Thanks for your answer.
I need more explains.
1
What do you mean with "very low resistance value" ?
Can you give me a value ?
I don't know what are the differences between a massless layer and a massive layer.
I always work with massive layer !
Could you explain me ?
2
How do you coupling exchanges ?
It seems to me I must give 5 inputs to the type 56 :
- Temperature of pool water
- Heat flow rate by Convection
- Heat flow rate by Long-wave radiation
- Mass flow rate of Evaporation
- Heat flow rate by Evaporation
Can you help me for the coupling ?
3
I don't know which value to connect to the input 4 of the type 144 (Total Solar Radiation on a Horizontal Surface)
In the tutorial, I can read 2 differents things :
- "The short-wave thermal gain for an indoor pool have to be determined differently. When this Type is combined with type 56, the solar gain striking at the pool surface can be determined and used." (Basic physical principles)
- "not used for an indoor pool" (Description of inputs)
So, What the solution ?
4
For the input 5 : Temperature of the sky, Is it necessary for an inddor pool ?
5
For the input 7 : Short-wave radiation gain. The tutorial said to use Ntype 21 (QABSI) of the type 56. Do you know how this Ntype is calculated ?
Best regards.

Fabien,
I'm not sure if I understood completely your problem. However I would not model the pool by a zone but I would try to model the coupling between pool and zone by a massless boundary wall with very low resistance but with coupling temperature of the pool and an air/humidity exchange given by the evaporation mass flow.
Hello everybody,
I have bought the type 344 of TRANSSOLAR.
In first, I have create a surface of water to consider the exchanges between the pool and the building.
But the thickness is limited (0.39 [m] otherwise I have an error (creating wall transfert function ...).
I would like to know if I must create a zone for the pool in changing the capacitance (water instead of air !).
Thanks to that, I could create a heating schedule of the water.
But I don't know how I must declare the surface of exchange between the pool and the building.
Anyone knows what I should do ?
Maybe anyone have an example ?
Thanks.
