The embodiment of the invention provides an air conditioner energy-saving control method and device based on the comfort level. The control method comprises the following steps that season informationand passenger flow density information are used as adjusting strategy factors, and an energy-saving control strategy of an air conditioner system of a waiting room is adjusted; and the comfort levelof passengers is taken as a feedback strategy factor, the energy-saving control strategy of the air conditioner is optimized, and the temperature and the air quality of the waiting room are adjusted in real time. According to the air conditioner energy-saving control method and device based on the comfort level, based on the purposes of reducing the labor intensity of workers, improving the comfort level of the passengers, saving energy and reducing consumption, multiple operation environment factors are fully considered, the season, the temperature, the passenger flow density, the CO2 concentration and other strategy factors are combined, and the comfort level of the passengers is calculated so as to optimize the energy-saving control strategy suitable for a passenger station, so that itis ensured that the total electricity consumption of the air conditioner system is effectively reduced while the comfort transfer waiting environment is provided for the passengers, energy-saving operation and intelligent control of the air conditioner are realized, and the purposes of saving the energy, reducing the consumption, reducing the staff number and enhancing the efficiency and improvingthe intelligent management level of the station are achieved.
