The work on IEA HPP Annex 32 is structured in 4 Tasks
Task 1 - Market and systems survey
- Evaluation of different system configurations of integrated heat pump systems for heating and cooling applications in the market and under development including an
- Analysis of different demand structures (DHW, space heating, cooling, ventilation,
de-/humidification) under consideration of possibilities of passive cooling, shading etc.
- Ambient sources for heating and cooling energy (outside air, exhaust air, ground, combination of the formerly mentioned)
- distribution systems attached to the generator unit (surface heating and cooling systems, air distribution, ground-coupled cooling)
Task 2 - System assessment and comparison
- Evaluation and/or development of calculation methods for the systems to be investigated
- Comparison of the different systems with regard to the overall energy performance for the different building services among each other and with
non-heat pump system solutions
- Evaluation of the control of the systems
- Economic evaluation of the system solutions for heating and cooling
Task 3 - Field testing of integrated heat pump systems
- Establishing of an appropriate measuring concept and instrumentation for comparison with the assessment carried out in Task 2
- Functionality check and commissioning of test plants and derivation of key values for system performance
- Summarising and comparison of results for best practice samples in the design guidelines to be developed in Task 4
Task 4 - System assessment and comparison
- Derivation of design guidelines of the results of Task 2 and Task 3 with regards to the requirements
- Transfer of the results to standardisation committees to be integrated in standard calculations if applicable
- Documentation of best practice systems and typical optimisation potentials
