Thermal Systems Research Group

The Thermal Systems Research Group (TSRG) is part of the Department of Mechanical Engineering at IIT Delhi. Our research focuses on developing innovative and practical solutions to improve the utilization of thermal energy in our built environment. Thermal energy constitutes a major fraction of all energy conversion and utilization processes. Consequently, it is also one of the major contributors to overall carbon emissions. Our research, driven by the fundamental understanding of thermodynamics, fluid mechanics, and heat and mass transfer, is founded on the belief that many of the existing thermal processes around us can be revolutionized to achieve significantly lower emissions and enable rapid adoption of renewable and clean power sources. We use first-principles based modeling and detailed experiments to develop new concepts for the following applications.

• Membrane and liquid desiccant dehumidification systems for HVAC

• Thermal energy storage technologies

• Thermochemical/Chemisorption heat pumps

• Control of thermo-fluid systems 

• Sustainable buildings and communities 

• Heat recovery in industrial processes
