Metering Heating System Operation Adjustment Were Discussed

Long-term since, our country has been using traditional heating mode, namely outdoor temperature calculation according to the total quantity of heat, and thus for heating value adjustment. This kind of traditional regulating mode, users themselves unable to heating adjustment, which is passive acceptance. But with the development of society and economy and the improvement of people's living standard, people to comfort requirements are becoming more and more high and hope to be in your home in through to install adjusting device, according to their own needs to adjust oneself the home is implemented at room temperature, metering heating. But if metering heating the unceasing development, the traditional centralized heat-supply operation adjustment mode will not match with new heating mode, therefore, we need to study the new operation adjustment metering heating ways to adapt to pattern.This paper from the user should heat Angle, analysis and calculation of the traditional analysis of household metering system of heating of the heat load, affect indoor design the main factors, and compare it with the traditional distinction between thermal load calculation, of which mainly calculated metering heating system to the thermal load the influence of hot load between families pass several factors and influence high-rise building heating heat load calculation of the main factors. Then introduces several kinds of typical suitable for network operation adjustment modes, and analyzes the advantages and disadvantages between them, and mainly introduces a kind of household metering heating system applicable to the new regulation method-heat adjustment method, this paper introduces the basic concept and basic knowledge, and related the heat load and equipment selection aspects of the calculation, this chapter introduces several kinds of typical household metering equipment principle and application.Again, this paper introduced the nerve network, introduces relevant basic knowledge of neural network learning the rules related to below, an artificial nerve network thermal load forecasting laid a theoretical foundation. And according to the introduction of artificial neural network theory, mainly introduces predicted the BP network's concept, the characteristic and the modeling, BP network based on the thermal load forecasting, and puts forward steps and algorithm used by the heat load forecasting the neural network model, in this chapter also briefly introduced the network predictor for into important auxiliary tools -- MATLAB neural network toolbox. Refer to the foregoing two chapters of neural network with the basic theory, taiyuan collected the chengxi heat-2010 2009 annual and 2010-2011 annual two heating of historical data as the basis, constructing basic forecasting model, and the BP neural network for short-term hot load forecasting, including normal weekday heat load forecast, the thermal load forecast and hours working heat load forecast three parts. By forecasting results that will neural network used in thermal load forecasting can get short term is a more satisfactory results, thus the BP network application in short-term heat load is feasible, and household metering heating system for short-term hot load forecasting method with a corresponding theory.
