LIFE COOLER
COOLING WITH HEAT Taking a page from nature’s playbook. Evaporating and vaporising
water provides refreshing cooling. InvenSor chillers work in very much the same way.
They are powered by heat and utilise water as an environmentally safe refrigerant.
THE IDEA BEHIND INVENSOR’S INNOVATIONS Whether you talk about applications
in industry, showrooms, IT departments or community facilities: Anyone familiar with
cooling or air conditioning knows that this needs a lot of power and, thus, generates
high cost. Not so when using an InvenSor chiller! Drawing on waste heat that would
otherwise be left unused, our machines generate cooling that is directly usable.
MAKING PERFECT SENSE The application of this principle will not only double your
monetary savings but also afford you efficient and environmentally compatible cooling.
Unlike conventional systems that consume great amounts of electrical power, InvenSor
chillers utilise waste heat generated by, for instance, combined heat and power stations,
thermal solar plants, and industrial production processes.
AN INGENIOUS IDEA
Using water as a refrigerant and heat as a power source. This environmentally
safe idea has already received multiple awards and proven its - ecological and
economic - value in a host of buildings and commercial operations.
WE USE WASTE HEAT
FOR CLEAN COOLING
INVENSOR CHILLERS save up to 70 % in electrical power consumption compared to
conventional systems and, thereby, help reduce operating costs significantly. No matter
which type of waste heat is used to power them, the machines always operate with
utmost efficiency and ease of use.
COOLING IS NO LONGER A CONCERN There are no actively moved components inside
the cooling chamber. As there is no need to open it for inspection or maintainance
purposes it is welded tightly. Thanks to the InvenSor ActiVac® technology, the cooling
chamber is maintainance-free.
MAKE USE OF THE WASTE HEAT generated by your combined heat and power station
or solar plant. Put your plant’s process waste heat to good use. Regardless of where you
produce your excess heat, InvenSor chillers can convert this heat into usable cooling.
MADE WITH LOVE
The care and attention we invest in our InvenSor chillers show in every detail.
Integrated hydraulics, maintenance-free cooling chamber, standard internet
connectivity, and a touch screen controller that is utterly amazing. Plug & Chill.
COOLING WITH HEAT
Using waste heat as driving energy: InvenSor chillers work on the
principle of adsorption. They generate cold water and transfer the
excess energy to a re-cooler outside of the building.
WORLD CHAMPION
A single gram of adsorption material has an inner surface
the size of a football field. This is the driving force in InvenSor’s
compact chillers.
THE INVENSOR
ADSORPTION
TECHNOLOGY
ZEOLITE COAT ON AN ADSORBER
THE EVAPORATION SURFACE on a clay jug is sufficient to keep several litres of water
cool for a number of hours. Just imagine the amount of cooling you can generate using
the surface area available on several football fields. This enormous cooling capacity is
exactly what is at the heart of every InvenSor chiller: a gigantic surface in a miniscule space.
SMALL DEVICE, TREMENDOUS IMPACT The piece of an adsorber shown in the picture
belongs to the heart that drives the InvenSor adsorption chiller. The sorption process
provides high power and efficiency of refrigeration in the evaporation chamber by
extracting water vapor.
LARGE CAPACITY, LOW DRIVING TEMPERATURE The two adsorbers built into the
InvenSor chiller are operated alternately in adsorption mode (vapor extraction) and
desorption mode (regeneration with heat). Varying with the type of machine, temperatures
as low as 60°C (140°F) are sufficient to achieve excellent capacity and efficiency.
THE PARIS WORLD FAIR IN 1878 was the first event that introduced the world to a
sorption machine using solar power to produce a block of ice. Since then, ABSORPTION
machines have been commonplace for many years. InvenSor’s ADSORPTION technology
is now raising the bar in terms of capacity density and ease of use.
ADSORPTION MATERIAL THROUGH AN ELECTRON MICROSCOPE
Zeolites are characterised by their regular arrangement of cavities and
channels. Depending on their size, the pores are referred to as micro or meso
pores. These materials offer an exceptionally large interior surface boasting, in
some cases, more than 1,000 square metres per gram. The greater the surface,
the more powerful the sorption process.
GENERATE POWER,
HEAT & COOLING
WITH YOUR CHP UNIT
TRIGENERATION
Benefit even more from your CHP by cooling or air conditioning.
Enjoy an independent electricity supply year-round.
Across the globe, we experience a steady increase in energy cost. Combined heat and
power stations (CHP) provide for greater independence of rising electricity rates and
for a more efficient utilisation of energy. The more hours your CHP is in use, the more
power and, at the same time, the more heat it generates for you. However, what to do
when you don’t need the heat that is being produced? What if you need electricity for
cooling, but your CHP is operating at reduced capacity? It would certainly be ideal
if you could use the heat to generate cooling energy and, thereby, produce and save
electricity at the same time.
TRIGENERATION A chiller made by InvenSor allows you to generate cold water and use
the heat produced by your CHP unit as operating power. This represents the ultimate additional benefit any combined heat and power station can yield. When outside
temperatures are low, an InvenSor chiller can even supply direct cooling via the exterior
re-cooling unit (free cooling function). In this case you can use the heat produced by the
combined heat and power station for heating. Triple use of primary energy. This is as good
as it gets.
WHEN COMBINING IT WITH AN INVENSOR CHILLER, YOUR CHP UNIT WILL AFFORD
YOU EVEN GREATER INDEPENDENCE. THAT PAYS OFF!
EXAMPLE: MITSUBISHI HIRATSUKA PLANT | JAPAN
To make efficient use of exhaust heat from a CHP unit, three InvenSor chillers
(30 kW) have been installed. The machines replace a 37 kW absorption chiller
delivering cold water for air conditioning.
EFFICIENT COOLING
WITH PROCESS
WASTE HEAT
PROCESS WASTE HEAT THAT IS HELPING YOU SAVE
In many production rooms, heat is produced in abundance.
You can use this heat efficiently for process cooling or air
conditioning, making optimal use of energy in your company.
The requirements for chillers and air conditioning systems have seen a dramatic increase
as emissions of CO2 must be reduced. There is, however, a question that is even more
urgent: How can we produce refrigerants that are sustainable and comply with the requirements stipulated by law? InvenSor offers solutions suitable to overcome both of these
challenges.
COOLING OF MACHINERY InvenSor chillers can easily be incorporated into an existing
cold water system. The possible applications are just as diverse as the cooling requirements of machinery and equipment, for instance, in production, medical technology and
data processing.
COOLING OF ROOMS A perfectly tailored air conditioning system can not only increase
efficiency but also the comfort level in the room. Showrooms, offices, conference halls,
production facilities, laboratory buildings – the higher the cooling requirements, the
greater the savings in operating costs you can achieve with an InvenSor chiller.
AN INVENSOR CHILLER ALLOWS YOU TO USE YOUR PROCESS WASTE HEAT IN A
WORTHWHILE AND EFFICIENT WAY.
EXAMPLE: WIKANA KEKS UND NAHRUNGSMITTEL GMBH | GERMANY
Wikana employs InvenSor technology to air-condition their production
facilities. This “Company of the Year 2011“ uses three adsorption chillers with
recovered heat from their baking ovens. The intelligent utilisation of the waste
heat helps the company save approx. EUR 11,000 in energy costs every year.

WITH YOUR SOLAR
THERMAL PLANT
FOR A COOLER LIFE
Environmentally sound cooling.
Cooling is particularly important with the more intense radiation of the sun in the summer
time - be it for private or commercial purposes. An InvenSor system allows you to achieve
previously unattainable goals.
USING THE SUN TO GENERATE COLD Until now, solar thermal plants have only been
used for heating and domestic hot water. Thanks to InvenSor chillers, the sun’s energy
can now be used for solar thermal air conditioning. Eco-friendly as can be.
RENEWABLE ENERGY – FOR THE SAKE OF OUR ENVIRONMENT Electrical cooling
requires a tremendous amount of energy. This puts a huge burden on the environment
and on your wallet. Utilising solar power to generate heat is a giant leap towards a
sustainable energy supply.
TECHNOLOGY FOR DEMANDING CUSTOMERS Heat-powered chillers allow their users
heating and air conditioning with integrated systems on the cutting edge of technology.
This approach is not only smart, but also provides for increased independence.
RISING TEMPERATURES CALL FOR IMPROVED COOLING.
EXAMPLE POUSADA DO PARQUE | BRAZIL
Since 2011 the Cuiabá eco-hotel uses solar energy for heating and cooling.
Cold water from an InvenSor HTC 18 chiller is used for cooling the walls of
the building.
