VENTILATION SYSTEM FOR ENERGY RECOVERY

摘要

Disclosed is a ventilation system for energy recovery, which formed of an inexpensive and easily-formable material so that overall weight of the system can be greatly reduced and an outer cover is kept relatively thin, which can be easily assembled without creating a gap between components to thereby reduce time and effort of assembly while ensuring convenient management, and which can solve problem caused by vibration or noise from a fan motor. The ventilation system includes: upper and lower molded bodies made of a non-metallic material such as polypropylene (PP), detachably coupled to each other, and formed with air through-holes and an air flow guide allowing intake and exhaust flow of air at opposite sides thereof when assembled; a heat exchanger mounted to a flexible mounting guide formed in the upper and lower molded bodies and performing heat exchange of air flowing through the upper and lower molded bodies; a fan motor supporter insertion-formed integrally with at least one of the upper and lower molded bodies; a plurality of fan motors accommodated in the fan motor accommodating part of the upper molded body, coupled to the fan motor supporter and driving air to flow into and out of the plural air through-holes; an outer cover closely coupled to lateral sides of the upper and lower molded bodies coupled to each other; a corner holding part coupled to a corner between the plurality of outer covers to hold the outer covers; and a cover and a base plate detachably coupled to upper and lower sides of the upper and lower molded bodies.
