For this reason, the suction airflow A1 and the blowing airflow B2 can be made to circulate along the ceiling surface, and it is possible to suppress the occurrence of a short circuit between the blowing airflow B2 and the suction airflow A1. Therefore, the air conditioning efficiency can be improved.
- the air conditioner is described as an example of the air conditioner.
- a filter may be used instead of the heat exchanger 205 to apply the air conditioner.
- a filtration filter a dust collection filter, a deodorizing filter, a disinfection filter etc. can be used, for example.
- the simultaneous supply / exhaust ventilation fan according to the present invention allows the suction airflow and the blowout airflow to flow in the same direction along the ceiling surface, and the blowout airflow blown into the room and the air drawn from the room This method is suitable for a method of suppressing the occurrence of a short circuit with the suctioned airflow.
