In this virtual side-event at the 43rd Meeting of the Open-ended Working Group of the Parties to the Montreal Protocol (OEWG), we talked about the global window type air conditioner market and its Green Cooling potential.
Despite the increasing market growth of split-type air conditioners, window-type ACs still have stable markets in many regions, accounting for about 13 million sales annually. Most of these sold units are featured with a low energy performance and highly climate-damaging HCFC-22 (GWP 1800) and HFC-410A (GWP 2088). However, their compactness, small refrigerant charge and simple installation perfectly qualify them for HC-290 (GWP of 1), holding large efficiency and climate benefits on scale.
In this side event we zoomed into most dominant regional markets, unfolded the GHG mitigation potential that would result from a timely transition to HC-290 (GWP of 1), and discussed design and safety aspects of R290 window-type ACs.
The side event provided insights in the Green Cooling potential of window type ACs.
