PURPOSE: A blower fan for an air conditioner is provided to improve heat exchange efficiency by injecting water to a heat exchanger in rotating the fan with forming plural passages and a water supply unit, and to reduce noise by restricting excessive rotation of the fan. CONSTITUTION: Plural water passages(14) are formed from a hub to a tip and a trailing edge in a blade part of a blower fan(12), and a water supply unit is connected to the water passages to supply water. The water supply unit has a water tank(21) storing water, a water supply pipe(22) connecting the water tank to the water passage of the fan, and a valve(23) installed in the outlet of the water tank and opened to feed water from the water tank to the water supply pipe in rotating the fan. Heat exchange efficiency is improved with injecting water in rotating the fan, and noise is reduced.
