Ventilator

摘要

PURPOSE: A ventilation system is provided to prevent molds caused by dew condensation by preventing dew from condensing on a window in the winter. CONSTITUTION: A ventilation system(100) comprises a main body(110), a blade, a gasket, filter bodies(131), and phase change materials. The main body has an outdoor air inlet. The blade is rotatably installed on the outdoor air inlet and opens and closes the outdoor air inlet. The gasket is formed on the main body and prevents air from flowing into the outdoor air inlet when the blade closes the outdoor air inlet. The filter bodies are installed in an outdoor vent and an indoor vent(112) of the main body and filter foreign materials from the air flowing though the outdoor air inlet. The phase change materials are formed on one or more of the blade, the gasket, and the filter bodies and prevent dew condensation.
