Samsung Electronics Co. Ltd. unveiled its latest innovations in Heating, Ventilating and Air Conditioning (HVAC) engineering during a roadshow which started in Cape Town, on the 8 March, 2016, followed by a roadshow in Zimbali, KwaZulu-Natal on 11 March 2016 and an event at Montecasino, Johannesburg on 16 March 2016.
A water-based under floor heating system is a series of interconnected pipes that circulate warm water throughout the floor to heat up the space. Pipes can be connected to a boiler or a solar water heating system. The water temperature to the heating pipe is controlled by mixing the water in the pipe with hot water from the boiler to achieve the required temperature; this is then passed to a manifold for distribution to the various zones.
The V&A Waterfront’s Silo District is recognised as one of the most advanced and environmentally-friendly developments in Africa, as the completed No 1 and No 2 Silo developments use the waters of the Atlantic Ocean in the surrounding harbour to provide cooling and heating to the R2.5-billion project, which is due for completion in 2017 once an additional four silo developments are fully-operational.
ThermoWise, specialists in energy saving systems, recently completed the installation of 13 air-to-water heat pumps at the Zibambeleni old age home in Durban, to optimise electricity savings at the establishment.
Ceiling fans deliver powerful environmental effects for every room. They’re decorating essentials too, helping to complete the look of a room. If you haven’t considered specifying ceiling fans in a while, Solent Trading has five reasons for you to consider.
It is important that traffic doors combine functionality with longevity. In areas where the movement of pedestrians and goods is particularly high, consideration to the durability of the door needs to be balanced with its ability to provide an unhindered flow of traffic.
The upgraded water-cooled magnetic centrifugal chiller, introduced by York, with a capacity from 755 to 1355kW is suitable for very large applications. By way of example there are currently nine installed at FNB headquarters in Johannesburg. Responsible for delivering improved efficiency of between 3.5 and 5% is the incorporation of a new variable speed drive (VSD).
ThermoWise designs, manufactures and installs horizontal and vertical calorifiers, engineered to deliver hot water safely and economically in diverse sectors.
Choosing the right technology and installer is essential if one is to realise the potential savings on electricity and reduce environmental impact.
The LG Electronics South Africa Academy (LGESA) is a dedicated, high tech, training and skills development facility, with centers in three major cities, Johannesburg, Cape Town and Durban.
BioFire Fireplaces joined the South African marketplace at the end of 2010, responding to a real demand for ecologically-friendly and electricity-independent heating in South Africa. As the costs of electricity and gas continue to escalate, wood offers an appealing and cost-effective alternative and it is a renewable resource, growing in abundance around the country. A BioFire fireplace uses, on average, only 18 pieces of wood a day, to generate hours of heat for the home. Consider how much this could save you in terms of gas or electricity usage.
RBA Homes handed over the keys for a brand new home to Lucky Mathibela and his family on Friday 1 June 2012, making good on its promise made on 94.7 FM Highveld Stereo’s Christmas Wish campaign. When RBA Homes was approached by 94.7 Highveld Stereo’s Breakfast Show and heard Lucky’s story, it welcomed the chance to make a difference in his life. RBA Homes was impressed by the young man’s positive spirit and his desire to give back to his community as a teacher – even though he was struggling himself.
Ice Cool, flagged as the premium insulating window film from Solashayde, admits “all the light with none of the weather”. When natural light and temperature and solar control are priorities, this is the best window film to use. Ice Cool assists in keeping interiors warm in winter and cool in summer, while letting through bright, visible light. It can be used in offices, homes and any other buildings.
Johnson Controls Building Systems has introduced a series of VP1000 pressure-independent control valves that promise to reduce the installation and commissioning costs for smaller fan coil and air-handling air-conditioning units. “Traditionally, two separate valves are installed to regulate the flow and pressure of water through the air-conditioning units in response to the demands of a controller. The VP1000 valve performs the functions of both valves, with a differential pressure regulator and a regulating valve for flow adjustment. It is easier to install, more cost-effective and requires less maintenance,” explains Neil Cameron, general manager at Johnson Controls Systems & Service South Africa.
The Frigair Expo & Workshop – Africa’s only dedicated heating, ventilation, air-conditioning and refrigeration exhibition and workshop – forms part of the line-up of interrelated events scheduled to run in parallel with The Star Interbuild Africa 2012 exhibition. It will take place 15 to 17 August at the MTN Expo Centre at Nasrec in Johannesburg. The HVAC & R industry and the technologies and systems it designs, installs and maintains are often not visible. They are just there, in the background. But they are essential to keeping people comfortable with cool and fresh air, keeping produce as fresh as when it was harvested, safe for human consumption, and well displayed in supermarkets, delicatessens and the like.
The newly legislated SANS 10400-XA: 2011 and SANS 204: 2008 introduce the requirement for proof of compliance with the standards set out for energy efficiency in buildings. This means that architects and building developers need to ensure that new buildings and building refurbishments are designed to meet the prescribed energy efficiency standards; that a building’s performance in terms of energy usage is calculated and documented; and that the building is built to perform accordingly. Thermal insulation materials – for roofs, walls and floors – constitute a key element in building to achieve the required thermal resistance values (R-values) as set out in SANS 204.
