Water System Flow Rates
Establish a balanced chilled water flow through the
evaporator.The flow rates should fall between the
minimum and maximum values. Chilled water flow rates
below the minimum values will result in laminar flow,
which reduces heat transfer and causes either loss of EXV
control or repeated nuisance, low temperature cutouts.
Flow rates that are too high can cause tube erosion.
The flow rates through the condenser must also be
balanced.The flow rates should fall between the minimum
and maximum values.
Water System Pressure Drop
Measure water pressure drop through the evaporator and
condenser at the field-installed pressure taps on the
system water piping. Use the same gauge for each
measurement. Do not include valves, strainers fittings in
the pressure drop readings.
Pressure drop readings should be approximately those
shown in the Pressure Drop Charts starting with Figure 21,
p. 43.
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
NOTICE:
Equipment Damage!
Ensure that the oil separator and compressor heaters
have been operating for a minimum of 24 hours before
starting. Failure to do so may result in equipment
damage.
