IEA HPT Annex 58: High-Temperature Heat Pumps
The developments in the field of high-temperature heat pumps in recent years have been various and wide-ranging, but still they are rarely used in industry.
In order to give potential users of high temperature heat pumps an overview of the technological possibilities and to facilitate the necessary steps in the implementation of the technology, existing knowledge of the partners from previous projects will be structured and completed with new knowledge in relevant sections.
In a first step, the actual status and further research requirements for high temperature heat pumps will be collected and documented. The focus will be on systems that are available and close to the market in Austria.
Besides the variety of heat pump systems themselves, the integration potentials for industrial processes are also very different. By identifying and evaluating integration potentials for specific industrial processes, as well as the theoretical analysis and evaluation of technical solutions, the project aims to further enhance the information for potential users about the technological possibilities of high-temperature heat pumps. Moreover, heat pump manufacturers are to be provided with an incentive for the further development of the technology.
Location-related aspects play an important role in the practical implementation of high temperature heat pumps. Therefore, these aspects will be identified and their influence on planning and acquisition costs will be documented.
A checklist, which guides especially end users step by step through the entire procurement process, and also communicates the standards and guidelines to be complied with in Austria, is another important project result, which should contribute to the reduction of non-technical market barriers. In addition, an overview of the advantages and disadvantages of various test procedures for high-temperature heat pump systems - factory and site acceptance tests - as well as the equipment required for these tests will be compiled in order to support heat pump manufacturers, integrators and end-users in this step.
The result is a structured overview of high-temperature heat pumps in the form of reports and checklists, which are disseminated nationally and internationally to the relevant target groups, especially potential end users, manufacturers, consultants, energy planners and political decision-makers.
