VENTILATION SYSTEM FOR SUPPLYING AND EXHAUSTING CONSTANT AIR VOLUME INTO MULTI-ROOM

摘要

The present invention relates to a ventilation system capable of supplying and exhausting a plurality of indoor constant air volumes, and the present invention relates to a total heat exchanger for exchanging indoor air and outdoor air while exchanging indoor air to the outdoors and supplying outdoor air to the indoor; a plurality of unit ventilation devices respectively installed in a plurality of rooms, exhausting air in each room in a set amount on the total heat exchanger side and supplying outdoor air passing through the total heat exchanger in a set amount; a main air supply duct connected to the indoor air supply port of the total heat exchanger to guide the inflow of external air through the total heat exchanger into the room; branch air supply ducts that sequentially connect the main air supply duct and unit ventilation devices to guide outdoor air introduced through the main air supply duct to the unit ventilation devices in each room; A reverse return exhaust duct connecting the indoor exhaust port of the total heat exchanger and the plurality of unit ventilation devices, and guiding the air in the rooms to be exhausted to the total heat exchanger in a reverse order in which air is introduced into the branch supply ducts, is included. According to the present invention, not only uniformly ventilate multiple rooms of a building, but also purify each of the rooms.
