TRNSYS does not contain models of the component parts of an
absorption chiller. Its model of an absorption chiller is a
performance map that gives COP and capacity as a function of the
current inlet conditions of the chilled water, cooling water, and
hot water streams. The TESS HVAC and CoGen libraries contain similar
performance map models for single and double effect steam and direct
fired machines. In order to make a model of an absorption chiller
from first principals, you would have to write models of those
component pieces yourself using a Fortran compiler based on the
information available in the 07-Programmer's Guide manual <br clear="none">
