Hybrid potable water generator

A hybrid system for concurrent production of desalinated water from atmospheric moisture and seawater, comprising:

• a solar photovoltaic cell connected to a battery which provides electrical power to a compressor and a fan, wherein the compressor is fluidly connected to first, second and third heat exchangers;
• wherein the fan is configured to direct a flow of atmospheric air through the second heat exchanger, said air conveyed to an atmospheric water collector,
• a saline water evaporation chamber configured so that the flow of the atmospheric air after passing through the second heat exchanger cools an outer surface of the roof of the saline water evaporation chamber and is configured to condense water vapor on a cooled roof of the saline water evaporation chamber,
• wherein the saline water evaporation chamber contains the first heat exchanger downstream of the compressor and is configured to cool a compressed and hot refrigerant in the first heat-exchanger by passing thermal energy from the compressed and hot refrigerant to saline water present in the saline water evaporation chamber;
• an expansion device downstream of the first heat exchanger to adiabatically expand and cool the refrigerant and pass an expanded and cooled refrigerant through a first exit and a second exit,
• wherein the expanded and cooled refrigerant from the first exit passes through the second heat exchanger which is in contact with the flow of atmospheric air to condense water vapor from the atmospheric air in the unit,
• wherein the expanded and cooled refrigerant from the second exit passes through the third heat exchanger which is in thermal connection with the solar photovoltaic cell and is configured as a heat sink to the solar photovoltaic cell,
• wherein the gaseous refrigerant from the second heat exchanger and the solar photovoltaic cell combine downstream of the second and third heat exchangers into a single gaseous refrigerant feed line to the compressor;
• wherein dehumidified cooled air after leaving the atmospheric water collector is flown tangentially to a surface of a water vapor barrier film covering the saline evaporation chamber, wherein the tangential flow is provided by installing a rigid sheath in parallel to said water vapor barrier limiting the saline evaporation chamber, wherein the cool dehumidified airflow is in a turbulent regime in the flat space between the water vapor barrier films, wherein the distance between the films is from 1 to 10 cm;
• and
• wherein the fan-driven flow of the dehumidified air attracts a portion of ambient air also acting as a coolant for the evaporation chamber roof.
