Core of SolarCool is the solar thermal collector : 1 collector fits all sizes up to 35 kW ‐ in vacuum tube‐technology and highly effective also at lower sun radiance and clouds


• Dimensions: 1,6 x 1,6 x 0,13 m ‐ 61kg

• 20 Glass vacuum tubes with inner copper pipes

• One collector per one compressor

• One collector for up to 20 kW cooling capacity of a compressor

• U type collector, meaning the refrigerant flows through the copper pipes in the glass tube

• Fully assembled in one piece, high pressure and temperature resistant

• Insensitive against clouds and perfect fpr diffuse lights

The solar collector comes separately with the outdoor unit. They are connected on the spot by the installer

All rights reserved

SolarCool VRF System

• Separate outdoor unit• Spearate solar collector

(1 collector per compressor, max 17 kW = 5 Rtons)

• The collector comes premounted in one piece to ensure absolute pressure tightness and allo fast installation

• Both are connected on the spot by the installer

• This requires trained, skilled and certified installers with the appropriate equipment

SolarCool takes advantage of the new controlled systems with variable mass flows


"Old technology" ‐uncontrolled compressors

"New technology" ‐controlled compressors

• The air conditioners modulate their cooling capacity constantly according to the requirement and actual operation status

• The modulation happens mainly through a changed mass flow created by a compressor with a variable output

• A solar collector after the compressor impacts the mass flow and yields via the ideal gas law a positive impact on the compressor's consumption

• Compressors run with only one speed

• Units switch off, when target temperature was achieved

• Units work in one working point with maximum power

• An additional heating of the refrigerant after the compressor yields no impact

SolarCool explained for a car with tail wind


• Uncontrolled “systems”: If you have an engine which runs only 100 km/h and nothing more or less (of course this sounds ridiculous, because all cars have gear boxes and engines with variable speeds, but let’s imagine that the car has only one speed, because that is what compressors of on‐off units do), you have the potential to push the car to a speed of 130 km/h. But in reality you can’t because tires and brakes don’t allow it. So you had the potential, but you are not able to realize it.

• Controlled “systems”: If you have an engine with variable speed, then you could take your foot off the gas pedal, because the engine now with 70 km/h plus the tail wind of 30 km/h sum up to a total speed of 100 km/h and you are back at the original speed. Of course you would now save a lot of gas, because the tail wind is pushing you for free.

• And that is exactly what SolarCool does. We use an engine = compressor, which may slow down, but in the end with the booster from the solar collector achieves the original speed, or for air conditioners the cooling capacity.

30 + = ?

• Imagine you have a car which runs along with a speed of 100 km/h. It may not run faster, because the tires and brakes don’t allow that.

• Now while running it, you experience a very strong tail wind of 30 km/h. This would push the car to 130 km/h depending on the engine you have:

SolarCool

Condenser

The collector absorbs the UV radiance from the sun. The vacuum tubes become internally hot and therefore heat the refrigerant gas as it passes through

Enhanced capacity, yielding a reduced energy demand by the compressor

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

Ideal gas law as foundation of SolarCool: p * V = n * R * TAbsorption of the UV irradiance in the collector heats up the refrigerant. It is the irradiance which counts, not the ambient temperature.Absorption of the UV irradiance in the collector heats up the refrigerant. It is the irradiance which counts, not the ambient temperature.The refrigerant is in gaseous state, so 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.

SolarCool air conditioners are also more efficient during the night, when no sun shines – due to the collector acting as additional condenser


Daylight

Solar collector acts during the cooler night as additional condenser, giving higher subcooling, The consumption is the same as during the day ‐ lower heat load due to missing sun‐ The building is cooling and giving heat to the outside

An optional available bypass‐valve closes the circuit to the collector, when the heat loss of the refrigerant in the collector at a cold night may be too high


Heating with no sun during cold nights

Very cold ambient temperature at night may create unfavorable conditions to cool down the refrigerant too much

An optional valve group bypasses the flow to the solar collector for those conditions

The valve group acts only in heating mode and automatically on basis of measured conditions

When the sun delivers again free energy during the day, the valves open automatically the way to the collector to get the benefit from it

Only SolarCool and e‐volve fridge pay back their investment. Others don’t

All rights reserved

SolarCool air conditioners and fridges utilize solar energy and can pay back their investment through significant savings in energy (electricity or diesel)

Standard non‐solar systems don’t save much energy. Their today’s improvements in efficiency is marginal. Daikin cools now its PCB ‐ as in computers. They just consume and consumer and consume and consume and consume andconsume and consume and consume

SolarCool systems offer mostly a payback of less than 2‐3 years and even earn back their purchase price under 8 years. Other non‐solar systems never do that.

SolarCool reduces also the risk of compressors to fail at very hot days. They have to work less, the sun takes over much of the work

All rights reserved

• When compressors fail, they love to do it when it is very hot outside (Murphy’s law)• A damaged compressor means no refrigeration

Lost material: melted food which can’t sold anymore Lost sales and lost customers: they go to another store

• SolarCool: the hotter it is, the more takes the collector over from the compressor. This reliefs the compressor and the risk of failure goes down

Failed compressor:Failed compressor:Overheated windings SolarCool

Governments and utilities welcome your activities to reduce energy consumption ‐because they can not fulfill future demands ‐ they even sometimes subsidize solar

Consumer


UtilitiesLower costs for electricity Fullfill growing electricity demand

• Consumers are mainly interested in lower costs

• They assume 100% delivery service from the grid, meaning the grid delivers always (at 100% ) sufficient power to run the equipment

• They have no knowledge about grid and supply

• The utilities produce electricity and sell it. When they can not supply they don’t make money

• The rapid growth of air conditioning poses a thread to them since they have to invest much in larger systems/grids or they can not deliver enough electricity to fulfill all the needs causing power drops in the whole grid

• That’s the reason whygovernments subsidize (beside CO2 targets)

Bahamas Telecom is rolling out SolarCool in a 3,2 Mio program to all sites


• Bahamas Telecommunications Company Ltd (BTC), which became part of the Cable & Wireless group in 2011, has signed a $3.2m deal to install SolarCool air‐conditioning systems across many of its Bahamian locations

• Powerplus Bahamas (BTC’s energy efficiency partner) installed the trial system in May 2014, and then left it with BTC engineers to conduct their own testing. Over the following six months, BTC’s own engineers monitored SolarCool’s performance and stability in detail

• Greg Uptagrafft of Powerplus Bahamas said: “We projected an energy efficiency of around 50% at the outset, however at the follow up meeting they told us we were way out! Our test system performance was much higher than this and totally smashed our projections and more importantly BTC’s expectations.”
