Abstract
A study on a water-
ow window installed in a test box is presented. This window is
composed of two glass panes separated by a chamber through water
ows. The
ow of
water comes from an isolated tank which contains heat water. In order to fully evaluate
the water-
ow window performance for different room and window sizes, locations and
weather conditions, a mathematical model of the whole box is needed. The proposed
model, in which conduction heat transfer mechanism is the only considered, is one
dimensional and unsteady based upon test box energy balance. The effect of the heat
water tank, which feeds the water-
ow window, is included in the model by means of
a time delay in the source term. Although some previous work about moving
uid
chamber has been developed, air was used as heat transfer
uid and no
uid storage
was considered. Finally a comparison between the numerical solution and the obtained
experimental data is done.
