This report provides a detailed analysis of solar absorption cooling and solar Rankine cooling processes as represented by the National Solar Data Network (NSDN) systems. There is comprehensive data on four absorption chiller cooling systems and one Rankine cooling system. Three of these systems, including the Rankine system, demonstrated that solar cooling can be operated efficiently and provide energy savings. Good designs and operating procedures are discussed. Problems which reduce savings are identified. There is also a comparison of solar cooling by absorption, Rankine, and photovoltaic processes. Parameters and performance indices presented include overall system delivered loads, solar fraction of the load, coefficient of performance, energy collected and stored, and various subsystem efficiencies. The comparison of these factors has allowed evaluation of the relative performance of various systems. Analyses performed for which comparative data are provided include: energy savings and operating costs in terms of Btu; energy savings in terms of dollars; overall solar cooling efficiency and coefficient of performance; hourly building cooling loads; actual and long-term weather conditions; collector performance; collector area to tons of chiller cooling capacity; chiller performance; normalized building cooling loads per cooling degree-day and building area; and cooling solar fractions, design and measured.
