Chillers

Chillers provide chilled water to cooling coils, chilled beams and cooled ceilings. They can be placed using the Add Chiller command when you are located in a Chilled water supply loop.

When using Detailed HVAC, to edit an existing chiller go to the Chilled water supply loop (HVAC System > Chilled water loop > Supply loop) level where the chiller is placed, click on the chiller icon to highlight it then either right click and select the Edit selected component menu option or, when using Learning mode, click on the Edit icon in at the top of the info panel.

These chiller types are available:

• 1-Constant CoP - a simple model with constant efficiency and no performance curves.
• Chiller - EIR - a more detailed model using 3 performance curves to determine cooling capacity and CoP from the chiller load and outside air temperature.
• 3-Reformulated EIR - an empirical model similar to the Chiller EIR model.
• 4-Absorption - the basic absorption chiller model.
• 5-Indirect absorption -a more advanced absorption chiller model with more flexible performance curves and ability to model the effect of varying evaporator, condenser, and generator temperatures.
