摘要
从热力学角度对能量品质和热力系统的佣进行分析，提出分析不同采暖系统效率的方法。通过对不同采暖系统进行能量[火用]分析和对比，认为水源热泵加地板辐射盘管采暖形式的总体能源利用最经济合理，而在没有30-35℃的低温热水余热情况下，高温水源热泵暖气片采暖系统经济性较差。对采暖系统的能量士用分析从本质上对比各种采暖系统用能的优劣，为合理选择采暖系统提供理论指导。
Analyzes energy quality and exergy of thermal dynamic and proposes analysis method of various heating systems. Through exergy analysis and comparison of different heating system, the results show that water source heat pump combined with floor heating system is the most economic and reasonable, high temperature water source bump radiator heating presents poor economic performance without residual heat from water with the temperature of 30-35℃. Compares the advantages and disadvantages of various kinds of heating systems in order to provide theoretical guidance in rational selection of heating systems.
