IEA SHC Task 38 Solar Air Conditioning and Refrigeration Subtask A Report A-D3b, Date: December 2010
1 Introduction
This report summarizes the monitoring activities on small-scale solar heating and cooling
systems carried out within subtask A of IEA-SHC Task 38. All systems were monitored
according to the monitoring procedure developed with Task 38. However, the level of detail
varies from system to system. The monthly monitoring data has been filled into the
Monitoring Excel Tool of Task 38.
In the first part of the report, a short description of all 13 systems that were monitored is
given including the characteristic data of the application and the installation, a few pictures
and a short written summary of the monitoring results.
In the second part, an overview of the key performance figures of 11 of the systems is given
and the results are compared with each other (For 2 systems there were not enough reliable
data available to include them in the comparison). The shown performance figures include
different coefficients of performance of the chillers and the whole systems as well as the
reached fractional primary energy savings, the collector yields and the water consumption of
the cooling towers.
Finally, for most systems, there is a more detailed report on the monitoring results available
in the appendix.
