Selective water sorbent for solid sorption chiller: experimental results and modelling
TLDR
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.Abstract:
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 4100 � 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 are compared with those of a mathematic model able to describe the dynamic behaviour of the system. The model is used to study the influence of the main operatingread more

A family of new working materials for solid sorption air conditioning systems
TL;DR: In this paper, a family of new working materials, called selective water sorbents, is presented for sorption air conditioning, which are composites "hygroscopic salt inside porous matrix with open pores" and possess intermediate behavior between solid adsorbents, salt hydrates and liquid absorbents, so that their water sorption properties can be controllably modified by varying porous structure of the host matrix, chemical nature of the impregnated salt and the amount of the salt inside the pores.
