Design and Analysis of Energy Conservation and Environmental Protection for a Sewage Source Heat Pump District Energy Supply System in Xi'an
This paper takes a sewage source heat pump district energy supply system in Xi'an as the research object. Firstly,through the analysis of test data,the water quality,temperature,and quantity of the water source are found to meet the requirements for the use of sewage source heat pumps. Secondly,the design of the sewage source heat pump district energy supply system is introduced. Finally,an analysis is conducted on the energy-saving and environmental-friendliness of the sewage source heat pump system for heating compared to gas-fired boilers. The analysis results show that the sewage source heat pump system can save 2,707tons of standard coal per year compared to gas-fired boilers,with an energy-saving rate of approximately 48％. It can also reduce emissions of 7,092tons of carbon dioxide,23tons of sulfur dioxide,20tons of nitrogen oxides,36tons of PM10,and 29tons of PM2.5 annually. The application of the sewage source heat pump system exhibits significant energy-saving and environmental protection benefits.
