If you use Air-Conditioning to cool
your building you could be wasting up to 30% of
all the energy it consumes!
When switched on, typical air
conditioning systems operate continuously until
the room thermostat senses the desired temperature
and turns the system off. As the room warms up,
the thermostat switches the air conditioner back
on and the cycle repeats.
Air conditioning systems are usually
dimensioned to cope with the extreme cooling
demands of the few hottest days of the year (plus
a safety margin). However, in most operational
conditions, this maximum output is not required
and the system is oversized. So running the system
continuously until the room thermostat switches it
off means that the system operates with excess
capacity most of the time.
A typical cooling cycle with excess
capacity looks like this:
-
When
the cycle starts, the compressor pushes cooling
energy into the heat exchanger which acts as an
energy storage. At this stage, the system works
with high efficiency because compressors operate
most efficiently when fully loaded.
-
In
normal weather conditions, the energy storage is
soon fully "charged up". From this point
onwards, the compressor provides more cooling
energy than the heat exchanger can take - we
call this 'thermodynamic saturation'.
-
Running
the compressor beyond this stage does not
increase the cooling effect any more. It's just
a waste of energy!
This is where an ACES cuts in. Its
sensor-driven software algorithms are designed to
detect thermodynamic saturation and to optimize
the compressor accordingly. When overcapacity is
detected, ACES switches the compressor off and
avoids inefficient overcooling.
When ACES switches into "saver mode", the fan keeps running and your
system makes maximum use of the stored cooling
energy in the heat exchanger. Once the stored
energy is used up, the compressor can work
efficiently again and is switched back on. The set
room temperature is reached without the
inefficient parts of the cooling cycle. This
results in energy savings of up to 30% without
compromising cooling comfort.
