About World Refrigeration Day
World Refrigeration Day is observed on June 26 as an international awareness campaign for the refrigeration, air-conditioning and heat-pump sector and the role temperature-control technology plays in modern life.
The campaign is coordinated by the World Refrigeration Day Secretariat with participation from professional bodies, institutions, businesses and individuals.
Why World Refrigeration Day matters
The day makes the often-invisible work behind cooling and sustainable heating more visible, including links with food, health care, buildings, transport and digital infrastructure.
It is an awareness campaign, not a universal technical code. Refrigerant handling, electrical work, pressure systems, licensing and compliance requirements vary by jurisdiction and should be left to appropriately qualified people.
History of World Refrigeration Day
The organizer says the idea came from refrigeration consultant Stephen Gill, a former president of the UK Institute of Refrigeration.
The inaugural World Refrigeration Day was held on June 26, 2019, with the organizer reporting more than 800 physical events in at least 153 countries.
The Secretariat continues the campaign; in 2026 it ran the “Cool Intelligence” theme and continued related community activity beyond June 26.
