Performance data
Ratings
Performance Data tables for 30HR fluid-cooled condenser
models appear on pages 21 and 25. Ratings for 30HS con-
denserless models appear on pages 22 and 26. Ratings for
30HS condenserless models in combination with air-cooled
condensers appear on pages 23-24, and 27-28. Ratings
data beyond limits shown and/or brine ratings are available
in Carrier Application Data publications.
1. All performance data is based on:
a. Cooler water temperature rise of 10° F (5.6° C). When
more accuracy is desired, correct LCWT by amount
determined from LCWT Correction curve below be-
fore entering Performance Data tables.
b. Cooler fouling factor of .00025 (.000044) (same for
condenser on 30HR).
c. 10° F (5.6° C) subcooling (30HS).
d. Refrigerant 22.
LCWT CORRECTION
ENGLISH
NOTE: For rise above 10° F, ADD correction to design LCWT; below
10° F, SUBTRACT.
SI
NOTE: For rise above 5.6° C, ADD correction to design LCWT;
below 5.6° C, SUBTRACT.
2. When corrected LCWT is used, cooler pressure drop must
also be corrected for the new LCWT:
a. Enter Performance Data table at corrected LCWT.
By interpolation, determine corrected Capacity (tons
or kW), saturated discharge temperature (in Perfor-
mance Data tables on pages 21 and 25 for 30HS
condenserless units), and kW (compressor motor power
input at rated voltage).
b. Calculate:
corrected capacity (tons) x 24
corrected gpm =
temperature rise (°F)
corrected capacity (kW) x .239
corrected L/s =
temperature rise (°C)
c. Enter Cooler Pressure Drop curve at corrected gpm
(L/s) and find pressure drop.
Where cooler water temperature rise is less than 7° F
(3.9° C), the high flow rate will normally be accom-
plished by excessive pressure drop. In these cases, con-
tact your local Carrier representative for selection of a
cooler with suitable baffle spacing.
Combining 30HS units with remote condensers which
have greater than (less than) the 10° F (5.6° C)
subcooling in the ratings increases (decreases) system
capacity. To adjust capacity, multiply capacity ratings by
0.96; then adjust this result upward by 0.4% for each
degree F (0.7% for each degree C) of available
subcooling.
30HS ARI (Air Conditioning and Refrigeration Institute,
U.S.A.) ratings are based on:
• Leaving chilled water temperature of 44 F (6.7 C).
• Entering cooler water temperature of 54 F (12.2 C).
• Saturated discharge temperature of 120 F (48.9 C).
30HR ARI ratings are based on:
• Leaving chilled water temperature of 44 F (6.7 C).
• Entering cooler water temperature of 54 F (12.2 C).
• Entering condenser water temperature of 85 F
(29.4 C).
• Condenser flow of 3 gpm per ton (0.054 L/s per kW).
