摘 要：The existing parallel type pressurized water supply pipeline of high-rise buildings has been improved to build energy-saving high-rise building water supply systems.Series-parallel combined constant pressure water supply pipeline is designed.Antipollution high water tank is reasonably installed above the middle area of the building to supply water for the middle area high water tank and supply pressurized water by water pumps for high-rise district.And PLC control system is designed to control the work efficiency of the water pumps according to the sensor feedback information.Verified by calculation and simulation,series-parallel combined constant pressure water supply pipeline is better than parallel water supply pipes in saving the energy which is about the middle-Hybrid phase consumption of the latter.PLC control is simulated and the results show that PLC can effectively control the water supply system to ensure stable water pressure so as to save energy.
