    • 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.
    • 空调机采用包括压缩机1,室外热交换器5,室内热交换器9,膨胀阀7以及由密封在制冷循环中的高沸点冷却剂组成的非共沸冷却剂混合物的制冷循环。 室外热交换器5设置有第一鼓风机15和第二鼓风机17.速度控制器18驱动并控制第一和第二鼓风机15和17.速度控制器18实现第一模式以减少部分的空气量 位于冷却剂流的上游侧的室外热交换器的空气量比空气量低的部分位于冷却剂流动下游侧的室外热交换器,第二模式将空气量增加到 室外热交换器的上游侧比室外热交换器的下游侧的空气量大。
