<p>PURPOSE: A ventilation system for improving space efficiency and minimizing the size of a necessary device is provided to reduce a cost of product installation and space efficiency. CONSTITUTION: A ventilation system for improving space efficiency and minimizing the size of a necessary device determines a driving mode(S100). The air ventilating operation through the heat exchange between the indoor air and the outside air is performed. The operation mode comprises an air ventilating operation mode, a cooling/heating drive mode, and a co-operation mode. The air ventilating operation mode exchanges indoor air and outdoor air. The cooling/heating drive mode flows outdoor air into inside of the system.</p> |
