特許第4063756号公報Japanese Patent No. 4063756

図13に示す特許文献1に記載された暖房システムでは、暖房熱媒は第1部屋110の中央部に敷設された第1暖房放熱体114にて放熱した後で熱源機130に戻される場合が有るが、近年の高気密高断熱住宅では、それ以前の住宅と比較して第1部屋110の暖房負荷が小さくなるため、暖房熱媒が放熱後に熱源機130に戻る際の暖房熱媒の温度が高くなる傾向にある。この結果、熱源機130の加熱による暖房熱媒の温度上昇及び熱源機130の出力が小さくなり、熱源機130の暖房運転効率が低下する傾向にある。
また、部屋の中央部を暖房する第1暖房放熱体114は、すでに数種類の製品が実用化されているが、部屋の周辺部を暖房する第2暖房放熱体124は、新たな専用品として設計する必要があるので、開発期間と手間がかかる。
また近年では、リビングとダイニングを1つの部屋としている場合があり、このような場合は、部屋の中央部を暖房するために設計された暖房放熱体を2つ用意して、リビングのエリアと、ダイニングのエリアとを、それぞれ暖房できるようにすると、効率的な暖房を行うことが期待できる。
しかし、図13に示す特許文献1の構成において、例えば第1暖房放熱体114をリビングに配置し、第2暖房放熱体124をダイニングに配置すると、ダイニングのみを暖房することができない。この場合では、ダイニングの暖房は、リビングを暖房している場合にしか行うことができず、ダイニングの単独暖房を所望する利用者の要求に応えることができない。
また、図13に示す特許文献1の構成では、第1暖房放熱体114と第2暖房放熱体124を並列に暖房運転することができないので、外気温度が著しく低下して第1部屋110の暖房負荷が非常に大きくなった場合、第1暖房放熱体114と第2暖房放熱体124を直列に暖房運転(第1暖房放熱体に先に暖房熱媒を流通)した際、第2暖房放熱体での暖房を充分に行うことができない可能性がある。
本発明は、このような点に鑑みて創案されたものであり、1つの部屋に設けた第1暖房放熱体と第2暖房放熱体とを用いて、より快適に、且つより効率良く暖房することが可能であり、熱源機の暖房運転効率をより向上させることができる暖房システムを提供することを課題とする。
In the heating system described in Patent Document 1 shown in FIG. 13, 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.
In addition, several types of products have already been put to practical use for the first heating radiator 114 for heating the central portion of the room, but the second heating radiator 124 for heating the peripheral portion of the room is designed as a new dedicated product. It takes time and effort to develop.
In recent years, there are cases where the living room and the dining room are in one room. In such a case, two heating radiators designed to heat the central part of the room are prepared, the living area, Efficient heating can be expected if the dining area can be heated.
However, in the configuration of Patent Document 1 shown in FIG. 13, for example, if the first heating radiator 114 is arranged in the living room and the second heating radiator 124 is arranged in the dining room, only the dining room cannot be heated. In this case, heating of the dining room can be performed only when the living room is heated, and it is impossible to meet the demand of a user who desires independent heating of the dining room.
In addition, in the configuration of Patent Document 1 shown in FIG. 13, the first heating radiator 114 and the second heating radiator 124 cannot be heated in parallel. When the load becomes very large, when the first heating radiator 114 and the second heating radiator 124 are heated in series (the heating medium is first circulated through the first heating radiator), the second heating radiator There is a possibility that heating in the room cannot be performed sufficiently.
The present invention has been devised in view of such a point, and uses the first heating radiator and the second heating radiator provided in one room to perform heating more comfortably and more efficiently. It is possible to provide a heating system that can further improve the heating operation efficiency of the heat source machine.

For example, the user operates the operation state setting means 11 to input the start of the heating operation of only the first heating radiator 14 and the heating level (strong, medium, weak, heating temperature, etc.). In this case, there is no request for the heating operation of the second heating radiator 24.

In this case, there is no request for heating operation of the first heating radiator 14.

For example, the heat source unit control means 31 recognizes the heating start request and the heating level of the second heating radiator 24, activates the heat source unit 30 to heat the heating heat medium, and activates the first heating circulation pump 41. Then, circulation of the heating heat medium is started, the first opening / closing valve 12 is controlled to be closed, the second opening / closing valve 22 is controlled to be opened, and the second flow path switching valve 26 is connected to the second heating / radiating mixed pipe. The heating heat medium flowing in from 25 is controlled to be discharged toward the heating pipe mixing means 46.

It controls to the side discharged toward the heating pipe mixing means 46.

The heating heat medium flowing in from the second heating / radiating mixed pipe 25 is controlled to be discharged toward the heating pipe mixing means 46.
For example, the heat source unit control means 31 performs parallel heating for a second predetermined time (for example, about 1 hour) after starting the parallel heating operation of the first heating radiator 14 and the second heating radiator 24 as described above. After the operation is maintained and the second predetermined time has elapsed, the following (4) first series heating operation and (5) second series heating operation are performed every first predetermined time (for example, about 10 minutes). Alternatively, the heating operation may be performed while alternately switching to each other.

And after the 2nd predetermined time passes, the heat-source equipment control means 31 performs the 1st series heating operation of (4) mentioned later and the 2nd series heating operation of (5) 1st from parallel heating operation. By performing the heating operation while alternately switching every predetermined time, it is possible to maintain heating more efficiently and to perform heating by the first heating radiator 14 and the second heating radiator 24 more uniformly.

例えば上記の「(4)熱源機に対して、第1暖房放熱体14と第2暖房放熱体24を直列に接続した暖房運転であって、先に第1暖房放熱体14に暖房熱媒を流通させる暖房運転(第1直列暖房運転)。」を開始してから第1所定時間が経過後、第1所定時間の間、下記の第2直列暖房運転を行い、第2直列暖房運転を開始してから第1所定時間が経過後は、「(4)熱源機に対して、第1暖房放熱体14と第2暖房放熱体24を直列に接続した暖房運転であって、先に第1暖房放熱体14に暖房熱媒を流通させる暖房運転(第1直列暖房運転)。」に切り替え、第1所定時間毎に第1直列暖房運転と第2直列暖房運転とを交互に切り替えて暖房する。
第2直列暖房運転では、熱源機制御手段31は、第1開閉弁12を閉状態に制御し、第2開閉弁22を開状態に制御し、第1流路切替弁16を、第1暖房放熱後混合配管15から流入された暖房熱媒を暖房配管混合手段46に向けて吐出する側に制御し、第2流路切替弁26を、第2暖房放熱後混合配管25から流入された暖房熱媒を第2暖房バイパス配管62に向けて吐出する側へと制御する。

●[第2の実施の形態の暖房システム1B(図2)]
次に図2を用いて、第2の実施の形態の暖房システム1Bについて説明する。図2に示す第2の実施の形態の暖房システム1Bは、図1に示す第1の実施の形態の暖房システム1Aに対して、第2暖房循環ポンプ42が追加されている点が異なる。以下、この相違点について主に説明する。
● [Heating system 1B of the second embodiment (FIG. 2)]
Next, the heating system 1B of 2nd Embodiment is demonstrated using FIG. 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.

第2暖房循環ポンプ42は、暖房加熱後配管35あるいは暖房放熱後配管36のいずれかの位置に設けられている。また第2暖房循環ポンプ42は、熱源機制御手段31からの制御信号に基づいて駆動され、暖房放熱後配管36から暖房熱媒を熱源機30に流入させ、燃焼熱交換器33にて加熱した暖房熱媒を暖房加熱後配管35から吐出するように、暖房熱媒を循環させ、第1暖房循環ポンプ41による暖房熱媒の循環を補うように駆動される。   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.

例えば、熱源機制御手段31は、第1暖房放熱体14のみを暖房運転する場合や、第2暖房放熱体24のみを暖房運転する場合では、放熱量が比較的少なく、暖房熱媒の循環流量が比較的少ないので、第1暖房循環ポンプ41のみを駆動する。
また熱源機制御手段31は、第1暖房放熱体14と第2暖房放熱体24を並列に暖房運転する場合や、第1暖房放熱体14と第2暖房放熱体24を直列に暖房運転する場合では、放熱量が比較的多く、暖房熱媒の循環流量が比較的多いので、第1暖房循環ポンプ41と第2暖房循環ポンプ42の双方を駆動する。
For example, in the case where only the first heating radiator 14 is heating-operated or the second heating radiator 24 is only heating-operated, the heat source controller 31 has a relatively small amount of heat radiation, and the circulation flow rate of the heating heat medium Therefore, only the first heating circulation pump 41 is driven.
Moreover, the heat source machine control means 31 is a case where the first heating radiator 14 and the second heating radiator 24 are heated in parallel, or the first heating radiator 14 and the second heating radiator 24 are heated in series. Then, since the heat radiation amount is relatively large and the circulation flow rate of the heating heat medium is relatively large, both the first heating circulation pump 41 and the second heating circulation pump 42 are driven.

例えば、第1暖房放熱体14のみが敷設された既存の暖房システムが設置されていた住宅に、あとから追加工事を行って図2に示すような暖房システムとした場合(第2暖房放熱体24等を追加した場合)、既存の第1暖房循環ポンプ41では能力が不足するような場合であっても、第2暖房循環ポンプ42を追加することで、第1暖房循環ポンプ41を交換することなく第1暖房循環ポンプ41の能力を補うことができる。   For example, in a case where an existing heating system in which only the first heating radiator 14 is laid is installed, additional construction is performed later to obtain a heating system as shown in FIG. 2 (second heating radiator 24). Even if the capacity of the existing first heating circulation pump 41 is insufficient, the first heating circulation pump 41 can be replaced by adding the second heating circulation pump 42. The capacity of the first heating circulation pump 41 can be supplemented.

●[第3の実施の形態の暖房システム1C(図3)]
次に図3を用いて、第3の実施の形態の暖房システム1Cについて説明する。図3に示す第3の実施の形態の暖房システム1Cは、図1に示す第1の実施の形態の暖房システム1Aに対して、第3暖房バイパス配管63と第3暖房循環ポンプ43が追加されている点が異なる。以下、この相違点について主に説明する。
● [Heating system 1C of the third embodiment (FIG. 3)]
Next, a heating system 1C according to a third embodiment will be described with reference to FIG. A heating system 1C according to the third embodiment shown in FIG. 3 has a third heating bypass pipe 63 and a third heating circulation pump 43 added to the heating system 1A according to the first embodiment shown in FIG. Is different. Hereinafter, this difference will be mainly described.

第3暖房バイパス配管63は、暖房放熱後配管36のいずれかの位置と、暖房加熱後配管35のいずれかの位置と、に接続されている。
第3暖房循環ポンプ43は、第3暖房バイパス配管63のいずれかの位置に設けられている。また第3暖房循環ポンプ43は、熱源機制御手段31からの制御信号に基づいて駆動され、駆動された場合は、暖房放熱後配管36からの暖房熱媒の少なくとも一部を暖房加熱後配管35に導くことが可能である。なお、第3暖房循環ポンプ43が停止している場合、暖房熱媒は第3暖房バイパス配管63に流入することはない。
The third heating bypass pipe 63 is connected to any position of the post-heating heat radiation pipe 36 and any position of the post-heating heating pipe 35.
The third heating circulation pump 43 is provided at any position of the third heating bypass pipe 63. 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 third heating bypass pipe 63.

例えば、熱源機制御手段31は、第1暖房放熱体14のみを暖房運転する場合や、第2暖房放熱体24のみを暖房運転する場合では、放熱量が比較的少なく、暖房熱媒の循環流量が比較的少ないので、第1暖房循環ポンプ41のみを駆動する。また熱源機制御手段31は、第1暖房放熱体14と第2暖房放熱体24を並列に暖房運転する場合や、第1暖房放熱体14と第2暖房放熱体24を直列に暖房運転する場合では、放熱量が比較的多く、暖房熱媒の循環流量が比較的多いので、第1暖房循環ポンプ41と第3暖房循環ポンプ43の双方を駆動する。   For example, in the case where only the first heating radiator 14 is heating-operated or the second heating radiator 24 is only heating-operated, the heat source controller 31 has a relatively small amount of heat radiation, and the circulation flow rate of the heating heat medium Therefore, only the first heating circulation pump 41 is driven. Moreover, the heat source machine control means 31 is a case where the first heating radiator 14 and the second heating radiator 24 are heated in parallel, or the first heating radiator 14 and the second heating radiator 24 are heated in series. Then, since the heat radiation amount is relatively large and the circulation flow rate of the heating heat medium is relatively large, both the first heating circulation pump 41 and the third heating circulation pump 43 are driven.

例えば、第1暖房放熱体14のみが敷設された既存の暖房システムが設置されていた住宅に、あとから追加工事を行って図3に示すような暖房システムとした場合(第2暖房放熱体24等を追加した場合)、既存の第1暖房循環ポンプ41では能力が不足するような場合であっても、第3暖房バイパス配管63と第3暖房循環ポンプ43を追加することで、第1暖房循環ポンプ41を交換することなく第1暖房循環ポンプ41の能力を補うことができる。   For example, in a case where an existing heating system in which only the first heating radiator 14 is laid is installed, additional construction is performed later to obtain a heating system as shown in FIG. 3 (second heating radiator 24). Etc.), even if the capacity of the existing first heating circulation pump 41 is insufficient, by adding the third heating bypass pipe 63 and the third heating circulation pump 43, the first heating circulation pump 41 The capacity of the first heating circulation pump 41 can be supplemented without replacing the circulation pump 41.
