Selective water sorbent for solid sorption chiller: experimental results and modelling.

Type of article: Article, IJR article

Summary

In this paper the experimental results of a lab-scale chilling module working with the composite sorbent SWS-1L (mesoporous silica gel impregnated with CaCl2) are presented. The interesting sorption properties of this material yield a high COP = 0.6 that gives a promising alternative to the common zeolite or silica gel for application in solid sorption units driven by low temperature heat (T less than or equal to 100 °C). The measured low specific power of the device is a result of not optimised geometry of the adsorber and of the pelletised shape of the adsorbent. Heat transfer optimisation is currently under progress to increase the specific power. The experimental results were compared with those of a mathematical model able to describe the dynamic behaviour of the system. The model was used to study the influence of the main operating parameters on the system performance.
