Award from World Economic Forum in DavosAward from World Economic Forum in Davos

• ClimateWell was awarded by the yWorld Economic Forum in Davos the ”Technology Pioneer 2007” status based on:

– Technology leadershipgy p– End user profitability– Company leadership for global expansion

• Among former years’ Technology• Among former years Technology 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 DecemberClimateWell on the 4 of December 2006

• This represents a global acknow-l d t f Cli t W ll d itledgement for ClimateWell and its solutions for solar powered indoor climate

Technology

How does the technology work?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: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 even with a highly volatile source of energy like the sunbuilding, even with a highly volatile source of energy like the sun

We charge energy whenever it is available and use it when needed.

The TechnologyThe 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 outputtemperature of 44 to 66 ºF (7 to 17 ºC)temperature of 44 to 66 ºF (7 to 17 ºC).

Energy storageEnergy 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 yenergy efficiency

Thermal sourcesThermal sources

• Solar thermal panels: The products are designed to be coupled with l th l ll tsolar thermal collectors:

– 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 avoidedthe collectors is hence avoided

• An electrical generator: For off grid sites it is possible also to use t h t f l t i l t t th Cli t W llwaste heat from an electrical generator to power the ClimateWell

units:– This enables efficient tri-generation of electricity, heating and cooling. Ideal for

energy autonomous residence areasenergy 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

The heat sinkThe 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 seaHeat exchangers in the sea– Cooling towers– Air cooled condensers

Conclusions 1Conclusions, 1• 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 kWSolar 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 characteristicsdifferent 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 beengineers in Spain and in Italy. Some 250 installers will be trained during the first 6 months of 2008

• Solar cooling is still a early stage market but the implementation i i ki i t t k l d i ipace is picking up as equipment, system knowledge, engineering

software and installer knowledge is reaching acceptable quality

Final conclusionFinal conclusion

• Solar cooling will have a major impact on EU’s ability to reach the CO2 objectives and provides an excellent route to highly energy efficient buildings

• Solar Cooling from ClimateWell is an “A” Technology
