Thermal energy contained in the indoor air is recovered indoors.

However, if heat exchange ventilation is to be performed in two rooms with the above configuration, a heat exchange type ventilation system must be installed in each room. Since the exhaust vanes, air supply vanes, motor, etc. are built into the main body, the dimensions of the main body are large and the weight is heavy, making installation work extremely difficult.
Another drawback was that the ducts could not be connected after the ceiling panels were pasted, so installation work could not be carried out. Furthermore, since a large ceiling opening is required for attaching the main body, in the case of a rod edge ceiling, the rod edge must be cut, resulting in problems such as poor appearance. Furthermore, when cleaning the heat exchange element, the louver is large in size, making it troublesome to remove, and the heat exchange element is also heavy, so there is a high risk of it falling. Furthermore, when replacing the main body, it is necessary to remove the ceiling plate, and when replacing the motor, etc., it is necessary to work near the ceiling, making maintenance and inspection difficult. Additionally, since the motor and blades are located in the main unit, noise during operation easily enters the room through the louver, increasing indoor noise. Although installation work and maintenance inspection for wall-embedded heat exchange type ventilation equipment is easy,
Since it must be installed on a wall facing outdoors, the installation location is limited, and the louver protrudes from the wall, resulting in an unsatisfactory appearance.

OBJECT OF THE INVENTION The present invention solves these conventional drawbacks and facilitates the installation and maintenance inspection of a heat exchange type ventilation system when performing heat exchange ventilation for two rooms, as well as improving the appearance. The present invention provides a heat exchange type ventilation device that reduces noise.
