Modeling multi effect distillation powered by CSP in TRNSYS

This work presents the results of using a new tool to simulate the cogeneration of water and electricity with Concentrating Solar Power (CSP) and Forward Feed Multi-Effect-Desalination (FF-MED) plants, by adding a new functionality to the System Advisor Model (SAM) developed by the US National Renewable Energy Laboratory (NREL). The controlling strategy of the MED model is presented in detail, and a case study ...

Optimization of a seasonal storage solar system using Genetic Algorithms

Seasonal storage solar systems are capable of storing thermal energy, from one season to another (typically a few months). In the present paper solar thermal energy generated during summer time, is stored for use in winter time (typically 120 days). The analyzed system consists of solar thermal collectors and a sensible heat storage device using water as storing media. The area of solar collector and the capaci...

Components of solar thermal systems

The heat production sub-system is the part of the overall system which provides heat to a thermally driven air-conditioning system. With regards to the solar-driven equipment, the solar collector is the main component of the sub-system. A brief review on the present state-of-the-art with respect to performance characteristics and available certification schemes of solar collectors is given in the following chap...

Experimental validation of MED forward feed steady-state model

In this work the validation of a physical model to simulate the performance of an MED forward feed system is done by comparing results of the model with real data obtained. The data was obtained using the experimental MED plant at Plataforma Solar de Almeria (PSA) under steady-state operation near design conditions. The results indicate that the model can be used to make a first analysis on these type of systems. 

Water content control to improve space charge storage in a cork derivative

The influence of humidity content on the electrical and dielectric properties of a composite made from recycled TetraPak® containers and granulated cork was studied. The material components have been dried before preparation and after the composite was conditioned by keeping the samples in a dry environment (desiccator) or in an oven at high temperature (70oC in air). The differences observed in electrical prop...

Sistemas de concentração solar em aplicações agro industriais

As tecnologias de concentração solar podem ser utilizadas na produção de electricidade ou na produção dos chamados combustíveis solares, através da concentração óptica da radiação solar que permite a obtenção das elevadas temperaturas necessárias a esses processos. São as Centrais Termo-Solares (CSP) que oferecem uma grande flexibilidade pois a energia térmica produzida pode ser armazenada em tanques, para prod...
