Abstract
On account of regional energy structure optimization, scheme of hot water heating source is deeply studied. A comprehensive evaluation index system of heating source is established in terms of economic, energy efficiency, environmental protection, technology and policy. Combining the fuzzy comprehensive evaluation and AHP, the optimal scheme is determined. The air-source water heater is the relatively satisfactory scheme. The research will have an important effect on a wide range of residential buildings in china, which is also in favor of optimizing regional energy supply structure. The conclusion will push related industry to be energy-saving, secure and sustainable, provide important theoretical basis for energy planning on decision-making of city development, and provides an important reference for engineering design.
