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 1 circuit
and the recommended cap tube can be read directly
from the chart. Larger units have 2 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.
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 inch long.The length and I.D.
of any cap tube may be adjusted to a more readily
available size by using the conversion chart.
