Abstract
An outdoor unit of a separate type air conditioner has suction ports and a blow-out port which can be disposed freely on the same side of the unit. Also, an outdoor unit of a one-side suction and exhaust type is excellent in static pressure characteristic, sufficient in air flow rate using only one blower, and is easy to install. Suction ports (8) are disposed at both sides in the front side of an outdoor unit main body (outer case 7), and a blow-out port (6a) is disposed in the center of the front side. A heat exchanger (3), an orifice (5), and one centripetal fan (1) are sequentially disposed behind the blow-out port (6a), thereby forming a draft circuit for sucking air from the suction ports (8) at the outer circumference of blades (1a) of the centripetal fan (1). The air is blown out ahead of the blades (1a) through the orifice (5) and heat exchanger (3). Therefore, since suction space is not required, the outdoor unit can be installed close to a wall. In addition, by the use of the centripetal fan (1), a sufficient air flow rate is obtained with only one blower, and the size of the outdoor unit for producing a same capacity may be kept to a minimum.
