在供热区域热舒适性及室内空气品质满足要求的前提条件下，通过分析从热源提取热量到最终释放到供热房间的整个环路的能流情况，分别建立了以空气源热泵热水机组和燃料燃烧的热水锅炉为热源的集中空调供热系统的整个环路的能流数学模型，并进行了对比分析。并以广州某酒店冬季供热系统为例，绘制了该系统在设计条件下，分别采用上述两种不同热源条件下完整的集中空调供热系统的能流图，直观地表现了这两种系统中各部分能流的大小和方向、能量平衡关系及能量损失以及它们之间的主要差别。识别出两种系统中主要的能流，可以为空调热源的优选及所选系统的节能降耗提供有用的信息。

In order to meet the requirement of the heating thermal comfort and indoor air quality, the en-ergy flow mathematical model for the central air conditioning system with air-source heat pump water chil-ler and fuel combustion boiler were established in sequence to finally determine global energy flow through analyzing the comparative energy flows of the consecutive loops which begin from extraction energy from the environment and provide it to the conditioning space.As a case study, the two energy flow diagrams of heating modes with different heat sources at a hotel in Guangzhou were drawn respectively, which can visualize each energy flow, energy balances, energy losses and their main differences.Recognizing the main energy flow of the two heat sources can provide useful messages for selection and energy saving of heating mode of conditioning system.
