Coolest Day of the Year – 26 June

World Refrigeration Day raises awareness and understanding of the significant role that the refrigeration, air-conditioning and heat-pump industry and its technology play in modern life. The science, engineering, and application of cooling touches our lives in many ways, making hot climates habitable, allowing for storage and delivery of fresh food, giving us productive work and learning spaces, enabling the manufacture of products and the operation of data centers in thermally controlled environments, and preserving medicines and other essentials for healthy living. June 26th is the birthdate of Lord Kelvin, after whom the absolute temperature scale is named.
