METHOD FOR DETERMINING THE OPTIMAL HEATING TIME OF THE HEATING OBJECT Russian patent published in 2019 - IPC F24D19/10 

FIELD: physics.

SUBSTANCE: invention relates to methods of determining optimum heating time of an object from a minimum allowable temperature to optimally comfortable for a given object to a desired moment in time. Method of determining the optimum object heating time consists in determining the required thermophysical characteristics of the object in order to find the heating and cooling time constant of the object using the method of least squares using experimental data obtained during heating of the object. Then the dependence of the ambient temperature on the coefficient of active work of the heat supply system is determined. Coefficient of active work of the heat supply system is determined by the following formula: K_a = t_op/t_pod = P_exp/P_ust, where K_a is coefficient of active operation of heat supply system, t_op – time of active operation of heat supply system during time t_pod, P_exp is average consumed power, P_ust – rated power of heat supply source. Further, the dependence of the object heating time on the ambient temperature and, using the obtained data, the dependence of the object heating time at a certain instant of time on the coefficient of active operation of the heat supply system are determined, while if there is no coefficient of active work of the heat supply system, the determination of the optimum object heating time is determined by the dependence of the object cooling time on the ambient temperature, then the optimum object heating time is obtained depending on the ambient temperature.

EFFECT: method enables to determine optimum heating time of an object without using external climatic equipment and to increase efficiency of energy saving mode and controllability of autonomous heat supply system due to more accurate determination of the moment of heat supply system activation into active operation.
