Notes:

  • Refer to DuPont Refrigerant Expert, Version 2.0 for actual velocities and pressure drops.
  • Equivalent length is actual length plus friction losses caused by fittings and accessories.
  • Line sizes are expressed in outside diameter of type “L” copper tubing.
  • Line sizes are calculated at rated full load system capacity.
  • All selections are based on a maximum of 65°F return gas entering the compressor and refrigerant condensing and liquid line temperature of 105°F.
