问题所在,即现在生产的最小管子D_(?)15对暖气片组来说往往过大。 High-temperature hot water heating is much better than steam heating, but it brings new problems. One of the common problems is that the radiator group is located much hotter upstream than the hot water pipe, affecting the heating effect. During the period of heating from 1973 to 1977, I was engaged in the commissioning of heating pipes in our factory, which was explored. We found the problem in the diameter of the radiator group, that is, the smallest pipe D_(15) produced now is often too large for the radiator group.
