〔産業上の利用分野〕
本発明は、植物の栽培等に使用される温室などの温度を
調整するのに適する冷暖房システムに関するものである
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heating and cooling system suitable for adjusting the temperature of a greenhouse or the like used for cultivating plants.
施設園芸用温室などには太陽熱集積機能があり、この熱
量は普通の野菜を栽培するのに必要とする暖房熱量に匹
敵することが知られている。そのため、温室で植物を栽
培することが行なわれているが、従来は多すぎる熱量は
、温室の一部を開放して熱を室外に放出するとか、温室
の一部を覆うなどして集熱しないようにしている。It is known that greenhouses for greenhouse horticulture have a solar heat collection function, and the amount of heat generated is comparable to the amount of heating heat required to grow ordinary vegetables. For this reason, plants are grown in greenhouses, but conventionally, too much heat has been collected by either opening part of the greenhouse to release the heat outside, or covering part of the greenhouse to collect heat. I try not to.
また、雨天の時や冬期などの日照時間が短く、室内の温
度が所定の温度に達しないときには、室内を暖房してい
る場合もある。In addition, when the daylight hours are short and the indoor temperature does not reach a predetermined temperature, such as during rainy weather or winter, the indoor room may be heated.
しかして、植物の栽培のように室内を高炭酸ガス量とし
ているような場合には、開放することによってその利点
が失われるし、また熱量が無駄になるという問題がある
。更に、暖房したのでは、燃費がかかるという別な問題
を生じる。However, in cases where the indoor air contains a high amount of carbon dioxide gas, such as when cultivating plants, opening the room will lose its benefits and cause the problem of wasted heat. Furthermore, heating the room causes another problem in that it costs more fuel.
本発明の温室等の冷暖房システムは、上記問題を解決す
るために、温室等の集熱機能を有する室と、ヒートポン
プと、熱交換器と、蓄熱水槽とからなる構成としたこと
を特徴とする。In order to solve the above-mentioned problems, the heating and cooling system for a greenhouse, etc. of the present invention is characterized in that it is configured to include a room having a heat collection function, such as a greenhouse, a heat pump, a heat exchanger, and a heat storage water tank. .
本発明において、温室等の集熱機能を有する室とは、従
来の温室そ、のもでよく、野菜等の栽培等に使用されて
いる温室そのものでよい。In the present invention, the room having a heat collecting function such as a greenhouse may be a conventional greenhouse, or may be a greenhouse itself used for cultivating vegetables and the like.
ヒートポンプは、低温の熱源（水、空気など）から熱を
吸収して、高温の熱源（暖房などの熱源）に熱を与える
装置であり、暖房および冷房に使用できるものである。A heat pump is a device that absorbs heat from a low-temperature heat source (water, air, etc.) and provides heat to a high-temperature heat source (heat source such as a heating source), and can be used for heating and cooling.
温室は太陽熱を集熱できる機能を有することから、日中
温室で得られる熱をヒートポンプまたは熱交換器で吸収
し、この熱を蓄熱水槽の水に蓄熱させる。この水に蓄熱
させた熱を夜間の暖房用熱源として使用する。ヒートポ
ンプ単独の暖房システムとせず、熱交換器との組合せシ
ステムとすることによってヒートポンプ単独の暖房シス
テムの効率よりもずっと高い効率を得ることができる。Since greenhouses have the ability to collect solar heat, the heat obtained in the greenhouse during the day is absorbed by a heat pump or heat exchanger, and this heat is stored in water in a heat storage tank. The heat stored in this water is used as a heat source for nighttime heating. By using a combined system with a heat exchanger rather than using a heat pump alone, it is possible to obtain much higher efficiency than a heating system using only a heat pump.
本発明において、蓄熱水槽は１個のみ設ける必要はなく
、場合により２個以上設けてもよい。ヒートポンプを作
動させたときに生ずる熱を、それぞれ冷水、温水として
別々の水槽に蓄熱し、必要に応じてヒートポンプまたは
熱交換器で放熱するようにする。In the present invention, it is not necessary to provide only one heat storage water tank, and two or more may be provided depending on the case. The heat generated when the heat pump is operated is stored in separate water tanks as cold water and hot water, respectively, and is radiated by the heat pump or heat exchanger as necessary.
このようにすることにより、昼間、温室内の温度が高く
なり冷房が必要な時、ヒートポンプで熱を吸収するか、
冷水蓄熱水槽の冷熱を熱交換器で放出することによって
温室内の温度を調節することができる。雨天などで暖房
を必要とするときは、上記と反対の操作によって温室内
を加温できる。この場合、ヒートポンプの熱源は蓄熱水
槽の熱を利用してもよいし、屋外の空気に求めてもよい
。By doing this, when the temperature inside the greenhouse becomes high during the day and cooling is required, the heat pump can absorb the heat or
The temperature inside the greenhouse can be adjusted by releasing the cold heat from the cold water storage tank using a heat exchanger. When heating is required due to rainy weather, the inside of the greenhouse can be heated by doing the opposite of the above. In this case, the heat source of the heat pump may be the heat of the heat storage water tank or may be obtained from the outdoor air.
さらに、夏期夜間の過高温をヒートポンプの冷却機能を
利用して下げることにより、野菜類の成育を促進するこ
ともできる。Furthermore, the growth of vegetables can be promoted by using the cooling function of the heat pump to lower excessively high temperatures during summer nights.
以下、本発明の実施例を図面にしたがって説明する。 Embodiments of the present invention will be described below with reference to the drawings.

はヒートポンプ、７は膨張弁を示す。The figure is a schematic diagram showing one embodiment of the present invention, where l is a greenhouse and 6
indicates a heat pump, and 7 indicates an expansion valve.
昼間温室内の空気が十分に暖いときは、水−空気熱交換
器２によって蓄熱水槽３に蓄熱する。When the air in the greenhouse is sufficiently warm during the day, heat is stored in the heat storage water tank 3 by the water-air heat exchanger 2.
また、雨天などあ気象条件により温室内の空気が十分に
暖まらないときは、ヒートポンプ６によって冷媒−空気
熱交換器４およびｂを介して、外気から集熱して蓄熱水
槽３に蓄熱する。When the air in the greenhouse is not sufficiently warmed due to weather conditions such as rain, the heat pump 6 collects heat from the outside air via the refrigerant-air heat exchangers 4 and b and stores it in the heat storage water tank 3.
一方、夜間には水−空気熱交換器２またはヒートポンプ

てもよい。On the other hand, at night, the air in the greenhouse is heated by the heating function of the water-air heat exchanger 2 or the heat pump 6. Note that 8 in the figure indicates a pipe for refrigerant, etc. As the water-air heat exchanger 2, a radiator that is normally used indoors for heating and cooling may be used. Moreover, depending on the case, piping may be installed in a hydroponic bed installed in a greenhouse to serve as a water-water heat exchanger.
本発明は上記のような構成としたため、温室内の温度を

きる。Since the present invention has the above configuration, the temperature inside the greenhouse can be easily controlled regardless of the weather, daytime, or nighttime. In addition, heat pumps can be operated at times when electricity prices are low, such as at night, to store heat. Therefore, plants such as vegetables can be produced inexpensively and stably.
