High Evaporator Shell Refrigerant

High Evap Shell Rfgt Pressure - Ckt1
High Evap Shell Press Ckt1

Chiller Immediate

NonLatch

All

The evaporator shell refrigerant pressure 
is installed, is valid, and has risen above 
190 psig.
- De-energize evaporator water pump 
regardless of why the pump is running.
- Open the circuit’s EXV to 20% to allow 
refrigerant flow to other parts of the chiller, 
if liquid line refrigerant pressure is less 
than 170 psig. Return EXV to normal 
control (allow it to close until needed for 
circuit operation) if liquid line refrigerant 
pressure is greater than 175 psig.
Automatically clear diagnostic when 
evaporator shell refrigerant pressure is 
valid and drops below 180 psig.
- Allow evaporator water pump to return to 
normal control.
- Return circuit’s EXV to normal control 
(allow it to close until needed for circuit 
operation).
Primary causes of this diagnostic:
- Evaporator water pump heat transferred 
to evaporator, either by flow blockage, or 
by lack of heat dissipation in the water loop 
in the presence of flow.
- Commissioning unit in high ambient 
temperature environments.
- Water box heater thermostat failed 
closed.

diagnostic is

Either the leaving or the entering water 
temperature exceeded the high evap 
water temp limit (TU service menu 
settable –default 105F(65.55C), range 
80F(26.67C)-150F(65.55C) for 15 
continuous seconds. The evaporator water 
pump relay will be de-energized to stop 
the pump but only if it is running due one 
of the diagnostics listed on the left. The 
diagnostic will auto reset and the pump will 
return to normal control when both the 
entering and leaving temperatures fall 5°F 
below the trip setting. The primary 
purpose is to stop the evaporator water 
pump and its associated pump heat from 
causing excessive waterside temperatures 
and waterside pressures when the chiller is 
not running but the evap pump is on due 
to either Evap Water Flow Overdue, 
Evaporator Water Flow Loss, or Low Evap 
Temp – Unit Off Diagnostics. This 
diagnostic will not auto clear solely due to 
the clearing of the enabling diagnostic.
