Automation of Monitoring the Thermal Conditions in a Room

Статья в сборнике трудов конференции

Monitoring of thermal conditions in a separate room and a building is one of the most important practical tasks on the stage of building commissioning. The task can be solved by in-situ temperature measurement of and the results are calculated by a simple mathematical model. The model is a system of balance differential equations for average temperatures of a heater, air and internal boundary. The parameters of equations are heat-transfer coefficients of heaters, heat-transfer coefficients of internal and external boundary and heat capacitance of objects in a room. These parameters are calculated in a reverse problem. Non-steady-state situations appear with temperature changes in a room. The target values are calculated through the analysis of temperature dependence. The automated complex for this algorithm consists of a system of temperature sensors, a microcontroller, a radio data link and a hosting server. The system was tested in residential and production buildings, and the monitoring proved to be low-cost. The system also allows to measure heat energy input to high precision according to individual characteristics of a room and a heater. The accuracy is provided by experimental study of heat-transfer coefficients of heaters and statistical data analysis.
