Condenser Selection

Capacity for air-cooled condensers are based on Total Heat of Rejection (THR)
at the condenser. Total heat of rejection is equal to net refrigeration at the
evaporator (compressor capacity) plus the energy input into the refrigerant
by the compressor (heat of compression). The heat of compression will
vary depending on the compressor manufacturer, type of compressor
and the operating conditions of the compressor. Whenever possible, it is
recommended that you obtain the heat of compression value from the
compressor manufacturer.

If this is not available, the THR can be estimated using the following formula:

THR = (Compressor Capacity) * (Heat of Compression Factor, Tables 1 & 2)

Table 1 contains heat of compression factors for suction cooled compressors
and Table 2 contains factors for open drive compressors. For refrigeration
systems beyond the range of Tables 1 and 2, use the following equations to
estimate THR:

Open Compressors:

THR = Compressor Capacity (BTUH) + (2545) * (Break Horsepower, BHP)

Suction Cooled Compressors:

THR = Compressor Capacity (BTUH) + (3413 * KW)

The compressor capacity is eected by its altitude. If the condenser location
is above sea level, an additional correction is required to the THR, as follows:

THR (altitude) = THR * Altitude Correction Factor, Table 3

Selection Example

Compressor capacity: 350,000
Evaporator temperature: +25° F
Condensing temperature: 115° F
Ambient temperature 95° F
Refrigerant: R-22
Compressor type: Semi-hermetic, suction cooled
Condenser type: 540 RPM, one row of fans
Condenser altitude: 1,000 feet

THR (MBH) = 476,595 / 1,000 = 476.6

THR (MBH/°TD) = 476.6 / 20 = 23.83

Locate the 10 FPI column for R-22 refrigerant and read down until you locate a
value equal to or just larger than 23.83. This value is 25.9. Read horizontally to
the left to obtain a condenser model of BNQ-S05-A026.

Step 5: Calculate Actual T.D. and Condensing Temperature

The actual condenser T.D. can be calculated by dividing the design THR by
the condenser rating.
Actual T.D. = THR (Design) / (Rating @ 1° T.D.)
= 476.6 / 25.9
= 18.4°F. T.D.

The actual condensing temperature is the actual T.D. plus the ambient
temperature.
Actual Condensing Temperature = (Actual T.D.) + (Ambient)
= 18.4 + 95
= 113.4°F.

Condensing Temperature °F

Step 1: Estimate Condenser THR

From Table 1 for suction cooled compressors, at +25° F suction and 115° F
condensing temperature, select a heat of compressor factor of 1.335.

THR = Compressor Capacity * Heat of Compression Factor
= 350,000 * 1.335
= 467,250

Step 2: Correct for Altitude

From Table 3 obtain an altitude correction factor of 1.02 for 1,000 feet.

THR = THR (from step 1) * Altitude Correction Factor (design)
= 467,250 * 1.02
= 476,595

Step 3: Calculate Design Condenser T.D.

Design Condenser T.D. = Condensing Temp — Ambient Temp
= 115 - 95
= 20° T.D.

Step 4: Condenser Selection

Condenser capacities for condensers with one row of fans at 540 RPM are
located in Table 6. These capacities are given in MBH/°TD. Convert the THR
calculated in step 2 to MBH/°TD by dividing by 1,000 to get THR in MBH.
Then divide the THR by the design TD to get MBH/°TD.

Multi-Circuiting Selection

Multi-Circuiting Selection Procedure

The air-cooled condensers are available with more than one
refrigerant circuit. The condenser will be factory assembled with the
condenser coil divided into individual refrigerant circuits, each sized

Multi-Circuit Condenser Selection

Given four suction cooled compressors with conditions shown in Table

4. The condenser shall have 830 RPM, 1.0 HP fan motors,

Selection Procedure

Step 1: Input customer data in Table 4 in columns 1, 2, 3, 4

and 5.

Step 2: From Table 1, select the heat of compression factor

for suction cooled compressors and input into
Column #6.

Step 3: From Table 3 obtain the altitude correction factor

and input into Column #7.

Step 4: From Table 5 obtain the refrigerant capacity factor and
input into Column #8.

for its own specic application. Each circuit is supplied with its own
inlet and outlet connections, individually labeled.

with two rows of fans. The condenser location is at 3,000 ft. and the
design ambient is 95°F.

Step 5: Calculate the design T.D. for each circuit by
subtracting the ambient temperature from the circuit
design condensing temperature and input into
Column #9.

T.D. = Design Condensing Temperature - Ambient Temperature

Step 6: Calculate the design THR / °T.D. for each circuit.

Multiply Column #5 by Column #6 and Column #7 to
calculate the THR for each circuit. Divide the result by
the refrigerant correction factor, Column #8 to convert
the capacities to a common refrigerant. Divide the
result by the design T.D., Column #9 to calculate the
design THR / °T.D. and input into Column #10.

Design THR / °T.D. = Compressor Capacity (#5) * Heat of Compressor Factor (#6) x Altitude Factor (#7)
Refrigerant Capacity Factor (#8) * Design T.D. (#9)

Example for Circuit #1:

Design THR / °T.D. = 235,000 * 1.31 * 1.07

1.02 x 15

= 21,529 BTUH / °T.D.

Step 7: Add the design THR / °T.D. for each circuit in column
#10, to get a total of 39,578 BTUH / °T.D. Divide this
total by 1,000 to get 39.6 MBH / °T.D.

Step 8:

830 RPM, 1.0 HP fan motors, locate the column for
R-404A capacity with 10 FPI. Read down the column
until you get to a capacity equal to or greater than 39.6
MBH / °T.D. This value is 44.5 which corresponds to a
BNX-D06-A045. From Table 9 obtain the total
number of feeds available as 56.

Step 9: Determine the number of feeds per circuit. Divide the design THR / °T.D. in Column #10 by the total capacity required (39,578) and

multiply this result by the number of feeds available, which is 56. Round this value to the nearest integer and place in Column #11
Add the individual feeds per circuit to get a total number of feeds for the condenser. This total must equal the total number of
feeds available for the condenser (56).

ATD = Design T.D. (#9) * Design THR/°T.D. (#10) * Number of Feeds Available (56)
Number Feeds / CIR (#11) * Condenser Capacity / °T.D. (Step #8) * 1,000

Example for Circuit #1:

ATD = 15 * 21,529 x 56

= 13.1°F.

31 * 44.5 * 1,000

Input these T.D. values in column #12.

Step 11: Calculate the actual condensing temperature. Actual condensing temperature is equal to the actual condensing T.D., Column #12

plus the design ambient (95°). Input these values in Column #13. If the actual condensing temperature for each circuit is too high,
it may be necessary to adjust the number of feeds per circuit or to select the next larger condenser size and recalculate the number
of feeds per circuit.

Monarch Series

The new Bohn Monarch Series of air-cooled condensers
incorporates VSEC motor technology to provide the quietest
and most ecient condensers in the industry, using
integrated variable speed technology.

Simplicity: Variable speed without the complexity

The Bohn Monarch Series is a complete system that
incorporates an VSEC motor, integrated drive and control
electronics, optimized swept motor blade and venturi panel
in one simple package. Variable speed is accomplished
without the complexities typically associated with Variable
Frequency Drives.

Flexibility: Maximum eciency, minimum sound,
capacity when you need it

The Monarch Series condensers’ integrated variable speed
capability allows optimization to your operating conditions;
at higher speeds on hot summer afternoons to maintain
capacity or at lower speeds at night to meet a local sound
ordinance. Whatever your requirements, the Bohn Monarch
Series can be selected and programmed to your specic
needs; whether it is lower energy costs, lower sound or both.

Reliability: The highest quality backed
by industry-leading warranties

We are so condent in the reliability of the VSEC motor that
we are providing an unprecedented 3-year warranty on
the VSEC motor (2-year warranty on the unit) so you can be
assured of worry-free operation.

Protection at every level

The VSEC motors have several built-in features that protect
against locked-rotors, under-voltage and phase failure.

Variable Speed Operation

The Monarch Series condensers provide variable speed
operation automatically; providing dramatically lower sound
and energy levels than would be observed with condensers
using traditional AC motors.

Typical performance of a Monarch Series condenser at various
loads versus a 540 RPM or 1140 RPM condenser is shown in
the charts on the next page.

Model Selection

Selecting the right Bohn Monarch Series unit for your needs
is easier than you think, and is just as easy as selecting a
standard unit.

Simply use Table 12 to nd the model and ns per inch
required to meet your capacity needs.

Selecting condensers with specic sound or energy levels

The variable speed nature allows selection to meet maximum
sound or energy usage levels.

To select condensers with these goals in mind, please contact
your sales representative. They will be able to help you select
the appropriate model for your specic requirements.

Fan Cycle Control Panels

Fan cycling panels are available to cycle fans on ambient
temperature or condensing pressure or custom built control
panels can be factory installed to interface with electronic
refrigeration controllers.

• All fans are cycled with contactors.

• Condensers with a single row of fans cycle fans separately

with one contactor per fan.

• Condensers with two rows of fans cycle fans in pairs, with

one contactor for every pair of fans.

• Fans closest to the header end of the unit run continuously.

Ambient Fan Cycle

Condenser fans are controlled by ambient temperature
using electronic temperature controls. Ambient fan cycling is
recommended for multi-circuited condensers or single circuit
condensers where there is little variation in condenser load.

Ambient fan cycling is limited in its ability to control head pressure
to mild ambient conditions, see Table 16 for minimum ambients
for fan cycling. Full year head pressure control can be obtained
by combining ambient fan cycling with another means of head

Pressure Fan Cycling

• Standard control circuit voltage is 230 volts. Control
circuits with 24 or 115 volts are available on request.

• Control circuits are factory wired to a control circuit
terminal board for convenient single point eld wiring.

• Standard control circuits require an external power supply
for powering control circuit (by others).

• A control circuit transformer is available on 460 volt
condensers as a factory mounted option to provide
power to the control circuit.

pressure control, such as condenser ooding controls or variable
speed. Combining these controls with ambient fan cycling has the
additional advantage of reducing the amount of refrigerant required
to ood the condenser.

See Table 17 for typical settings for ambient thermostats.

Condenser fans are controlled by pressure switches which
monitor condenser pressure. Pressure fan cycling is ideal for
those condensers which see a signicant change in condenser
load. Since the controls sense condensing pressure, they can
cycle fans at any ambient temperature, in response to a change in
condensing pressure.

An additional pressure switch is available as an option to cycle the
fan closest to the header end of the condenser. This option is only
recommended for condensers with large variations in condenser
load caused by heat reclaim, hot gas defrost or a high percentage of
compressor unloading.

Variable Speed

Condenser head pressure control is provided by varying the air ow through the condenser by changing the RPM of the condenser fan. This
control package is oered in combination with ambient fan cycling. The fan motor next to the header end of the condenser is the variable
speed fan. The remainder of the fans are constant speed and are cycled separately using ambient sensing thermostats. On condensers with
two rows of fans, two variable speed fans are provided (one per row) and the remainder of the fans are constant speed and are cycled in
pairs. The variable speed control package consists of a special variable speed motor (1140 RPM, single phase) and an electronic speed control
which controls the speed of the motor in response to condensing pressure. Fan motor, speed control and all related components are all
factory mounted and wired. Two speed controls are provided on units with two rows of fans to allow for separate control of each fan motor.

Splitting Controls

Additional head pressure can be provided by valving o a portion of the condenser circuit and removing that portion from the refrigeration
circuit, or splitting the condenser. In addition to providing a means of head pressure control, this control will reduce the amount of refrigerant
required to operate the condenser with a ooded head pressure control. Condenser splitting is recommended as a seasonal adjustment
controlled by ambient temperature. A pressure switch is also provided as a backup control to prevent high head pressures from occurring
during heavy load conditions. On condensers with a single row of fans the control package consists of an ambient sensing thermostat, a
pressure switch sensing condensing pressure and a splitting relay. The splitting relay provides a set of dry contacts to control the valves
required to split the condenser (valves supplied by others). On condensers with double rows of fans, additional controls and contactors are
provided to cycle all of the fans on the side of the condenser which has been split o. Except as noted above, the splitting packages do not
control fan cycling. It is recommended that fan cycling be controlled by combining the splitting package with pressure fan cycling.

Control Panels for Electronic Controllers

Custom control panels can often be fabricated to interface with many of the microprocessor based electronic refrigeration controls.
These panels often include individual motor fusing, individual fan motor contactors, splitting relays and printed circuit boards to
interface with the microprocessor control. Contact the factory with your specic requirements.

Condenser Refrigerant Charge

The normal summer operating charge for condensers is shown
in Table 18. This charge can also be used in condensers with fan
cycling kits, since added refrigerant is not required for mild weather
control. Table 18 also contains the additional refrigerant charge
required when using ooded style head pressure controls.

Combining fan cycling with ooded head pressure controls
signicantly reduces the amount of winter charge required to ood
the condenser. Table 20 shows the refrigerant charge required
when fan cycling is used in conjunction with a ooded style head
pressure control.

Calculate Refrigerant Charge

Refrigeration operating charges are located in Table 18 for ooded condenser and Table 20 for fan cycling plus ooded condenser.

Charge for ooded condenser = summer charge (Table 18) + additional ooding charge (Table 18) * ooded charge T.D. factor (Table 19)

Charge for fan cycling + ooding = summer charge (Table 20) + additional charge for fan cycling (Table 20)

Example:
Obtain the summer charge for a BNH-S05-A037. What is the ooding charge required to operate this condenser at 0° ambient at a
R-22 refrigerant? What is the reduction in operating charge if fan cycling is combined with ooding?

Procedure:
From Table 21, obtain the model reference for BNH-S05-A037 as model 10. From Table 18, obtain the summer operating charge for model 10
at 64 lbs. The charge for winter operation with ooded controls is equal to the summer operating charge of 64 lbs. plus the additional charge
at 0° ambient (Table 18) of 95 lbs., times the ooded charge T.D. factor (Table 19) of 1.0 for 20°T.D.

Charge for ooded condenser = 64 + (95) * 1.0
= 159 lbs.

The charge for fan cycling plus ooded condenser is obtained using Table 20. Using this table obtain the additional charge for 20°T.D. at 0°
ambient, which is 17 lbs. The total charge is the summer charge (64 lbs.) plus the additional charge.

Charge for fan cycle + ooding = 64 + 17
= 81 lbs.

The savings in refrigerant charge = 159 - 81
= 78 lbs.
