Events and Exhibitions John Ackermann came on stage and livened up the room sharing a short story about how he was first introduced to natural refrigerants. Ackermann is adamant that going the natural refrigerants route is the only option. “And there are many options that such a refrigerant offers, there is, water, air, ammonia, CO 2 , hydrocarbons and liquid nitrogen. So, there is no reason why anyone would be sceptical. “We’d better start doing it today; we have only got one option and that means natural refrigerants, no matter which way you look at it,” Ackermann said. Ammonia is used in the industrial sector in South Africa, while there are more than 300 CO 2 systems installed, both subcritical and transcritical. No synthetic refrigerants are produced in South Africa or anywhere else in Africa, so African countries rely solely on imports. As a result, they will have to follow the rest of the world as it bans and phases out f-gases, or risk a ‘day zero’ for synthetic refrigerants, Ackermann said. A day zero would be detrimental to many other sectors, affecting industries like mining, food supply and healthcare. Ammonia is the most developed natural refrigerant technology in South Africa, focused on the industrial sector. “The expertise of ammonia here in this country matches the expertise anywhere else in the world,” he said. “On ammonia, we’ve got the skills, we’ve got the knowledge.” Adopting CO 2 technology has taken longer in South Africa. “We started off with a bit of a slow start in 2008, mainly in the supermarket industry and the wholesale industry, and now transcritical is becoming more popular,” Ackermann explained, before adding that “CO 2 at the moment is the dominant [refrigerant] in the retail supermarket sector.” He stressed that an “enormous amount of research” is being done on natural refrigerants to develop the technologies and address inherent challenges like toxicity and flammability. According to Ackermann, the way forward to changing to natural refrigerants will require safety awareness campaigns, a comprehensive skills training programme, buy in from government in their own installations and lastly, compliance with standards and regulations. Apart from technical challenges Ackermann spoke of more generic barriers, like public apathy to the climate crisis. “Believe it or not, there are still people in our society that say ‘huh, yeah, it’s getting a bit hot eh?’” he joked. Ackermann also accused the air conditioning industry of having a “convenient” lack of awareness of natural refrigerants, and a lack of innovation. End-users in attendance from Spar, Pick n Pay, Woolworths, etc. shared their experience with transitioning to a natural refrigerant. The underlying response that Ackermann highlighted from all their presentations is that, none of them have lost money from going green. www.hvacronline.co.za An exhibition was held during the conference featuring some of the industry leading companies. Attendees were interactive in sharing their experience with natural refrigerants, asking thought-provoking questions and giving advice. FRIGAIR 2021 shecco will be part of FRIGAIR 2021 and looks forward to another interactive discussion around the topic.
