Striking the right note

Engineers at London’s Grade I-listed Royal Albert Hall had the challenge of designing a near-silent cooling system in one of the UK’s most important Victorian buildings. Andy Pearson listens in

Rethinking the fan coil

The Artus hybrid air conditioning unit is only 200mm deep, yet it achieves energy savings of 83% over conventional fan coil units thanks to patented designs for the heat exchanger and fan assembly. Andy Pearson speaks to inventor Roger Olsen about his quest to cool buildings more efficiently

Gree’s award-winning net zero carbon cooling solution

Air conditioning giant Gree has been recognised as joint winner of the 2021 Global Cooling Prize for creating an air conditioning prototype with five times less climate impact than a standard product. Gree UK’s Tim Boxall reveals the innovations behind its winning solution

Cooling’s pathway to net zero

For the UK to achieve net-zero carbon emissions by 2050, the cooling industry must radically improve the efficiency of equipment and switch to ultra-low global warming potential refrigerants. Andy Pearson looks at a proposed timetable for action

Guide to low loss headers

Achieving hydraulic separation through well-designed low loss headers is key for efficient heating and cooling systems. David Palmer and Baxi Heating’s Ryan Kirkwood provide detailed design guidance, including a recommended system configuration

Handling Covid risk in thermal wheels

To minimise the risk of Covid-19 transmission in thermal wheels, designers should choose a configuration that minimises recirculation of contaminated air. FläktGroup’s David Black explains the options and how AHU purge sectors can cut the risk further

Refrigerant rethink: measuring the environmental impact of HVAC

Specifiers need to start assessing a refrigerant’s embodied carbon as well as its global warming potential, says Klima-Therm’s Tim Mitchell, who is working with bodies such as LETI and CIBSE to calculate the full carbon impact of HVAC systems
