Such has been the growth in VRF air conditioning in the UK that it is now the second largest sector in this market. Recent figures from BSRIA value the VRF market at £87 million a year — about 17% of the market. In achieving that second place, VRF has overtaken chillers in value terms and is also making ground on the traditional commercial split sector.
To aid installation on site of Daikin VRV-II air conditioning equipment providing 975 kW of cooling for refurbishing a 1960s building in London, distributor Space Airconditioning supplied a range of extra services.
A programmable logic controller for Mitsubishi Electric’s City Multi air-conditioning range allows easy automatic interlocking, with multiple units controlled through card-key readers, passive infra-red devices, window contacts and over-ride switches. This PLC system links to the G50 and baby G50 controllers and is designed for applications such as hotels where it has been difficult to accurately control individual units in each room because of the localised setting of each guest.
The pressures placed on the cricket teams in the final match of the Ashes series at the Oval this summer were reflected in the demands placed on the air-conditioning system for the new £25 million OCS stand.
VRF unit
Toshiba’s latest VRF range is a 3-pipe heat-recovery system. The SHRM2 series offers 22 to 84 kW of cooling from a single inverter-driven system and up to 95 kW of heating. R410A is the refrigerant.
Tulip Hotel
The popularity of Daikin’s VRV air conditioning in hotels is reflected by the installation in the Tulip Inn at North Harbour, Portsmouth. Golden Tulip Hotels are regarded as superior-quality establishments. This hotel has 108 guest rooms on five floors, complemented by quiet lounge areas, stylish and contemporary restaurant and bars, three well equipped meeting rooms and a spacious reception.

Lighting the workplace well

15 October, 2005
HARRY BARNITT argues that following standard lighting guidance results in poor installations. One of the main reasons is the failure to put any light on the ceiling.
NEIL JONES describes how lighting control can cut an organisation’s fuel bill and also deliver other key business benefits.
Plug-and play-connectivity has changed installation practices for lighting, so that projects can be speeded up up enormously, as MARK REDFERN explains.
Bailey and Green
Developing off-site manufacture is a vital element in the future development of contractor NG Bailey, and it brings major benefits to the construction industry — as CAL BAILEY and PHIL GREEN explained to Ken Sharpe
Rick Plummer looks at the not-so-obvious costs that can scupper the most carefully planned budget for heating plant and explains how to avoid them.
Manufacturing plant rooms off site offers a range of benefits, which are increasing all the time — as STEVE COOPER explains.
Installation time for services for a new office development for British Sky Broadcasting has been halved by using building-services modules designed by MEP Solutions and made off site. The prefabricated modules connect some 60 to 70% of the services on each floor. The rest are piped in the traditional method because of structural considerations and layout.
Cable tray
Cablofil wire-mesh cable trays are being used in modular pre-fabricated services units for Manchester Royal Infirmary, or the Manchester Joint Hospital as it is known.
Pump set
Armstrong Holden Brooke Pullen now offers configurable HVAC pumping packages that reduce installation time on site and enable designers to select an effective system solution without the high costs and longer lead times associated with bespoke systems.
