Exergy Analysis of Hot-water Heating System Conditioning Methods

摘要：

　　The reasonable heating regulation directly affect the heating of the economy, and thus its exergy analysis is imperative.In order to optimize the heating system, three regulation methods used in heating system are analyzed in this paper.They are quality regulation, flow mass regulation and stage-flow-mass-changing quality regulation.Each method has a different effect on energy saving and energy loss.Based on the second law of thermodynamics, this paper analyzes the total energy loss of these three methods by dividing the heating system into subsystems including boiler, indoor heat dissipation equipment and outdoor pipe network and the circulating pump.It is demonstrated theoretically that flow mass regulation is the best way for saving energy and quality regulation is the worst.
