Defrost procedure will never be executed if Ta > 7 °C (adjustable under maintenance
password).
Defrost procedure will never be executed if Ts > 0 °C (adjustable under maintenance
password).
During defrost the circuit are switched in “cooling mode” for an adjustable time (default 10
min) if Ta < 2 °C (adjustable under maintenance password), otherwise the compressor are stopped
and fans are kept at maximum speed for another adjustable time (default 15 min).
Defrost procedure are stopped if evaporator outlet temperature fall below a set value or if
discharge pressure reaches a set value.
During defrost procedure “Low pressure switch alarm” and “Low suction pressure alarm”
are disabled.
If the switch in “cooling mode” is required, it are executed only if the pressure difference
between compressor discharge and suction exceeds 4 bar; if this isn’t the compressor are loaded to
reach such a condition. After the switching compressor fans are switched off and a pre-purge
procedure are executed (at minimum compressor load) . After prepurge the compressor are loaded
energizing the loading solenoid with an adjustable number of pulse (default 3).
At the end of defrost procedure executed in “cooling mode” compressor are switched off
after its complete download without execution of pumpdown; than the 4-way valve are
deenergized; than the compressor are available for temperature control system ignoring the start to
start timer.
6.15. Liquid injection
Liquid injection in the discharge line is activated both in cooling/ice and heating mode if the
discharge temperature exceeds an adjustable value (default 85°C).
Liquid injection in the suction line are activated, only in heating mode, if the discharge
superheat exceeds an adjustable value (default 35°C).
6.16. Heat Recovery procedure
The heat recovery procedure is available only in units configured as chillers (not available
for heat pumps).
The manufacturer will select the circuits equipped with heat recovers.
6.16.1.
Recovery pump
When heat recovery is activated the control will start the recovery pump (if the second pump
is foreseen the pump with low operating hours is selected, a manual pump sequencing is foreseen);
within 30 sec a recovery flow switch must close otherwise and “Recovery Flow Alarm” will rise
and the heat recovery function is disabled; the alarm is automatically reset for three times if the
evaporator flow switch closes for more than 30 seconds. Starting from the fourth alarm it has to be
reset manually.
No recovery circuit must be activated if a flow switch alarm occurs.
