간헐난방주택에 대한 외기온도 예측제어 적용 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 (3×4.4×2.8 m) identical in construction was built. The facility enabled simultaneous comparison of two different control method. And real multi residential house was investigated. Results showed that outdoor air temperature prediction control was superior to the conventional control for radiant floor heating system operated in the intermittent heating mode. New control system resulted in good thermal environment and less energy consumption.
