The invention relates to an intelligent control method for heat dissipation of an air conditioner of a new energy commercial bus. Comprising the steps that an intelligent controller in the air conditioner heat dissipation intelligent system collects the supercooling degree x of an air conditioner refrigeration system through a vehicle-mounted local area network CAN bus communication port, and collects the air conditioner air outlet temperature z and the in-vehicle environment temperature y through an AD sampling port and a temperature sensor; the change x of the supercooling degree is calculated through the supercooling degree x, and then the change rate x'of the supercooling degree is calculated; an expected temperature difference value w is calculated through the air outlet temperature z and the in-vehicle environment temperature y, and then the temperature difference coefficient gamma is calculated; according to the maximum output air volume Fmax and the minimum output air volume Fmin of the electronic fan, the temperature difference value w of the in-vehicle environment and the air conditioner air outlet and the preset h-level adjusting quantity of the fan, the minimum output air volume variation f of the electronic fan is calculated; and according to the supercooling degree change rate, the expected temperature difference coefficient and the minimum air volume variation, the air volume required for air conditioner heat dissipation is calculated, and therefore the heat dissipation efficiency of the commercial bus air conditioner heat dissipation system is improved, and energy consumption is reduced.
