A method for regulating the supply water temperature of a heating system based on weighted perturbations

Abstract

The application discloses a kind of based on the adjustment method of heating system water temperature of weighting disturbance, consider the attenuation and delay characteristics of each thermal disturbance to room temperature influence under the action of building thermal inertia, with the weighted form of outdoor temperature and heating system water temperature reflect each thermal disturbance to current room temperature influence of current and previous historical time.Based on the linear characteristics of room as heat system, by the interrelation of each thermal disturbance to room temperature influence, a new quality regulation mode of heating system is constructed.The application is suitable for the case that indoor and outdoor ventilation is relatively small in winter in residential room, the constructed regulation mode based on weighting disturbance can significantly reduce the water temperature of heating system, realize low-temperature operation of heating system;At the same time, room heating temperature can be controlled within a reasonable range, effectively avoid the problem of excessive heating.From the two aspects of energy grade and energy consumption quantity, the energy utilization efficiency of heating system can be significantly improved, and the operation energy consumption is reduced.
