The invention discloses an energy-saving control method for an air conditioning unit. The energy-saving control method comprises the steps that historical data are preprocessed and then stored; establishing a water pump energy consumption estimation model; the actual power Pa of a single water pump is used as a dependent variable, and independent variables are the water pump operation frequency F and the water pump rated power Pe; the actual numerical value of c is determined through fitting, and the default value of c is 2.8 c = 2.8; calculating the total power; based on a water pump energy consumption estimation model, the total power of a single water pump until N water pumps are within the upper and lower limits of the operation frequency is calculated, the switching critical frequency of parallel connection of the water pumps is determined, and a water pump operation energy consumption library is generated; during actual operation, the minimum total power Pt serves as the target, traversal query is condu
