Abstract
Abstract It is important to avoid condensation in solar
collectors, most of all because wetness of the absorber can damage
the selective surface and cause corrosion on the absorber plate.
During night time the cover of collectors will cool below ambient
temperature due to thermal radiation to the cold sky. In climates
where the air during night time becomes saturated with humidity
(the relative humidity is 100%), condensation will form on the
outside and inside of the collector glazing. If too much
condensation takes place on the inside of the glazing, it will
start to fall off on to the absorber surface. It is important to
characterize microclimatic conditions in the collector, and at the
Department of Buildings and Energy work is carried out with the
improvement of a computer model. As a tool the computer model will
be useful in developing guidelines to achieve the most favourable
microclimate conditions for materials. Results from the computer
model will be compared to measurement of microclimatic parameters
in a collector in operation.
