[Abstract]:The national patent "full flow and high efficiency variable frequency speed regulation water supply method" (patent no. ZL200610057595.X.2006) and "secondary water supply front equipment and its control method" (patent no. ZL200810306080.8.2008) are new energy-saving water supply technology for building water supply.The first patent solves the problem that the current variable frequency speed regulating feed water technology works inefficiently in the state of low flow water supply, and saves the energy consumption of water supply by 25% and 40% compared with the ordinary variable frequency speed regulating feedwater pump. If popularized in the whole country, the power can be saved by 6.03 billion kW per year.The second patent solves the problem of water supply safety risk increased by ordinary non-negative pressure water supply equipment, and optimizes the energy saving effect. If popularized and used nationwide, the electricity can be saved by 10.04 billion kW per year.The market sales of construction water supply equipment in China reach 18 billion ~ 21 billion yuan each year. The two patents provide the development direction for energy saving optimization of water supply technology, and the colleagues have a good market development prospect.According to the working principle of centrifugal pump, this paper studies the influence of variable voltage frequency conversion and constant pressure frequency conversion on the lower limit value of high efficiency variable frequency pump.Combined with the hydraulic characteristics of the water supply system of building, the energy saving effect of the water supply equipment with high efficiency and frequency conversion is evaluated, and the influence of the superimposed pressure water supply technology on the energy saving effect of the water supply system is studied by using the water supply efficiency coefficient of the system.On the basis of the principle of system efficiency coefficient, this paper qualitatively studies the safety reliability and energy saving of different feed water supply systems, and studies the effect of superimposed pressure water supply on the working efficiency of main feed water pump.According to the comprehensive evaluation of equipment cost, this paper puts forward the experimental model for testing the efficiency coefficient of water supply system for different types of water supply equipment, and studies the market promotion route suitable for the two technologies in view of the characteristics of two water supply energy saving technologies.The research results include: (1) this paper theoretically proves that the energy saving effect of full flow high efficiency variable frequency speed regulating water supply equipment is better than that of general frequency conversion speed regulating water supply equipment.It is proved that the secondary water supply front-end equipment is more energy efficient than the general non-negative pressure water supply equipment, and the pump matching forms of the is series vertical pumps and DL series vertical pumps are compiled to prove that the secondary water supply front equipment is more energy efficient than the general non-negative pressure water supply equipment.The experimental model of comparing the efficiency coefficient of water supply system with different water supply equipment is put forward. The two secondary water supply energy-saving technologies have broad application prospects and are suitable for establishing professional operation companies.Through the EMC(energy management contractitioning) contract energy management model for commercial promotion.
