Abstract

Due to the lack of suitable evaluation systems for heating, ventilation, air-conditioning (HVAC) systems with ground source heat pump (GSHP) and energy storage (ES) technologies, it is difficult to design a building HVAC system to achieve optimized design with regard to investment cost, energy saving and environmental protection. This is a study on developing a fuzzy evaluation system by including GSHP and ES with comprehensively determined weights into an HVAC system. A questionnaire method was used and the answers from 21 HVAC experts were analyzed to facilitate the modeling. Taking a commercial integrated project in Nanjing as an engineering case, the evaluation system was tested. If the system with a comprehensive merit value of 0.303 is adopted, the annual operating cost is reduced by 32.5%, the annual total life cycle cost is reduced by 26.5% and the primary energy consumption and carbon emissions are reduced by 10.5%, with the initial investment increased by 6.5%. This study revealed that the newly developed evaluation system is very useful for realizing the optimal design of HVAC systems.

暖通空调系统优化设计GSHP和ES技术评价体系研究

摘要

由于缺乏适合地源热泵（GSHP）和储能（ES）技术的供暖、通风、空调（HVAC）系统的评估系统，很难设计一个建筑暖通空调系统以实现优化设计。投资成本、节能环保。这是一项通过将综合确定权重的 GSHP 和 ES 纳入 HVAC 系统来开发模糊评估系统的研究。使用问卷调查法对 21 位暖通空调专家的回答进行分析以促进建模。以南京某商业综合项目为工程案例，对该评价体系进行了测试。如果采用综合价值为0.303的系统，年运行成本降低32.5%，年全生命周期成本降低26。5%，一次能源消耗和碳排放减少10.5%，初期投资增加6.5%。这项研究表明，新开发的评估系统对于实现暖通空调系统的优化设计非常有用。
