Integration Of Heat Pipe Solar Water Heating Systems With Different Residential Households: An Energy, Environmental, And Economic Evaluation, Abdellah Shafieian, Mehdi Khiadani Jan 2020

Integration Of Heat Pipe Solar Water Heating Systems With Different Residential Households: An Energy, Environmental, And Economic Evaluation, Abdellah Shafieian, Mehdi Khiadani

Research outputs 2014 to 2021

This study presents a detailed methodology for evaluating the energy, environmental, and economic contributions of heat pipe solar water heating (HPSWH) systems in various households. The hot water consumption patterns of Perth residents in Australia in one, two, and four-occupant houses are extracted in hourly basis throughout a year. The annual performance of the system is evaluated based on parameters such as saved energy, solar fraction, avoided CO2 emission, saved money, and payback period. Moreover, an experimental rig is designed, manufactured, and tested. The results show that the contribution of the solar system in meeting the hot water demand …


Enhancing Heat Pipe Solar Water Heating Systems Performance Using A Novel Variable Mass Flow Rate Technique And Different Solar Working Fluids, Abdellah Shafieian, Junaid Jaffer Osman, Mehdi Khiadani, Ataollah Nosrati Jan 2019

Enhancing Heat Pipe Solar Water Heating Systems Performance Using A Novel Variable Mass Flow Rate Technique And Different Solar Working Fluids, Abdellah Shafieian, Junaid Jaffer Osman, Mehdi Khiadani, Ataollah Nosrati

Research outputs 2014 to 2021

This paper aims to improve the overall efficiency of heat pipe solar water heating (HPSWH) systems by implementing a novel variable mass flow rate technique which regulates the solar working fluid mass flow rate of the system with the solar radiation intensity. To analyse the system under real operational conditions, the residential hot water consumption pattern of Perth residents in Western Australia was used in the experiments. In addition, a nanofluid (Al2O3/DI) was fabricated and its performance as the solar working fluid was investigated to find the optimum concentration and to confirm its stability and thermo-physical …


A Novel Solar-Driven Direct Contact Membrane-Based Water Desalination System, Abdellah Sharifian, Mehdi Khiadani Jan 2019

A Novel Solar-Driven Direct Contact Membrane-Based Water Desalination System, Abdellah Sharifian, Mehdi Khiadani

Research outputs 2014 to 2021

This study proposes a novel integrated solar membrane-based desalination system. The system includes vacuum glass tubes to increase absorbed solar energy and to decrease heat loss, heat pipes to transfer the absorbed energy efficiently, and a tubular direct contact membrane distillation module to use the absorbed energy more effectively. To improve the freshwater production rate and overall efficiency of the proposed system, a cooling unit was also added to the permeate loop of the desalination unit. The performance of the system was experimentally investigated without (Case I) and with (Case II) the cooling unit in summer and without the cooling …


Theoretical Modelling Approaches Of Heat Pipe Solar Collectors In Solar Systems: A Comprehensive Review, Abdellah Sharifian, Mehdi Khiadani, Ataollah Nosrati Jan 2019

Theoretical Modelling Approaches Of Heat Pipe Solar Collectors In Solar Systems: A Comprehensive Review, Abdellah Sharifian, Mehdi Khiadani, Ataollah Nosrati

Research outputs 2014 to 2021

The invention of heat pipe solar collectors (HPSCs) is considered as an immense step forward towards solving the challenges of conventional solar thermal systems. Their unique qualities have acted as a great motivation for researchers to focus their studies on HPSCs and their applications. A considerable share of these studies has been allocated to theoretical studies due to several technical and economic reasons. However, to the authors’ knowledge and despite many valuable efforts in this field, there is no review paper available to summarise the relevant proposed and developed theoretical models to date and identifies the research gaps in this …


A Review Of Latest Developments, Progress, And Applications Of Heat Pipe Solar Collectors, Abdellah Sharifian, Mehdi Khiadani, Ataollah Nosrati Jan 2018

A Review Of Latest Developments, Progress, And Applications Of Heat Pipe Solar Collectors, Abdellah Sharifian, Mehdi Khiadani, Ataollah Nosrati

Research outputs 2014 to 2021

Among all the available solutions to the current high energy demand and consequent economic and environmental problems, solar energy, without any doubt, is one of the most promising and widespread solutions. However, conventional solar systems face some intractable challenges affecting their technical performance and economic feasibility. To overcome these challenges, increasing attention has been drawn towards the utilization of heat pipes, as an efficient heat transfer technology, in conventional solar systems. To the authors’ knowledge, despite many valuable studies on heat pipe solar collectors (mainly during the last decade), a comprehensive review which surveys and summarizes those studies and identifies …
