夏季工况相变墙房间蓄冷特性分析
Research of Cool Properties of Phase Change Wallboard Room in Summer
【摘要】 目的利用户式空调蓄冷,进行普通墙房间和相变墙房间夏季工况蓄冷时间规律的实测分析.方法以温度、热流巡检装置对实验房间的温度场和热流变化进行测试,得到在夏季工况下相变储能墙板对室内温度变化的影响情况.结果通过对夏季工况下普通墙房间和相变墙房间室内热性能参数的实测对比分析,得到相变墙房间中的相变墙板会减小室内温度波动,降低由室外通过围护结构向室内传递的热量,相变墙房间空调的启停次数要明显小于普通墙房间空调的启停次数,5h的蓄冷时间会得到较好的效果.结论在建筑围护结构中,加入相变储能构件,具有调节室内温度,提高室内热舒适性的特点,同时还能降低空调设备的开启频率,减少设备初投资和运行费用,并且能够对电力的“移峰填谷”起到一定实际作用.
【Abstract】 Through the tests and analysis of the parameters of the indoor thermal property in phase change wallboard room and ordinary room,the effects of phase change wallboards on indoor temperature in summer are obtained.The combination of construction enclosure with phase change materials can stabilize indoor temperature,improve indoor thermal comfort,reduce the frequency of the operation of air conditioning facility,cut the initial investment and operation expense,and meanwhile play a practical role in "the power balancing between the peak period and the valley period" policy.
