Abstract


Central heating has become a major form of heating in northern China, heatingcentral heating have obvious advantage in energy saving compared with thetraditional boiler room and the saving is a great potential. There is always too muchheat in the process of heating, leading to phenomenon that thermal users appear coldand hot uneven, and some users’ indoor overheat can only be solved through awindow, and some users’ indoor temperature is too low. In order to solve heatingdisorder heating system problems and reduce the energy waste during the operation ofheating system, it is necessary to regulate and control in heating system. Four-waywater mixers heating system can solve effective the overheating, and it makespossible to regulate the heat load by users themselves, and the heat source avoids thenoneffective heating. This article research will revolve around the operationadjustment and control of the heating system for related research based on four-waywater mixers.First, form of heating system based on cross water mixer are studied, and energyequation of four-way water mixers installed in mixed water stations and thermalentrance to the building are deduced, and presents water than the definition of the typeand the calculation formula of a four-way mixed water.Second, the operation adjustment and control of the heating system are studied,the adjustment formula of six different combination adjustment which is applicable tothe heating system are derived,and draw the corresponding curve adjustment and inview of the six combined adjustment control scheme is given.Finally, the corresponding operation adjustment calculation of heating systembased on four-way mixed water according to the actual heat supply planning projectof jidong are researched, and analyze a total power consumption of circulating waterpump of first and second network under six kinds of regulation scheme. Consider thesystem trait, run feasibility of adjustment, cost of network operation and so on, selectthe best regulation mode.
