The Energy-Saving and Carbon Emission Analysis of Solar-Assisted Air Source Heat Pump System for Hot Water Supply

Abstract:

The innovation of solar water heating system of students living community in Shanghai Ocean University is illustrated in this paper. A new water heating system including solar, air source heat pumps and gas boiler is established owing to the high energy consumption of original system. The comprehensive energy consumption, carbon emission and operating cost comparison between the original and new system is analysed based on the measured water, power and natural gas consumption. The results show that the comprehensive energy consumption is reduced by about 27.5%, the carbon commission decreased by 6%, and the operating costs reduced by approximately 23.6%, which means the new hot water system is successful.
