Energy-saving living water supply improvement method and system applying same

Abstract

The invention relates to an energy-saving water supply improvement method and a system for implementing the same, in particular to an energy-saving living water supply improvement method and the system applying the same. The energy-saving living water supply improvement method comprises the following steps: establishing a mechanism for automatically switching municipal pipe network water supply and water pool supply; when water supplied by a municipal pipe network exceeds or just satisfies the water demand of a customer pipe network, supplying the water to the customer pipe network with the municipal pipe network; and when the water supply pressure of the municipal pipe network water supply is less than the water consumption pressure of the customer pipe network, switching to supply the water with a water pool and simultaneously supplying water to the water pool with the municipal pipe network. In the energy-saving living water supply improvement method and the system applying the same, as the mechanism for automatically switching the municipal pipe network water supply and the water pool supply is established, not only the original pressure of a water supply line can be utilized, but also enough stored water can be utilized to relieve the pressure of peak flow rate without generating a negative pressure for the water supply line. Under the condition of one-region water supply, when the water is supplied by the water pool, if water pumps are configured rationally, energy cannot be saved, and if the water pump are configured irrationally, the energy can be saved to a certain extent after the water pumps are optimized; and if a plurality of regions are supplied with the water, the energy saving of middle and lower regions are not influenced.

Description

technical field [0001] The invention relates to a water supply energy-saving transformation method and a system for realizing the method, in particular to a domestic water supply energy-saving transformation method and a system applying the method. Background technique [0002] At present, the commonly used frequency conversion constant pressure water supply for domestic use, no matter whether the user uses water or not, the water pump will not stop, because when it is stopped, if there is water, the pump will accelerate for a certain period of time, which will cause the water supply pressure to be unstable, so there is no function of stopping the pump. Although the operating current is not large, the power consumption of uninterrupted operation throughout the year is very considerable. Therefore, there is a large waste of energy in this water supply system, that is, the water pressure of the municipal pipe network drops to 0 after entering the underground pool, and this ene...

[0004] Water supply mode 1 Since the water tank can effectively handle the water volume, that is, store the water volume during non-peak water consumption, the flow Q that the tap water pipeline can provide at this time 自 Greater than the amount of water Q required by the user 用 , (i.e. Q 自 >Q 用 ), while during the peak water use period Q 自 用 Timely release the stored water, so it can effectively protect the reliability of the user's water use. At the same time, because the water pipe is connected to the water pump through the water tank, the water pump will never generate negative pressure on the water pipe network, but the water pipe network The original pressure cannot be utilized by the water pump, which will inevitably result in a waste of energy

[0005] Water supply mode 2 although in Q 自 >Q 用 The original pressure of the pipe network can be used at times, but because there is no water storage device, it cannot meet the water consumption during the peak period, so it cannot ensure the reliability of the user's water use, and it will generate suction (negative pressure) on the water pipe network during the peak period of water consumption, so cannot be widely used
