Ecovat has requested a patent for a thermally cooled PVT panel. In combination with the Ecovat, this panel delivers energy yield on three levels. 1. Electric – daytime insolation 2. Thermal – daytime low-grade exergy 3. Thermal – at night low-grade exergy For more information visit our website or contact us.

2. Creating value through
heat storage

3. Storage was
the missing link!

4. Do we have an
energy problem?

5. Do we have an energy problem?
• Demand is raising
(population growth
and growth of world
economic)
• Supply of fossil energy
is decreasing (running
out)
• Dependency is
growing (risks are rising)
• Climate is changing,
due to > Co2

6. There is no
energy problem!

7. There is no energy problem!

8. There is no energy problem!
• Sun and wind are not
always there when you
need them.
• Sustainable energy
production means
direct consumption.
• Demand and needs do
not fit.
There is an energy
storage problem!
For climate reasons
focus on sustainable
energy!

9. That’s why I invented Ecovat!
The first thermal storage system that can:
1.Store high temperatures (up to 90 C)
2.Over the seasons (> 6 months)
3.With only an average thermal loss < 10%

10. That’s why I invented Ecovat!
The first thermal storage system that can:
1.Store high temperatures (up to 90 C)
2.Over the seasons (> 6 months)
3.With only an average thermal loss < 10%

11. Resume:
1. 30% more energy efficiency
2. 90% savings
3. 93% exchanging
4. No architectural impact
5. Not visible
And cheaper in cost
price then competition

12. To load Ecovat I invented Ecovat PVT !
The first thermal PVT system that can:
1. Produce maximum electricity by cooling the PV-cells during the day
2. Produce low exergy temperature (5 – 25 degrees) during the day
3. Regenerates low exergy layer in the Ecovat (5 – 15) during the night
4. Exchange cold at the winter (-10 +5) and stored the cold in the Ecovat

13. Proven technology
Patent and IP: P100171NL00
Improvement of efficiency by forced air convection (no conductivity)
Innovative with forecast based control software which

14. Ecovat PVT module 1.0 x 2.0 m1
q = 500 W/m2
t = 50
t = 10
t = 5
1. 1000 W/m2 =
Air = (m3 x 1,293 x 710 x (50-10))/3600 = 120 m3/h
(air speed < 1,5 m1/s)
2. 1000 W/m2 =
Water = (m3 x 4186 x (10 - 5))/3600 = 0,17 m3/h
(water speed < 0,25 m1/s)
3. Fan Ø 200 =
140 m3/h = 83 CFM (1 CFM = 0,47 Ltr/sec)
4. Electricity fan = 4 Wh (83 * 0,47 * 3600) = 140 m3/h
Electricity pump = 15 Wh
Electricity total = 19 Wh
COP > 50 (1000/19)

15. Thank you for
your attention!
