The Research Of Hefei Heating Pipe Network Current Situation And Development

HeFei as the Yangtze River region, a medium-sized city, the average temperature below 5℃for about 90 days, is a typical hot summer and cold winter zone. With the growing demand for people, HeFei heating is developed rapidly in recent years, the heating pipe network basically covers the main urban areas. However, Hefei with a relatively short heating time, and more single heating user, belongs to non-mandatory heating area. Many factors have led to higher heating costs. Therefore, how to reduce heating costs are urgent problems, which is to the development of Hefei heating has important significance.This paper is according to HeFei heating pipe network and the distribution of heat users, to make a systematic analysis of the entire pipe network, and obtained the existence of some problems. At the same time using exergy economic theory to hydraulic pipe network calculation, pressure loss and heat loss will be analyzed together to overcome the non-comparability between then. The theory can be used as both a pressure and heat pipe network analysis.Finally,to HeFei heating pipe network as an example, using exergy analysis of the theory obtained pipe network parameters on the impact of the cost of the entire pipe network, and reaction problems in the form of data. Also analyzed the economics of the different heating methods.
