Description

Integrated system for water, refrigeration and air purification

Technical field

The invention belongs to the technical field of water machine, and relates to an air water system, in particular to an air water, refrigeration and air purification integrated system.

Background technique

Water is an indispensable resource for human survival. The problem of drinking water has gradually become a serious problem facing humanity in recent years. Studies have shown that 72% of the Earth's surface is covered by water, with a water storage capacity of 1.45 billion cubic kilometers, but freshwater resources account for only 0.75% of all water resources, and 70% of this freshwater resource alone. It is distributed in the ice layer left and right, and the rest is mostly soil water or deep groundwater, which is difficult to be used by humans. With the development of urban industry, urban water sources are seriously polluted by industry. A little bit of water pipelines will also cause algae breeding, which seriously affects water quality and causes secondary pollution in transportation.

How to make full use of water resources and obtain safer drinking water. At present, countries and research institutes all over the world have carried out related research, such as mist water intake system, morning dew collection system, water intake by salt solution, use of air and subsurface temperature condensation. The formation of water and refrigeration condensation, etc., the principle of refrigeration condensation is basically the same as the principle of air conditioning steam compressor, the air is filtered and flows through the surface of the evaporator (the evaporator surface temperature is lower than the air saturation dew point temperature) and then condenses into water droplets. It can be made into drinking water after collection. At present, air water has been gradually developed. Because the water on the ground evaporates into the air, the air also contains a certain amount of water, especially in many southern regions. The rainfall is abundant, the air humidity is large, and the air contains a lot of water. Making full use of these waters will greatly alleviate the lack of drinking water in various disaster areas, in the wild, in remote areas, and in areas with scarce fresh water resources. It can directly break the regional restrictions, and water can be produced as long as there is air. However, air-based water machines on the market can only be used to take water from the air.
