【産業上の利用分野】
本発明は、複数の端末を出湯温度調節自在の一台の熱源機を用いて運転する温水式暖房装置における運転制御方法及びその装置に関する。
【0002】
【従来の技術】
一台の熱源機に複数台の端末を接続した温水式暖房装置であって、例えば端末が床暖房装置の場合、運転開始から室温が設定温度になるまでの所謂立上がり時には約80℃の温水を供給し、その後の定常運転時には約60℃の温水を供給するようになっている。
図4は、この従来の温水式暖房装置の例であって、1は出湯温度を約80℃と約60℃に制御自在の熱源機、2はガスバーナ、3は高温側出湯管、4は低温側出湯管、5は低温側出湯管4に取り付けられた温水ヘッダーであって、この温水ヘッダー5は端末ごとに設けられた配管接続口6と、個々に取り付けられた開閉弁7から成る。8は熱交換器、9は各端末からの戻り管、10は循環ポンプ、11は高温出湯管3と戻り管9を結ぶバイパス、12はシスターン、13、14は温度センサであって、熱源機1が高温に制御されている場合には、温水ヘッダー5からすべての端末(床暖房)へは高温の湯が供給され、低温に制御されている場合には、すべての端末へは低温の湯が一律に供給される構成である。
【0003】
【発明が解決しようとする課題】
このため、上記温水式暖房装置の場合、次のような欠点がある。
いま、端末A、B(室)が定常運転状態にあり、熱源機1から60℃の温水が供給されている時に、端末Cの運転が開始すると、定常運転中のA室、B室を優先させていることから、C室には60℃の温水がそのまま供給される。このため、C室の立上がり運転は60℃で行われることになる。したがって、床暖房が単独で立上がるときの温水温度を仮に80℃とすると、C室の床暖房はそれ単独で運転を開始したときの立上がり時に比べて立上がりが非常に遅くなる。

既に低温で定常運転中の端末が存在する間に新規に運転を開始した端末があった場合、この新規に運転を開始した端末が定常運転に移行するまでは、前記熱源機を高温運転に制御すると共に、既に定常運転に入っている端末の開閉弁の開時間を、あらかじめ計算された定常運転中に必要とする放熱量になる時間だけ開に制御する温水式暖房装置の運転制御方法。Hot water is supplied to a plurality of terminals from a single heat source unit configured to control the tapping temperature, and the hot water is supplied by branching the tapping side of the heat source unit and connecting each terminal in parallel with a hot water pipe. And, in the hot water type heating apparatus comprising an on-off valve for each terminal at a branch portion of the hot water pipe,
If there is a terminal that has newly started operation while a terminal that is already operating at a low temperature is already operating, the heat source unit is controlled to a high-temperature operation until the newly started terminal shifts to a normal operation. In addition, an operation control method for a hot-water heating apparatus that controls an opening time of an on-off valve of a terminal that is already in a steady operation to be opened only for a time that is a heat release amount required during a steady operation calculated in advance.
あらかじめ各端末ごとに運転の優先順位を決定しておき、既に低温で定常運転中の端末が存在する間に新規に運転を開始した端末があった場合、この新規に運転を開始した端末が定常運転中の端末よりその優先順位が上位のときにのみ新たに運転を開始した端末が定常運転に移行するまでは、既に定常運転中の端末に対する温水の供給を制限しながら前記熱源機を高温運転に制御する温水式暖房装置の運転制御方法。Hot water is supplied to a plurality of terminals from a single heat source unit configured to control the tapping temperature, and the hot water is supplied by branching the tapping side of the heat source unit and connecting each terminal in parallel with a hot water pipe. And, in the hot water type heating apparatus comprising an on-off valve for each terminal at a branch portion of the hot water pipe,
The priorities of operation are determined in advance for each terminal, and if there is a terminal that has newly started operation while there is a terminal that is already operating at a low temperature, this newly started terminal Until the terminal that newly started operation only when its priority is higher than the terminal that is operating shifts to the steady operation, the high-temperature operation of the heat source unit is performed while restricting the supply of hot water to the terminal that is already operating normally. Method for controlling the operation of a hot-water heating system controlled in a controlled manner.
