Comfort zone energy-saving optimization method based on indoor quality control model

The invention discloses a comfort zone energy-saving optimization method based on an indoor quality control model. The method comprises the steps of: establishing a quality and energy balance model ofan air-conditioned room; establishing the mass and energy balance model of the AHU; converting the output variable water and CO2 content of the established model into humidity and ppmV values; determining conveying temperature and flow constraints of the room and the AHU system according to the external environment volume flow of the room and the AHU system, the room input temperature, the room humidity and the pressure; dynamically constraining the valve; adopting time-varying constraints for temperature, humidity and air quality; adopting a PMV-PPD index to set a reasonable comfortable area; and setting objective functions of a comfort zone optimization method based on a model and a set point tracking method, optimizing the control variables, and giving out temperature, humidity and CO2content required when the
