“相变储能是一种先进的储热技术,在谷电时间采用相变储能技术进行电热蓄热,并将电热蓄热应用于建筑供暖,对电网的电力调峰以及用户供暖运行成本都具有很好的价值。本文对相变蓄热技术及产品进行具体分析,同时对采用谷电蓄热供暖的北方典型的商业建筑进行详细监测并分析。”目前我国建筑能耗已经占到整个社会能源消耗的40%,而制冷和供暖又在建筑能耗中占40%以上。在所有建筑类型中,商业建筑由于其建筑使用特性决定了具有较大的单位能耗。商业建筑一般都 “Phase change energy storage is an advanced heat storage technology, the use of phase change energy storage technology in the valley time electric heat storage, and electric heat storage for building heating, peak power grid and user heating operation Cost has a very good value.This paper carries on the concrete analysis to the phase change thermal storage technology and the product, simultaneously carries on the detailed monitoring and the analysis to the north typical commercial building which uses the valley electricity thermal storage heating. ”At present our country building energy consumption has accounted for To 40% of the energy consumption in society as a whole, while cooling and heating account for more than 40% of building energy consumption. In all types of buildings, commercial buildings have greater energy consumption per unit due to their use of buildings. Commercial buildings are generally
