Claim 0:
1. A conditioning ventilation system wherein
each of a plurality of rooms in a building is provided with an air-intake portion, an exhaust means A and an exhaust means B directing to outdoor having an opening/closing mechanism B capable of adjusting its opening/closing amount and capable of completely closing exhaust gas toward outdoor from the room,
a space other than a living room other than the plurality of rooms is provided with the air-intake portion and the exhaust means A,
an air blowing section which sends wind through a duct is connected to each of the air-intake portion,
the conditioning ventilation system is provided with a return air path which joins up from the plurality of exhaust means A and which returns to an air-conditioning compartment having at least one air conditioning section and the plurality of air blowing sections,
an outdoor air introduction path C having an opening/closing mechanism C capable of adjusting its opening/closing amount and capable of completely closing the same is connected to the return air path, and outdoor air is introduced,
return air from the plurality of rooms and spaces, the outdoor air and air which is air-conditioned by the air conditioning section are circulated in the building by the air blowing section, and, in this state,
volume of air which is discharged from the room to outdoor can be adjusted from 0 by the opening/closing mechanism B of the exhaust means B directing to outdoor of the room independently in the plurality of rooms when wind is sent from the air-intake portion of the room, and outdoor air introducing volume which is introduced into the building can be adjusted by the opening/closing mechanism C,
wherein the building is provided therein with an other room other than the plurality of rooms, the other room is provided with an air-intake portion having an exhaust means B directing to outdoor, an opening/closing mechanism B and a door in a state where the door is closed,
air from an opening formed by opening the door joins up with the outdoor air in midstream of the return air path,
volume of air which is discharged from the other room outdoor can be adjusted from 0 by the opening/closing mechanism B of the exhaust means B directing to outdoor of the other room when wind is sent from the air-intake portion of the other room, and existence or non-existence of return air from the other room can be switched by opening or closing the door.
