摘要
Abstract
An old residential area in Shandong province is located at the end of the central heating network.Due to the insufficient heating capacity of the network,heating cannot be realized.By adding energy-saving secondary stations and adopting three-channel efficient heat exchange technology to increase the heating capacity of the pipeline network,the energy-saving benefits and technical economy of this secondary station are compared with other three clean and low-carbon heating technologies based on actual operation data.The results show that the three-channel high efficiency heat exchange technology has certain advantages in energy saving and carbon dioxide emission reduction,among which the high temperature difference absorption heat pump heating technology has the highest energy consumption and carbon dioxide emission,which is 3.7 times of the three-channel high efficiency heat exchange technology.Air source heat pump heating technology is second,which is 2.1 times.The sewage source heat pump heating technology is slightly higher than the three-channel efficient heat exchange technology,which is 1.34 times of the latter.In terms of technical economy,the heating cost of three-channel efficient heat exchange technology is the lowest,which is 18.55 yuan/m2.The cost of sewage source heat pump and large temperature difference absorption heat pump heating technology is 24.85 yuan/m2 and 27.49 yuan/m2 respectively.The cost of air source heat pump heating is the highest,reaching 38.94 yuan/m2.关键词
