Based on AHRI standard percentage ratio point.
NOTES:
1. Capacity is based on pure water. For performance using Glycol Solution, see Adjustment Factor on Page 9.
2. All full-load performance data is based on a 10°F chilled-water temperature drop
through the evaporator.
3. Fan and controls kW are included in tabular kW data.
4. For total chiller performance, multiply above output (Tons) and input (kW) by the
number of modules.
5. Leaving water temps below 40° requires freeze protection.
6. Based on 0.0001 fouling water for the evaporator.
7. Following ARI 550/590 Standard 29.92 inches mercury barometric pressure is
used for the data basis.

Selection Data
SELECTION
To select an AIRSTACK Air Cooled chiller, the following
information is required.
1. Load (in tons) of refrigeration.
2. Chilled-water temperature drop.
3. Leaving chilled-water temperature.
4. Design ambient-air temperature.
CAPACITY TABLES
Capacity tables are based on a 10°F temperature drop
through the evaporator. For other than a 10°F temperature
drop, apply the respective performance adjustment factors
from Figure 1.
EVAPORATOR WATER FLOW RATE
Evaporator water flow is determined as follows:
gpm = (24) (tons) / temperature drop
WATERSIDE PRESSURE DROP
Evaporator waterside pressure drops are provided in
Figure 2. To use Figure 2, divide the total chilled-water gpm
by the number of modules in the chiller.
CHILLED-WATER SELECTION SAMPLE
(Assumes ASP-15 Modules)
1. System load = 55 tons. Chilled-water drop at 12°F.
2. Leaving chilled-water temperature of 45°F. Design ambient-air
temperature of 95°F.
3. Use the Figure 1 adjustment factor to convert tons at 12°F to
equivalent tons at 10°F for use with capacity tables.
Tons = 55/1.012 = 54.3 tons
4. Select the appropriate performance table based on the module to
be used. Read the capacity and kW of a single module at the water
temperature specified (45°F) and design ambient-air temperature
(95°F). capacity = 14.4 tons, kW = 15.8
Divide the equivalent tons required at 10°F temperature drop by the
single module capacity from the tables.
Modules required = 54.3/14.4 = 3.8 modules
Chiller capacity = 14.4 x 4 = 57.6 tons
Power input = 15.8 x 4 = 63.2 kW at 12°F temperature drop; applying
the Figure 1 performance adjustment factor results in: tons = (57.6)
(1.012) = 58.3 vs. system load of 55 tons.
5. To determine the evaporator water flow and pressure drop, first
determine gpm.
gpm = (24)(54.3)/12=108.6
gpm/module = 108.6/4 = 27.2
From Figure 2, read pressure drop from curve C pressure drop = 2.4 ft.
of water.

LOW-TEMPERATURE OPERATION WITH GLYCOL
(Assumes ASP-15 Modules)
Ethylene Glycol adjustment factors (Figure 3) should be used to adjust
performance depending on the percent of glycol use in the evaporator
circuit. The factors in Figure 3 are based on a 10°F change in fluid
temperature through the evaporators. Capacity and kW should be
obtained by extrapolating no more than 10°F from the lowest leaving
chilled-water temperature shown in the capacity tables. Multistack
should be contacted if leaving Glycol temperatures below 32°F are
required.
Adjustment factors for Propylene Glycol are shown in Figure 4, and are
used in the same way given in the following example.
ETHYLENE GLYCOL SELECTION
EXAMPLE (Assumes ASP-15 Modules)
Determine the capacity, gpm, pressure drop, and kW for an
ASP-15 module cooling 30% Ethylene Glycol from 45°F to
35°F, with design ambient-air temperature of 95°F.
1. By extrapolating from the performance tables: capacity: 11.5
tons; 15.8 kW
2. Evaporator water flow and pressure drop are determined for
water as in the previous example.
gpm = (24) (11.5) = 27.6 gpm
10
From Figure 2, read the pressure drop from the curve C pressure
drop = 2.6 ft of water
To convert performance for water to performance with Ethylene
Glycol, read adjustment factors from Figure 3 at 30% Glycol.
Capacity adjustment: 0.94
kW adjustment: 0.99
gpm adjustment: 1.10
Pressure drop adjustment: 1.22
Calculate performance with 30% Ethylene Glycol by multiplying
performance for water by adjustment factors.
Capacity: 11.5 x .94 = 10.8 tons
kW: 15.8 x .99 = 15.6 kW
gpm: 27.6 x 1.10 = 30.4 gpm
Pressure drop: 2.6 x 1.22 = 3.2 ft of water
If a water-temperature drop greater or less than 10°F is required, begin
by first multiplying the capacity using the performance adjustment
factor from Figure 1.

with the transfer of load requirements to the next available compressor. In the
case of a System Fault, the entire chiller will be shut down. When a fault occurs,
the Master Controller shall record conditions at the time of the fault and store
the data for recall. This information shall be capable of being recalled through
the keypad of the Master Controller and displayed on the Master Controller’s
LCD. A history of faults shall be maintained, including date and time-of-day of
each fault (up to the last 20 occurrences).
Individual monitoring of leaving chilled-water temperatures from each
refrigeration system shall be programmed to protect against freeze-up.
The control system shall monitor entering and leaving chilled water
temperatures to determine system load, and select the number of compressor
circuits required to operate. Response times and set points shall be adjustable.
LOW AMBIENT OPERATION
Each refrigerant circuit shall include all refrigerant specialties to provide reliable
operation down to 20°F ambient. With proper freeze protection.
OPTIONAL LOW AMBIENT TO -20°F
The chiller shall incorporate appropriate refrigerant specialties, including a
properly sized refrigerant receiver and flooded head pressure control valves for
operation to -20°F.
OPTIONAL SINGLE-POINT POWER CONNECTION

Free Cooling Modules shall interconnect through the common chiller header
system and require no additional water connections. Free Cooling Modules shall
include glycol cooling coils, temperature-controlled fans, and an automatic
3-way bypass valve to eliminate the need for mechanical cooling under lowambient conditions. The module shall be completely factory-assembled and
tested before shipment.
OPTIONAL PUMP MODULE
The Pump Module shall be interconnected through the common chiller header
system and require no additional water connections. The Pump Module
will become an integral part of the chiller system. The Pump Module shall
incorporate dual in-line centrifugal pumps in a Primary/Standby pumping
arrangement. Pump starters and controls shall be provided to enable manual
selection of lead pump. In addition, in the event of a loss-of-flow failure of
the chilled-water system, the Pump Module controls shall disable the lead
pump and automatically start the standby pump. The Pump Module shall be
completely factory assembled and tested prior to shipment.
OPTIONAL TANK MODULE
A factory-assembled Tank Module shall be provided, including an insulated
chilled water tank. The tank shall be pressure-rated at 150 psi minimum.
Tank Modules shall interconnect through the common chiller header system
and require no additional water connections. The Tank Module will become
an integral part of the chiller system. The Tank Module shall be provided with
proper drain and fill valving.
