What is SolarCool

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 ofthe 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.

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.

Where is the energy consumed on existing technology

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

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 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

Solar Assisted Systems

SolarCool increases the capacity of the compressor, utilizing the 100% renewable energy provided free by the sun.

Example COP’s

Assuming full load is required, all compressors will run.

The panel absorbs the UV radiance from the sun, creating free heat. Subsequently heating the refrigerant gas as it passes through the heat exchanger…

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…

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.

“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

“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 opportunity!” - Chief Engineering Contractor, Golden Harvest
