Description

本発明は、地熱を利用した冷暖房システム及びその制御方法に関し、より詳しくは、冷房運転と暖房運転とを同時にあるいは別々に行い得る冷暖房同時運転が可能な地熱を利用した冷暖房システム及びその制御方法に関する。   The present invention relates to a cooling / heating system using geothermal heat and a control method thereof, and more particularly to a cooling / heating system using geothermal heat capable of simultaneous cooling / heating operation capable of performing cooling operation and heating operation simultaneously or separately and a control method thereof. .

一般に、ヒートポンプは、蒸発器、圧縮機、凝縮器及び膨張弁がサイクルを構成し、その作動流体が液化と気化を繰り返しながら、冷暖房のための空間に設けられたファンコイルユニットの内部を流動する、さらに他の作動流体で熱を伝達することにより、冷暖房が行われるようにしていた。   In general, in the heat pump, an evaporator, a compressor, a condenser, and an expansion valve constitute a cycle, and the working fluid flows through a fan coil unit provided in a space for cooling and heating while repeating liquefaction and vaporization. In addition, cooling and heating are performed by transferring heat with another working fluid.

このようなヒートポンプは、生活排水の廃熱を熱源として使用する廃熱利用システム、または地中に埋設された地熱交換パイプを使用して冷暖房を行うようになっている地熱利用システムの主要な構成要素として使用される。   Such a heat pump is a main component of a waste heat utilization system that uses waste heat from domestic wastewater as a heat source, or a geothermal utilization system that uses a geothermal exchange pipe embedded in the ground to perform cooling and heating. Used as an element.

一般に、廃熱利用システムでは、風呂屋などから排水される生活排水の廃熱をヒートポンプの蒸発器の熱源として使用し、この熱を利用してヒートポンプの凝縮器で温水を生産する。   Generally, in a waste heat utilization system, waste heat from domestic wastewater discharged from a bathhouse or the like is used as a heat source for an evaporator of a heat pump, and hot water is produced by a heat pump condenser using this heat.

そして、地熱利用システムは、暖房時には地熱交換パイプから伝達される地熱をヒートポンプの蒸発器の熱源として使用し、この熱を利用してヒートポンプの凝縮器で温水を生産する。冷房時にはヒートポンプで発生する凝縮器の排熱を地熱交換パイプを通じて排出する。   And a geothermal utilization system uses the geothermal heat transmitted from a geothermal exchange pipe at the time of heating as a heat source of the evaporator of a heat pump, and produces warm water with a condenser of a heat pump using this heat. During cooling, exhaust heat from the condenser generated by the heat pump is discharged through a geothermal exchange pipe.

しかし、前記廃熱利用システムにおいては、熱源である生活排水の温度が低い場合に備えて、別の補助ボイラーをさらに設けなければならないという問題点があり、また前記地熱利用システムにおいては、冷房時にヒートポンプの凝縮器で発生する排熱の過多で地熱交換パイプの数が多くなったり、これを収容するための冷却塔をさらに設けなければならないという問題点があった。   However, in the waste heat utilization system, there is a problem that another auxiliary boiler must be provided in preparation for the case where the temperature of domestic wastewater, which is a heat source, is low. There is a problem that the number of geothermal exchange pipes is increased due to excessive waste heat generated in the condenser of the heat pump, and a cooling tower for accommodating this must be further provided.

このような問題点を解決するために、大韓民国実用新案登録第３３９３４９号には、ヒートポンプを地熱交換パイプ側とファンコイルユニット側とにそれぞれ取り付けて冷房運転と暖房運転とをそれぞれ別に行い、別の冷温水蓄熱槽をヒートポンプとファンコイルユニットとの間に置き、安い深夜電力を利用して冷暖房を行うようにした技術が開示されている（特許文献１参照）。   In order to solve such problems, Korean Utility Model Registration No. 339349 has a heat pump attached to each of the geothermal exchange pipe side and the fan coil unit side to perform cooling operation and heating operation separately. A technology has been disclosed in which a cold / hot water heat storage tank is placed between a heat pump and a fan coil unit, and air conditioning is performed using cheap midnight power (see Patent Document 1).

しかし、前記したような従来の技術においては、次のような問題点があった。   However, the conventional techniques as described above have the following problems.

前記大韓民国実用新案登録第３３９３４９号は、冷房と暖房とを同時に行うことができない。すなわち、冷房運転または暖房運転を選択的に行わなければならない。よって、アイスリンクのように、冷暖房運転が同時に行われなければならない場合には、冷房のためのシステムと暖房のためのシステムとを別に設ける必要があった。これは、結局、冷暖房のためのシステムの設置コストが高くなるという問題を招いていた。   The Korean Utility Model Registration No. 339349 cannot perform cooling and heating at the same time. That is, the cooling operation or the heating operation must be selectively performed. Therefore, when the cooling / heating operation has to be performed at the same time as in an ice rink, it is necessary to separately provide a cooling system and a heating system. This eventually led to a problem that the installation cost of the system for air conditioning became high.

そして、従来の技術においては、冷房運転時または暖房運転時に発生する廃熱が再生されず、殆ど捨てられていた。よって、冷暖房システムのエネルギー使用効率が相対的に低下するという問題点もあった。   In the prior art, the waste heat generated during the cooling operation or the heating operation is not regenerated and is almost discarded. Therefore, there also exists a problem that the energy use efficiency of an air conditioning system falls relatively.

また、従来の技術においては、ヒートポンプの動作に必要な地熱交換部が冷暖房システムの最高効率になるように設計されており、地熱交換部の設置に多くの空間を必要とするという問題があった。
大韓民国実用新案登録第３３９３４９号明細書 Moreover, in the conventional technology, the geothermal heat exchange part necessary for the operation of the heat pump is designed to have the highest efficiency of the air conditioning system, and there is a problem that a large amount of space is required for installing the geothermal heat exchange part. .

以下、本発明の好ましい実施の形態を、添付図面に基づいて詳しく説明する。   Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

図１は、本発明による冷暖房同時運転が可能な地熱を利用した冷暖房システムの好ましい実施例を示す系統図である。図示のように、ヒートポンプ１００は、蒸発器１１０と、圧縮機（図示せず）と、凝縮器１２０と、膨張弁（図示せず）とを備えている。前記蒸発器１１０と、圧縮機と、凝縮器１２０と、膨張弁とが構成するサイクルによって作動流体が流動される。前記作動流体は、ヒートポンプ１００の内部を流動し、気化と液化を繰り返しながら熱を伝達する。例えば、前記作動流体は、前記蒸発器１１０で蒸発しながら外部から熱を奪い取り、前記凝縮器１２０で凝縮しながら外部に熱を放出する。ちなみに、本実施例では、三つのヒートポンプ１００が使用されているが、その使用数は、これに限定されるものでなく、冷暖房の容量によって異なる。   FIG. 1 is a system diagram showing a preferred embodiment of an air-conditioning system using geothermal heat capable of simultaneous air-conditioning operation according to the present invention. As illustrated, the heat pump 100 includes an evaporator 110, a compressor (not shown), a condenser 120, and an expansion valve (not shown). The working fluid is caused to flow by a cycle constituted by the evaporator 110, the compressor, the condenser 120, and the expansion valve. The working fluid flows inside the heat pump 100 and transfers heat while repeating vaporization and liquefaction. For example, the working fluid takes heat from the outside while being evaporated by the evaporator 110 and releases heat to the outside while condensing by the condenser 120. Incidentally, in the present embodiment, three heat pumps 100 are used, but the number of uses is not limited to this, and varies depending on the capacity of the air conditioning.

前記蒸発器１１０と凝縮器１２０とには、前記ヒートポンプ１００の作動流体と熱交換する別の冷暖房の作動流体（以下、単に「冷暖房作動流体」と言う。）が通過する。ちなみに、前記ヒートポンプ１００で使用される作動流体の例として、ＨＦＣ−４０４Ａがあり、前記冷暖房作動流体の例として水がある。前記冷暖房作動流体は、前記ヒートポンプ１００の蒸発器１１０に連結される冷房パイプ１３０と、凝縮器１２０に連結される暖房パイプ１４０との内部を流動する。   The evaporator 110 and the condenser 120 pass through another cooling / heating working fluid (hereinafter simply referred to as “cooling / heating working fluid”) that exchanges heat with the working fluid of the heat pump 100. Incidentally, HFC-404A is an example of the working fluid used in the heat pump 100, and water is an example of the cooling / heating working fluid. The cooling / heating working fluid flows in the cooling pipe 130 connected to the evaporator 110 of the heat pump 100 and the heating pipe 140 connected to the condenser 120.

前記冷房パイプ１３０と暖房パイプ１４０との内部を冷暖房作動流体が円滑に流動するように、それぞれ冷房循環ポンプ１３２と暖房循環ポンプ１４２とが設けられる。前記冷房循環ポンプ１３２と暖房循環ポンプ１４２とは、冷暖房作動流体を加圧することで、冷房パイプ１３０と暖房パイプ１４０との内部に前記冷暖房作動流体をそれぞれ流動させる。   A cooling circulation pump 132 and a heating circulation pump 142 are respectively provided so that the cooling / heating working fluid smoothly flows in the cooling pipe 130 and the heating pipe 140. The cooling circulation pump 132 and the heating circulation pump 142 pressurize the cooling / heating working fluid to cause the cooling / heating working fluid to flow inside the cooling pipe 130 and the heating pipe 140, respectively.

前記冷房パイプ１３０と暖房パイプ１４０とは、それぞれ冷暖房用熱交換部１５０とヒートポンプ１００との間で冷暖房作動流体を流動させる。前記冷暖房用熱交換部１５０は、実際に冷暖房が必要な空間に設けられる。前記冷暖房用熱交換部１５０には、前記冷房パイプ１３０と連結される冷房用熱交換器１５２があり、前記暖房パイプ１４０と連結される暖房用熱交換器１５４がある。これらの冷房用熱交換器１５２と暖房用熱交換器１５４との代表的な例として、ファンコイルユニットが挙げられる。   The cooling pipe 130 and the heating pipe 140 cause the cooling / heating working fluid to flow between the cooling / heating heat exchanger 150 and the heat pump 100, respectively. The air conditioning unit 150 is provided in a space that actually requires air conditioning. The cooling / heating heat exchanger 150 includes a cooling heat exchanger 152 connected to the cooling pipe 130 and a heating heat exchanger 154 connected to the heating pipe 140. A typical example of the cooling heat exchanger 152 and the heating heat exchanger 154 is a fan coil unit.

前記冷房用熱交換器１５２と暖房用熱交換器１５４とは、それぞれ冷房または暖房のための空間に設けられる。よって、前記冷房用熱交換器１５２と暖房用熱交換器１５４とは、同じ空間に共に設けられても、また別の空間にそれぞれ設けられてもよい。例えば、冷房または暖房を選択する必要があるホテルルームやアイスリンクの観衆席のような空間には、冷房用熱交換器１５２と暖房用熱交換器１５４とが共に設けられる必要があり、またアイスリンクそのものには冷房用熱交換器１５２のみが設けられる必要がある。   The cooling heat exchanger 152 and the heating heat exchanger 154 are provided in a space for cooling or heating, respectively. Therefore, the cooling heat exchanger 152 and the heating heat exchanger 154 may be provided together in the same space or in different spaces. For example, in a room such as a hotel room or an ice rink seat where cooling or heating needs to be selected, both a cooling heat exchanger 152 and a heating heat exchanger 154 need to be provided, and ice Only the heat exchanger 152 for cooling needs to be provided in the link itself.

前記ヒートポンプ１００の蒸発器１１０及び凝縮器１２０にそれぞれ連結されるよう、地熱パイプ１６０が設けられる。前記地熱パイプ１６０の内部には、地熱作動流体が流動する。前記地熱作動流体は、前記ヒートポンプ１００の作動流体との間で行われる熱交換を前記蒸発器１１０または凝縮器１２０で行う。前記地熱パイプ１６０は、前記ヒートポンプ１００と後述する地熱交換部１７０との間で熱を伝達する地熱作動流体が流動する通路となる。前記地熱作動流体としては、水を使用することができる。前記地熱パイプ１６０には地熱循環ポンプ１６２が設けられる。前記地熱循環ポンプ１６２は、前記地熱作動流体を加圧して地熱パイプ１６０の内部を流動させる。   A geothermal pipe 160 is provided to be connected to the evaporator 110 and the condenser 120 of the heat pump 100, respectively. A geothermal working fluid flows in the geothermal pipe 160. The geothermal working fluid exchanges heat with the working fluid of the heat pump 100 by the evaporator 110 or the condenser 120. The geothermal pipe 160 serves as a passage through which a geothermal working fluid that transmits heat flows between the heat pump 100 and a geothermal exchange unit 170 described later. Water can be used as the geothermal working fluid. The geothermal pipe 160 is provided with a geothermal circulation pump 162. The geothermal circulation pump 162 pressurizes the geothermal working fluid to flow inside the geothermal pipe 160.

地熱交換部１７０は、地中に埋設される。前記地熱交換部１７０の例としては、地熱交換パイプがある。前記地熱交換部１７０は、前記地熱パイプ１６０を通じて伝達された地熱作動流体と地球との間で熱交換が行われるところである。   The geothermal exchange unit 170 is buried in the ground. An example of the geothermal exchange unit 170 is a geothermal exchange pipe. The geothermal exchange unit 170 is where heat is exchanged between the geothermal working fluid transmitted through the geothermal pipe 160 and the earth.

次に、図２は、本発明の他の実施例を示す図である。本実施例では、説明の便宜上、図１に示す実施例と同じ構成には同じ符号を付し、その説明を省略する。   Next, FIG. 2 is a diagram showing another embodiment of the present invention. In the present embodiment, for convenience of explanation, the same components as those in the embodiment shown in FIG.

本実施例では、前記ヒートポンプ１００の側から出る冷暖房作動流体が流れる冷房パイプ１３０が内部を貫通している氷蓄熱槽１８０を設けている。前記氷蓄熱槽１８０は、内部に熱貯蔵媒体(例えば、水)が設けられる。前記熱貯蔵媒体は、前記冷房パイプ１３０の内部を流動する冷暖房作動流体との熱交換により固体化することもある。すなわち、水の場合、氷になって熱を貯蔵する。   In the present embodiment, there is provided an ice heat storage tank 180 through which a cooling pipe 130 through which a cooling / heating working fluid exits from the heat pump 100 passes. The ice heat storage tank 180 is provided with a heat storage medium (for example, water). The heat storage medium may be solidified by heat exchange with a cooling / heating working fluid flowing inside the cooling pipe 130. That is, in the case of water, it becomes ice and stores heat.

前記氷蓄熱槽１８０を設けると共に、前記冷房パイプ１３０には、第１及び第２の切換弁１８１及び１８２を設けることで、冷房パイプ１３０の内部を流動する冷暖房作動流体を制御する。前記第１の切換弁１８１には、バイパスパイプ１８４が連結される。前記バイパスパイプ１８４は、冷暖房作動流体が氷蓄熱槽１８０を通過せず、ヒートポンプ１００から冷暖房用熱交換部１５０に伝達するようにしている。すなわち、前記第１の切換弁１８１の制御により冷暖房作動流体が前記氷蓄熱槽１８０を選択的に通過する。   The ice heat storage tank 180 is provided, and the cooling pipe 130 is provided with first and second switching valves 181 and 182 to control the cooling / heating working fluid flowing inside the cooling pipe 130. A bypass pipe 184 is connected to the first switching valve 181. The bypass pipe 184 transmits the cooling / heating working fluid from the heat pump 100 to the cooling / heating heat exchanger 150 without passing through the ice heat storage tank 180. That is, the air conditioning working fluid selectively passes through the ice heat storage tank 180 by the control of the first switching valve 181.

このように、氷蓄熱槽１８０を設けるのは、冷房と暖房とを交互に使用する場合に、冷房に必要なエネルギーを最小化するためである。すなわち、暖房の際にヒートポンプから出る廃熱を氷蓄熱槽１８０に貯蔵して置き、その後の冷房時に使用するようにしている。   Thus, the ice heat storage tank 180 is provided in order to minimize the energy required for cooling when cooling and heating are used alternately. In other words, waste heat from the heat pump during heating is stored and stored in the ice heat storage tank 180 for use in subsequent cooling.

図３は、本発明のさらに他の実施例を示す図である。本実施例では、説明の便宜上、図２に示す実施例と同じ構成には同じ符号を付し、その説明を省略する。   FIG. 3 is a diagram showing still another embodiment of the present invention. In the present embodiment, for convenience of explanation, the same components as those in the embodiment shown in FIG.

本実施例では、前記地熱パイプ１６０と地熱交換部１７０との間に補助熱交換部１９０をさらに設けている。前記補助熱交換部１９０の例としては、冷却塔が挙げられる。このような補助熱交換部１９０は、地熱作動流体の熱を外部に放出することで、地熱交換部１７０の容量を相対的に減らすことができる。すなわち、前記地熱交換部１７０を小型化してその設置に必要な空間を減らすことができる。   In this embodiment, an auxiliary heat exchange unit 190 is further provided between the geothermal pipe 160 and the geothermal exchange unit 170. An example of the auxiliary heat exchange unit 190 is a cooling tower. Such an auxiliary heat exchange unit 190 can reduce the capacity of the geothermal exchange unit 170 by releasing the heat of the geothermal working fluid to the outside. That is, the space required for the installation can be reduced by downsizing the geothermal exchange unit 170.

前記補助熱交換部１９０は、前記地熱交換部１７０とは別に設けられるもので、一般に地上や建物の屋上などに設けられる。前記補助熱交換部１９０は、前記地熱交換部１７０に流動される地熱作動流体と外部との熱交換を行い、前記地熱交換部１７０の容量を最小化する。   The auxiliary heat exchanging unit 190 is provided separately from the geothermal heat exchanging unit 170, and is generally provided on the ground or on the roof of a building. The auxiliary heat exchanging unit 190 exchanges heat between the geothermal working fluid flowing to the geothermal heat exchanging unit 170 and the outside, and minimizes the capacity of the geothermal heat exchanging unit 170.

以下、このような構成からなる、本発明による冷暖房同時運転が可能な地熱を利用した冷暖房システム及びその制御方法の作用を詳しく説明する。   Hereinafter, the operation of the cooling / heating system using the geothermal heat and the control method thereof according to the present invention, which can be operated simultaneously with cooling and heating, will be described in detail.

図４を参照して、図１に示す実施例の動作を説明する。先ず、暖房運転を説明すると、暖房運転では、前記ヒートポンプ１００が駆動し相対的に高温となった冷暖房作動流体が前記暖房パイプ１４０を通じて前記冷暖房熱交換部１５０に伝達されて暖房を行う。   The operation of the embodiment shown in FIG. 1 will be described with reference to FIG. First, the heating operation will be described. In the heating operation, the heat pump 100 is driven and a relatively high temperature cooling / heating working fluid is transmitted to the cooling / heating heat exchanging unit 150 through the heating pipe 140 to perform heating.

すなわち、前記地熱交換部１７０で地熱作動流体に地球から熱が伝達される。前記地熱作動流体は、前記ヒートポンプ１００の蒸発器１１０と連結されている地熱パイプ１６０に設けられた地熱循環ポンプ１６２により前記地熱パイプ１６０に沿って流動（移動）し、前記ヒートポンプ１００に伝達される。   That is, heat is transferred from the earth to the geothermal working fluid at the geothermal exchange unit 170. The geothermal working fluid flows (moves) along the geothermal pipe 160 by the geothermal circulation pump 162 provided in the geothermal pipe 160 connected to the evaporator 110 of the heat pump 100 and is transmitted to the heat pump 100. .

前記ヒートポンプ１００の蒸発器１１０で地熱作動流体とヒートポンプ１００の作動流体との間の熱交換が行われる。よって、ヒートポンプ１００の作動流体は、前記蒸発器１１０での熱交換により相対的に高温となる。前記ヒートポンプ１００の作動流体は、前記ヒートポンプ１００を構成するサイクルを循環し、前記凝縮器１２０に伝達される。前記凝縮器１２０で前記ヒートポンプ１００の作動流体は、凝縮しながら熱を放出し、前記暖房パイプ１４０に沿って流動する冷暖房作動流体に熱を供給する。   The evaporator 110 of the heat pump 100 exchanges heat between the geothermal working fluid and the working fluid of the heat pump 100. Therefore, the working fluid of the heat pump 100 becomes relatively high due to heat exchange in the evaporator 110. The working fluid of the heat pump 100 circulates through a cycle constituting the heat pump 100 and is transmitted to the condenser 120. In the condenser 120, the working fluid of the heat pump 100 releases heat while condensing, and supplies heat to the cooling / heating working fluid that flows along the heating pipe 140.

よって、前記冷暖房作動流体は、熱を吸収して相対的に高温となり、前記暖房循環ポンプ１４２により暖房パイプ１４０に沿って循環し、前記暖房用熱交換器１５４に伝達される。暖房運転の際の暖房用熱交換器１５４とヒートポンプ１００との間での冷暖房作動流体の流動が、矢印で示されている。前記暖房用熱交換器１５４で冷暖房作動流体は、熱交換により所定の空間を暖房する。   Therefore, the cooling / heating working fluid absorbs heat and becomes relatively high temperature, circulates along the heating pipe 140 by the heating circulation pump 142, and is transmitted to the heating heat exchanger 154. The flow of the cooling / heating working fluid between the heat exchanger 154 for heating and the heat pump 100 during the heating operation is indicated by arrows. In the heating heat exchanger 154, the cooling / heating working fluid heats a predetermined space by heat exchange.

次に、冷房運転の過程を説明する。冷房運転時にも前記ヒートポンプ１００は、暖房運転時と同様に動作する。すなわち、ヒートポンプ１００の作動流体は、サイクル内を同様に流動する。   Next, the process of the cooling operation will be described. Even during the cooling operation, the heat pump 100 operates in the same manner as during the heating operation. That is, the working fluid of the heat pump 100 flows similarly in the cycle.

そして、前記蒸発器１１０で熱交換され、相対的に低い温度の冷暖房作動流体が前記冷房パイプ１３０を通じて前記冷暖房用熱交換部１５０に伝達される。前記冷暖房用熱交換部１５０に伝達された冷暖房作動流体は、冷房用熱交換器１５２で熱交換し、所望の空間を冷房する。   Then, heat is exchanged in the evaporator 110, and a cooling / heating working fluid having a relatively low temperature is transmitted to the cooling / heating heat exchanger 150 through the cooling pipe 130. The cooling / heating working fluid transmitted to the cooling / heating heat exchanger 150 exchanges heat in the cooling heat exchanger 152 to cool a desired space.

このとき、前記ヒートポンプ１００の凝縮器１２０では、ヒートポンプ１００の作動流体から地熱作動流体に熱伝達が行われる。すなわち、前記ヒートポンプ１００の作動流体が凝縮されることによって出る熱は、前記地熱作動流体に伝達される。前記地熱作動流体は、前記凝縮器１２０と連結された地熱パイプ１６０に設けられた地熱循環ポンプ１６２の動作により前記地熱パイプ１６０に沿って流動し、前記地熱交換部１７０に伝達される。前記地熱交換部１７０では、前記地熱作動流体と地球との間の熱交換が行われる。冷房動作の際の前記冷房パイプ１３０の内部での冷暖房作動流体の流動が、図４に矢印で示されている。   At this time, in the condenser 120 of the heat pump 100, heat is transferred from the working fluid of the heat pump 100 to the geothermal working fluid. That is, the heat generated when the working fluid of the heat pump 100 is condensed is transferred to the geothermal working fluid. The geothermal working fluid flows along the geothermal pipe 160 by the operation of a geothermal circulation pump 162 provided in the geothermal pipe 160 connected to the condenser 120, and is transmitted to the geothermal exchange unit 170. In the geothermal exchange section 170, heat exchange is performed between the geothermal working fluid and the earth. The flow of the cooling / heating working fluid inside the cooling pipe 130 during the cooling operation is shown by arrows in FIG.

次に、冷暖房運転が同時に行われる過程を説明する。冷暖房運転が同時に行われる場合には、前記地熱交換部１７０は使用されない。すなわち、前記ヒートポンプ１００の駆動により前記凝縮器１２０から冷暖房作動流体に伝達された熱で暖房を行い、前記蒸発器１１０から冷暖房作動流体に伝達された熱で冷房を行う。   Next, a process in which the air conditioning operation is performed simultaneously will be described. When the cooling / heating operation is performed simultaneously, the geothermal exchange unit 170 is not used. That is, the heat pump 100 is driven to heat the heat transmitted from the condenser 120 to the cooling / heating working fluid, and the heat is transferred from the evaporator 110 to the cooling / heating working fluid.

すなわち、前記ヒートポンプ１００の作動流体が前記凝縮器１２０で凝縮することによって発生した熱は、前記暖房用熱交換器１５４と連結された暖房パイプ１４０の内部を流れる冷暖房作動流体に伝達され、前記冷暖房作動流体が暖房循環ポンプ１４２により流動され、暖房用熱交換器１５４で熱を所望する空間に供給して暖房を行う。   That is, heat generated by the working fluid of the heat pump 100 condensing in the condenser 120 is transmitted to the cooling / heating working fluid that flows inside the heating pipe 140 connected to the heating heat exchanger 154, and The working fluid is flowed by the heating circulation pump 142, and the heating heat exchanger 154 supplies heat to a desired space to perform heating.

そして、前記ヒートポンプ１００の作動流体が前記蒸発器１１０で蒸発しながら熱を吸収する。すなわち、前記冷房パイプ１３０の内部を流れる冷暖房作動流体から熱を奪い取る。このようになると、前記冷房パイプ１３０の内部を流れる冷暖房作動流体は、相対的に低い温度となり、前記冷房循環ポンプ１３２により流動され、前記冷房用熱交換器１５２で熱交換を行い、所望の空間を冷房する。   The working fluid of the heat pump 100 absorbs heat while evaporating in the evaporator 110. That is, heat is taken away from the cooling / heating working fluid flowing in the cooling pipe 130. In this case, the cooling / heating working fluid flowing inside the cooling pipe 130 has a relatively low temperature, is flowed by the cooling circulation pump 132, and performs heat exchange by the cooling heat exchanger 152, thereby obtaining a desired space. Cool the air.

次に、図５及び図６を参照して、図２に示す実施例の動作を説明する。図２に示す実施例で氷蓄熱槽１８０が使用されない場合には、冷房運転と暖房運転とは、図４での説明と同様に行われる。しかし、前記氷蓄熱槽１８０を使用するか、あるいは氷蓄熱槽１８０の媒体を固体化する場合には、前記地熱交換部１７０を使用しなくなる。勿論、このとき（氷蓄熱槽１８０が使用されない場合）は、前記冷房パイプ１３０の内部を流動する冷暖房作動流体が氷蓄熱槽１８０を通過せず、バイパスパイプ１８４を通過する。   Next, the operation of the embodiment shown in FIG. 2 will be described with reference to FIGS. When the ice heat storage tank 180 is not used in the embodiment shown in FIG. 2, the cooling operation and the heating operation are performed in the same manner as described with reference to FIG. However, when the ice heat storage tank 180 is used or the medium of the ice heat storage tank 180 is solidified, the geothermal exchange unit 170 is not used. Of course, at this time (when the ice heat storage tank 180 is not used), the cooling / heating working fluid flowing inside the cooling pipe 130 does not pass through the ice heat storage tank 180 but passes through the bypass pipe 184.

しかし、氷蓄熱槽１８０を使用する場合には、前記地熱交換部１７０を使用しなくてもよい。先ず、図５に矢印で示されているように、暖房運転を行うときは、ヒートポンプ１００の蒸発器１１０で冷房パイプ１３０の内部を流動する冷暖房作動流体が熱を奪い取られ、相対的に温度が低くなり、この冷暖房作動流体が前記氷蓄熱槽１８０の媒体を固体化する。このように、氷蓄熱槽１８０に熱を貯蔵するためには、前記第１の切換弁１８１は、バイパスパイプ１８４を通じては冷暖房作動流体が流動しないようにする。   However, when the ice heat storage tank 180 is used, the geothermal exchange unit 170 may not be used. First, as shown by the arrows in FIG. 5, when heating operation is performed, the cooling / heating working fluid that flows inside the cooling pipe 130 is deprived of heat by the evaporator 110 of the heat pump 100, and the temperature is relatively low. This cooling / heating working fluid solidifies the medium of the ice heat storage tank 180. Thus, in order to store heat in the ice heat storage tank 180, the first switching valve 181 prevents the cooling / heating working fluid from flowing through the bypass pipe 184.

すなわち、第１の切換弁１８１と第２の切換弁１８２とをそれぞれ制御し、冷暖房作動流体が蒸発器１１０から出て氷蓄熱槽１８０を経て再び蒸発器１１０に流入するようにする。これにより、暖房運転中に氷蓄熱槽１８０に熱を蓄積して冷房運転時に使用することができる。   That is, the first switching valve 181 and the second switching valve 182 are controlled so that the cooling / heating working fluid exits the evaporator 110 and flows again into the evaporator 110 through the ice heat storage tank 180. Thereby, heat can be accumulated in the ice heat storage tank 180 during the heating operation and can be used during the cooling operation.

図６は、前記氷蓄熱槽１８０の熱を利用して冷房運転を行う動作状態を示す図である。図示のように、前記冷房パイプ１３０の内部を流動する冷暖房作動流体は、前記氷蓄熱槽１８０を通過して前記冷房用熱交換器１５２に伝達され、前記冷房用熱交換器１５２を通過した後、前記ヒートポンプ１００の蒸発器１１０に流入される。このような冷暖房作動流体の流動は、冷房循環ポンプ１３２により行われ、前記ヒートポンプ１００の蒸発器１１０は、冷暖房作動流体がそのまま通過する。   FIG. 6 is a diagram illustrating an operation state in which the cooling operation is performed using the heat of the ice heat storage tank 180. As shown in the drawing, the cooling / heating working fluid flowing inside the cooling pipe 130 passes through the ice heat storage tank 180 and is transmitted to the cooling heat exchanger 152, and then passes through the cooling heat exchanger 152. , And flows into the evaporator 110 of the heat pump 100. Such a flow of the cooling / heating working fluid is performed by the cooling circulation pump 132, and the cooling / heating working fluid passes through the evaporator 110 of the heat pump 100 as it is.

このような方式により前記氷蓄熱槽１８０の熱が完全に無くなると、冷房運転のために、図４で説明したようにシステムを駆動させる。ちなみに、前記氷蓄熱槽１８０を使用して冷房運転を行う方法の一つとして、深夜電力を利用してもよい。すなわち、安い深夜電力を利用して氷蓄熱槽１８０の媒体を凍らせ、冷房運転が必要なときに使用することができる。   When the heat of the ice heat storage tank 180 is completely eliminated by such a method, the system is driven as described with reference to FIG. 4 for the cooling operation. Incidentally, midnight power may be used as one of the methods for performing the cooling operation using the ice heat storage tank 180. That is, the medium of the ice heat storage tank 180 can be frozen using cheap late-night power and used when cooling operation is required.

一方、図３に示す前記さらに他の実施例では、補助熱交換部１９０をさらに設けることで、地熱作動流体が地熱交換部１７０に伝達される前に、相対的に低い温度になる。これにより、地熱交換部１７０では、放出すべき熱を相対的に減らし、地熱交換部１７０の大きさを最小化することができる。   On the other hand, in the still another embodiment shown in FIG. 3, the auxiliary heat exchange unit 190 is further provided, so that the geothermal working fluid reaches a relatively low temperature before being transmitted to the geothermal exchange unit 170. Thereby, in the geothermal exchange part 170, the heat which should be discharge | released can be reduced relatively and the magnitude | size of the geothermal exchange part 170 can be minimized.

以上のように、上記実施の形態を参照して詳細に説明され図示されたが、本発明は、これに限定されるものでなく、このような本発明の基本的な技術的思想を逸脱しない範囲内で、当業界の通常の知識を有する者にとっては、他の多くの変更が可能であろう。また、本発明は、添付の特許請求の範囲により解釈されるべきであることは言うまでもない。   As described above, although described and illustrated in detail with reference to the above embodiment, the present invention is not limited to this and does not depart from the basic technical idea of the present invention. Many other modifications will be possible to those skilled in the art within the scope. Needless to say, the present invention should be construed in accordance with the appended claims.
