The first CIAT chiller project supplied by Amp Air has been successfully completed at the John Vane Science Centre, part of Queen Mary’s Charterhouse campus, near the Barbican in central London.
The high performance, high efficiency AquaCIAT 2 Evolution chiller was installed by Basildon-based Hawkes Refrigeration Engineers as part of a major replacement and upgrade of the building’s air conditioning system. It had previously relied on an ageing split system, using a water chiller linked to remote condensing units.
Toshiba distributor AMP was recently also appointed a distributor for CIAT following the global takeover of the France-based manufacturer by United Technologies, parent of Toshiba.
The packaged air-cooled CIAT chiller, with a capacity of 141kW of cooling, is equipped with optional inverter-controlled variable speed pumps for improved efficiency, delivering an EER of 3.09 and SEER of 4.06.
The R410A-based system running on Scroll compressors is designed to allow for future expansion as part of a staged replacement process. This includes the use of 6in diam chilled water pipework and a 10in low loss header to permit the addition of up to three further Toshiba/Ciat chillers, one of which would be on standby.Given the sensitive research environment, the chiller is equipped with enhanced acoustic insulation in order to minimise noise in the vicinity of the installation.
The chiller was craned onto its new galvanised steel framework base at ground level alongside the building, under the project management of Hawkes Refrigeration. Technical support staff from CIAT attended the commissioning and worked alongside engineers from Hawkes Refrigeration and Queen Mary College in the successful commissioning process.
Mark Parkin and Barry Hawkes, senior engineer and director of Hawkes Refrigeration who headed up the project, said: “This was the first CIAT chiller installation we have carried out. In discussion with the customer, we decided that as CIAT was now part of the Toshiba offering through AMP, we felt confident of the quality and technical support behind the product. Commissioning was relatively straightforward and we were pleased to have the technical support of CIAT and AMP staff on site.”
Ron Hodgson, building services project manager at Queen Mary College, said: “The project went extremely well and is now up and running trouble-free. We anticipate a mammoth return in terms of reduced running costs over the next few years.”
