The embodiment of the invention provides an air conditioner control method, a server and an air conditioner system, and relates to the technical field of air conditioners. Control over the running state of an air conditioner can be achieved without a user, and intelligent air conditioner control is achieved. The air conditioner control method comprises the steps that input parameters and output parameters of a training sample are determined; a neural network mathematic model showing the mapping relation of the input parameters and the output parameters of the training sample is obtained; the tested training sample is obtained under the preset conditions; the tested training sample is substituted into the mathematic model to conduct neural network training, and a neural network control system is obtained; and the neural network control system is configured to the air conditioner so that the air conditioner can collect the real-time input parameters, the input parameters are input into the neural network control system, the real-time output parameters are calculated, and running of the air conditioner is controlled through the real-time output parameters. The air conditioner control method, the server and the air conditioner system are used for air conditioner control.
