Exergy concept combined with pinch based approach are used for studying the optimal integration of energy conversion systems. The analysis first considers the representation of the hot and cold composite curves of the process and defines the energy and the ...
This project is evaluating a heat pump cycle with midstage injection at scroll compressors. The injected refrigerant is evaporated partially by an internal heat exchanger (fig. 2.1). A glycol-water heat pump with 12 kW heat capacity at B-5/W50 was built an ...
In the frame of the European Fusion Technology Programme, the Forschungszentrum Karlsruhe and the Centre de Recherches en Physique des Plasmas, CRPP, Villigen, develop a 70 kA current lead to demonstrate the feasibility of the usage of High Temperature Sup ...
The behaviour of a pile subjected to thermo-mechanical loads was studied in situ with the aim of quantifying the thermal influence on the bearing capacity of heat exchanger piles. To accomplish this, a pile situated in a building under construction was equ ...
In the frame of the European Fusion Technology Programme, the Forschungszentrum Karlsruhe and the CRPP Villigen are developing a 60 kA current lead for the ITER Toroidal Field Coils using High Temperature Superconductors. In part 2 of the task, two 10 kA H ...
This work addresses the indirect heat integration (i.e. resorting to intermediate heat storage) and the direct heat integration (i.e. heat exchanges between coexisting process streams) of batch processes. Tools and methods for the targeting of these two li ...
Among the structure independent approaches of process integration, pinch technology has been shown for continuous processes to be extremely powerful to develop energy efficient processes and enhance synergic effects within and between processes. The earlie ...
We have improved the model presently used in the thermo-hydraulic code Gandalf, adapting it to cable-in-conduit conductors with central cooling channel such as those developed for the model coils of ITER, In particular the helium flow in an arbitrary numbe ...
Steam production units (HRSG and HSSG) of ISCCS include several heat exchangers (economizers, evaporator, superheater, reheaters, etc.). The knowledge of the extended composites as a function of the solar input, allows the determination of the most critica ...
The capacities of performance improvements of low and mid-size heat pumps are studied in this project. For the new buildings market, the components of the heat pump match already well the requirements for high performance and monovalent heating. Minor impr ...
