    Abstract

    With the transformation of China's development mode and energy structure, "double control" of energy consumption and clean and centralized alternative heating by burning coal have become an inevitable trend. The study focuses on efficiency evaluation of clean heating, a dynamic and systematic problem, which involves technical, financial, economic and social evaluation. At present, the evaluation of heating mode generally focuses on the economic and technical perspectives, which, to a certain degree, cannot reflect the deep problems of economy, society, environment and resources. Taking Xi'an as an example, this paper evaluates the air source heat pump, gas-fired boiler and the multi-energy complementary heating scheme based on shallow geothermal energy. By adopting the method of systematic evaluation, based on the DPSIR model, we determined the factor indexes of each subsystem in the evaluation model, constructed the comprehensive performance evaluation index system of clean energy heating, and calculated the single-level and comprehensive evaluation values of each subsystem of clean energy heating by using the grey relational degree model of AHP-POS, and analyzed the relationship and interaction mechanism of the influencing factors.
