摘要： A blowing device having an air suction guide with an improved structure to reduce blowing operational noise, and an air conditioning apparatus having the blowing device. The blowing device includes a blowing fan, a fan casing placed to cover the blowing fan and having a suction port, and a suction guide provided in the suction port of the fan casing to guide inlet air to the blowing fan. The suction guide includes a flow guide part extending forward from an edge of the suction port of the fan casing by a predetermined length. Due to the flow guide part of the blowing device, the inlet air flows through the suction port at a constant flowing speed and in a state of laminar flow. Therefore, the blowing device reduces a variation in a pressure applied onto blades of the blowing fan by the inlet air, and reduces operational noise thereof.

摘要： A turbo fan including backward-inclined blades that are inclined in a direction opposite to a rotating direction of a rotating plate. A positive pressure surface of each blade, facing the rotating direction of the rotating plate, takes the form of a flat surface, and a negative pressure surface of the blade, opposite to the rotating direction of the rotating plate, takes the form of a convexly-curved surface. A radius of curvature defined by the convexly-curved negative pressure surface is within a range of 2.5˜4 times of a radius of the turbo fan. The turbo fan can reduce noise and consumption of power together, and consequently, an air conditioner having the turbo fan can achieve an improvement in performance.
