    • An air conditioning system includes a compressor which is reversed in order to switch from a heating mode to a defrost mode, or in order to switch between heating and cooling modes. Prior to being reversed, the compressor is automatically reduced to a slower speed greater than zero for a predetermined time period to minimize damage and noise when reversal occurs. The compressor is reversed while at the slower speed when switching the system to a defrost mode. When switching between heating and cooling modes, the compressor speed is first reduced to the slower speed for the first predetermined time period and then to zero speed for a second predetermined time period, before the compressor is reversed.
    • 一个空调系统包括一个反转的压缩机,以便从加热模式切换到除霜模式,或者为了在加热和冷却模式之间切换。 在反转之前,压缩机在预定的时间周期内被自动地减小到大于零的较慢的速度,以在发生反转时最小化损坏和噪声。 当将系统切换到除霜模式时,压缩机反转速度较慢。 当在加热和冷却模式之间切换时,在压缩机反转之前,首先将压缩机速度降低到第一预定时间段的较慢速度,然后降低到第二预定时间段的零速度。
