Application and Benefit Analysis of Sewage Source Heat Pump Technology
摘要
Abstract
Urban sewage discharge is enormous and contains abundant waste heat energy.Utilizing sewage source heat pump technology to output energy in the form of heating and cooling is an important approach to achieve carbon neutrality,which is of great significance for the low-carbon and environmental protection development of the industry.To identify the differences in economic and environmental bene-fits among different heating systems of sewage source heat pumps,this study takes the office building of a sewage treatment plant in Anhui Province as a case study,comparing the investment and operating costs of direct sewage source heat pump,indirect sewage source heat pump and air source heat pump.The results show that the total investment of the direct sewage source heat pump is 16.5%lower than that of the indirect type and 30%higher than that of the air source type.Its operating cost is 7.2%lower than the indirect sewage source heat pump and 73%lower than the air source heat pump,with a financial internal rate of return(FIRR)of 8.26%and a dynamic pay-back period of 7.5 years,demonstrating excellent economic benefits.In addition,compared with the air source heat pump,the direct sewage source heat pump can save 7.28 kWh of electricity annually,reduce CO2 emissions by 2400 kg,SO2 by 3.0 kg,NOx by 1.2 kg,and PM2.5(Particulate Matter 2.5)by1.0 kg,showing remarkable low-carbon and environmental protection benefits.关键词
