4. Award from World Economic Forum in Davos
• ClimateWell was awarded by the
y
World Economic Forum in Davos the
”Technology Pioneer 2007” status
based on:
– Technology leadership
gy p
– End user profitability
– Company leadership for global expansion
• Among former years’ Technology
years
Pioneers you will find companies such
as Google, Cambridge Silicon Radio
and Millennium Pharmaceuticals
• As a consequence of this, TIME
Magazine published articles about
ClimateWell on the 4th of December
2006
• This represents a global acknow-
ledgement f Cli t W ll and it
l d t for ClimateWell d its
solutions for solar powered indoor
climate
6. How does the technology work?
• Fundamentally an absorption process, that converts heat to cold.
• This process was in fact used already in gas-fired refrigerators
developed more than 100 years ago.
• ClimateWell has improved this process drastically by adding a
patented energy storage solution:
– Resulting in a de-coupling of the charging (where energy is received
from the sun or the generator) from the output (where heat or cold is
distributed to the house).
)
• The new process enables a continuous cooling/heating of the
building,
building even with a highly volatile source of energy like the sun
We charge energy whenever it is available and use it when needed.
7. The Technology
Triple-phase absorption heat pump system, or a
” Chemical heat pump with hybrid substance”
Using a hygroscopic salt – LiCl –
with an energy density of 300+ kWh/m3
In cooling mode the system can produce an output
temperature of 44 to 66 ºF (7 to 17 ºC).
ºC)
8. Energy storage
• ClimateWell’s products include an integrated energy storage
• The energy is fed into the storage as hot water, typically
– 165 – 220 ºF (75-105 ºC)
( )
– With a stable or fluctuating power of 0-20 kW.
– The typical flow rates are 240GPH (15 l/min).
• The charging process is very robust and fluctuations in temperature,
power or flow rates do not damage the unit, it only affects the charging
time.
• The discharging is totally independent of the charging and can hence
take place whenever needed. During discharging the unit has a “hot
side” and a “cold side”, with some 40 K of difference in temperature.
, p
– The cold side can be used for Air Conditioning and
– the hot side for pre-heating of hot water or for space heating.
• The hot and cold side can be used simultaneously, for maximum
y
energy efficiency
9. Thermal sources
• Solar thermal panels: The products are designed to be coupled with
solar th
l thermal collectors:
l ll t
– Either flat plate or vacuum solar collectors
– The units are designed to always receive the solar energy and over heating of
the collectors is hence avoided
• An electrical generator: For off grid sites it is possible also to use
waste heat from an electrical generator to power the ClimateWell
t h tf l ti l t t th Cli t W ll
units:
– This enables efficient tri-generation of electricity, heating and cooling. Ideal for
energy autonomous residence areas
– The thermal powered Air Conditioning dramatically reduces the need for
electricity and the whole electricity generation installation can therefore be
downsized
• Waste heat from industrial applications, i.e. steel mills
10. The heat sink
• There is a need for an efficient heat sink, where the Air
,
Conditioning heat and the condensation heat of the
charging is dissipated
• Heat sink options include:
– Pre-heating of hot water
– Geothermal heat exchangers
– Heat exchangers in the sea
– Cooling towers
– Air cooled condensers

• ClimateWell has sold 158 solar cooling installations to date out of
which the majority are in Spain. The aim is to deliver 300 units to
the Spanish market in 2008
• Solar cooling is now definitely technically available from 10 kW
up to several MW of cooling capacity. A whole range of heat
sinks has been developed and tested in real life installations for
different project characteristics
• There is a user friendly ClimateWell system dimensioning tool
based on TrnSys for solutions engineering of indoor climate
solutions
• ClimateWell is conducting professional training of installers and
engineers in Spain and in Italy. Some 250 installers will be
Italy
trained during the first 6 months of 2008
• Solar cooling is still a early stage market but the implementation
pace i picking up as equipment, system k
