Where is most of the systems energy consumed? The facts are regardless of whichever system is in place… …DC Inverter Super DC Inverter Hyper DC Inverter Staged Compression Digital Scroll… …c. 80% of the energy on all systems is consumed by the compressor alone.
The general engineering make up of the inverter 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 inverter system increases its load capacity, therefore substantially increasing the energy consumption of the compressor. Inverter systems The facts are - the hotter it gets, the harder the system works
Cont… 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 the Inverter system, 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 requirements. Staged compression systems Again…the hotter it gets, the less efficient the system becomes
Next… SolarCool systems SolarCool substantially reduces energy consumption by increasing the capacity of the compressor, utilizing the 100% renewable energy provided free by the sun. = + + = Fact…the hotter it gets, the more efficient our system becomes Yes…more efficient Inverter Systems Staged Systems
Next… Evaporator Compressor SolarCool Condenser Expansion Valve Staged compression system, full load – no sun The refrigerant will run through the panel at normal flow rates and continue the standard refrigerant process. At full load requirement all compressors will run.
Next… 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 Yielding a reduced energy demand as the compressors begin to shut down and the panel takes over the load requirement No other system on the planet offers this kind of efficiency This process changes the kinetic energy of the gas molecules, forcing the molecules to move faster, thus enhancing the mass flow in the system Returning an increased capacity to the evaporator With sun…
Next… Evaporator Expansion Valve Compressor SolarCool Condenser The process works in the same way with variable and inverter systems. The simple difference being that the compressor slows down as the sun takes over the workload. No other system on the planet offers this kind of efficiency With sun… Inverter systems

Absorption of the UV irradiance in the panel, heats up the refrigerant. The important part of this process is the irradiance, not the ambient temperature. Cont… p * V = n * R * T - Heat - Gas T V p * V = n * R * T P n As the refrigerant is in a continuous gaseous state, the Ideal Gas Law applies. The law applies to many different types of application. In the case of SolarCool it's the mass flow making the difference = amount (n) of gas molecules per second. p, n, R constant Volume increases V, n, R constant pressure increases p, V, R constant n decreases Gas heated
In a nutshell… Cont… Using the suns free energy, no other system on the planet offers this kind of efficiency
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. Of course it would be fantastic to achieve the additional efficiency without additional heat, but the additional heat is the price we pay in return for the higher efficiency. We actually want the heat from the solar panel, enhancing the capacity of the compressor; with zero negative impact on the rest of the system. Enthalpy is increased by a maximum of 10%, which again we obviously would prefer not to have, however all modern systems are well able to cope, and subsequently return a much better efficiency for the heat: 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 dimensions for the compressor, condenser and all other parts. Additionally, the condenser is typically designed with a 5-10% safety margin above the compressor’s capabilities. This margin and the facts covered in the first 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): Next… 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.

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%

The energy balance shows that with the addition of suns UV rays to the process, the energy consumed from the power supply is significantly reduced” - Francisco Javier Vadillo – Pizza Hut Problem Proposal Benefits The existing comfort cooling systems are simply not achieving comfort. This is mainly due to the ambient temperatures throughout the day, therefore the system virtually never achieves an acceptable working environment temperature of below 82°F. Not not only consuming high levels of energy, but also failing to maintain an acceptable temperature for staff in high turnover food preparation areas. Replace the existing 10-ton system with the Solarcool equivalent 10-ton system. Used for comfort cooling - with a target temperature of below 77°F. 1.Reduce electricity overhead 2.Improve overall working temperatures in the staff kitchen areas 3.Happy franchisee 4.Happy employees
Substituting the existing kitchen 10-ton system, along with the 2 x 5-tons systems situated in the restaurant. The installation took place on September 24th 2012. Thereafter a monitoring energy circuit marker recording before and after the installation. This device served as a witness to the results.

Next… “When the sun is in the sky, the compressor in these machines basically acts as a pump, moving the refrigerant throughout the components, in our view these systems are optimal in this type of application over any other” - Francisco Javier Vadillo – Pizza Hut Existing vs. SolarCool Prior to installation the kitchen was running at 82°F, now operating at a significantly more comfortable temperature of 74°F to 75°F. Oscillation is observed at a downward trend, representing a stable thermal load management around the expected temperature.
