Bio
Dr. Abraham J. Lee is an R&D Associate Staff in the Building Equipment Research Group at Oak Ridge National Laboratory. His research focuses on developing advanced HVAC systems and sustainable cooling technologies. His work involves a combination of experimental investigations and numerical modeling to improve system performance and energy efficiency.
From 2023 to 2024, Dr. Lee assessed the performance and develop a model for a two-phase immersion cooling system in data center applications using a novel low-GWP fluid. This research aims to support the adoption of environmentally friendly and efficient cooling technologies. Previously, he completed his PhD in Mechanical Engineering at Oklahoma State University in 2023, where he studied the performance-and-charge characteristics of heat exchangers using low-GWP refrigerants like R468C and R1234yf and developed an optimization framework to enhance cooling capacity and reduce refrigerant charge.
Dr. Lee's professional background includes five years as a Senior Research Engineer at LG Electronics, where he worked on residential ductless split air conditioners, microchannel heat exchangers, shell-and-coil heat exchangers, and absorption chiller absorbers. He also has experience as a Thermal Design Engineer at Seoul Semiconductor, where he focused on improving the thermal performance of LED packages. He earned his master’s degree from Korea University, where his research involved modeling mass and heat transfer in multiphase porous materials. Dr. Lee continues to engage in projects aimed at improving the efficiency and sustainability of HVAC and cooling systems.
