<p><P>PROBLEM TO BE SOLVED: To provide a heat recovery device making a heat recovery rate high by enhancing humidity exchange efficiency. <P>SOLUTION: The heat recovery device 1 includes an air supply line 1a stored in a casing 1c to suck outside air from an outside air suction port 11 by an air supply blower 4 and to supply air indoors from an air supply port 12 through an air supply passage 2a of a total enthalpy heat exchanger 2, and an exhaust line 1b sucking indoor return air from a return air port 13 by an exhaust blower 3 and exhausting the air from an exhaust port 14 through an exhaust passage 2b of the total enthalpy heat exchanger 2. The heat recovery device also includes a cooler 5 installed in the exhaust line 1b between the return air port 13 and the total enthalpy heat exchanger 2 and cooling the return air to raise the relative humidity of the return air. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
