Chiller upgrade for iconic London venue
Carrier Commercial HVAC recently completed a chiller replacement project at one of London’s most extraordinary venues, the ArcelorMittal Orbit in Queen Elizabeth Olympic Park, Stratford
D
esigned by sculptor Sir Anish Kapoor and engineer Cecil Balmond, the ArcelorMittal Orbit is one of the most striking and enduring visual legacies of the London 2012 Olympic
and Paralympic Games. It is the UK’s tallest sculpture and at the summit, offers a 360-degree view of London. The project involved replacing an inefficient chiller that had come to the end of its life with a Carrier AquaSnap 30RB 160R air-cooled liquid chiller, with scroll compressor, plus an added De-Superheater heat recovery option. The 30RB chiller also has refrigerant leak detector, compressor soft starter, super enviro- shield anti-corrosion protection, and water exchanger frost protection.
Carrier was commissioned by ParkServe, on behalf of London Legacy Development Corporation (LLDC), to undertake the project, and enlisted the support of local contractor L&B Technical Services to complete the challenging installation. Given the height and location of the ArcelorMittal Orbit’s roof plant area, at the top of the 114-metre-tall structure, securing a crane permit was costly and complicated. However, the only access to the roof plant room was through a 1m x 1m hatch. To overcome this challenge, Carrier’s service technicians recommended and performed a strip down and rebuild of the 30RB unit. The chiller was dismantled off-site, packed into a ‘kit-of-parts’, and then transported to the roof plant area through the narrow access hatch. The unit was then meticulously reassembled on-site, eliminating the need for a crane and
significantly reducing the overall cost. This method was not only cost-effective but also ensured that the chiller was installed without compromising the warranty, maintaining Carrier’s high standards of service. “This was a great project to work on. Squeezing a chiller through a 1m x 1m hatch isn’t something we do all that often,” said Rob Moffat contracts manager, L&B Technical Services Ltd. “The crane option was quoted for but, the cost for a Carrier strip and rebuild service was a fraction of the price. We are proud of our partnership with Carrier and this project exemplifies our abilities to deliver
complex and innovative HVAC solutions even under challenging circumstances.” “The project presented several logistical challenges, particularly with the limited access to the roof plant area, but Carrier’s innovative strip down and rebuild was the best approach,” said Hannah Barclay, head of contract management, London Legacy Development Corporation. “This new modern chiller not only helps meet the current climate control needs inside the ArcelorMittal Orbit but the addition of a heat recovery De- Superheater provides a sustainable solution for years to come.”
Comprehensive controls solutions for the Grand Palais venue
Distech Controls, a specialist in intelligent buildings, has installed its Eclyps Building Management System (BMS) at the Grand Palais, Paris, providing a comprehensive solution that addresses heating and cooling production as well as occupant comfort
A legendary building
An emblematic monument in the heart of Paris, the Grand Palais was built for the 1900 Universal Exhibition and has been a cultural centre ever since. Its 77,000 square foot of floor space regularly hosts a variety of exhibitions and fairs.
The Grand Palais underwent its first major
restoration since 1900 to host the fencing and taekwondo sporting events in its mythical Nave for the Paris 2024 Olympic and Paralympic Games. As part of the renovation, a number of Distech Controls solutions were installed to deploy a BMS and improve the monument’s environmental performance.
A BMS that provides exemplary environmental performance
The Eclypse solution from Distech Controls provides air treatment for the Grand Palais, in the Nave and adjoining galleries. The ECY-S1000 connected modular controllers are linked directly to a weather station, enabling a night-time free cooling system to be activated when conditions are right. In fact, as soon as the air outside is colder than inside, the Nave’s glazed windows open to let in outside air, ensuring natural cooling and air renewal, which in turn leads to significant energy savings. The Eclypse solution also includes ECY-S1000 connected modular controllers for cooling computer cabinets and distributing cold. The DC Space solution has also been deployed in the Grand Palais offices. This

multi-business management solution enables occupants to easily adjust their comfort settings (lighting and blinds) using Uniwave’s sleek Allure remote controls.
Finally, the Palais d’Antin, which is home to the Palais de la Découverte science museum, is also equipped with Distech Controls solutions, to guarantee the continuity of the BMS system throughout the Grand Palais building.
Involved in the construction and renovation of many of the buildings hosting the Paris 2024 Olympic and Paralympic Games, Distech Controls manufactured nearly 7,500 of its products in Canada and France to meet the needs of each venue and contribute to the environmental performance.
