摘要
相变储能技术的发展和昼夜电价分时制的实行为电采暖在北方寒区推广应用提供了可行性.数值模拟在初次和稳定蓄放热过程中,相变墙板温度和热流密度随时间变化,研究相变厚度、相变温度和相变半径对相变墙板传热过程的影响规律,并确定出适宜于寒区电热膜采暖系统的相变墙板,使该相变电采暖系统不仅具有热舒适性,而且能将夜间的低价电能储存起来供白天采暖用,降低电采暖系统的运行费,并对电网起到调峰作用,在宏观上具有节能效果.
PCM wallboard＇ s thickness, phage 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.
