Discharge line pressure drop should not exceed 9 PSI (62 kPa) for R-410A. Recommended gas velocity
for proper oil return is 1,000 FPM (5.1 m/sec). Slope horizontal lines downward in the direction of the
refrigerant flow. The recommended slope is 1/2” (12 mm) for every ten (10) feet (3 m) of line length.
Discharge lines do not require insulation but due to the high temperatures of the refrigerant inside the
line, the pipes may be insulated to protect against burns to individuals near or around the lines.
Liquid Lines
Liquid line size is determined by pressure drop and velocity. The liquid line pressure drop should not
exceed 9 PSI (62 kPa) for R-410A. The recommended liquid velocity should be between 200 and 300
FPM (1 to 1.5 m/sec). To avoid excessive liquid line pressure drop, the air-cooled condenser should be
located above or at the same level as the evaporator. Condenser installations more than 15 feet (4.6
m) below the evaporator are not recommended. Insulation of liquid lines is not required but can be
useful in preventing excessive sub-cooling or flashing on long exposed pipe runs.
