2. Description of the Related Art From the viewpoint of energy saving, so-called "highly airtight and highly insulated houses" are widely used especially in cold regions from the viewpoint of energy saving. In recent years, there is a trend to adopt highly airtight and highly insulated houses even in warm areas due to energy.

In the exhaust system, an air supply port is provided in each room,
Dirty air is intensively exhausted from a return air port provided in a corridor, a washroom, or the like, through a duct connected to a unit with a built-in fan. This system is simple and inexpensive, but it is hot in summer and cold in winter because the outside air enters through the ventilation holes of each room. Further, since there is no heat exchange between the incoming outside air and the air discharged to the outside and no heat recovery, heat loss occurs due to ventilation.

However, in the unit having the above-mentioned structure, the air-conditioning and ventilation element 2 is once supplied in order to supply the outdoor air to the room at the same temperature as the room air so as not to disturb the indoor thermal environment. After performing the heat exchange in step (2), cooling or heating is performed twice in the use side heat exchanger, and the number of parts is large. Further, when the indoor air is discharged outside, the heat is exchanged by the air conditioning and ventilation element 2 and then passed through the heat source side heat exchanger, so that the heat radiation effect is reduced in the case of heat radiation and the heat absorption effect is reduced in the case of heat absorption. Let me. Furthermore, since the air conditioning ventilation element 2 and the heat exchanger requiring condensed water treatment are used in combination, the air supply path and the exhaust path must be arranged on substantially the same plane. Therefore, for example, a configuration in which the exhaust path is located at the upper part and the supply path is located at the lower part cannot be taken, and there is a problem that the degree of freedom in arranging parts is small and the main body becomes large.
