[TRNSYS-users] Cooling load or total heat transfer rate

[David BRADLEY]

Safwan,
  There is a very important difference between a building cooling load 
and the total heat transfer rate being computed by Type697. A building 
total cooling load is the amount of energy (sensible and latent) that 
must be removed from a space in order to maintain a setpoint. Type697 is 
reporting the amount of energy that it actually removed from the air 
stream. If Type697 isn't maintaining the setpoints that you want it to 
then the amount of energy that it is removing from the space and the 
building's cooling load are not going to be equivalent.
  I would recommend that you go through the tutorial called "Temperature 
Level Control from Energy Rate Control" that can be downloaded from: 
http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/tutex17.htm. 
The tutorial should answer your questions about the how to obtain the 
loads or the energy transferred by the system.
regards,
  David
