<p>The present invention relates to a heat exchanger equipped with a door. The present invention comprises: a body formed with an internal outlet and an external inlet on one side thereof and an internal inlet and an external outlet on the other side thereof, including a plurality of diaphragms formed and connected on the inner surface, and having an absorbing flow path guiding outdoor air to the inside and a discharge flow path guiding indoor air to the outside formed by crossing each other; an inhalation fan equipped inside the body and arranged to be connected to the external outlet, blowing the outdoor air to the inside; an exhaust fan installed in a side of the absorbing fan and arranged to be connected to the internal outlet, blowing the indoor air to the outside; a heat exchanger element installed close to an end part of the diaphragms for the outdoor air and the indoor air, absorbed inside the body and emitted by the inhalation and exhaust fans, to exchange heat with each other; a door part installed on the bottom of the body and located in the lower part of the exhaust fan to discharge polluted air into the lower space wherein the heat exchanger is installed. As the door part capable of opening and closing the door is installed on the bottom of the heat exchanger, the indoor air can be maintained clean since the polluted air is discharged into the lower space, where the heat exchanger is installed, through the internal outlet after the exhaust fan is operated.</p> |
