【摘要】 闭式环路水源热泵空调系统作为一种节能型的空调形式被提出,但由于其所应用的地区、建筑及负荷特性各不相同、运行工况复杂,是否比常规系统节能不能简单定论。本文采用对比评价和数值模拟分析相结合的研究方法,借助eQUEST建筑能耗模拟软件对我国4个气候分区下的72个建筑模型进行模拟研究,并通过与常规集中式VAV空调系统的对比,对水环热泵空调系统的能耗和应用情况进行综合分析,总结气候特点、内区负荷、建筑规模、辅助热源的形式等关键因素对水环热泵空调系统能耗所产生的影响,初步得出水环热泵空调系统在我国的动态模拟评价结果。更多还原

【Abstract】 Closed loop water-source heat pump air-conditioning system has been used as a form of energy-saving air-conditioning.But due to the location,building and load characteristics varies,whether the energy efficiency of water loop heat pump air-conditiong system is higher than conventional systems can not be simply inconclusive.Combined comparative evaluation and numerical simulation analysis,72 architectural models from four climate divisions are simulated using eQUEST building energy consumption simulation software.Through comparing with the conventional centralized VAV air-conditioning system,the comprehensive analysis on the energy consumption and application of water loop heat pump air-conditioning system is conducted.The key influencing factors on water loop heat pump air-conditioning system’s energy consumption are summarized,such as climate characteristics,air-conditioning load of the inner zones,building size,form of auxiliary heat source and so on,and the dynamic simulation evaluation results of the water loop heat pump air-conditioning system in our country are get preliminarily.更多还原
