A closer look at solar assisted cooling

With a case study as evidence, Arne Heuzeroth and Kazuhide Ishida argue that SAC is a sustainable alternative, as solar thermal absorption chillers improve energy efficiency of compression cooling plants.

To LEED or not to LEED – Part 1

In this two-part series, Sougata Nandi analyses four LEED-certified projects in Dubai as benchmarks and assesses how far LEED certification credits are applicable and viable in the region.

The cost of keeping cool

Data centres focus on improving the efficiency of IT equipment. But it is equally important to look at the bigger picture and assess the cost of cooling requirements, says Rajiv Sivaraman

Taking the heat off

Heat exchangers represent the most basic yet fundamental feature of any air conditioning and refrigeration process. Still, this market segment is often overlooked. Valeria Camerino sheds some light on the latest trends, technologies and applications for this key HVACR component.

Time for tough ‘DCsions’

Citing successful examples of district heating in Europe and South Korea, George Berbari interrogates why the models cannot be replicated for district cooling in the region.

‘Some technicians are following wrong procedures’

Valeria C. looks at the myriad issues surrounding the compressors industry

Harnessing the sun to cool the Cup

Innovatively exploiting solar power to control the climate of the stadia in Qatar will not only make the World Cup carbon-neutral, but also pay dividends beyond

At a crossroads

The lingering downturn offers the ideal opportunity to the HVAC industry on how to approach the comfort-cooling needs of the region

From Farm to Fork

What we eat traverses great distances. Safeguarding against contamination & disease is the onus of everybody involved.

Condensate blockages – fix now or pay later

Air conditioning units with blocked or poorly maintained condensate drain lines damage property and affect indoor air quality. Installing traps, overflow switches and switches with integral pumps, coupled with a regular maintenance regimen will prove economical in the long run, says Gerry Spanger.
