In this study, the electrical and thermal efficiency of natural convection water-cooled photovoltaic panel (PV) is compared with standard PV module. modules are made up polycrystalline solar cells. As it known that, an increase in temperature results a decrease efficiency. The aim study to characteristic values such as air/PV temperature, radiation, voltage, current, power recorded for both pan...

Based on the model-free adaptive control (MFAC) theory, temperature tracking problem of single-effect LiBr/H2O absorption chiller is explored. Due to complex nonlinearity and strong coupling characteristics refrigeration system, strategy designed for its control. Nevertheless, traditional has a slow speed poor denoising ability. In order improve effect, output error rate added objective functio...

Adsorption refrigeration, as a renewable cooling method, has received more attention in the last few years. The interest this technology comes especially from developing and tropical countries, where demand for increases every year due to economy population growth. Based on scenario, work aims develop numerical model of an adsorption chiller driven with solar energy, which can be used optimize ...

In the proposed work, MATLAB program was used to model and simulate performance of investigated two-stage adsorption chiller with without heat recovery using an activated carbon/methanol pair. The simulated results were then validated by experimental conducted Millennium Industries. based on 10th order differential equations; six them predict bed, evaporator condenser temperatures while other f...
