本文介绍了爱尔兰高威的一个被动式住宅的太阳能集热器面积和太阳能存储量的参数分析。使用仿真工具瞬态系统仿真工具（TRNSTIM），开发了一个模型，代表了一个215平方米的家庭建造的被动式住宅标准，并结合了10.6平方米的太阳能集热器和23立方米的太阳能储热罐。该模型通过与在现场收集的数据进行比较，从家庭的运作超过1年的时间进行验证。一旦验证，该模型被用来研究不同的太阳能集热器面积和太阳能存储量对太阳能满足的热需求的比例的影响。结果表明，将集热器面积从10.6平方米增加到20平方米，可以将总太阳能比例从0.47增加到0.63，将研究中的家庭化石燃料能源需求进一步减少30%。
This paper presents parametric analysis of solar collector area and solar energy storage volume for a passive house in Galway, Ireland. Using the simulation tool Transient System Simulation Tool (TRNSYS), a model was developed to represent a 215 m2 home built to Passivhaus standards and incorporating a 10.6 m2 solar thermal collector and a 23 m3 solar thermal storage tank. This model was validated through comparison with data collected in situ from the operation of the home over the period of 1 year. Once validated, the model was used to investigate the effect of varying solar collector area and solar energy storage volume on the fraction of heat demand met by solar energy. Results indicate that increasing collector area from 10.6 to 20 m2 could increase total solar fraction from 0.47 to 0.63, decreasing fossil-fuel-derived energy demand at the home under study by a further 30%.
