Thermal Energy Waste Recovery Technologies and Systems

Dr. Chen Weidong is currently a research fellow from the Department of Mechanical Engineering, National University of Singapore (NUS). He completed his undergraduate coursework at Tongji University, during which time he received the first prize scholarship every year and won the Outstanding Graduates of Shanghai in 2018. As the recipient of the NUS research scholarship, he started his Ph.D. in Mechanical Engineering from NUS in 2018, under Prof. Kian Jon Chua's supervision. During his doctoral training, he focused on the experiment and simulation investigation of a multi-generation system to achieve improved energy performance. The multi-generation system is able to high-efficiently produce electricity, cooling, heating, potable water, dry and cool air by harnessing waste thermal energy. So far, he has published six research papers in the top journal of Applied energy (APEN), Energy conversion and management (ECM), and Energy. His specific research focus areas include CCHP, waste heat recovery, temperature cascade utilization system, adsorption chiller, absorption chiller, multi-objective optimization, optimal operating strategy analysis, and system simulation by employing Monte Carlo simulation and Simulink platform.Mr. Huang Zhifeng is currently pursuing his Ph.D., as the recipient of the prestigious NUS Graduate scholarship, in the Department of Mechanical Engineering, National University of Singapore (NUS) under Prof. Kian Jon Chua's supervision. He received his Bachelor's and Master's degrees from SCUT, China and worked as an engineer in South China Power Gird for three years. During his doctoral training, he designed a series of advanced systems to improve the energy utilization efficiency and recovery rate for LNG cold energy, as well as experiment on a cascading LNG cold energy recovery experimental setup in the lab. His research findings have been published in various top international journals, including Applied energy, Energy conversion management, and Energy. Huang's specific research areas focus on gas turbines, co-generation systems, tri-generation systems, waste heat recovery, and waste cold energy recovery.Dr. Chua Kian Jon is an Associate Professor with the Department of Mechanical Engineering, National University of Singapore. He has been conducting research on air-conditioning, refrigeration, and heat recovery systems since 1997. He has conducted both modelling and experimental works for specific thermal energy systems, including dehumidification, cooling, heat pumping, compact heat exchangers and refined temperature/humidity control. He is highly skilled in designing; fabricating; commissioning and testing many sustainable energy systems to provide for heating, cooling and humidity control for both small- and large-scale applications.Dr. Chua has published over 200 international peer-reviewed journal publications, 6 book chapters, and two recent monographs on advances in air conditioning and dehumidification technologies. He was highlighted to be among the top 2% of global energy scientists based on Elsevier’s database, 1% of scientists in the world by the Universal Scientific Education and Research Network, top 0.3% in the Stanford list of energy researchers. He has been elected to several fellowships including Fellow of Institute of Mechanical Engineering, Fellow of Royal Society, and Fellow of Energy Institute. His works has garnered more than 11,500 over citations with a current h‐index of 56. Further, he owns more than 15 patents related to several innovative cooling and dehumidification systems. He is the Principal Investigator of several multi-million competitive research grants. Additionally, he has been awarded multiple local, regional, and international awards for his breakthrough research endeavours.
