VENTILATION SYSTEM TO PREVENT OVER-HUMIDIFICATION

摘要

The present invention relates to a ventilation system for automatically controlling the humidity of a room. The ventilation system comprises: a temperature moisture sensor which measures the temperatures of outdoor air and indoor air and indoor humidity; a controller which receives the measured value by temperature moisture sensor, calculates a condensation generation condition and transmits operation signals; and a total heat exchanger which is operated by receiving the operation signals transmitted from the controller. The temperature moisture sensor comprises an outdoor air temperature sensor for measuring the temperature of outdoor air and a room temperature moisture sensor for measuring indoor temperatures and outdoor temperatures and prevents the condensation generation of a room. The controller calculates the condensation generation condition by calculating a saturated water vapor pressure and dew point temperature with a second-order polynomial approximation formula.
