In order to understand the behavior and to determine the effective operational parameters of a solar-driven ejector air conditioning system at low or medium temperature, a dynamic model depends on the principles of conservation, the momentum mass and energy is developed. For this purpose, the thermodynamic characteristics of the liquid and vapor refrigerant were identified using the Engineering Equation Solver (EES) software. Linear Fresnel solar reflector has been used as a tool to convert solar energy into thermal energy. Water (R718) was used as a refrigerant. The operational conditions for the studied solar-driven ejector air conditioning system are as follows: evaporator temperature "T e =283.15 K", condenser temperature "T c =305.15 K", and generator temperature "T g = 373.15 K". The performance of the ejector air conditioning system was compared as a function of the operating parameters of the subsystem. The average value of thermal efficiency of the Fresnel linear concentrator has reached 31.60 %, the drive ratio "ω" is 0.4934, the performance value of the ejector air conditioning subsystem "COPejc" is 60.664 % and the average value of the thermal performance of the machine "STR" has touched 19.17 %. The results obtained through this scientific subject are stimulating and encouraging, where this technique can be used for air conditioning in desert areas in southern Algeria, where fossil energy (petroleum, gas, etc.) is extracted and produced in various types.

“…La sucesiva llegada de población del resto del país propició aglomeraciones urbanas antes desconocidas y que a lo largo de las últimas décadas se han consolidado en ciudades intermedias (Wilson y Bayón, 2017). En las últimas décadas la región ha vivido una nueva oleada de proyectos extractivos mineros (abriéndose en la región sur el ciclo megaminero con la consolidación del primer proyecto de cobre y oro), petroleros (con una década intensiva de apertura de nuevos pozos petroleros en la región norte) e infraestructurales (con la consolidación de una nueva red de carreteras que ha recibido una inversión sin precedentes) (Bayón, 2019). En la actualidad, este devenir ha generado un proceso dual de urbanización, con ciudades intermedias con el crecimiento poblacional más explosivo del país, y una retícula de numerosos núcleos emergentes alrededor de las carreteras, en la actualidad protagonizado por las migraciones intra-amazónicas (INEC, 2010;Cabrera et al, 2020).…”

como uno de los abordajes principales dentro del debate sobre los extractivismos en Ecuador. Desde nuestra contribución activa a este debate, nuestro objetivo con este artículo es reflexionar sobre los aportes y limitaciones que ha supuesto la ecología política latinoamericana para el análisis del extractivismo, y en particular las posiciones de los sujetos comunitarios e indígenas. Analizaremos el enfoque analítico que se da a escenarios de conflicto, y cómo este tiende a asignar a dichos sujetos un lugar fijo tanto geográfico como de enunciación. Esto pueda representar un limitante, particularmente en casos donde la construcción del espacio, la naturaleza, y las posiciones de los sujetos se atraviesa por historias y prácticas de movilidad. Con base en tres estudios de casos de despojo extractivo-capitalista en la Amazonía Ecuatoriana, mostramos que al establecer un diálogo entre la ecología política y la geografía crítica de las movilidades se puede enriquecer el enfoque analítico sobre el extractivismo y las posiciones de los sujetos.Palabras clave: (in)movilidades, urbanización indígena, geografía crítica.

A Review of Daylighting System: For Prototype Systems Performance and Development

et al. 2019

Daylighting systems make daylight illuminance possible, and the development of prototype daylighting systems can provide more efficient daylight illuminance. The purpose of this article is to review the development and performance of prototype daylighting systems in the last decade. The passive and active daylighting systems are listed separately and divided into the four categories by the presence and absence of hybrid. Each prototype daylighting system was evaluated in terms of cost and daylight performance and as well as their novel optical design. We evaluated the architecture and daylighting principles of each system by reviewing individual prototype daylighting systems. The cost of prototype systems still poses a challenge to development. How to use passive or active systems in different environments and whether or not electrical lighting assistance is needed is a controversial issue. However, active daylighting systems equipped with solar tracking systems are still mainstream. This research is a valuable resource for daylight researchers and newcomers. It is helpful to understand the advantages of various prototype daylighting systems and commercial daylighting systems that have been developed for many years; moreover, it is also possible to know the research directions suggested by the prototype daylighting systems. These will be of further use in developing innovative and better daylighting systems and designs.
