Supplementary monitoring of Central Solar Heating Plant in Marstal, Denmark.

The Central Solar Heating Plant in Marstal, Denmark, is one of the largest of its kind. The plant consists of 9000 m2 solar collectors, a steel tank of 2100 m3 and a 3700 m3 seasonal gravel-pipe storage.
The plant has been monitored since 1996. The first analysis showed lack of data collected at the plant for research purposes. Hence a supplementary monitoring programme was carried out during the Summer 1999. A large amount of data has been collected about temperatures, mass and energy flows in the system, control values for the control system and much more. One collector row has been monitored in detail by measuring all the temperatures between the individual collector modules. One-minute intervals have been chosen for data collection. The data will be applied for a.o. computer simulation program validation in the Ph.D.-Thesis of the author.
