摘要： PROBLEM TO BE SOLVED: To avoid that air containing much moisture in a bathroom flows into a separate room, by a system wherein the air in the bathroom and air in the separate room are exhausted outdoors simultaneously by a forced exhaust means, from an exhaust passage for the bathroom and an exhaust passage for the separate room respectively, and thereby both of the room are ventilated. SOLUTION: A circulation passage for a bathroom equipped with a heat exchanger 4 is so formed that air in the bathroom A sucked form a suction part 2 by an operation of a circulation fan 1 for the bathroom is let out into the bathroom A from an outlet part 3. A circulation passage for a separate room equipped with a heat exchanger 10 is so formed that air in a dressing room B sucked from a suction part 6 of the room B and a duct 7 by an operation of a circulation fan 5 for the dressing room is let out into the room B from a discharge duct 8 and an outlet part 9. The air in the bathroom A and that in the dressing room B are exhausted outside simultaneously through a ventilation duct 11 by a ventilation fan 12. A shutter member 13 prevents the moisture in the bathroom A from flowing out onto the dressing room B side and it is opened and closed by a force of draft accompanying a ventilating operation of the ventilation fan 12.
