| Summary: | Life cycle assessment method was used to evaluate the full life cycle carbon emissions of a kind of hybrid-power gas engine heat pump. With the system boundaries and the accounting mode established based on the life cycle (LCA) assessment, the carbon equivalent emissions in the periods of production, transportation and installation, operation and recycling of the system are figured out respectively .The results show that the system CO2-eq emissions (35387.6kg) is the highest in running phase, accounting for approximately 84% of the entire life time, and the main source is from the usage of electricity and natural gas; followed by the production phase which are approximately 6178kg;the transportation-installation phase and disposal phase can be neglected because of their low carbon emissions. Therefore, in order to reduce the greenhouse gas emissions of the system in the full life time, more attentions should be paid to the rational use of electricity and natural gas and the development of new energy. Secondly, its carbon emissions are compared with separate power-driven heat pump, and the analysis results show that hybrid-power gas engine heat pump could reduce 20430.9kg carbon emissions. Finally, carbon emission reduction method and emission reduction potential of the system are further discussed. |
