Delay In Connection With Defrost - Danfoss ADAP-KOOL AKC 114 G Mode D'emploi

AKC 114G

Delay in connection with defrost.

a. Liquid injection
When the defrost sequence starts, the injection stops and the refrigerant (5) is emptied out
of the evaporator before liquid injection is resumed (6).
The times of the three functions are set, as follows.
The time delay is set in minutes (0 min., if applicable).

b. Fan start (7)
Drops of water left on an evaporator after defrost should be bound to the evaporator
(primarily used in freezing rooms).
After defrost, the liquid injection is started, the evaporator is cooled down, but the fans will
be started a little later. During this period the controllers operate the expansion valve by
force, but they constantly monitor the superheat.
The temperature at which the fans are to be started is set (measured always with the S5
sensors). The max. permissible time delay in minutes is set.
The time delay for fan start will not commence until the time delay for liquid injection, if
applicable, has run out.
If S5 register a lower temperature than the set by the delay time has elapsed, the fans will
start. At the same time alarm is given that Maximum delaytime for fan is exceeded. If the
alarm is not acknowledged within five minutes, it will automatically be cancelled.
If the S5 sensor is defective, the signal from sensors that remain intact will be used.
The time delay is set in minutes (0 min., if applicable).
