The pioneering solution, developed
by Klima-Therm and Geoclima, was
crowned Air Conditioning Ancilary
of the Year 2017 at the ACR News
Awards, before an audience of several
hundred leading lights at the Chelsea
Harbour Hotel, London.
during the so-called “red band” times
that can currently cost up to 10 times the
nominal kWH charge.
This delivers significant savings, given
the typical 15-20 per cent reduction in
night time energy costs, with even greater
day-to-night disparity predicted with the
onset of smart metering. However, further
savings come from limiting peak power
demand on a site, using the batteries to
augment mains supply and renewable
inputs to keep peak power within a set
limit.
Teslamiser can also operate as an
uninterruptible power supply (UPS),
maintaining plant operation in the event
of a power cut for long enough to restore
normal operating conditions. In critical
applications, such as operating theatres
and data centres, this is not just a “nice to
have” but a “must have” capability.
Tim Mitchell, sales director of Klima-
Therm, says: “The key is to take a “total
energy approach”, which combines and
integrates advanced battery technology
with multiple renewable energy sources
and mains power, to optimise plant
performance and efficiency resulting
in lower running costs, reduced
environmental impact and more
comfortable and sustainable buildings.
“The ability to time-shift
electrical demand has a
double advantage, as it not
only reduces running costs
but also enables end users
to manage a site’s demand
profile in order to reduce
peak electrical draw. This
reduces exposure to punitive
peak demand energy tariffs.”
When a renewable
energy source, such as
a photovoltaic supply, is
available, Teslamiser can be set to charge
and store energy when supply is free in
the day and release it when supply is
reduced or unavailable, at night.
“Teslamiser adds significant extra
capabilities to the already highly
efficient Turbomiser and ultra-efficient
K-Turbo chillers. Its ability to time-
shift electrical demand, so reducing
running costs, coupled with its role as an
uninterruptible power supply, gives end
users an additional level of reassurance by
significantly improving resilience.
“It is a particularly attractive option on
Turbomiser and K-Turbo chillers because
the compressors
on these chillers
have a very low
starting current
(5A), and from then
on the current
draw is smooth
and steady up to
full load operation.
We believe this
combination
will be useful in
many situations,
particularly for
critical applications where continuity of
cooling is vital.”
The compact Teslamiser is available as
a bolt on module on Turbomiser and
K-Turbo chillers, as well as a standalone
system that can be retrofitted to existing
installations. It can be purchased outright,
and rental options are also being devised,
with ongoing savings from electricity
running costs effectively subsidising or
even fully financing the rental charges.
Mr Mitchell says: “Looking ahead, there
are exciting possibilities for extending
the capabilities of Teslamiser to include
intelligent energy recovery directly from
the chiller to charge the batteries. This
would create a genuine total energy
system that optimises power from all
sources – mains, renewable and self-
generated sources – for even greater
efficiency and savings.”
