The invention discloses an energy-saving control method and device used for a cooling tower and an air-conditioning system. The method comprises: detecting the wet bulb temperature of the cooling tower in the environment and the outlet water temperature of the cooling tower based on the starting or closing request of the cooling tower, calculating the difference value between the detected outlet water temperature and the wet bulb temperature, determining the relationship between the calculated difference value and the preset threshold value to obtain the corresponding determine result, adapting and adjusting the number of starting or closing water valve of the cooling tower, and/or the starting or closing form of the fan of the cooling tower, and realizing the energy-saving control of starting or closing the cooling tower. The energy-saving control method and device used for a cooling tower and the air-conditioning system can overcome the defects such as inflexible temperature regulation, low reliability, and
