Abstract: PURPOSE: A ceiling type air conditioner is provided to reduce noise and improve efficiency of the air conditioner by reducing generation of vertex flow between a bell mouse and a shroud by folding the end part of the bell mouth to form the bell mouth in the shape of sine function. CONSTITUTION: A ceiling type air conditioner includes a bell mouse(58) for guiding air flow for reducing generation of vortex flow at a suction hole between the bell mouse and a shroud(57), so that the air flow amount is increased and the whole efficiency of the air conditioner is improved while reducing the noise due to the vortex flow, wherein the end part of the bell mouth is folded in the shape of sine function curve facing an air flow direction of the suction hole.
