The present invention relates to a total heat exchanger for ventilating indoor air, and more particularly, a total heat exchange unit provided with a heat exchange element, a filter unit provided under the total heat exchange unit, and a first unit provided on the side and lower surfaces of the filter unit, respectively. ,2 air flow chamber part, the filter part is composed of a filter unit and a lower chamber and an upper chamber on the upper and lower sides of the filter unit, and the total heat exchange part has spaces above and below the front and rear surfaces, and heat exchange elements are arranged between the front and rear spaces for heat exchange. It minimizes the heat exchange width of the heat exchange element in the same space by minimizing the width of the heat exchanger by minimizing the width of the heat exchanger in the same space by minimizing the width of the heat exchanger by minimizing the heat exchange width of the heat exchange element in the same space by providing a bypass pipe that directly supplies the outside air flowing through the filter unit to the air supply space where the air supply fan is provided. It relates to a total heat exchanger including a large-capacity filter that further improves ventilation efficiency while reducing noise with a small fan capacity by maintaining the performance of the supply and exhaust fan.

In general, air in an enclosed activity space provided inside a building increases or pollutes the content of carbon dioxide over time due to the respiration or activity of the occupant, causing many harmful effects on the internal activity or health of the occupant.

Therefore, when a person stays in a narrow space such as an enclosed space such as an office, the contaminated air in the internal space must be replaced with fresh outdoor air from time to time for ventilation. At this time, it is a ventilation device that is commonly used.

Most of the conventionally known ventilation devices employ a method of forcibly discharging only indoor air to the outside using a single blower fan. However, when only indoor air is forcibly discharged using a single blower fan, indoor cold air or heat is discharged to the outside without filtration, and outdoor air flows in without heat exchange through doors or windows. The cost of cooling has become unnecessarily high.

In addition, as sudden cold air and heat flow from the outside to the inside, people inside the room feel uncomfortable due to the sudden temperature change of the indoor air, especially when only indoor air is discharged to the outside when the window or door frame is closed. In addition to the fact that the inflow of fresh air from outside may be blocked, an oxygen deficiency phenomenon may occur, as well as the problem of not maintaining a comfortable indoor environment even though the ventilation system is provided because humidity control of the indoor air is not performed at all. .

In order to solve such a conventional problem, a total heat exchange type ventilation device has been proposed that exchanges heat with the discharged indoor air first when the indoor air is discharged to the outside and then supplies the outdoor air to the room.

In the process of discharging indoor air to the outside and at the same time supplying outdoor air to the room, the above total heat exchange ventilation system exchanges heat between the indoor air discharged to the outside and the outdoor air flowing into the room. , Increase the temperature of the outdoor air flowing into the room to bring it closer to the indoor air to supply air.

Accordingly, even if the indoor air is introduced and ventilated, the change in the indoor temperature is reduced, thereby minimizing an increase in the load required for cooling or heating.

A general overview of the configuration of a total heat exchange ventilation system is that an air supply duct that guides outdoor air to the room is provided inside a hollow body, and an exhaust duct that crosses the air supply duct at a predetermined position and guides the indoor air to the outside. Is equipped. In addition, a total heat exchanger for exchanging heat between the supplied outdoor air and the exhausted indoor air is provided at a point where the supply duct and the exhaust duct intersect. At this time, the air supply duct and the exhaust duct are not interfered with each other by the partition wall partitioning the interior of the body up and down.

As a related art, Korean Patent No. 10-1272674 and Korean Patent Publication No. 10-2008-0024379 have improved heat exchange efficiency by uniforming the flow of indoor and outdoor air.

However, since the conventional total heat exchanger is installed and operated on the ceiling, there is a problem that it is very difficult and difficult to exchange and install a filter (pre-filter) provided in the heat exchange element due to a narrow space.

In addition, since the filter provided in the conventional total heat exchanger is installed in the external air supply part of the heat exchange element, there is a limitation in that the size (capacity) of the filter cannot be increased due to the limitation of the installation space.

In order to solve this problem, the present applicant applied for and registered patent No. 10-2079211. In order to improve heat exchange performance, the total heat exchanger may increase (widen) the heat exchange width, which is transferred by intersecting internal or external air from the heat exchange element, but in this case, the size of the equipment is increased because the performance of the supply/exhaust fan corresponding thereto must be increased. There are problems that cause economic and environmental problems such as increased space constraints, electricity consumption and noise as well.
