Legend:
Equivalent Length
Equivalent tubing length, including effects of refrigeration specialties devices
Linear Length
Typical linear tubing length (50% added to linear to define Equivalent Length for this table)
Liquid Line
Tubing size, inches OD.
Max Lift
Maximum liquid lift (indoor unit ABOVE outdoor unit only), at maximum permitted liquid line pressure drop —
S
Linear Length Less than 75 ft (23 m): Minimum 2.0° F subcooling entering TXV
S
Linear Length Greater than 75 ft (23m): Minimum 0.5° F subcooling entering TXV
Suction Line
Tube size, inches OD
Charge
Charge Quantity, lbs. Calculated for both liquid line sizes (where applicable), but only with larger suction line size (where applicable)
NOTE:
For applications with equivalent length greater than 188 ft (57 m) and/or linear length greater than 125 ft (38 m), contact your local
Bryant representative.
