Regulation Of Multi-source Network Running

The technique of multi-source network is developed in the foundation of synthesize the application of adjusting soon technique and controlling technique of pump as to economize the energy lower the system movement cost and increases economic performance in the abroad countries that have advanced in heat-supply. In recent years, China's urban central heating has been the rapid development and popularization of the heating heat users are also getting higher and higher quality requirements, at the same time, heating enterprises attached more importance to the improvement of economic efficiency. Due to multi-source network-conditioning system has a convenient working conditions, hydraulic stability and the advantages of reliable operation, their use is widespread. At present, the operation of multi-source network theory and technology is not yet mature, the lack of theoretical guidance in practice.In this paper, we based on cyclic heating pipe network joint operational regulation and technical work experience obtained in two dual heat source heating period, analysis the loop multi-source co-heating pipe network design and operation. And based on conditions of a comprehensive analysis of networking in a multi-source status of the operation of hydraulic and thermal the principle of multi-source networking technology to conduct research, draw more heat in the heating network energy consumption, operating costs, system reliability with regard to the advantages, as well as the heat network to achieve more than the conditions. In addition, a brief analysis of central heating by the Bank set up surveillance systems, as well as tasks. We integrate with the actual situation of central supply heat system in Chengyin of Daqing to determine a reasonable proportion of load matching of the heat source, and computational analysis of the hydraulic operating conditions in network of working conditions, worked out a reasonable regulation of the operation of heating system program.
