EDUCATIONAL LINE-UP Although this year ’ s exhibition was not able to host the ASHRAE workshops owing to

unforeseen circumstances , the owners and organisers have earmarked these courses as a specific highlight for the 2025 experience . Be sure to look out for information related to these courses in future .

The South African Institute for Refrigeration and Air Conditioning ( SAIRAC ) did however execute the hosting of 10 freeto-attend workshops during FRIGAIR 2022 . These included local speakers from industry and government that primarily gave updates to some key elements in the industry from a regulatory , training and process perspective , as well as sharing of experience on best practices and technology aspects . Two international specialists were also involved who offered up their expertise to discuss the very impactful topics around HVAC & R systems . These free-to-attend workshops were well attended .

The speaker presentations ( where agreed in their work being shared freely ) will also be showcased in future . The 2022 workshops included the following topics :

• Refrigerants safe handling , registration of authorised refrigeration practitioners , categories of registration , the registration and renewal processes , time frames and limits . Requirements , roles , and responsibilities . Presented by Barney Richardson of SARACCA .

• Certificates of Conformance ( CoC ) for refrigeration / air conditioning systems in line with the pressure vessel regulations . Registration for , and issuing of , the new online certificates of conformance . Presented by Eddie Cooke and Virginia Mtshali – SAQCC Gas .

• The South African signing of the Kigali amendment , phase down / out of HCFCs and HFCs , and an update on the South Africa ’ s HCFC Phase-Out Management Plan ( HPMP ). Presented by Margaret Molefe of DFFE .

• Installation of insulated structures : aspects of design , common types of insulation used for cold structures and clean rooms , planning and installation , quality control , on-site inspections and approval of works . Presented by Archie Steyn of African Cooling Systems .

• Energy efficiency in hydronic cooling distribution systems . In general , the topic dealt with in this workshop was energy efficiency in central airconditioning ( cooling ) hydronic systems from the centralised production site to local sub-stations and terminal units . Architecture of chilled water distribution systems and the design and installation of heat pumps and polyvalent heat pumps was covered . Presented by Luigi Rossettini ( international speaker ) from Aersa / Aermec .

• Servitisation in refrigeration and how it supports the use of natural refrigerants and shifts the focus sharply to life-cycle cost . Servitisation is a well-known tool in many industries and is a relatively new concept in refrigeration known more commonly as Cooling as a Service ( CaaS ). Preented by Dawie Kriel of Energy Partners .

• The status quo of air conditioning and refrigeration training in South Africa . It covered the latest qualification outline and addressed regular questions involving natural refrigerants , flammable hydrocarbons , apprenticeships , qualifying staff , trade testing , and future training changes and additions . Presented by Grant Laidlaw of ACRA .

• Driving a circular economy and the latest refrigerant trends . The topic included the use and disposal lifecycle for refrigerants and why there is a need to change our outlook on how we deal with refrigerants ( phaseout and quota mechanism ). Presented by Werner Terblanche from A-Gas South Africa .

• Prevention by design educated participants about the basic elements of SANS 893 : Legionella … , as it relates to evaporative cooling equipment . Using the specific written guidance of the SANS 893 documents , it was demonstrated how the proper design , operation and maintenance of evaporative cooling equipment helps to reduce hygiene risks and facilitate better compliance with the guidance and recommendations of SANS 893 . Presented by Robert Downey ( international speaker ) from Baltimore Aircoil Company .

• Using plate heat exchangers in closed circuit cooling towers to save on OPEX and CAPEX highlighted the cost saving benefits of using plate heat exchangers as a substitute for coils . Presented by Louw Nagel of Industrial Water Cooling .
