This paper presents a modeling and optimization investigation of a solar driven adsorption cooling system working with activated carbon–methanol pair. It deals with the effect of internal fins on the thermal behavior of the adsorber and on the system performance. A two-dimensional model...

This study is concerned with the results of a Life Cycle Assessment comparison between photovoltaic – silicon based modules and thin film modules – and solar thermal systems, as technologies which are usually installed for partially covering household energy demand.

The basic SAR (solar-driven adsorption refrigeration) machine is an intermittent cold production system. Recently, the CO-SAR (continuous operation solar-powered adsorption refrigeration) system is developed. The CO-SAR machine is based on the theoretical CTAR (constant temperature adsorption...

This paper reports the experimental results of a single effect absorption cooling system of 3 kW of nominal cooling capacity operating with ammonia–lithium nitrate solution. The system was designed and built in the Instituto de Energías Renovables of the Universidad Nacional Autónoma de...

Hydrogen is a kind of green fuel, and is considered as the substitute oil fuel for future. Although many of literature of photocatalyst water splitting have been presented, little of the literature focused on their energy conversions. Therefore, investigation of their energy conversions is...

The aim of this work is to analyse whether the integration of Multi-Effect Distillation (MED) process into Concentrating Solar Power (CSP) plants can be more competitive, under certain conditions, than the independent freshwater and power production by connecting a Reverse Osmosis (RO) system to...

In a globalized market, part of the goods/services consumed in a country might be produced abroad using diverse energy sources. To properly assess the extent to which a country is moving towards more sustainable energy sources, it is imperative to consider both, the amount of renewable energy...

This article suggests a detailed comparison of 7 working pairs intended for use in solar adsorption cooling systems. The performance analysis was based on two indicators: adsorption capacity and solar coefficient of performance. Based on a reformed form of the Dubinin–Astakhov equation, a 3D...

Energy security is sometimes used to advocate renewable energy systems. Renewable energy systems can improve some aspects of security, but they will not automatically lead to the removal of all types of security problems and new problems will most certainly arise. This paper analyses energy...
