Fundamental calculation formulas for thermal condition of hot water heat supply system and thermal misadjustment

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.
