<p>Dust in the air is charged by an ionization unit (25), and the charged dust is adhered to an indoor heat exchanger (20). During the operation for cooling, dust is removed by condensed water generated in the indoor heat exchanger (20). On the other hand, during the operation for heating, condensed water generated in an outdoor heat exchanger (51) is supplied as washing water by a water supply unit (60) to the indoor heat exchanger (20) to remove dust.</p> |
