上記ガスエンジン２３には、伝達機構２３Ａを介して圧縮機２１と、図示しない伝達機構を介して発電機２４とが接続されており、このガスエンジン２３が駆動されると圧縮機２１と発電装置２４とが駆動される。従って、このガスエンジン２３の回転数によって圧縮機２１と発電機２４の回転数が決定され、つまり、当該エンジン駆動式空気調和装置１０の運転能力が決定される。このガスエンジン２３は、ＧＨＰコントローラ２８および系統連係パワコン６０によって運転が制御される。   The gas engine 23 is connected to a compressor 21 via a transmission mechanism 23A and a generator 24 via a transmission mechanism (not shown). When the gas engine 23 is driven, the compressor 21 and the power generation device are connected. 24 are driven. Accordingly, the rotational speeds of the compressor 21 and the generator 24 are determined by the rotational speed of the gas engine 23, that is, the operating capability of the engine-driven air conditioner 10 is determined. The operation of the gas engine 23 is controlled by a GHP controller 28 and a system linkage power conditioner 60.

なお、本実施形態では、圧縮機２１が一台の場合を例示しているが、これに限らず、複数台の圧縮機２１を電磁クラッチなどのクラッチ機構を介してガスエンジン２３に並列接続可能に設け、上記ガスエンジン２３で駆動させる圧縮機２１の組み合わせや台数を可変可能に構成してもよい。   In the present embodiment, the case where the number of the compressors 21 is one is illustrated. However, the present invention is not limited to this, and a plurality of compressors 21 can be connected in parallel to the gas engine 23 via a clutch mechanism such as an electromagnetic clutch. The combination and the number of compressors 21 driven by the gas engine 23 may be variable.

また、上記ガスエンジン２３には、水冷式エンジンが適用され、すなわち、上記ガスエンジン２３を冷却するための熱交換器１（１１）が備えられており、水回路Ｐ１に設置した温度センサＴ１で測定した冷却水温度が６０℃未満の場合は、電動弁Ａを閉めて、冷却水ポンプ１４を駆動して、冷却水を水回路Ｐ１、電動弁Ａ、水回路Ｐ２、逆止弁Ｃ１、水回路Ｐ３、冷却水ポンプ１４を経て循環してガスエンジン２３を冷却する。   Further, a water-cooled engine is applied to the gas engine 23, that is, a heat exchanger 1 (11) for cooling the gas engine 23 is provided, and a temperature sensor T1 installed in the water circuit P1 is used. When the measured cooling water temperature is less than 60 ° C., the motor-operated valve A is closed and the cooling water pump 14 is driven to supply the cooling water to the water circuit P1, the motor-operated valve A, the water circuit P2, the check valve C1, and the water.

水回路Ｐ１の冷却水温度が上昇して、例えば、温度センサＴ１で測定した６０℃を超えたら電動弁Ｂを開け、そして蓄熱槽７０に設置した温度センサＴ２で測定した７０℃を超えたら電動弁Ｂを閉めて、冷却水を水回路Ｐ４経て、電動弁Ｂ、水回路Ｐ５、熱交換器２（１３）、逆止弁Ｃ２、水回路Ｐ３、冷却水ポンプ１４を経て循環してガスエンジン２３を冷却する構成になっている。   When the temperature of the cooling water in the water circuit P1 rises and exceeds 60 ° C. measured by the temperature sensor T1, for example, the motor-operated valve B is opened, and when the temperature exceeds 70 ° C. measured by the temperature sensor T2 installed in the heat storage tank 70 The valve B is closed, and the cooling water is circulated through the water circuit P4, the motorized valve B, the water circuit P5, the heat exchanger 2 (13), the check valve C2, the water circuit P3, and the cooling water pump 14 to circulate the gas engine. 23 is cooled.

この冷却回路１（１５）内の冷却水は、ＧＨＰコントローラ２８の制御により電動弁Ａおよび電動弁Ｂの開閉、熱交換器２（１３）へ送風する送風ファン１２の駆動、電動式の冷却水ポンプ１４の駆動が制御され、冷却水ポンプ１４の駆動で冷却回路１（１５）内に循環されることにより、ガスエンジン２３の廃熱を吸熱させて熱交換器２（１３）で放熱させる。   The cooling water in the cooling circuit 1 (15) is controlled by the GHP controller 28 to open and close the motorized valves A and B, drive the blower fan 12 that blows air to the heat exchanger 2 (13), and motorized cooling water. The drive of the pump 14 is controlled and is circulated in the cooling circuit 1 (15) by the drive of the cooling water pump 14, so that the waste heat of the gas engine 23 is absorbed and radiated by the heat exchanger 2 (13).

発電機２４は、ガスエンジン２３により駆動されて三相交流電力を発電し、発電電力を整流器２６、ＤＣ／ＤＣコンバ−タＡ（２７）を経て系統連系パワコン６０に出力する。
系統連系パワコン６０は、発電機２３の発電出力量を可変制御するための発電制御用コントローラを内蔵しており、このコントローラにより可変制御された発電電力を商用系統５０に出力する。具体的には、系統連系パワコン６０は、発電機２３からの三相交流電力を、整流器２６、ＤＣ／ＤＣコンバ−タ２７を経て直流電力に変換した後、１００／２００Ｖの交流の様々な電力に変換して商用系統５０に出力する。 The generator 24 is driven by the gas engine 23 to generate three-phase AC power, and outputs the generated power to the grid interconnection power converter 60 via the rectifier 26 and the DC / DC converter A (27).
The grid interconnection power conditioner 60 incorporates a power generation control controller for variably controlling the power generation output amount of the generator 23, and outputs the generated power variably controlled by this controller to the commercial system 50. Specifically, the grid-connected power conditioner 60 converts the three-phase AC power from the generator 23 into DC power via the rectifier 26 and the DC / DC converter 27, and then converts various AC / DC power of 100 / 200V. It converts into electric power and outputs it to the commercial system 50.

この商用系統５０は、商用ＡＣ電源５１と需要家負荷（電力負荷）５２とを含み、需要家負荷５２は、商用系統５０の電力線に接続された照明負荷５２Ａ、ＯＡ（office automation）負荷５２Ｂの他に、空気調和装置１０の室外ユニット２０や室内ユニット３０による電力負荷を含んでいる。
また、この系統連系パワコン６０には、通信線を介して商用系統５０に設置された電流計（電力検出器）５３が接続される。この電流計５３は、商用系統５０の電力線に流れる電流値をリアルタイムに取得し、この取得したデータを系統連系パワコン６０に出力し、系統連系パワコン６０からＧＨＰコントローラ２８に通知される。 The commercial system 50 includes a commercial AC power source 51 and a consumer load (electric power load) 52. The consumer load 52 includes an illumination load 52A and an OA (office automation) load 52B connected to the power line of the commercial system 50. In addition, the electric load by the outdoor unit 20 and the indoor unit 30 of the air conditioning apparatus 10 is included.
In addition, an ammeter (power detector) 53 installed in the commercial system 50 is connected to the grid interconnection power conditioner 60 via a communication line. The ammeter 53 acquires the current value flowing through the power line of the commercial grid 50 in real time, outputs the acquired data to the grid interconnection power conditioner 60, and is notified from the grid interconnection power conditioner 60 to the GHP controller 28.

一方、蓄電ユニット４０は、断熱容器上蓋４５を装着した断熱容器４６中に収容された蓄電池４１と、各蓄電池４１間に充填した図示しない保温材と、蓄電池４１を作動温度まで加熱・維持するための底面用電気ヒ−タ４８と、蓄電池４１を充電する充電器４２、蓄電システムコントローラ４３、蓄電コントローラ４４、電極４９、ＤＣ／ＤＣコンバ−タＢ（２９）とを備えている。   On the other hand, the power storage unit 40 heats and maintains the storage battery 41 accommodated in the heat insulation container 46 fitted with the heat insulation container upper lid 45, the heat insulating material (not shown) filled between the storage batteries 41, and the storage battery 41 to the operating temperature. A bottom electric heater 48, a charger 42 for charging the storage battery 41, a power storage system controller 43, a power storage controller 44, an electrode 49, and a DC / DC converter B (29).

蓄電システムコントローラ４３および蓄電コントローラ４４の制御の下、充電器４２により商用系統５０の蓄電池４１を、例えば、図４に示したように午後２２：００時から午前８：００時の深夜の電力により充電させる。これによって、この蓄電池４１に発電電力を蓄えることができる。   Under the control of the power storage system controller 43 and the power storage controller 44, the charger 42 causes the storage battery 41 of the commercial system 50 to be driven by, for example, midnight power from 22:00 pm to 8:00 am as shown in FIG. Let it charge. Thereby, the generated power can be stored in the storage battery 41.

そして、停電の際や電圧変動あるはピーク電力の際などには蓄電システムコントローラ４３、蓄電コントローラ４４の制御の下、蓄電池４１からの電力をバックアップ電源として、ＤＣ／ＤＣコンバ−タＢ（２９）を経て系統連系パワコン６０で交流電力に変換されて、照明負荷５２Ａ、ＯＡ負荷５２Ｂ、室外ユニット２０や室内ユニット３０に供給される。   In the event of a power failure, voltage fluctuation, or peak power, the DC / DC converter B (29) uses the power from the storage battery 41 as a backup power source under the control of the power storage system controller 43 and the power storage controller 44. Then, the power is converted to AC power by the grid interconnection power conditioner 60 and supplied to the lighting load 52A, the OA load 52B, the outdoor unit 20 and the indoor unit 30.

なお、商用系統５０の停電や電圧変動あるはピーク電力などを検出するには、系統連系パワコン６０内のコントローラを電流計（電力検出器）５３の検出結果から停電などを検出する検出部として機能させてもよいし、あるいは蓄電ユニット４０の蓄電システムコントローラ４３などにこれらを検出する機能を持たせるようにしてもよい。
さらに、系統連系パワコン６０、蓄電システムコントローラ４３および蓄電コントローラ４４に、予め指定された時間に蓄電池４１に蓄電された電力を商用系統５０に出力されるスケジュール機能を持たせることもできる。
これにより、例えば、図５に示すように午後１２時から１５時の間などの電力ピーク時間帯に蓄電池４１に蓄電された電力を商用系統５０に出力させることにより、電力ピークカットが可能になる。 In order to detect a power failure, voltage fluctuation, or peak power of the commercial system 50, the controller in the grid connection power conditioner 60 is used as a detection unit that detects a power failure from the detection result of the ammeter (power detector) 53. You may make it function, or may make the electrical storage system controller 43 of the electrical storage unit 40, etc. have the function to detect these.
Furthermore, the grid interconnection power conditioner 60, the power storage system controller 43, and the power storage controller 44 may be provided with a schedule function for outputting the power stored in the storage battery 41 to the commercial system 50 at a predetermined time.
Thereby, for example, as shown in FIG. 5, the power peak cut can be performed by causing the commercial grid 50 to output the power stored in the storage battery 41 during the power peak time period such as from 12:00 to 15:00.

系統連系パワコン６０は、このエンジン駆動式空気調和装置１０全体を制御する制御装置として機能し、大別すると、室内ユニット３０に接続されたリモートコントローラ（不図示）からのユーザ指示に応じて空調運転の開始／停止などを行う空調制御と、ガスエンジン２３が駆動される間、発電機２３の発電出力量を可変制御する発電制御などを行う。
図６は、ＧＨＰ運転ＯＮ（上側）とＧＨＰ停止ＯＦＦ（下側）を行った際に、それに対応させて発電機２４による発電をＯＮ、ＯＦＦさせた状態を説明する説明図である。 The grid-connected power conditioner 60 functions as a control device that controls the entire engine-driven air conditioner 10, and is roughly classified according to a user instruction from a remote controller (not shown) connected to the indoor unit 30. Air conditioning control for starting / stopping the operation and power generation control for variably controlling the power generation output amount of the generator 23 while the gas engine 23 is driven are performed.
FIG. 6 is an explanatory diagram for explaining a state in which power generation by the generator 24 is turned on and off in response to GHP operation ON (upper side) and GHP stop OFF (lower side).

次に蓄電ユニット４０について図１および図２により説明する。
冷却回路１（１５）の冷却水温度が、例えば蓄熱槽７０に設置した温度センサＴ２で測定した冷却水温度７０℃未満である場合は、電動弁Ｂを開け、この冷却水を冷却回路２（１６）の水回路Ｐ６へ供給する。
冷却水を冷却回路２（１６）の水回路Ｐ６を経て、一旦蓄熱槽７０に蓄え、蓄熱槽７０に蓄えた冷却水を水回路Ｐ６を経て図２に示す断熱容器上蓋４５を装着した断熱容器４６中に収容された蓄電池４１の周囲を取り囲むように構成して配設した放熱器７１へ供給する。
放熱器７１は熱交換器として構成されており、放熱器７１により蓄電器４１が加熱される。放熱器７１をでた冷却水は逆止弁Ｃ４、Ｃ５を経て冷却回路２（１６）の水回路Ｐ７を流れ、そしてこの冷却水はさらに冷却回路１（１５）の水回路Ｐ３、冷却水ポンプ１４を経てガスエンジン２３を冷却し、この冷却水は循環して使用する構成になっている。 Next, the power storage unit 40 will be described with reference to FIGS. 1 and 2.
When the cooling water temperature of the cooling circuit 1 (15) is lower than the cooling water temperature of 70 ° C. measured by, for example, the temperature sensor T2 installed in the heat storage tank 70, the motor-operated valve B is opened and the cooling water is supplied to the cooling circuit 2 ( 16) to the water circuit P6.
The cooling water is stored in the heat storage tank 70 once through the water circuit P6 of the cooling circuit 2 (16), and the cooling water stored in the heat storage tank 70 is passed through the water circuit P6 and is provided with the heat insulating container upper lid 45 shown in FIG. 46 is supplied to a radiator 71 configured and arranged so as to surround the periphery of the storage battery 41 accommodated in 46.
The radiator 71 is configured as a heat exchanger, and the condenser 41 is heated by the radiator 71. The cooling water from the radiator 71 flows through the check circuit C4, C5 and the water circuit P7 of the cooling circuit 2 (16), and this cooling water is further supplied to the water circuit P3 of the cooling circuit 1 (15), the cooling water pump. 14, the gas engine 23 is cooled, and this cooling water is circulated for use.

蓄電池４１は、固体電解質型あるいは溶融塩型蓄電池などは作動温度が２５０〜４００℃の高温度であるので、特に充電時や常温から昇温する場合には断熱材などによる保温および放熱器７１による加熱だけでは不十分であり、底面用電気ヒ−タ４８を作動させて作動温度に加熱しそして維持する。   Since the storage battery 41 is a solid electrolyte type or molten salt type storage battery having a high operating temperature of 250 to 400 ° C., especially when charging or when the temperature is raised from room temperature, the heat storage by a heat insulating material or the like and the radiator 71 Heating alone is not sufficient and the bottom heater 48 is activated to heat and maintain the operating temperature.

図７は放熱器７１による加熱および底面用電気ヒ−タ４８による加熱により蓄電池４１を作動温度まで加熱・維持する状況の例を説明する説明図である。
この例では、充電する前は蓄電池４１が常温の状態にあり、まず放熱器７１による加熱を行うと蓄電池４１の温度が上昇し６０℃前後になる。蓄電池４１の温度が６０℃前後になったら、底面用電気ヒ−タ４８による加熱により蓄電池４１を３００℃前後の作動温度まで加熱・維持することを示している。
底面用電気ヒ−タ４８による加熱の間も放熱器７１による補助的加熱を行って蓄電池４１を作動温度に加熱・維持することをサポートする。 FIG. 7 is an explanatory diagram for explaining an example of a situation in which the storage battery 41 is heated and maintained up to the operating temperature by heating by the radiator 71 and heating by the electric heater 48 for the bottom surface.
In this example, the storage battery 41 is in a normal temperature state before charging, and when the radiator 71 is first heated, the temperature of the storage battery 41 rises to about 60 ° C. When the temperature of the storage battery 41 reaches around 60 ° C., the storage battery 41 is heated and maintained to an operating temperature of around 300 ° C. by heating with the electric heater 48 for the bottom surface.
During heating by the bottom electric heater 48, auxiliary heating by the radiator 71 is performed to support heating and maintaining the storage battery 41 at the operating temperature.

蓄電ユニット４０の前記運転は、主として蓄電システムコントローラ４３および蓄電コントローラ４４の制御の下に行われる。前記のように、例えば、図４に示したように午後２２：００時から午前８：００時の深夜の電力により充電器４２により蓄電池４１を充電することができる。   The operation of the power storage unit 40 is mainly performed under the control of the power storage system controller 43 and the power storage controller 44. As described above, for example, as illustrated in FIG. 4, the storage battery 41 can be charged by the charger 42 with the power of midnight from 22:00 pm to 8:00 am.

蓄熱槽７０は保温性がよく多量（例えば３００リットル）の冷却水を蓄えることができるものであれば、材質や構造などは特に限定されるものではなく、市販のものを使用することができる。
蓄熱槽７０の他の例として内部に図示しない加熱手段を備えたものを挙げることができる。この場合は加熱手段により冷却水を加熱して温度センサＴ２により温度を検出して所定の温度に制御して蓄熱槽７０から水回路Ｐ６を経て放熱器７１へ供給する。
冷却水を水回路Ｐ６に設けた蓄熱槽７０に一旦蓄えることにより、蓄熱槽７０はクッションの役を果たし、冷却水の量的変化や温度変化を抑え、所定の冷却水量を確保したり一定温度にできるのでガスエンジン２３の冷却と蓄電器４１の加熱をともにより良好に行うことができる。 The heat storage tank 70 is not particularly limited in material and structure as long as it has good heat retention and can store a large amount (for example, 300 liters) of cooling water, and a commercially available one can be used.
Another example of the heat storage tank 70 may include a heating unit (not shown) provided inside. In this case, the cooling water is heated by the heating means, the temperature is detected by the temperature sensor T2, is controlled to a predetermined temperature, and is supplied from the heat storage tank 70 to the radiator 71 through the water circuit P6.
By temporarily storing the cooling water in the heat storage tank 70 provided in the water circuit P6, the heat storage tank 70 serves as a cushion, suppresses a change in the quantity and temperature of the cooling water, and secures a predetermined amount of cooling water or a constant temperature. Therefore, the cooling of the gas engine 23 and the heating of the battery 41 can be performed more satisfactorily.

放熱器７１は熱交換性および耐腐食性が高く、耐久性の優れたものであれば、材質や構造などは特に限定されるものではなく、市販のものを使用することができる。   As long as the heat radiator 71 has high heat exchange and corrosion resistance and is excellent in durability, the material and structure are not particularly limited, and commercially available ones can be used.

(29) and the system linkage power conditioner 60 are operated, and the electric heater 48 is not operated.

表１に示すように、空気調和装置１０の夜間（２２：００〜８：００）の運転時には、ガスエンジン２３、圧縮機２１、発電機２４、冷却水ポンプ１４を作動させ、電動弁Ａは温度センサＴ１で検出した温度がＴ１＞６０℃であれば開とし、Ｔ１＜６０℃であれば閉とし、電動弁Ｂは温度センサＴ２で検出した温度がＴ２＞７０℃であれば閉とし、Ｔ２＜７０℃であれば開とし、充電器４２は使用せず、蓄電器４１は必要に応じて放電し、ＤＣ／ＤＣコンバ−タＡ（２７）および系統連係パワコン６０は作動させるが、電気ヒータ４８は作動させない。   As shown in Table 1, when the air conditioner 10 is operated at night (22:00 to 8:00), the gas engine 23, the compressor 21, the generator 24, and the cooling water pump 14 are operated. If the temperature detected by the temperature sensor T1 is T1> 60 ° C., the valve is opened, and if T1 <60 ° C., the valve is closed.
