A method and a device for collecting a condensed water to clean an air conditioner based on rotation speed regulation of a compressor are disclosed. A heat exchanger in the air conditioner is used for condensing water vapor inside the air conditioner into a liquid water, and thereby cleaning the dirt adhered on the surface of the heat exchanger. The step of condensing the water vapor into the liquid water comprises: determining a surface temperature for condensation of the heat exchanger as an expected temperature, on the basis of a current environment temperature and a current environment humidity of the air conditioner; regulating and maintaining the temperature of the heat exchanger at the expected temperature by regulating the rotation speed of the compressor in the air conditioner.
