Air Conditioning: Overview
WARNING: This page is about a different car, the 2018 Land Rover Discovery and 2017 Land Rover Discovery. However, it is still accessible from the selected car via links, so may be relevant.
The Air Conditioning (A/C) system is a sealed, closed loop system filled with a charge weight of refrigerant as the heat transfer medium. Oil is added to the refrigerant to lubricate the internal components of the A/C compressor. The system consists of:
- An A/C compressor
- An A/C condenser
- A receiver drier
- A Thermostatic Expansion Valve (TXV)
- An evaporator
- Low and High Pressure refrigerant lines
- A refrigerant pressure sensor.
A pressure sensor in the high pressure refrigerant line allows the Automatic Temperature Control Module (ATCM) to monitor the status of the A/C system. For additional information, refer to: CONTROL COMPONENTS .
