Jaguar Land Rover selects e-series chillers
A
n ew Mitsubishi Electric e-series chiller system has been chosen for Jaguar Land Rover’s principal design facility in
Worcestershire.
The new system was brought in as part of a major refurbishment project, with the overriding a im of improving the energy efficiency of the old system.
Chiller systems have been used to deliver controlled cooling to buildings for decades, but with an increasing focus on energy efficiency and running costs, Mitsubishi Electric developed i ts e-series modular chiller to provide a low- carbon, cost-effective option. Its unique modular approach allows up to six individual units to be connected, providing a system c apacity from 90-540kW. This approach reduces space requirements and simplifies lifting and installation.
Mel Baynham at Jaguar Land Rover explained t hat the Mitsubishi Electric system was the clear f rontrunner for several reasons: “We looked at a number of chillers, but the Mitsubishi Electric s ystem met all of our requirements including next day delivery.”
The system comprises two inverter driven compressors that allow it to operate between 8-100% of capacity.
“ We pushed for modular due to the fact that i f a unit went down we would be able to keep the system running while that module was being repaired. It also needed to be a highly efficient system capable of looking after a design office containing 2,000 people”, added Mel Baynham. T he new, fully operational system ultimately provides a more comfortable working
e nvironment for its 2,000 members of staff in its Research and Design building; a critical
factor for ensuring productivity. By having a b road operating range, advanced inverters and sophisticated controls, the e-series can deliver exceptional part-load efficiencies, which is where it will primarily operate. The balance of comfort and cooling performance will allow the car manufacturer to focus its efforts on refining automotive technologies at a significantly reduce d energy cost.
Jaguar Land Rover’s new cooling system was designed by Norvent Pipework and the installatio n was carried out by IDS Electrical. The system consists of eight EACV-P900YA-N e-series c ooling-only chillers, plus eight MELCOBEMS M INI interfaces, which provide individual indoor unit connections to a third-party Trend Controls Building Energy Management Systems (BEMS) via RS485 by either Modbus RTU or BACnet from a common platform.
