Description

technical field [0001] The invention relates to the technical field of purified water preparation, in particular to a device and method for realizing air water intake and seawater desalination based on semiconductor refrigeration. Background technique [0002] As an indispensable and important resource in human society, water resources are an important condition for the existence of life on earth. According to the survey, there are currently 100 countries in the world lacking water, 26 countries are severely lacking in water (including China), and 40% of the population suffers from lack of water. Although my country has a vast territory and ranks fourth in the world in terms of total water resources, my country's per capita freshwater resources rank more than 100 in the world, and it is one of the 26 countries with severe water shortages in the world. At present, the use of conventional water sources such as surface freshwater (rivers and lakes), groundwater and rainwater, ...

Problems solved by technology

In many previous studies, semiconductor refrigeration technology has been widely used in the fields of condensation water intake and condensation in seawater desalination to produce fresh water. Existing research often uses active heat dissipation to deal with the heat generated by the hot end of semiconductor refrigeration. This means that this part of the energy has not been fully utilized, and in the prior art, the evaporation chamber and the condensation chamber need to be connected to achieve condensation water intake, which cannot simultaneously achieve air water intake and seawater desalination
