[TRNSYS-users] Behaviour of water pipes

[Xavier Dequaire]

HI all,

I wonder if I can easily make a model of the following configuration:
a water system for a residential building
with DHW
A tank for DHW at given temperature
(further developement is thermosyphon solar heater on roof)
Hot water pipe
Cold water pipe
Place of use and mixing

The idea is to compare
different piping lay-outs
the impact of the distance from storage to use( length of pipes)
the impact of pipe insulation

The backgroung is the obvious discomfort to get hot water delivered at
first outdoor temperature, then maximum tank temperature around 70-80C,
then mixit etc.. and the thermal losses related ( in a low energy
building, the DHW energy consumption gets a high % of total energy
consumption)

Any hint experience out there?

thank you

Xavier
