Refrigeration
The refrigeration cycle is analyzed through the
graph on the right side where it is possible to see
under which operation conditions the system
activates the refrigeration (compressor).
The parameter must be set to count the number
of ignition starts. When this number is reached,
the refrigeration system is forced to be on for 2
minutes. After this time it elapses, the system
goes back to normal operation and the counter
of ignition starts is reset and starts a new counting.
The system components operate according to what is described below:
Compressor:
The compressor is activated in accordance with the temperature, the pressure switches and the
programmed values at the Set-point and the parameters.
The compressor will just turn on 10 seconds after the condenser motors are turned on.
The controller presents a time hysteresis fixed at 60 seconds for turning the compressor back on, that is,
the compressor will be kept off for a minimum time of 60 seconds before being turned on again
Fans – condenser motors:
The fans will turn on every time there is the need to turn on the compressor. They will always turn on 10
seconds before turning the compressor clutch on.
