VENTILATION APPARATUS

摘要

A ventilation apparatus is provided. The ventilation apparatus may include a base, frames positioned on the base, a rear panel positioned behind the frames and having an interior air discharge port and exterior air suction port formed therein, a top cover positioned on top of the frame and having exterior air discharge port formed therein, and a front panel positioned in front of the frames and having an interior air discharge port formed therein. Heat exchangers disposed in the frames may include interior and exterior air passages. An exhaust fan and air supply fans provide for air flow through the apparatus, guide by the frames. Use of the frames to guide air flow simplify structures and may enhance efficiency by simplifying the passages of the exterior and interior air through the apparatus.
