초록

우리나라의 석유화학산업단지는 폭발성 가스와 가연성 가스로 인하여 언제나 폭발 위험성이 높다. 이러한 폭발을 방지하기 위한 방법으로 석유화학산업단지의 대부분 설비에 방폭 성능을 요구하고 있다. 방폭용으로 현재 사용하고 있는 제어기 패널은 패널의 내부와 외부의 압력(양압)과 온도를 일정하게 유지를 위해 외부에서 수동으로 공기를 주입하는 방식을 사용하고 있다. 이에 본 논문은 자동으로 온도를 제어할 수 있도록 패널 내부의 온도에 따라 가열과 냉각을 자동으로 수행하는 자동 온도조절기를 제안한다.

Petrochemical industry complex in Korea always has high riskiness due to explosive and inflammable gases. To prevent these explosion, most facility of petrochemical industry complex requires the performance of explosive proof. The control panel, which is used as explosive proof, has been used the air injection method by manually from outside to constantly keep the temperature and pressure between inside and outside of the panel. In this paper, we propose the automatic temperature controller, which performs automatic heating and cooling according to temperature inside the panel in order to control temperature automatically.
