Description

【0001】
【発明の属する技術分野】
本発明は、温水暖房システムに係わり、より詳しくは、1台の温水ボイラに異なる湯温設定の放熱器を複数併設することができる制御装置に関するものである。
【0002】
【従来の技術】
従来の種の温水暖房装置は、図5に示すようなものが知られている。(例えば、特許文献1参照)。1台の熱源機で得られた温水を主暖房用のファンコンベクタおよび副暖房用のファンコンベクタに循環し、温風をファンで室内に吹き出す温水暖房装置において、副暖房用のファンコンベクタの運転時に主暖房用のファンコンベクタが運転開始になったとき、主暖房用のファンコンベクタの主暖房制御装置31の制御信号出力手段31a が運転開始の旨を制御信号を熱源機の制御装置32に送り、この制御装置32の主暖房用制御入力手段32a がその制御信号を入力し、制御装置32の補助暖房判定手段32b が副暖房用のファンコンベクタを補助暖房用に切り替える判定を行う、制御装置32の副暖房用制御出力手段32c がその補助暖房用の連絡信号を副暖房用制御装置33に送り、この副暖房用制御装置33の制御信号入出力手段33a がファン30を低速回転に設定する。
【0003】
そしてこの発明によれば、1台の熱源機に複数の放熱機(ファンコンベクタ)を接続してなる温水暖房装置において、例えば主暖房用および副暖房用の放熱機が同時に運転状態になったときには副暖房用の放熱機のファンを低速回転として運転状態にある放熱機の能力が熱源機の能力を上回らないようにし、温水温度の低下を抑えるようにしたので、副暖房用の放熱機の能力が多少低下するものの、主暖房用の放熱機の能力を十分に発揮させることができ、主暖房用の放熱機が設置されている室内の温度を適切に保つことができ、各放熱機が設置されている室内において全て不快感を与えるということもない。
【0004】
しかし、副暖房用の放熱機に放熱量が少ない床暖房パネルを用いたい場合、ファンがないため、床暖房パネルの能力(温度)を下げることができない。
例えば、必要な温水温度が80℃程度と高いファンコンベクタと、必要な温水温度が50℃程度と低い床暖房パネルを異なる部屋で使用したい場合に、必要な温水温度が異なる放熱機をオプション(例えば、機器間の通信制御が異なる)として1台の熱源機に接続ができ、たとえ放熱機を切換えても温水温度が異なる放熱機を使用できることが望まれている。

【発明が解決しようとする課題】
本発明は上記問題点に鑑みなされたもので、1台の温水ボイラに複数の放熱器を接続してなる温水暖房システムであって、異なる湯温設定の放熱器を複数併設することができる温水暖房システムの制御装置を提供することを目的としている。
【0007】
【課題を解決するための手段】
本発明は上記課題を解決するためなされたもので、温水を生成する1台の温水ボイラと、同温水ボイラとの間で双方向または片方向通信可能に夫々接続され、前記温水ボイラから循環される温水の設定温度を可変可能に制御される複数の放熱器から構成されてなる温水暖房システムであって、
前記温水ボイラに接続される前記各放熱器への温水循環路に夫々開閉弁を設けるとともに、前記温水ボイラとの間で双方向通信可能に接続され、前記片方向通信接続側の放熱器の湯温設定温度を制御する湯温設定コントローラを設け、前記双方向通信接続側の放熱器と湯温設定コントローラとが、前記温水ボイラの制御部へ異なる湯温設定温度で運転を指示したとき、前記温水ボイラ側から各放熱器に運転優先順位を指示する信号を送信し、放熱器側からの指示により、優先を選択した前記放熱器側の前記開閉弁を開き、同時に選択されなかった方の前記開閉弁を閉じるよう制御してなる構成となっている。
【0008】
また、前記開閉弁を閉じた方の放熱器は、運転を停止するとともに運転停止の表示を行うようにしてなる構成となっている。
【0009】
また、前記各開閉弁を前記温水ボイラ内の前記温水循環路に設けてなる構成となっている。
【0010】
また、前記双方向通信接続側の放熱器が必要な温水温度が高いファンコンベクタからなり、前記片方向通信接続側の放熱器が必要な温水温度が低い床暖房パネルからなる構成となっている。
【0011】
【発明の実施の形態】
以下、本発明の実施の形態を、添付図面に基づいた実施例として説明する。
図1は本発明における温水暖房システムの制御装置を説明する構成図で、図2は本発明による制御装置のブロック図である。
図1において、本発明における温水暖房装置は、温水を生成する熱源機として利用される1台の温水ボイラ1と、主暖房用の放熱器2(本実施例ではファンコンベクタとしている)と、副暖房用の放熱器3(本実施例では床暖房パネルとしている)から構成されている。
【0012】
前記温水ボイラ1には温水を生成するボイラ4と、温水を蓄えるシスタンク5と、温水を放熱器2及び放熱器3へ循環させるポンプ6とが有り、温水ボイラ1と放熱器2及び放熱器3とはそれぞれ温水循環路としての温水の往き管7a ,7bと戻り管8a,8b で繋がれている。
【0013】前記放熱器2のファンコンベクタにはその筐体の背面上部に室内空気の吸込口2aが有り、前面下部に室内への温風の吹出口2bが有り、前記吸込口2aと吹出口2bを結ぶ空気通路に温水ボイラ1から循環する温水を熱源とする熱交換器2cと、この熱交換器2cで暖められた空気を室内へ送出する送風機2dが設けられ、温風により室内の暖房を行う。
また、前記放熱器3の床暖房パネルは蛇行状のパイプ3aに温水ボイラ1から温水を循環させて床暖房を行う。
【0014】
前記温水ボイラ1の制御装置9と前記放熱器2の制御装置10はシリアル双方向通信A1で接続され、前記温水ボイラ1から循環される温水の設定温度を可変可能に制御される。また、前記温水ボイラ1の制御装置9と前記放熱器3の制御装置11は片方向通信B1によって接続されている。
そして、前記温水ボイラ1と前記放熱器2間を接続する前記戻り管8aには第一開閉弁12a が設けられ、前記温水ボイラ1と前記放熱器3間を接続する前記戻り管8bには第二開閉弁12b が設けられている。
また、前記各開閉弁12a,12b を前記温水ボイラ1内に設けてなる構成とすることにより、制御装置9との制御配線が容易となる。
【0015】
前記放熱器3の湯温設定温度を制御する湯温設定コントローラ13を設け、同湯温設定コントローラ13と前記温水ボイラ1との間をシリアル双方向通信A2で接続するとともに、前記温水ボイラ1から循環される温水の設定温度を可変できるようになされている。
【0016】
次に上記構成において、制御動作を図1の構成図と図2のブロック図により説明する。例えば、放熱器2(ファンコンベクタ)の運転操作部10a (あるいはリモコン)の運転SWがオンになると、放熱器2の制御装置10の通信ポート10d からは制御信号が温水ボイラ1の制御装置9に送られ、これにより温水ボイラ1ではボイラ4を作動して、予め湯温設定部10b で設定された温度(例えば80℃)の温水を得ると共に、第一開閉弁12a を開き、この温水を放熱器2に循環する。放熱器2は、熱交換器2cに送られる温水が所定値を越えると、ファン2dを駆動して温風を吹き出す。
【0017】
又は、放熱器3(床暖房パネル)の運転操作部11a の運転SWがオンになると、制御装置11の通信ポート11c からは制御信号が温水ボイラ1の制御装置9に送られ、これにより温水ボイラ1ではボイラ4を作動して、予め湯温設定コントローラ13の湯温設定部13a で設定された温度(例えば50℃)の温水を得ると共に、第二開閉弁12b を開き、この温水を放熱器3のパイプ3aに循環させる。
【0018】
前記放熱器2と放熱器3の湯温設定コントローラ13が、前記温水ボイラ1の制御部9bへ異なる湯温設定温度で運転を指示したとき、前記温水ボイラ1側から前記放熱器2と湯温設定コントローラ13に運転優先順位を指示する指示伺い信号を送信する。そして、使用者側からの指示により、優先を選択した方の前記放熱器側の前記第一開閉弁12a または第二開閉弁12b を開き、同時に選択されなかった方の前記第一開閉弁12a または第二開閉弁12b を閉じると共に、この放熱器の運転を停止するよう制御する。
【0019】
次に、図3の本発明における温水ボイラの制御フローチャートおよび図4の 放熱器の制御フローチャートを参照しながら制御動作例を説明する。
まず、前記放熱器2が湯温設定a℃で運転中(ST1〜ST2)、湯温設定コントローラ13(放熱器3)が湯温設定b℃で運転開始指示(ST3〜ST4)をしたとする。もし放熱器2の運転指示がなければ湯温設定を初期化(a=0 で表示)して第一開閉弁12a を閉塞する(ST5〜ST6)。また、湯温設定コントローラ13の運転指示がなければ湯温設定を初期化(b=0 で表示)して第二開閉弁12b を閉塞する(ST7〜ST8)。湯温設定がa=bかどうかの判定を行い(ST9)、同じであれば温水ボイラを運転し放熱器2、3の両方を運転する(ST10〜ST11)。
【0020】
もし、湯温設定がa≠bの場合、温水ボイラ1はのシリアル双方向通信A1,A2 にて放熱器2および湯温設定コントローラ13に対して優先放熱器選択指示伺いの信号を送信する(ST13〜ST15)。そして、放熱器2が優先指示されれば、湯温設定コントローラ13に運転停止指示の信号が送信され、第二開閉弁12b が閉塞され、同時に第一開閉弁12a が開放されて、放熱器2が湯温設定a℃で運転される(ST16〜ST21)。
また、逆に湯温設定コントローラ13が優先指示されれば、放熱器2運転停止指示の信号が送信され、第一開閉弁12a が閉塞され、同時に第二開閉弁12b が開放されて、放熱器3が湯温設定b℃で運転される(ST23〜ST28)。
【0021】
次に、図4の放熱器の制御フローチャートを説明する。運転中、もしくは運転開始時に温水ボイラ1から送信される優先放熱器選択指示を受信した場合、そのときの運転状態を継続する。つまり放熱器2が運転中に湯温設定コントローラ13が運転開始した場合、放熱器2は運転を継続し、湯温設定コントローラ13及び放熱器3は停止を継続する。この時放熱器2、湯温設定コントローラ13ともに選択指示待ち表示を行う(ST1〜ST3)。
【0022】
そして、使用者が運転操作スイッチを押下し、湯温設定コントローラ13を選択した場合、湯温設定コントローラ13は選択指示を温水ボイラ1へ送信し、同時に運転を開始する(ST5〜ST7)。
選択されなかった放熱器2は温水ボイラ1より運転停止指示を受信し、その指示に従い他の接続放熱器が優先されたことによる停止の表示(非優先停止表示)を行い運転停止する(ST8〜ST10)。
【0023】
以上に説明したように、温水ボイラ1に接続される放熱器2、3への温水循環路に夫々開閉弁12a,12b を設けるとともに、温水ボイラ1との間で双方向通信可能に接続され、片方向通信接続側の放熱器3の湯温設定温度を制御する湯温設定コントローラ13を設け、双方向通信接続側の放熱器2と湯温設定コントローラ13とが、温水ボイラ1の制御部へ異なる湯温設定温度で運転を指示したとき、温水ボイラ1側から各放熱器2、3に運転優先順位を指示する信号を送信し、放熱器2、3側からの指示により、優先を選択した放熱器側の開閉弁を開き、同時に選択されなかった方の開閉弁を閉じるよう制御してなる構成とすることにより、異なる湯温設定の放熱器を複数併設することができる温水暖房システムの制御装置となる。
【0024】
【発明の効果】
以上説明したように、本発明によれば、1台の温水ボイラに複数の放熱器を接続してなる温水暖房システムにおいて、異なる湯温設定の放熱器を複数併設することができる温水暖房システムの制御装置となる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hot water heating system, and more particularly, to a control device capable of providing a plurality of radiators having different hot water temperatures in one hot water boiler.
[0002]
[Prior art]
As a conventional kind of hot water heating apparatus, one shown in FIG. 5 is known. (For example, see Patent Document 1). In a hot water heating system that circulates hot water obtained by one heat source unit into a fan convector for main heating and a fan convector for sub-heating, and blows warm air into the room with a fan, the fan convector for sub-heating is operated. When the main heating fan convector starts operation, the control signal output means 31a of the main heating control device 31 for the main heating fan convector sends a control signal to the effect that the operation has started to the control device 32 of the heat source unit, The main heating control input means 32a of the control device 32 receives the control signal, and the auxiliary heating determination means 32b of the control device 32 determines whether to switch the sub-heating fan convector to the auxiliary heating. The sub-heating control output means 32c sends the auxiliary heating communication signal to the sub-heating control device 33, and the control signal input / output means of the sub-heating control device 33 33a sets the fan 30 to low speed rotation.
[0003]
According to the present invention, in a hot water heating apparatus in which a plurality of radiators (fan convectors) are connected to one heat source device, for example, when the radiators for the main heating and the sub-heating are simultaneously operated. Since the fan of the sub-heating radiator is running at low speed so that the capacity of the radiator in operation does not exceed the capability of the heat source unit and suppress the decrease in hot water temperature, the capacity of the sub-heating radiator Despite a slight decrease, the ability of the main heating radiator can be fully demonstrated, the temperature in the room where the main heating radiator is installed can be maintained properly, and each radiator is installed It does not give any discomfort in the room.
[0004]
However, when it is desired to use a floor heating panel with a small amount of heat radiation for the sub-heating radiator, the capacity (temperature) of the floor heating panel cannot be reduced because there is no fan.
For example, when a fan convector whose required hot water temperature is as high as about 80 ° C. and a floor heating panel whose necessary hot water temperature is as low as about 50 ° C. are required to be used in different rooms, a radiator having a different required hot water temperature is optional (for example, It is desired that a radiator having a different hot water temperature can be used even if the radiator is switched even if the radiator is switched.

Hereinafter, embodiments of the present invention will be described as examples based on the accompanying drawings.
FIG. 1 is a configuration diagram illustrating a control device of a hot water heating system according to the present invention, and FIG. 2 is a block diagram of a control device according to the present invention.
In FIG. 1, the hot water heating apparatus according to the present invention includes one hot water boiler 1 used as a heat source device for generating hot water, a radiator 2 for main heating (in the present embodiment, a fan convector), It is composed of a radiator 3 for heating (in this embodiment, a floor heating panel).
[0012]
The hot water boiler 1 includes a boiler 4 that generates hot water, a cis tank 5 that stores hot water, and a pump 6 that circulates hot water to the radiator 2 and the radiator 3. The hot water boiler 1, the radiator 2, and the radiator 3 Are connected to hot water outgoing pipes 7a and 7b as hot water circulation paths and return pipes 8a and 8b, respectively.

The control device 9 of the hot water boiler 1 and the control device 11 of the radiator 3 are connected by one-way communication B1.
The return pipe 8a connecting the hot water boiler 1 and the radiator 2 is provided with a first opening / closing valve 12a, and the return pipe 8b connecting the hot water boiler 1 and the radiator 3 is provided with a first open / close valve. A two-way valve 12b is provided.
Further, by providing the on-off valves 12a and 12b in the hot water boiler 1, control wiring to the control device 9 is facilitated.
[0015]
A hot water temperature setting controller 13 for controlling the hot water temperature setting temperature of the radiator 3 is provided. The hot water temperature setting controller 13 is connected to the hot water boiler 1 by serial two-way communication A2. The set temperature of the circulated hot water can be varied.
[0016]
Next, the control operation in the above configuration will be described with reference to the configuration diagram of FIG. 1 and the block diagram of FIG. For example, when the operation switch of the operation unit 10a (or the remote controller) of the radiator 2 (fan convector) is turned on, a control signal is transmitted from the communication port 10d of the control device 10 of the radiator 2 to the control device 9 of the hot water boiler 1. Then, the hot water boiler 1 operates the boiler 4 to obtain hot water of a temperature (for example, 80 ° C.) set in advance by the hot water temperature setting unit 10b, and opens the first opening / closing valve 12a to release the hot water. Circulation to vessel 2. When the hot water sent to the heat exchanger 2c exceeds a predetermined value, the radiator 2 drives the fan 2d to blow hot air.
[0017]
Alternatively, when the operation switch of the operation operation unit 11a of the radiator 3 (floor heating panel) is turned on, a control signal is sent from the communication port 11c of the control device 11 to the control device 9 of the hot water boiler 1, whereby the hot water boiler is In 1, the boiler 4 is operated to obtain hot water of a temperature (for example, 50 ° C.) set in advance by the hot water setting unit 13 a of the hot water setting controller 13, and the second on-off valve 12 b is opened, and this hot water is radiated by the radiator. 3 is circulated through the pipe 3a.
[0018]
When the hot water temperature setting controller 13 of the radiator 2 and the radiator 3 instructs the control unit 9b of the hot water boiler 1 to operate at a different hot water temperature setting temperature, the radiator 2 and the hot water temperature from the hot water boiler 1 side. An instruction inquiry signal instructing the operation priority is transmitted to the setting controller 13. Then, in accordance with an instruction from the user side, the first on-off valve 12a or the second on-off valve 12b on the radiator side on which the priority has been selected is opened, and the first on-off valve 12a or the one not selected at the same time is opened. The control is performed so as to close the second on-off valve 12b and stop the operation of the radiator.
[0019]
Next, an example of the control operation will be described with reference to the control flowchart of the hot water boiler of the present invention in FIG. 3 and the control flowchart of the radiator in FIG.
First, while the radiator 2 is operating at the hot water temperature setting a ° C. (ST1 to ST2), the hot water temperature setting controller 13 (radiator 3) issues an operation start instruction (ST3 to ST4) at the hot water temperature setting b ° C. . If there is no operation instruction of the radiator 2, the hot water temperature setting is initialized (indicated by a = 0) and the first on-off valve 12a is closed (ST5 to ST6). If there is no operation instruction from the hot water temperature setting controller 13, the hot water temperature setting is initialized (indicated by b = 0) and the second on-off valve 12b is closed (ST7 to ST8). It is determined whether or not the hot water temperature setting is a = b (ST9), and if they are the same, the hot water boiler is operated and both the radiators 2 and 3 are operated (ST10 to ST11).
[0020]
If the hot water temperature setting is a ≠ b, the hot water boiler 1 transmits a priority radiator selection instruction inquiry signal to the radiator 2 and the hot water temperature setting controller 13 through the serial two-way communication A1 and A2 ( ST13 to ST15). When the radiator 2 is given a priority instruction, an operation stop instruction signal is transmitted to the hot water temperature setting controller 13, the second on-off valve 12b is closed, and at the same time, the first on-off valve 12a is opened. Is operated at the hot water temperature setting a ° C. (ST16 to ST21).
Conversely, if the hot water temperature setting controller 13 is given a priority instruction, a signal of an instruction to stop the operation of the radiator 2 is transmitted, the first on-off valve 12a is closed, and at the same time, the second on-off valve 12b is opened. 3 is operated at the hot water temperature setting b ° C. (ST23 to ST28).
[0021]
Next, a control flowchart of the radiator in FIG. 4 will be described. If a priority radiator selection instruction transmitted from the hot water boiler 1 is received during operation or at the start of operation, the operation state at that time is continued. That is, when the hot water temperature setting controller 13 starts operating while the radiator 2 is operating, the radiator 2 continues to operate, and the hot water temperature setting controller 13 and the radiator 3 continue to stop. At this time, both the radiator 2 and the hot water temperature setting controller 13 perform a selection instruction waiting display (ST1 to ST3).
[0022]
Then, when the user presses the operation switch and selects the hot water temperature setting controller 13, the hot water temperature setting controller 13 transmits a selection instruction to the hot water boiler 1 and starts operation at the same time (ST5 to ST7).
The radiator 2 that is not selected receives the operation stop instruction from the hot water boiler 1 and displays a stop (non-priority stop display) due to the prioritization of another connected radiator according to the instruction, and stops the operation (ST8 to ST8). ST10).
[0023]
As described above, the hot water circulation paths to the radiators 2 and 3 connected to the hot water boiler 1 are provided with the open / close valves 12a and 12b, respectively, and are connected to the hot water boiler 1 so as to be capable of bidirectional communication.
