Problems solved by technology
[0002] The frequency conversion water supply system is widely used in the secondary pressurized water supply system due to its unique constant pressure water supply characteristics. The large and medium-sized variable frequency water supply systems are non-stop 24 hours a day, 365 days a year, resulting in huge waste of electric energy
[0003] According to the characteristics of the water pump, when the flow rate is 0 (no load), the efficiency of the water pump is 0. At this time, the real-time power of the water pump is about 40% of the rated power (related to the performance of the water pump and the set water pressure). Downtime is more than causing a lot of waste of electric energy
[0004] In addition, the water pump is not an ideal work equipment. The real-time efficiency of the water pump changes with the flow rate. When the water flow is small (light load), the efficiency of the water pump is very low. If the water pump works inefficiently for a long time, it will also cause a lot of waste of electric energy.

The invention relates to a light-load shutdown variable frequency water supply system with distributed terminal energy storage. The system comprises at least one terminal energy storage unit and at least one light-load shutdown variable frequency water supply unit, wherein the terminal energy storage unit is used for providing sufficient shutdown pressure storage and water supply capacity for thewater supply system; and the light-load shutdown variable frequency water supply unit is used for carrying out constant-pressure water supply or light-load shutdown for the water supply system. According to the technical scheme provided by the invetnion, the idle work done when the water supply system is at an empty load and the low-efficiency working state at a light load are avoided, the operation efficiency of the water supply system is greatly improved, a large number of electric energy is saved, and meanwhile, the service life of the water supply system is prolonged.
Description
technical field [0001] The application belongs to the technical field of water supply equipment, and in particular relates to a light-load shutdown frequency conversion water supply system with distributed terminal energy storage. Background technique [0002] The frequency conversion water supply system is widely used in the secondary pressurized water supply system due to its unique constant pressure water supply characteristics. Most of the large and medium-sized frequency conversion water supply systems are non-stop 24 hours a day, 365 days a year, resulting in huge waste of electric energy. [0003] According to the characteristics of the water pump, when the flow rate is 0 (no load), the efficiency of the water pump is 0. At this time, the real-time power of the water pump is about 40% of the rated power (related to the performance of the water pump and the set water pressure). Downtime is more than causing a lot of waste of electrical energy. [0004] In addition, t...
