[TRNSYS-users] how to connect building cooling load to absorption chiller

[David BRADLEY]

Amadu,
   The way I have approached this is to use the "loads imposed on a 
liquid stream" component from the TESS Loads and Structures library 
(Type682). The same can be accomplished with an equation: Tout = Tin + 
QLOAD/mdot/Cp where Tin is the temperature of liquid being supplied by 
the absorption chiller, QLOAD is the building cooling load, mdot is the 
mass flow rate of liquid supplied by the absorption chiller, and Cp is 
the specific heat of the liquid. I would advise also putting a pump, 
piping, and a storage tank large enough to hold the volume of liquid 
that the pump puts out in one timestep. Make sure also that you are 
using a reasonably small timestep such as 5 minutes.

  As for Type107 data, this is unfortunately somewhat hard to find. I 
would recommend searching manufacturer's websites (Carrier, York, etc.) 
for performance data on a specific machine that you want to model.
Kind regards,
  David
