【英文篇名】 Energy recovering dual-pump for atmospheric pressure boiler heating systems 【作者中文名】 龚冬柏; 郑官振; 【作者英文名】 Gong Dongbai Zheng Guanzhen; 【作者单位】 大连市旅顺民用建筑设计院; 大连市建筑设计研究院; 【文献出处】 暖通空调, HV 位能回收; 常压锅炉; 【英文关键词】 dual-pump; potential enersy recovery; atmospheric pressure boiler; 【摘要】 高层建筑采用常压锅炉为热源时,热水被泵送到建筑物最高处,大量位能被白白地浪费。为回收这部分位能,研制了一种称为双水泵的设备,它不仅能回收一定量的位能,而且能防止突然停电时出现水锤及因回水阀来不及关闭而产生的跑水问题。 【英文摘要】 In an atmospheric pressure boiler heating system especially when used in a tall building,the energy of position is largely wasted.Describes a machine named dual-pump which, consisting of a pump and a hydroturbine,can not only recover the potential energy,but also prevent water hammer when sudden power cut off and water run out before the valve shutted.
