PURPOSE: An energy-saving hybrid ventilator using natural ventilation is provided to maintain the quality of indoor air using both natural ventilation and compulsory air supply. CONSTITUTION: An energy-saving hybrid ventilator using natural ventilation comprises a body(120), a motor damper(130), an electrical heater(160), and an air supply fan(121). The body comprises an indoor air supply unit(123) and a plate(124) for holding an outdoor air supply unit. The motor damper comprises a damper(132). The damper selectively opens/closes the outdoor air supply unit to control the amount of outdoor air to be sucked. The electrical heater prevents dew condensation maintaining the inner temperature of the body and an appropriately dry state. The air supply fan sends outdoor air to indoor space with strong sucking pressure.
