摘要
利用生命周期评价方法(LCA)对土壤源热泵与空气源热泵在节能和CO2减排效益方面进行研究比较,考察了土壤源热泵相对于空气源热泵的能耗回收期(EPT)和CO2回收期(CPT)两个指标,结果表明,整个生命周期内土壤源热泵较空气源热泵节能91829.64t标准煤,CO2减排262.5t,相对能耗回收期为2.87a,CO2回收期为0.89 a。
Studied the benefits of energy conservation and CO2 emission reduction of ground source heat pump(GSHP),compared with air source heat pump(ASHP),using life cycle assessment method(LCA).Considered energy pay-back-time (EPT) and CO2 pay-back-time(CPT),relative to air source heat pump,the results show that the amounts of energy conservation and CO2 emission reduction are 91829.64tce and 262.5ton,the energy pay-back-time is 2.87 year,the CO2 pay-back-time is 0.89 year,the ground source heat pump has very good benefits of energy conservation and CO2 emission reduction.
