Embodiment Construction
[0100] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0101] figure 1 It exemplarily shows a schematic diagram of a system architecture applicable to the embodiment of the present invention, as shown in figure 1As shown, the system architecture applicable to the embodiment of the present invention includes a water system control device 101 and a water system 102. The water system 102 includes multiple sets of parallel pumps, such as cold and warm pump sets and cooling pump sets in the water system. A set of parallel pumps includes at least one pump, and all the pumps included in a set of parallel pumps are in parallel relationship. A grou...

The embodiment of the invention relates to the technical field of energy sources and energy conservation, in particular to a control method and device for a water system. The control method and device are used for saving energy of the water system. The control method includes the steps that the required flow which a set of parallel pumps need to meet in the next cycle of the water system is obtained; optimization calculation is conducted according to the required flow and constraint conditions, and pumps, needing to be in a working state, in the set of parallel pumps in the next cycle are determined, wherein the pumps meet the constraint conditions, and the total power of the pumps, needing to be in the working state, in the set of parallel pumps in the next cycle is the lowest; and when variable frequency pumps exist in the pumps, needing to be in the working state, in the set of parallel pumps in the next cycle, operation parameters of each variable frequency pump, needing to be in the working state, in the set of parallel pumps in the next cycle are determined. The constraint conditions at least comprise the condition that the total flow of the pumps, needing to be in the working state, in the set of parallel pumps in the next cycle meets the required flow.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of energy and energy saving, and in particular to a water system control method and device. Background technique [0002] The water system plays an important role in many fields, such as the water system in the central air-conditioning system, and there are multiple pumps in the water system. Since the design must be designed according to the maximum load, and the safety factor must also be considered, so in reality, the water system in the air conditioner does not operate at full load most of the time. According to statistics from relevant departments, the central air conditioning system has About 80% of the time is running below 75% low load. The current situation is that the water system of most central air conditioners adopts a constant flow system. When the load is low, the water volume is often too large, which causes a great waste of energy. [0003] With energy shortages, glob...
