摘要
以某寒冷地区机场现状航站楼的能源和场地条件为基础,介绍燃气锅炉+离心式冷水机组、低环境温度空气源热泵+燃气锅炉、浅层地源热泵+燃气锅炉共3种过渡期空调冷热源方案。通过计算静态投资回收期、寿命周期成本和碳排放量等指标,对各方案进行比选。结果表明,方案二的初投资处于中等水平,过渡期运行费用优势明显,运行期运行费用处于中等水平,寿命周期成本最低,碳排放量最少。从经济性和节能减排的角度考虑,该机场航站楼过渡期选用低环境温度空气源热泵+燃气锅炉作为冷热源方案较为合适。
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.
