APPARATUS FOR HEAT EXCHANGE OF VENTILATOR

摘要

PURPOSE: An apparatus for heat exchange of a ventilator is provided to prevent rapid fluctuation of indoor temperature during ventilation by reducing heat loss of indoor air. CONSTITUTION: An apparatus comprises a main body(20) formed as a box with a storage space formed therein, and mounted on a window frame; a heat exchange unit(30) formed to be a cylinder, mounted on a middle part of the main body to rotate, and formed with aluminum foam to allow air to pass in vertical direction; a discharge channel(23) guiding indoor air to pass one side of the heat exchange unit and to be discharged to the outside; an inflow channel(24) guiding outdoor air to pass the other side of the heat exchange unit and to be introduced into a room; an upper fan(51) mounted on an upper side of the heat exchange unit to discharge indoor air to the outside; and a lower fan(52) mounted on a lower side of the heat exchange unit to introduce outside air into the room. The upper fan rotates faster than the lower fan to rotate the heat exchange unit.
