Table 2 — Refrigerant Line Sizes for 30HXA Chiller/09DK Condenser Combinations — Recommended
Refrigerant Pipe Sizes (in. OD)
LEGEND
OD — Outside Diameter
*Field-supplied liquid line solenoid valve is required.
†Double discharge riser is required on ALL units which have minimum
load control installed. See Table 3.
NOTES:
1. Refrigerant and Double Discharge Riser Pipe Sizes tables are
based on equal chiller and 09DK condenser sizes — i.e.,
30HXA096 with 09DK094.
2. For other system combinations, size lines per ASHRAE (American
Society of Heating, Refrigerating, and Air Conditioning Engineers)
or other R-134a line sizing guides such as the System Design
Manual, Part 3, or the E20-II
®
Software Refrigerant Piping program,
for proper piping sizes and design.
3. Refrigerant and Double Discharge Riser Pipe Sizes tables are
based on cooler leaving water temperatures of 40 F (4.4 C) or
above. When cooler temperature is below 40 F (4.4 C), use the
information in Fig. 15 and 16 for pipe sizing.
4. Pipe diameter calculation is based on actual line length plus a 50%
allowance for fittings.
5. For proper electronic expansion valve (EXV) operation, discharge
line losses should not exceed 4° F (-15.6° C) at full load. A calcula-
tion of line loss should be performed prior to installation.
