This study focuses on water recuperation from ambiant air moisture using renewable energies.

One in five people in the world has no access to water ... The number of available constant natural resources of water is constantly decreasing ... Hundreds of isolated places in the world are not linked to a water supply network and a huge part of population has no access to water ...

Several existing methods of water recuperation exist but they are expensive and technically complicated to install. For example, notably : Digging a well to access infiltrated groundwater, sea water desalination and ambiant air moisture recovery.

To make this, we create a flow of air which passes across a condensation room. The wall of this condensation room have to be brung to a low temperature to cool the air and allow the condensation phenomenon. Air limit conditions to allow the system to produce liquid water : Temperature: from 18C to 40C; Humidity rate: 45% to 95%.

A theoretical analysis, backed up by real experimentations of condensation, indicates that some physical parameters has to be respected to allow a sufficient liquid water supplying and dew point gap conditions has to be simulated to improve the thermic transfer between the two fluids (air and refrigerant).
