This Task takes a look at the components of the machines, the internal parts as e. g. the exchangers, ejectors, covering materials, or chemical components as the working pairs or the absorptive materials.

Similarly to Task B, previously to the comparison, a methodology of properties characterisation must be described to create with them a database with the available and upcoming materials, their stability and their known problems and incompatibilities.

Although the main focus lies on the internal elements, also the external ones are going to be studied as can be the heat rejection systems and all the auxiliary components existing in a facility.
