Carrier, one of the world leaders in heating, air conditioning and refrigeration technology, has supplied three high-performance chillers for a ground source district cooling and heating scheme for Riverlight, an exciting new riverfront development in the heart of London.
The system delivers significant environmental benefits, including excellent energy efficiency, reduced carbon emissions, lower running costs as well as optimal comfort conditions for residents.
Riverlight, being developed by regeneration specialist St James, a member of the Berkeley Group, is located alongside the River Thames near Battersea. The district is composed of 812 residential apartments, including 116 shared ownership units, retail sites, restaurants, bars, leisure facilities and a child day-care centre.
Designed and installed by ground source system designer and installer IFTech Ltd., the environmentally sustainable scheme is believed to be the largest open loop ground source project of its kind in the UK.
The scheme comprises eight deep water wells linked to the chillers and heat pumps. Carrier supplied three AquaForce® 30XW HP 500kW chillers for installation by IFTech Ltd.
The Carrier chillers supply six multi-storey buildings with comfort cooling and hot water from a central plant room, linked to a series of boreholes. This enables the transfer of cooling and heating energy to and from aquifer groundwater, boosting efficiency and significantly reducing carbon emissions.
The Carrier AquaForce chillers were chosen because of their excellent efficiency and proven resilience, vital in such large-scale residential projects. The chillers are equipped with an enhanced control system, which optimises the system for production of hot water or chilled water. This in turn connects to and integrates with the site’s building management system (BMS), for even greater efficiency and control.
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.
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.”
In addition to the quality of the design, a key element in such schemes is the robustness and reliability of plant. John Foster, who headed up the project for Carrier, said: “With total reliance on the system for comfort cooling and hot water, the reliability of the equipment at the heart of the project is paramount. Downtime is simply not acceptable.
“The AquaForce chiller is known for its outstanding reliability, being based on Carrier’s proven high efficiency screw compressor, with thousands of installations worldwide. This provides the exceptional resilience required.”
He added: “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.”
The final phases of the Rivelight project were recently completed, and the developer has announced that all apartments have now been successfully let or sold.
