Open Network Integration
Daikin has released interfaces for use in BACnet, LonWorks
and Modbus networks equipment and building control
systems. BACnet, LonWorks and Modbus
networks are
recognised worldwide as the de facto standard within
the building controls industry. BACnet, LonWorks and
Modbus data communication protocols make it possible
to control access, energy management, fire/life/safety,
HVAC and lighting etc.
Simultaneous operation of up to 5 chillers is optional
through EKCSCII sequencing panel (this function enables
a Daikin 9MW chiller plant to be operated via a single
controller).

COmpRESSOR
The large Daikin chillers are fitted with a single screw
compressor with stepless capacity control. The stepless
capacity control enables the requirements to be closely
matched by modulating the sliding valve position according
to the chilled water control condition. Capacity control is
infinitely variable between 25 and 100 % on single circuit
units and between 12.5 and 100 % on dual circuit units.
Main advantages of continuous modulation are better part
load efficiency and more stable chilled water temperatures
with closer control tolerance.
Shell & tube condenser*
Special header distribution system and design of water
system result in high efficiency and reduced heat
transfer surface
Compact dimensions and lower weight result in a
smaller refrigerant volume
