Abstract
A test facility for Small SDHW systems was built in 1992. In the
test facility up to 10 SDHW systems can be tested side-by-side
under the same realistic conditions. Since 1992 16 different
systems have been tested in the facility. Both test systems and
marketed systems from Danish as well as foreign manufacturers have
been tested.The thermal performances of the systems have been
measured for periods with a duration of about 1 year. In this way
direct comparisons of the thermal performances of the different
systems are possible.Further, measured and calculated thermal
performances for all the systems have been compared for different
weather periods. Detailed simulation models were used to calculate
the thermal performances. The models were modified in such a way
that good agreement between measurements and calculations were
achieved for different periods.By means of the modified simulation
models the yearly thermal performances of the tested systems have
been determined with the Danish Test Reference Year as the weather
data. Based on calculations with the models improvements of the
design of the different systems have been recommended.Experience
from the operation of the different systems have been gained and
the suitability of different system designs have been
determined.Based on the investigations, recommendations for future
improvements and development of small SDHW systems are given.
