PURPOSE : A complex heat exchange/ventilation device is provided to enable the purified air to be re-supplied to an indoor space after the contaminated indoor-air is purified using an ion generator, which is installed in an exhaust space. CONSTITUTION : A complex heat exchange/ventilation device comprises a case(10), a heat exchanger, a filter(50), an intake fan(20), and an exhaust fan(30). The case comprises an intake hole(141), an exhaust hole(142), a supply hole(162), a discharge hole(161), an intake duct, an exhaust duct, an intake space(14), and an exhaust space(16). A re-supplying space(15) is formed in a part of the intake space of the case. The re-supplying space comprises a re-supplying hole(153) and is connected to the discharge part(22) of the exhaust fan. The re-supplying space is communicated with the exhaust pipe. A blocking unit(154), which selectively blocks one of the exhaust hole and the re-supplying hole as needed, is formed in the re-supplying space. A small ion generator(60) is installed in the exhaust space of the case. |
