Claim 4:
5. A conditioning ventilation system in which each of a plurality of rooms in a building is provided with an air-intake portion, an exhaust means D having an opening/closing mechanism D capable of adjusting its opening/closing amount and capable of completely closing itself, 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, and a door in a state where the door is closed,
a space other than a living room other than the plurality of rooms is provided with the air-intake portion and an exhaust means A,
an air blowing section which sends wing through a duct is connected to each of the air-intake portions,
the conditioning ventilation system is provided with a return air path which joins up with the plurality of exhaust means D and the 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 itself is connected to the return air path, and outdoor air is introduced,
an indoor air discharging path and an outdoor air introduction path D are connected to the return air path,
millstreams of the indoor air discharging path and the outdoor air introduction path D are provided with a heat-exchanging ventilating unit,
the heat-exchanging ventilating unit heat-exchanges between the outdoor air introduced from the outdoor air introduction path D and a portion of return air from at least one of the exhaust means A and the exhaust means D and, in this state, a portion of the return air is discharged to outdoor by the indoor air discharging path,
return air from at least one of the plurality of rooms and the space, 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, outdoor air introducing volume which is introduced into the building can be adjusted by the opening/closing mechanism C and the heat-exchanging ventilating unit, return air volume from the plurality of rooms can be adjusted by the opening/closing mechanism D of the exhaust means D independently in the plurality of rooms, wherein
total blast volume of the plurality of air blowing sections is set greater than air-conditioned air volume of the air conditioning section and the outdoor air introducing volume.
