During cogeneration of heat and power, the amount for unit heat consumption fuel is won in the gambling of thermal source efficiency；When heat source is source pump, thermal source efficiency is then
Correspond to unit COP (Coefficient Of Performance, the conversion ratio between energy and heat).And then, then root
According to total energy consumption=confession thermal energy consumption+conveying energy consumption, i.e. can get a series of total energy consumptions of heating network.
After total energy consumption under processing center calculates alternative each duty parameter, select minimum total energy consumption therein
As optimal solution, by this moment corresponding flow temperature, feed back each regulation equipment as the duty parameter under this meteorologic parameter, i.e. supply
Thermal source, a secondary net water pump, secondary net water pump and multifunctional pump etc..
In sum, it by being attached to the tune of heating network by the heat dissipation properties information of the radiator of heating network end
During control so that the regulation and control of heating network are more fitted practical operation situation, thus also effectively reduce the total of heating network
