Description

【0001】
【発明の属する技術分野】
本発明は、床暖房器、空気調和機及び浴室暖房機等の温水式の放熱器に温水を供給して暖房する温水式床暖房システムに関するものである。
【0002】
【従来技術】
一般に従来の温水式床暖房システム(以下、単に床暖房システムという)は、例えば、室外等に設置された熱源機と、居室等に設置された床暖房器や空気調和機等の放熱器とを温水配管で接続し、熱源機で生成された温水を放熱器へ循環供給して居室等を暖房するものである。
【0003】
この種の床暖房システムは、熱源機と放熱器をつなぐ温水配管に開閉弁を設け、この開閉弁を周期的に開閉制御することにより暖房能力を制御している。
【0004】
また、熱源機には生成する温水温度を複数の温度(例えば65℃、70℃または75℃)に設定できるものもあり、放熱器等から要求される温水温度に応じていずれか1つの温度(例えば、70℃)の温水を生成する。
【0005】
【発明が解決しようとする課題】
ところで、1台の熱源機に床暖房器や空気調和機等、複数系統の放熱器が接続されている場合、それぞれの放熱器から要求される温水温度が異なることがある。この場合、熱源機ではいずれか1つの温水温度を選択して温水を生成することになる(要求温水温度の高いものを選択するようになっているので、使用温水温度の高い空気調和機からの要求温水温度に設定される)。そのため、床暖房器に要求した温度の温水が供給されないことがある。一方、床暖房器は、床暖房器の要求した温水温度による開閉弁の制御を行うため室温調節が正常に行われないという問題があった。
【0006】
特に、季節の変わり目など暖房負荷が小さいときの暖まりすぎや、真冬の暖房負荷が大きいときの立ち上がりの遅れ等があった。
【0007】
本発明は、上述のような従来の問題点に鑑みなされたものであり、温水を複数の温度に生成可能な熱源機と、この熱源機から温水を供給される床暖房器とを備え、この床暖房器の温度調節を適切に行うことのできる温水式床暖房システムを提供することを目的とする。
【0008】
【課題を解決するための手段】
上記目的を達成するために、請求項1に記載の発明は、複数温度の温水を生成可能な熱源機と、この熱源機で生成される温水温度を要求する操作手段と、前記熱源機で生成される温水を開閉弁を介して供給し暖房する床暖房器と、室温を検出する室温センサとを備えた温水式床暖房システムにおいて、前記室温センサで検出される温度と室温設定温度の偏差、ならびに要求する温水温度に基づいて前記開閉弁の一定周期毎の開閉比率を制御することを特徴とする。
【0009】
請求項2に記載の発明は、請求項1に記載の温水式床暖房システムにおいて、前記熱源機で生成される温水温度を検出する温水センサを備え、この温水センサで検出される温水温度と前記操作手段により要求する温水温度とが異なる場合、検出される温水温度と要求する温水温度との差、ならびに室温センサで検出される温度と室温設定温度の偏差に基づいて前記開閉弁の一定周期毎の開閉比率を制御することを特徴とする。
【0010】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。図1は本発明の一実施形態における床暖房システムの概略説明図、図2は床暖房システムを操作するリモコンの正面図である。
【0011】
図1において、本床暖房システム1は、室外に設置した熱源機2と、室内に敷設した床暖房器3と、室内の壁等に設置した空気調和機4と、床暖房器用リモコンRと、空気調和機用リモコンMとを備えている。
【0012】
前記熱源機2内には、下方にガス燃焼部5aを配設した燃焼装置5と、この燃焼装置5の外周に巻き付けられたパイプ状熱交換器6とを有し、この熱交換器6が配水配管7にて床暖房器3に接続されている。前記温水配管7の途中には、電磁弁よりなる開閉弁8と循環ポンプPとを設け、開閉弁8、循環ポンプP、室温センサ9、温水センサ10及びガス燃焼部4のガス弁12等を制御装置13に接続し、全体として床暖房システム1を構成している。室温センサ9はリモコンR付近の室温を検出し、温水センサ10は熱交換器6の出口部に設けられ温水温度を検出しそれぞれ制御装置13に温度信号を送信している。なお、空気調和機4には図示しない開閉弁、室温センサ及び制御装置等を備えている。
【0013】
図2において、リモコンRには、運転入/切スイッチ14、希望する床温度を設定する室温設定スイッチ16、希望する時刻に運転・停止を行わせるタイマースイッチ17、及び熱源機2に対して温水温度を要求する温水温度要求スイッチ18等の操作スイッチを有し、さらにこれらの操作スイッチで設定された内容や室温等を液晶表示する表示部22及び前記室温センサ9を有している。
【0014】
前記運転入/切スイッチ14は、一度このスイッチ14を押すことにより床暖房器3の運転が開始され、もう一度押すことにより運転が停止される。室温設定スイッチ16は上がるスイッチ16aと下がるスイッチ16bを有し表示部22に表示される設定温度を希望する室温に設定する。温水温度要求スイッチ18は、熱源機2で生成する温水温度(温水センサ10で検出される温度)を、例えば、65℃、70℃または75℃に設定するよう要求することができる。
【0015】
図3において、前記制御装置13は、制御用プログラムを格納したROM、各種データを記憶するRAM、アナログ/ディジタル変換を行うA/D変換器、随時書き込み可能な記憶手段としてEEPROM等を内蔵し、床暖房機全体の制御を行うマイクロコンピュータ(以下マイコンという)23を有している。
【0016】
前記マイコン23の入力側には、室温センサ9や運転入/切スイッチ14、設定温度スイッチ15、タイマースイッチ17、温水温度要求スイッチ18等が接続されている。
【0017】
一方、マイコン23の出力側には、循環ポンプP、ガス弁12、開閉弁8、リモコンRの表示部22等が接続されている。
【0018】
次にこの床暖房システムの運転時の動作を説明する。
【0019】
図1において、床暖房器用のリモコンRの運転入/切スイッチ14が操作され運転が開始されると、制御装置13は、燃焼装置5の燃焼によりパイプ状熱交換器3内の水を加熱する。このときの温水温度は床暖房器3または空気調和機4で設定操作された要求温度から選択される(空気調和機4で要求した温水温度を優先して選択する)。加熱された温水は、循環ポンプPの作動により温水配管7を経て床暖房器3に流入し、この床暖房器3を暖めるとともに輻射熱によって室内を加温して室温を上昇させる。制御装置13は、室温と設定温度の偏差に基づいて開閉弁8を制御し安定した床温を保つようにする。
【0020】
前記開閉弁8は、図4に示すように、一定周期毎に開閉比率を設定して開閉制御される。例えば一周期Tを20分とし、開閉弁8の開放時間t1を15分とすることで暖房能力を大きく、開放時間t2を5分とすることで暖房能力を小さくしている。
【0021】
次に室温と設定温度の偏差、床暖房器の要求温水温度、並びに熱源機で生成される温水温度に対して、開閉弁の開閉制御について説明する。
【0022】
図5は、床暖房器の要求温水温度65℃で、熱源機で生成される温水温度が65℃、70℃及び75℃のときにおける開閉弁の開閉制御を示す表である。
【0023】
要求温水温度、生成される温水温度ともに65℃の場合、室温と設定温度との偏差が2℃以上のとき、開閉弁8のON/OFF時間は、それぞれ2分/18分である。同様に1.5℃以上2.0℃未満のとき4分/16分、1.0℃以上1.5℃未満のとき6分/14分、0.5℃以上1.0℃未満のとき8分/12分、0℃以上0.5℃未満のとき10分/10分、−0.5℃以上0℃未満のとき12分/8分、−1.0℃以上−0.5℃未満のとき14分/6分、−1.5℃以上1.0℃未満のとき16分/4分、−2.0℃以上−1.5℃未満のとき18分/2分、−2.0℃未満のとき20分/0分である。このように室温と設定温度の偏差に応じて開閉弁のON/OFF時間を設定するので、床暖房器3の暖房能力を自動的に調節して適切な床暖房を実施できる。
【0024】
また、床暖房器3の要求温水温度が65℃、生成される温水温度が70℃の場合、前述の要求温水温度、生成温水温度ともに65℃の場合に比べ、開閉弁のON時間を、少し短く設定する。同様に、床暖房器の要求温水温度が65℃、生成される温水温度が75℃の場合、さらに開閉弁8のON時間を短く設定する。このように開閉弁8のON/OFF時間を、要求温水温度と実際の温水温度を比較して設定することにより、要求温水温度と生成される温水温度が異なっていても適切な床暖房運転を実施することができる。
【0025】
図6は床暖房器の要求温水温度70℃で、生成される温水温度が65℃、70℃及び75℃のときにおける開閉弁の開閉制御を示す表である。
【0026】
要求温水温度が70℃、生成される温水温度が70℃の場合、開閉弁8のON/OFF時間を、前述した要求温水温度、生成温水温度がともに65℃の場合と同様のON/OFF時間に設定している。そして、生成される温水温度が要求温度より低い65℃のときには、ON時間を長く、生成される温水温度が要求温度より高い75℃のときには、ON時間を短く制御することにより、適切な床暖房運転をすることができる。
【0027】
図7は床暖房器の要求温水温度75℃で、生成される温水温度が65℃、70℃及び75℃のときにおける開閉弁の開閉制御を示す表である。
【0028】
要求温水温度、生成温水温度ともに75℃の場合、開閉弁のON/OFF時間を、図5における要求温水温度65℃、生成温水温度65℃のときとほぼ同様の制御を行う。そして、生成される温水温度が要求温度より低い70℃のときには、ON時間を長く、さらに低い65℃のときには、さらにON時間を短くすることにより、適切な床暖房運転をすることができる。
【0029】
以上説明したように、本実施形態では、床暖房器3で要求した温水温度と熱源機2で生成する温水温度とが異なっていても、制御装置23が要求温水温度と検出される温水温度の温度差、ならびに室温と設定温度の偏差に基づいて開閉弁8のON/OFF時間を制御するので、適切な床暖房運転をすることができ、快適な床暖房を実現することができる。
【0030】
そして、運転開始時や室温が急激に低下したときなど暖房負荷が大きいときには、開閉弁8のON時間を長くして立ち上がり時間を短くし、季節の変わり目や他に暖房装置を併用する場合など暖房負荷が小さいときにはON時間を短くして暖めすぎをなくすことができる。
【0031】
以上、一実施形態に基づいて本発明を説明したが、本発明は、上記実施形態に限定されるものではない。
【0032】
本実施形態では、床暖房機3の開閉弁8の制御を温水センサ10の検出値に基づいて行っているが、床暖房器3のみ運転する場合には床暖房器3の要求温水温度、床暖房器3と空気調和機4の両方を運転する場合には空気調和機4の要求温水温度に基づいて行うようにしても良い。
【0033】
【発明の効果】
以上説明したように、本発明の床暖房システムは、複数温度の温水が生成可能な熱源機と、熱源機で生成される温水を開閉弁を介して供給する床暖房器とを備え、床暖房器に供給される温水温度に基づいて開閉弁の開閉比率を制御するので、要求以外の温水温度で温水が生成された場合でも、床暖房器が適切な床暖房を行うことができ、快適な床暖房を実現できる。
【0034】
また、床暖房器は、室温と設定温度の偏差、並びに要求温水温度と供給される温水温度の差に基づいて開閉弁の開閉比率を制御しているので、暖房負荷が大きいときの立ち上がりの遅れや、暖房負荷が小さいときの暖まりすぎを防いで快適な床暖房を実現できる。

The room temperature sensor 9 detects a room temperature near the remote controller R, and the hot water sensor 10 is provided at the outlet of the heat exchanger 6 to detect the temperature of the hot water and transmit a temperature signal to the control device 13 respectively. The air conditioner 4 includes an open / close valve, a room temperature sensor, a control device, and the like (not shown).
[0013]
In FIG. 2, the remote control R includes an operation on / off switch 14, a room temperature setting switch 16 for setting a desired floor temperature, a timer switch 17 for performing operation / stop at a desired time, and hot water for the heat source unit 2. It has operation switches such as a hot water temperature request switch 18 for requesting a temperature, and further has a display unit 22 for displaying the contents set by these operation switches and room temperature on a liquid crystal display, and the room temperature sensor 9.
[0014]
The operation on / off switch 14 starts the operation of the floor heater 3 by pressing the switch 14 once, and stops operation by pressing the switch 14 again. The room temperature setting switch 16 has an up switch 16a and a down switch 16b, and sets the set temperature displayed on the display unit 22 to a desired room temperature. The hot water temperature request switch 18 can request that the hot water temperature generated by the heat source device 2 (the temperature detected by the hot water sensor 10) be set to, for example, 65 ° C., 70 ° C., or 75 ° C.

[0018]
Next, the operation of the floor heating system during operation will be described.
[0019]
In FIG. 1, when the operation on / off switch 14 of the remote control R for the floor heater is operated to start the operation, the control device 13 heats the water in the pipe-shaped heat exchanger 3 by the combustion of the combustion device 5. . The hot water temperature at this time is selected from the required temperature set and operated by the floor heater 3 or the air conditioner 4 (the hot water temperature requested by the air conditioner 4 is preferentially selected). The heated hot water flows into the floor heater 3 via the hot water pipe 7 by the operation of the circulation pump P, warms the floor heater 3 and heats the room by radiant heat to raise the room temperature. The control device 13 controls the on-off valve 8 based on the deviation between the room temperature and the set temperature to maintain a stable bed temperature.
[0020]
As shown in FIG. 4, the opening / closing valve 8 is controlled to open / close by setting an opening / closing ratio at regular intervals. For example, the heating capacity is increased by setting one cycle T to 20 minutes and the opening time t1 of the on-off valve 8 to 15 minutes, and the heating capacity is reduced by setting the opening time t2 to 5 minutes.
[0021]
Next, the control of opening and closing the on-off valve with respect to the deviation between the room temperature and the set temperature, the required hot water temperature of the floor heater, and the hot water temperature generated by the heat source device will be described.
[0022]
FIG. 5 is a table showing the on-off control of the on-off valve when the required hot water temperature of the floor heater is 65 ° C. and the hot water temperatures generated by the heat source device are 65 ° C., 70 ° C., and 75 ° C.
[0023]
When the required hot water temperature and the generated hot water temperature are both 65 ° C., when the deviation between the room temperature and the set temperature is 2 ° C. or more, the ON / OFF time of the on-off valve 8 is 2 minutes / 18 minutes, respectively. Similarly, when the temperature is between 1.5 ° C. and less than 2.0 ° C., 4 minutes / 16 minutes, when the temperature is between 1.0 ° C. and less than 1.5 ° C., 6 minutes / 14 minutes, and when the temperature is between 0.5 ° C. and less than 1.0 ° C. 8 minutes / 12 minutes, 10 minutes / 10 minutes when the temperature is 0 ° C or more and less than 0.5 ° C, 12 minutes / 8 minutes when the temperature is -0.5 ° C or more and less than 0 ° C, -1.0 ° C or more and -0.5 ° C When the temperature is less than 14 minutes / 6 minutes, when the temperature is -1.5 ° C or more and less than 1.0 ° C, 16 minutes / 4 minutes, when the temperature is -2.0 ° C or more and less than -1.5 ° C, 18 minutes / 2 minutes, -2 When the temperature is lower than 0.0 ° C., the ratio is 20 minutes / 0 minutes. As described above, since the ON / OFF time of the on-off valve is set according to the deviation between the room temperature and the set temperature, the heating capacity of the floor heater 3 can be automatically adjusted to perform appropriate floor heating.
[0024]
In addition, when the required hot water temperature of the floor heater 3 is 65 ° C. and the generated hot water temperature is 70 ° C., the ON time of the on-off valve is slightly shorter than in the case where the required hot water temperature and the generated hot water temperature are both 65 ° C. Set shorter. Similarly, when the required hot water temperature of the floor heater is 65 ° C. and the generated hot water temperature is 75 ° C., the ON time of the on-off valve 8 is set shorter. By setting the ON / OFF time of the on-off valve 8 by comparing the required hot water temperature with the actual hot water temperature, an appropriate floor heating operation can be performed even if the required hot water temperature and the generated hot water temperature are different. Can be implemented.
[0025]
FIG. 6 is a table showing the on-off control of the on-off valve when the required hot water temperature of the floor heater is 70 ° C. and the generated hot water temperatures are 65 ° C., 70 ° C., and 75 ° C.
[0026]
When the required hot water temperature is 70 ° C. and the generated hot water temperature is 70 ° C., the ON / OFF time of the on-off valve 8 is set to the same ON / OFF time as when the required hot water temperature and the generated hot water temperature are both 65 ° C. Is set to When the temperature of the generated hot water is 65 ° C. lower than the required temperature, the ON time is lengthened, and when the temperature of the generated hot water is 75 ° C. higher than the required temperature, the ON time is controlled to be shorter, so that appropriate floor heating is performed. You can drive.
[0027]
FIG. 7 is a table showing opening / closing control of the on-off valve when the required hot water temperature of the floor heater is 75 ° C. and the generated hot water temperatures are 65 ° C., 70 ° C., and 75 ° C.
[0028]
When the required hot water temperature and the generated hot water temperature are both 75 ° C., the ON / OFF time of the on-off valve is controlled in substantially the same manner as when the required hot water temperature and the generated hot water temperature are 65 ° C. in FIG. When the temperature of the generated hot water is 70 ° C. lower than the required temperature, the ON time is lengthened, and when the temperature of the generated hot water is 65 ° C., the ON time is further shortened, so that an appropriate floor heating operation can be performed.
[0029]
As described above, in the present embodiment, even if the hot water temperature requested by the floor heater 3 and the hot water temperature generated by the heat source unit 2 are different, the control device 23 sets the required hot water temperature as the detected hot water temperature. Since the ON / OFF time of the on-off valve 8 is controlled based on the temperature difference and the deviation between the room temperature and the set temperature, an appropriate floor heating operation can be performed, and comfortable floor heating can be realized.
[0030]
When the heating load is large, for example, at the start of operation or when the room temperature suddenly drops, the ON time of the on-off valve 8 is lengthened to shorten the rising time, and when the heating device is used in combination with a seasonal change or other time, heating is performed.
