DEVICE FOR PREVENTING DEW CONDENSATION OF HEAT EXCHANGE TYPE VENTILATOR AND CONTROL METHOD THEREOF

摘要

Disclosed is a device for preventing dew condensation in a heat exchange type ventilator and a control method thereof, which measures an indoor and outdoor temperature and humidity in the heat exchange type ventilator and calculates a dew condensation temperature using them, and then the ventilator is automatically operated when the indoor temperature reaches the dew con¬ densation temperature, so as to control the indoor temperature, thereby preventing dew con¬ densation. The device includes: a heat exchanger; an air supply fan and an exhaust fan; a first temperature sensor and a first humidity sensor; a second temperature sensor and a second humidity sensor,; a dew condensation temperature calculating unit; and a controlling unit.
