            摘要:

            通过对建筑热负荷方程、散热末端散热方程、管网热输配方程的分析和联立求解,推导出了不同散热末端下定流量供热系统的质调节方程。分析了质调节对电动蒸气压缩式热泵机组制热性能系数的影响,并结合模拟计算,分析了不同散热末端逐日质调节与逐时质调节在定流量热泵供热系统中应用的节能潜力。

            Abstract:

            Based on the analysis and simultaneous solution of the building heat load equation, the heat dissipation equation of the heat terminal and the heat transfer and distribution equation of the pipe network, deduces the quality regulating equations of constant flow heating system with different heat terminals. Analyses the influence of quality regulating on the heating performance coefficient of electric steam compression heat pump units. Combined with the simulation calculation, analyses the energy saving potential of daily quality regulation and hourly quality regulation at different heat terminals applied to the constant flow heat pump heating systems.
