TECHNICAL ECONOMIC MODEL OF ENERGY UTILIZATION AND ENERGY SAVING FOR CENTRAL HEATING SYSTEM

ABSTRACT
Chinese heating method has gradually shifted from small fragments to centralized regional heating. This heating method has achieved obvious energy-saving benefits. The article establishes an economic model of the energy utilization rate of the central heating system and installs the system exergy balance equation at the same time. The simulation found that the energy utilization coefficient of the heating system is high and has a high energy-saving potential. The effect of energy utilization is poor, and it has great potential for energy saving.
KEYWORDS
central heating energy analysis, exergy analysis, energy efficiency, exergy efficiency, economic benefits
