2 Recording of monitoring data
The solar cooling plant was installed in spring 2009 and the system operation was monitored
in summer 2009 and 2010. In summer 2009 the monitoring data transfer contained gaps for
the duration of some hours to several days, caused by the used monitoring recording
software. Therefore, a new monitoring server was installed at AIT for summer 2010 which led
to a continuous recording of monitoring data in the second summer.
Approximately 75% of the monitoring data from the summer 2009 were recorded. This data
represents all relevant weather conditions for Vienna. As a result, it was possible to make a
first evaluation of the energy performance of the solar cooling plant.
Due to the new monitoring server at AIT there weren´t any losses of monitoring data in
summer 2010.
