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.

Inverter systems & Multistage systems

Cont…

Inverter systems 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. The facts are - the hotter it gets, the harder the system works Cont…

Staged compression systems 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. Again…the hotter it gets, the

How SolarCool saves so much energy

Cont…

Staged compression system, full load – no sun

Compressor SolarCool 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.

Condenser Expansion Valve Evaporator Next…

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 This process changes the kinetic energy of the gas molecules, forcing the molecules to move faster, thus enhancing the mass flow in the system Compressor SolarCool With sun… Yielding a reduced energy demand as the compressors begin to shut down and the panel takes over the load requirement Returning an increased capacity to the evaporator Condenser Evaporator Expansion Valve No other system on the planet offers this kind of efficiency Next…

Compressor SolarCool

Inverter systems

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.

Please note:

The next 3 slides are for the technical engineers whom have an understanding of the Ideal Gas Law. If you would like to skip this section, please

Cont…

p * V = n * R * T

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.

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

In a nutshell…

𝑛 Super Cooling – a higher mass flow 𝑚 = increases the capacity at the 𝑡 evaporator at 1 : 1. The formula for increase in capacity: 𝑄 = 𝐿 ∗ . So the first stage with SolarCool achieves a higher cooling capacity, making the second, third…compressors kick in much later. The time saved from the additional compressors multiplied by their power consumption = the savings.

The hotter the sun shines, the higher the mass flow increases and the higher the cooling capacity of the first stage gets. Subsequently less run time is required for the additional compressors to kick in and therefore more electricity consumption is saved.

Using the suns free energy, no other system on the planet offers this kind of efficiency Cont…

Very important

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):

Problem 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.

Proposal 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.

Benefits 1. Reduce electricity overhead 2. Improve overall working temperatures in the staff kitchen areas 3. Happy franchisee 4. Happy employees Cont…
