Solar Thermal Collectors
• Collectors are built to order
• Specialized in large scale thermal collectors manufacturing – up to 18m2 per unit
Advantages
• Higher energy output
– Flow of fluid is designed to suit application
• Easier and faster installation
• Less connections and piping
– Lower flow indicates smaller pumps
Standard flat plate < > HT -collector
HT – collector has 2 air chambers better insulation
higher performance at high temperatures up to 110°C

Solar Cooling
Applications
Solar Cooling – the advantage
peak of solar radiation and
peak of cooling demand
match perfectly
• We can use the same radiation that creates the
cooling demand to cover it.
• Avoids electricity peaks and extreme operations
on the electric distribution grid.
• Solar Cooling saves the most expensive
electricity!
A brand new technology ?
Expo 1878 in Paris, A. Mouchot produces ice with solar energy
Why solar air conditioning ?
• Electric Energy Savings
– Electric COP Solar Cooling System incl. recooling ~10
– Electric COP Compression Chiller Syst. incl. recooling ~2.4
reduced electric consumption by 70-80%
• More stable energy expenses
• CFC Free Chillers – No Ozone Depleting Potential
• LEED certification - up to 10 additional points possible
• Quiet operation – no vibrations
• Reliable operations – no wear and tear on pistons or
screws as there are no such stressed parts
Long lifetime of absorption chillers. No moving parts. This one is > 70 years old !
