What SolarChill is…and what it is not

What is SolarChill? • A thermodynamic collection system driven free by the

Sun’s thermal energy. Achieving efficiencies of up to 70% on both inverter and multistage fixed speed compression systems, covering both Refrigeration and Air Conditioning (heating & cooling).

• The only renewable energy technology with a return on investment as low as a matter of months.

SolarChill is not…• …Solar PV. SolarChill requires minimal space and

investment in comparison to Solar PV, and is a considerably more advanced technology in the art of reducing both on and off grid energy usage via renewable sources.

Testing in pure like for like environment conditions, in order to reproduce the average energy saved on a standard commercial 30kW refrigeration system using SolarChill technology - would require an average of 13 Solar PV panels.

Where is the energy consumed on standard system?

Compressor energy consumption

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.

Inverter, Digital Scroll & Multistage systems

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 fact is - the hotter it gets, the harder this system works

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

SolarChill systems

SolarChill substantially reduces energy consumption by increasing the capacity of the compressor, utilizing the 100% renewable energy provided free by the sun.

So, what is the efficiency secret?

It’s all about the sun…

At this point, we have a distinct change in thermal energy. This in turn raises the internal energy (the sum of all microscopic kinetic and potential energy of the molecules), and the molecules start to move with a higher value of kinetic energy, which simply implies each molecule moves with a higher velocity than before.

As the molecules collide with one another they rebound with higher energies, moreover intermolecular forces weaken and the molecules space out further which results in an increase volume flow…

System with Solar Collection

Those who may be concerned how the condenser addresses any additional heat generated by SolarChill:

First and foremost, the systems condenser is designed to manage the compressors running at full load. The reality is when the sun is in the sky (the time when most systems run at full load), SolarChill will ensure that all compressors virtually never run at full load.

We actually want the heat from the solar panel, utilising the heat (temperature not pressure) we increase the gas molecules kinetic energy, hence increasing the mass volume flow, and additionally creating an improved Delta T therefore enhancing the efficiency of the heat exchanger (condenser).

All Refrigeration and A/C systems are manufactured to a very specific design point, e.g. for A/C systems ISO 5151. This point sets the capacities for the compressor, condenser and all other parts. The facts covered in the second paragraph above allows SolarChill to easily cope with any additional heat, as is shown here and further clarified in third party testing data (T after condenser):

What our customers say

“This technology incorporates a new and exciting element to the thermodynamic energy process. The energy balance shows that with the addition of sun’s UV rays to the process, the energy consumed from the power supply is significantly reduced.” - Francisco Javier Vadillo - Pizza Hut

- Process cooling 33%

- Convenience stores 58%

“At the time the ambient temperature begins to warm-up around 8:00 am, the power of the machine starts a surprising decline into a 6KW position, and remaining there throughout the day’s hottest phase.” -

Chief Engineer -Pizza Hut

“Having collectively reduced the energy usage in seven of our sites by an average in-excess of 36%, they were clearly the right partner for this project. So far they are producing results that are inline with their own projections and therefore well in line with our expectations.” - Richard Cox, Managing Director - The Kay Group (UK Gas Station Retailer)

6-months test results 63% -

- Car show rooms 51%
