－工作情况－-working condition-
当该空调装置的室外机组10运转时,压缩机构50就工作,制冷剂在形成于该室外机组10和未图示出的室内机组之间的制冷剂回路内循环而进行制冷循环。在室外机组10的机壳20内,室外风扇40旋转,由形成在机壳20的下半部分的吸气口25从四面吸入机壳20内的室外空气通过室外热交换器30。通过室外热交换器30的室外空气与在室外热交换器30中流动的制冷剂进行热交换,在进行制热运转时，该室外空气在作为蒸发器的室外热交换器30中被制冷剂夺走其热量而被冷却，在进行制冷运转时，该室外空气在作为冷凝器的室外热交换器30中从制冷剂夺取热量而被加热。然后,室外空气进一步通过室外风扇40,流动方向变成朝向上方,从出风口26朝着室外吹出。When the outdoor unit 10 of the air conditioner is in operation, the compression mechanism 50 operates, and refrigerant circulates in a refrigerant circuit formed between the outdoor unit 10 and an unillustrated indoor unit to perform a refrigeration cycle. In the casing 20 of the outdoor unit 10 , the outdoor fan 40 rotates, and the outdoor air sucked into the casing 20 from four sides by the suction port 25 formed in the lower half of the casing 20 passes through the outdoor heat exchanger 30 . The outdoor air passing through the outdoor heat exchanger 30 exchanges heat with the refrigerant flowing in the outdoor heat exchanger 30, and the outdoor air is robbed by the refrigerant in the outdoor heat exchanger 30 serving as an evaporator during heating operation. The outdoor air is cooled by dissipating its heat, and the outdoor air is heated by depriving heat from the refrigerant in the outdoor heat exchanger 30 serving as a condenser during cooling operation. Then, the outdoor air further passes through the outdoor fan 40, the flow direction becomes upward, and is blown out from the air outlet 26 toward the outside.
－冷凝水的排出工作－- Drainage of condensed water -

After the condensed water of the outdoor heat exchanger 30 drips downward, it is caught by the drain passage 71 formed in the bottom frame 22 . Part of the condensed water flows into the drain passage 71 through the drain hole 74 on the installation platform 73 where the outdoor heat exchanger 30 is installed. At this time, since the heater 75 is energized, the condensed water in the drain passage 71 is heated, thereby preventing the condensed water from freezing. Condensed water in the drain passage 71 is drained to the outside of the cabinet 20 through the drain hole 72 formed in the drain passage 71 .
此外，在本实施方式中，是在进行制热运转时对加热器75通电。但是，也可以是在其它运转模式中，当室外空气温度低于规定温度时对加热器75通电，还可以是在进行任一种运转时都对加热器75通电。In addition, in the present embodiment, the heater 75 is energized during the air-warming operation.
