解決しようとする課題は、加熱工程と冷却工程との交互の切り換え時に、熱エネルギー損失を極力小さくすることのできる加熱冷却装置を提供することである。   The problem to be solved is to provide a heating and cooling device capable of minimizing thermal energy loss when switching between a heating process and a cooling process alternately.

本発明は、被熱交換物を加熱あるいは冷却する熱交換室を形成して、当該熱交換室に熱交換流体を供給する熱交換流体供給管を接続し、熱交換室を吸引手段と接続したものにおいて、吸引手段をエゼクタとタンクと循環ポンプで構成して、当該タンク内の流体と熱交換してタンク内流体の保有する熱量を蓄熱すると共に、タンク内流体温度が低い場合は、タンク内の低温流体と熱交換して所定の温度まで上昇させる、蓄熱タンクを配置したものである。 In the present invention, a heat exchange chamber for heating or cooling a heat exchange object is formed, a heat exchange fluid supply pipe for supplying a heat exchange fluid to the heat exchange chamber is connected, and the heat exchange chamber is connected to a suction means. If the suction means is composed of an ejector, a tank and a circulation pump, heat is exchanged with the fluid in the tank to store the amount of heat held by the fluid in the tank, and if the tank fluid temperature is low, The heat storage tank is arranged to exchange heat with the low-temperature fluid and raise the temperature to a predetermined temperature .

本発明の加熱冷却装置は、吸引手段のタンク内流体の保有する熱量を蓄熱する蓄熱タンクを配置したことにより、蓄熱タンクに所定の熱量が蓄熱されていない場合は、吸引手段のタンク内の高温流体と熱交換して蓄熱タンクへ所定の熱量を蓄熱することができ、一方、蓄熱タンクが所定の熱量を蓄熱しており、吸引手段のタンク内流体温度が低い場合は、タンク内の低温流体と熱交換して所定の温度まで上昇させることにより、熱エネルギーの有効利用を図ることができる。   The heating / cooling device of the present invention has a high temperature in the tank of the suction unit when a predetermined amount of heat is not stored in the heat storage tank by arranging a heat storage tank that stores the amount of heat held by the fluid in the tank of the suction unit. The heat storage tank can store a predetermined amount of heat by exchanging heat with the fluid. On the other hand, when the heat storage tank stores a predetermined amount of heat and the temperature of the fluid in the tank of the suction means is low, the low-temperature fluid in the tank The heat energy can be effectively utilized by exchanging heat and increasing the temperature to a predetermined temperature.

本発明は、吸引手段のタンク内流体の保有する熱量を蓄熱する蓄熱タンクを設けたものであるが、この蓄熱タンクは、吸引手段のタンク内流体の保有する熱量に応じて、１台あるいは複数台を配置することができる。   The present invention is provided with a heat storage tank that stores the amount of heat held by the fluid in the tank of the suction means. One or a plurality of the heat storage tanks are provided depending on the amount of heat held by the fluid in the tank of the suction means. A stand can be placed.

本実施例においては、熱交換室として反応釜１のジャケット部２を用いた例を示す。反応釜１の内部に入れた図示しない被熱交換物を、ジャケット部２に供給する加熱源としての加熱流体、あるいは、冷却源としての冷却流体によって熱交換するものである。   In the present embodiment, an example in which the jacket portion 2 of the reaction kettle 1 is used as a heat exchange chamber is shown. Heat exchange material (not shown) placed in the reaction kettle 1 is heat exchanged by a heating fluid as a heating source supplied to the jacket portion 2 or a cooling fluid as a cooling source.

反応釜１のほぼ全周にわたりジャケット部２を形成して、このジャケット部２に吸引手段としての組み合わせ真空ポンプ４と、加熱流体としての蒸気供給管８、及び、冷却流体供給管５を接続する。   A jacket portion 2 is formed over almost the entire circumference of the reaction kettle 1, and a combined vacuum pump 4 as a suction means, a steam supply pipe 8 as a heating fluid, and a cooling fluid supply pipe 5 are connected to the jacket portion 2. .

ジャケット部２の左側上部には、流量調節弁７を介在した蒸気供給管８を接続する。この蒸気供給管８から、所定圧力すなわち所定温度の加熱用蒸気が、ジャケット部２へ供給されることによって、反応釜１内の被加熱物を加熱することができるものである。   A steam supply pipe 8 with a flow rate adjusting valve 7 interposed is connected to the upper left portion of the jacket part 2. By supplying steam for heating at a predetermined pressure, that is, a predetermined temperature from the steam supply pipe 8 to the jacket portion 2, an object to be heated in the reaction kettle 1 can be heated.

ジャケット部２の下方に排出管９を接続して、組み合わせ真空ポンプ４のエゼクタ１０と接続する。排出管９には、開閉弁１１と蒸気トラップ１２をそれぞれ並列に取り付ける。蒸気トラップ１２は、排出管９から流下してくる蒸気と凝縮水としての復水の混合流体から復水だけを排出して蒸気は排出しないものであり、排出された復水は下方のエゼクタ１０に吸引される。   A discharge pipe 9 is connected below the jacket portion 2 and connected to the ejector 10 of the combination vacuum pump 4. An open / close valve 11 and a steam trap 12 are attached to the discharge pipe 9 in parallel. The steam trap 12 discharges only condensate from the mixed fluid of steam flowing down from the discharge pipe 9 and condensate as condensed water, and does not discharge steam. The discharged condensate is discharged from the lower ejector 10. Sucked into.

組み合わせ真空ポンプ４を、エゼクタ１０とタンク１３と循環ポンプ１４を順次に循環路１５で連通して形成する。タンク１３の上部には、冷却流体としての冷却水を補給する冷却水補給管１６を接続する。循環路１５の一部を分岐して余剰水排出管１７を接続する。   The combination vacuum pump 4 is formed by sequentially communicating the ejector 10, the tank 13, and the circulation pump 14 through the circulation path 15. A cooling water supply pipe 16 for supplying cooling water as a cooling fluid is connected to the upper portion of the tank 13. A part of the circulation path 15 is branched and the surplus water discharge pipe 17 is connected.

タンク１３の左側に蓄熱タンク３を配置する。蓄熱タンク３内には図示はしないが蓄熱材としての水や熱媒などを溜め置く。蓄熱タンク３の内部とタンク１３の内部を熱交換パイプ６で連通する。蓄熱タンク３内の蓄熱材を熱交換パイプ６へ通過させることによって、タンク１３内の流体の保有する熱量を蓄熱材で吸収して蓄熱タンク３へ蓄熱したり、あるいは反対に、蓄熱タンク３内の保有熱を熱交換パイプ６を介してタンク１３内の流体へ伝熱することができるものである。 The heat storage tank 3 is disposed on the left side of the tank 13. Although not shown in the figure, the heat storage tank 3 stores water or a heat medium as a heat storage material. The inside of the heat storage tank 3 and the inside of the tank 13 are connected by a heat exchange pipe 6. By passing the heat storage material in the heat storage tank 3 to the heat exchange pipe 6, the amount of heat held by the fluid in the tank 13 is absorbed by the heat storage material and stored in the heat storage tank 3. Can be transferred to the fluid in the tank 13 via the heat exchange pipe 6.

蓄熱タンク３の右側上部には、蓄熱タンク３内へ蓄熱材を補給する蓄熱材補給管１８を接続する。また、蓄熱タンク３の上下には、蓄熱材を補助的に加熱したりあるいは冷却するための熱交換流体供給管１９と熱交換流体排出管２０をそれぞれ接続する。 A heat storage material supply pipe 18 for supplying heat storage material into the heat storage tank 3 is connected to the upper right side of the heat storage tank 3. In addition, a heat exchange fluid supply pipe 19 and a heat exchange fluid discharge pipe 20 are connected to the upper and lower sides of the heat storage tank 3 to supplementarily heat or cool the heat storage material.

反応釜1内の被加熱物を加熱する場合は、蒸気供給管８から加熱に適した温度の蒸気をジャケット部２へ供給することによって、蒸気が反応釜1内の被加熱物に熱を与えて加熱する。加熱により蒸気の凝縮した復水と一部の蒸気は排出管９を通り蒸気トラップ１２から復水だけがエゼクタ１０に吸引されタンク１３に至る。 When heating the object to be heated in the reaction vessel 1, the steam supplies heat to the object to be heated in the reaction vessel 1 by supplying steam at a temperature suitable for heating from the steam supply pipe 8 to the jacket portion 2. Heat. Condensate condensed with steam by heating and part of the steam pass through the discharge pipe 9 and only the condensate is sucked into the ejector 10 from the steam trap 12 and reaches the tank 13.

一方、組み合わせ真空ポンプ４の循環ポンプ１４を駆動して、エゼクタ１０の発生する吸引力で排出管９を介してジャケット部２内を所定の圧力状態、例えば、大気圧以下の真空状態、とすることにより、１００℃以下の温度の蒸気で反応釜１を加熱することがでまる。 On the other hand, the circulation pump 14 of the combination vacuum pump 4 is driven, and the inside of the jacket portion 2 is brought into a predetermined pressure state, for example, a vacuum state below atmospheric pressure, through the discharge pipe 9 by the suction force generated by the ejector 10. Thus, the reaction kettle 1 can be heated with steam having a temperature of 100 ° C. or lower.

タンク１３内に復水が流入するにつれてタンク１３内の流体温度が上昇する。タンク１３内の流体温度が所定値以上に上昇すると、熱交換パイプ６を介して蓄熱材をタンク１３内へ供給して、タンク１３の余剰熱を吸収する。吸収した熱量は、蓄熱タンク３内の蓄熱材に蓄熱される。   As the condensate flows into the tank 13, the fluid temperature in the tank 13 increases. When the fluid temperature in the tank 13 rises to a predetermined value or more, the heat storage material is supplied into the tank 13 through the heat exchange pipe 6 and the excess heat in the tank 13 is absorbed. The absorbed heat is stored in the heat storage material in the heat storage tank 3.

反応釜１を加熱から冷却へと切り換える場合は、蒸気供給管８からの蒸気の供給を停止すると共に、冷却流体供給管５から冷却流体をジャケット部２へ供給することによって、ジャケット部２内は大気圧以下の真空状態であり、冷却流体が反応釜１の熱を奪って直ちに蒸発気化することによって反応釜１を気化冷却する。この場合、タンク１３内の流体温度は、熱交換パイプ６によって熱交換され所定温度まで低下しているために、加熱から冷却への切り換えを時間遅れなく行うことができる。   When the reaction kettle 1 is switched from heating to cooling, the supply of steam from the steam supply pipe 8 is stopped, and the cooling fluid is supplied from the cooling fluid supply pipe 5 to the jacket part 2 so that the inside of the jacket part 2 is It is a vacuum state below atmospheric pressure, and the reaction fluid 1 is vaporized and cooled by evaporating and evaporating immediately after the cooling fluid takes heat of the reaction vessel 1. In this case, since the fluid temperature in the tank 13 is heat-exchanged by the heat exchange pipe 6 and lowered to a predetermined temperature, switching from heating to cooling can be performed without time delay.

さらに、反応釜１を冷却から加熱へと切り換える場合は、蓄熱タンク３に蓄熱していた熱量を熱交換パイプ６を介してタンク１３内の流体へ伝熱することによって、タンク１３内の流体温度を加熱に適した温度まで上昇させてから加熱工程へと切り換えることができる。   Further, when the reaction kettle 1 is switched from cooling to heating, the amount of heat stored in the heat storage tank 3 is transferred to the fluid in the tank 13 through the heat exchange pipe 6, so that the fluid temperature in the tank 13 is increased. Can be raised to a temperature suitable for heating before switching to the heating step.

このように、蓄熱タンク３に所定の熱量を蓄熱しておき、加熱工程への切り換え時に使用することによって、熱エネルギーの有効利用を図ることができる。   Thus, the thermal energy can be effectively utilized by storing a predetermined amount of heat in the heat storage tank 3 and using it when switching to the heating process.
