Experimental thermal and electrical performances of a PVT-air collector coupled to a humidification-dehumidification (HDH) cycle

Experimental investigation of a solar desalination performance based on humidification-dehumidification technique with air and water closed cycle

In this study, the performance of solar desalination by humidification-dehumidification of closed air and water in Ahvaz city was investigated. This desalination includes a collector, condenser, salty water, freshwater tanks, air blower, and water pump. The evaluation of the system was done at three levels of air velocity (3, 4, and 5 m/s) and at three pump discharge levels (2, 4, and 6 liters/...

Experimental investigation of thermal and electrical performances of a nanofluid-cooled photovoltaic/thermal system equipped with a sheet-and-grooved serpentine tube collector

Introduction: In the present experimental investigation, the thermal and electrical performances of a photovoltaic/thermal system equipped with a sheet-and-grooved serpentine tube collector are investigated. The water-magnetite nanofluid is used as the heat transfer fluid. The effect of nanoparticle volume concentration (0-1%), nanofluid mass flow rate (10-40 kg/h) and groove pitch (0, 0.54 an...

Evaluation of a PVT Air Collector

Hybrid Photovoltaic Thermal (PVT) collectors are an emerging technology that combines PV and solar thermal systems in a single solar collector producing heat and electricity simultaneously. The focus of this thesis work is to evaluate the performance of unglazed open loop PVT air system integrated on a garage roof in Borlänge. As it is thought to have a significant potential for preheating vent...

Experimental Study of Humidification-Dehumidification (HDH) Seawater Desalination Driven by Solar Energy

Experimental Validation for Two Stages Humidification- Dehumidification (hdh) Water Desalination Unit

This paper demonstrates the preliminary experiments for two stage water desalination by humidification-dehumidification HDH process. An experimental set-up consists of two stages of closed air humidification dehumidification units. In this design, the saline water was heated by evacuated tube solar water heater integrated with electrically heated tank. A series of tests were performed in outdoo...
