The invention provides an energy-saving control system of a central air conditioner. The energy-saving control system comprises an air conditioner tail end, a tail end water supply and return communicating pipeline, a temperature and humidity sensor, an electric regulating valve, a controller (1), a water return pump, a flow sensor, a controller (2) and a refrigerating unit. The temperature and humidity sensor is electrically connected with the controller (1), the controller (1) is electrically connected with the electric control valve, the flow sensor is electrically connected with the controller (2), and the controller (2) is electrically connected with the refrigerating unit. The energy-saving control system of the central air conditioner aims to solve the problems of excessive dehumidification, large indoor temperature variation amplitude and high energy consumption of the central air conditioner. The system can reuse the return water heat at the tail end of the air conditioner, adjust the water supply te
