On VARIABLE capacity compressors the suction
level can be adapted depending on the thermal
needs:
g
To provide the appropriate comfort
g
To consume the optimum energy and reduce fuel
consumption
The suction pressure level is set to the appropriate
level and limited to 3 bars.

On FIXED capacity compressors the suction level can
NOT be adapted.
It is mandatory to monitor the evaporator temperature
and stop the compressor immediately before freezing
occurs; this is the role of the evaporator sensor, the
compressor is then disabled via the electromagnetic
clutch pulley.
