ハウス２は、内部に植物１２を栽培する為の培地９を設けており、この培地９を囲むようにして培地改善手段１０及び電照制御手段１１を設置してある。   The house 2 is provided with a medium 9 for cultivating the plant 12 therein, and a medium improving means 10 and an illumination control means 11 are installed so as to surround the medium 9.

培地９は、いちご、メロン、ニラ等の農作物や花類、即ち、植物１２を栽培する為に調整された液状又は固形の培養基となるものであり、土壌及び水耕のいずれの場合もある。本例では土壌の場合として説明し、その培地９には上記植物１２が栽培中である場合とする。   The culture medium 9 is a liquid or solid culture medium prepared for cultivating crops and flowers such as strawberries, melons, and leek, that is, plants 12, and may be either soil or hydroponics. In this example, the case of soil is described, and it is assumed that the plant 12 is being cultivated in the medium 9.

培地改善手段１０は、培地９に培養液を供給する培養液供給手段１３と、コージェネレーション設備１からの熱で培地９の温度を植物の栽培に適切な温度に加温する培地加温手段１４とを備える。培地温度の調整は、温度センサ１９とコンピュータ３の制御によって可能となる。   The medium improving means 10 includes a medium supplying means 13 for supplying a medium to the medium 9 and a medium heating means 14 for heating the temperature of the medium 9 to a temperature suitable for plant cultivation by heat from the cogeneration facility 1. With. The medium temperature can be adjusted by controlling the temperature sensor 19 and the computer 3.

培養液供給手段１３は、培養液タンク１５内に貯蔵されている液化肥料等の培養液を培養液供給パイプ１６ａを介して培地９内に送り込むものである。又、培養液供給パイプ１６ａの途中には培養液タンク１５から培養液を培地９内に送るための培養液用ポンプ１７が設けられている。   The culture solution supply means 13 sends a culture solution such as liquefied fertilizer stored in the culture solution tank 15 into the medium 9 through the culture solution supply pipe 16a. A culture solution pump 17 for sending the culture solution from the culture solution tank 15 into the medium 9 is provided in the middle of the culture solution supply pipe 16a.

培地加温手段１４は、コージェネレーション設備１で生産された熱を、培地加温用パイプ１６ｂを通して培地９内に送り込むものである。培地加温手段１４には、培地９や周辺の雰囲気温度を検出する温度センサ１９と、当該温度センサ１９で検出された温度に応じて、コージェネレーション設備１から培地加温手段１４に送り込まれる熱量を、コンピュータ３の制御の下で調整する為の調整バルブ２０を設けている。   The culture medium heating means 14 sends the heat produced by the cogeneration facility 1 into the culture medium 9 through the culture medium heating pipe 16b. The culture medium heating means 14 includes a temperature sensor 19 that detects the ambient temperature of the culture medium 9 and the surroundings, and the amount of heat that is sent from the cogeneration facility 1 to the culture medium heating means 14 according to the temperature detected by the temperature sensor 19. Is provided under the control of the computer 3.

電照制御手段１１は、培地９で栽培中の植物１２に対して人口照明を行うものであり、複数の照明具２１を有している。この電照制御手段１１は、コンピュータ３の下で許可された時間だけ植物１２に人口光を照射し、該植物１２に対して花卉分化等の日長反応の制御を行う。   The illumination control means 11 performs artificial illumination on the plant 12 that is being cultivated in the culture medium 9, and has a plurality of lighting fixtures 21. This illumination control means 11 irradiates the plant 12 with artificial light for the time allowed under the computer 3 and controls the day length reaction such as floret differentiation on the plant 12.

従って、この実施例のように構成されたエネルギー供給システムでは、次のような作用・効果が期待できる。
（１）ガス燃料でコージェネレーション設備１を運転させて電力と熱を生産し、ここで生産された電力をハウス２内の電照制御手段の照明具２１の照明用電力、培養液タンク１５内に蓄えられている培養液を培養液供給手段１３を構成する培養液供給パイプ１６ａを通して培地９に送り込む培養液用ポンプ１７の電力、及び、ＣＯ2 供給ダクト５ｂ内に二酸化炭素ガスを強制的に送り込むファン７を駆動する電力等として使用し、消費することができる。よって、商用電源２３を使用しなくてもよいので、商用電源２３がきていない地域においてもシステムの使用が可能である。尚、商用電源２３を利用できる場所では、系統連系制御装置２４によって商用電源２３を共用することも可能であり、共用した場合では電力の過不足が生じても自動的に電力会社の電力で補完され、安定した電力供給を得ることができる。
（２）生産された熱は、培地加温用パイプ１６ｂを通して培地９に送り込まれて消費し、培地９を植物１２の育成に適した温度にして好熱性微生物並びにその酵素の活性化を図り、代謝後の不要となった組織・成分並びに病原菌を分解することができるので、植物１２の育成効率化が図れる。
（３）生産された熱は、培地９内に存在する雑菌を殺菌するのに使用することもできる。即ち、該殺菌に必要な温度に加温された熱を培地加温用パイプ１６ｂを通し、培地殺菌処理手段２５を用いて前記培地９内に存在する雑菌の殺菌処理が実行される。而して、この殺菌処理は、植物１２の栽培がなされていない時期に実施される。又、前記殺菌に必要な温度の調整は前記コンピュータ３の制御によって実施されるようにしてもよい。更に又、培養液内に混入された殺菌剤或いは微生物資材を使用して病原性微生物の繁殖を抑制することも可能である。この場合は、植物１２の栽培が行われている間においても実施できる。之等の方法を併用することにより、殺菌剤等の農薬の使用量を節減でき、或いは無農薬による栽培も可能となる。
（４）電照制御手段１１により、例えばイチゴ、メロン、菊、ニラ等の植物１２に対し、花卉分化等の日長反応の制御を行うために、比較的低出力の人口照明を行い、日長を人為的に調整して栽培する電照栽培を行うことにより植物の育成を効率的に行うことができる。
（５）ガス燃料を燃やすことによって発生する二酸化炭素ガスは、ＣＯ2 供給ダクト５ｂを通してハウス２内に供給されるので、大気中に放出される二酸化炭素ガスが低減し、環境汚染の改善が図られる。尚、ハウス２内に放出された二酸化炭素ガスは植物の代謝のために活用され、活性化されて浄化される。又、ハウス２内に放出される二酸化炭素ガスは、コンピュータ３の制御により必要な時間帯に自動的に供給されるようにしてある。
（６）システム全体の制御は、コンピュータ３を使用して自動制御が可能であるので、生産者が高齢者や不慣れな者であっても作業負加を軽くすることができる。
（７）尚、本発明は、本発明の精神を逸脱しない限り種々の改変を為すことができ、そして、本発明が該改変されたものに及ぶことは当然である。 Therefore, in the energy supply system configured as in this embodiment, the following actions and effects can be expected.
(1) The cogeneration facility 1 is operated with gas fuel to produce electric power and heat, and the electric power produced here is used for the illumination power of the lighting device 21 of the illumination control means in the house 2 and in the culture medium tank 15. The culture medium stored in the medium is forced into the culture medium pump 17 for supplying the culture medium 9 through the culture medium supply pipe 16a constituting the culture medium supply means 13 and the carbon dioxide gas into the CO 2 supply duct 5b. It can be used and consumed as power to drive the fan 7 to be sent. Therefore, since it is not necessary to use the commercial power source 23, the system can be used even in an area where the commercial power source 23 does not come. In a place where the commercial power supply 23 can be used, the commercial power supply 23 can also be shared by the grid interconnection control device 24. Complementary and stable power supply can be obtained.
(2) The produced heat is sent to the medium 9 through the medium heating pipe 16b and consumed, and the medium 9 is brought to a temperature suitable for growing the plant 12 to activate the thermophilic microorganism and its enzyme. Since tissue / components and pathogens that are no longer required after metabolism can be decomposed, the growth efficiency of the plant 12 can be improved.
(3) The produced heat can also be used to sterilize germs present in the culture medium 9. That is, the heat heated to the temperature necessary for sterilization is passed through the medium heating pipe 16b, and the sterilization process of the germs existing in the medium 9 is executed using the medium sterilization processing means 25. Thus, this sterilization treatment is performed when the plant 12 is not cultivated. Further, the adjustment of the temperature necessary for the sterilization may be performed under the control of the computer 3. Furthermore, it is also possible to suppress the propagation of pathogenic microorganisms using a bactericide or microbial material mixed in the culture solution. In this case, it can be carried out while the plant 12 is being cultivated. By using these methods together, the amount of agricultural chemicals such as bactericides can be reduced, or cultivation without agricultural chemicals is possible.
(4) The lighting control means 11 performs, for example, artificial lighting with relatively low output to control plants such as strawberry, melon, chrysanthemum, leek, etc. Plant growth can be performed efficiently by performing electric lighting cultivation in which the length is artificially adjusted.
(5) Since carbon dioxide gas generated by burning gaseous fuel is supplied into the house 2 through the CO 2 supply duct 5b, the carbon dioxide gas released into the atmosphere is reduced, and environmental pollution is improved. It is done. The carbon dioxide gas released into the house 2 is utilized for plant metabolism and is activated and purified. The carbon dioxide gas released into the house 2 is automatically supplied at a necessary time zone under the control of the computer 3.
(6) Since the control of the entire system can be automatically controlled using the computer 3, even if the producer is an elderly person or an unaccustomed person, the work load can be reduced.
(7) It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
