Petra Sponsors World Refrigeration Day 2021

Petra is again proud to sponsor World Refrigeration Day which is held annually on June 26th.

Refrigeration, air conditioning and  heat pumps have a vital role in modern life helping to promote health, comfort, environmental sustainability and economic prosperity.  June 26th is an opportunity for those within and outside the RACHP industry to come together to learn, share knowledge, build connections and find opportunities to collaborate to improve modern life


World Refrigeration Day is held on the 26th June every year in recognition of  William Thomson, 1st Baron Kelvin, (26 June 1824 – 17 December 1907), a British mathematical physicist and engineer.  Whilst at the University of Glasgow he did important work in the mathematical analysis of electricity and formulation of the first and second laws of thermodynamics, and did much to unify the emerging discipline of physics in its modern form.

Absolute temperatures are stated in units of kelvin in his honour.  While the existence of a lower limit to temperature (absolute zero) was known prior to his work, Kelvin is known for determining its correct value as approximately −273.15°C.

World Refrigeration Day

World Refrigeration Day is an international awareness campaign to raise the profile of the refrigeration, air conditioning and heat pump sector and focuses attention on the significant role that the industry and its technology play in modern life and society. It draws attention to wonderful engineering and science that is all around us every day.

World Refrigeration Day gives us the opportunity to raise awareness and understanding of the significant role that the refrigeration and air conditioning industry, and the associated science and technology play in modern life and society in a safe and responsible manner that is fully compliant with local regulations and aligned to all safety measures.

The theme for 2021 is raising awareness of the people that work inside this hidden industry – the #coolingchampions and the #coolcareers that this industry offers

For this year’s campaign, OzonAction and the WRD Secretariat are joining with key international partners: ASHRAEEuropean Partnership for Energy and the Environment (EPEE), Federation of Ibero-American Air Conditioning and Refrigeration Associations (FAIAR), International Institute of Refrigeration (IIR), Indian Society of Heating, Refrigerating and Air-Conditioning Engineers (ISHRAE), and Union of Associations of African Actors in Refrigeration and air-Conditioning (U-3ARC).

Refrigeration is at the very heart of modern life. Some 15 million people are employed worldwide in the refrigeration sector. The total number of refrigeration, air-conditioning and heat-pump systems in operation worldwide is around 5 billion. Those systems provide the conditions we require for health, comfort, work productivity, manufacturing, as well as essential environments for food, pharmaceuticals, and digital data. Dedicated professionals design, build, maintain, and regulate them and also train and educate a new generation of practitioners. Their work is essential for the success of the Montreal Protocol on Substances that Deplete the Ozone Layer since many of the refrigerants they work with are ozone depleting and/or contribute to climate change.

For the last three decades, in UNEP’s capacity as an Implementing Agency of the Protocol’s Multilateral Fund, OzonAction has been at the heart of the battle to promote best practices and state-of-the-art technologies for the refrigeration and air-conditioning sectors to eliminate the use of ozone depleting substances and minimize the use of high global warming potential substances. It continues to assist developing countries with building capacities, certifying servicing technicians, developing local standards/codes, and advancing the use of sustainable ozone/climate-friendly technologies. OzonAction cooperates closely with refrigeration and air conditioning associations as well as refrigeration environmental experts to deliver these services.

Through the WRD-2021, UNEP OzonAction will cooperate with the campaign partners to shed light on areas, dimensions and opportunities that future refrigeration and air-conditioning engineers, practitioners and experts need to consider for the industry to engage in a better society and sustainable communities. It is also hoped that the campaign will encourage more women and men to become interested in this sector – including its environmental protection dimension – as their professional career path.
