Only the outdoor units and internal branch selector boxes were replaced when Space Air installed Daikin’s VRVQ system to upgrade from R407C to R410A.

The offices of Daikin distributor Space Airconditioning in Guildford is claimed to be the first project to install a Daikin VRVQ system to replace a Daikin R407C VRV system without having to replace the interconnecting pipework and ceiling cassette fan-coil units. Only the outdoor units and internal branch selector boxes were replaced. VRVQ can also replace R22 systems without having to replace pipework.

Space Air ensured that the first VRVQ system available to the UK was earmarked to replace a VRV K Series R407C system. The company’s technical after-sales manager Sibat Butt, said, ‘It is quite usual for new Daikin equipment to be installed in our own premises, but normally it would be destined for our training suite or a showroom. On this occasion, we chose to replace the system serving our main offices as the energy-efficiency advantages satisfied one of our planned ISO 14001 objectives.

‘The project was completed over a weekend, and the only impact on the office staff was the temporary imposition of a few ceiling tiles being removed on Friday afternoon. By Monday morning, the new VRVQ system had been fully commissioned and was up and running, many staff being none the wiser that any change had taken place.’

The VRVQ system, available from Space Air, affords all the operating and energy-efficiency benefits of a completely new installation, at a fraction of the cost. Installation can be phased for added convenience, and increased capacity can be achieved where required.
