摘要： A window-mounted air conditioner has indoor and outdoor heat exchangers associated with respective first and second fans, and a duct for forming an air passage. One part of the air passage has a larger cross sectional area than another part thereof disposed upstream of the one part. A guide blade is positioned in the one part to divide the one part into sections so that the velocity and pressure of air flowing through the one part is substantially the same as the velocity and pressure of air flowing through the other part.
