Abstract

This paper presents data from measurements made on an adsorbent energy storage bed. Comparisons between air outlet states predicted by a numerical model with constant system properties and the data show good agreement when the system is operated in a charge-discharge mode similar to the situation in a solar system. However, the agreement is not so satisfactory for the classical single blow case, and the discrepancy is attributed to the assumption of constant system properties. The long term storage ability of these beds is demonstrated by first charging the test bed, allowing it to cool to around 21°C and then extracting energy by admitting air to the bed at temperatures between 25 and 30°C.
