Presenter: Wynand Groenewald (CRS)
Topic: Global trends in CO 2 refrigeration
systems
Summary: Groenewald is the technical
director of Commercial Refrigeration
Services (CRS) and spoke on his extensive
experience with natural refrigerants,
focusing on CO 2 in particular. He kicked
things off with looking at the global
movement towards naturals, touching
on global regulations, and the effect
these are having on refrigerant prices. He
looked at the size of the CO 2 market in the
world, highlighting the number of systems
in various countries (South Africa has
102) and taking a quick trip through the
history of this development. Groenewald
then spoke about the future of natural
refrigerants and the estimated growth
potential globally, before moving
on to recent CO 2 developments,
highlighting how the system compares
to various synthetic alternatives currently
in use.

Presenter: Grant Laidlaw (SAIRAC)
Topic: New QCTO qualifications for artisans
in the HVAC&R sectors
Summary: The session of Grant Laidlaw,
president of SAIRAC, was overflowing
with attendees. He gave a breakdown
of the new Quality Council for Trades
and Occupations (QCTO) qualifications
for artisans in the air-conditioning and
refrigeration sectors. Laidlaw said that
this is a South African first, having an air-
conditioning mechanic qualification. Being
heavily involved in setting up the new
curriculum, he explains that the qualification
is three to four years and is on par with
international standards. “We worked really
hard to ensure this. After going through
the course, individuals will qualify as a
refrigeration mechanic in ammonia,” he
said. He encouraged attendees to speak
to the association. “Let’s get the youth
educated.” (Read more about this topic in
Laidlaw’s recent RACA Journal contributed
article on the matter.)
Presenter: Jaco Botha (Solareff)
Topic: Energy storage – an enabling and
disruptive technology that is changing the
energy landscape
Summary: Jaco Botha, CEO of Solareff,
was the last speaker of the day,
discussing energy storage and how it is
an enabling and disruptive technology
that is changing the energy landscape.
He used the Clearwater Mall project as
an example. “The system at the mall saw
energy demand decrease significantly,”
he said. He gave a comparison between
nuclear, coal, and solar, citing that
solar has more environmental benefits.
According to Botha, if solar is installed
on roofs in Gauteng and surrounding
provinces, these can supply electricity to
the world. CLA
