Solar Water Condensation Using Thermoelectric Coolers

Abstract

Water resources for irrigation can be difficult to obtain specially in the arid regions. However, for high
humidity areas such as places close to the sea water can be condensed from the air.the project is an attempt to providing
drinking water to the people where there is shortage of pure and fresh drinking water so that we can overcome the
problem mentioned above. And the proposed solar powered thermoelectric air conditioning system is based on the
principles of peltier effect to create a finite temperature difference across the condenser and the evaporator of the air
conditioning system. Cold side of the thermoelectric module is used for air conditioning application provides cooling to
the living space. The thermal energy from hot side of module is dumped to the surrounding environment. Consists of
cooling element, heat exchange unit and air circulation unit. A solar cell panel unit with a relevant high current output
drives the cooling elements though a controlling circuit.
