Energy saving techniques of pressurized water supply systems in buidings

The dynamic energy saving techniques of building pressurized water supply system include the energy saving of terminal users,transporting and distributing pipes,and pressurized water supply equipments.The energy saving of terminal users mainly consists of the control of invalid water release point and reducing the usage of backflow preventer at the least favorable point.The energy saving of transporting and distributing pipes involves selecting the pipe diameter based on economic velocity,decreasing the losses in pipe network,and using different pumps for vertical division.The energy saving of pressurized water supply equipments comprises of taking full advantage of the city water supply pressure,cutting down the over-high water head of watering device with frequency conversion,and adopting the water supply mode with high operational efficiency.
