Abstract
An air conditioner employs a refrigerating cycle involving a compressor 1, an outdoor heat exchanger 5, an indoor heat exchanger 9, an expansion valve 7, and a non-azeotropic coolant mixture composed of high and low boiling coolants sealed in the refrigerating cycle. The outdoor heat exchanger 5 is provided with a first blower 15 and a second blower 17. A speed controller 18 drives and controls the first, and second blowers 15 and 17. The speed controller 18 achieves a first mode to decrease an air quantity to part of the outdoor heat exchanger located on the upstream side of a flow of the coolant smaller than an air quantity to part of the outdoor heat exchanger located on the downstream side of the flow of the coolant, and a second mode to increase the air quantity to the upstream side of the outdoor heat exchanger greater than the air quantity to the downstream side of the outdoor heat exchanger.
