基于逐时太阳辐射强度与动态逐时负荷分析的太阳能空调系统设计要点研究——以天津市某办公楼项目为例

Main Points of Solar Air-conditioning System Design based on Hourly Solar Radiation and Dynamic Analysis of Hourly Load:An office building in Tianjin

建筑的地理气候特征影响太阳能在建筑中的收集与利用。以天津市某办公楼项目为例,基于日照遮挡模拟分析确定集热器布置区域,并根据逐时动态冷负荷与热负荷综合情况确定集热器面积,以动态逐时负荷与供热(冷)量匹配的方法辅助备用能源设计,降低了系统的造价,提高了太阳能的利用率和建筑供能系统的稳定性,为后续其他项目太阳能空调系统的设计提供了借鉴。

Geographical and climate characteristics affect the collection and utilization of solar ener-gy. An office building in Tianjin is studied to illustrate the method of heat collector arrangement based on sunshine shading analysis, decide the heat collector area based on dynamic hourly cooling load and heating load, and assist the energy design through matching between the dynamic hourly load and heating （cooling） supply. The cost is lowered; and both the utilization of solar energy stability of building energy supply sys-tem are improved. The paper provides a reference for the design of solar air-conditioning system of the fol-low-up of other projects.
