Building energy saving centralized control method

Abstract

The invention discloses a building energy saving centralized control method, comprising: S1, leading electricity-using equipment to enter an energy saving rate test stage and testing energy saving rate; S2, judging whether the energy saving rate is larger than or equal to the preset energy saving rate, if yes, executing S4, and if no, executing S3; S3, revising control parameters of the electronic equipment or replacing the electronic equipment and returning to S1; and S4, leading electricity-using equipment to enter a normal working stage until the next energy saving rate test stage. In the energy saving rate test stage, the electricity-using equipment works in an energy saving mode and a non-energy saving mode in an alternative way, and energy saving rate is calculated according to energy consumption under two working modes. Compared with the prior art, the invention can test energy saving situation of electricity-using equipment at any time, so as to discover electricity-using equipment with poor energy saving effect in time according to the test result, thus being favorable for effectively avoiding long-term energy waste and having high test accuracy.

Description

technical field [0001] The invention relates to a building energy-saving centralized control method, in particular to a device for real-time monitoring and detection of the energy-saving situation of building electromechanical equipment. Background technique [0002] With the development of a conservation-minded society, large-scale equipment energy-saving renovations are underway, but there is a lack of effective energy-efficiency testing methods for the effect of energy-saving renovations. In the prior art, once the energy-saving equipment of a building is installed, it is always in working condition without any monitoring of its energy consumption. However, if the control parameters of energy-saving equipment are set unreasonably, or some energy-saving equipment will age or fail after long-term use, these factors will lead to a sharp increase in energy consumption of energy-saving equipment, resulting in serious energy waste. On the contrary, if these problematic devices...

AI Technical Summary

Problems solved by technology

[0004] 1. The energy-saving status of the electrical equipment in the building cannot be monitored and tested at any time. Therefore, the electrical equipment with poor energy-saving effect cannot be found in time according to the test results, resulting in long-term energy waste;

[0005] 2. The annual energy consumption is used to evaluate the energy-saving performance of electrical equipment. The evaluation results are not accurate and are easily affected by uncertain factors.
