Abstract

The invention discloses an air conditioner and an attenuation compensation control method of a water fetching motor thereof, the air conditioner comprises a refrigerant circulation loop, a compressor, a water tank, the water fetching motor and a lower fan, and a controller is configured to control the lower fan to operate at the highest rotating speed when it is determined that the water level in the water tank is lower than a preset water level after the air conditioner is started to operate. Meanwhile, after the compressor is controlled to stop for a first preset time, a first operation parameter corresponding to the water fetching motor is obtained, whether mechanical attenuation happens to the water fetching motor or not is judged according to the first operation parameter, if yes, the set operation parameter of the water fetching motor is updated to conduct attenuation compensation on water level detection of the water fetching motor, and if not, the water fetching motor is stopped. The compressor and the lower fan are controlled according to the set operation parameters before updating, attenuation compensation can be carried out on water level detection of the water fetching motor, and the accuracy of water level detection is improved.

Description

technical field

[0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a method for controlling attenuation compensation of a water pumping motor. Background technique

[0002] In the current air conditioner industry, mobile air conditioners use a water pumping motor to remove water, and detect the current water level in the water tank by acquiring the speed of the water pumping motor, thereby replacing the physical water level switch and greatly reducing costs. It will cause mechanical fatigue and wear after long-term operation, resulting in a decrease in speed with the increase of wear and tear, which in turn affects the accuracy of water level detection, resulting in inaccurate water level detection. SUMMARY OF THE INVENTION

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the purpose of the present invention is to provide an attenuation co...
