8. What SolarCool is…and what it is not

9. What is SolarCool? 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. SolarCool is not… …Solar PV. SolarCool 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.

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

11. Where is the energy consumed on standard system?

12. 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.

13. Inverter, Digital Scroll & Multistage systems

14. 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

15. 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

16. SolarCool systems SolarCool substantially reduces energy consumption by increasing the capacity of the compressor, utilizing the 100% renewable energy provided free by the sun. = + + = The fact is, the hotter it gets, the more efficient SolarCool becomes Inverter Systems Staged Systems

25. How we save so much energy

26. Next… Evaporator Compressor Condenser Staged Compression System in normal run process Assuming full load requirement, all compressors will run. Expansion Valve

27. Evaporator Expansion Valve Compressor SolarCool Condenser The panel absorbs the UV radiance from the sun. The vacuum tubes become internally hot and therefore heat the refrigerant gas as it passes through Staged Compression System with SolarCool

28. 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…

29. Evaporator Compressor Solar Collector Condenser Yielding a reduced energy demand as the compressors begin to shut down as the sun takes over the load requirement Most…if not all of the pressure produced from the additional heat is released in mass volume flow and therefore substantially increased molecular velocity Staged Compression Expansion Valve Thereafter Increasing the ΔT between condensing and ambient temperatures, effectively increasing the surface area of the condenser System with Solar Collection

30. Those who may be concerned how the condenser addresses any additional heat generated by SolarCool: 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), SolarCool 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 SolarCool to easily cope with any additional heat, as is shown here and further clarified in third party testing data (T after condenser): Very important 10kW system without SolarCool T-discharge T-after condenser 10kW system with SolarCool T-after panel T-discharge T-after condenser

A clear cut case of ‘the hotter it gets’ the less the SolarCool system works’ – and as importantly the more the comparison A+ system works.

34. What our customers say

35. “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%

36. “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 (Fuel/Gas Station Retailer) 6-months test results 63% - - Car show rooms 51% ( Robert Williams, Vice President of Engineering)
