Ice Making Systems
An ice making option may be ordered
with the air-cooled Series R
chiller. The
unit will have two operating modes, ice
making and normal daytime cooling. In
the ice making mode, the air-cooled
Series R
chiller will operate at full
compressor capacity until the return
chilled fluid temperature entering the
evaporator meets the ice making set
point. This ice making setpoint is
manually adjusted on the units
microcomputer. Two input signals are
required to the air-cooled Series R
chiller for the ice making option. The first
is an auto/stop signal for scheduling and
the second is required to switch the unit
in between the ice making mode and
normal daytime operation. The signals
are provided by a remote jobsite building
automation device such as a time clock
or a manual switch. In addition, the
signals may be provided over the twisted
wire pair from a Tracer
system.
