Solar Adsorption Chilled Water (SACW) system is similar to vapor compression the system in which the compressor is replaced by a solar heat-driven adsorption bed. The adsorption bed is integrated with an evacuated tube solar collector (ETC/Bed REactor) and contains a
porous adsorbent medium (low-grade charcoal). The adsorbed content of refrigerant varies cyclically, depending on the adsorbent temperature and system pressure, which varies between a maximum limit set by the condensation pressure and a minimum limit imposed by the evaporation pressure. The refrigerant used is Methanol (CH3OH) as it has a greater affinity towards salt (Activated carbon). Solar ETC is attached to the bed reactor for the heat generation process. The cycle contains the following:
2-Bed reactor tank.
3-Solar collector (ETC/water).
6-Activated carbon is used as a bed salt.
7-Methanol CH3OH is used as the main refrigerant.
8-Cost calculations for each unit.
The user will be able to add more different metals or materials to increase the thermal conductivity of the bed.
**MatLab-SimuLink should be used to run the model.
