US Response to International Trends
IEA projects space cooling energy
demand to grow by over 4 times in
non-OECD countries and 1.5 times
for OECD countries by 2050
•
R&D on more efficient cooling and
refrigeration technologies.
•
Proposed new IEA HPT Annex on
"Comfort & Climate Box" for cooling-
dominated climates,
Annex 53 on advanced
cooling/refrigeration technology
development.
Future Path
1:
Advanced Vapor Compression with
Low or Ultra-Low GWP
Refrigerants*
Future Path
2:
Non-Traditional Technologies
(Zero-GWP)

*Naturally occurring fluids may be the only
options for compression-based
technologies by 2050
