摘要： Stress to be imposed on a compressor in reverse cycle operation is reduced. A cycle controller 32a causes an outdoor heat exchanger 23 to function as a condenser and an indoor heat exchanger 25 to function as an evaporator when a reverse cycle executing condition is met, so that a refrigerant circulates in reverse of a heating cycle. A rotation speed controller 32b adjusts a rotation speed of a compressor 21 in a reverse cycle, depending on an index correlated with an amount of frost on the outdoor heat exchanger 23 at a start of the reverse cycle. The rotation speed controller 32b decreases the rotation speed of the compressor 21 in the reverse cycle as the index at the start of the reverse cycle indicates that the amount of the frost on the outdoor heat exchanger 23 is smaller.
摘要翻译：减少了逆向循环运行时对压缩机施加的压力。当循环控制器32a在逆循环执行条件得到满足时，循环控制器32a使室外热交换器23用作冷凝器和室内热交换器25以起到蒸发器的作用，使得制冷剂在加热循环的反向循环。转速控制器32b根据在逆循环开始时与室外热交换器23上的霜量相关的指标，以逆循环调整压缩机21的转速。当逆循环开始时的指标表示室外热交换器23上的霜量较小时，转速控制器32b在逆循环中减小压缩机21的转速。
