Energy saving amount determination method and device for heating energy-saving reconstruction project

Abstract

The invention discloses an energy saving amount determination method and device for a heating energy-saving reconstruction project. The method comprises the steps that first, mathematical relationships between energy consumption accumulation values and indoor and outdoor temperature difference time number accumulation values in a whole heating period before and after project reconstruction are determined respectively; an ideal indoor and outdoor temperature difference time number accumulation value under an ideal condition in a heating period is determined; and finally, the energy saving amount in the heating period is calculated according to the two mathematical relationships determined before and after project reconstruction and the ideal indoor and outdoor temperature difference time number accumulation value. According to the method and the device, the heating energy consumptions before and after energy saving reconstruction are corrected to the same ideal condition, then the period energy saving amount is calculated according to the heating energy consumption correction value before and after reconstruction, and therefore the problem that the result error of the period energysaving amount is large due to the fact that the outdoor temperatures before and after energy saving reconstruction are different, or the heating quality is substandard can be avoided.

Description

technical field [0001] The present invention relates to heating energy saving, and more specifically relates to a method and device for determining energy saving of heating energy saving transformation projects. Background technique [0002] Climate compensation section technology is a heating and energy-saving technology that uses optimal adjustment technology to adjust heat supply in time according to outdoor temperature changes, so as to ensure that the indoor temperature remains at the standard temperature. This technology avoids energy waste caused by excessive indoor heating temperature and saves energy. The effect is remarkable and the promotion area is large. With the large-scale implementation of the contract energy management model, accurate verification of project energy saving has become an urgent demand in the market. At present, the energy saving of this type of project is generally determined by the total energy consumption reduction in the heating season bef...

AI Technical Summary

Problems solved by technology

[0003] (1) It cannot solve the error problem caused by the difference of climate parameters before and after the transformation

Heating energy consumption is greatly affected by changes in the external climate, and the external climate parameters before and after the transformation cannot be completely the same, resulting in inaccurate verification methods for energy saving of the project, and frequent disputes

[0004] (2) It cannot solve the error problem caused by the substandard heating quality after the transformation

If after the energy-saving renovation, the energy-saving company lowers the indoor heating temperature, resulting in the heating temperature not meeting the standard, it will lead to greater energy saving. The current energy-saving verification method cannot make up for this loophole
