 | Audiences at the M&S Bank Arena in Liverpool are being kept comfortable by 46 e-Series modular chillers from Mitsubishi Electric. |
In December 2017 the arena’s car park, where the previous chillers were housed, was hit by a fire and the new solution needed to be installed in the limited space on and around the arena itself. The final design sees 11 90kW units installed on each of the four roof plant decks and two chillers installed on a gantry within the loading bay.
The design for The ACC Liverpool Group’s systems was undertaken by Redworth Associates, taking advantage of the modular nature of the e-Series which allows for up to six units to be connected in a design which best fits any given space. With a capacity ranging from 90kW to 1,080kW, they can provide space savings of up to 35% compared to traditional chillers.
During the installation, the Arena benefitted from e-Series units being available for next day delivery, rather than with the usual 8-10 week lead time which is commonly required for traditional chillers, enabling the venue to reduce the costs associated with the hire of temporary cooling. The units were installed during the winter months when cooling requirements were less in demand.
Adam Williams, senior project manager from ENGIE, The ACC Liverpool Group’s FM service provider, said: “The support from Mitsubishi Electric in making available 46 modules to meet our key programme requirements was unprecedented.”
With two inverter-driven compressors per module, the chillers have a wide operating range of between 8%-100% capacity, offering exceptional part-load efficiencies. As this range is where most chiller systems will operate for most of the time, this capability provides significant real-life efficiency savings.
