VENTILATION SYSTEM IMPROVING THERMAL EFFICIENCY

摘要

The present invention relates to a ventilation system which improves thermal efficiency. The ventilation system according to the present invention includes: a main body frame which has an exhaust channel which connects an indoor space with an outdoor space and an intake channel which connects the indoor space with the outdoor space and is independent from the exhaust channel; a heat exchange unit which is installed in the main body frame so that a heat exchange is generated between the exhaust channel and the intake channel; an exhaust pump which makes indoor air flow to the outside through the exhaust channel; and an intake pump which makes outdoor air flow into the inside through the intake channel. According to the forementioned, thermal efficiency is improved by thermally exchanging warm indoor air with cold air flowing into the indoor space when the warm indoor air flows out and thermally exchanging cold outdoor air with warm air flowing into the indoor space when the cold indoor air flows out by thermally exchanging the outdoor air flowing in with the indoor air flowing out in a thermal exchange unit.
