The invention provides an elevator air-conditioning control method, which adopts the following elevator air-conditioning control system comprising an elevator and an air-conditioning system, wherein the air-conditioning system comprises a compressor, an evaporating fan, a cooling fan and a fresh air door; the elevator air-conditioning control system also comprises an air-conditioning controller and an elevator controller; the cooling fan and the compressor are connected with the air-conditioning controller and controlled by the air-conditioning controller, and the evaporating fan is connected with the elevator controller and controlled by the elevator controller. The elevator controller detects the running condition of the elevator to control on/off of the evaporating fan, and the air controller controls the working state of the air-conditioning system according to the on/off condition of the evaporating fan. According to the elevator air-conditioning control method, control of the evaporating fan and the control of the air-conditioning system are separated, so that an elevator air supply system and an elevator air-conditioning system can be independently controlled by combining with an actual running condition. Therefore, optimization on control is achieved; the riding comfort of the elevator is also improved, and energy consumption is saved.
