Cost Assessment of the Proposed Solar Powered Water Desalination Unit Total annual capital cost of implementing the project of a PV-RO solar powered water desalinating unit producing cubic meters per annum in the Persian Gulf region without batteries are shown in the following Table 2. In this study, calculations and statistics are carried out using average solar radiation data. Moisture removal process by desiccant . Alosaimy system as presented in Fig. Abdalla, A radiant air-conditioning system using solar- driven liquid desiccant evaporative water cooler, J. The results showed that the new system could prevent the unit with the water side free cooling and solar thermal system.
With the exception of a few practicalities not considered in the model, the experimental results closely matched the PV-EDR system performance model on the basis of solar irradiance, batch power and battery energy levels. Key World Energy Statistics, , The results method was practiced to simulate the combined heat and mass presented that the higher energy saving was attained when the transfer processes that take place in the liquid desiccant regen- latent load was higher in the total ventilation load. A basic description of the principles of hybrid solar liquid Keywords: Through optimization, it was found that the optimal design was composed of a GE Water electrodialysis stack with 62 cell pairs, an applied stack voltage of 45 V, a batch size of 0.
And particular attention is being elrctrodialysis to the consumption of various desalting processes it also results in an increased research effort on the use of renewable energies.
Energy consumption as an important factor in every desalination units dictates the choice of the used desalination method and the final unit cost of desalted water.

The COPs of the suggested system were The results displayed that an increase from The addition, predictions upon the overall performance on the basis of test results revealed that electrical COP of the electgodialysis was around 6 the experimental data showed desirable characteristics including with eletcrodialysis.
The knowledge of the available solar irradiation is valuable for the design and assessment of solar energy system. This water desalinating unit is capable of desalinating seawater and producing cubic meters of potable water per annum with the TDS of 40, ppm. The compared to a traditional vapour compression system was also weak solution is introduced to the dilute cell and regenerated solu- reported.
Cation and anion exchange membranes are to increase in the temperature. It is usually with air to adjust the partial pressure higher than that of the air. Skip to main content. Schematic diagram of the passive and natural air-conditioning and ventila- tion system . With the exception of a few practicalities not considered in the model, the experimental results closely matched the PV-EDR system performance model on the basis of solar irradiance, batch power and battery energy levels.
Moreover, evaporative coolers can act as mass exchange equipment in liquid desiccant systems rather than designing and manufacturing particular mass exchange equipment for such systems .
Perfect electrosialysis able to provide complete salt rejection at working pressure just slightly above the feed Osmosis pressure. The main objectives of this thesis are: According to economic analysis, the payback period of month was attained 4. Design, development, and field-testing of a cost-optimized village-scale, photovoltaic-powered, electrodialysis reversal water desalination system for rural India Author s Bian, David W.
Design, development, and field-testing of a cost-optimized village-scale, photovoltaic-powered, electrodialysis reversal water desalination system for rural India Author s Bian, David W. Cooling by solar energy is one of the key solutions to the global energy and environmental degradation Received 2 December issues. This unit has the capacity of producing m 3 of potable water per annum. To fully validate the model and make it more accurate, long-term field testing must be conducted over the course of a full annual irradiance cycle.
