Notes:

  1. Table capacities are in tons of refrigeration.
    Triangle Symbol p = pressure drop due to line friction, psi per 100 ft of equivalent line length
    Triangle Symbol t = corresponding change in saturation temperature °F per 100 ft
  2. Line capacity for other saturation temperature Triangle Symbol t and equivalent lengths Le
    Line Capacity = Table Capacity [ Table Le X Actual Triangle Symbol t ] 0.55
    _____ _____
    Actual L Table Triangle Symbol t
  3. Saturation temperature Triangle Symbol t for other capacities and equivalent lengths
    Triangle Symbol t Table Triangle Symbol t [ Table Le X Actual Capacity ] 1.8

  4. Values in the table at the right are based on 105°F condensing temperature. Multiply table capacities by the following factors for other condensing temperatures.
Condensing
Temperature, °F		 Suction
Line		 Discharge Line
80 1.158 0.804
90 1.095 0.882
100 1.032 0.961
110 0.968 1.026
120 0.902 1.078
130 0.902 1.156

a The sizing shown is recommended where any gas generated in the receiver must return up the condensate line to the condenser without restricting condensate flow. Water-cooled condensers, where the receiver ambient temperature may be higher than the refrigerant condensing temperature, fall into this category.

b The line pressure drop Triangle Symbol p is conservative; if subcooling is substantial or the line is short, a smaller size line may be used. Applications with very little subcooling or very long lines may require a larger line.
