Hi Arianna,


Use high zone time step (for example 10) or above this will improve the results especially with PCM's modelling.

Regards.

Dear All, 
 
I am trying to use phase change materials, phase change plasterboard, via the active components. I am using a melting temperature of 26°C and a solidification temperature of 27°C. I am not sure about the solidification temperature and I would like to know if some of you can advise on this. I am trying to have the PCM exposed, so I always position it on the internal layer as I suppose when the software asks for the position it starts counting the existing layers from the exterior. 
 
However I try, I can’t see any substantial reduction in the indoor temperature during a hot summer month. Can any of you give some advice on how to reduce the indoor temperature further by changing the parameters? 
 
Thank you in advance,
 
Best regards,
 
Arianna
