Therefore, the method for controlling the indoor air quality environment in the prior art has more problems in the aspects of system coordination, parameter monitoring, regulation and control basis, accuracy, reliability, comprehensiveness and the like of energy-saving management, and therefore, the generation of sick building syndrome cannot be effectively solved. However, a few multi-parameter coordination control systems in the prior art are based on energy consumption and environment monitoring, and lack a physiological index control basis for comprehensively reflecting the influence of indoor environment multi-parameters on human comfort and health, and the regulation and control precision of the system needs to be further improved.
