As shown in FIG. 9, the second switching valve B opens the outdoor air supply port 37 and the indoor air. The discharge port 36 is closed. Therefore, when the supply / exhaust fan 23 is operated (ON), outdoor air is sucked from the outdoor air supply pipe 26, passes through the outdoor air suction path Q and the indoor supply path S, and enters the duct 53 from the air supply port 37. Then, it flows through the cover 51 of the ultraviolet lamp device 50 and flows into the air conditioner 1 from the outlet 51A while being sterilized or sterilized by the ultraviolet lamp 52. The outdoor air that has flowed out into the air conditioner 1 is circulated into the house room by the blower 4 in the air conditioner 1. At the same time, the air in the house room is discharged to the outside by the operation (ON) of the exhaust fan 24.

  As described above, in the exhaust mode, the indoor exhaust can be quickly performed by the operation (ON) of the supply / exhaust fan 23 and the exhaust dedicated fan 24, which is effective when the indoor air is contaminated.

In the air supply / exhaust mode, air supply and exhaust are simultaneously performed by the operation (ON) of the air supply / exhaust fan 23 and the exhaust exclusive fan 24, so that an indoor air purification promoting effect can be exhibited. Since these controls can be achieved by the passage switching by the first switching valve A and the second switching valve B and the operation (ON) of the supply / exhaust fan 23 and the exhaust fan 24, the control is easy and accurate.

  The outdoor air supply pipe 26 and the outdoor exhaust pipe 27 are not two pipes as shown in the figure, but a single pipe (pipe) communicating with the outdoor air suction port 33 and the indoor air discharge port 36. If the air supply and exhaust are combined, the pipe extending from the air conditioner 1 to the outside is connected to this one pipe (pipe) and the discharge port 28B that forms the exhaust passage of the exhaust exclusive part 22. Two pipes are used. Furthermore, if the pipe connected to the discharge port 28B is omitted and the pipe connected to the discharge port 28B is also used as a single pipe (pipe), the pipe extending from the air conditioner 1 to the outdoor side is It is possible to have only one pipe (pipe).
