この発明は、石油瞬間ボイラによって得られた温湯をフ
ァンコイルユニットに供給するように構成した暖房シス
テムに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating system configured to supply hot water obtained by an oil instantaneous boiler to a fan coil unit.
この種の暖房システムにおいて、石油瞬間ボイラの起動

に供給される温湯、または各ファンコイル・ユニットか
らボイラに戻る温湯の温度にもとづいて行われる。In this type of heating system, starting and stopping control of the oil instantaneous boiler is performed based on the temperature of hot water supplied from the boiler to each fan coil unit or hot water returned from each fan coil unit to the boiler.
しかしながら複数のファンコイル・ユニットのうちのい
くつかが休止状態にある場合には、循環する温湯の流量
が減少するので、ボイラの起動・停止によって湯温が太
幅に変動し、普た熱効率も低い。However, if some of the multiple fan coil units are in a dormant state, the flow rate of circulating hot water decreases, and the hot water temperature fluctuates widely when the boiler starts and stops, resulting in poor thermal efficiency. low.
この発明は、循環する温湯の温度と流量の両方にもとづ

ことを目的としている。An object of the present invention is to provide a heating system in which the temperature of hot water can be precisely controlled by controlling the operation of an oil instantaneous boiler based on both the temperature and flow rate of circulating hot water.
つぎにこの発明の一実施例について図面を参照して説明
する。Next, an embodiment of the present invention will be described with reference to the drawings.

ている温湯を加熱する。The petroleum instantaneous boiler indicated by reference numeral 1 in the figure operates only while the heat request signal is supplied from the comparator 2, and is operated by the action of the pump 3 to connect the supply pipe 4, multiple nofan coil units) 5-
1. Heat the hot water circulating through 5-2 to 5-n and return line 6.
なおボイラ１は、熱要求信号の大きさに応じて発熱量を
切換えるようなものであってもよい。Note that the boiler 1 may be of a type that switches the amount of heat generated depending on the magnitude of the heat request signal.

演算回路９に供給される。Further, a temperature sensor 7 for detecting the temperature of the hot water flowing inside the return pipe 6 and a flow sensor 8 for detecting the flow rate of this hot water are inserted into the return pipe 6, and the output signals of both are sent to the calculation circuit 9. Supplied.
そしてこの演算回路９の出力信号は、前述の比較回路２
ＩＬおいて、あらかじめ設定された設定値ＳＰと比較さ
れる。The output signal of this arithmetic circuit 9 is then
In IL, it is compared with a preset setting value SP.
演算回路９は、基本的には、温度センサ１から与えられ
た温度信号と、フローセンサ８から与えられた流量信号
との積を究める掛算回路として働く。The arithmetic circuit 9 basically functions as a multiplication circuit that calculates the product of the temperature signal given from the temperature sensor 1 and the flow rate signal given from the flow sensor 8.
この掛算によって得られる値は、ボイラ１に戻される温
湯が保有している熱量にほかならない。The value obtained by this multiplication is nothing but the amount of heat held by the hot water returned to the boiler 1.
したがってこの演算回路９の出力信号を設定値ＳＰと比
較することによって得られる信号は、ボイラ１によって
供給されるべき熱量を示す熱要求信号となり、この信号
にもとづいてボイラ１の起動・停止を制御することによ

きる。Therefore, the signal obtained by comparing the output signal of the arithmetic circuit 9 with the set value SP becomes a heat request signal indicating the amount of heat to be supplied by the boiler 1, and the start/stop of the boiler 1 is controlled based on this signal. By doing so, it is possible to supply an amount of heat that accurately corresponds to the heating load.
また演算回路９において、温度センサγの出力信号をフ
ローセンサ８の出力信号によってカスケード制御しても
よい。Further, in the arithmetic circuit 9, the output signal of the temperature sensor γ may be cascade-controlled by the output signal of the flow sensor 8.
以上のようにこの発明によれば、石油瞬間ボイラ１の起
動・停止は、温度センサ７およびフローセンサ８の検出
信号から演算回路９で求められた暖房負荷にもとづいて
制御される。As described above, according to the present invention, starting and stopping of the oil instantaneous boiler 1 is controlled based on the heating load determined by the calculation circuit 9 from the detection signals of the temperature sensor 7 and the flow sensor 8.
したがって各ファンコイル・ユニット５−１〜５−ｎＦ

で安定した暖房効果が得られる。Therefore, each fan coil unit 5-1 to 5-nF
It becomes possible to supply an optimal amount of heat to the air conditioner c, and a precise and stable heating effect can be obtained.
