The invention relates to a constant-pressure variable-frequency water pump energy consumption prediction method, belongs to the technical field of water pump energy consumption calculation, and solvesthe problem that an efficient energy consumption calculation method and tool are lacked in the existing design stage. The method comprises the following steps that the flow of the water pump under the power frequency condition is obtained according to the lift characteristic and the equal efficiency characteristic of the water pump under the power frequency condition; Obtaining the efficiency ofthe water pump under the power frequency condition according to the flow of the water pump under the power frequency condition and the power frequency efficiency characteristic of the water pump; Obtaining the flow of the water pump after frequency conversion according to the lift of the water pump after frequency conversion and the equal efficiency characteristic of the water pump; And obtainingthe energy consumption of the water pump after frequency conversion according to the water pump efficiency under the power frequency condition, the lift of the water pump after frequency conversion and the flow of the water pump after frequency conversion. Energy consumption prediction after frequency conversion is achieved, and a basis is provided for water pump design in the design stage.
Description
Technical field [0001] The invention relates to the technical field of water pump energy consumption calculation, and in particular to a method and device for predicting energy consumption of a constant pressure variable frequency water pump. Background technique [0002] Building energy consumption accounts for about 30% of the total energy consumption of the whole society. As the country pays more and more attention to energy conservation and emission reduction, building energy conservation is gradually turning to total building energy consumption control. With the increasing number of high-rise buildings in China, the proportion of water supply system energy consumption in building energy consumption is gradually increasing. Simulation research on annual operating energy consumption of water supply system is particularly important for water supply system design under energy consumption indicators. [0003] The constant pressure variable frequency water supply technology changes ...
