Japanese Patent No. 4063756

In the heating system described in Patent Document 1 shown in FIG. 17, the heating heat medium may be returned to the heat source machine 130 after radiating heat from the first heating radiator 114 laid in the center of the first room 110. However, since the heating load of the first room 110 is smaller than that of the previous house in a high airtight and highly insulated house in recent years, the temperature of the heating medium when the heating medium returns to the heat source unit 130 after radiating heat. Tend to be higher. As a result, the temperature rise of the heating heat medium due to the heating of the heat source unit 130 and the output of the heat source unit 130 are reduced, and the heating operation efficiency of the heat source unit 130 tends to be reduced.
Moreover, when the temperature after heat radiation of the heating medium becomes higher than the conventional temperature, efficient heating can be used by heating another room with the retained heat. Does not go.

It is limited at the time of circulation of the heating heat medium to the radiator 114. In this case, the heating of the second room 120 can be performed only when the first room 110 is being heated, and the request of the user who desires the independent heating of the second room 120 cannot be met. In the configuration shown in FIG. 18, when the outside air temperature is remarkably lowered and the heating load of the first room 110 and the second room 120 becomes very large, the temperature of the heating heat medium after the heating of the first room 110 becomes high.

The heating system 1B of the second embodiment shown in FIG. 2 is different from the heating system 1A of the first embodiment shown in FIG. 1 in that a second heating circulation pump 42 is added. Hereinafter, this difference will be mainly described.

  The second heating circulation pump 42 is provided at any position of the post-heating heating pipe 35 or the post-heating heat radiation pipe 36. The second heating circulation pump 42 is driven based on a control signal from the heat source unit control means 31, and the heating heat medium is caused to flow into the heat source unit 30 from the post-heat radiation pipe 36 and is heated by the combustion heat exchanger 33. The heating heat medium is driven to circulate so that the heating heat medium is discharged from the pipe 35 after heating and to supplement the circulation of the heating heat medium by the first heating circulation pump 41.

For example, the heat source unit control means 31 has a relatively small amount of heat radiation and a relatively small circulation flow rate of the heating heat medium when heating only the first room or heating only the second room. Only the first heating circulation pump 41 is driven.
Further, the heat source device control means 31 has a relatively large heat radiation amount when the first room and the second room are heated in parallel or when the first room and the second room are heated in series. Therefore, both the first heating circulation pump 41 and the second heating circulation pump 42 are driven.

  For example, in a case where an existing heating system for heating only the first room is installed and a heating system as shown in FIG. 2 is added later, the existing first heating circulation pump has a capacity. Even if it is a shortage, the capability of the 1st heating circulation pump can be supplemented by replacing the 1st heating circulation pump by adding the 2nd heating circulation pump.

Moreover, the 3rd heating circulation pump 43 is driven based on the control signal from the heat-source-equipment control means 31, and when it is driven, at least a part of the heating heat medium from the heating / heat radiation post-pipe 36 is supplied to the post-heating / heating pipe 35. It is possible to lead to. Note that when the third heating circulation pump 43 is stopped, the heating heat medium does not flow into the second heating bypass pipe 62.

  For example, the heat source unit control means 31 has a relatively small amount of heat radiation and a relatively small circulation flow rate of the heating heat medium when heating only the first room or heating only the second room. Only the first heating circulation pump 41 is driven. Further, the heat source device control means 31 has a relatively large heat radiation amount when the first room and the second room are heated in parallel or when the first room and the second room are heated in series. Therefore, both the first heating circulation pump 41 and the third heating circulation pump 43 are driven.

  For example, in a case where an existing heating system for heating only the first room is installed and a heating system as shown in FIG. 3 is added later, the existing first heating circulation pump has a capacity. Even if it is insufficient, by adding the second heating bypass pipe and the third heating circulation pump, the capacity of the first heating circulation pump can be supplemented without replacing the first heating circulation pump.
