Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desalination apparatus for cooling a desalination panel to an appropriate temperature and condensing water vapor in the atmosphere into water by the condensation principle to produce water.

[0002]

2. Description of the Related Art Conventionally, various desalination technologies and devices have been researched and developed to improve living standards, increase demand for water such as industrial water, and to prevent drought due to lack of rain. A typical example is a seawater desalination apparatus, and in particular, an evaporation method has been known for a long time, and recently, an electrodialysis method and a reverse osmosis method have been performed. Also, in recent years, various water producing devices have been invented focusing on water vapor in the atmosphere. The main method is to attach water vapor to a hygroscopic substance (such as silica gel) and then evaporate it again. As a method for obtaining water by further cooling, Patent Publications Sho 57-4211, Sho 58-17719, Sho 61-1
7805, Sho 63-1418, etc. are listed. As another method of producing water, the method of collecting water adhering to the fins during cooling by utilizing the principle of drainage discharged from the refrigeration cycle to produce water is disclosed in Japanese Patent Publication Nos. 57-38929 and 60-.
132690, flat 3-144272, flat 4-25023

[Problems to be Solved by the Invention] However, when obtaining water by the seawater desalination method, a problem in any method is to use seawater as raw water, and the seawater to be raw water is an average. The salt concentration is as high as 3.4%, there are many impurities, and scales are generated. Therefore, pretreatment is always required, and the equipment cost is high due to the corrosion problem of the plant due to salt content and durability measures. Moreover, maintenance frequency is high in any method, and energy costs for water production are also problems. There was also. Next, in any of the methods of converting water vapor in the atmosphere into water, the equipment cost is high because the desalination process is complicated, and the energy cost for the desalination is extremely bad. Compared to the desalination method, it was not practical. For this reason, there has been a demand for a technology that is cheaper than before, does not require pretreatment, does not worry about corrosion, requires less maintenance, and can produce water at low cost.
It didn't happen yet.

8 and the cooling unit 5 are provided. (B) The temperature sensor 9 is provided inside the fresh water panel 1, the external temperature / humidity sensor 11 for the atmosphere is provided, and the cooling unit 5 and the pumps 6 and 8 are arbitrarily controlled by the microcomputer unit 4 connected to each sensor. Then, a coolant cooled to an appropriate temperature is circulated in each fresh water panel 1 to create the fresh water panel 1
The surface is always kept at the dew point, and water vapor in the atmosphere is condensed (condensation) to obtain water. A refrigerator fresh water generator configured as described above.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described. The device of the present invention has the above-mentioned configuration, and when the water is required to make water due to drought or the like, the temperature and humidity in the atmosphere are detected by the external temperature / humidity sensor 11, and the microcomputer unit 4 and the cooling unit 5 detect the information. And the pumps 6 and 8 are operated to cool the refrigerant to an appropriate temperature, and each fresh water panel 1
By circulating the inside and always making the surface of the fresh water panel 1 the dew point, water vapor in the atmosphere is condensed (condensed) to make water.

[0006]

[Embodiment] By providing the solar cell panel 2 on the front surface of the south side of the fresh water panel 1 on the side of the sun's rays, the energy cost at the time of fresh water is reduced by the electric power obtained thereby. Further, when it is necessary to make water in low temperatures such as in the winter and cold regions, it is possible to make water by switching the cooling unit 5 to a heater and heating. As the coolant material, a mixture of a liquid such as water, freon, gel, or water with a polymer absorber can be used. The water-making panel 1 is made of a resin material such as acrylic resin, so that the device cost is lower than that of metal, and there is no fear of corrosion. Furthermore, the fresh water panel 1 has a black color to promote heat exchange and further reduce the condensation time of water vapor. Moreover, when the refrigerant is water, moss is generated. Can also be prevented. Furthermore, the larger the area of the fresh water panel 1 and the larger the number, the more fresh water can be created.
It is also clear from the fact that the atmospheric area and water vapor are proportional. In addition, when installing the device of the present invention,
It can be installed directly on the dam lake, on an intermediate river to the water purification plant, on the water purification pond of the water purification plant, etc. In that case, the fresh water panel 1 can be fixed by a frame or the like.

[0007]

Therefore, the device of the present invention can be installed inland as a measure against the increase in demand for domestic water, industrial water, etc., especially in the case of measures against drought, because raw water such as seawater is not required. In addition, there is no need for pretreatment, and the water production process is simple, so the equipment cost is low, there is no concern about corrosion, maintenance frequency is extremely low, and the water production cost is reduced by the electricity from the solar cell panel. It is further reduced, and the operation of the microcomputer unit enables 24-hour unattended operation. In addition, the device of the present invention is configured so that the water produced by the device is always purified by the water purification plant before use. Therefore, the water produced by the device is directly used as drinking water. In this case, the equipment is stored, filters, etc. are used to prevent contamination of dust and dirt, and the produced water is sterilized by ozone, etc., and minerals are added because it is close to pure water. It can be used as drinking water.
