Decision of Air Conditioning Cold and Heat Sources Based on Analytic Hierarchy Process

The optimization model of analytic hierarchy process (AHP) is introduced firstly, and then using it, air conditioning cold and heat sources are decided in a project of Qingdao City. Considering economy, technical condition, environmental impact and social benefit, each of four schemes of air conditioning cold and heat sources is analyzed quantitatively by Excel software. Finally sea water resource heat pump system is selected. The results show that the AHP Excel algorithm is convenience in applying, but the application of this method should be based on specific cases.
