VENTILATION SYSTEM FOR BOTH NATURAL VENTILATING AND HEAT EXCHANGE

摘要

An automatic ventilation system for natural ventilation and heat exchange is provided to save energy by selectively performing natural ventilation and ventilation using a heat exchange unit through selectively operating a fan. An automatic ventilation system for natural ventilation and heat exchange comprises a natural ventilator, a heat exchanger, and a controller(120). The natural ventilator adheres to one side of a window. The natural ventilator is formed with the joint of inner and outer cases. In the inner/outer cases, indoor/outdoor air guide parts(30,40) of a grille shape are formed respectively at the middle portion. The indoor/outdoor air guide parts are opened and closed by each motor. The heat exchanger is made of indoor/outdoor air supply ports(91,93), indoor/outdoor air ducts(81,82), a heat exchange unit(50), indoor/outdoor exhaust ports(90,92). Each duct is connected to the heat exchange unit. The indoor air supply port and the outdoor exhaust port are installed at the bottom of the inner/outer cases. A fan is built in each exhaust port and air supply port. The controller is installed between the indoor exhaust port and the indoor air guide part and controls each fan.
