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. Five solar cooling systems were monitored in 1982; four of these have absorption chillers and one has a Rankine engine. Of the four absorption chillers, two are directly solar fired and two are boiler fired using solar energy as the preheat to the boiler. The composite data for the five sites covers the period from September 1981 through December 1982. There are 36 site months of data covered in the report. These are all commercial systems with buildings ranging in size from 5000 to 84,000 square feet. There are three evacuated-tube, one flat-plate, and one linear concentrating collector systems. Analyses performed for which comparative data is provided include: Energy savings and operating costs in terms of Btu; Overall solar cooling efficiency and coefficient of performance; Hourly building cooling loads; Actual and long-term weather conditions; Collector performance; Chiller performance; Normalized building cooling loads per cooling degree-day and building area; and Cooling solar fractions, design and measured. Conclusions and lessons learned from the comparative analysis are presented.
