Solar Cooling : Description of Solar Cooling

TSolar Cooling is the term used to describe the use of solar thermal energy or solar electricity to power a cooling appliance. There are five types of solar cooling technologies: absorption cooling, which typically uses solar thermal energy to vaporize the refrigerant; desiccant cooling, which can use solar thermal energy to regenerate (dry) the desiccant; vapor compression cooling, which can use solar thermal energy to operate a Rankine-cycle heat engine; and evaporative coolers ("swamp" coolers), and air conditioners/heat-pumps that can by powered by solar photovoltaic systems.
