PROBLEM TO BE SOLVED: To provide a heat exchange device that does not require frequent maintenance work even when installed in a poor outside environment.SOLUTION: The heat exchange device includes: an outdoor side main air course 24 that communicates an outdoor side air inlet 8 with an outdoor side air outlet 9 within a body case 14; an indoor side air course 26 that communicates an indoor side air inlet 19 with an indoor side air outlet 20; a heat exchanger 22 that is interposed in the outdoor side main air course 24 and the indoor side air course 26 and exchanges heat between air in the outdoor side main air course 24 and air in the indoor side air course 26; an outdoor side air blower 15 interposed in the outdoor side main air course 24; and an indoor side air blower 23 interposed in the indoor side air course 26. An electrostatic separation device 18 is installed between the outdoor side air inlet 8 in the outdoor side main air course 24 and the heat exchanger 22. Outside air sucked from the outdoor side air inlet 8 is separated into the two air courses by the electrostatic separation device 18. One of the air courses is connected to the heat exchanger 22, and the other air course is used for discharging outside air to the outdoor side. |
