【摘要】 高层建筑二次供水系统节能是建筑节能的重要组成部分,尤其对于供水能耗占比较大的住宅建筑具有明显的节能意义。变频恒压变流量控制供水,通常在供水设备出水总管上采集压力信号(系统前端恒压),相对容易实现,三十多年来在我国得到广泛应用。但这种供水方式在用水低峰时段与用户实际用水需求不匹配,管网压力富余造成能源浪费。而变频变压变流量控制供水,动态采集末端用户压力信息(系统动态末端恒压),充分节省系统流量变化过程中的富余水头,数字化、智能化程度更高,节能效果优于目前普遍采用的恒压变流量供水系统,代表着水泵变频调速节能供水技术的发展方向,应用前景广阔。更多还原

【Abstract】 Energy saving of secondary water supply system in high-rise buildings is an important part of building energy saving,especially for residential buildings with large energy consumption has obvious energy saving significance.Frequency conversion constant pressure variable flow control water supply,usually in the water supply equipment outlet main collection pressure signal(front-end system constant pressure),relatively easy to achieve,more than 30 years in China has been widely used.However,this water supply method does not match the actual water demand of users during the low peak period,and the pressure surplus of pipe network leads to energy waste.And variable frequency variable voltage flow control water supply,dynamic acquisition terminal user pressure information(system dynamic end constant pressure),fully save the rich head system flow change process,digital,intelligent degree is higher,energy saving effect is better than the commonly used constant pressure variable flow water supply system,represents the water pump frequency conversion the development direction of water saving water supply technology,broad application prospect.更多还原
