[TRNSYS-users] R: TRNBuild Cooling Load Calculations - Validation In Iran (Tehran)

[Giuseppe Corallo]

Hi,

 

I just checked very quickly your .bui file:  try to increase the
infiltration to at least 1 vol/h; extend the lights load to the entire
floor; include dehumidification with a relative humidity of about 50% and
calculate again.

 

Good luck

Oggetto: [TRNSYS-users] TRNBuild Cooling Load Calculations - Validation In
Iran (Tehran)

 

Dear Sir/Madam

I’m trying to calculate the cooling load for a simple building located in
Tehran, Iran.  The dimensions are 20m*10m*2.5m, with the 20m long façades
face due North-South, as you can see in the attached files. The Maximum
cooling load is obtained to be about 17000kJ/hr or 1.34 USRT which is about
0.007 USTR per square meter. In Iran, HVAC engineers use about 0.03 USRT per
square meter for Tehran’s cooling load as a rule of thumb, which is about 4
times the result obtained from TRNBuild. 

Please kindly help me with the issue, since TRNBuild is not used for
cooling/heating load calculations in Iran and I’m trying to present it as a
useful tool. Your assistance could be very decisive.

Best Regards

Hooman Azad
