Abstract
In the present study, detailed investigations on evacuated tubular
solar collectors for large solarheating systems have been carried
out. Four types of evacuated tubular solar collectors were used in
theinvestigation. Based on laboratory tests, simulation models for
the collectors were determined. Based on thesemodels, the thermal
performance of large solar domestic hot water (DHW) systems and
combined domestichot water and space heating systems with the four
evacuated tubular collectors was determined. To make acomparison
with traditional flat-plate collectors, similar simulations were
also carried out for systems with atypical flat-plate collector.
The results show that the thermal advantage of evacuated tubular
collectors variesgreatly from system to system, and increases with
the solar fraction. Furthermore, the higher the
operationtemperature of the collector in the system is, the
greater the thermal advantage of evacuated tubular solarcollectors
will be.
