Evaluation of Measurements on Parabolic Trough Collector Fields for Process Heat Integration in Swiss Dairies

Measurements from two solar process heat plants in Switzerland have been evaluated, both equipped with similar types of parabolic trough collectors. The analysis focusses on the description of the plants and the presentation of the performance of the collector fields. For this, both a daily evaluation of selected days is presented as well as a monthly evaluation is introduced where the energy delivery of the collector field is cumulated for each day and plotted against the cumulated direct irradiation on the one-axis tracked collector field aperture area.
