“…It was clear from research that adding a high thermal conductivity porous layer on a flat plate increases the heat transfer from the plate [38]. As TEG performance is negatively affected by the heat transfer to the sink [39,40] researchers should seek methods of enhancing heat transfer. enhanced micro-energy harvester to transform ambient thermal fluctuations into electricity has been performed [41].…”

“…Several experimental and theoretical studies [13][14][15][16] examined heat transfer from the TEG surface in order to improve its performance and its power generation. TEG with heat pipe heat sink has been investigated with variable fin space, fin length, fin height, fin materials for both natural and forced convection to enhance the TEG performance [17,18]. For the importance of heat transfer the impact of a squared shape fin perforation was tested to increase heat transfer from fins [19][20][21].…”

“…Optimization process is a process of maximizing or minimizing the specified objective. Several methods can be used for multi-objective optimization, namely the Response Surface Methodology (RSM), Multi-objective Optimization using Genetic Algorithm (MOGA), Artificial Neural Network (ANN), and others [8]. Sanaye and Modarrespoor (2014) conducted research related to multi-objective optimization of HPHE for energy recovery in HPHE applications using Genetic Algorithm.…”

In the HVAC system, the required energy consumption is very large so that energy saving processes are needed. One effective method in this energy saving process is the heat recovery process using a Heat Pipe Heat Exchanger. Various studies have been carried out regarding the application of HPHE in HVAC systems to reduce temperature and maintain air humidity. In its application, there are many factors that affect the effectiveness of using this HPHE. Therefore, in this research, an optimization process will be carried out by considering the number of HPHE modules, inlet air temperature, and inlet air velocity. The modelling is performed to predict energy recovery and payback period by using Response Surface Methodology (RSM). Optimization study was conducted to investigate the optimum energy recovery and payback period by varying HPHE parameters experiment.

“…However, exergy analysis has gained importance recently over the first law of analysis due to the failure of the first law of analysis to provide enough results that will aid studying the performance of power plants. Exergy analysis primarily aims at identifying the locations of exergy losses, as well as study power plants in terms of their quality [1,[41][42][43][44][45][46][47][48][49][50][51][52]. Exergy analysis remains a way of locating process or system inefficiencies which first law of analysis cannot do.…”

Exergy analysis has been found to be a useful method for improving the conversion efficiency of energy resources, since it helps to identify locations, types and true magnitudes of wastes and losses. It has also been applied for other purposes, such as distinguishing high- from low-quality energy sources or defining the engineering technological limits in designing more energy-efficient systems. To identify locations, types, and actual magnitudes of energy losses; exergy analysis has been found to be a valuable way for enhancing the conversion efficiency of the different energy systems. The aim of this research is to analyze the effect of the operation conditions on the performance of coal-fired power plants. As well, this study focuses on the effect of different feedwater heaters' numbers that lead to the highest exergy destruction of the coal-fired power plants. For different values of the superheated steam temperature and the pressure, a parametric study was conducted to determine the efficiency of the coal-fired power plant. The results show that, when the pressures and temperature of the superheated steam increases the evaporator temperature will increases too. Increasing the temperature of evaporator rises the average maximum temperature of the cycle, which improves the thermal efficiency of the cycle as well as the powerplant efficiency. The results show that, at higher boiler pressures and temperatures, the temperature difference between the water/steam and hot gases of the boiler is reduced which means the irreversibility associated with the heat transfer process decreases. Therefore, by increasing the pressure and temperature of the superheater, the exergy efficiency of the thermal cycle is improved. It was observed that operating the coal-fired power plant at high superheated pressure and temperatures produce lead to reduce the exergy losses.
