Fig. 3 illustrates application examples and the embodiment 1 of the control device 101 of region of the present invention heat energy supply net.Heat power supply device A301 and heat power supply device B302 generating hot water, this hot water is supplied to demand resident family 303 by supplying tubing net 305.On the other hand, the hot water after using turns back to heat power supply device A301 and heat power supply device B302 by returning pipe arrangement net 306.(in this embodiment 1, assuming that the consumed energy of pump 304 is much less than heat power supply device A, B.)
Fig. 4 illustrates the power characteristic that heat power supply device A301 and heat power supply device B302 has separately.Rate of load condensate x1, x2 represent that thermic load Q1, the Q2 putting on each device and the maximum heating load amount putting on each device are (also referred to as Q
mAX) ratio.Like this, if two table apparatus using power different, even if the heating load sum of two table apparatus is identical values, wastage in bulk or weight energy also can be different because of the preparation method of the output of each device.When the running of simple heat resource equipment of the impact not considering pipe arrangement net reaches best (using the connection cut-out of heat resource equipment and rate of load condensate as optimization variable), such as, when needs Q heat, by use several 7 obtain energy minimum time the combination of Q1 and Q2.Be set to the α (401) of Fig. 4 and β (403) (alpha+beta=Q).
But, when the heat radiation of pipe arrangement can not be ignored, if the heat dissipation capacity of pipe arrangement net 305,306 is Δ Q, even if then demand resident family 303 to need be Q, the heat also needing to utilize heat power supply device A301 and heat power supply device B302 to compensate Δ Q and measure, total heat demand Q
netfor Q+ Δ Q.Under these circumstances, the several automatic tracing machines being used as load become in the equipment of the optimized object of operating plan are carried out supplementary insufficient section.Here, heat power supply device B bears this effect.So the heat supply amount of heat power supply device B302 moves to β ' (404) from β (403).But observe Fig. 4 known, in this running, the power of heat power supply device B is only slightly rise.On the other hand, if utilize heat power supply device A to supplement this heat, then operation point is mobile from α (401) to α ' (402).Known in this case, because the more powerful amplitude of heat power supply device A rises, therefore compared with the situation utilizing heat power supply device B to carry out supplementing, the energy consumption sum of heat power supply device A, B reduces.Particularly, as shown in Figure 5, there is multiple demand resident family and heat resource equipment and under the type of flow is the situation not having well-determined pipe arrangement net 501 such, utilizing the type of flow to change heat dissipation capacity, in previous methods, do not occur corresponding method.
On the other hand, the feature of the control device 101 of region of the present invention heat energy supply net is, considers that it dispels the heat.By using several 9, can by stream and relative to the heat dissipation capacity in its path be included in optimization calculate in calculate, therefore, it is possible to realize considering the optimization of heat radiation.If specifically write out object function, then become the consumed energy of entire system, illustrate with several 10.Here, E

Fig. 7 illustrates application examples and the embodiment 3 of the control device 101 of region of the present invention heat energy supply net.Heat extraction source 701 is also there is, by the pipe arrangement heat supply of heat exchanger 702 to region heat energy supply net except heat power supply device A301.The mass flow flowing into heat exchanger 702 is determined by pump 703, also possesses and is used to specify which the valve 704 that utilizes heat extraction to be delivered to supplying tubing net 305 to the thermal medium accepting heat supply or to return in pipe arrangement net 306 and valve 705.
Now, the control device 101 of region heat energy supply net utilizes heat exhaust prediction section 103 to predict the rejection temperature in heat extraction source 701.Then, the hot water temperature exported with heat power supply device A301 compares, if the hot water temperature that the rejection temperature in the heat extraction source 701 of being predicted by heat exhaust prediction section 103 exports higher than heat power supply device A301, then open valve 704 and shutoff valve 705, thus to supplying tubing net 305 heat supply.Lower in the temperature of the outlet of heat exchanger 702, when cannot reach the high temperature of the hot water temperature that exports than heat power supply device A301 and reach the temperature higher than the hot water temperature returned in pipe arrangement net 306, shutoff valve 704 also opens valve 705 to carry out heat supply.In addition, when the hot water temperature returned in pipe arrangement net 306 cannot be raised, the mass flow of pump 703 is made to be 0, in the lump shutoff valve 704 and valve 705.Thus, the heat extraction dispersion in heat extraction source 701 is deposited in case, can be energy-conservation by effectively using its heat extraction to realize.
