전열교환기의 동계 운전 결로 억제에 관한 연구

An experimental study was performed to reduce the condensation during the winter operation. The hydrochromic ink was used to detect the condensation in the total heat exchanger. The condensation within the total heat exchanger during the winter operation occurs at the cold wall of the exhaust air. When the air flow rate of the exhaust air is decreased, the condensation temperature of the exhaust air becomes lower and therefore, the condensation is reduced. While the decreasing air flow rate of the supplied air promotes the condensation by raising the condensation temperature of the exhaust air within the total heat exchanger.
