(American Ambassador's Official London Residence)
Fancoil Unit
|
Actionair Fan Coil Units
are helping to provide discreet airconditioned mcomfort for the
American Ambassador's official London residence. Standing in twelve
acres
of Regent's Park Winfield House is in the heart of London, but
could be deep in the country. At night the only sound to disturb
the silence
in the grounds is the occasional nocturnal cry from nearby London
Zoo. The thirty six-room house was built for Woolworth heiress
Barbara Hutton in 1936. Ten years later, at the end of World War
ll, she
offered the house to the US government for the token price of $1
on the condition that it be used as the official residence of the
American Ambassador to London. Recently a £7 million refurbishment
of the infrastructure and services at Winfield House has been carried
out, including complete new mechanical and electrical services
specified by Gifford and Partners of Oxford.
Architectural
cabinets Some forty Actionair Hydropac PVW Fan Coil Units designed
for waterside
control now provide heating and cooling for the Ambassador's quarters
and offices. The units, supplied in chassis form, are located within
architectural cabinets specially designed to integrate perfectly
with the many features of the house such as the fine furniture,
paintings and the exquisite green Chinese wallpaper in the Garden Room.
A rugged,
heavy-duty construction is an integral feature of the Actionair
Hydropac design. Fan coil chassis of 1.2mm galvanised steel and fan
decks
and back plates of 1.6mm ensure durability. Noise levels from each
Fan Coil Unit are contained to an absolute minimum by meticulous
balancing of impeller/motor assembly, resilient mounting of the
fans and insulation of the integral discharge plenum. Temperature control
of each Hydropac unit is by means of modulating 4 port diverting
valves
and actuators operated via BMS temperature controller
and
return air sensor. Fine adjustment Like all the latest Actionair
Fan Coil Units, Hydropac models offer the
unique feature of "fine adjustment" fan speed regulation,
which enables an accurate match of output to space requirements during
on-site commissioning. A 9-step transformer with pure sine wave control
in conjunction with a choice of three fan speeds provides a choice
of 27 different settings ensuring minimum energy consumption by matching
the precise system requirements in each location.
