AIR FEED/EXHAUST UNIT AND VENTILATION SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an air feed/exhaust unit which simplifies a system by formed into a small size and a lightweight, reduces the manhour and the cost for the construction, prevents intrusion of pollen, etc., by the air pressure of a living space turned into the negative pressure, and efficiently ventilates, and also to provide a ventilation system using the same.;SOLUTION: This air feed/exhaust unit 1 is provided with an air feed/exhaust part disposed on a ceiling part in a room, and an adjusting means 4 adjusting the exhaust air quantity from the air feed/exhaust part. The air feed/exhaust part is provided with an air feed means 2 leading the outside air to the room inside and a natural exhaust means 3 connected to the adjusting means 4 and naturally exhausting the indoor air to the outside. This ventilation system is provided with the air feed/exhaust unit 1, a forced exhaust means 28 provided in a different place from the air feed/exhaust unit 1, and an auxiliary air feed means 2 feeding the same air capacity to the exhaust air capacity of the forced exhaust means 28.;COPYRIGHT: (C)2004,JPO
