[TRNSYS-users] Data center electrical supply heat gain simulation

[David BRADLEY]

Johnson,
   Apologies for the delay in responding. There are a number of generic 
models in TRNSYS that would suit your needs (such as Type42, or even a 
simple equation). The difficulty that you face is in obtaining realistic 
information from the manufacturer of the transformers, UPS, and PDU. 
They should be able to give you some information about the heat 
generated by their equipment under normal operating conditions, 
including standby mode which you will need when the data center is 
running at part load (incidentally, I have never seen this situation! 
Data centers that I have run across basically use the same amount of 
energy and dump the same amount of heat into the space all the time!)

   Once you obtain the performance and efficiency of the equipment at 
part load then you need to add a gain to the Type56 zone that represents 
your data center. You can specify the gain either as a schedule in 
TRNBuild or as an input.
Best,
  David
