chiller

Kind:	Marker
Used With:	equip

Chillers remove heat from a liquid via a vapor compression or an absorption refrigeration cycle.

From: Chillers | Chillers

Chiller equips are marked with the chiller tag. Equip level tags:

• equipRef must reference parent chilledWaterPlant if associated with a plant
• waterCooled or airCooled
• absorption or if vapor compression: reciprocal, screw, or centrifugal
• coolingCapacity

Points associated with chiller equip:

Run/Status

• run cmd
• run sensor
• enable cmd
• load cmd
• load sensor

• chilled water leaving temp sp
• chilled water leaving flow sensor
• chilled water leaving pressure sensor
• chilled water entering temp sensor
• chilled water entering flow sensor
• chilled water entering pressure sensor
• chilled water delta temp sensor

Condenser water to/from cooling towers

• condenser water leaving temp sensor
• condenser water leaving flow sensor
• condenser water leaving pressure sensor
• condenser water entering temp sensor

Misc Internal

• condenser cmd
• condenser refrig temp sensor
• condenser refrig pressure sensor
• evaporator refrig temp sensor

Note: not every combination of sp is listed, just most common setpoints. Chillers share the same point modeling conventions as VFDs. Chillers which measure energy should model their points using the same conventions as elec meters or thermal meters.
