Introducing DAIKIN, leading air-conditioning innovator

HYBUILD is a group of 21 partners from 9 countries. Every month, a new HYBUILD partner is introduced in our Blog section. Today,  DAIKIN, a leading innovator and provider of advanced, high-quality air conditioning solutions for residential, commercial, and industrial buildings. DAIKIN is involved in HYBUILD through its Greek branch.

DAIKIN in a nutshell

Daikin presence in the Greek market goes back to the 80s. In 2004, Daikin Europe NV established a branch in Greece, Daikin Europe Hellas Office. In 2006, Daikin Europe Greek Office became a 100% subsidiary of the Daikin Group, under the name of Daikin Airconditioning Greece SA. Since 2006,  Daikin Greece has established a strong sales network of professional installers offering excellent pre and after sales support to its residential, commercial and industrial customers on a B2B and B2C basis. Daikin Greece occupies more than 30 people with a sales turnover in FY17 to reach 44M€ in Greece and Cyprus. In addition to air conditioning, Daikin Greece has established itself in the Greek market of heating systems and refrigeration, and has also developed advanced direct technical service activity.  Especially for heating, Daikin Greece is driving the way of decarbonization of the market playing a leading role in the introduction of the Air to Water (A2W) heat pump technology since 2007. Daikin Greece is an active member of  Applia Hellas local branch of Applia (former CECED) and member of the Union of Greek Companies for Heating and Energy (UHHE). Daikin Greece is certified according to the standards ISO 9001:2015 & ISO 14001:2015 for its quality and environmental management systems. Daikin is committed to providing homes, businesses and industry with the most efficient and safest solutions to meet all cooling and heating needs, today and in the future. DAIKIN is aware of its responsibility to protect the environment in everything it does: all its policies, practices and processes are developed and implemented with environmental sustainability in mind.


DAIKIN, as a technological leader in the HVAC market, is in charge of the selection, modification and provision of the heat pumps needed for the HYBUILD hybrid storage system for the Mediterranean climate. The heat pump is a key element of the overall HYBUILD system, since it allows the efficient conversion of the electric energy produced by the PV panels in thermal energy, which can be either stored (in the Phase-Changing Material (PCM) storage, connected to the evaporator, or the sorption storage connected to the condenser), or directly cover the space cooling and/or DHW and heating demands. With the compressor connected directly to a Direct Current (DC) bus, this configuration will further enhance the electrical efficiency of the system.

Besides, DAIKIN’s long experience in heat pump technology and market, will lead to useful recommendations within HYBUILD regarding the integration of the subsystems with the selected heat pump and the economic analysis of the whole system.

Introducing FAHRENHEIT, pioneer in adsorption technology

HYBUILD is a group of 21 partners from 9 countries. Every month, a new HYBUILD partner is introduced in our Blog section. Today, FAHRENHEIT, a company specialised in cooling innovation.

FAHRENHEIT in a nutshell

FAHRENHEIT is a pioneer in adsorption technology. Based in Germany, the company designs and manufactures the most advanced adsorption cooling devices on the market. It applies innovative research to delivering energy efficient cooling solutions. Its products have made their way into hundreds of installations worldwide across a diverse range of industries and applications.

FAHRENHEIT was founded in 2002 as a spin-off from Fraunhofer Institute for Solar Energy Systems (ISE). From the very beginning, research and technological excellence have been the pillars of the company.  Its original research coupled with a keen awareness of our customers’ requirements resulted in ground breaking patents in energy solutions. FAHRENHEIT develops and manufactures innovative and efficient solutions to generate and store cold anywhere cold is needed and waste heat is available.

Adsorption chillers by FAHRENHEIT can be used wherever there is residual heat available. Its cooling technology reaches a new dimension of energy efficiency because it does not rely on electrical power for cooling. Its chillers and its adsorption modules are widely used in industrial manufacturing, for air conditioning, in data centers, in solar cooling and in various other applications. They are also ideally suited for combined heat and power plants – turning them into tri-generation units –, and they can save substantial amounts of energy and CO2 emissions in mobile applications such as cars and transport cooling.


FAHRENHEIT chillers operate on the principle of adsorption. Adsorption occurs when molecules of a liquid (in our case water) adhere to the surface of a solid (in our case zeolite crystals or silica gel). This causes the liquid to evaporate, generating cold. Once the solid material is saturated, heating it will cause it to release the adsorbed liquid, allowing the process to start again.

Within the HYBUILD project FAHRENHEIT focuses on the development of advanced adsorption heat exchangers for the Mediterranean region and the efficient integration of the vapour compression heat pump with the adsorption storage part in order to enhance its EER.

Meet our staff

The following staff is involved in the HYBUILD project:

Dr. Walter Mittelbach (CTO)

Walter Mittelbach is the Chief Technology Officer of FAHRENHEIT. He founded SorTech AG, the predecessor of FAHRENHEIT, in 2002. He holds several patents on adsorption technology and, together with his team, won numerous awards for developing efficient and compact adsorption chillers.

Walter Mittelbach laid the foundation for FAHRENHEIT as a researcher at Fraunhofer Institute for Solar Energy Systems (ISE). He studied physics at Graz University and at Free University Berlin.

Dr. Ralph Herrmann (Head of R&D)

Dr. Ralph Herrmann is in charge of research and development at FAHRENHEIT. Trained as a chemist, Dr. Herrmann dedicated a large part of his professional life to researching and evolving zeolite crystals. He holds numerous patents in this field. Since 2004, he has been applying his expertise at FAHRENHEIT.

Prior to joining FAHRENHEIT, Dr. Herrmann obtained his Ph.D. from the University of Halle and spent several years at the University of Erlangen as a researcher and as a lecturer for chemical engineers.

Ursula Wittstadt

Ursula Wittstadt joined FAHRENHEIT in 2016 to work in the development of the next generation adsorption chiller and the co-ordination of research projects.

Ursula Wittstadt holds a diploma in Energy and Process Engineering of the Technical University in Berlin. Before joining FAHRENHEIT she worked as a researcher and project leader at the Fraunhofer Institute of Solar Energy Systems (ISE) in Freiburg within the field of adsorption heat exchanger development.

EASE-EERA Energy Storage Technology Development Roadmap 2017

The European Association for Storage of Energy (EASE) is the voice of the energy storage community, actively promoting the use of energy storage in Europe and worldwide.

The European Energy Research Alliance (EERA) is an alliance of European public research centres and universities. It is one of the cornerstones of the European Strategic Energy Technology Plan (SET-Plan).

EASE and EERA released the 2017 update of their roadmap which provides a comprehensive overview of the energy storage technologies being developed in Europe today and identifies the R&D needs in the coming decades. On this basis, the roadmap provides recommendations for R&D policies and regulatory changes needed to support the development and large-scale deployment of energy storage technologies. The aim is to inform policymakers for research, innovation, and demonstration in the energy storage sector in order to further strengthen Europe’s research and industrial competitiveness in the energy storage industry.
