Air conditioning simulation

sharonyue · July 16, 2015, 03:09

Hello guys,

Im not the expert on HVAC. I have a small confusion about air conditioning simulations.

As we know I have two options:

1. Use buoyantBoussinesqFoam;
2. Implement TEqn into piso/simpleFoam;

I know that when the cooling air was injected into the closed house. Most of the temperature changes come from "the cooling air was injected into it".

So I think the buoyant force might be neglected(also gravity). I mean this is not to simulate hot room heated by a hot steel(buoyant force is a must).

So do u think I can choose method 2 to simulate air conditioning system?
Best,

Hi,

in your case use buoyantBoussinesqSimpleFoam.

Bye
