Peak temperature

Hi,

I am simulating the maximum temperature achieved in a room given the cooling loads and the system maximum cooling output.

The maximum temperature I get is 31'C, however this would happen at 8am which is outside the occupied times. Therefore, it is not very relevant for the project.

Is there a way I can get the synopsis table for the occupied times only and 'forget' what happens outside the occupied times?

(I have made an example for one room, however this actually applies for much more rooms, hence I am looking for a systemic solution. I would prefer not to have to check the peak temperature graph for each room)


Thanks.

Hi,

I would say your best bet is to use VistaPro to make a custom variable for "temperature when occupied".

So guidance on this here:

Hi Ste,

As Ross mentioned the value you are after can be obtained using Custom Variables.

The mean can be calculated using:

Code: Select all

AVG(IF(B>0,A,NAN))
The minimum can be calculated using:

Code: Select all

MIN(IF(B>0,A,INF))
and the maximum can be calculated using:

Code: Select all

MAX(IF(B>0,A,-INF))
Where A is 'Air temperature' and B is 'Number of people'.

I hope this helps,
John
