Abstract

IT-based automatic controller that control the temperature and humidity to prevent dew condensation of distributing board was designed and implemented in this paper. The dew condensation temperature was deduced from room temperature and humidity of distributing board. Based on the comparisons between the deduced dew condensation temperature and the temperature of surface condensation, the facilities that can prevent the condensation was implemented to be operated in due order. Also, the remote monitoring module to monitor operation status of controller was implemented using LoRa technique. The performances for controller operation and data transmission were validated from the transmission and operation test for dew condensation prevention. The controller can be put to good use at the facilities that requires the condensation prevention.

본 논문에서는 옥내 외에 설치 운영되는 수배전반의 결로 현상을 방지하는 IT 기반 자동 온습도 제어기를 설계하고 제작하였다. 이슬 결로점 온도가 실내공간의 습도와 온도로부터 산출되고, 이슬 결로점 온도와 결로 부위의 온도를 비교하여 수배전반의 결로 현상을 방지할 수 있는 시설이 순차적으로 제어 동작되도록 구현하였다. 아울러 원격지의 수배전반의 결로 기반 제어기 동작 상태를 모니터링 할 수 있는 원격 모니터링 장치를 LoRa 무선통신 방식을 사용하여 구현하였다. 제어기와 원격 모니터링 장치를 설치 운영하여 전송되는 데이터의 정확성과 결로 기반 제어기 동작상태의 안정성을 확인하였다. 본 제어 장치는 수배전반 이외에 결로가 발생되는 장비에 설치되어 결로를 방지할 수 있는 장치로 용이하게 활용될 수 있다.
