LEGEND
Length Equiv --- Equivalent tubing length, including effects of refrigeration specialties devices
Typ Linear
--- Typical linear tubing length, Feet (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 100 ft: Minimum 2.0°F subcooling entering TXV
S
Linear Length Greater than 100 ft: 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/0r linear length greater than 125 ft (38 m), contact your local
Bryant representative.
