Carrier cools important art collection
Carrier Air Conditioning has had a comprehensive
involvement in satisfying the new air conditioning
requirements for the refurbishment and remodelling of
the Sainsbury Centre for Visual Arts, at the University
of East Anglia, Norwich. Six Carrier chillers of
different sizes, from the small 33 kW Aquasnaps to the
medium-sized 250 kW units, coupled with forty-five of
Carrier’s most advanced 39HQ modular air handling units,
have provided much of the solution to a change in
requirements from the original ‘seventies basic heating
and cooling specification.
Designed between 1974 and 1976 and opened in 1978, this
was Norman Foster’s first major public building. It is
iconic and quite massive with a vast multi-storey open
exhibition space for the main collection. Below this,
new galleries and lecture theatres have been added, and
the two elements of the Centre have additionally been
neatly bridged by a new gallery building and entrance
area.
The Sainsbury Collection is a very personal, ‘living’
collection that is still being added to, but it is also
a study collection with a University Department built
around it. It has its specialisms such as objects from
the cultures of the South Pacific, and also contains
famous works by Henry Moore, Francis Bacon and
Giacometti.
The buildings were designed for future extension.
However, the original air conditioning requirements only
envisaged providing far less stringent conditions for
the preservation of the collection and the comfort of
visitors and students than are expected today. The air
conditioning equipment also operated with refrigerants
that now need replacing with more environmentally
acceptable alternatives.
All of the new equipment has had to fit in with the
stringent new regulatory regime. The air handlers for
example comply with BS/EN 1886. These and the chillers
are Eurovent certified. Yet it all still had to fit into
the spaces occupied by the previous generation of
equipment.
Two of Carrier’s 30 series air-cooled chillers,
providing 244 kW of cooling each for the new gallery
extension that joins the two earlier buildings, had to
be fitted into the existing basement plant room. This
could only be accessed from beautifully landscaped lawns
below the building, and even then the equipment had to
be craned in through a grille space in pieces and
re-assembled within the room.
Additionally, two Aquasnap mini-chillers have been
provided to supply chilled water for the new Carrier
Holland Heating air handling units serving the School of
World Art Studies and Museology and the public
restaurant areas. These units had to be compact and slim
as the only place for them is close to the wall in a
loading bay used by large trucks. Clearance was vital.
The Carrier units are only 478 cms deep.
Upstairs in the main gallery the Carrier Holland Heating
air handling units have had to be fitted inside the 3
metre skin outer walling, replacing the more basic
original units – fortunately the latest 39HQ Holland
Heating units are modular. Air is delivered to the large
main gallery space via giant air nozzles in the original
Italian louver-blind system that covers the walls and
ceiling. Enormous volumes of air need to be moved by the
air handling plant as the space is vast. The total
building area is now well over 6000 square metres.
