Option Five:
ECO-SS Energy Conversion Optimizer
Smart start and power supply
management unit
Why and How: Refrigeration
systems consume electrical energy (power supply) converting it into thermal
energy. (to make your cabinet cold)
There are two distinct groups
of electrical power available to supply your fridge system:
(A) Abundant Power (Mode A) is whenever a 110 or 240 volt AC
mains or generated supply is available OR when the 12V DC power
supply
is fed from an alternator, solar, etc. and the voltage exceeds 13.5V. (Excess
power after the batteries are topped up, energy that would
otherwise be
wasted)
(B) Limited Power (Mode L) is when a power supply is from
a battery source only.
The ECO-SS system is a unique
Ozefridge device that reduces battery demand by operation as follows:
1.) Whenever power
supply is abundant, (Mode A), the ECO-SS automatically triggers the system's
controller into run mode, starting the ozefridge
system, forcing it to consume, convert and store the abundant electrical
energy into the eutectic tank as thermal energy for future use.
2.) When engaged, the
ECO-SS also operates the ozefridge system at maximum compressor speed to
provide the most refrigeration into eutectic
storage while the power supply is abundant.
3.) When ECO-SS takes
control, the eutectic mass is maintained in a frozen state within the lower
temperature parameters of the 'Sure-Thaw"
controller's settings.
4.) During normal operations,
the ECO-SS checks constantly for the availability of abundant power. this
ensures that any abundant power is always
detected and utilized.
5.) Whenever only limited
power (Mode L) is available, the frozen eutectic mass will hold-over the
cabinet temperature for up to a day or so and if no
further
opportunity to use abundant power occurs in the meantime, the system
automatically reverts to using the limited power supply as further
refrigeration is required.
Examples of how this
exclusive Ozefridge option can spare your batteries:
Example 1: Bill
sails his yacht mostly at weekends and when at sea battery power is at a
premium. During the week, Bill's yacht is in the pen connected to 240 volts
mains power so he leaves everything in the fridge and it runs automatically
on the mains ready for the next outing. While bill runs a small gen-set at
night for an hour or so and on occasions he is under motor.
Outcomes with a basic aluminum cold plate system:
If Bill
installs an air-cooled cyclic cold plate system, his fridge will run on
average say 10 minutes on and 20 minutes off. Without the backup of
water
cooling, the run times will increase and efficiency will decrease as
temperature rises during the hotter months. (Just when I needed you
most!). This type of
cyclic refrigeration requires power on demand throughout the 24-hour relying
mostly on the batteries limited power supply and
using little of any
abundant power when available. This is the most inefficient system with the
greatest demand on batteries).
Outcomes with
Ozefridge Eutectic System:
If Bill installs an
Ozefridge eutectic system with air and water cooling, 12/24 Volt & 110/240
AC operation and the ECO-SS option, he will enjoy
all the
benefits of eutectic refrigeration and have the most comprehensive power
management, control, and failsafe system available.
When Bill
sails out from the pen, his eutectic tank will be frozen solid with no
further refrigeration needed until the eutectic mass is consumed.
Now at
sea, the solar panel has topped up the battery yet there is still plenty of
sun and therefore abundant energy available. As the battery volts
exceeds
13.5 volts, the ECO-SS will cause the ozefridge to run and store more energy
in the eutectic tank. Later at night Bill runs the 240 volt
generator
for an hour or so and again the ECO-SS trips in and unlike other systems
will choose to run direct from the gen-set's 240 volts leaving
any charge
into the battery to be a net again.
With the
ozefridge ECO-SS power management and STC control; this system would require
little if any power from the limited battery supply.
Example 2: Fred is
cruising and relies on solar and a Honda 1KVA generator to recharge his
battery bank.
Outcomes with the
ozefridge eutectic system:
Fred has found that his
refrigeration is cold enough if his Ozefridge eutectic system has one freeze
per day involving about 4 hours of total
running
during the 24 hour period. Often Fred's batteries are fully charged yet
there is still plenty of wind or solar power, power that would
otherwise
be wasted, but the ECO-SS is causing the ozefridge to store this as thermal
energy. at night, if gen-set is used, the Ozefridge will be
at it
again, storing energy (refrigeration in advance) and sparing precious
battery supply. Fred's system rarely uses power from his battery supply
and when
in the marina the Ozefridge will run on the mains power from any country.
Whenever a 110 or 240 VAC supply is available, the system
automatically runs from the highest voltage available.

At Ozefridge Industries
Pty. Ltd. we manufacture multi-voltage eutectic refrigeration
systems to a build quality and performance unequalled by any
other. We include features either optional or unavailable from
others yet our prices are much lower than any similarly equipped
systems. Compare apples with apples and you will agree.
Why? Because we
manufacture here in Australia and distribute direct to you, our
customer. See report by
Fishing and Boating magazine
This direct relationship
allows pre-purchase discussions giving Ozefridge the opportunity to
verify the suitability and if needed to adjust the package to meet
your specific requirements.
