There are two systems, a 28 kW SMMS and a 33.5 kW SHRM. The ability of these VRF systems to have both 3-pipe and 2-pipe systems operating through a single central controller was a major attraction to WNT.
The systems were installed in an industrial unit next door to create an open-plan call centre for WNT’s distribution service for spares and supplies by Toshiba accredited installer Elyo UK. The work has benefited from the tax advantages of Enhanced Capital Allowances.
The south-facing units have glazed frontages, and the existing office areas were unbearably hot last summer.
Changes include the creation of a mezzanine office area above its warehouse and the new call centre
The mezzanine offices are served by the 3-pipe system, so that individual offices can have either heating or cooling at the same time. The call centre has additional heat gain from the computer equipment, so it requires only a 2-pipe system.
WNT operates fixed hours, so time-clock control is adequate.
