Work Package 2 has the focus on the requirements specification for the development phase. To find the right configuration und solutions, it closely cooperates with Work Package 6 to identify and assess the capabilities of the new R744-System. This will be continuously supported by providing customer needs and requirements to meet the comfort criteria of passengers in a wide operating range including hygienic requirements..
In Work Package 2 the following goals for the development of requirements specifications are defined:
- Development of overall architecture requirements for R744 – Air conditioning systems for railway systems including modularity, scalability and adjustability on component and system level
- Development of architecture requirements for R744 – Air conditioning systems for railjet based on the overall R744- Air conditioning system architecture requirements
- Examination and studies for the capabilities of existing R744 components and air conditioning systems with focus on increase of energy efficiency, cost efficiency, mass produce ability. Bases are the results of GreenHVAC4Rail and the existing technologies of the automotive sector.
Additionally, Work Package 2 monitors and controls the realization of the developed requirement specifications in the next project phase. This focus ensures that the requirements will be realized according to the overall project goals and the identified specifications. Moreover, it is responsible for the assessment of specifications changes in the development phase, in close cooperation with Work Package 6 and 7.
