Air-conditioning fan

Disclosed is an air conditioning fan, which consists of a case body and a blower, a water tank, a PTC heater as well as a compression type refrigerating machine in the case body and is characterized in that the evaporator of the compression type refrigerating machine is arranged in the water tank which is made of metal materials with excellent heat conducting performance; the inner side of an air filter in air inlet at back surface of the case body is provided with a water-cooling type air cooler; the water tank is also provided with the energy transducer of an ultrasonic atomizing device. For cooling in summer, air entering from the air inlet of the air conditioning fan exchanges heat and is cooled for three times before being discharged from the air outlet, making the temperature of air near the air outlet of the air conditioning fan at the level which makes the human body feel comfortable and effectively solving the problems of difficult ice water supply and insignificant cooling effect in refrigeration work of various prior air conditioning fans.
