Abstract
The present invention is an air conditioning unit with indoor and outdoor heat exchanger coils and a pair of dual tangential flow blowers. The blowers are driven by a single motor. The motor directly drives the first blower which is rotatably connected to the second blower. The rotational driving connection of the blowers is located on the opposite side of the motor and compressor.
