The invention relates to the technical field of energy conservation of air conditioners, in particular to energy-saving equipment for an air conditioner, which comprises two drainage pipes arranged in parallel, a gap is reserved between the two drainage pipes, a plurality of water outlet holes are formed in the pipe walls of the drainage pipes, a first motor box is arranged at one end of each drainage pipe, and a motor is arranged in the first motor box; the motor is coaxially connected with the drainage pipe, and the drainage pipe is rotationally connected with the first motor box; the first motor box is fixed to a movable seat, the movable seat is in threaded connection to a lead screw through a nut, and a second motor box is arranged below the lead screw. When the energy-saving equipment for the air conditioner is used, water is sprayed on the condenser, heat on fins of the condenser and heat on the condensation pipe can be adsorbed, and therefore the efficiency of heat conversion of cold and hot media in the condenser is improved when the air conditioner conducts refrigeration, the operation power of an air conditioner compressor can be reduced, and the energy-saving effect is improved. And an energy-saving function is achieved for the operation of the air conditioner.
