Abstract: Combine solar adsorption air water intake and semiconductor refrigeration technology to design a more efficient and energy-saving air catchment device. The temperature and humidity sensor is added to the system, and the water in the water collection tank is used to cool the hot end of the water cycle by controlling the current of the sensor and the liquid cooling system. Laser sterilization and filtration are applied to the system; solar panels and wind generators are used to provide elec-trical energy for the entire system, to achieve energy-saving and environmental protection, and to collect clean, sanitary and direct drinking water.

${Q}_{C}=\left({a}_{P}-{a}_{N}\right)I{T}_{C}+k\left({T}_{C}-{T}_{B}\right)-\frac{1}{2}{I}^{2}R$ (1)

$W={I}^{2}R+\left({\alpha }_{P}+{\alpha }_{N}\right)\left({T}_{n}-{T}_{c}\right)$ (2)

$\epsilon =\frac{\left({a}_{P}-{a}_{N}\right)I{T}_{C}+k\left({T}_{C}-{T}_{B}\right)-\frac{1}{2}{I}^{2}R}{{a}_{P}+{I}^{2}R-{a}_{N}\left({T}_{n}-{T}_{C}\right)I}$ (3)

$I=\frac{\alpha }{R}\frac{{T}_{C}^{2}\left({T}_{k}-\frac{1}{2}\Delta T\right)+\frac{\Delta {T}^{2}}{Z}}{{T}_{C}\left({T}_{k}+{T}_{C}\right)-\frac{2\Delta T}{Z}}$ (4)
