Cooling plant
Chillers, pumps and cooling towers make and move chilled water. 21 device types.
Absorption chiller
Lithium-bromide chiller driven by steam, hot water or a burner, often on waste heat. Crystallization and loss of vacuum are the main risks.

Ice storage
Glycol builds ice at night and melts it by day; ice inventory and glycol temperatures decide peak shaving.
Protocols: BACnet/IP · Modbus TCP · OPC UA
Used in: Commercial buildings · Healthcare
4 brands: BAC, CALMAC, Cryogel, Huadian Storage
Large centrifugal chiller
Thousand-ton central-plant chillers serving air handlers and process cooling water exchangers. N+1: when one trips the standby must come on line quickly.
