Example
System 1: Chiller and Condenser Loops[LINK]
A simple cooling system will be used as an example to
demonstrate the process of inputting a system into the input
file. The input file for this example can be found under the
name: PlantApplicationsGuide_Example1.idf.
This particular system consists of two unique
sub-systems/loops. It contains the PlantLoop
with the chiller and the load profile, and another PlantLoop
with the cooling tower. A schedule containing previously
obtained simulation loads is used to simulate the demand load
profile for this loop (Note: In a more general scenario a
cooling coil placed in a building zone would provide the load
profile). Flow diagrams along with some keywords from the
input file will be used to record to steps that are required
to properly input the system into EnergyPlus. The simple line
diagram for this system is provided in Figure 1.1.
The complete EnergyPlus schematic for the system is provided
in Figure 1.2.

The cooling system consists of a chilled water loop which
is defined by the PlantLoop
object, and a condenser loop which is also defined by the
PlantLoop
object. Identification of these loops in the system is
critical for the process of modeling the system in the input
file the flowchart for loop identification is provided in
Figure 1.3.
