Description

この発明は、吸収式冷凍機能により冷水の冷却または温水の加温を行うようにした装置（この発明において、吸収式冷凍装置という）であって、特に、こうした熱負荷に供給する熱容量を大きくした吸収式冷凍装置に関するものである。   The present invention is an apparatus that cools cold water or warms water by means of an absorption refrigeration function (referred to in this invention as an absorption refrigeration apparatus), and in particular, increases the heat capacity supplied to such a heat load. The present invention relates to an absorption refrigeration apparatus.

吸収式冷凍機能として、例えば、吸収剤を臭化リチウム、冷媒を水として混合した臭化リチウム水溶液などの吸収液を用いたる吸収式冷凍機装置が周知であり、一般的な熱容量により冷水を冷却する構成の得る冷水供給型の吸収式冷凍機装置として、図７のような吸収式冷凍装置１００の構成（以下、第１従来技術という）が、後記特許文献1により開示されている。   As an absorption refrigeration function, for example, an absorption refrigeration apparatus using an absorption liquid such as a lithium bromide aqueous solution mixed with lithium bromide as an absorbent and water as a refrigerant is well known, and cool water is cooled by a general heat capacity. As a chilled water supply type absorption chiller device that can be obtained, a configuration of an absorption refrigeration device 100 as shown in FIG. 7 (hereinafter referred to as a first prior art) is disclosed in Patent Document 1 described later.

なお、この第１従来技術の構成の場合には、点線で示した管路１８・１９と開閉弁Ｖ５・Ｖ６とが無く、また、（温水入口）（温水出口）が無く、符号２２ａが冷水のみになっているものである。
そして、以下に説明する各図において、同一の符号で示す部分は、いずれかの図によって説明する同一符号の部分と同一の機能を有する部分である。 In the case of the configuration of the first prior art, there are no pipe lines 18 and 19 and open / close valves V5 and V6 indicated by dotted lines, there is no (hot water inlet) (hot water outlet), and reference numeral 22a is cold water. It is what is only.
And in each figure demonstrated below, the part shown with the same code | symbol is a part which has the same function as the part of the same code | symbol demonstrated with any figure.

図７の構成において、まず、吸収液の循環系を、吸収器５の底部に溜っている低濃度の吸収液５ａを起点として説明すると、吸収液５ａは、ポンプ１３により、管路９を経て、高温再生器１に入り、吸収液１ａとして貯留される。高温再生器1は、バーナーなどの加熱器３１で加熱しているので、吸収液１ａに中に含まれている冷媒が蒸発して、高温になった中濃度の吸収液1ｃと、冷媒蒸気1ｂとに分離する。   In the configuration of FIG. 7, first, the circulation system of the absorption liquid will be described starting from the low concentration absorption liquid 5 a accumulated at the bottom of the absorber 5. The absorption liquid 5 a is passed through the pipe line 9 by the pump 13. Then, it enters the high-temperature regenerator 1 and is stored as the absorbent 1a. Since the high-temperature regenerator 1 is heated by a heater 31 such as a burner, the refrigerant contained in the absorbing liquid 1a evaporates, and the medium-concentrated absorbing liquid 1c and the refrigerant vapor 1b are heated. And to separate.

なお、加熱器３１は、燃料供給口から供給される燃料３１ａと、送風機３１ｂからの空気量とを、流量調整弁Ｖ２１、すなわち、燃料制御弁Ｖ２１で調整して供給するとともに、点火器３１ｃにより点火されて、加熱を行うように構成してある。   The heater 31 adjusts and supplies the fuel 31a supplied from the fuel supply port and the air amount from the blower 31b with the flow rate adjusting valve V21, that is, the fuel control valve V21, and is also supplied by the igniter 31c. It is configured to be ignited and heated.

そして、高温の吸収液１ｃは、管路１０から、高温側熱交換器７に入り、管路９を通る吸収液５ａに熱を与えて放熱し、温度が低下した後、管路１０を経て、低温再生器２に入る。低温再生器２では、管路１４から送り込まれた冷媒蒸気１ｂが放熱管２Ａを加熱しているので、この加熱により吸収液１ｃに含まれている冷媒が蒸発して、高温になった高濃度の吸収液２ａと、冷媒蒸気２ｃとに分離する。   And the high temperature absorption liquid 1c enters into the high temperature side heat exchanger 7 from the pipe line 10, gives heat to the absorption liquid 5a passing through the pipe line 9, and dissipates it. And enters the low temperature regenerator 2. In the low temperature regenerator 2, since the refrigerant vapor 1b sent from the pipe line 14 heats the heat radiating pipe 2A, the refrigerant contained in the absorption liquid 1c is evaporated by this heating, and the high concentration becomes high. The absorption liquid 2a and the refrigerant vapor 2c are separated.

高温の吸収液２ａは、管路１１から、低温側熱交換器６に入り、管路９を通る吸収液５ａに熱を与えて放熱し、中温になった後、管路１１を経て、吸収器５内に吸収液５ｂとして散布される。吸収器５内の冷却管５Ａは、管路２３から供給される冷却用水２３ａによって冷却されているので、散布された吸収液５ｂは、冷却管５Ａに沿って流下する際に、隣接する蒸発器４から入ってくる冷媒蒸気４ｂを吸収して稀薄化し、低温で濃度の希薄な吸収液５ａに戻り、吸収液の一巡が終えるという吸収液循環を繰り返すものである。   The high-temperature absorption liquid 2a enters the low-temperature side heat exchanger 6 from the pipe 11 and gives heat to the absorption liquid 5a passing through the pipe 9 to dissipate it. After reaching a medium temperature, the high-temperature absorption liquid 2a is absorbed through the pipe 11 The absorbent 5 is sprayed in the container 5. Since the cooling pipe 5A in the absorber 5 is cooled by the cooling water 23a supplied from the pipe 23, when the sprayed absorbent 5b flows down along the cooling pipe 5A, the adjacent evaporator 5A is cooled. The refrigerant vapor 4b coming from 4 is absorbed and diluted, and the absorption liquid circulation is repeated, returning to the absorption liquid 5a having a low concentration at a low temperature and completing one cycle of the absorption liquid.

次に、冷媒の循環系を、吸収器５に入った冷媒蒸気４ｂを起点にして説明すると、冷媒蒸気４ｂは、上記の吸収液の循環系で説明したように、吸収器５内に分散された高濃度の吸収液５ｂに吸収されて、吸収液５ａの中に入り、高温再生器１で冷媒蒸気１ｂになる。冷媒蒸気１ｂは、管路１４を経て、低温再生器２の放熱管２Ａに入り、中間濃度の吸収液１ｃに熱を与えて放熱し、凝縮して冷媒液２ｂになった後、管路１４Ａを経て、凝縮器３の底部に入る。   Next, the refrigerant circulation system will be described with the refrigerant vapor 4b entering the absorber 5 as a starting point. The refrigerant vapor 4b is dispersed in the absorber 5 as described in the above-described absorption liquid circulation system. It is absorbed by the high-concentration absorbing liquid 5b and enters the absorbing liquid 5a to become the refrigerant vapor 1b in the high-temperature regenerator 1. The refrigerant vapor 1b enters the heat radiating pipe 2A of the low-temperature regenerator 2 through the pipe line 14, heats the intermediate concentration absorbing liquid 1c to dissipate it, condenses into the refrigerant liquid 2b, and then the pipe line 14A. And enters the bottom of the condenser 3.

凝縮器３では、隣接する低温再生器２から入ってくる冷媒蒸気２ｃを、凝縮器３内の冷却管３Ａを通る冷却用水２３ａで冷却して凝縮し、低温の冷媒液３ａにする。低温の冷媒液３ａは、冷媒液２ｂと合流し、管路１５から蒸発器４に入り、蒸発器４の底部に溜まって冷媒液４ａになる。   In the condenser 3, the refrigerant vapor 2c entering from the adjacent low-temperature regenerator 2 is cooled and condensed with cooling water 23a passing through the cooling pipe 3A in the condenser 3 to form a low-temperature refrigerant liquid 3a. The low-temperature refrigerant liquid 3a merges with the refrigerant liquid 2b, enters the evaporator 4 through the conduit 15, and accumulates at the bottom of the evaporator 4 to become the refrigerant liquid 4a.

低温の冷媒液４ａは、ポンプ２０によって、管路１６から蒸発器４内に散布され、蒸発器４内の熱交換管４Ａを通る冷水２２ａを冷却する。この冷却の際に、冷媒液４ａは、冷水２２ａから熱を吸収して冷媒蒸気４ｂになった後、隣接する吸収器５に戻り、冷媒の一巡が終えるという冷媒循環を繰り返すものである。   The low-temperature refrigerant liquid 4a is sprayed into the evaporator 4 from the pipe line 16 by the pump 20, and cools the cold water 22a passing through the heat exchange pipe 4A in the evaporator 4. During this cooling, the refrigerant liquid 4a absorbs heat from the cold water 22a to become the refrigerant vapor 4b, and then returns to the adjacent absorber 5 to repeat the refrigerant circulation in which one cycle of the refrigerant is completed.

そして、温度検出器ＴＤ１で検出した冷水２２ａの入口側の温度ｔ１と、温度検出器ＴＤ２で検出した冷水２２ａの出口側の温度ｔ２とにもとづいて、冷水２２ａを所要の温度に制御するために、燃料調整弁Ｖ２１によって、高温再生器1の加熱器３１の加熱量を制御するように構成している。   In order to control the cold water 22a to a required temperature based on the temperature t1 on the inlet side of the cold water 22a detected by the temperature detector TD1 and the temperature t2 on the outlet side of the cold water 22a detected by the temperature detector TD2. The heating amount of the heater 31 of the high temperature regenerator 1 is controlled by the fuel adjustment valve V21.

なお、装置の運転を起動する際には、高温再生器１内の吸収液１ａの量が不足して、高温再生器１が空焚きにならぬように、開閉弁Ｖ４を開いて、ポンプ２０を運転することにより、蒸発器４の底部に溜まっている冷媒液４ａを吸収器1の底部に溜まっている吸収液５ａとともに、ポンプ１３によって高温再生器１に入れている。   When starting the operation of the apparatus, the pump 20 is opened by opening the on-off valve V4 so that the amount of the absorbent 1a in the high temperature regenerator 1 is insufficient and the high temperature regenerator 1 does not become empty. , The refrigerant liquid 4a accumulated at the bottom of the evaporator 4 is put into the high temperature regenerator 1 by the pump 13 together with the absorbent 5a accumulated at the bottom of the absorber 1.

上記の第１従来技術による吸収式冷凍装置１００の構成では、冷水２２ａのみを供給するように構成しているが、こうした構成に、冷水２２ａを供給する冷却運転に代えて、冷水２２ａを温水２２ａに変更して供給する加温運転をも行い得るようにした冷温水切換供給型の吸収式冷凍装置１００の構成（以下、第２従来技術という）が、後記特許文献１により開示されている。   In the configuration of the absorption refrigeration apparatus 100 according to the first conventional technique, only the cold water 22a is supplied. Instead of the cooling operation for supplying the cold water 22a, the cold water 22a is replaced with the hot water 22a. A configuration of an absorption refrigeration apparatus 100 of a cold / hot water switching supply type (hereinafter, referred to as a second prior art) that can also perform a heating operation that is changed to be supplied is disclosed in Patent Document 1 described later.

なお、吸収式冷凍装置１００を空調装置に用いた場合には、上記の冷却運転は、主として冷房に用いるので、冷房運転とも呼ばれ、また、上記の加温運転は、主として暖房に用いるので、暖房運転とも呼ばれているが、冷水・温水の用途は、空調用以外の用途、例えば、工業生産における物品の冷却・加温や、商品の冷却・加温などに用いられる場合があるので、この発明では、こうした用途を含めて、「冷却運転」「加温運転」と言うものである。   In addition, when the absorption refrigeration apparatus 100 is used for an air conditioner, the above cooling operation is mainly used for cooling, so it is also called a cooling operation, and the above heating operation is mainly used for heating. Although it is also called heating operation, the use of cold water / hot water may be used for applications other than air conditioning, for example, cooling / heating of goods in industrial production, cooling / heating of goods, etc. In the present invention, including such applications, it is referred to as “cooling operation” or “heating operation”.

そして、第２従来技術による冷温水切換供給型の吸収式冷凍装置１００構成の場合には、図７に点線で画いてあるように、管路１８・管路１９と、開閉弁Ｖ５・開閉弁Ｖ６とを設けてあり、上記の第１従来技術と同様の冷却運転を行う際には、開閉弁Ｖ５・開閉弁Ｖ６を閉じて行い、上記の加温運転を行う際には、開閉弁Ｖ５・開閉弁Ｖ６を開いて行うように構成したものである。   And, in the case of the configuration of the absorption refrigeration apparatus 100 of the cold / hot water switching supply type according to the second prior art, as shown by the dotted line in FIG. 7, the pipeline 18, the pipeline 19, the on-off valve V5, the on-off valve V6 is provided, and when performing the same cooling operation as the first prior art, the on-off valve V5 and the on-off valve V6 are closed, and when performing the above-described heating operation, the on-off valve V5 is provided. -Opening and closing valve V6 is configured to be performed.

つまり、開閉弁Ｖ５・開閉弁Ｖ６を開いて、高温再生器１で蒸発分離した冷媒蒸気１ｂと、中間濃度の吸収液１ｃとを、管路１８・管路１９により側路して、直接、吸収器５に戻し入れるとともに、冷却用水２３ａの流通を停止して、低温再生器２・凝縮器３を用いずに、高温再生器１のみの運転によって、吸収液循環と冷媒循環とを行いながら蒸発器４内の熱交換管４Ａを通る温水２２ａを加温する。   That is, the on-off valve V5 and the on-off valve V6 are opened, and the refrigerant vapor 1b evaporated and separated in the high temperature regenerator 1 and the intermediate concentration absorbent 1c are bypassed by the pipe line 18 and the pipe line 19, and directly While returning to the absorber 5, the circulation of the cooling water 23 a is stopped, and the absorption liquid circulation and the refrigerant circulation are performed by operating only the high temperature regenerator 1 without using the low temperature regenerator 2 and the condenser 3. Warm water 22a passing through the heat exchange pipe 4A in the evaporator 4 is heated.

そして、温度検出器ＴＤ1で検出した温水２２ａの入口側の温度ｔ１と、温度検出器ＴＤ２で検出した温水２２ａの出口側の温度ｔ２とにもとづいて、温水２２ａを所要の温度に制御するために、燃料調整弁Ｖ２１によって、高温再生器1の加熱器３１の加熱量を制御するように構成している。   In order to control the hot water 22a to a required temperature based on the temperature t1 on the inlet side of the hot water 22a detected by the temperature detector TD1 and the temperature t2 on the outlet side of the hot water 22a detected by the temperature detector TD2. The heating amount of the heater 31 of the high temperature regenerator 1 is controlled by the fuel adjustment valve V21.

したがって、上記の第１従来技術・第２従来技術の構成は、いずれも、高温再生器１で蒸発させた冷媒蒸気１ｂにもとづいて、冷水２２ａ・温水２２ａ、すなわち、熱負荷に熱供給を行っているものであり、この熱供給の熱容量、すなわち、熱負荷に対する熱容量は、冷媒蒸気１ｂを蒸発させるための高温再生器１の加熱容量αによって定まることになるわけである。   Therefore, the configurations of the first and second prior arts described above both supply heat to the cold water 22a and the hot water 22a, that is, the heat load, based on the refrigerant vapor 1b evaporated by the high temperature regenerator 1. Therefore, the heat capacity of the heat supply, that is, the heat capacity with respect to the heat load is determined by the heating capacity α of the high-temperature regenerator 1 for evaporating the refrigerant vapor 1b.

また、上記の第１従来技術・第２従来技術による吸収式冷凍装置１００の構成に加えて、工業排水などを熱源水とする第２の低温再生器・凝縮器などを設けた吸収式冷凍装置１００の構成（以下、第３従来技術という）が、後記特許文献２により開示されている。   Further, in addition to the configuration of the absorption refrigeration apparatus 100 according to the first conventional technique and the second conventional technique, an absorption refrigeration apparatus provided with a second low-temperature regenerator / condenser etc. that uses industrial wastewater as heat source water. A configuration of 100 (hereinafter referred to as “third prior art”) is disclosed in Patent Document 2 described later.

ところで、上記の第１従来技術〜第３従来技術の構成において、高温再生器１を起動させて、吸収液１ａを所要の温度に上昇させた後の運転では、加熱器３１の加熱量を熱負荷に対応させるように、燃料制御弁Ｖ２１を制御するが、この加熱量が小さい範囲では、加熱器３１における燃料ガス３１ａの不完全燃焼などによる事故を生じ易いため、図９のように、高温再生器１の加熱容量αの２５％程度の加熱量までは、熱負荷に比例させるような制御を行うことができない。   By the way, in the configuration of the first to third prior arts described above, in the operation after the high temperature regenerator 1 is started and the absorbing liquid 1a is raised to a required temperature, the heating amount of the heater 31 is increased. Although the fuel control valve V21 is controlled so as to correspond to the load, an accident due to incomplete combustion of the fuel gas 31a in the heater 31 is likely to occur in a range where the heating amount is small. Controls proportional to the heat load cannot be performed up to a heating amount of about 25% of the heating capacity α of the regenerator 1.

このため、例えば、加熱量が加熱容量αの２５％程度以下の範囲では、加熱器３１の燃料制御弁Ｖ２１の弁開度γを２５％程度にした状態で、点火と消火とをごく短い時間間隔で繰り返して加熱（この発明において、「発停加熱」という）する制御（この発明において、「発停制御」という）を行っている。   For this reason, for example, when the heating amount is in the range of about 25% or less of the heating capacity α, the ignition and extinguishing time is extremely short with the valve opening γ of the fuel control valve V21 of the heater 31 being about 25%. Control (referred to as “start / stop control” in the present invention) for heating (referred to as “start / stop heating” in this invention) is performed repeatedly at intervals.

そして、図９のように、発停制御により加熱する領域、すなわち、発停制御領域Ｘの上限を比例制御開始点Ｙ１として、それ以上の領域を熱負荷に対応させた比例制御領域Ｙとするように構成している。   And as shown in FIG. 9, the area | region heated by start / stop control, ie, the upper limit of the start / stop control area | region X is made into the proportional control start point Y1, and the area beyond it is made into the proportional control area | region Y corresponding to the heat load. It is configured as follows.

そして、上記の第１従来技術〜第３従来技術による吸収式冷凍装置１００には、上記のような各運転動作のための制御処理を行う部分として、制御部３０を設けてあり、具体的には、例えば、図８の制御部３０のような構成が周知であり、図８において、制御部３０は、マイクロコンピュータによる処理制御器、例えば、市販のＣＰＵボード（ＣＰＵ／Ｂ）を主体にして構成した制御部である。   And in the absorption refrigeration apparatus 100 by said 1st prior art-3rd prior art, the control part 30 is provided as a part which performs the control processing for each above driving | operation operation | movement, Specifically, For example, the configuration of the control unit 30 in FIG. 8 is well known. In FIG. 8, the control unit 30 is mainly composed of a microcomputer-based processing controller, for example, a commercially available CPU board (CPU / B). It is a configured control unit.

そして、各部の温度を検出した検出信号、各開閉弁・制御弁の開閉状態・弁開度を検出した検出信号、各ポンプの運転信号などと、入力操作部分３６、例えば、キーボードから入力した操作データ・設定データなどを入出力ポート３０Ａから取り込み、各データを作業用メモリ３３に一時的に記憶した各データと、処理用メモリ３２に予め記憶した制御処理フローによるプログラムと、データ用メモリ３４に予め記憶した所定温度値・所定時間値などの基準値データなどと、計時回路３５で計時した経過時間・所定時刻などの時間値データなどとにもとづいて、所要の演算処理などを行って得られる各制御信号を入出力ポート３０Ａから各制御部分に出力するとともに、作業メモリ３３などに記憶している記憶データの内容から所要のものを表示部分３７、例えば、液晶画面による表示部に与えて表示するように構成したものである。   Then, a detection signal for detecting the temperature of each part, a detection signal for detecting the opening / closing state / opening degree of each on-off valve / control valve, an operation signal for each pump, and an operation input from the input operation part 36, for example, a keyboard Data, setting data, and the like are fetched from the input / output port 30A, each data is temporarily stored in the work memory 33, a program according to a control processing flow stored in the processing memory 32 in advance, and the data memory 34 It is obtained by performing a required calculation process based on reference value data such as a predetermined temperature value and a predetermined time value stored in advance and time value data such as an elapsed time and a predetermined time measured by the timer circuit 35. Each control signal is output from the input / output port 30A to each control part, and the required data is stored from the contents of the stored data stored in the work memory 33 or the like. Radical 113 min 37, for example, which is constituted to display given on the display unit by the LCD screen.

そして、上記の第１従来技術〜第３従来技術の構成において、熱負荷に対する熱供給の熱容量を増加させるためには、高温再生器１の吸収液１ａを加熱する熱容量を増加させる必要があるので、高温再生器１の加熱器３１の有効加熱量を向上させるように加熱構成を改良した構成（以下、第４従来技術という）が試みられており、後記特許文献３・４により開示されている。
特開平６−８８６５４号公報 特開平１１−２８１１８５号公報 特開平９−１４７９１号公報 特開平１０−１６９９０３号公報 And in the structure of said 1st prior art-3rd prior art, in order to increase the heat capacity of the heat supply with respect to a heat load, it is necessary to increase the heat capacity which heats the absorption liquid 1a of the high temperature regenerator 1.

上記の第１従来技術〜第３従来技術の吸収式冷凍装置１００を設置する対象施設などが大型化するなどにより、高温再生器１の加熱容量αを増大させる必要がある場合に、上記の第４従来技術の構成による改良では、装置の構成が複雑高価になるほか、その開発投資がかさみ、装置を簡便安価な構成にして提供し得ないという不都合がある。   When it is necessary to increase the heating capacity α of the high-temperature regenerator 1 due to an increase in size of a target facility in which the absorption refrigeration apparatus 100 according to the first to third prior arts is installed, the above-described first 4. The improvement by the configuration of the prior art has a disadvantage that the configuration of the device becomes complicated and expensive, and the development investment is increased, and the device cannot be provided in a simple and inexpensive configuration.

また、これらの従来技術における高温再生器１の構成をそのまま大型にしたのでは、上記の発停制御領域Ｘの領域が大きくなって燃料経費が不経済になるほか、高温再生器１の高さが大きくなり過ぎて、設置場所の建築構造を高構造にする必要があり、需要対象が制限されるなどの不都合が生ずる。   Further, if the configuration of the high-temperature regenerator 1 in these prior arts is increased as it is, the above-described start / stop control region X becomes larger, resulting in uneconomical fuel costs and the height of the high-temperature regenerator 1. Becomes too large, and it is necessary to make the building structure of the installation place high, resulting in inconveniences such as a restriction of the target of demand.

さらに、冷水または温水に熱供給を行う加熱量の変化の過程中に、上記の発停制御領域Ｘによる加熱量の変動が生じて、熱供給を混乱させてしまうなどの不都合が生ずる。
このため、こうした不都合の無い大熱容量型の吸収式冷凍装置の提供が望まれているという課題がある。 In addition, during the process of changing the heating amount for supplying heat to cold water or hot water, the heating amount fluctuates due to the on / off control region X, and the heat supply is confused.
For this reason, there is a problem that it is desired to provide a large heat capacity type absorption refrigeration apparatus without such inconvenience.

前段の上記の高温再生器、すなわち、前段再生器における発停制御領域、すなわち、前段発停領域を超えた比例制御領域による加熱量の範囲と、次段の上記の高温再生器、すなわち、次段再生器における発停制御領域、すなわち、次段発停領域を超えた比例制御領域による加熱量の範囲とを直列させて上記の供給加熱制御を行うことにより、上記の前段発停領域と上記の次段発停領域とによる加熱量の変動を除去する発停領域変動除去手段

When the increase in the heating amount by the preceding stage regenerator reaches the maximum value of the heating capacity of the preceding stage regenerator, heating by the heating amount in the proportional control region of the next stage regenerator is started. By suppressing the heating amount by the preceding stage regenerator by a heating amount corresponding to the heating capacity of the next stage start / stop region, the rapid increase in the supply heating amount accompanying the heating by the next stage regenerator is suppressed. Rapid increase suppression means for performing the above-described supply heating control,

上記の低減を行った加熱量を上記の前段再生器の上記の比例制御領域により再び増加させる加熱と、上記の次段再生器の上記の比例制御領域により増加させる加熱とを直列させて上記の供給加熱制御を行う直列比例増加手段と
を設ける第６の構成とにより、上記の課題を解決したものである。 The above-described reduction heating amount is increased again by the proportional control region of the preceding regenerator and the heating amount is increased by the proportional control region of the next-stage regenerator in series to The above-described problem is solved by a sixth configuration including a series proportional increase means for performing supply heating control.

この発明によれば、複数の高温再生器を設けて、熱負荷に対する熱供給の熱容量を増大しているため、既存の高温再生器をそのまま用いて熱容量を増大し得るので、加熱器を特殊な構成にするなどの複雑に変更することなく、大熱容量型の吸収式冷凍装置を簡便安価に提供し得るという特長がある。   According to the present invention, since a plurality of high-temperature regenerators are provided to increase the heat capacity of the heat supply to the heat load, the heat capacity can be increased using the existing high-temperature regenerator as it is. There is a feature that a large heat capacity type absorption refrigeration apparatus can be provided simply and inexpensively without complicated changes such as configuration.

また、前段の高温再生器の吸収液・冷媒蒸気を次段の高温再生器に与え、前段の高温再生器の吸収液液面レベルを次段の高温再生器の吸収液液面レベルよりも高くする落差を設けるなどにより、吸収液・冷媒蒸気の流れを方向づけているので、冷温水機能に対する吸収液・冷媒蒸気の流動を安定に行わせ得るという特長がある。   Also, the absorption liquid / refrigerant vapor of the previous high temperature regenerator is given to the next high temperature regenerator, and the absorption liquid level of the previous high temperature regenerator is higher than the absorption liquid level of the next high temperature regenerator. Since the flow of the absorption liquid / refrigerant vapor is directed by providing a drop or the like, there is a feature that the flow of the absorption liquid / refrigerant vapor with respect to the cold / hot water function can be performed stably.

さらに、前段の高温再生器の熱容量を小さく次段の高温再生器の熱容量を大きくして、前段の高温再生器の発停制御領域を超えた比例制御領域による加熱量の範囲と、次段の高温再生器の発停制御領域を超えた比例制御領域による加熱量の範囲と直列させて、供給加熱量の制御を行っているので、前段・次段の各高温再生器の各発停制御領域による加熱量の変動を除去し得るという特長がある。   In addition, the heat capacity of the high temperature regenerator in the previous stage is reduced and the heat capacity of the high temperature regenerator in the next stage is increased, and the range of the heating amount in the proportional control region beyond the start / stop control region of the high temperature regenerator in the previous stage, The supply heating amount is controlled in series with the range of heating amount in the proportional control region that exceeds the start / stop control region of the high-temperature regenerator, so each start-and-stop control region of each high-temperature regenerator in the previous and next stages There is a feature that fluctuations in the heating amount due to can be removed.

また、上記の直列させる際に、前段の高温再生器による加熱量を、次段の発停制御領域の加熱容量に相当する加熱量だけ低減した後に、前段の高温再生器の比例制御による加熱量によって再び増加させる加熱と、次段の高温再生器の比例制御領域による加熱とを直列させているため、次段の発停制御領域の加熱容量の重なり部分による加熱量の急増を無くするとともに、装置の省エネルギー運転を行い得るなどの特長がある。   In addition, when the above-mentioned series is reduced, the heating amount by the high-temperature regenerator in the previous stage is reduced by the heating amount corresponding to the heating capacity in the start / stop control region of the next stage, and then the heating amount by proportional control of the high-temperature regenerator in the previous stage Because the heating increased again by the heating and the heating by the proportional control region of the next-stage high-temperature regenerator are connected in series, the sudden increase in the heating amount due to the overlapping portion of the heating capacity of the next-stage start / stop control region is eliminated, There are features such as energy-saving operation of the equipment.

この発明を実施するための最良の形態とする構成を図１〜図６の実施例１〜実施例３などによって説明する。なお、図１〜図６の構成において、図７〜図９の構成と同一符号で示す部分は、図７〜図９により説明した同一符号の部分と同一の機能をもつ部分であり、制御部３０は図８の制御部３０を用いて構成してある。   The best mode for carrying out the present invention will be described with reference to the first to third embodiments shown in FIGS. 1 to 6, the parts denoted by the same reference numerals as those in FIGS. 7 to 9 are parts having the same functions as the parts having the same reference numerals described with reference to FIGS. 30 is configured using the control unit 30 of FIG.

以下、図１〜図３により実施例１を説明する。なお、この実施例１は、上記の第１従来技術の構成、すなわち、冷水供給型の吸収式冷凍装置１００、または、上記の第２従来技術の構成、すなわち、冷温水切換供給型の吸収式冷凍装置１００に、この発明を適用して構成したものなので、上記の第１従来技術の構成に適用した場合には、管路１８・管路１９・開閉弁Ｖ５・開閉弁Ｖ６が無く、上記の第２従来技術の構成に適用した場合には、これらが設けてあるものとする。   The first embodiment will be described below with reference to FIGS. The first embodiment has the configuration of the first prior art, that is, the cold water supply type absorption refrigeration apparatus 100, or the configuration of the second prior art, that is, the cold / hot water switching supply type absorption type. Since the present invention is applied to the refrigeration apparatus 100, when applied to the configuration of the first prior art, there is no pipe 18, pipe 19, on-off valve V5, on-off valve V6. These are assumed to be provided when applied to the configuration of the second prior art.

そして、この実施例１の構成が、上記の第１従来技術の構成、または、第２従来技術の構成と異なる箇所は、次の箇所である。つまり、図１において、第１には、複数の高温再生器として、例えば、前段の高温再生器１ｗと、次段の高温再生器１とを設けることにより、冷水または温水に対する熱供給の熱容量、すなわち、熱負荷に対する熱容量を増大させた箇所である。   And the location where the structure of this Example 1 differs from the structure of said 1st prior art or the structure of 2nd prior art is the following location. That is, in FIG. 1, first, as a plurality of high-temperature regenerators, for example, by providing a high-temperature regenerator 1w in the previous stage and a high-temperature regenerator 1 in the next stage, the heat capacity of heat supply to cold water or hot water, That is, it is a place where the heat capacity for the heat load is increased.

第２には、数の高温再生器を直列に接続するために、前段の高温再生器１ｗの吸収液１ａｗと冷媒蒸気１ｂｗとを次段の高温再生器１に与えるように、前段の高温再生器１ｗの吸収液１ａｗ・１ｃｗを管路１０ｗで次段の高温再生器１の吸収液１ａの部分に導くとともに、前段の高温再生器1ｗの冷媒蒸気１ｂｗを管路１４ｗで次段の高温再生器１の冷媒蒸気１ｂの部分に導くように構成した箇所である。   Second, in order to connect several high-temperature regenerators in series, the high-temperature regenerator of the previous stage is supplied so that the absorbent 1aw and the refrigerant vapor 1bw of the high-temperature regenerator 1w of the previous stage are supplied to the high-temperature regenerator 1 of the next stage. The absorbents 1aw and 1cw of the regenerator 1w are guided to the absorbent 1a portion of the high-temperature regenerator 1 of the next stage through the pipe line 10w, and the refrigerant vapor 1bw of the high-temperature regenerator 1w of the front stage is regenerated at the high temperature stage of the next stage through the line 14w. It is the location comprised so that it might guide to the part of the refrigerant | coolant vapor | steam 1b of the container 1. FIG.

第３には、吸収液の流れを容易にするために、前段の高温再生器１ｗにおける吸収液１ａｗの液面レベルを次段の高温再生器１における吸収液１ａの液面レベルよりも高くする落差、例えば、落差Ｈを設けて配置した箇所である。   Thirdly, in order to facilitate the flow of the absorbing liquid, the liquid level of the absorbing liquid 1aw in the preceding high-temperature regenerator 1w is set higher than the liquid level of the absorbing liquid 1a in the following high-temperature regenerator 1. This is a place where a head, for example, a head H is provided.

第４には、図１・図２のように、前段の高温再生器１ｗの加熱量の加熱増加から、次段の高温再生器１の加熱量の加熱増加への移行を容易にするために、前段の高温再生器１ｗの熱容量βを小さく、次段の高温再生器１の熱容量αを大きく、例えば、図２のように、前段の高温再生器１ｗの熱容量βを次段の高温再生器１の熱容量αの１／２にして構成した箇所である。   Fourth, as shown in FIGS. 1 and 2, in order to facilitate the transition from the increased heating amount of the high-temperature regenerator 1w in the previous stage to the increased heating amount of the high-temperature regenerator 1 in the next stage. The heat capacity β of the preceding stage high-temperature regenerator 1w is reduced and the heat capacity α of the next stage high-temperature regenerator 1 is increased. For example, as shown in FIG. 2, the heat capacity β of the preceding stage high-temperature regenerator 1w is increased to the next stage high-temperature regenerator. This is a portion configured to be 1/2 of the heat capacity α of 1.

なお、この発明において、加熱量の増加とは、図２のように、前段の高温再生器１ｗの加熱容量βに対する加熱量％と、次段の高温再生器１の加熱容量αに対する加熱量％とを増加させることを言うものであり、具体的には、前段の高温再生器１ｗでは、燃料制御弁Ｖ２１ｗの弁開度ηを増加させ、また、次段の高温再生器１では、燃料制御弁Ｖ２１の弁開度γを増加させるものである。   In the present invention, the increase in the heating amount is, as shown in FIG. 2, the heating amount% with respect to the heating capacity β of the preceding high-temperature regenerator 1 w and the heating amount% with respect to the heating capacity α of the next-stage high-temperature regenerator 1. Specifically, in the high temperature regenerator 1w of the previous stage, the valve opening η of the fuel control valve V21w is increased, and in the high temperature regenerator 1 of the next stage, the fuel control is performed. The valve opening γ of the valve V21 is increased.

また、次段の高温再生器１は、図７により説明した第１従来技術・第２従来技術の構成における高温再生器１と同様の構成のものであり、前段の高温再生器１ｗの各部の構成は、高温再生器１の各部の符号と同じ符号の末尾にｗの文字を追加して記載したように、高温再生器１の各部の同様の機能をもつ構成であって、各構成部分の容量を小さくしたもので構成してある。   The next-stage high-temperature regenerator 1 has the same configuration as the high-temperature regenerator 1 in the configuration of the first and second prior arts described with reference to FIG. The structure is a structure having the same function of each part of the high-temperature regenerator 1 as described by adding the letter w to the end of the same reference numeral as that of each part of the high-temperature regenerator 1. It is configured with a smaller capacity.

第５には、図３のように、前段の高温再生器１ｗにおける発停制御領域Ｘを超えた比例制御領域Ｙによる加熱量の範囲と、次段の高温再生器１における発停制御領域Ｘを超えた比例制御領域Ｙによる加熱量の範囲とを直列させて熱供給を行わせるようにした直列加熱動作を行う構成とすることにより、前段の高温再生器１ｗにおける発停制御領域Ｘと次段の高温再生器１における発停制御領域Ｘとによる加熱量の変動を除去し得るように構成した箇所である。
なお、図３において、各加熱量の％値を示す数値は、図３の◆備考に記載した値である。 Fifthly, as shown in FIG. 3, the range of the heating amount by the proportional control region Y exceeding the start / stop control region X in the preceding high-temperature regenerator 1w, and the start / stop control region X in the next-stage high-temperature regenerator 1 By setting the series heating operation in such a manner that the heat supply is performed in series with the range of the heating amount by the proportional control region Y exceeding the start / stop control region X in the preceding high-temperature regenerator 1w, This is a portion configured to be able to remove the fluctuation of the heating amount due to the start / stop control region X in the high temperature regenerator 1 of the stage.
In addition, in FIG. 3, the numerical value which shows the% value of each heating amount is the value described in <Note> of FIG.

ここで、上記の直列加熱動作を行わせるための構成は、図３のように、前段の高温再生器１ｗの比例制御開始点Ｙ１を次段の高温再生器１の発停制御領域Ｘの開始点、すなわち、加熱量０％の位置を一致させた組合せ位置から、次段の高温再生器１の加熱量０％の位置を前段の高温再生器１ｗの比例制御領域Ｙの線に沿って斜め上方にずらせてゆき、次段の高温再生器１の比例制御開始点Ｙ１が前段の高温再生器１ｗの比例制御領域Ｙの最高点、すなわち、加熱量１００％と一致するまでの範囲での組合せが可能なわけである。   Here, the configuration for performing the above-described series heating operation is as shown in FIG. 3 in which the proportional control start point Y1 of the high-temperature regenerator 1w in the previous stage is set to the start / stop control region X of the high-temperature regenerator 1 in the next stage. From the point, that is, the combined position where the positions of the heating amount of 0% are made coincident, the position of the heating amount of 0% of the next stage high temperature regenerator 1 is slanted along the line of the proportional control region Y of the preceding stage high temperature regenerator 1w Shifting upward, combination in the range until the proportional control start point Y1 of the high temperature regenerator 1 of the next stage coincides with the highest point of the proportional control region Y of the high temperature regenerator 1w of the previous stage, that is, the heating amount 100%. Is possible.

また、こうした組合せ状態のままでは、重なり部分δの範囲で、前段の高温再生器１ｗによる加熱と、次段の高温再生器１による加熱とが重畳することになるため、直列加熱動作の移行点φ、すなわち、次段の高温再生器１の比例制御開始点Ｙ１に移行した点から前段の高温再生器１ｗの加熱量１００％の点まで間では、加熱量が急増して、図３の実質的な加熱増加量εのように、段違い状の部分をもつ加熱特性になってしまうわけである。   Further, in such a combined state, the heating by the high-temperature regenerator 1w in the previous stage and the heating by the high-temperature regenerator 1 in the next stage overlap in the range of the overlapping portion δ. The amount of heating increases rapidly from φ, that is, from the point of transition to the proportional control start point Y1 of the next-stage high-temperature regenerator 1 to the point where the heating amount of the preceding high-temperature regenerator 1w is 100%. Thus, a heating characteristic having a stepped portion is obtained as in the case of a typical heating increase amount ε.

したがって、必要に応じて、こうした重なり部分δでの加熱量の重畳分を修正する構成として、例えば、移行点φで、前段の高温再生器１ｗの加熱量％を、次段の高温再生器１の発停制御領域Ｘの加熱容量、すなわち、次段の高温再生器１の加熱量２５％に相当する加熱量だけ低減させた後に、次段の高温再生器１の加熱量１００％に相当する点までの間では、前段の高温再生器１ｗの加熱量％のみで加熱量を増加させてから、次段の高温再生器１の発停制御領域Ｘの加熱量％による加熱量の増加を行うように構成することができる。   Therefore, if necessary, as a configuration for correcting the superposition of the heating amount at the overlapping portion δ, for example, at the transition point φ, the heating amount% of the preceding high temperature regenerator 1w is changed to the next high temperature regenerator 1. The heating capacity of the start / stop control region X, that is, the heating amount corresponding to 25% of the heating amount of the next stage high temperature regenerator 1 is reduced, and then the heating amount of the next stage high temperature regenerator 1 is equivalent to 100%. Up to the point, the heating amount is increased only by the heating amount% of the high-temperature regenerator 1w in the previous stage, and then the heating amount is increased by the heating amount% of the start / stop control region X of the high-temperature regenerator 1 in the next stage. It can be constituted as follows.

こうした修正を行えば、図３の修正後の加熱増加量ωのように、次段の高温再生器１の比例制御開始点Ｙ１を延長させて、全体の加熱容量を（α＋β）まで増加できることになる。   By making such correction, the overall heating capacity can be increased to (α + β) by extending the proportional control start point Y1 of the high-temperature regenerator 1 of the next stage, as in the heating increase amount ω after correction in FIG. Become.

以下、図４により実施例２を説明する。この実施例２の構成が上記の実施例１の構成と異なる箇所は、実施例１で述べた移行点φを加熱増加方向にずらせて、次段の高温再生器１の比例制御開始点Ｙ１が前段の高温再生器１ｗの比例制御領域Ｙの最高点、すなわち、加熱量１００％と一致するように構成した箇所である。   The second embodiment will be described below with reference to FIG. The difference between the configuration of the second embodiment and the configuration of the first embodiment is that the transition point φ described in the first embodiment is shifted in the heating increasing direction so that the proportional control start point Y1 of the next-stage high-temperature regenerator 1 is This is a portion configured to coincide with the highest point of the proportional control region Y of the high-temperature regenerator 1w in the preceding stage, that is, the heating amount 100%.

したがって、実質的な加熱増加量εは、図４のようになり、移行時における加熱量の急増は、重なり部分δの加熱量のみになるが、重なり部分δでの加熱量の重畳分を修正する構成は、例えば、実施例１の場合と同様に行えばよいことになり、また、修正後の加熱増加量ωも同様に、次段の高温再生器１の比例制御開始点Ｙ１を延長させて、全体の加熱容量を（α＋β）まで増加できることになるわけである。   Therefore, the substantial heating increase amount ε is as shown in FIG. 4, and the rapid increase in the heating amount at the time of transition is only the heating amount of the overlapping portion δ, but the overlapping amount of the heating amount in the overlapping portion δ is corrected. The configuration to be performed may be performed in the same manner as in the first embodiment, for example, and the heating increase amount ω after correction is similarly extended by extending the proportional control start point Y1 of the high-temperature regenerator 1 of the next stage. Thus, the total heating capacity can be increased to (α + β).

以下、図５・図６・図８により実施例３を説明する。この実施例３の構成は、直列加熱動作の移行構成を上記の実施例２と同様の移行構成とし、重なり部分δの加熱量の修正を制御部３０によって行うように構成したものである。
なお、図５において、各加熱量の％値を示す数値は、図５の◆備考に記載した値である。 The third embodiment will be described below with reference to FIGS. In the configuration of the third embodiment, the transition configuration of the series heating operation is the same as the transition configuration of the second embodiment, and the heating amount of the overlapping portion δ is corrected by the control unit 30.
In addition, in FIG. 5, the numerical value which shows% value of each heating amount is the value described in the remarks of FIG.

ここで、図８の制御部３０によって、図５の〔直列加熱動作の加熱特性〕による加熱動作に移行するまでの動作を説明すると、まず、前段の高温再生器１ｗと次段の高温再生器１との運転を起動させ、各高温再生器の温度検出器Ｔ１・Ｔ１ｗが所定の温度、例えば、１００℃になり、各高温再生器の液面検出器Ｅ１・Ｅ１ｗによって、吸収液1ｃ・1ｃｗの液面が所定のレベルに保たれ、各部の気圧差によって、吸収液1ｃ・1ｃｗが、それぞれ、下流側に流動し得る状態になり、起動が完了した後に、図６の制御処理フローにもとづく定常制御の処理が行われるように構成したものである。   Here, the operation until the control unit 30 in FIG. 8 shifts to the heating operation according to [heating characteristics of series heating operation] in FIG. 5 will be described. First, the high-temperature regenerator 1w in the previous stage and the high-temperature regenerator in the next stage. 1 is started, the temperature detectors T1 and T1w of each high temperature regenerator reach a predetermined temperature, for example, 100 ° C., and the liquid level detectors E1 and E1w of each high temperature regenerator allow the absorbing liquids 1c and 1cw. The liquid level is kept at a predetermined level, and the absorption liquids 1c and 1cw can flow downstream due to the pressure difference between the respective parts. After the start-up is completed, the control process flow of FIG. In this configuration, steady control processing is performed.

そして、制御部３０は、作業用メモリ３３に取り込んだ各部の検出データと、データ用メモリ３４に予め記憶した前段の高温再生器１ｗと次段の高温再生器１との各比例制御開始点Ｙ１などの各データとにもとづいて、処理用メモリ３２に予め記憶した図６の制御処理フローのプログラムによって、所要の動作を行うように構成してある。   Then, the control unit 30 detects each part of the detection data fetched into the work memory 33, and each proportional control start point Y1 between the previous high-temperature regenerator 1w and the next high-temperature regenerator 1 stored in the data memory 34 in advance. On the basis of the data such as the above, a required operation is performed by the program of the control processing flow of FIG. 6 stored in advance in the processing memory 32.

以下、図６の制御処理フローについて説明する。この制御処理フローは、例えば、装置全体の制御処理を行うメイン処理フローのサブルーチンとして構成されており、例えば、上記の起動が完了した旨のデータ信号、または、入力操作部分３６に設けた所定の操作キーを操作した旨のデータ信号を「定常運転移行データ」として、図６の制御処理フローによる動作が行われるように構成してある。   Hereinafter, the control processing flow of FIG. 6 will be described. This control processing flow is configured as, for example, a subroutine of a main processing flow for performing control processing for the entire apparatus. For example, a data signal indicating that the activation has been completed or a predetermined signal provided in the input operation portion 36 is configured. A data signal indicating that the operation key has been operated is set as “steady operation transition data”, and the operation according to the control processing flow of FIG. 6 is performed.

また、加熱動作の目標とする「加熱量データ」は、図１の冷水２２ａまたは温水２２ａに対する目標温度として入力操作部分３６により設定した設定温度値のデータと、この設定温度値と冷水２２ａまたは温水２２ａの現在温度、すなわち、温度検出器ＴＤ２の温度ｔ２との温度差に対応して予め実験的に定められ、データ用メモリ３４に予め記憶した加熱量のデータとを含むデータで構成してある。   Further, the “heating amount data” that is the target of the heating operation includes the data of the set temperature value set by the input operation portion 36 as the target temperature for the cold water 22a or the hot water 22a in FIG. 1, and the set temperature value and the cold water 22a or the hot water. 22a, that is, data including heating amount data that is experimentally determined in advance corresponding to the temperature difference from the temperature t2 of the temperature detector TD2 and stored in the data memory 34 in advance. .

具体的には、図６の制御処理フローにおいて、
◆ステップＳＰ１では、運転データを取り込んで次のステップＳＰ２に移行する。
◆ステップＳＰ２では、運転データが「定常運転移行データ」であるか否かを判別する。「定常運転移行データ」であるときは、次のステップＳＰ３に移行し、そうでないときはメイン処理フローの所定のステップ箇所に移行する。 Specifically, in the control processing flow of FIG.
◆ In step SP1, the operation data is taken and the process proceeds to the next step SP2.
In step SP2, it is determined whether or not the operation data is “steady operation transition data”. If it is “steady operation transition data”, the process proceeds to the next step SP3, and if not, the process proceeds to a predetermined step in the main process flow.

◆ステップＳＰ３では、「加熱量データ」を取り込んで、次のステップＳＰ４に移行する。
◆ステップＳＰ４では、加熱量を前段の高温再生器１ｗの比例制御開始点Ｙ１の加熱量にして次のステップＳＰ５に移行する。
◆ステップＳＰ５では、加熱量と温度検出器ＴＤ２の温度ｔ２とが「加熱量データ」の値、すなわち、目標値になっているか否かを判別する。目標値になっているときは、メイン処理フローの所定のステップ箇所に移行し、そうでないときは次のステップＳＰ６に移行する。
なお、以後は、所定時間、例えば、１０秒毎に、ステップＳＰ１に移行してくる。ステップＳＰ７・ＳＰ１１・ＳＰ１４・ＳＰ１６の場合も同様である。 In step SP3, “heating amount data” is fetched, and the process proceeds to the next step SP4.
In step SP4, the heating amount is set to the heating amount at the proportional control start point Y1 of the high-temperature regenerator 1w in the previous stage, and the process proceeds to the next step SP5.
In step SP5, it is determined whether or not the heating amount and the temperature t2 of the temperature detector TD2 are the “heating amount data” value, that is, the target value. When the target value is reached, the routine proceeds to a predetermined step in the main process flow, and when it is not, the routine proceeds to the next step SP6.
Thereafter, the process proceeds to step SP1 every predetermined time, for example, every 10 seconds. The same applies to steps SP7, SP11, SP14, and SP16.

◆ステップＳＰ６では、加熱量を前段の高温再生器１ｗの比例制御領域Ｙの加熱量にして次のステップＳＰ７に移行する。
ここで、このステップに、再びきたときには、その都度、比例制御領域Ｙの加熱量を漸増させるように処理するものとする。
◆ステップＳＰ７では、ステップＳＰ５と同様の処理を行い、目標値になっているときは、メイン処理フローの所定のステップ箇所に移行し、そうでないときは次のステップＳＰ８に移行する。 In step SP6, the heating amount is set to the heating amount in the proportional control region Y of the high-temperature regenerator 1w in the previous stage, and the process proceeds to the next step SP7.
Here, each time this step comes again, processing is performed so as to gradually increase the heating amount of the proportional control region Y.
In step SP7, the same process as in step SP5 is performed. When the target value is reached, the process proceeds to a predetermined step in the main process flow. Otherwise, the process proceeds to the next step SP8.

◆ステップＳＰ８では、加熱量が前段の高温再生器１ｗの比例制御領域Ｙの最高値、すなわち、１００％に達しているか否かを判別する。１００％に達しているときは、次のステップＳＰ９に移行し、そうでないときはステップＳＰ６に移行する。
◆ステップＳＰ９では、加熱量を次段の高温再生器１の比例制御開始点Ｙ１の加熱量にするとともに、所定の低減量、すなわち、前段の高温再生器１ｗの加熱量を次段の高温再生器１の発停制御領域Ｘの加熱容量に相当する加熱量だけ低減した後に、次のステップＳＰ１０に移行する。 In step SP8, it is determined whether or not the heating amount has reached the maximum value of the proportional control region Y of the preceding high-temperature regenerator 1w, that is, 100%. When it reaches 100%, the process proceeds to the next step SP9, and when not, the process proceeds to step SP6.
In step SP9, the heating amount is set to the heating amount at the proportional control start point Y1 of the next-stage high-temperature regenerator 1, and the predetermined reduction amount, that is, the heating amount of the preceding-stage high-temperature regenerator 1w is changed to the next-stage high-temperature regeneration. After the heating amount corresponding to the heating capacity of the start / stop control region X of the vessel 1 is reduced, the process proceeds to the next step SP10.

◆ステップＳＰ１０では、ステップＳＰ６と同様に、加熱量を前段の高温再生器１ｗの比例制御領域Ｙの加熱量にして次のステップＳＰ１１に移行する。
ここで、このステップに、再びきたときには、その都度、比例制御領域Ｙの加熱量を増させるように処理するものとする。
◆ステップＳＰ１１では、ステップＳＰ５と同様の処理を行い、目標値になっているときは、メイン処理フローの所定のステップ箇所に移行し、そうでないときは次のステップＳＰ１２に移行する。 In step SP10, as in step SP6, the heating amount is set to the heating amount in the proportional control region Y of the high-temperature regenerator 1w in the previous stage, and the process proceeds to the next step SP11.
Here, each time this step comes again, processing is performed to increase the heating amount of the proportional control region Y each time.
In step SP11, the same process as in step SP5 is performed. When the target value is reached, the process proceeds to a predetermined step in the main process flow. Otherwise, the process proceeds to the next step SP12.

◆ステップＳＰ１２では、ステップＳＰ８と同様の処理を行い、１００％に達しているときは、次のステップＳＰ１３に移行し、そうでないときはステップＳＰ１０に移行する。
◆ステップＳＰ１３では、加熱量を次段の高温再生器１の比例制御開始点Ｙ１の加熱量にした後に、次のステップＳＰ１４に移行する。
◆ステップＳＰ１４では、ステップＳＰ５と同様の処理を行い、目標値になっているときは、メイン処理フローの所定のステップ箇所に移行し、そうでないときは次のステップＳＰ１５に移行する。 In step SP12, the same processing as in step SP8 is performed. When 100% is reached, the process proceeds to the next step SP13, and otherwise, the process proceeds to step SP10.
In step SP13, after the heating amount is set to the heating amount at the proportional control start point Y1 of the high-temperature regenerator 1 at the next stage, the process proceeds to the next step SP14.
In step SP14, the same process as in step SP5 is performed. When the target value is reached, the process proceeds to a predetermined step in the main process flow. Otherwise, the process proceeds to the next step SP15.

◆ステップＳＰ１５では、加熱量を次段の高温再生器１の比例制御領域Ｙの加熱量にして次のステップＳＰ１に移行する。
ここで、このステップに、再びきたときには、その都度、比例制御領域Ｙの加熱量を漸増させるように処理するものとする。
◆ステップＳＰ１６では、ステップＳＰ５と同様の処理を行い、目標値になっているときは、メイン処理フローの所定のステップ箇所に移行し、そうでないときは次のステップＳＰ１７に移行する。
なお、ステップＳＰ１８を経由した後に、このステップにきて、メイン処理フローの所定のステップ箇所に移行する際には、ステップＳＰ１８で行った表示を解除するように処理する。 In step SP15, the heating amount is set to the heating amount in the proportional control region Y of the next stage high temperature regenerator 1, and the process proceeds to the next step SP1.
Here, each time this step comes again, processing is performed so as to gradually increase the heating amount of the proportional control region Y.
In step SP16, the same process as in step SP5 is performed. When the target value is reached, the process proceeds to a predetermined step in the main process flow. Otherwise, the process proceeds to the next step SP17.
In addition, after passing through step SP18, when this step is entered and the process proceeds to a predetermined step in the main processing flow, processing is performed so as to cancel the display performed in step SP18.

◆ステップＳＰ１７では、加熱量が次段の高温再生器１の比例制御領域Ｙの最高値、すなわち、１００％に達しているか否かを判別する。１００％に達しているときは、次のステップＳＰ１８に移行し、そうでないときはステップＳＰ１５に移行する。
◆ステップＳＰ１８では、例えば、図８の表示部分３７に、加熱量が最高値の運転状態になっている旨の表示を行った後に、次のステップＳＰ１５に移行する。 In step SP17, it is determined whether or not the heating amount has reached the maximum value of the proportional control region Y of the next-stage high-temperature regenerator 1, that is, 100%. When it reaches 100%, the process proceeds to the next step SP18, and when not, the process proceeds to step SP15.
In step SP18, for example, a display indicating that the heating amount is in the maximum operating state is displayed on the display portion 37 of FIG. 8, and then the process proceeds to the next step SP15.

したがって、図５のように、次段の高温再生器１の「発停制御領域Ｘ」による動作部分が無くなるので、この発停動作による加熱量の変動がなくなるとともに、前段の高温再生器１ｗの「発停制御領域Ｘ」（２５％）の範囲が、全体の加熱容量（α＋β）、すなわち、この加熱容量全体を１つの高温再生器でした場合に比べて、実質的には、その１／３の８．３％の範囲に縮小されたことになり、この縮小による当該発停動作による加熱量の変動もなくなるわけである。   Therefore, as shown in FIG. 5, since the operation part by the “start / stop control region X” of the next-stage high-temperature regenerator 1 is eliminated, the heating amount does not fluctuate due to this start-stop operation, and the high-temperature regenerator 1w of the preceding stage disappears. The range of the “start / stop control region X” (25%) is substantially equal to 1 / of the entire heating capacity (α + β), that is, compared with the case where the entire heating capacity is a single high-temperature regenerator. Therefore, the heating amount is not changed by the start / stop operation due to the reduction.

ここで、複数の高温再生器を設ける構成を、例えば、３つ以上の高温再生器とする場合には、各高温再生器間の構成と動作を、上記の実施例１における前段の高温再生器１ｗと次段の高温再生器１と同様にして、順次に直列的に、接続構成するとともに、全ての高温再生器にわたって、図５・図６と同様の直列加熱動作を行わせるように構成すればよいわけである。   Here, when the configuration in which a plurality of high-temperature regenerators are provided is, for example, three or more high-temperature regenerators, the configuration and operation between the high-temperature regenerators are the same as those in the preceding stage in the first embodiment. In the same manner as 1w and the next-stage high-temperature regenerator 1, they are connected in series in series, and all the high-temperature regenerators are configured to perform the same series heating operation as in FIGS.
