The carried out system is modelized and simulated by using the commercial code TRNSYS. Doing this was possible by including a novel component able to simulate the physical behaviour of the DCMD. The simulation of the solar distillation system has been done during the 21st June under the meteorological conditions of Ain Temouchent city (Algeria). The results showed that the present model has a good agreement with the experimental data of the literature. The present desalination system allows getting a daily distillate production around 56 l/d. Furthermore, concerning the performance parameters, it was found that the energy collected, energy delivered by solar coil and to load reach to 953,25 kJ.h−1, 929,43 kJ.h−1 and 7542 kJ.h−1 respectively. The solar fraction ranged from 0 to1 and the collector efficiencies was assessed 36%.

The designed system includes a 2 m 2 flat plate collector (FPC) for thermal energy production, a stratified fluid storage tank with optional internal heater and heat exchangers with 0.3 m 3 of volume, DCMD modules for clean water production, and a PV panel with a maximum power of 55 W. The predicted performance of this system was analyzed and dynamically simulated using the TRNSYS (Transient System Simulation program) code. The DCMD unit was simulated and added to the software library. The DCMD unit and the thermal system were validated based on literature results. The dynamic simulation of this system was carried out in the region of Ain Témouchent (west of Algeria) throughout the year and focusing on 3 type days (24/01), (24/06), and (05/11). The obtained results show that the daily freshwater production by the system is around 59.34 L-1 m 2 d-1 , and that the temperature of the feed saltwater and the permeate flow through the DCMD system varies, respectively, from 60°C to 21°C and between 20°C and 34°C. In addition, the solar fraction (SF) reaches 0.41, 0.52, and 0.42 and the collector efficiency of FPC values reaches 52%, 64%, and 55% during the 3 selected days, respectively.

Currently, among the various desalination processes, the reverse osmosis technique is the most used. Electrical energy consumption is the most attractive factor in the cost of operating seawater by reverse osmosis in desalination plants. Desalination of water by solar energy can be considered as a very important drinking water alternative. For determining the electrical energy consumption of a single reverse osmosis module, we used the System Advisor Model (SAM) to determine the technical characteristics and costs of a parabolic cylindrical installation and Reverse Osmosis System Analysis (ROSA) to obtain the electrical power of a single reverse osmosis module. The electrical power of a single module is ...

In this paper, the integrated single cassette air-gap membrane distillation (AGMD) module in the solar thermal desalination system is validated and numerically simulated with the TRNSYS program. This model is studied to be ideal for obtaining a distilled water flow rate of 5.5 kg/h at different times under changing climatic conditions throughout the year in Ain-Temouchent weather, Algeria. The auxiliary heater is added to ensure the thermal energy continuity in the cold climatic conditions, where the photovoltaic system is used to power electrically the auxiliary heater. Therefore, the energy needed is calculated for the auxiliary heater and is replaced by 10 photovoltaic panels, each one has an area of 1.6 m2 using seven of the energy storage batteries (12V, 200Ah) with 1.5 KW via TRNSYS and PVGIS help programs.

The system consist of trough solar collector (PTC) as well as auxiliary components.. The simulation of the system has been done during the day (01/01) under the meteorological conditions of Ain Temouchent city (Algeria). The model compared the energy performance of the systems: case (1) - Rankine cycle facility with solar field and case (2)- Rankine cycle facility without solar field. The results showed that the present model has a good agreement with the experimental data of the literature. In case (1), PTC fluid outlet temperature reach the maximum value 330 ° C, Work of the steam turbine increase from the 9hr to reach its maximum value 856 KJ/Kg at 13 hr. In case (2), the maximum value of the power remains constant from the beginning of the simulation to 1hr00. Since the flow of fuel (gas natural) consumed does not change throughout the operating period.
