Energy saving air-conditioning control system based on average heat sensing index and method thereof

An energy saving air-conditioning control system based on the Predicted Mean Vote (PMV), includes a controller, a PMV sensor, a CO2 concentration sensor, an outdoor enthalpy value sensor, an indoor enthalpy value sensor, a fresh air valve, a coil pipe cool water valve, and a fan transducer. The controller includes PMV control module, an energy saving control module. The PMV sensor, the CO2 concentration sensor, the indoor enthalpy value sensor), the outdoor enthalpy value sensor are connected to an analog input electric circuit of the controller. The fresh air valve, the cool water valve and the fan transducer are connected to the output electric circuit of the controller. The invention realizes environment PMV conditioning by applying fuzzy control method and realizes the improvement of air quality by monitoring CO2 concentration; thereby the system realizes the optimal combination of temperature comfort requirement and energy saving requirement.
