Abstract
High temperature heat pumps in industrial processes can enable an increase of their energy effi-ciency. The temperature swing adsorption process (TSA) enables an efficient separation of carbon dioxide. An essential part of the TSA process is a heat distribution concept, for which high tempera-ture heat pumps are a good choice, since heat must be removed at low temperature (evaporation 35-50°C) and supplied at high temperature (condensation 110-125°C). With this aim different heat pump configurations have been numerically investigated using Dymola/Modelica#^{TM}. A number of heat pump configurations, varying pre-selected refrigerants, circuit configurations, etc., have been simulated in order to compare the results by compressor size and an internal suction gas super-heater (IHX).
The results show the relative displacement volume of each heat pump configuration and give rec-ommendations of the use of the IHX as basis for investment costs and economical solutions.
