从热力学角度对能量品质和热力系统的进行分析,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。
Analyze the energy quality and the thermodynamic system from the thermodynamic point of view, and propose a method to analyze the efficiency of different heating systems. By analyzing and comparing the energy of different heating systems, it is concluded that the overall energy utilization of water source heat pump plus floor radiant coil heating is most economical and reasonable. However, in the absence of low temperature hot water residual heat of 30 ~ 35 ℃, high temperature water source heat pump radiator Heating system is less economical. The energy analysis of the heating system compares the advantages and disadvantages of various heating systems in nature, and provides theoretical guidance for the reasonable choice of heating system.
