Comparative Analysis Between the Traditional Air-Condition System and Heat Source Heat Pump System of Northern Existing Buildings Based on AHP

Types and proportion of air conditioning heat and cold sources of northern existing buildings including government office buildings, large public buildings and civil architectures are illustrated in the paper based on detailed investigation. On the basis of selection, energy consuming, life cycle cost and payback period of investment, environmental and social benefits, analytic hierarchy process (AHP) is used to decide the best scheme of heat and cold sources which is a multi-attribute decision-making methodology widely used by researchers. A form of multi-energy supply is proposed in the paper. The applicability and feasibility of it was verified by analysis of a practical example.
