Experimental analysis of a portable atmospheric water generator by thermoelectric cooling method

A portable water generator (7 kg) with two thermoelectric coolers (TECs) was designed and experimentally investigated in this study. Different inlet air relative humidity (RH) and air flow rates were investigated to obtain their impacts on the amount of generated water and condensation rate. The amo...

Description
Summary:A portable water generator (7 kg) with two thermoelectric coolers (TECs) was designed and experimentally investigated in this study. Different inlet air relative humidity (RH) and air flow rates were investigated to obtain their impacts on the amount of generated water and condensation rate. The amount of generated water and condensation rate increased with the RH rose. The amount of generated water increased with air flow rates rose but the condensation rate had opposite trend. The maximum amount of generated water was 25.1 g each hour with 0.216 m2 condensation surface and 58.2 W input power. This system had small size and could work at small air flow rates which was suitable for outdoor use. This study had a guiding role in designing and optimizing a high-efficient portable water generator.
