Solar energy photovoltaic direct current air water fetching device

Abstract

The present invention relates to a solar photovoltaic direct current air water intake device. The present invention comprises a solar power supply system, a box body assembly and a battery, and the box body assembly comprises a refrigeration system, an air water intake apparatus and a box body, the solar power supply system is respectively connected with the battery and the direct current compressor of a refrigeration system through a controller, the refrigeration system and the air water intake apparatus are arranged in the box body, and a master switch is arranged on the outer wall of the box body. When the solar radiation is sufficient, a solar battery board converts the received sunlight radiant energy into direct current power for outputting, and the direct current compressor drives the refrigeration system to operate, and the redundant power is stored to the battery; when the solar radiation intensity is not strong or in the rainy weather, the direct current power converted by the solar battery board is less than the consumption of the system, and the power in the battery is released for maintaining the normal system operation. The present invention applies the photovoltaic direct current compression refrigeration technology to the air water intake system, thereby, the refrigeration coefficient is high, the water intake rate is high, the continuous operation time is long without sunshine, and the present invention can be applied in the areas lacking of water and electricity but sufficient in sunshine.

Description

technical field [0001] The invention relates to a solar photovoltaic DC air water intake device, which is an air water intake device driven by solar energy as a power source. Background technique [0002] With the rapid growth of the global population, human demand for fresh water has also increased sharply, and the originally not very rich fresh water resources have become even more scarce under the double blow of environmental pollution and irrational use. However, ensuring the supply of fresh water is precisely the prerequisite for all human activities. With the progress of society and the development of science and technology, human activities are becoming more and more frequent in places where fresh water resources are scarce (such as deserts). These activities are inseparable from the supply of fresh water. Therefore, how to effectively obtain fresh water in places where fresh water is scarce , has become a difficult problem that human beings worry about and urgently ...

Problems solved by technology

Although this technology has the advantages of small size, light weight, and easy portability compared to adsorption refrigeration and vapor compression refrigeration, it has low refrigeration efficiency, poor water intake effect, and does not have the ability to operate continuously without sunlight.
