Description
【0001】[0001]
本考案は、熱媒体加熱用燃焼装置で得られた温水等の熱媒体により暖房を行う 暖房装置に関する。 The present invention relates to a heating device for heating with a heat medium such as hot water obtained by a heat medium heating combustion device.
【0002】[0002]
従来、熱媒体加熱用燃焼装置及び熱交換装置よりなるボイラで得られた温水等 の熱媒体により暖房を行う暖房装置は、例えば図3に示すように構成されている 。同図において、1は筐体、2は筐体1内に配置されたボイラ、3は循環ポンプ 、4は循環回路である。 Conventionally, a heating device for heating with a heat medium such as hot water obtained in a boiler including a heat medium heating combustion device and a heat exchange device is configured as shown in FIG. 3, for example. In the figure, 1 is a casing, 2 is a boiler arranged in the casing 1, 3 is a circulation pump, and 4 is a circulation circuit.
【0003】 5,5は筐体外に設置されたヘッダーであり、ヘッダー5,5間には、複数の 開閉弁6,6を介して床暖房パネル等の複数の放熱器7,7が並列に配管接続さ れている。8は循環回路4の戻り部に設けられた密閉膨張タンクであり、これに より循環回路4は密閉状態に保たれている。Reference numerals 5 and 5 are headers installed outside the housing, and a plurality of radiators 7 and 7 such as floor heating panels are arranged in parallel between the headers 5 and 5 via a plurality of open / close valves 6 and 6. Piping is connected. Reference numeral 8 is a closed expansion tank provided at the return portion of the circulation circuit 4, whereby the circulation circuit 4 is kept in a closed state.
【0004】 ボイラ2で加熱された温水等の熱媒体が循環回路4で放熱器7,7に循環され 、ここで室内空気を加熱した後、ボイラ2に戻され、再び加熱される。また、放 熱器7,7が設置された部屋の温度等に応じて開閉弁6,6が開閉され、これに 応じてボイラ2の加熱量が調整され、適度な暖房能力が得られるようにしてある 。A heat medium such as hot water heated in the boiler 2 is circulated in the radiators 7 and 7 in the circulation circuit 4, where the indoor air is heated and then returned to the boiler 2 to be heated again. In addition, the on-off valves 6 and 6 are opened and closed according to the temperature of the room in which the heat sinks 7 and 7 are installed, and the heating amount of the boiler 2 is adjusted accordingly, so that an appropriate heating capacity is obtained. There is.
【0005】[0005]
しかしながら、上述した暖房装置では、開閉弁6,6の開閉に伴い、ボイラ2 の暖房能力が変化しても、循環する熱媒体の総流量は一定であることから、暖房 能力の上限と下限では放熱器内の流速は大きく変化し、暖房能力の上限付近では 、騒音が生じる等の問題があった。また、暖房能力の下限付近では、放熱器に流 れる流速も過大となり、管壁が浸食され、穴あきを生じるなどの問題もあり、暖 房能力も不安定であった。 However, in the heating device described above, the total flow rate of the circulating heat medium is constant even if the heating capacity of the boiler 2 changes as the opening / closing valves 6 and 6 are opened / closed. There was a problem that the flow velocity in the radiator changed greatly and noise was generated near the upper limit of heating capacity. In addition, near the lower limit of the heating capacity, the flow velocity through the radiator was too high, and there were problems such as the erosion of the pipe wall and the formation of holes, and the heating capacity was unstable.
【0006】 本考案は、上述の事実に鑑みてなされたものであり、暖房負荷の変動にかかわ らず、各々の放熱器にそれぞれ常に略一定の熱媒体を供給できる暖房装置を提供 することを目的としている。The present invention has been made in view of the above facts, and provides a heating device capable of always supplying a substantially constant heat medium to each radiator regardless of the fluctuation of the heating load. Has an aim.
【0007】[0007]
本考案は、ボイラで得られた温水等の熱媒体により暖房を行う暖房装置におい て、循環回路の循環ポンプの吸込み側と吐出側の配管の双方に圧力センサを設け 、それらの圧力センサの差圧が一定になるように前記循環ポンプの回転を制御す る制御装置を備えた構成である。 The present invention is a heating device for heating with a heat medium such as hot water obtained from a boiler.In this system, pressure sensors are provided on both the suction side and the discharge side of the circulation pump of the circulation circuit. This is a configuration including a control device that controls the rotation of the circulation pump so that the pressure becomes constant.
【0008】[0008]
これにより、暖房負荷が増加したときには、熱媒体循環ポンプの回転数は増加 し、循環回路の総流量を増やし、また、暖房負荷が減少したときには、回転数が 減少し、循環回路の総流量を制限することで、各放熱器への流量を常に略一定に 保ち放熱を安定させることで、理想的な暖房が行えるものである。 As a result, when the heating load increases, the rotation speed of the heat medium circulation pump increases, increasing the total flow rate of the circulation circuit, and when the heating load decreases, the rotation speed decreases and the total flow rate of the circulation circuit decreases. By limiting the flow rate to each radiator, the flow rate to each radiator is kept almost constant and the heat radiation is stabilized.
【0009】 さらに、各放熱器に流れる流速も略一定となるため、管壁の浸食や穴あきも防 止される。Further, since the flow velocity of each radiator is substantially constant, erosion and perforation of the pipe wall are prevented.
【0010】[0010]
以下本考案の一実施例を図1の図面に基づいて説明する。図1において、1は 筐体、2は筐体1内に配置されたボイラ、3は循環ポンプ、4は循環回路である 。5,5は筐体外に配置されたヘッダーであり、ヘッダー5,5間には、複数の 開閉弁6,6を介して床暖房パネル等の複数の放熱器7,7が並列に配管接続さ れている。8は循環回路4の戻り部に設けられた密閉膨張タンクであり、これに より循環回路4は密閉状態に保たれている。 An embodiment of the present invention will be described below with reference to FIG. In FIG. 1, 1 is a casing, 2 is a boiler arranged in the casing 1, 3 is a circulation pump, and 4 is a circulation circuit. Reference numerals 5 and 5 are headers arranged outside the housing. Between the headers 5 and 5, a plurality of radiators 7 and 7 such as floor heating panels are connected in parallel via a plurality of open / close valves 6 and 6. Has been. Reference numeral 8 is a closed expansion tank provided at the return portion of the circulation circuit 4, whereby the circulation circuit 4 is kept in a closed state.
【0011】 9,9は、筐体内にある循環回路4の循環ポンプ3の吸込み側と吐出側の配管 の双方に設けられた、静圧を検出する圧力センサであり、圧力センサ9,9は、 循環ポンプの回転を制御する制御装置10に接続されている。この制御装置10 は、圧力センサ9,9によって差圧を検出することにより、図2に示すように、 循環ポンプ3の回転数を制御して、熱媒体の吐出量を変化させるものである。Reference numerals 9 and 9 are pressure sensors provided on both the suction side and the discharge side of the circulation pump 3 of the circulation circuit 4 in the housing for detecting static pressure. , Is connected to a control device 10 that controls the rotation of the circulation pump. The control device 10 controls the rotation speed of the circulation pump 3 to change the discharge amount of the heat medium by detecting the differential pressure by the pressure sensors 9 and 9, as shown in FIG.
【0012】 すなわち、開閉弁6,6が開き、暖房負荷が大きくなると、圧力センサ9,9 によって検出された差圧が所定値より小さくなるため、制御装置10は循環ポン プ3の回転数を大きくし、循環ポンプ3の吐出量を増加させる。逆に、開閉弁6 ,6が閉じ、暖房負荷が小さくなると、圧力センサ9,9によって検出された差 圧が所定値より大きくなるため、制御装置10は循環ポンプ3の回転数を小さく し、循環ポンプ3の吐出量を減少させる。このため、暖房装置の変動にかかわら ず、各々の放熱器7にそれぞれ常に略一定の熱媒体を供給できる。That is, when the on-off valves 6 and 6 are opened and the heating load increases, the differential pressure detected by the pressure sensors 9 and 9 becomes smaller than a predetermined value, so that the control device 10 controls the rotation speed of the circulation pump 3. It is increased to increase the discharge amount of the circulation pump 3. On the contrary, when the on-off valves 6 and 6 are closed and the heating load becomes small, the differential pressure detected by the pressure sensors 9 and 9 becomes larger than a predetermined value, so that the control device 10 reduces the rotation speed of the circulation pump 3. The discharge amount of the circulation pump 3 is reduced. Therefore, it is possible to always supply a substantially constant heat medium to each radiator 7 regardless of the fluctuation of the heating device.
【0013】[0013]
本考案の暖房装置によると、循環ポンプの吐出側と吸込み側の差圧が一定にな るように、循環ポンプの回転を制御する制御回路を設けたことにより、暖房用放 熱器の暖房負荷が増加したときには、熱媒体循環ポンプの回転数が増加し吐出量 を増やし、また、暖房負荷が減少したときには、回転数が減少し吐出量を制限す ることで、各放熱器への流量を常に略一定にし放熱を安定させることで、理想的 な暖房が行えるものである。 According to the heating device of the present invention, by providing the control circuit for controlling the rotation of the circulation pump so that the differential pressure between the discharge side and the suction side of the circulation pump becomes constant, the heating load of the heating heat sink is increased. When the heating medium circulation pump increases, the number of rotations of the heat medium circulation pump increases to increase the discharge amount, and when the heating load decreases, the number of rotations decreases and the discharge amount is limited, thereby reducing the flow rate to each radiator. Ideal heating can be achieved by making the heat radiation stable and almost constant.
【0014】 さらに、放熱器に流れる流速も略一定となるため、管壁の浸食や穴あきを防げ るという効果を奏する。Further, since the flow velocity flowing through the radiator is also substantially constant, there is an effect that erosion and perforation of the pipe wall can be prevented.
【0015】 また、上述した実施例のように、密閉膨張タンクを有する密閉式の循環回路を 用いることにより、熱媒体の蒸発が少なくなり、ゴミの侵入を防止することがで きる。Further, as in the above-described embodiment, by using the closed circulation circuit having the closed expansion tank, the evaporation of the heat medium is reduced and the invasion of dust can be prevented.
