Abstract

PROBLEM TO BE SOLVED: To solve the limitation with a conventional power generation system using a medium of low boiling point in which the temperature of hot water of a hot spa or the temperature difference of sea water is used, wherein in the hot spa system, it is only installed in a place having such a hot spa, while the system using the temperature difference of sea water has a limitation that the place of installation of the system must be close to the ocean, and its scale is increased.SOLUTION: A so-called household solar water heater (including heaters using medium other than water) is used as a heat source of the low boiling-point medium power generation. This heater can solve the restriction of the place of the hot spa system, and also solves the restriction that the scale of the sea water temperature difference system is large, the cost for the installation itself of its facility becomes large, and the hot spa system is installed only in a vicinity of the sea, and less usable for individual use or for stores on small scale.

Description

本発明は、所謂、太陽熱温水器を使用した低沸点媒体による、発電方式に関する。The present invention relates to a power generation method using a low boiling point medium using a so-called solar water heater.

従来の低沸点媒体を使用した発電は、温泉の湯温や海水の温度差を利用した方式があるが、温泉方式は、温泉が沸いている箇所にしか設置出来ない。また、海水の温度差を利用した方式は、温泉同様に、設置場所の制約や、その装置の規模が大きくなると云う制約があった。Conventional power generation using a low-boiling point medium uses a hot spring temperature or a temperature difference between seawater, but the hot spring method can be installed only at a location where the hot spring is boiling. In addition, the method using the temperature difference between seawater, like hot springs, has restrictions on the installation location and the size of the device.

以上に述べた従来の低沸点媒体を利用した発電方式は、設置場所の制約や規模が大きくなることにより、個人や小規模店舗等では、利用が困難である。The conventional power generation method using a low-boiling-point medium described above is difficult to use in individuals, small stores, and the like due to restrictions on the installation location and large scale.

本発明は、太陽熱温水器（水以外の媒体を利用したものを含む）を利用することにより、設置場所の制約が少なく、費用も比較的安価で製作出来る。場所の制約が少なく、安価な投資で、発電を実現することを目的とするものである。The present invention uses a solar water heater (including one using a medium other than water), and can be manufactured with less restrictions on the installation location and at a relatively low cost. The purpose of this project is to realize power generation with few restrictions on the location and low cost investment.

問題を解決するための手段Means to solve the problem

そして、本発明は上記の目的を達成するため、既に実用化、社会的に普及している太陽熱温水器（水以外の媒体を利用したものを含む）で発生させた温水温度により、低沸点媒体を沸騰させ、その上記で発電を行う装置である。In order to achieve the above-mentioned object, the present invention achieves the above-described purpose by using a hot water temperature generated by a solar water heater (including one using a medium other than water) that has already been put into practical use and socially spread. Is a device for generating electricity by boiling the above.

発明の効果The invention's effect

上述したように本発明は従来の温泉や海水の温度差を利用することなく、安価な発電装置を提供できる。As described above, the present invention can provide an inexpensive power generation device without using the temperature difference between conventional hot springs and seawater.

発明の実施するための最良の形態BEST MODE FOR CARRYING OUT THE INVENTION

以下、本発明の実施の形態を図１に基づいて説明する。Hereinafter, an embodiment of the present invention will be described with reference to FIG.

図１は、太陽光を利用して、水（その他の媒体）の温度を上昇させて、その温度が上昇した媒体を低沸点媒体が充填された、容器に熱交換器を通して、低沸点媒体の温度を上昇させ蒸気を発生させ、その蒸気で、タービンを回転させ、その回転力で発電機を駆動し、発電を行う。低沸点媒体は、複水器を通して液体へと戻り、再び熱交換器を通して、蒸気を発生させ、同様に発電を繰り返す。FIG. 1 shows the use of sunlight to increase the temperature of water (other medium) and pass the medium having the increased temperature through a heat exchanger into a container filled with a low boiling point medium. The temperature is increased to generate steam, and the turbine is rotated by the steam, and the generator is driven by the rotational force to generate power. The low boiling point medium returns to the liquid through the double water generator, and again generates heat through the heat exchanger and repeats power generation in the same manner.

複水器には、空冷式と水冷式を選択出来る。水冷式の場合、温水を発生させることが出来、蓄湯することで、風呂、冷暖房に利用出来る。For the water doubler, an air cooling type or a water cooling type can be selected. In the case of the water-cooled type, warm water can be generated, and it can be used for bathing and air-conditioning by storing hot water.
