Atmospheric water generator apparatus

An apparatus, which comprises:

• a fluid heating device;
• a fluid cooling device, wherein said fluid cooling device comprises a throttle;
• means to enhance water condensation from ambient air on a water condensing surface, said water condensing surface thermally connected to said fluid cooling device, said water condensing surface includes a plurality of protruding fin-like surfaces protruding from a tube, said water condensing surface comprising a superhydrophobic coating on the water condensing surface, a superhydrophilic coating on the water condensing surface, or a combination thereof;
• an air-cooled heat rejection device in fluid communication with said fluid heating device;
• and
• an air fan configured to induce airflow across said water condensing surface.
