11. Prerequisite understanding - Compression & Absorption
In1926, Albert Einstein and one of his then top students
Leo Szilard, invented the first fully functional refrigerator
- using the absorption process.
SolarCool is in essence a
more modern day version of
the Einstein–Szilard
refrigeration process. The
main difference being that we
are partnering the modern day compression cycle with the
absorption process. In the absorption cycle, heating the refrigerant
was generally achieved by burning a fuel (oil or gas), in contrast we
use the free energy provided by the sun to heat the refrigerant, in
essence taking over the workload of the compressor and therefore
substantially reducing the energy consumed.

Absorption Refrigeration
12. What is Solar Refrigeration?
• A thermodynamic collection system
What it is not…
• …Solar PV
13. Example:
Testing in pure like for like environment conditions, in order to reproduce
the average energy saved on a standard commercial 30kW (cooling
capacity) refrigeration system using Solar technology - would require an
average of between 30 & 40 250w Solar PV panels.

14. Where is the energy
consumed on existing
technology
15. The facts are, regardless of the compressor in
use…
•…DC Inverter
•Super DC Inverter
•Hyper DC Inverter
•Staged Compression
•Digital Scroll…
…in general c. 80% of the energy on all systems
is consumed by the compressor alone.
Compressor energy consumption
17. The general engineering make up the system is designed to
produce fluctuating loads, subject to the systems requirement.
Therefore when the load requirement is low, the compressor will
logically run at low speed.
Subsequently, when the ambient temperature
increases and therefore load requirement is high, the
system increases its load capacity, therefore
substantially increasing the energy consumption of
the compressor.
Inverter & digital scroll systems
The hotter it gets, the harder this system works
18. When the load requirement is low, the stage system is
designed to run on reduced compressor numbers (i.e.
single stage), commanding additional stages as the
load requires.
Therefore as with fluctuating load systems, the
hotter it gets, the load requirement from the
system increases. In the case of multistage
compression, additional compressors enter the
phased platform to satisfy load demand.
Staged compression systems
Again, the hotter it gets, the less efficient the system becomes
19. Solar Assisted Systems
SolarCool increases the capacity of the compressor, utilizing the 100% renewable energy
provided free by the sun.

25. The panel absorbs the UV radiance from
the sun, creating free heat. Subsequently
heating the refrigerant gas as it passes
through the heat exchanger…
26. At this point, we now have a distinct change in
the physics of the thermal energy.
Raising the internal energy within the solar
collector
A higher value of kinetic energy within the gas
molecules
Intermolecular forces weaken, and the molecules
space out
The molecules now move with a higher velocity
All resulting in an increased volume flow…
27. Finally, this results in a reduced
energy demand as the compressors
begin to shut down as the sun
takes over the load requirement
Due to the increase in molecular velocity, most,
if not all of the pressure produced from the
additional heat is released in mass volume flow
and subsequent volume conversion within the
condenser and expansion valve.
REMOVING THE HEAT
We now have a hugely increased DeltaT. This combined
with the increased kinetic energy of the gas molecules,
effectively increases the surface area of the condenser.

the power of the machine starts a surprising decline, and remains there
throughout the day’s hottest phase.” - Chief Engineer -Pizza Hut

“After retrofitting seven of our sites, they
collectively reduced the energy
consumption by 36%, therefore they were
clearly the right partner for this new build
project. So far they are producing results
that are in line with their own projections
and therefore well in line with our
expectations”. Richard Cox, MD

The largest fresh bread manufacturer in Malta, boasting a wealth of high profile
customers. As with most businesses in the sector, this facility consumes a vast amount
of electricity on a number of applications including process cooling, freezing,
refrigeration and comfort cooling throughout.
“I have to be honest, I was personally sceptical about
the projected abilities of SolarCool when first presented
to me. However my son was completely the opposite,
and convinced talked me
with the testing. I am now
very pleased he did, as we
could have walked away
from a fantastic

August test data – the 220kW 5-stage process cooling plants kWh usage data was tracked for the
whole month of August 2014 using the well respected RDM system.
September data – using the same system, the kWh consumption was then tracked for the
whole month of September – post SolarCool installation
The bars above represent the average daily usage, starting with Monday on the left. In comparison to
August usage, in total SolarCool reduced the energy consumption by 37%.

Although we retrofit Solar thermal onto many different systems…our own systems are Engineered and..
Originating from the USA, then subsequently further development and patent protection pending internationally in regards to advancements into heating, refrigeration & chillers.
And these are just some of our customers, some we have been working with for a few years, others are relatively new due to the advancement into refrigeration.
As a business we now operate across 5-separate continents.
Firstly let go back to 1926….
There is clearly a vast difference between the two, as well as huge space benefits, the most important being return on investment
To give you an understsanding of the cost vs. return on investment implications…
To understand where the energy efficiencies on our system are derived from, first we need to understand where all the energy in consumed now.
There are three main types of compressor used throughout the USA…
When the load requirement is low, the system will run at low speed. As low as 30% of its capacity
In this particular case 33% of the systems total capacity
