Gallagher Convention Centre, Johannesburg, South Africa

Seminar Programme

Speaker Name:Marius La Grange
Time:10:00 - 11:00
Duration:1.00 hour(s)
Description:
With most commercial and industrial refrigeration systems requiring extensive reticulation as part of the installation, what is required for the design and selection process of the line sizes in each case. This would primarily cover the discharge line sizing from a compressor to a condenser — drain line from the condenser to the liquid receiver — liquid line to expansion device — suction line back to the compressor. The purpose of the session is to assist people involved with planning and design to gain further insight and practical application of the basics for doing reticulation accurately and to save costs with a fully functional system. hour(s)
Speaker Name:John Ackermann
Time:11:00 - 12:00
Duration:1.00 hour(s)
Description:
The MP, signed in 1987, redefined the future landscape of HVAC&R installations. Prior to the MP, the attention given to the environmental impact of HVAC&R systems was minimal and the selection of refrigerant for installations was based mostly on cooling duty and safety considerations. Although safety is still of prime concern, the choice of refrigerant is vastly different and given much more attention by design engineers and plant operators. The search for the ‘silver bullet’ refrigerant with the least impact on the environment, directly and indirectly, will continue for decades to come. As a signatory to the MP and part of the global economic community, South Africa is committed to a reduction in the carbon footprint of all HVAC&R systems in whatever application or configuration. We address the practical implications of the MP and other international environmental agreements on HVAC&R design engineers, service technicians, and plant operators. hour(s)
Speaker Name:Ron Burns
Time:12:00 - 13:00
Duration:1.00 hour(s)
Description:
Smoke barriers are the simplest smoke control requirement. They consume the lowest engineering knowledge and input, and they are the most visible element in a smoke control system. Yet, they remain the most overlooked and disrespected component. Incorrectly positioned, spur of the moment development meeting adjustments to adjust “this unsightly and aesthetically unpleasing” component can have the same catastrophic effect on the smoke control system as an incorrectly installed electrical reticulation system to smoke extraction fans. hour(s)
Speaker Name:Erick Melquiond
Time:13:00 - 14:00
Duration:1.00 hour(s)
Description:
As one of the leading experts in this field worldwide, Melquiond will provide an in-depth introduction to certification, labelling, and what it involves. Among other things, he will outline the benefits of certification and what to consider when relying on it. He will also offer an introduction to ‘Eurovent Certified Performance’, tailor-made for local engineering and mechanical, electrical, and plumbing (MEP) consultants. hour(s)
Speaker Name:Barney Richardson
Time:14:00 - 15:00
Duration:1.00 hour(s)
Description:
The requirements of the Pressure Equipment Regulations, which form part of the Occupational Health and Safety Act, 1993 (Act No. 85 of 1993). An authorised person defined in the regulations means a person who is registered as competent within the scope of work for which an organisation approved by the chief inspector has registered that person. The Department of Labour has mandated SAQCC Gas to achieve this registration. The categories of registration and the training and assessment criteria will be discussed. hour(s)
Speaker Name:Francesco Scuderi
Time:10:00 - 11:00
Duration:1.00 hour(s)
Description:
An introduction to the European regulatory timeframe for HVAC&R products as well as to the technical standards covering those products. The European seasonal efficiency approach for HVAC&R products and how other countries like South Africa can make use of this approach. Among other things, he will also elaborate on the needs of the European industry and how Eurovent supports it both in and outside Europe. hour(s)
Speaker Name:Amir Naqvi
Time:11:00 - 12:00
Duration:1.00 hour(s)
Description:
R22 is a high-capacity refrigerant employed in many medium- and low-temperature refrigeration systems. End users work to comply with present regulations, as well as to reduce their carbon footprint. Existing refrigeration equipment may need to be replaced or retrofitted with an alternative refrigerant. The selection of a retrofit refrigerant depends, in part, upon the retrofit objectives, which may include factors such as efficiency, first cost, regulatory compliance, and capacity. By following equipment manufacturers’ recommendations and Honeywell’s guidelines, service technicians can readily retrofit many existing R22 and R404A systems with the refrigerant gases Honeywell has on offer, including R407F and R448A. hour(s)
Speaker Name:Jaco Botha
Time:13:00 - 14:00
Duration:1.00 hour(s)
Description:
Grid capacity shortage has become a major constraining factor to business growth within South Africa. Recent technological improvements within energy storage have resulted in lower costs of battery solutions, which are proving to be financially viable — creating exciting new possibilities for businesses! We examine the case of a hardware store that was unable to build their new store, as the utility did not have capacity to provide their required daytime load. They successfully overcame the utility supply limitations through the implementation of a solar PV and battery solution integrated with diesel generators. Botha will explore the levelised cost of energy (LCOE) of various alternatives, including the cost implications of larger rooftop versus medium rooftop installations, the additional costs of adding storage capacity through battery solutions, the impact on energy (operational) costs for businesses, as well as the risks and benefits of implementing solar PV solutions. hour(s)
Speaker Name:Charel Marais
Time:14:00 - 15:00
Duration:1.00 hour(s)
Description:
The important aspects of ducting installation, including supports and manufacturing. Adherence to relevant quality standards for both manufacturing and installation. Insulation and application thereof as well as duct work commissioning, including pressure testing and inspection procedures. hour(s)
Speaker Name:Wynand Groenewald
Time:10:00 - 11:00
Duration:1.00 hour(s)
Description:
Global trends on CO2 refrigeration systems being used in the market. Experiences and views on the operation of these systems under different ambient conditions. Future of natural refrigerants such as CO2 according to phase-out legislations and uptake in the market. Possibilities and differences between using CO2 as an alternative refrigerant to HCFCs. hour(s)
Speaker Name:Grant Laidlaw
Time:11:00 - 12:00
Duration:1.00 hour(s)
Description:
New qualifications, their rationale, and curriculums for the trades air conditioning and refrigeration mechanic. The new education system, qualifications, roles, and responsibilities of the various stakeholders will be discussed. A detailed look at the qualification design, specialised areas (ammonia and CO2), and part qualifications. The new trade testing model and the implications thereof will receive detailed attention. This presentation will be of interest to all who operate in the HVAC&R sector. hour(s)
Speaker Name:Carsten Dahlgaard
Time:12:00 - 13:00
Duration:1.00 hour(s)
Description:
Hot gas defrosting methods for evaporators in industrial systems. The focus is on defrosting methods for ammonia air coolers in overfeed systems, especially concentrating on the liquid drain method and its benefits compared to the pressure control method. It also introduces a new defrost solution from Danfoss, leveraging the benefits of the liquid drain method. Recommendations are provided on how to achieve effective and cost-efficient defrost systems, taking into account key design requirements and safety considerations, ensuring the optimal defrost solution for the industry. hour(s)
