摘　　要：给出了热水供热系统热力工况计算的基本公式。以直接连接热水供热系统为例,建立了热力工况定解方程组及矩阵方程。分析了供热系统未进行初调节、用户散热器面积偏离设计值及用户实际热负荷偏离设计热负荷3种情况下热水供热系统热力工况的变化及其热力失调的特点。Presents the fundamental calculation formulas for thermal condition of hot water heat supply system.Taking the direct hot water heat supply system as an example,establishes the determined system of equations for thermal condition and matrix equations.Analyses the variation of thermal conditions and the characteristics of thermal misadjustment under three conditions,including heat supply system without initial adjustment,deviation of user radiator area from the design value and deviation of the actual heat load from design heat load.
