Post Doctoral Researcher within the refrigeration group at the Department of Energy and Process Engineering. My research is focused on the energy efficiency improvement of CO2 transcritical refrigeration systems for hotel, food storage, and freezing applications. Also, I work as a project coordinator for The Future Refrigeration India: INDEE+ project.
The Future Refrigeration India: INDEE+, is an ongoing Indo-Norwegian project funded by the Ministry of Foreign Affairs (MFA) Norway, coordinated by the Norwegian University of Science and Technology (NTNU), Norway. INDEE+ aims to demonstrate eco-friendly natural refrigerants (such as: ammonia (NH3), carbon dioxide (CO2), and hydrocarbons) to promote a clean, sustainable, and reliable heating and cooling solutions for the future heating, ventilation, air conditioning and refrigeration (HVAC&R) sector in India. The outcomes of INDEE+ will support India’s commitment to achieving the goals of ratifying the Kigali Amendment of the Montreal Protocol and Paris Agreement on climate change.
