Problems solved by technology

Some domestic air water generators on the market use mains power supply, which has the disadvantages of high energy consumption and low water production efficiency
Moreover, conventionally designed water generators do not have the ability to resist harsh natural conditions such as salt spray, humidity, and typhoons on islands and reefs, and cannot be directly transplanted to the environmental conditions of islands and reefs.
[0004] Chinese patent CN202021111180 proposes a photovoltaic-powered air-based water production system, which uses a battery-powered DC water generator to obtain fresh water. Since most small and medium-capacity refrigeration compressors are driven by AC, the matching valves and fans are

Abstract

The invention discloses an island reef photovoltaic water production system. The island reef photovoltaic water production system comprises a photovoltaic panel, a photovoltaic inverter, an energy storage battery, a water production machine, a fan, a water tank, a dew point measuring instrument and a temperature and humidity sensor, wherein the photovoltaic inverter is used for charging the energy storage battery and converting the voltage of the energy storage battery into alternating current power frequency electricity to supply power to a refrigeration compressor and the fan; an air outlet of the fan faces a condenser; the photovoltaic inverter is connected with the temperature and humidity sensor, the photovoltaic inverter controls the refrigeration compressor to produce water when the temperature dew point difference is smaller than or equal to 10 DEG C, and the rotating speed of the fan is controlled according to the ratio obtained by dividing the temperature dew point difference by the current relative humidity. According to the island reef photovoltaic water production system, the photovoltaic inverter outputs alternating-current power frequency voltage to drive the refrigeration compressor to work, and higher efficiency and lower cost are achieved; according to the temperature and humidity sensor, starting of water production is determined, the rotating speed of the fan is determined, and the water production machine can produce the water at the highest efficiency all the time.

Description

technical field [0001] The invention belongs to the field of water generators, and more specifically relates to an island and reef photovoltaic water generation system and a water generation method thereof. Background technique [0002] In the island and reef environment, the conventional ways to obtain fresh water include rainwater collection and seawater desalination. Rainwater collection depends on meteorological conditions, while seawater desalination devices have high energy consumption and large volume and weight. They are suitable for islands with large areas and large populations. For small-area Islands and reefs have the disadvantages of difficult operation, complicated maintenance, and difficult infrastructure guarantee. [0003] The air humidity in the island and reef environment is high. It is a better idea to use refrigeration compressors to condense fresh water from the air. Some domestic air-based water generators on the market are powered by mains electricit...
