IIR launched a new technical brief on dehumidification at the OEWG48 side event in Bangkok

The International Institute of Refrigeration (IIR) officially launched its latest technical publication, Dehumidification in Air Conditioning, at a side event during the 48th Meeting of the Open-Ended Working Group (OEWG48), taking place in Bangkok. 

 

Sponsored by the Chinese Association of Refrigeration, the side event marked the official launch of the IIR's new technical brief, which reviews the full landscape of dehumidification technologies used in air conditioning, from established condensation and desiccant systems to emerging membrane-based approaches. The session featured presentations by the brief'sauthors and co-editors, followed by a structured discussion on technology selection, energy efficiency challenges, and opportunities for international collaboration. 

 

Why it matters 

 

Dehumidification is responsible for more than half of the cooling load and the associated energy use in many air conditioning systems, particularly in hot and humid climates. As cooling demand accelerates across Southeast Asia and other tropical regions, efficient humidity control is increasingly recognised as key to limiting the energy and climate impact of that growth. The event brings together researchers, industry and policy voices to discuss how faster deployment of efficient dehumidification technologies can support both climate mitigation and adaptation goals under the Montreal Protocol.

About the publication 

 

Dehumidification in Air Conditioning is the 62nd in the IIR's Technical Brief series on refrigeration technologies. It reviews condensation, liquid desiccant, solid desiccant and emerging dehumidification technologies, comparing their energy performance, dehumidification capability and technological maturity, and sets out recommendations for both industry and policymakers on accelerating efficient dehumidification, particularly in hot, humid regions where cooling demand is growing fastest.
