Matching study between PCM wallboard and electric-heating-film system in cold area

PCM wallboard's thickness,phase change temperature and temperature range can influence wallboard heat transfer course.By numerical simulating a series of PCM wallboards' heat transfer course,some rules of PCM heat transfer changing are concluded.Considering these rules and heating system in cold area,a PCM wallboard which fit electric heating thin-film system is chosen.Using this wallboard,electricity heating system can stores the cheap electricity energy at night and release the energy to room during the day.By this way the electricity heating system can save energy,and run with a low fee.
