8. Refrigerant Line with Inner Heat Exchanger
   • Overview. Refer to OVERVIEW - INTERIOR HEAT EXCHANGER, REFRIGERANT LINES IN PLENUM CHAMBER AND EXPANSION VALVE .
   • In this refrigerant line, the liquid warm refrigerant flowing on the high pressure side releases energy into the vaporous cold refrigerant flowing on the low pressure side. This increases the efficiency of the A/C system.
   • Removing and Installing. Refer to REFRIGERANT LINES WITH INNER HEAT EXCHANGER, REMOVING AND INSTALLING .
