The International Institute of Refrigeration (IIR), to celebrate the world’s first Refrigeration Day, published an Informatory Note on “The Role of Refrigeration in the Global Economy.” In it, the IIR estimates that the total number of refrigeration, air conditioning and heat pump systems in operation worldwide is roughly 5 billion, with global annual sales of such equipment amounting to approximately $500 billion.

An update of a first version published in November 2015, this 38th IIR Informatory Note summarizes basic data illustrating size and reach of the refrigeration sector. It aims to raise policy makers’ awareness on the growing importance of refrigeration in order to further encourage its development in a sustainable manner.
