We have an unusual project (for our company). Our client wish to use a large warehouse space and create rooms within the space up to around 4 meters high. 4 Pipe fan coils units will then be installed at this height to force air down into each space (whether it be heating r cooling). However, these rooms do not have ceiling and the space above is completely open, up to the 10m high exposed roof.
We have created the model and all appears to be OK, however when you select the heat loss tab and select your heating system as warm air forced down from h/l, what height does Hevacomp apply to the heat being forced down into the space? This will have a huge bearing on the required load if Hevacomp uses the full height of the space as opposed to the partition height.
Hevacomp states the rooms are 10m high when reviewing the room tabs in CAD Input (exposed roof height), is this the height used and if so is there a way of modifying this height to suit our application?
Kind Regards,
Dan
Hi Dan,
As this does indeed sound like quite an unusual building I think I would need to take a look at your model before I could offer specific advice - could you please zip the project folder and upload to this link?

Thanks Dan, I have been inspecting the project and I will contact you privately via email shortly to discuss further.
