Optimal stop time prediction model of floor-radiating heating system

The invention discloses an optimal stop time prediction model of a floor-radiating heating system and aims at providing an optimal stop time prediction model used for closing the floor-radiating heating system in advance according to predicted optimal stop time before habitants leave a room so as to achieve the energy-saving purpose on the premise that the comfort requirement of human is ensured. The regression equation of the optimal stop time prediction model is as follows: 1g(tstop) = 0.9698 + 0.1957 * deltaT-0.0468 * Tg + 0.012 * Tout, wherein the tstop represents optimal stop time, the deltaT represents room temperature change value, Tg represents target room temperature, and Tout represents outdoor temperature. According to the optimal stop time prediction model, several independent variables convenient to monitor are selected as regression variables, the prediction model is determined through regression analysis so as to achieve practicability of the prediction model. A prediction result obtained through multivariate regression analysis is higher in accuracy, a control system is simple, real-time control can be achieved, and the optimal stop time prediction model is suitable for control of a residential building heating system.
