The metering technology of temperature method is based on the indoor temperaturemeasurement, it can effectively solve some problems, which are the heat transfer betweenthe household and the high cost of heating measurement transformation, etc. The thesisanalyses and studies the problems that the temperature method exist the shortcoming inpractice.Firstly, according to the characteristics that temperature method needs do long-termmonitoring to the indoor temperature, the thesis puts forward that internal wall astemperature measuring object. After experimental analysis, the thesis confirms the indoortemperature correction coefficient: the nightside room correction coefficient is0.96, andthe sun room correction coefficient is1. Secondly, according to the measured data and theFluent simulation, which is analyses that typical indoor cold and heat source has effect onthe temperature and obtain that indoor temperature measurement should be without0.5munder200W of household appliances. For the high-power electrical appliances, openwindows and other phenomena, the thesis puts forward that should adopt the eliminationinterference method to calculate and verify its feasibility. Finally, according to theinfluence of the building’s natural factors on the building indoor temperature, the thesisuses the DeST software for simulating and analyzing, which is establish the average indoortemperature correction table and optimize direct calculation mathematical model. Aftercalculating, the optimized error is5.8%.After studying on the measurement method, the influence factors and mathematicalmodel of temperature method, the thesis combines the actual measurement and numericalsimulation to verify its accuracy and feasibility, and it provides the reference in theengineering practice for the temperature metering.
