  • Patent number: 7865074
    Abstract: Disclosed herein is a rotary-type heat recovery ventilation apparatus, which is constructed to perform heat exchange between inlet air and exhaust air. The apparatus includes a main body having an intake duct and a discharge duct therein, a plurality of electric heating plates passing through a space in the intake duct and the discharge duct of the main body to transfer heat, and rotating about a main shaft, with a plurality of pores being formed on each of the electric heating plates, a pair of blowing fans mounted to a surface of the intake duct and a surface of the discharge duct, thus blowing and exhausting air, and a motor to rotate the main shaft. The ventilation apparatus transfers heat, recovered from air exhausted from a room during ventilation, to inlet air, and filters various impurities from the passing air, thus circulating fresh air without the energy loss.
