Abstract
Based on the energy and site conditions of the current terminal building of an airport in a cold region,three transitional air conditioning cold and heat source schemes,namely gas boiler+centrifugal chiller,low ambient temperature air source heat pump+gas boiler,and shallow ground source heat pump+gas boiler,are introduced.By calculating indicators such as the static payback period,life cycle cost and carbon emissions,the various schemes are compared and selected.The results show that the initial investment of scheme two is at a medium level,the operating cost advantage during the transition period is obvious,the operating cost during the operation period is at a medium level,the life cycle cost is the lowest,and the carbon emissions are the least.From the perspectives of economy and energy-saving and emission reduction,it is more appropriate for the airport terminal building to adopt a low-ambient temperature air source heat pump+gas boiler as the cold and heat source solution during the transition period.关键词
