The rest of the sprayed water is poured on the collector box, which is located beneath the PV panel that works like the solar absorber in the photovoltaic-thermal humidifier. The water flows down along the box, with a counter-current flow relative to the air, and absorbs heat from the box and the hot airflow.
To provide both thermal and electrical energies needed for the humidification-dehumidification (HDH) desalination systems independent of fossil fuels, the present study proposed a photovoltaic-thermal (PVT) solar humidifier.
The solar humidifier designed for the desalination system is a double-pass dual-fluid photovoltaic-thermal collector ( ). It was comprised of the PV panel, as the solar absorber, glass cover, and box channel located beneath the PV panel. The upper surface of the box is warmed in direct contact with the PV panel.
Specific electrical energy consumption values varied from 0.22 to 0.53 kWh/kg. The maximum thermal and electrical efficiencies of the PVT humidifier were 75.6 and 11.3%, respectively. More than 95% of the electrical energy of the system was supplied by the solar humidifier.
In the present work, a solar PVT collector was developed as the humidifier in an HDH desalination system that was equipped with a heat pump. The evaluation experiments were conducted at the different seawater mass flow rates and condensation temperatures. The results revealed that:
