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



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

Dear All,

I am simulating solar cooling system, shall I depend on total heat transfer rate output from Type 697( cooling coil) as a cooling load for building or not? If not shall I need to calculate the cooling load for building by Trnsys? if yes ,could you please explain HOW in details? I used Type 56.

I am looking forward to hearing from you.
