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.

Abstract

The invention discloses a building energy-saving centralized control method, which includes: S1: using electrical equipment to enter the energy-saving rate detection stage, and detecting the energy-saving rate; S2: judging whether the detected energy-saving rate is greater than or equal to the preset energy-saving rate, if it is judged to be ' If yes', execute step S4, if judged as 'no', execute step S3; S3: modify the control parameters of the electrical equipment or replace the electrical equipment, and then return to step S1; and S4: use the electrical equipment to enter the normal working stage , until the next energy-saving rate detection stage. In the energy-saving detection stage, the electrical equipment alternately works in the energy-saving and non-energy-saving working modes, and calculates the energy-saving efficiency according to the energy consumption data in the two working modes. Compared with the prior art, the present invention can detect the energy-saving status of electrical equipment at any time, so that electrical equipment with poor energy-saving effect can be found in time according to the detection results, which is beneficial to effectively prevent long-term energy waste, and at the same time, the detection is accurate high sex.

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...
