Research On Regulation And Energy Saving For District Heating System Based On Hydraulic Bleeder

With the continuous progress of human technology heating, central heating hasbecome China ’s main heating mode. Central heating in the living standards of the residents,but also to the construction industry is a big waste of energy, heating energy consumption inbuildings has become a top priority. In the existing central heating system, because thesystem in the form of common defects caused by energy waste problems, such as to make thesystem hydraulic imbalance excessive heating by heat, resulting in a large number of invalidenergy consumption, but also created new the Enthusiasm. Facilitate and regulate energyconsumption has become a central heating system trends.In front of people, I started learning outcomes, first expounded in the development ofheating technology at home and abroad, by comparison of the characteristics of traditionaland new heating system, the introduction of central heating systems based on hydraulicbleeder. This system taking into account the advantages of distributed heating systems anddirect-attached heating system, energy-saving effect and high heating efficiency, so I thinkthat the study of this system is necessary.Hydraulic bleeder is adapted to the characteristics of buildings adjustable watertemperature required to produce a new type of thermal network connected devices, withtwo-way mixing water. Through the hydraulic bleeder based central heating systems theoryanalysis, the hydraulic bleeder can be user-side heat pipe network separation, to avoidaffecting the user side heat conditions change on the network, while maintaining the heatingnetwork savings under the temperature difference constant energy transmission anddistribution pipeline network.Through the analysis of system operation regulation, identified regulation, such asadjusting the temperature difference between the way that system. In ensuring the heatingnetwork for the return water temperature constant, the hydraulic bleeder can run underdifferent levels of heating pipe temperature, the system can adapt to changes in heat loadvariable flow operation. Next, the control program of the heating system has been studied,regulation gives automatic control of distributed programs. By studying a variety of circulation pump arrangement, namely conventional heatingsystems, optimal layout scheme circulating pump and hydraulic bleeder-based comparativesimulation of energy-saving central heating system analysis, research shows that focus onhydraulic bleeder transmission and distribution of energy consumption of the heating systemrunning at least about59%of savings is worth promoting a new heating system.Hydraulic conditions through simulation found that the best location-based hydraulicbleeder central heating system almost zero pressure at the outlet of the heat source, on thisbasis, the proposed design should pay attention to some issues and ideas.Finally, the authors used graph theory to build a mathematical model of heating pipenetwork, through the model analysis, the numerical solution of heating pipe networkhydraulic calculation, and the use of C language for the heating system model for HydraulicCalculation process programming.
