In addition, by dividing the lower surface panel 33 into two, it is not necessary to handle the entire lower surface panel 33 integrally, and the transport and manufacture of the lower surface panel 33 can be facilitated.

In addition, while the exhaust side vibration suppression filter 32 is arrange | positioned between the suction side opening part 21a of FIG. 6, and the panel suction port UI, the air supply side vibration suppression filter ( By arranging 16, even when only one side of the lower surface panel 33 is folded outward, the air supply side vibration elimination filter 16 and the exhaust side vibration elimination filter 32 can be easily taken out, and at the time of maintenance. Workability can be improved.

In addition, although the above-mentioned embodiment demonstrated the method of providing the heat exchanger 9 in the outer casing 1, the heat exchanger 9 may not be provided.

In addition, a damper device is provided which closes the bypass ventilation path and the exhaust ventilation path 14a which bypass the heat exchanger 9, and then opens the bypass ventilation path, thereby providing normal ventilation without accompanying heat exchange. You may make it possible.

Embodiment 6:

FIG. 11: is sectional drawing which shows schematic structure of Embodiment 6 of the air conditioning apparatus which concerns on this invention typically. In FIG. 11, an outer casing 201 is provided in the air conditioning apparatus, and a lower surface panel 203 is attached to the lower side of the outer casing 201 using the panel outer edge 202. In addition, the panel exterior frame 202 can be comprised in square cylinder shape. As the lower panel 203, for example, a makeup panel can be used.

And below the outer casing 201, the panel inlet port UI for sucking in the suction air flow A1 and the panel outlet port UO for taking out the blower airflow B2 are formed in the lower panel 203.

Here, the panel suction port UI and the panel blowout port UO can be formed in the panel 203 when they face each other. In this case, the panel inlet port UI and the panel outlet port UO are formed along the lower panel 203, and are drawn out from the direction of the suction airflow A1 sucked into the panel inlet port UI and from the panel outlet port UO. It is preferable to arrange | position so that the direction of the taken out airflow B2 may become the same.

In the outer casing 201, an air supply / exhaust ventilation path 206 is provided to secure a ventilation path between the panel suction port UI and the panel outlet port UO. In addition, a fan 204 and a heat exchanger 205 are provided on the supply / exhaust ventilation path 206. Here, the heat exchanger 205 can adjust the temperature of the intake airflow A1 suctioned from the panel intake port UI. In this heat exchanger 205, a compressor, a condenser, and an evaporator can be provided, for example. The fan 204 can suck the intake airflow A1 into the panel intake port UI, and can take out it from the panel outlet port UO as blowout airflow B2.

Then, when the intake airflow A1 of the room is sucked from the panel intake port UI, the intake airflow A1 is guided into the outer casing 201. The intake air stream A1 guided into the outer casing 201 is blown out into the room as the blowout air stream B2 from the panel blowout port UO after it is heat-exchanged by the heat exchanger 205.

Here, the panel inlet port UI and the panel outlet port UO are formed in the panel 203 when they face each other, so that the panel inlet port UI and the panel outlet port UO are formed from the direction of the intake airflow A1 sucked into the panel inlet port UI and from the panel outlet port UO. The direction of the blown out air stream B2 can be made the same. For this reason, since the intake airflow A1 and the blowout airflow B2 can flow so that it may circulate along a ceiling surface, it becomes possible to suppress that a short circuit arises between the takeout airflow B2 and the intake airflow A1, The air conditioning efficiency can be improved.

In addition, in Embodiment 6 of FIG. 11, although the air conditioner was mentioned as an example and demonstrated as an air conditioning apparatus, you may apply to an air cleaner by using a filtration filter instead of the heat exchanger 205. FIG. As the filtration filter, for example, a dust collecting filter, a deodorizing filter, an antibacterial filter and the like can be used.

As mentioned above, the simultaneous dispatch type ventilation fan which concerns on this invention can make a suction airflow and a blowout airflow flow in the same direction along a ceiling surface, and is short between the blown airflow blown in into the room and the intake airflow sucked from inside. It is suitable as a way to suppress the circuit from happening.
