Abstract

A ventilation apparatus includes a housing having a front cover having an indoor air inlet and an air discharge opening, a rear cover having an outdoor air inlet and an indoor air outlet, and a side cover configured to connect edges of the front cover and the rear cover; a separation wall dividing the housing into a ventilation portion and an air conditioning portion; a total heat exchanger located in the ventilation portion; a supply-side mullion located adjacent to a first side of the side cover to define an outdoor air supply passage between the supply-side mullion and the first side of the side cover; a discharge-side mullion located adjacent to a second side of the side cover in the air conditioning portion to define an indoor air discharge passage; and an evaporator located between the supply-side mullion and the discharge-side mullion in the air conditioning portion.
