Recommended capillary tube lengths for each circuit in an air conditioner
evaporator where R-22 is the refrigerant. All recommendations must
be considered approximate, and variations may arise in actual field
applications.
Window air-conditioners normally have one circuit and the recommended
cap tube can be read directly from the chart. Larger air-conditioners
normally have two or more circuits in the evaporator. Where this is the
case, simply divide the total BTU rating of the unit by the number of cap
tube circuits to obtain the BTU/circuit rating of each individual cap tube.
For BTU amounts not on the chart, use the closest number, i.e. for 7900
BTU, use cap tube for 8000 BTU.
The length and I.D. of any cap tube may be adjusted to a more readily
available size by using the R-Line conversion chart in your R-Line
catalogue and on every box of capillary tubing.
Example
Air conditioner is rated at 27,000 BTU and has 3 cap tubes connected to the evaporator. Divide 27,000 by 3 = 9,000 BTU/Circuit. From the
chart, this would call for .075 I.D. (TC-75) 72" long. The length and I.D. of any cap tube may be adjusted to a more readily available size by
using the conversion chart. Figure after the dash in size listed above designate I.D. of tube (i.e. TC-75 = .075).
