www.heatpumpingtechnologies.orgOVERVIEW IEA HPT ANNEX 54
• Objectives:
– Promoting application of low-GWP refrigerants to accelerate phase down of
high-GWP HFCs
– Developing design guidelines of optimized components and systems for low-
GWP refrigerants
• Scopes:
– Review of low-GWP refrigerants, their properties and applicable standards
– Review of safety and flammability of refrigerants, and safe use of flammable
refrigerants
– Optimization of heat pump components and systems for low-GWP refrigerants
– Analyze the LCCP impacts by the current design and optimized design with
low-GWP refrigerants
– Make an outlook for Heat Pumps with low-GWP refrigerant for 2030
www.heatpumpingtechnologies.orgSUCCESS STORIES/ACHIEVEMENTS/KEY FINDINGS • Since Annex54 successfully started in 2019 with four member countries, four new member countries joined in 2020. • Annex 54 successfully complied 2019 Country report. • 2019 Country report provides a comprehensive, most up-to- date review of current research, product development and regulation status of low-GWP refrigerants for the heat pump application. It summarizes the collective efforts by researchers, engineers and regulation committees across the industry. www.heatpumpingtechnologies.org
ACHIEVEMENTS IN THE ANNEX • Recruited four more member countries • Completed 2019 country reports for Task 1 • Planning two workshops and two business meetings in 2020 www.heatpumpingtechnologies.org
ANNEX ACTIVITIES SINCE LAST EXCO REPORT
• Since the last ExCo meeting held in Gaithersburg, MD, US in November
2019, four countries joined the Annex 54.
• Collected draft country reports for Task 1: Review of state-of-the-art
technologies, created 2019 country report, received comments from
members, revised according to comments by members and submitted to
ExCo in April 2020
• Planned to participate in the 13th IEA Heap Pump Conference (HPC), Jeju,
Korea
• Planned the Workshop with seven speakers to present Annex 54 activities
during the HPC
• Planned a third meeting during the HPC to discuss tasks and progress
status among members
www.heatpumpingtechnologies.orgPLANNED ACTIVITIES
• A fourth meeting of the participants and observers, and
fourth workshop are planned in December 2020 in Kyoto,
Japan during the 14th Gustave Lorentzen Conference.
• 2020 annual country report will be prepared and complied.
• A fifth meeting and fifth workshop are planned in April 2021
in Jeju, Korea during the HPC.
• Other possible meetings:
– 2nd IIR Conference on HFO Refrigerants and Blends (HFO 2021)
– 6th IIR Conference on Thermophysical Properties and Transfer
Processes of Refrigerants (TPTPR 2021)
