Quality regulating equation solution of constant flow heating systems and application to heat pump heating systems

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.
