摘要
针对西藏高原丰富的太阳能资源条件和迫切的供暖需求,提出了离网光伏条件下,光伏+空气源热泵+蓄电、光伏+空气源热泵+蓄热、光伏+电采暖设备+蓄电三种离网光伏供暖技术形式.以西藏日喀则市某孤立地区居住建筑为研究对象,建立三种"光伏+"供暖系统仿真模型,重点分析了光伏面积、蓄能容量对系统太阳能保证率的影响.结果表明:三种系统中光伏+空气源热泵具有较高的能源利用效率,所需光伏面积较少;当蓄能形式为蓄热时,光伏+空气源热泵系统所需的蓄能设备容量较小,太阳能保证率较高.
In view of the abundant solar resource conditions and urgent heating demand in the Tibet Plateau, three off-grid photovoltaic heating technology forms are proposed, which are photovoltaic + air source heat pump + electricity storage, photovoltaic + air source heat pump + heat storage and photovoltaic + electric heating equipment + electricity storage. Taking isolated area residential building in Shigatse, Tibet as the research object, three simulation models of “photovoltaic +” heating system were established, focusing on the analysis of the impact of photovoltaic area and energy storage capacity on the solar fraction of the system. The results show that the photovoltaic + air source heat pump of the three systems has higher energy efficiency and requires less photovoltaic area, which should be promoted first. When the energy storage form is heat storage tank, the capacity of energy storage equipment required by the photovoltaic + air source heat pump system is smaller and the solar faction is higher.
