The following is the transcript of a presentation by John Ackermann – previous editor and founder of this publication – on the impact of the cold chain, commemorating World Refrigeration Day on 26 June. It is Part 1 of a four-part series.
On this World Refrigeration Day, stakeholders from the South African Institute of Refrigeration and Air Conditioning (SAIRAC) gathered to highlight their ongoing efforts in promoting sustainable practices within the refrigeration and air conditioning (RAC) sector. The event, hosted by Sally Denson from the Department of Environmental Affairs and Development Planning, aimed to underscore the critical role of HVAC&R technologies in climate change mitigation.
The session commenced with an overview of SAIRAC’s collaborative initiatives, emphasising their alignment with national and international environmental goals. Denson outlined how SAIRAC’s work intersects with the Air Quality Management Act, stressing the imperative to reduce greenhouse gas emissions and ozone-depleting substances.
“It all started with the Montreal Protocol in 1987,” Denson explained, referring to the landmark agreement that identified the harmful effects of ozone-depleting substances used in HVAC&R systems. She highlighted subsequent international agreements, such as the Kigali Amendment in 2016, which aims to phase down hydrofluorocarbons (HFCs), potent greenhouse gases used as refrigerants.
The presentation underscored the ubiquitous presence of RAC appliances in everyday life, from household refrigerators to commercial cooling systems. Denson pointed out that while these technologies are essential, their environmental impact necessitates careful management of refrigerant gases.
SAIRAC’s flagship project, in partnership with Bavaria since 2016, focused on transitioning to natural refrigerants with lower global warming potentials. This initiative not only aims to reduce emissions but also promotes energy-efficient practices across the sector.
Key achievements highlighted during the session included collaborative workshops and training programs designed to educate technicians on the safe handling of natural refrigerants. Denson praised the partnership with West Coast College, where a dedicated hydrocarbon laboratory now trains technicians in sustainable RAC practices.
As her presentation concluded, Denson invited questions and suggestions from attendees, encouraging ongoing dialogue on sustainable RAC solutions. The session exemplified SAIRAC’s commitment to driving awareness and action on World Refrigeration Day, urging stakeholders to consider the environmental impact of RAC technologies in their daily lives.
