Refrigerant Pressure Sensor / Switch: Description and Operation
The refrigerant pressure sensor measures the refrigerant pressure and transfers it to the automatic A/C pushbutton control module.
The refrigerant pressure sensor measures the refrigerant pressure and transfers the value measured to the automatic A/C pushbutton control module Via
the left signal acquisition and actuation module and the CAN bus. This value is compared with a stored temperature/pressure curve. The refrigerant
pressure sensor operates within the range of 0 to 35 bar.
Switching off the A/C compressor
The A/C compressor is switched off at the following values:
- Refrigerant pressure < 1.75 bar A/C compressor off
- Refrigerant pressure > 30 bar A/C compressor off
Switching on the electric engine/A/C electric fan
The engine/A/C electric fan is switched on at the following values:
- Refrigerant pressure < 12 bar
- fan off
- Refrigerant pressure > 20 bar
- fan on (100%)
- Refrigerant pressure 12 bar to 20 bar
- Infinite linear increase in fan speed (40 - 100 %).
