Klima-Therm and sister company LH have delivered a bespoke chiller solution for John Lewis at its Peter Jones shop in Sloane Square, London, marking a world-first for manufacturer Rhoss.
The 2MW cooling capacity installation is powered by magnetic-levitating Turbocor compressors, the first time Rhoss has supplied its home-grown design of Turbocor-based chiller anywhere in the world.
Klima-Therm’s solution required a specially designed low-height chiller mounting system, and compact low-profile chillers, each 9350mm in length and based on three Turbocor compressors arranged in two refrigerant circuits.
The project was delivered on a tight timescale, to enable continuity of cooling and minimise disruption to the building. The existing chillers were removed and the new units lifted in place over a weekend, with full installation and commissioning completed within a week.
Tim Mitchell, Klima-Therm director, said: “The project required close collaboration between the client, consultant, contractor and supplier teams. After a site survey, we carried out a detailed component-level design process to ensure the requirements for size, noise, energy efficiency and weight could be delivered.
“The result is a high efficiency, low noise bespoke solution that fits the tight constraints on the site, and will significantly reduce the client’s cooling energy bills over the anticipated 15-20 year operational life of the equipment.”
Klima-Therm is remotely monitoring the performance of the chillers, to ensure operation is optimised for energy consumption and occupant comfort.
The company has worked with John Lewis for many years, providing high performance cooling and HVAC solutions for retail outlets and administration buildings across its UK estate.
