The 1st conference was held at IET Birmingham Austin Court in 2018. The name of this conference was 1st IIR International Conference on the Application of HFO Refrigerants.
This second conference, HFO2021, will provide up-to-date information on the experience and use of HFOs and low GWP blends globally. It will be recognized worldwide as a cutting-edge event to alleviate the current global environmental issues including global warming and climate change. The international participants of this conference will be researchers, engineers, and practitioners, who gather to bring their latest developments and key technology trends all HFOs and low GWP blends for the future refrigeration and air conditioning fields.


The program will include the themes of:

• Physical properties (general, chemical properties, chemical processes, thermophysical properties, equation of state, material compatibility, solubility, etc.)
• Transfer processes (heat and mass transfer, two phase flow, heat exchanger, heat transfer enhancement, secondary refrigerant, etc.)
• Application (cycle simulation, equipment, foaming agent, heat insulating material, solvent, spray, etc.)
• Environment and Regulations (regulations and standards, environmental issues, etc.)
