Abstract
Abstract An air ventilating unit provided with a rotary heat exchanger assembly communicating between an incoming air passage and an outgoing air passage for heat recovery in air conditioning. The ventilating unit is adopted to enable direct deposition on the upper wall of an air conditioner. When the ventilating unit is mounted on the air conditioning unit, the outside air (fresh air) outlet formed in the front wall of the ventilating unit is positioned closely adjacent to the air outlet of the air conditioning unit. Room air inlets are formed on both side walls of the ventilating unit.
