Economic Analysis of Composite Energy Heating System in the Cold Region

摘要

This paper makes an analysis of the three heating mode of composite energy heating system compared with central heating. The composite energy heating system is also analyzed from the economic analysis, and the article expounds the superiority of composite energy heating system in some aspects. In terms of solar thermal storage heating mode, the reclaimed water source heat pump heating regenerative mode and composite energy heating mode, the paper carries out a detailed comparative analysis of the initial investment, annual operating cost and static payback period of these three areas. The result is that composite energy heating systems has higher initial investment but lower operating costs, combined static payback period of comparison, and the composite energy heating mode have significant economic benefits as well as a good prospect in market competitiveness.
