간헐난방시스템에서의 외기온도 예측제어 적용에 관한 연구

Most of radiant floor heating systems are operated in the intermittent heating mode in Korea. The application possibility of predictive suboptimal control for Korean residential house was investigated by computer simulation and experiment. For this study, TRNSYS program was used and an experimental facility consisting of two rooms(3×4.4×2.8m) identical in construction was built. The facility enabled simultaneous comparison of two different control strategies. Results showed that outdoor air temperature predict control was superior to the conventional control for radiant floor heating system operated in intermittent heating mode. The new control system resulted in good thermal environment and less energy consumption.
