Capacity, GPM and Pressure Drop Data for 15°F Range R22
Catalog units presented above are designed for the listed ratings. Higher capacities may be possible with different baffle spacing's. Contact Factory.
The capacity data table above is based on R12 with water
range at 8°F and approach at 7-12°F.
Sizing
—To select the direct expansion chiller you must know:
1. Capacity at maximum load in thousands of BTU/HR (MBH)
[Capacity BTU/HR = GPM X RANGE X 500]
2. Water cooling range °F: inlet water temperature
minus
outlet water temperature.
3. Approach temperature °F: outlet water temperature
minus
refrigerant evaporating temperature.
The final selection may depend on the water side pressure drop
(psi), at the full GPM flow rate, being within acceptable limits.
See example below.
DUTY
SELECTION
64 GPM water
Range: (55-43) = 15°F Approach (43-33) = 7°F
Entering water temperature: 55°F
Capacity 64 GPM x 15° x 500 = 480 MBH
Leaving water temperature: 40°F
From above table, select EM050; maximum capacity
Refrigerant evaporating temperature: 33°F
483 MBH, requiring 64.2 GPM water with 2.2 PSI
Single Circuit
pressure drop: Model EM050-10072-1.
Nominal Ratings
in tons refrigeration (Nom Tons) are based on:
54°F entering water minus 44°F leaving water (10° range)
35°F evaporating temperature (9° approach)
100°F entering liquid refrigerant with 7°F suction superheat
0.00005 fouling factor
Limitations
Minimum evaporating temperature ……………………………32°F
Maximum water entering temperature ………………………..75°F
The listed water chillers are designed for the ranges and
approach temperatures in the tables. Consult factory for
selections at different conditions.
