Micro- rising.On the other hand, if supplementing the heat using heat power supply device A, operation point is mobile from α (401) to α ' (402).At this
In the case of understand, due to heat power supply device A more powerful amplitude rise, therefore with situation about being supplemented using heat power supply device B
Compare, the energy consumption sum of heat power supply device A, B is reduced.Particularly, as shown in figure 5, there are multiple demand resident families with heat
The source device and type of flow is without under the such situation of well-determined pipe network 501, changes radiating using the type of flow
Amount, does not occur corresponding method in previous methods.
On the other hand, the control device 101 of the region thermal energy supply network of the present invention is characterised by, it is contemplated that its radiating.
By using number 9, can include to be calculated in optimization is calculated by stream and with respect to the heat dissipation capacity in its path, therefore can
Enough optimizations that realizes in view of radiating.If object function is specifically write out, become the overall consumed energy of system, shown with number 10
Go out.Here, EARepresent the consumed energy of heat resource equipment A, EBRepresent the consumed energy of heat resource equipment B.

Also, represent the electric power of pump using several 4 sums 5.
Using these formulas, represent whole power consumption of the region thermal energy supply network shown in Fig. 6 using following number 13.This
In, Ea' represent pump A use energy, Eb' represent pump use energy.
[number 13]
E=EA+EB+E′a+E′b
In order that the value is minimum and sets target function, same as Example 1, with the mass flow of each pipe network, thermal source
The rate of load condensate of device and connection cut-out variable (0 or 1) set up operating plan as variable using optimal computing section 105, by
This being capable of energy-conservation.
[embodiment 3]
Fig. 7 illustrates the application examples i.e. embodiment 3 of the control device 101 of the region thermal energy supply network of the present invention.Except thermal source
Also there is exhaust heat source 701 outside device A301, by pipe arrangement heat supply from heat exchanger 702 to region thermal energy supply network.It is flowed into and changes
The mass flow of hot device 702 is determined by pump 703, is also equipped with conveying, for specifying, the thermal medium for being received heat supply using heat extraction
Which valve 704 and valve 705 to supplying tubing net 305 or return pipe network 306.
Now, the control device 101 of region thermal energy supply network predicts exhaust heat source 701 using heat exhaust prediction section 103

Fig. 9 illustrates the application examples i.e. embodiment 4 of the control device 101 of the region thermal energy supply network of the present invention.Here, except
Also there is natural energy outside heat power supply device A301 using thermal source 901, by pipe arrangement from heat exchanger 702 to region thermal energy supply network
Heat supply, using pump 703 determine be flowed into heat exchanger 702 entirety mass flow, be also equipped with for specify will be using natural energy
Amount receive the thermal medium after heat supply be delivered to supplying tubing net 305 or return which valve 704 in pipe network 306 and
Valve 705.
Now, the control device 101 of region thermal energy supply network reads weather forecast, actual achievement number before this from database 107
According to and predict the hot water temperature generated based on this.The hot water temperature exported with heat power supply device A301 is compared, if the hot water of prediction
Temperature is higher than the hot water temperature exported by heat power supply device A301, then open valve 704 and shutoff valve 705 is to supplying tubing net 305
Heat supply.Though in the low hot water that exported than heat power supply device A301 of being unable to reach of the temperature of the thermal medium of the heating because of natural energy
The high temperature of temperature but in the case of can reaching than returning the high temperature of hot water temperature in pipe network 306, shutoff valve 704 is simultaneously
Open valve 705 and carry out heat supply.In addition, in the case of it cannot raise the hot water temperature in return pipe network 306, making the matter of pump 703
Amount flow is 0, in the lump shutoff valve 704 and valve 705.Thus, in the presence of natural energy is using thermal source 901, Neng Goutong
Cross and be efficiently used its heat extraction to realize energy-conservation.
In specific calculating, similarly to Example 3 using the order of the flow process shown in Fig. 9.
