Résumé

In order to get a better understanding of the performance of the sorption reactor/heat exchanger design and sorbent bed loading, an experimental setup has been developed. This setup allows measuring the performance of various ammonia-sorbent reactions with various sorption reactor/heat exchanger designs under well-controlled and well-monitored process conditions similar to the heat pump conditions. This setup measures the ammonia uptake and release under well-controlled conditions with temperatures that can be varied from ambient temperature up to 200°C and ammonia pressures that can be varied between 0.02 to 2 MPa. These conditions can be set independently and repeated at regular time-intervals. Besides mass-flow meters, pressure and temperature sensors, the setup also contains an endoscope to observe the macroscopic structural changes in the material during uptake and release of ammonia. After initial testing, the setup is now ready for the first experiments on different heat exchanger designs and sorbent materials. The paper includes a description of the setup and the first experimental results.
