City of Scottsdale Courts Building Solar Space-Conditioning Project. Final Technical Report

摘要

The Maricopa County Courts Building is an existing 6800 square foot, single story structure housing offices and courtroom space. The solar system is sized to provide 65% of the annual cooling load and 100% of the heating load. An adjacent city swimming pool is connected to the system as a heat sink to provide thermal overload protection. A 25-ton absorption chiller is piped in series with the existing 25-ton air-cooled packaged chiller. Heating will be by standard hot water duct coils mounted upstream of the existing electric heaters. Freeze control is by recirculation under normal conditions, and by flush through in the event of power failure. The control sequence is given and the acceptance tests are described. Problems and solutions in constructing the system and lessons learned are discussed. Appended are the solar system schematic and as-built drawings, as well as photographs of the completed project.
