Refrigerant Line With Inner Heat EXCHANGER
WARNING: This page is about a different car, the 2022 Volkswagen ID.4 and 2021 Volkswagen ID.4. However, it is still accessible from the selected car via links, so may be relevant.
Vehicle-Specific
- In this refrigerant line, the liquid or vaporous warm or hot refrigerant flowing on the high-pressure side releases energy to the gaseous or vaporous cold refrigerant flowing on the low-pressure side. This increases the cooling efficiency of the A/C system as well as liquefies any existing vaporous refrigerant.
A - Refrigerant line with inner heat exchanger
B - Channel in the refrigerant line, in which the liquid or vaporous warm/hot refrigerant flows to the expansion valve (refrigerant circuit high-pressure side).
C - Channel in the refrigerant line, in which the gaseous or vaporous cold refrigerant flows to the A/C compressor (refrigerant circuit low-pressure side)
- The inner heat exchanger is always installed in the refrigerant circuit downstream of the accumulator. Refer to Refrigerant Circuit (vehicle-specific Service Information).
