Description

本発明は、地中熱や空気熱などの自然熱エネルギー又は人工排熱などの熱エネルギーにより、逆カルノーサイクル原理を利用して効率的に熱利用を図ることのできる装置に関するものである。   The present invention relates to an apparatus that can efficiently use heat by utilizing the inverse Carnot cycle principle by natural heat energy such as underground heat and air heat or heat energy such as artificial exhaust heat.
今日、逆カルノーサイクル原理を利用して製品化したヒートポンプを用い、地中熱や空気熱を利用して冷暖房を行なったり、生活排水の熱や工場排熱を利用して暖房や給湯を行うなど、自然熱エネルギーや廃熱エネルギーを利用して生活に必要な熱エネルギーとし、エネルギーを効果的に利用してエネルギーの無駄な消費を少なくする試みが種々行われている。   Today, heat pumps that have been commercialized using the reverse Carnot cycle principle are used to cool and heat using geothermal heat and air heat, and heating and hot water supply using heat from domestic wastewater and factory waste heat. Various attempts have been made to use natural heat energy and waste heat energy to obtain heat energy necessary for daily life, and to effectively use energy to reduce wasteful consumption of energy.
例えば、冷暖房用の空調機や温水給湯を行う給湯器を使用するに際し、住宅排水における水熱を主利用熱とすると共に地中熱を補助利用熱としてヒートポンプを使用し、温熱又は冷熱を取り出す装置の提案(特許文献1)がなされている。   For example, when using an air conditioner for air conditioning or a hot water heater that performs hot water hot water supply, a device that takes out the heat or cold by using a heat pump that uses the water heat in the house drainage as the main heat and uses the underground heat as the auxiliary heat. (Patent Document 1) has been made.
また、本件出願人は、地中熱を利用し、冷暖房や給湯を効果的に行うヒートポンプの提案(特許文献2)を行い、更に、太陽熱集熱パネルとヒートポンプとを組み合わせた給湯冷暖房システムであって、季節や天候による熱エネルギー量の変動が激しい太陽熱を効果的に利用可能とするシステムの提案(特許文献3)も行っている。   In addition, the present applicant has proposed a heat pump that effectively uses the underground heat for air conditioning and hot water supply (Patent Document 2), and further has a hot water supply air conditioning system that combines a solar heat collecting panel and a heat pump. In addition, a system (Patent Document 3) has also been proposed (PTL 3) that can effectively use solar heat, in which the amount of thermal energy varies greatly depending on the season and weather.
これらのヒートポンプは、逆カルノーサイクル原理を利用し、例えば「1」の電気エネルギーを投入して「2」以上の空気熱エネルギーを取り込み、「3」以上の熱エネルギーを取り出すことができるように設計され、近年では、「1」の電気エネルギーを投入して「5」以上の空気熱エネルギーを取り込み、「6」以上の熱エネルギーを計算上取り出すことができるようにされるものもある。   These heat pumps are designed to use the inverse Carnot cycle principle, for example, to input "1" electrical energy, capture "2" or higher air thermal energy, and extract "3" or higher thermal energy. In recent years, there have been some cases where electric energy of “1” is input to take in air thermal energy of “5” or more, and heat energy of “6” or more can be taken out in calculation.
特開2003―214722号公報Japanese Patent Laid-Open No. 2003-214722 特許第5067958号公報Japanese Patent No. 5067958 特開2015―052434号公報JP2015-052434A
しかし、ヒートポンプは、上述の様に、熱エネルギーを集めて効率良く熱エネルギーを取り出すことができるように設計され、実機の能力検査では、一定の試験環境において効率良くエネルギーを集めて無駄の極めて少ないエネルギーの取出しが可能となっていても、運転環境が一定しない現場では、ヒートポンプの著しい効率低下が生じることが多く、検査値の半分以下の熱エネルギーしか取り出せない場合も多々生じている。   However, the heat pump is designed to collect heat energy and efficiently extract heat energy as described above, and in the performance test of the actual machine, it collects energy efficiently in a certain test environment and has very little waste. Even if the energy can be extracted, the efficiency of the heat pump is often significantly reduced at the site where the operating environment is not constant, and there are many cases where only half or less of the inspection value can be extracted.
そして、今日、地中熱、空気熱、太陽熱などの自然エネルギーを使用して逆カルノーサイクル原理を利用して製品化されたヒートポンプにより冷暖房を行うことが多くなっているも、空気熱や太陽熱を利用する場合、季節や天候により温度(エネルギー量)の変化が大きく、ヒートポンプの効率も変動することとなり、エネルギーの利用効率を高めることが困難であった。   Nowadays, natural heat such as underground heat, air heat, and solar heat is used to heat and cool air using heat pumps that have been commercialized using the reverse Carnot cycle principle. When used, the temperature (energy amount) varies greatly depending on the season and weather, and the efficiency of the heat pump also fluctuates, making it difficult to increase the energy utilization efficiency.
即ち、空気熱を利用する場合、夏場に冷房を行うとき、外気温度が35℃以上となってヒートポンプの内部循環熱媒の温度を低下させる蒸発器を冷却するように室外機から送られる外部循環熱媒の温度が高く、外部循環熱媒による冷却効率が低下し、ひいてはヒートポンプから取り出す冷熱量が低下することが有り、また、冬場に暖房を行うとき、外気温度が氷点下となり、内部循環熱媒の温度を上昇させる凝縮器を加温するように室外機から送られる外部循環熱媒の温度が低く、内部循環熱媒の温度上昇が不十分となり、ヒートポンプから取り出す温熱量が低下する等、気温条件によって凝縮器や蒸発器の温度調整が目標値から大きく外れ、冷熱や温熱の取出し性能が低下する現状となっている。   That is, when using air heat, when cooling in summer, the outside air temperature is 35 ° C. or higher and the external circulation sent from the outdoor unit is cooled so as to cool the evaporator that lowers the temperature of the heat circulating internal heat medium of the heat pump. The temperature of the heat medium is high, the cooling efficiency of the external circulation heat medium is reduced, and the amount of cooling heat taken out from the heat pump may be reduced, and when heating in winter, the outside air temperature becomes below freezing point, and the internal circulation heat medium The temperature of the external circulation heat medium sent from the outdoor unit is low so as to heat the condenser that raises the temperature of the air, the temperature rise of the internal circulation heat medium becomes insufficient, the amount of heat extracted from the heat pump decreases, etc. Depending on the conditions, the temperature adjustment of the condenser and the evaporator greatly deviates from the target value, and the present condition is that the performance of taking out the cold and warm is lowered.
更に、空気熱を利用する場合、近年では、夏場の屋内冷房により生じた排熱を空気中に放出する空気熱利用ヒートポンプ冷暖房装置の使用量が都市部では増大し、排熱によるヒートアイランド現象が生じる問題も発生している。   Furthermore, in the case of using air heat, in recent years, the amount of use of air heat heat pump air conditioners that release exhaust heat generated by indoor cooling in the summer into the air has increased in urban areas, resulting in a heat island phenomenon due to exhaust heat. There are also problems.
また、地中熱は、比較的温度変化が小さく、一年を通じてヒートポンプの効率を変化(低下)させないようにすることが可能であるも、ヒートポンプを連続運転する場合、地中に埋設した熱交換パイプによる採熱温度が変化しないようにするためには、熱交換パイプを地中深く、且つ、広範囲に埋設する必要が有り、熱交換パイプの設置に手数と時間及び費用を要する欠点があった。   In addition, geothermal heat has a relatively small temperature change, and it is possible to prevent the heat pump efficiency from changing (decreasing) throughout the year. However, when the heat pump is operated continuously, heat exchange buried in the ground In order not to change the heat collection temperature by the pipe, it is necessary to embed the heat exchange pipe deeply and widely in the ground, and there is a drawback that it takes time, cost and labor to install the heat exchange pipe. .
そして、生活排水熱や工場排熱などの人工排熱を利用するに際しては、排熱温度が時間によって変化することが多く、従来型のヒートポンプの使用では、効果的に熱利用を行ってヒートポンプを効率良く安定した運転とすることが困難であった。   When using artificial exhaust heat such as domestic waste heat or factory exhaust heat, the exhaust heat temperature often changes with time, and the use of conventional heat pumps effectively uses heat to It was difficult to achieve efficient and stable operation.
本発明は、上述の様なヒートポンプ装置と自然エネルギー又は人工排熱とのマッチングの問題を解決し、採熱エネルギー量が安定しない自然エネルギーや人工排熱エネルギーを利用し、逆カルノーサイクル原理を利用したヒートポンプシステムとして効率良く熱エネルギーを採取利用することのできる冷温熱発生装置を提供するものである。   The present invention solves the problem of matching between the heat pump device as described above and natural energy or artificial exhaust heat, uses natural energy or artificial exhaust heat energy whose heat collection energy amount is not stable, and uses the reverse Carnot cycle principle The present invention provides a cold / hot heat generator that can efficiently collect and use thermal energy as a heat pump system.

更に、前記温度調整槽は、下部で連接されるように分離された二つの貯留室を有し、一方の貯留室から熱媒を排出し、他方の貯留室に熱媒を流入させるように各採熱器を介して熱媒を循環させ、前記複数の採熱器に熱媒を循環させるように送ることにより、当該温度調整槽と各採熱器との熱交換を行う冷温熱発生装置とするものである。   Further, the temperature control tank has two storage chambers separated so as to be connected to each other at the lower part, and discharges the heat medium from one storage chamber and allows the heat medium to flow into the other storage chamber.

また、前記採熱器は、自然熱を採取する熱交換パイプ及び人工排熱を採取する熱交換パイプであって、複数の異なる前記各熱源に前記熱交換パイプが各々配置され、前記温度調整槽の熱媒が当該各熱交換パイプである採熱器を通して循環する冷温熱発生装置とするものである。   Further, the heat collector is a heat exchange pipe for collecting natural heat and a heat exchange pipe for collecting artificial waste heat, wherein the heat exchange pipes are respectively disposed in a plurality of different heat sources, and the temperature adjustment tank This heat medium is a cold / hot heat generator that circulates through a heat collector that is each heat exchange pipe.
そして、前記自然熱を採取する熱交換パイプは、地中に配された熱交換パイプ、太陽熱集熱パネルの熱交換パイプ、河川や湖沼の水中に配された熱交換パイプ、空気との接触を行うように配された熱交換パイプ、雪捨て場に配された熱交換パイプ、の何れかであり、前記人工排熱を採取する熱交換パイプは、下水管や下水槽又は排水溝や排水槽に配置されて生活排水熱を吸収する熱交換パイプ、下水管や下水槽又は排水溝や排水槽に配置されて工場排水熱を吸収する熱交換パイプ、堆肥場に配された熱交換パイプ、発酵槽に配された熱交換パイプ、の何れかである冷温熱発生装置とするものである。   The heat exchange pipe that collects natural heat includes a heat exchange pipe arranged in the ground, a heat exchange pipe for a solar heat collecting panel, a heat exchange pipe arranged in the water of a river or a lake, and contact with air.

そして、前記温度調整槽に貯える熱媒温度を10℃乃至30℃の範囲内とする冷温熱発生装置とするものである。   And it is set as the cold / heat generating device which makes the heat-medium temperature stored in the said temperature control tank in the range of 10 to 30 degreeC.
更に、前記各採熱器には温度計を備え、前記各採熱器と前記温度調整槽とを接続する熱媒回路には、電磁弁又は循環ポンプを備える冷温熱発生装置とするものである。   Further, each of the heat collectors is provided with a thermometer, and the heat medium circuit connecting the heat collectors and the temperature control tank is a cold / hot heat generator provided with an electromagnetic valve or a circulation pump. .
本発明に係る冷温熱発生装置は、複数の熱源から採熱を行う複数の採熱器を温度調整槽と接続しているため、各熱源の温度が時間的、季節的に変動しても、温度調整槽に蓄える熱媒の温度を所定範囲内に安定させることができる。   The cold / hot heat generator according to the present invention connects a plurality of heat collectors that collect heat from a plurality of heat sources to a temperature adjustment tank, so even if the temperature of each heat source varies temporally and seasonally, The temperature of the heat medium stored in the temperature adjustment tank can be stabilized within a predetermined range.
このため、温度調整槽に貯えた熱媒の温度による熱エネルギーを利用して、圧縮機及び膨張弁による温度上昇や温度降下を効率良く安定させて行うことができ、効率的な熱利用を可能として、冷温熱発生熱交換器から熱負荷に対して冷熱又は温熱を供給することができる。また、複数の熱源から採熱を行うため、各熱源への負担を軽減することもできる。   For this reason, the heat energy generated by the temperature of the heat medium stored in the temperature adjustment tank can be used to efficiently and stably stabilize the temperature rise and temperature drop caused by the compressor and expansion valve, enabling efficient heat utilization. As described above, cold heat or heat can be supplied from the cold heat generating heat exchanger to the heat load. Moreover, since heat is collected from a plurality of heat sources, the burden on each heat source can be reduced.
更に、温度調整槽と冷温熱発生熱交換器とを接続する配管に膨張弁と四方弁を介した圧縮機とを設けることにより、冷温熱発生装置の構造を単純として冷温熱発生装置の設置を容易に行うことができる。   Furthermore, by installing an expansion valve and a compressor via a four-way valve in the pipe connecting the temperature adjustment tank and the cold / heat generating heat exchanger, the structure of the cold / hot heat generator can be simplified and the cold / hot heat generator can be installed. It can be done easily.
そして、温度調整槽内に熱交換パイプを備えることにより、圧縮機から冷温熱発生熱交換器及び膨張弁を循環させる熱媒と、採熱器により熱源と熱交換を行って温度調整槽に蓄えられる熱媒と、を異なる熱媒とすることを可能とすることができる。このため、圧縮・凝縮により液化され、膨張・蒸発により気化するように液化及び気化するために取扱に注意を要する熱媒を、離れた複数の熱源に配置した採熱器に送る必要が無く、熱源の採熱器に送る熱媒を取扱い容易な熱媒として、熱源からの採熱を容易に行うことができる。   And, by providing a heat exchange pipe in the temperature adjustment tank, heat exchange with the heat source that circulates the cold heat generation heat exchanger and the expansion valve from the compressor and the heat source by the heat collector and stores in the temperature adjustment tank It is possible to make the heating medium to be a different heating medium. For this reason, it is not necessary to send a heat medium that needs to be handled carefully to be liquefied and vaporized so as to be liquefied by compression / condensation and vaporized by expansion / evaporation, to heat collectors arranged in a plurality of distant heat sources, The heat medium sent to the heat source heat collector can be easily handled as a heat medium that can be easily handled.
また、温度調整槽と冷温熱発生熱交換器との間に補助熱交換器と循環ポンプとを配置することにより、圧縮機や膨張弁、冷温熱発生熱交換器を循環させる熱媒と、温度調整槽に蓄えて補助熱交換器を循環させる熱媒とを異なる熱媒とすることを可能とし、且つ、補助熱交換器や冷温熱発生熱交換器、圧縮機、四方弁、膨張弁を近接した位置に配置することを可能として、冷温熱発生装置の設置を容易とし、且つ、熱源の採熱器に送る熱媒を取扱い容易な熱媒とすることにより、熱源からの採熱を容易に行うことができる。   Further, by arranging an auxiliary heat exchanger and a circulation pump between the temperature adjustment tank and the cold / heat generating heat exchanger, a heat medium that circulates the compressor, the expansion valve, and the cold / heat generating heat exchanger, and the temperature The heat medium stored in the adjustment tank and circulating through the auxiliary heat exchanger can be a different heat medium, and the auxiliary heat exchanger, the cold / heat generating heat exchanger, the compressor, the four-way valve, and the expansion valve are close to each other. This makes it easy to install a cold / hot heat generator, and makes it easy to handle the heat medium sent to the heat source heat collector, making it easy to collect heat from the heat source. It can be carried out.
更に、温度調整槽に二つの貯留室を設けて両貯留室を下部で連接し、一方の貯留室に熱媒を流入させて他方の貯留室から熱媒を排出させるように各採熱器に熱媒を送って循環させることにより、一方の貯留室と他方の貯留室とで温度差を生じさせて冷温熱発生熱交換器側へ流出する熱媒や冷温熱発生熱交換器側から流入する熱媒と温度調整槽に蓄えられた熱媒との熱交換を効率良く行うことができる。   Furthermore, two storage chambers are provided in the temperature adjustment tank, both the storage chambers are connected at the lower part, and each heat collector is connected so that the heat medium flows into one storage chamber and the heat medium is discharged from the other storage chamber. By sending and circulating the heat medium, a temperature difference is generated between one storage chamber and the other storage chamber, and the heat medium flows out to the cold / heat generation heat exchanger side or flows from the cold / heat generation heat exchanger side. Heat exchange between the heat medium and the heat medium stored in the temperature adjustment tank can be performed efficiently.
そして、自然熱や人工排熱を採熱器で集熱することにより、容易に逆カルノーサイクル原理を利用するヒートポンプ方式を採用することができ、複数の異なる熱源から採熱することにより安定した温度の熱源熱として効率良く熱利用を図ることができる。   And by collecting natural heat or artificial waste heat with a heat collector, a heat pump system that uses the inverse Carnot cycle principle can be easily adopted, and stable temperature is obtained by collecting heat from multiple different heat sources. The heat can be efficiently used as the heat source heat.
また、地中熱や太陽熱、空気熱等の自然熱を集熱する熱交換パイプ、生活排水熱や工場排水熱等の人工排熱を集熱する熱交換パイプを採熱器として自然熱や人工排熱を集熱すれば、熱の収集を容易に行うことができる。   In addition, natural heat and artificial heat are collected from heat exchange pipes that collect natural heat such as underground heat, solar heat, and air heat, and heat exchange pipes that collect artificial waste heat such as domestic wastewater heat and factory wastewater heat. If exhaust heat is collected, heat can be collected easily.
更に、温度調整槽の温度を10℃乃至30℃の範囲内とする事によって、逆カルノーサイクル原理を利用するに際し、余り価値を見出せない拡散した低温熱や、人工排熱などの高温であるが熱交換器のみでは利用価値を生まないままの少量の高温熱でも、他の低温熱と混合して利用することで有効な熱として、既存の一般的なヒートポンプの熱利用と比べて高効率の熱利用を行うことができる。   Furthermore, by setting the temperature of the temperature adjustment tank within the range of 10 ° C. to 30 ° C., when using the inverse Carnot cycle principle, it is a high temperature such as diffused low-temperature heat and artificial exhaust heat that cannot find much value. Even with a small amount of high-temperature heat that does not produce useful value with only a heat exchanger, it can be used as an effective heat by mixing it with other low-temperature heat. Heat can be used.
また、採熱器に温度計を設けることにより各熱源の温度状態を検出することを可能とし、電磁弁又は循環ポンプを設けることにより、適切な熱源を選択して熱を温度調整槽に移動させることができる。そして、循環ポンプを設けることにより熱媒の強制循環を可能とすれば、温度調整槽の温度調整を迅速且つ確実に行うことができる。   In addition, it is possible to detect the temperature state of each heat source by providing a thermometer in the heat collector, and by selecting an appropriate heat source to move the heat to the temperature adjustment tank by providing a solenoid valve or a circulation pump. be able to. And if forced circulation of a heat medium is enabled by providing a circulation pump, the temperature adjustment of a temperature adjustment tank can be performed quickly and reliably.

The heat medium that has passed through 119 can be sucked into the compressor 211.
そして、この四方弁213の切換操作を行って第1開口213a及び第3開口213cを第1配管201に接続するようにして、第2開口213bを圧縮機211の熱媒吐出口と接続し、第4開口213dを圧縮機211の熱媒吸入口と接続した状態に切換えると、圧縮機211から吐出された熱媒を温度調整槽110内の熱交換パイプ119に送り、第2配管202により膨張弁215及び冷温熱発生熱交換器190に送って冷温熱発生熱交換器190の一次側コイルを介した熱媒を圧縮機211に吸い込むことができるものである。   Then, by switching the four-way valve 213, the first opening 213a and the third opening 213c are connected to the first pipe 201, and the second opening 213b is connected to the heat medium outlet of the compressor 211, When the fourth opening 213d is switched to the state connected to the heat medium inlet of the compressor 211, the heat medium discharged from the compressor 211 is sent to the heat exchange pipe 119 in the temperature adjustment tank 110 and expanded by the second pipe 202. The heat medium that is sent to the valve 215 and the cold / heat generating heat exchanger 190 and that passes through the primary coil of the cold / heat generating heat exchanger 190 can be sucked into the compressor 211.
また、冷温熱発生熱交換器190は、二次側コイルと負荷用往路191及び負荷用復路192とを接続し、負荷用往路191及び負荷用復路192は図示しない熱負荷と接続するものである。   The cold / hot heat generating heat exchanger 190 connects the secondary coil to the load outbound path 191 and the load return path 192, and the load outbound path 191 and the load return path 192 are connected to a thermal load (not shown). .
この熱負荷としては、空調機や温水器、冷水器などが冷温熱発生熱交換器190に接続されるものであり、空調機に冷温熱発生熱交換器190から冷熱を送り、屋内冷房に利用し、また、空調機に冷温熱発生熱交換器190から温熱を送り、屋内暖房を行うことができる。   As this heat load, air conditioners, water heaters, water chillers, etc. are connected to the cold heat generating heat exchanger 190, and the cold air is sent from the cold heat generating heat exchanger 190 to the indoor air conditioner. In addition, it is possible to perform indoor heating by sending heat from the cold / hot heat generating heat exchanger 190 to the air conditioner.
そして、冷水器では、冷温熱発生熱交換器190からの冷熱により上水(水道水)を10℃程度に冷却して冷水とし、また、冷温熱発生熱交換器190の温熱により上水(水道水)を50℃程度の温水とすることにより、生活用水として冷水や温水の利用を可能とするものである。   In the chiller, the cold water (tap water) is cooled to about 10 ° C. by cold heat from the cold / hot heat generating heat exchanger 190, and the cold water is supplied to the hot water (tap water) by the heat of the cold / heat generating heat exchanger 190. By making the water) hot water of about 50 ° C., it is possible to use cold water or hot water as domestic water.
また、冷水や温水は、生活用水として利用する場合に限ることなく、壁や床に設けた配管を循環させ、壁冷房や壁暖房、又は床冷房や床暖房を行うようにすることもある。   In addition, cold water and hot water are not limited to use as water for daily life, and pipes provided on walls and floors may be circulated to perform wall cooling or wall heating, or floor cooling or floor heating.
即ち、図1に示した第2開口213b及び第4開口213dを第1配管201に接続して圧縮機211を四方弁213により第1配管201に接続した状態では、温度調整槽110内の熱交換パイプ119を通した熱媒を圧縮機211に吸い込み、圧縮機211で熱媒を圧縮することにより熱媒を昇温させ、50℃乃至60℃程度の温度の高圧熱媒として冷温熱発生熱交換器190の一次側コイル225に送ることができる。   That is, when the second opening 213b and the fourth opening 213d shown in FIG. 1 are connected to the first pipe 201 and the compressor 211 is connected to the first pipe 201 by the four-way valve 213, the heat in the temperature adjusting tank 110 is The heat medium passed through the exchange pipe 119 is sucked into the compressor 211, and the heat medium is compressed by the compressor 211 to raise the temperature of the heat medium. It can be sent to the primary coil 225 of the exchanger 190.
そして、冷温熱発生熱交換器190の一次側コイル225を通過した熱媒を膨張弁215を通して気化させることにより7℃乃至15℃程度の温度に降下させ、低温とされた熱媒を温度調整槽110内の熱交換パイプ119に送ることができ、冷温熱発生熱交換器190から温熱を取出して熱負荷に供給し、温熱を生活に利用することができる。   Then, the heat medium that has passed through the primary coil 225 of the cold / heat generating heat exchanger 190 is vaporized through the expansion valve 215 to be lowered to a temperature of about 7 ° C. to 15 ° C. The heat can be sent to the heat exchange pipe 119 in 110, and the heat can be taken out from the cold heat generating heat exchanger 190 and supplied to the heat load, and the heat can be used for daily life.
このように、圧縮機211により圧縮昇温させた熱媒を冷温熱発生熱交換器190に送り、冷温熱発生熱交換器190から50℃乃至60℃程度の温熱を負荷側に取り出し、膨張弁215を介して温度調整槽110内の熱交換パイプ119に7℃乃至15℃程度の熱媒が注入されるときは、熱源の温度が20℃以上である熱源に設けた採熱器から温度調整槽110に熱エネルギーを送る様に、第1循環ポンプ131乃至第5循環ポンプ135の内の所要温度に該当する熱源の採熱器に接続される循環ポンプを駆動して熱源からの熱を温度調整槽110に移動させ、温度調整槽110に貯えられる熱媒の温度を10℃乃至30℃の間で圧縮機211や膨張弁215の特性に合わせた所定の一定温度とするものである。   In this way, the heat medium compressed and heated by the compressor 211 is sent to the cold / heat generating heat exchanger 190, and the heat of about 50 ° C. to 60 ° C. is taken out from the cold / heat generating heat exchanger 190 to the load side. When a heat medium of about 7 ° C. to 15 ° C. is injected into the heat exchange pipe 119 in the temperature adjustment tank 110 via 215, the temperature adjustment is performed from the heat collector provided in the heat source where the temperature of the heat source is 20 ° C. or higher. The temperature of the heat from the heat source is increased by driving the circulation pump connected to the heat collector of the heat source corresponding to the required temperature in the first circulation pump 131 to the fifth circulation pump 135 so as to send the heat energy to the tank 110. The temperature of the heat medium stored in the temperature adjusting tank 110 is set to a predetermined constant temperature between 10 ° C. and 30 ° C. according to the characteristics of the compressor 211 and the expansion valve 215.
また、四方弁213を切り換えて四方弁213の第1開口213a及び第3開口213cを第1配管201に接続して圧縮機211を四方弁213により第1配管201に接続すれば、第1配管201内の熱媒は、圧縮機211により50℃乃至60℃程度の温度とされる高圧熱媒となって温度調整槽110に送られ、温度調整槽110内の熱交換パイプ119により温度調整槽110内で放熱する。   If the four-way valve 213 is switched to connect the first opening 213a and the third opening 213c of the four-way valve 213 to the first pipe 201 and the compressor 211 is connected to the first pipe 201 by the four-way valve 213, the first pipe is provided. The heat medium in 201 becomes a high-pressure heat medium having a temperature of about 50 ° C. to 60 ° C. by the compressor 211 and is sent to the temperature adjustment tank 110, and the temperature adjustment tank 119 by the heat exchange pipe 119 in the temperature adjustment tank 110. Heat is dissipated in 110.
そして、温度調整槽110と連通されている第1採熱器121から第5採熱器125の各採熱器の温度状況により、50℃以下の所定の熱源に放熱して熱交換パイプ119内の温度降下をさせるように作用させ、熱交換パイプ119を通った熱媒は温度降下しながら膨張弁215に送られ、膨張弁215で一気に開放されることにより7℃乃至15℃程度の温度に降下させて冷温熱発生熱交換器190の一次側コイル225に送ることができ、冷温熱発生熱交換器190から冷熱を取出して熱負荷に供給し、冷熱を生活に利用することができる。   Then, depending on the temperature condition of each heat collector from the first heat collector 121 to the fifth heat collector 125 communicated with the temperature adjustment tank 110, the heat is radiated to a predetermined heat source of 50 ° C. or less, and inside the heat exchange pipe 119. The heat medium that has passed through the heat exchange pipe 119 is sent to the expansion valve 215 while the temperature drops, and is released at once by the expansion valve 215 to reach a temperature of about 7 ° C. to 15 ° C. The temperature can be lowered and sent to the primary coil 225 of the cold / heat generating heat exchanger 190. The cold heat can be taken out from the cold / heat generating heat exchanger 190 and supplied to the heat load, and the cold can be used in daily life.
そして、冷温熱発生熱交換器190から7℃乃至15℃程度の冷熱が負荷側に取り出され、温度調整槽110内の熱交換パイプ119に50℃乃至60℃程度の熱媒が注入され、温度調整槽110内に50℃乃至60℃程度の熱媒が発生して対流しているときは、熱源の温度が30℃乃至50℃以下である熱源に設けた採熱器から温度調整槽110に熱エネルギーを送る様に第1循環ポンプ131乃至第5循環ポンプ135の内の該当する熱源の採熱器に接続される循環ポンプを駆動して熱源からの熱を温度調整槽110に移動させ、温度調整槽110に貯えられる熱媒の温度を10℃乃至30℃の間で圧縮機211や膨張弁215の特性に合わせた所定の一定温度とするものである。   Then, cold heat of about 7 ° C. to 15 ° C. is taken out from the cold heat generation heat exchanger 190 to the load side, and a heat medium of about 50 ° C. to 60 ° C. is injected into the heat exchange pipe 119 in the temperature adjustment tank 110, When a heating medium of about 50 ° C. to 60 ° C. is generated and convected in the adjustment tank 110, the temperature of the heat source is from 30 ° C. to 50 ° C. to the temperature adjustment tank 110 from the heat collector provided in the heat source. Drive the circulation pump connected to the heat collector of the corresponding heat source in the first circulation pump 131 to the fifth circulation pump 135 so as to send the heat energy, and move the heat from the heat source to the temperature adjustment tank 110, The temperature of the heat medium stored in the temperature adjusting tank 110 is set to a predetermined constant temperature between 10 ° C. and 30 ° C. according to the characteristics of the compressor 211 and the expansion valve 215.
また、この冷温熱発生装置100は、制御盤240を有し、スイッチ操作に基づいて四方弁213の接続切換を制御盤240により制御し、冷温熱発生熱交換器190から10℃程度の冷熱を熱負荷に供給し、また、50℃程度の温熱を熱負荷に供給することができるようにしているものである。   The cold / heat generating apparatus 100 also has a control panel 240, and controls the switching of the connection of the four-way valve 213 by the control panel 240 based on the switch operation, so that the cool / heat generating heat exchanger 190 can cool about 10 ° C. The heat load is supplied, and the heat of about 50 ° C. can be supplied to the heat load.
そして、この制御盤240は、調整槽温度計169により温度調整槽110内の熱媒温度を検出すると共に、第1温度計161乃至第5温度計165により第1採熱器121乃至第5採熱器125における熱媒温度も検出し、温度調整槽110の温度を10℃乃至30℃の範囲内であって所定の目標温度とするように、第1採熱器121乃至第5採熱器125の内、採熱に適した熱源に設置した採熱器に熱媒を送る様に、第1循環ポンプ131、第2循環ポンプ132、第3循環ポンプ133、第4循環ポンプ134、第5循環ポンプ135の駆動及び停止の制御を行うものである。   The control panel 240 detects the temperature of the heat medium in the temperature adjustment tank 110 by using the adjustment tank thermometer 169, and uses the first thermometer 161 to the fifth thermometer 165 to detect the first heat collector 121 to the fifth sampling. The temperature of the heat medium in the heater 125 is also detected, and the first heat collector 121 to the fifth heat collector are set so that the temperature of the temperature adjustment tank 110 is within a range of 10 ° C. to 30 ° C. and a predetermined target temperature. The first circulating pump 131, the second circulating pump 132, the third circulating pump 133, the fourth circulating pump 134, the fifth circulating pump 131, the second circulating pump 132, the fourth circulating pump 134, the fifth circulating pump 131, and the like. Control of driving and stopping of the circulation pump 135 is performed.
また、採熱器としては、前述の5種類の熱源に配置するものの他、温泉排水などの水路に熱交換パイプを配置して温水熱を採取する場合、雪捨て場の地表近傍等に熱交換パイプを埋設配置して氷雪熱を採取する場合、堆肥場の地表近傍等に熱交換パイプを配置して堆肥等の発酵熱を採取する場合、発酵槽内に熱交換パイプを配置して発酵熱を採取する場合、工場排熱やボイラー排熱を採取する熱交換パイプ等、種々の採熱対象とする熱源から熱を採取可能とする熱交換パイプを用いることが有る。   In addition to the heat collectors that are placed in the five types of heat sources described above, heat exchange pipes are placed in waterways such as hot spring drainage to collect hot water heat. When collecting ice and snow heat by laying pipes, when exchanging heat exchange pipes near the surface of the compost site and collecting fermentation heat such as compost, heat exchange pipes are placed in the fermenter When collecting heat, a heat exchange pipe that can collect heat from various heat sources, such as a heat exchange pipe that collects factory exhaust heat or boiler exhaust heat, may be used.
そして、調整槽温度計169と接続する採熱器の数も5個に限ることなく、3個以上の適宜の数の熱源を使用すれば足り、地中熱、空気熱、太陽光熱、生活排水熱等の家屋の周囲で採熱を容易に行える熱源を使用すれば、冷温熱発生装置100の設置が容易となる。また、設置場所や状況により、近隣の適宜の熱源を追加すれば、より一層安定した効率の良い熱利用を行うことができる。   Further, the number of heat collectors connected to the adjustment tank thermometer 169 is not limited to five, and it is sufficient to use an appropriate number of heat sources of three or more, underground heat, air heat, solar heat, domestic wastewater. If a heat source that can easily collect heat around a house such as heat is used, the cold / hot heat generator 100 can be easily installed. Moreover, if an appropriate heat source nearby is added depending on the installation location and situation, it is possible to use heat more stably and efficiently.
このように、この冷温熱発生装置100は、圧縮機211及び膨張弁215により温度調整槽110と冷温熱発生熱交換器190との間に温度差を生じさせ、温度調整槽110に熱源からの熱を集熱して所定範囲の温度とする熱媒を蓄えておくものであるから、圧縮機211から吐出する熱媒を温度調整槽110側に送り出すか、冷温熱発生熱交換器190側に送り出すかを、四方弁213により切り換えるのみで冷温熱発生熱交換器190から冷熱又は温熱を取り出すことができ、複数の熱源の温度状態を検出し、温度調整槽110の温度を所定の目標温度とすることにより、圧縮機211及び膨張弁215の機能を高効率として逆カルノーサイクル原理を用いた冷温熱発生装置100を作動させることができる。   As described above, the cold / heat generating apparatus 100 causes the compressor 211 and the expansion valve 215 to generate a temperature difference between the temperature adjusting tank 110 and the cool / heat generating heat exchanger 190, and causes the temperature adjusting tank 110 to receive heat from the heat source. Since the heat medium that collects heat and keeps the temperature within a predetermined range is stored, the heat medium discharged from the compressor 211 is sent out to the temperature adjustment tank 110 side or sent out to the cold / heat generating heat exchanger 190 side The heat or heat can be taken out from the heat / heat generation heat exchanger 190 simply by switching the four-way valve 213, the temperature state of the plurality of heat sources is detected, and the temperature of the temperature adjustment tank 110 is set to a predetermined target temperature. As a result, it is possible to operate the cold / hot heat generator 100 using the inverse Carnot cycle principle with the functions of the compressor 211 and the expansion valve 215 being highly efficient.
更に、熱源として複数の熱源を利用するため、各熱源への負担を軽減し、空気熱を利用する場合にも大気中からの吸熱を減少させ、また、大気中への放熱を減少させてヒートアイランド現象を軽減させることができ、地中熱を利用する場合においては、採熱器とする熱交換パイプの設置に際し、地中深くの広範囲に設置する必要をなくし、地中に埋設する第1採熱器121の設置、ひいては冷温熱発生装置100の設置を容易とすることができる。   In addition, since multiple heat sources are used as heat sources, the burden on each heat source is reduced, heat absorption from the atmosphere is reduced even when air heat is used, and heat radiation to the atmosphere is reduced to reduce heat islands. The phenomenon can be reduced, and when using underground heat, it is not necessary to install a heat exchanging pipe as a heat collecting device in the deep underground, and the first sampling buried in the ground. The installation of the heater 121 and, in turn, the installation of the cold / hot heat generator 100 can be facilitated.
そして、余り利用価値を見出せない拡散した低温熱の熱源や、人工排熱などの高温であるが熱交換器のみでは利用価値を生まないままの少量の高温熱の熱源であっても、他の低温熱熱源や少量高温熱源の熱と混合させるように利用することにより、各々の熱源に大きな負荷をかけることなく有効な熱源として熱利用を行うことができるものである。   And even if it is a heat source of diffused low-temperature heat that cannot find much use value or a high-temperature heat source such as artificial exhaust heat, but only a small amount of high-temperature heat source that does not produce useful value with only a heat exchanger, By using it so as to be mixed with heat from a low-temperature heat source or a small amount of high-temperature heat source, heat can be used as an effective heat source without imposing a large load on each heat source.
また、本発明の第2の実施の形態は、図2に示すように、貯留槽171を設けると共に、温度調整槽110に貯留用熱交換器128を接続して温度調整槽110と貯留槽171の間の熱移動を可能とするものである。   Further, in the second embodiment of the present invention, as shown in FIG. 2, a storage tank 171 is provided, and a storage heat exchanger 128 is connected to the temperature adjustment tank 110 to connect the temperature adjustment tank 110 and the storage tank 171.

この貯留用熱交換器128は、一次側コイルを温度調整槽110に接続するように第6循環ポンプ138を有する貯留用往路148により一次側コイルの一端と温度調整槽110を接続し、貯留用熱交換器128を介した熱媒を温度調整槽110に戻すように一次側コイルの他端と温度調整槽110とを貯留用復路158により接続するものである。   This storage heat exchanger 128 connects one end of the primary side coil and the temperature adjustment tank 110 by a storage forward path 148 having a sixth circulation pump 138 so as to connect the primary side coil to the temperature adjustment tank 110, The other end of the primary coil and the temperature adjustment tank 110 are connected by a storage return path 158 so that the heat medium via the heat exchanger 128 is returned to the temperature adjustment tank 110.
また、貯留用熱交換器128の二次側コイルは、貯留循環ポンプ173を備える貯留循環路175により貯留槽171と接続して貯留槽171に蓄えた水を貯留用熱交換器128に循環させるものとし、貯留槽171に蓄えた水の水温を検出する貯留槽温度計168を設けるものである。   The secondary coil of the storage heat exchanger 128 is connected to the storage tank 171 by a storage circuit 175 having a storage circulation pump 173 and circulates the water stored in the storage tank 171 to the storage heat exchanger 128. A storage tank thermometer 168 for detecting the water temperature of the water stored in the storage tank 171 is provided.
そして、この貯留槽温度計168で検出する水温情報も制御盤240に入力し、貯留槽171に蓄えた水の温度を温度調整槽110の所定温度に合わせるように貯留循環ポンプ173及び第6循環ポンプ138を駆動制御することにより、冷温熱発生熱交換器190から冷熱や温熱を取り出し、温度調整槽110に蓄えた熱媒温度が所定温度から外れるとき、適正温度の熱源が無い場合でも、貯留槽171に蓄えた熱エネルギーにより温度調整槽110の温度変化を小さくすることができるものである。   Water temperature information detected by the storage tank thermometer 168 is also input to the control panel 240, and the storage circulation pump 173 and the sixth circulation are adjusted so that the temperature of the water stored in the storage tank 171 matches the predetermined temperature of the temperature adjustment tank 110. By controlling the driving of the pump 138, the cold heat and heat are taken out from the cold heat generation heat exchanger 190, and when the temperature of the heat medium stored in the temperature adjustment tank 110 deviates from the predetermined temperature, even if there is no heat source at an appropriate temperature, storage is performed. The temperature change of the temperature adjustment tank 110 can be reduced by the heat energy stored in the tank 171.
尚、貯留用熱交換器128を省略し、温度調整槽110内の熱媒を貯留槽171に抜き出して貯めておき、圧縮機211を駆動させることにより温度調整槽110内の熱媒温度が上昇または降下するとき、貯留槽171に貯めた熱媒を温度調整槽110に移動させて温度調整槽110内の熱媒温度の上昇または降下を小さくさせることもできる。   The storage heat exchanger 128 is omitted, the heat medium in the temperature adjustment tank 110 is extracted and stored in the storage tank 171, and the compressor 211 is driven to increase the temperature of the heat medium in the temperature adjustment tank 110.

また、上述の冷温熱発生装置100は、温度調整槽110の熱媒を第1循環ポンプ131、第2循環ポンプ132、第3循環ポンプ133、第4循環ポンプ134、第5循環ポンプ135とした循環ポンプにより熱媒を各採熱器に送るようにしているも、循環ポンプを使用しないこともある。   In the cold / heat generating apparatus 100 described above, the heat medium in the temperature adjusting tank 110 is the first circulation pump 131, the second circulation pump 132, the third circulation pump 133, the fourth circulation pump 134, and the fifth circulation pump 135. Although the heat medium is sent to each heat collector by the circulation pump, the circulation pump may not be used.
この第3の実施の形態は、図3に示すように、第1循環ポンプ131乃至第5循環ポンプ135に換えて第1電磁弁181、第2電磁弁182、第3電磁弁183、第4電磁弁184、第5電磁弁185を各々第1熱源往路141、第2熱源往路142、第3熱源往路143、第4熱源往路144、第5熱源往路145に設けているものであって、熱源に配置する採熱器と温度調整槽110との接続において、採熱器と温度調整槽110との位置関係や配管の設置状況により熱媒をポンプにより強制循環させる必要がない状態の場合に実施するものである。   In the third embodiment, as shown in FIG. 3, instead of the first circulation pump 131 to the fifth circulation pump 135, a first electromagnetic valve 181, a second electromagnetic valve 182, a third electromagnetic valve 183, An electromagnetic valve 184 and a fifth electromagnetic valve 185 are provided in the first heat source forward path 141, the second heat source forward path 142, the third heat source forward path 143, the fourth heat source forward path 144, and the fifth heat source forward path 145, respectively. Executed when there is no need to forcibly circulate the heat medium with a pump depending on the positional relationship between the heat collector and the temperature adjustment tank 110 and the installation status of the pipes in the connection between the heat collector and the temperature adjustment tank 110 To do.
即ち、熱源に配置された採熱器内の熱媒温度と温度調整槽110に蓄えられている熱媒の温度との温度差により、第1熱源往路141、第2熱源往路142、第3熱源往路143、第4熱源往路144、第5熱源往路145の各熱源往路から第1採熱器121、第2採熱器122、第3採熱器123、第4採熱器124、第5採熱器125を介して第1熱源復路151、第2熱源復路152、第3熱源復路153、第4熱源復路154、第5熱源復路155により温度調整槽110に熱媒が戻るように、各熱源往路、採熱器、及び熱源復路において熱媒が自然循環して温度調整槽110に熱移動が行われるとき、循環ポンプを廃止して冷温熱発生装置100におけるエネルギー消費を少なくすることができるものである。   That is, the first heat source forward path 141, the second heat source forward path 142, and the third heat source are determined by the temperature difference between the temperature of the heat medium in the heat collector disposed in the heat source and the temperature of the heat medium stored in the temperature adjustment tank 110. The first heat collector 121, the second heat collector 122, the third heat collector 123, the fourth heat collector 124, and the fifth sample are taken from each of the heat source forward paths 143, the fourth heat source forward path 144, and the fifth heat source forward path 145.

When the heat medium naturally circulates in the forward path, the heat collector, and the heat source return path and heat transfer is performed to the temperature adjustment tank 110, the circulation pump can be eliminated to reduce the energy consumption in the cold / hot heat generator 100. It is.
そして、熱源温度が温度調整槽110内の温度よりも高く、温度調整槽110の温度を低下させることが必要な状態のときは、所定温度よりも高い熱源への循環往路に設けた電磁弁を閉じ、同様に熱源温度が低く温度調整槽110内の熱媒温度を上昇させることが必要なときは、一定の温度よりも低い熱源への循環往路に設けた電磁弁を閉じるようにして、温度調整槽110の目標温度達成に適さない熱源との熱移動を阻止するものである。   And when the temperature of the heat source is higher than the temperature in the temperature adjustment tank 110 and it is necessary to lower the temperature of the temperature adjustment tank 110, an electromagnetic valve provided in the circulation outward path to the heat source higher than the predetermined temperature is provided. Similarly, when the heat source temperature is low and the temperature of the heat medium in the temperature adjusting tank 110 needs to be raised, close the solenoid valve provided in the circulation path to the heat source lower than a certain temperature, The heat transfer with the heat source that is not suitable for achieving the target temperature of the adjustment tank 110 is prevented.
また、図3に示した第3の実施の形態は、第1採熱器121乃至第5採熱器125への全ての熱源往路に電磁弁を設けているも、採熱器の設置場所及び配管の状態により自然循環が行われる熱源への配管には電磁弁を設け、自然循環では熱移動の効率が悪い熱源への配管には循環用ポンプとしての循環ポンプを設けることとし、自然循環により熱を採取する熱源と強制循環により熱を採取する熱源とを組み合わせることもある。   Further, in the third embodiment shown in FIG. 3, electromagnetic valves are provided in all the heat source outgoing paths to the first heat collector 121 to the fifth heat collector 125, A solenoid valve is provided for the pipe to the heat source where natural circulation is performed according to the state of the pipe, and a circulation pump as a circulation pump is provided for the pipe to the heat source where the heat transfer efficiency is poor in natural circulation. A heat source for collecting heat may be combined with a heat source for collecting heat by forced circulation.

Is connected to the second pipe 202.
そして、補助熱交換器221の二次側コイル227の一端と冷温熱発生熱交換器190の一次側コイルの一端とを接続する第1補助配管231に四方弁213を配置して圧縮機211を四方弁213と接続し、補助熱交換器221の二次側コイル227の他端と冷温熱発生熱交換器190の一次側コイルの他端とを接続する第2補助配管232に膨張弁215を配置するものである。   Then, a four-way valve 213 is arranged in the first auxiliary pipe 231 connecting one end of the secondary side coil 227 of the auxiliary heat exchanger 221 and one end of the primary side coil of the cold / hot heat generating heat exchanger 190 to arrange the compressor 211. An expansion valve 215 is connected to the second auxiliary pipe 232 connected to the four-way valve 213 and connecting the other end of the secondary coil 227 of the auxiliary heat exchanger 221 and the other end of the primary coil of the cold / heat generating heat exchanger 190.

従って、冷温熱発生熱交換器190と温度調整槽110とを補助熱交換器221を介して熱的に接続しつつ、第1配管201及び第2配管202を流れる熱媒と第1補助配管231及び第2補助配管232を流れる熱媒とを異なる熱媒とすることができ、温度調整槽110に蓄える熱媒を水などの取り扱いが容易な熱媒とすることができることは、前述の実施の形態と同様である。   Accordingly, the heat medium flowing through the first pipe 201 and the second pipe 202 and the first auxiliary pipe 231 while the cold heat generating heat exchanger 190 and the temperature adjustment tank 110 are thermally connected via the auxiliary heat exchanger 221. The heating medium flowing through the second auxiliary pipe 232 can be a different heating medium, and the heating medium stored in the temperature control tank 110 can be a heating medium that is easy to handle such as water. It is the same as the form.
そして、この場合も、図1等に示した形態と同様に、四方弁213の切換により、冷温熱発生熱交換器190から7℃程度の冷熱を熱負荷に供給し、また、50℃程度の温熱を熱負荷に供給することができる。そして、熱源として複数の熱源を利用し、温度調整槽110の温度を所定の温度とすることにより、各熱源への負担を軽減することができると共に、圧縮機211及び膨張弁215も効率良く利用することができる。   In this case as well, as in the embodiment shown in FIG. 1 and the like, by switching the four-way valve 213, cold heat of about 7 ° C. is supplied to the heat load from the cold / heat generating heat exchanger 190, and about 50 ° C. Warm heat can be supplied to the heat load.
