摘要/Abstract

摘要： 以长沙地区某南向设窗的实验房间为研究对象,采用EnergyPlus能耗模拟软件建立辐射地板结合风机盘管供冷空调系统的数值模型,并通过实验验证该模型的可靠性。通过规范计算及模拟分析量化不同窗墙比下太阳辐射得热对该系统中辐射地板供冷能力及风机盘管系统设计容量的影响,并提出一种在太阳负载下辐射系统容量预测的简化方法。

关键词: 太阳辐射, 数值模拟, 供冷系统, 窗墙比, 系统容量, 辐射地板

Abstract: Taking a south-facing windowed experimental room in Changsha as the research object, a numerical model of radiant floor combined with fan-coil cooling system is established using EnergyPlus energy consumption simulation software and the reliability of the model was verified by experiments. Through calculating by standard and simulation analysis, the influence of solar radiation heat under different window-wall ratios on the cooling capacity of the radiant floor and the design capacity of the fan coil system is quantified; a simplified method for predicting the capacity of the radiant system under solar load and is proposed.

Key words: solar radiation, numerical simulation, cooling systems, window-to-wall ratio, system sizing, radiant floor
