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 .
