“…Commonly many rooftop areas are not sufficient to install many solar collectors, or many solar collectors can be too expensive. Said et al [16] accomplished a mathematical analysis on a solar cooling system with single effect absorption chiller system, evaluating the global chiller's COP. To verify the reliability of the mathematical model they made up an experimental plant testing it for two days.…”

The amount of energy for air conditioning in the summer time in Mediterranean Area is very high because of hot weather and high temperature values. Solar cooling technology is interesting because strong sunlight covers the cooling requirement. The heat energy from the sun it is available when the demand of electricity has high peaks for the strong use for air conditioning devices. In this work, an analysis by means of NEGST software (New Generation of Solar Thermal System) on a solar cooling and heating system located in the southern part of Italy has been carried out. The building is a Quality Assurance Office of a chemical industry.

Palabras claveCoeficiente de desempeño, energía solar, refrigeración por absorción, simulación. ResumenEl departamento de Córdoba cuenta con zonas rurales que no hacen parte del sistema interconectado nacional. Esto crea un problema para sus habitantes ya que, no pueden conservar alimentos. Sin embargo, la alta disponibilidad de radiación solar durante todo el año, ofrece una alternativa para preservar alimentos utilizando equipos de refrigeración por absorción solar. El objetivo de este trabajo fue simular y analizar un sistema de refrigeración por absorción solar, usando el software ASPEN Hysys. Se obtuvo un coeficiente de desempeño (COP) máximo de 1,0 a 93°C y 1547 kPa, teniendo en cuenta el efecto de distintas variables. Key wordsAbsorption Refrigeration, Coefficient of Performance, Simulation, Solar Energy. AbstractToday, some of the rural areas of Cordoba department are not part of the electrical wiring interconnection system; a problem when it comes to food preservation. Cordoba is subject to high solar radiation throughout the year; therefore, the development of devices powered by an alternative energy source may provide the solution to this problem. The aim of this study was to simulate and analyze an intermittent refrigeration system using ASPEN Hysys software. The simulation was carried out in order to obtain a maximum coefficient of performance (COP) of 1.0 at 93°C and 1547 kPa, considering the effect of variables such as ammonia concentration, amount of solution, pressure generation, and temperature generation. IntroduccIónEl consumo energético global ha presentado un incremento significativo durante los últimos años como resultado del crecimiento acelerado en la población mundial y en la economía, especialmente en los países en desarrollo. De acuerdo con lo anterior, se prevé un incremento del 71 % del consumo energético entre 2003 y 2030 (Sarbu & Adam, 2011).Actualmente, la mayor parte de la energía utilizada en todo el mundo proviene principalmente de combustibles fósiles. Estos combustibles son limitados y se utilizan más rápido de lo que se crean, no son amigables con el medio ambiente y su quema se convierte en el principal contribuyente al calentamiento global. Esto traerá escasez con el tiempo. De ahí que sea necesaria la implementación de fuentes de energía amigables con el medio ambiente y que puedan renovarse

“…This device is used in ethylene separation process, can enhance the technological level of ethylene facilities, save investment, reduce energy consumption, and strengthen the competitiveness of a product [8]. In addition, coefficient of performance (COP) increased by 10% because of the dephlegmator heat recovery, and the evaporator cooling capacity increased [9,10].…”
