The invention relates to a cluster control method for computer room precise air conditioners. The cluster control method includes the steps that a control host is arranged in multiple control regions, and at least one controlled air conditioner and at least two temperature probes are arranged in any controlled region; in each region, the temperature probes correspond to the controlled air conditioners, and when a temperature parameter collected by any of the temperature probes corresponding to the controlled air conditioners exceeds a certain upper limit threshold value for certain time, the corresponding controlled air conditioners are turned on; when the temperature parameters collected by all the temperature probes are below a certain lower limit threshold value for certain time, the corresponding controlled air conditioners are turned off. The control method can effectively reduce the starting frequency of a compressor and avoid frequent starting, and the air conditioners are in a fully closed state for most of time each day to save energy. The running time after single starting of the compressor is prolonged, the energy efficiency ratio is increased, and the service life is prolonged. Data will be transmitted to a far end in real time, and the air conditioners can be manually operated to run or shut down at the far end.
