High-Pressure Regulation - Tecumseh INFINEE Manuel D'utilisation

4.3.2. High-pressure regulation:

Condensation pressure regulation is carried out through:
•
Speed variation of the condenser fans:
Fan start-up is set by a threshold on the condensation pressure measurement, with the ventilation
speed proportional to the condensation pressure measurement.
The condensation pressure control setpoint can be fixed or based on a floating HP principle.
•
Speed variation of the compressor:
A PID-type control loop controls the condensation pressure.
This control loop limits the speed of the compressor to avoid reaching the safeguards, in case of
operation in extreme conditions, and in order to guarantee the operation of the installation.
