Prof Flarend,
There is a swimming pool model available from Transsolar. While it takes
into account the heat and mass transfer from the surface and would be
able to act as the energy sink from a heat pump, it doesn't allow for
the freeze/thaw of the surface and it assumes that the water is fully
mixed. I would think that in your application, you would need to account
for the thermocline so that the top can freeze while allowing the bottom
to stay liquid. The pool model might be a good place to start if you
need to deal with a freeze/thaw cycle. If the pond is going to have a
layer of ice on it throughout your simulation I would guess that it
would be just as easy to write a model from scratch.
Best,
David

It would need to take into account the freezing of the surface and the changing albedo that comes with that. Our school has a man-made pond that some students want to investigate as a heat sink while at the same time also providing a skating rink.
