During the last years, special attention has been paid to renewable polygeneration technologies, able of simultaneously producing thermal, cooling, electrical energy and desalinated water from seawater. This paper focuses on an innovative polygeneration system driven by renewable energy sources, including the following technologies: hybrid photovoltaic/thermal collectors, concentrating paraboli...
This research is proposed to fully investigate the performance of a single-effect water/lithium bromide absorption chiller driven by geothermal energy. Since cycles are considered as low-grade energy cycles, this innovative idea rejecting fluid from single-flash power plant with would serve efficient, economical, and promising technology. In order examine feasibility approach, residential build...
Although water-cooled chillers are more energy efficient than air-cooled chillers, a majority of chilled water systems use air-cooled chillers. In cold weather climates, air-cooled chillers are capable of functioning in low ambient temperatures with few operational concerns, where as water-cooled chiller systems must be equipped to prevent cooling tower freezing. The integrated chiller system a...
Polygeneration of hydrogen, heat, and power has been shown to improve overall plant efficiency by creating more products and introducing synergy which improve fuel cell performance (Figure 1). The integration of an absorption chiller with a high temperature fuel cell for polygeneration of combined cooling, heating, hydrogen, and power is studied. Steady-state and dynamic computer models are uti...
There has been a long history of unexplained anomalous absorption of solar radiation by clouds. Collocated satellite and surface measurements of solar radiation at five geographically diverse locations showed significant solar absorption by clouds, resulting in about 25 watts per square meter more global-mean absorption by the cloudy atmosphere than predicted by theoretical models. It has often...
To detect degradation in energy efficiency of a chiller in a chiller plant, a multivariate Gaussian mixture model is applied. This classification technique was selected to take advantage of an expected correlation between measurable state variables and equipment and operation specifications and system control targets. The hidden variable is the faultiness of the chiller and can take on one of t...
