Description

Technical field [0001] The invention relates to seawater desalination technology, in particular to a solar photovoltaic semiconductor refrigeration type seawater desalination device. Background technique [0002] Desalination has actually become a key technology for many countries in the world to solve the problem of water shortage, and it is also a commonly used strategic choice. Its reliability and effectiveness have been widely recognized. [0003] Desalination is the use of seawater desalination to produce fresh water. It is an open source incremental technology to realize the utilization of water resources. It can increase the total amount of fresh water and is not affected by time, space and climate. Because solar energy is environmentally friendly, pollution-free, and inexhaustible, solar energy is currently used for desalination. However, solar energy has a low energy density and is unstable due to time and weather. At the same time, the existing solar water desalination ...
