Barney Richardson, director of SARACCA |
Richardson is the director of the South African Refrigeration and Air Conditioning Contractors Association( SARACCA) and sits on various other boards within the HVAC industry, including the South African Qualifications and Certifications Committee for Gas( SAQCC) Gas. |
Registration of authorised refrigeration gas practitioners. |
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. |

Francesco Scuderi, deputy secretary general of Eurovent Certita Certification |
Scuderi holds a master’ s degree in electrical energy engineering from the University of Catania. Before starting at Eurovent in 2015, Scuderi worked for the EPTA Group( a global industry leader specialising in commercial refrigeration), gradually progressing to being in charge of the Group Regulatory Affairs and IP. Later on, he became the convenor of the ISO / TC86 / SC7 / WG2 and CEN / TC44 / WG6‘ Commercial beverage coolers and ice-cream freezers’. Having specialised in European legislation, Scuderi, one of the European leading experts in the refrigeration field, joined Eurovent as technical and regulatory affairs manager for the heating and cooling department, as well as horizontal issues such as energy labelling, the f-gas regulation, and market surveillance. In May 2017, he was appointed Eurovent Association deputy secretary general. |
An insight towards the European regulatory timeframe for HVAC & R products and the work of the Eurovent Association. |
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. |

Refrigerant alternatives to R22. |
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. |

Energy storage— an enabling and disruptive technology that is changing the energy landscape. |
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.
