Absorption cooling is the most commonly used method of solar cooling.
In the absorption cooler, heat is supplied to the generator in which a refrigerant is driven from a strong solution. The refrigerant is cooled in the condenser and allowed to expand through the throttling valve. The cooled, expanded refrigerant receives heat in the evaporator to provide the desired cooling, after which the refrigerant is reabsorbed into the cool, weak solution in the absorber. The pressure of the resulting strong solution is increased by pumping and the solution is available to repeat the process.
Adsorption Cooling
-Adsorption is the use of solids
for removing substances from gases and liquids.
-The phenomenon is based on the preferential partitioning of
substances from the gaseous or liquid phase onto the surface of a solid
substrate.
Adsorption phase 1
-Heating
and pressurization
Adsorption phase 2
-Heating
and adsorption + condensation
Adsorption phase 3
-Cooling
and depressurization
Adsorption phase 4
-Cooling
and adsorption + evaporation
Desiccant Cooling
Flow Chart of Desiccant Cooling
Desiccant cooling systems, on the other hand, may be designed for open-cycle operation, since the only circulating fluids involved are air and water. The basic concept is to dehumidify air with a desiccant, evaporatively cool the dehumidified air, and regenerate the desiccant with solar-derived thermal energy.
