METHOD OF DETERMINING THE OPTIMAL OBJECT HEATING TIME Russian patent published in 2018 - IPC F24D19/10 

FIELD: measurement technology.

SUBSTANCE: invention relates to methods for determining the optimum heating time of an object from a minimum permissible temperature to optimally comfortable one for a given object at the right time. Method for determining the optimum heating time of an object includes determining the necessary thermophysical characteristics of the object to find the heating and cooling time constant for the object by the method of least squares with the use of experimental data obtained during the 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_heat=P_cons/P_nom, where t_op – time of active operation of the heat supply system for the time t_heat, P_cons – average power consumption, P_nom – nominal power of the heat 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 allows to determine the optimum object heating time without using external climatic equipment and to increase the efficiency of the energy-saving mode and controllability of the autonomous heat supply system due to a more precise determination of the moment when the heat supply system is switched on to active work.
