而对于典型的双管系统，则由两条区域送风路径（一条用于热空气、一条用于冷空气）和一条区域回风路径组成。 - Abstract : discusses the relative electric power consumption for the single - and doublepipe system using frecluency control of the pumps , provides their values calculated for 18 cities in china and a formula to estimate the static payback period for actual systems and an example
文摘:探讨了循环泵变频调速时单管和双管系统的相对电耗，计算得出了18个城市的相对电耗值，给出了实际系统变频调速投资的静态回收年限计算公式和一算例。 - Heating centralized is an important thing in the north . whether this is implemented in a large scale has contributed to impove city modern level and ameliorate atmosphere environment . the traditional heating system are two - upright - pipe - parallel system , two - pipe system , single - pipe - stride system etc , whose calculation for heat charge is either by man or by ic installed on the caliduct . therefore , the problem arise that heat provided does n ' t accord with heat charge payed , not secure , and resident have to suffer much
传统的供暖系统有双立管水平式系统、全双管系统、单管跨越式系统等，其计费方式要么为人工计费，要么是利用安装在暖气片上的带电读卡器，这样存在着供热量与收费额匹配不准确、不安全等方面的问题，也使集中供热用户有苦难言。
