EVENTS AND EXHIBITIONS INCORPORATING COLD CHAIN a selected primary health facility with respect to the use of natural refrigerants used in the application system. (This was discussed at the ‘Climate Friendly RAC Workshop’ in Elsenburg, Stellenbosch which happened a week prior.) Laidlaw raised a concern regarding the South African National Standards (SANS) being out-of-date – something that is holding the industry back, especially with regards to refrigerants. He also said a few words about the SAIRAC Dreosti Memorial lectures with the R290 topic (which took place around the country, ending the night prior to the Elsenburg workshop – also at the same venue). “Reduction of high-GWP substances are vital for life on earth. We only have one world.” – Natasha Kochova, UNIDO He reiterated that the industry isn’t simply just sitting back. “We are being proactive,” he said. “Things are happening.” The presentation also covered the newly-developed air-conditioning refrigeration qualification and the fact that we now have specific modules for natural refrigerants. “We are up to date with our qualifications,” he reported. He also spoke about the refrigeration part qualification and the different routes for getting qualifications in the industry. Safe handling training is the minimum requirement needed to work in this industry, he explained and added that R290 and R600a (hydrocarbons aka a natural refrigerant) have already been included in the safe handling curriculum. So, where do we stand in the quest to the full usage of natural refrigerants? Laidlaw gave the following insights: • Ammonia – well known. • CO 2 – made great strides in the • market, however legislation and standards are not up to speed. Yet we are world leaders in some projects. HCs – had training in GIZ Germany that enabled us to update our own curriculum. The training of female apprentices is regularly brought up by DEFF who says we aren’t training enough. COLD LINK AFRICA • SEPTEMBER 2019 However, Laidlaw confirmed that he’s currently training more than 60 female apprentices, and that more than half of his apprentice intake is female generally. He spoke of our challenges with the uptake of natural refrigerants locally. “We have a lack of industry buy-in; they are reluctant to change,” he explained. The supply chain is also not in place for natural refrigerants to be more popular in the South African RAC sector. In the end, it’s not all bad news though. “We may have challenges, but the South African industry is getting there,” he concluded. REFRIGERANT USAGE IN SA John Ackermann of the Southern African Refrigerated Distribution Association (SARDA) was up next. Ackermann has been very active in the local refrigeration industry and was key in the phase out of CFCs and the ongoing HCFCs. He walked the audience through the history (and the evolution) of refrigerants in South Africa. “Back in the day, the choice of refrigerant was easy,” he said. “Then the Montreal Protocol came along in 1987 and everything changed.” He spoke about our phase- outs after South Africa signed the Montreal Protocol in 1990, and about how industry made the CFC phase-out happen themselves. “Then, suddenly, we had a huge selection of refrigerants, getting more and more confusing,” he remembers. As we phased down CFCs, our HCFC consumption increased… We never had R134a before, now we are completely dependent on it. He spoke about how the registration of safe handling of refrigeration started (initially an Agricsa initiative), the Pressure Equipment Regulations (PER) of 2009, the Kyoto Protocol, and more, leading up to present day. “With the available technology, equipment and skills, we shouldn’t be considering ozone depleting potential (ODP) refrigerants anymore for new installations,” he said. “It’s a crime against humanity to install a new installation with an ODP. The only option is zero ODP. And GWP of less than 1 000 – should be our aim. There are enough options. Also, look at low overall energy usage. It’s no good having low GWP if we’re using an enormous amount of power to run the plant.” Ackermann showed a table of available refrigerants with a GWP below 1 000, speaking about what industry would need to use these new refrigerants – mainly a higher level of skills at all levels. He showed examples of cabinets, projects, and plants charged with natural refrigerants to show how it can be done. “Air conditioning and refrigeration is not a luxury, it’s essential,” he explained, highlighting areas such as food safety and distribution of vaccines. “The battle against global warming by the present generation is to safeguard food security, prevent job losses in the agricultural sector, save communities close to the coast lines and preserve many threatened species of natural fauna and flora,” he said. “Now is the time for the RAC industry to increase its role in fighting global warming. Let the barriers be seen as solutions and let there be gains from the experiences in the phase out of CFCs and HCFCs.” REPORTING REQUIREMENTS The last speaker for the day was Peder Gabrielsen of the European Environment Agency who presented an introduction on data collection and reporting commitments. He started by looking at the European F-gas regulation and history of it, expanding more on the EU licencing system and the F-gas regulation requirements in terms of reporting. He gave a brief overview of the governance model and highlighted a potential way forward and some suggestions that might assist South Africa in our reporting in accordance with the Kigali Amendment. ALTERNATIVES Day two of the workshop kicked off with a presentation by Michael Labacher of A-gas who discussed refrigerant trends and different types of gases available to the industry to replace high-GWP and ODS options. RECLAIMING REFRIGERANTS Ronald Viskil of Unicorn refrigeration tools and equipment in the Netherlands, who supplied and commissioned the four reclamation machines UNIDO donated to South Africa, was up next to talk about ‘reclaiming refrigerants in SA – challenges and opportunities’. He spoke about the benefits and opportunities of banning disposable refrigerant canisters. The Netherlands phased out disposas in 1993 already, and he says even though industry complained greatly initially, “they got over it quickly.” According to Viskil, in most countries, the biggest challenge with regards to phase downs/outs is enforcement and implementation, and people should be fined for using illegal refrigerants. There is a massive problem with companies just venting refrigerants out of systems locally instead of reclaiming. There is a need for a strategy to change this. He spoke about the perceived issues with reclamation and why www.coldlinkafrica.co.za 23
