Internal Heat Exchange Tube Line (IHX)

Internal Heat Exchange Tube Line (IHX)
  • The IHX is mainly applied on the R1234yf refrigerant system to increase the energy efficiency
  • The conventional design of liquid and suction lines are arranged in separate pipes (top left picture)
  • The IHX consists of a double layer pipe (a tube in a tube)
  • The cool vapor from the evaporator cools down the hot liquid line improving the system efficiency
  • Today, the IHX is widely used on the R1234yf new refrigerant system
