    • A dew preventing mechanism prevents the formation of dew on the grilles of an air discharge port of a room air conditioner by activating a heater which heats the grilles in response to the sensing of certain dew-forming conditions. The air conditioner includes thermistors for sensing the temperatures of incoming room air and outgoing cooled air, respectively, and a hygrometer for sensing the humidity of incoming room air. Signals proportional to those temperatures and humidity are sent to a control device which calculates the dew point of the incoming room air and compares the humidity of the incoming air with a reference humidity. When the outgoing air temperature is less than the dew point, and/or the incoming air humidity exceeds the reference humidity, the heater is actuated.
    • 防露机构通过启动加热器来防止室内空调的排气口的格栅上的露水,该加热器响应于某些露水条件的检测而加热格栅。 空调包括分别用于感测进入的室内空气和出风冷空气的温度的热敏电阻和用于感测进入的室内空气湿度的湿度计。 与这些温度和湿度成比例的信号被发送到控制装置,该控制装置计算进入的室内空气的露点,并将进入的空气的湿度与参考湿度进行比较。 当出风温度小于露点和/或进气空气湿度超过参考湿度时,加热器被致动。
