摘要
为深入了解某图书馆阅览室金属微孔顶板辐射空调系统的能耗及室内空气品质情况,通过对该空调控制系统终端运行数据进行采集,得出该空调系统冬、夏工况下的空调运行负荷及阅览室CO_2浓度,并进行了计算与经济分析。结果表明,该空调系统实际运行相对传统空调系统节能,投资回收期为9年。测试发现阅览室空气品质没有达到设计标准,CO_2浓度总体基本维持在720ppm^860ppm之间,分析是新风量不足所导致,提出了相应的改善措施。
To investigate the energy consumption of the micro-porous metal roof radiation air conditioning system operation and indoor air quality in a library reading room, the concentration of CO2 in the reading room was acquired through test experiment and the air conditioning operation load in winter and summer conditions was calculated. Then, by studying on energy saving of this system and economic analysis, it came to the conclusion that the air conditioning system provides superior performance on energy saving compared with traditional air-conditioning and its investment payback period is 9 years. Test indicated that the CO2 concentration in the reading room remained a high level a high level from 721） ppm to 860 ppm which was not up to standard for lacking of fresh air. Relevant measures were proposed to improve such conditions.
