Three high-performance Carrier AquaForce® 30XW HP 500kW chillers were selected for a ground source district cooling and heating project for Riverlight, a prestigious new development alongside the River Thames in the heart of London.
Customer: IFTECH LTD
Location: London, UK
Project Completed: June 2015
The district cooling and heating system serves a development of six multi-storey buildings, comprising 812 residential apartments, including 116 shared ownership units, retail sites, restaurants, bars, leisure facilities and a child day-care centre. Carrier chillers provide both heating and cooling, linked to a series of deep boreholes enabling energy storage and recovery via a heat exchange system. The environmentally sustainable scheme is believed to be the largest open loop ground source project of its kind in the UK.
Riverlight is a development of six multi-storey buildings undertaken by regeneration specialist St James, a member of the Berkeley Group, located alongside the River Thames near Battersea in London. The development is served by a centralised district cooling and heating system, designed and installed by ground source specialist IFTech Ltd, which makes use of deep well boreholes to store and recovery energy. Carrier AquaForce chillers were chosen because of their excellent efficiency and proven resilience, vital in such large-scale residential projects. The chillers operate in three modes:
Use of three operating modes ensures that performance and efficiency is optimised across the chillers’ range, and comfort conditions are maximised for building occupants. The final phases of the Rivelight project were completed in mid-2015, and the developer has announced that all apartments have now been successfully let or sold.
The project presented a number of specific challenges:
Nick Boid, managing director of IFTech Ltd, said: ‘‘Riverlight is a very important project for us, and we are proud that it is the largest open loop ground source system in the UK. It demonstrates the practical and environmental benefits of the approach, in terms of improved energy efficiency, lower carbon emissions, reduced running costs and improved indoor comfort for those living there.”
John Foster, who headed up the project for Carrier, said: “It is the first district heating and cooling scheme Carrier has been involved with in the UK. However, given the demand to reduce energy use and cut carbon emissions, plus the drive to build new homes in city centres, we are keen to participate in pushing forward the boundaries of technology in this promising area in the future.”
