To provide a heat exchange ventilation device which never spoils ventilation efficiency even in defrosting operation.SOLUTION: A heat exchanger 1 and opening/closing parts 3, 4 which partition off an outdoor space and an indoor space and adjust flow passage are provided such that air flows in mutually opposite directions in a first ventilation path 1a and a second ventilation path 1b in a heat exchanger 1 in normal operation and in defrost operation without changing the blowing direction of an air feed and exhaust fan. The opening/closing part 3 on the outdoor side connects an outside air intake 21 to one end of the first ventilation path 1a (or second ventilation path 1b) and also connects an exhaust port 22 to one end of the second ventilation path 1b (or first ventilation path 1a), and according to a flow of an air current, the indoor-side opening/closing part 4 connects an air intake 23 to the other end of the first ventilation path 1a (or second ventilation path 1b) and also connects an exhaust port 24 to the other end of the second ventilation path 1b (or first ventilation path 1a).SELECTED DRAWING: Figure 3
【課題】デフロスト運転時においても換気効率を損なわない熱交換換気装置を得る。【解決手段】給気・排気ファンの送風方向は変更することなく、通常運転時の熱交換器1内の第一の換気路1aと第二の換気路1bの空気の流れが、デフロスト運転時に逆となるように、熱交換器1と室外空間、室内空間を仕切り、流路の調整を行う開閉部3、4を設ける。室外側の開閉部3は、外気吸入口21と第一の換気路1a(または第二の換気路1b)の一端を接続するとともに、排気口22と第二の換気路1b(または第一の換気路1a)の一端を接続し、その気流の流れに合わせて、室内側の開閉部4は、給気口23と第一の換気路1a(または第二の換気路1b)の他端を接続するとともに、排気吸入口24と第二の換気路1b(または第一の換気路1a)の他端を接続するよう構成する。【選択図】図3
