A review of vapor compression cooling systems which are driven by solar energy power cycles is provided. A novel hybrid solar-powered fuel-superheated steam Rankine cycle, which utilizes solar heat to vaporize water at relatively low temperature (100/sup 0/C) and superheats the steam by a fuel-fired superheater to 600/sup 0/C is described. This cycle has an efficiency double that of organic fluid Rankine cycles used for solar cooling, and operates at a lower temperature, at the expense of an approximately 25% fossil energy input. The resulting major reduction in the required collector area (and quality) improves system economics markedly. A 30 HP, 75% efficient steam turbine was designed for this cycle. For solar powered cooling, COP's based on (cooling energy)/ and $ (cooling energy)/(depletable resource-energy input) are recommended, at standardized test conditions.
