【摘要】 在充分考虑北方地区夏季昼夜的气候条件和国家节约用电的峰谷电价差政策的基础上,利用DSC进 行了相变储能材料性能测试与分析,优选出2种脂酸类相变材料制成相变储能墙板,进行了相变墙板热性能 分析。研究表明,相变墙体在北方寒冷地区节能建筑中应用,可以利用我国北方城镇丰富的自然冷风条件,符 合国家有关调低乡镇居民电价和电力移峰填谷政策,不但能降低供热空调系统的投资与能耗,而且也是一种 改善建筑能耗对环境负面影响的有效途径。更多还原

【Abstract】 Phase change energy storage application becomes an academic focus of the world in building energy-conservation. In consider climatic conditions, summer day and night time of Northern country and foundation of policy of electricity at the peak-valley electric price differential, utilize DSC to test and analyze the material function of phase change energy storage, select two kinds of fatty acid as phase change material and make phase change wallboard, carry on thermal functional analysis of performance of the wallboard. Studies have shown, putting phase change wallboard into application in cold area of the North can utilize abundant natural cold wind terms of our country northern cities and towns, and this will accord with the policy of national development and reform committee of decreasing price of electricity and electricity for resident of villages and towns, moving peak fill out the valley, it will not only reduce heating investment and energy consumption of air conditioning system, but also will be an effective way for improving negative effect caused by building energy consumption to the environment.更多还原
