Air-Heating Solar Collectors for Humidification-Dehumidification Desalination Systems
Relative to solar water heaters, solar air heaters have received relatively little investigation and have resulted in few commercial products. However, in the context of a humidification-dehumidification (HDH) desalination cycle, air heating accounts for advantages in cycle performance. Solar collectors can be over 40% of an air-heated HDH system’s cost; thus, design optimization is crucial. Be...
متن کاملExergy Analysis of a Solar Humidification- Dehumidification Desalination Unit
This paper presents the exergy analysis of a desalination unit using humidification-dehumidification process. Here, this unit is considered as a thermal system with three main components, which are the heating unit by using a solar collector, the evaporator or the humidifier, and the condenser or the dehumidifier. In these components the exergy is a measure of the quality or grade of energy and...
متن کاملThermodynamic Analysis of Humidification Dehumidification Desalination Cycles
Humidification dehumidification desalination (HDH) is a promising technology for small-scale water production applications. There are several embodiments of this technology which have been investigated by researchers around the world. However, from a previous literature review [1], we have found no study which carried out a detailed thermodynamic analysis in order to improve and/or optimize the...
متن کاملVariable Pressure Humidification Dehumidification Desalination System
Nature uses air as a carrier gas to desalinate seawater through evaporation and rain. Several investigators have previously studied desalination cycles based on carrier gas processes. However, single pressure carrier gas cycles suffer from low energy recovery and hence low performance. Here we discuss a novel carrier gas cycle which operates under varied pressure. This cycle operates the evapor...
متن کاملExperimental 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/...
