This article deals with the application of the genetic algorithm (GA) for optimizing an inverse problem and retrieving unknown parameters in cylindrical fin geometry. Parameters such as the thermal conductivity and the heat transfer coefficient are attempted for estimation in order to satisfy a desired temperature field in the medium. The study is done for single-parameter and simultaneous two-parameter retrievals. The temperature field is calculated from a forward problem using the finite difference method using some known values of the properties. These properties are ultimately retrieved by an inverse approach using the GA. The study is done for different controlling parameters such as the number of generations, measurement errors and number of measurement locations. For two parameter simultaneous estimation, many combination of unknown parameters are observed to satisfy a given temperature field, and their ratio is only found to be successfully estimated. The present work is proposed to be useful for selecting the thermal properties which are required to satisfy a given temperature field. (c) 2012 Elsevier B.V. All rights reserved.

Evaluation of the Effectiveness of Base Insulation on the Productivity of a Packed Bed Solar Air Heater

Sunirmit Verma, Ranjan Das

Summary: The effect of bottom surface thermal energy loss on a packed bed solar air heater is investigated using both numerical and analytical models. The study shows that the insulation thickness of the base has a significant impact on the system's output. A collector with no insulation on the base loses a large portion of the incident solar energy, while a thicker insulation reduces the loss fraction. The efficiency of the insulation decreases with larger collector size but increases with a higher mass flow rate of air. This research provides a mathematical tool to calculate the appropriate insulation thermal resistance for packed bed solar air heaters, optimizing thermal performance and minimizing insulation cost.

Performance Analysis of Evaporation and Heat Wheel-Based Building Air Conditioning Systems

Gaurav Singh, Ranjan Das

Summary: Air conditioning in composite weather presents challenges and importance resembling various climate conditions. The separation of cooling and ventilation tasks through a dedicated outdoor air system (DOAS) is an attractive technique for designing energy-efficient air-conditioning systems. This study analyzes the electrical energy consumption of a building's air-conditioning unit when modifications are made to the desiccant-integrated DOAS's air pathway. Simulation results demonstrate that using a heat wheel instead of an indirect evaporation cooler (IEC) can save approximately 2994 kWh of thermal energy with a 5.04% reduction in electrical energy consumption. The suggested design also provides a higher solar fraction.

Sunirmit Verma, Ranjan Das

Summary: This study models a solar pond where thermal energy is extracted from three zones: non-convective zone (NCZ), lower convective zone (LCZ), and the ground below.

The study also evaluates the practical utility of the pond in a desalination application, calculating annual distillate production and studying its variation with adjustable parameters.

Summary: This paper numerically investigates split hemispherical fins mounted staggered over a base plate. The results show that compared to cylindrical fins, hemispherical fins have higher Nu values and ΔP values. The HTPF values of hemispherical fins are greater than unity for all considered Reynolds numbers. Additionally, the hemispherical fins are split into longitudinal and transverse flow directions for better solid-fluid interaction. Finally, the optimum Nu value is obtained using the cuckoo search algorithm and response surface method, with a promising result and a small error.

Performance analysis of a waste heat exchanger with thick separating wall working as a storage medium for continuous operation

Sunirmit Verma, Chetan Aggarwal, Ranjan Das

Summary: In this study, a waste heat exchanger with a thick separating wall is proposed to store waste heat energy and use it when waste heat is not available. The effects of various user-controlled parameters on the system performance have been investigated. It is observed that increasing the exchanger length, width, thicknesses of the separating wall and cold fluid flow passage reduce the outlet cold fluid temperature during the time waste heat is available, while the opposite effect is exhibited when waste heat is unavailable.

Improved energy management of chiller system with AI-based regression

Fu-Wing Yu, Wai-Tung Ho, Chak-Fung Jeff Wong

Summary: This research aims to enhance the energy management in commercial building air-conditioning systems, specifically focusing on chillers. Ridge regression is found to outperform lasso and elastic net regression when optimized with the appropriate hyperparameter, making it the most suitable method for modeling the system coefficient of performance (SCOP). The key variables that strongly influence SCOP include part load ratios, the operating numbers of chillers and pumps, and the temperatures of chilled water and condenser water. Additionally, July is identified as the month with the highest potential for performance improvement. This study introduces a novel approach that balances feature selection, model accuracy, and optimal tuning of hyperparameters, highlighting the significance of a generic and simplified chiller system model in evaluating energy management opportunities for sustainable operation. The findings from this research can guide future efforts towards more energy-efficient and sustainable operations in commercial buildings.

Gerardo Humberto Valencia-Rivera, Maria Torcoroma Benavides-Robles, Alonso Vela Morales, Ivan Amaya, Jorge M. Cruz-Duarte, Jose Carlos Ortiz-Bayliss, Juan Gabriel Avina-Cervantes

Summary: Electric power system applications are complex optimization problems. Most literature reviews focus on studying electrical paradigms using different optimization techniques, but there is a lack of review on Metaheuristics (MHs) in these applications. Our work provides an overview of the paradigms underlying such applications and analyzes the most commonly used MHs and their search operators. We also discover a strong synergy between the Renewable Energies paradigm and other paradigms, and a significant interest in Load-Forecasting optimization problems. Based on our findings, we provide helpful recommendations for current challenges and potential research paths to support further development in this field.
