Description

Home energy consumption and indoor environment information feedback system based on regional energy consumption regulation

technical field

The invention relates to the technical field of energy consumption management, more specifically, it relates to a home energy consumption and indoor environment information feedback system based on regional energy consumption adjustment.

Background technique

With increasing global energy demand over the past few decades, declining available fossil fuels, and growing evidence of global warming, leveraging energy flexibility in buildings is often part of the solution to mitigate future demand-responsive energy systems. (electricity, district heating and gas grids) are some of the upcoming challenges. Among them, the adjustability of the HVAC system (such as heating/cooling/ventilation) provides the possibility for flexible energy use and alleviating the power supply problem. At present, the gap between the peak and valley loads of the grid is large, not only in developed countries but also in developing countries, resulting in higher network losses and shorter equipment life.

Feedback is a way to gently encourage residents to adjust their behavior based on information about their own energy use. Among a range of intervention methods, normative feedback has received widespread attention for its feasibility and effectiveness in terms of energy conservation, residents tend to pay more attention to other people's energy consumption after receiving household energy reports containing social normative information, Change your energy usage behavior. In previous experiments, we found that feedback is a powerful tool to curb electricity consumption, and in experiments, the average air conditioning usage of residents who received the feedback was significantly reduced. In foreign countries, the research on feedback to reduce energy consumption has proved that feedback is a feasible technical means. However, the traditional feedback only involves household energy consumption information, and the content of the feedback information is relatively narrow. The lack of information on the household indoor environment will lead to incomplete information received by users, resulting in incomplete judgments on the current indoor thermal environment and thermal comfort.

The home energy consumption and indoor environment information feedback system based on regional energy consumption adjustment provided by the present invention utilizes the flexible adjustment of the HVAC equipment in the residence, and achieves the initiative to reduce energy consumption on the demand side by providing normative feedback to users The purpose is to alleviate the peak power consumption and reduce the peak and valley load of the power grid. But different from ordinary normative feedback, we also feed back the temperature and humidity parameters inside the house, and calculate the appropriate temperature range according to the thermal comfort requirements in the ASHRAE55 standard. Therefore, the purpose of this device is to protect the house Under the premise of thermal comfort for users, reduce the air-conditioning energy consumption of users with high energy consumption, avoid waste of energy consumption, and make regional energy allocation more balanced.
