Problems solved by technology

[0006] First, since the ceiling is designed to have a limited thickness, the height of the total heat exchanger installed inside the ceiling is limited
For this reason, the height of the heat exchange element built into the total heat exchanger for heat exchange between indoor air and outdoor air is limited
As a result, the heat exchange area of ​​the heat exchange element is reduced, resulting in a relative decrease in the total heat exchange efficiency of the total heat exchanger
[0007] Second, the air flow rate through the heat exchange element is too high to allow the heat exchange element to effectively perform the desired heat exchange operation
As a result, the efficiency of the total heat exchanger is reduced
[0008] Third, there is a problem that flow resistance increases due to greatly changing the flow directions of indoor air and outdoor air passing through the heat exchanging element

Abstract

A total heat exchanger having a structure capable of achieving an enhancement in total heat efficiency, and a ventilation system using the total heat exchanger are disclosed. The total heat exchanger includes an air supply duct for guiding outdoor air to an indoor space, an air discharge duct for guiding indoor air to the outdoors, an air supply fan arranged at one side of the air supply duct, the air supply fan sucking the outdoor air, and supplying the sucked air to the indoor space, an air discharge fan arranged at one side of the air discharge duct, the air discharge fan sucking the indoor air, and discharging the sucked air to the outdoors, and a heat exchanging element arranged at a region where the indoor air and the outdoor air cross each other, the heat exchanging element heat-exchanging the indoor air with the outdoor air. The heat exchanging element has a shape causing the indoor air and the outdoor air to flow through the heat exchanging element while forming an acute angle with respect to each other.

Description

[0001] This application claims priority from Korean Patent Application No. P2005-46326 filed on May 31, 2005, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a total heat exchanger and a ventilation system using the total heat exchanger, more particularly, to a total heat exchanger with an improved structure so as to have an increased heat exchange area, thereby improving the efficiency of the total heat exchanger, and the use of The ventilation system of the full heat exchanger. Background technique [0003] Generally, air in a closed space such as an indoor space is gradually polluted as time goes by due to repeated breathing of a living body in the indoor space. Therefore, it is necessary to frequently replace polluted air in indoor spaces with fresh outdoor air. For this purpose, ventilation systems using total heat exchangers are usually used. [0004] Specifically, various ventilation system...
