アン本体である。 Further, the outdoor heat exchanger 13 is formed from a group of copper tubes 16 and aluminum fins 17, and the surface of the aluminum fins 17 is coated with a hydrophilic paint (not shown). Reference numeral 18 denotes an outdoor air outlet that forms a part of the outdoor ventilation circuit 19, 20 a cross flow fan air guider that forms the outdoor ventilation circuit 19, and 21 a stabilizer that forms the outdoor ventilation circuit 19. 22 is a cross flow fan body disposed within the ventilation circuit 19.

図ることができる。 However, since the fins 17 are coated with a hydrophilic paint, the dew falls immediately downward on the fins 17, so that the same effect as the conventional one can be obtained. On the other hand, the air that exits the heat exchanger 13 then passes through the heat exchanger 14, but since this air has low absolute humidity, it is difficult to condense on the surface of the fins 23 of the heat exchanger 14. 23
Even if the heat exchanger is not coated with a hydrophilic paint, the same effects as conventional ones can be obtained, and the cost of the outdoor heat exchanger can be reduced. Furthermore, by appropriately adjusting the fin pitches of the heat exchangers 13 and 14, it is possible to further improve the antifreeze performance and the heat absorption performance at low temperatures.
