The present invention is an air conditioner with tangential blowers having an arrangement for cooling the blower's driving motor. The motor is attached exteriorly from the air moving chamber and the sidewall through which the motor is attached to the blower includes an axially located aperture. Blade extensions of the blower near the aperture induce an air flow through the aperture, and the induced air flow passes through the motor to carry away undesired heat. A seal can be formed between the motor and sidewall so that the induced air flow must pass through the motor.

Method and apparatus for cooling motors of cross flow blowers

The present invention is an air conditioning unit with indoor and outdoor heat exchanger coils and a pair of dual tangential flow blowers. Air flow is induced through the coils at a uniform rate and exhausted through an outlet. A single scroll dividing wall divides the housing of the air conditioner into indoor and outdoor compartments. The air-conditioning unit has a relatively small depth because the blowers are positioned in vertical alignment. The air intake arrangement on the indoor side is an intended, recessed portion of the cabinet. A removable louvered cover is positioned in an aperture located in the indented, recessed portion for allowing access to the filter.
