Remote Air Cooled Condensers

Condenser Selection
Air-cooled condenser capacity ratings are based on the total heat rejection of the refrigeration system. Total heat of rejection is the sum of the compressor capacity and heat of compression added to the refrigerant in the compressor.
The heat of compression varies with the compressor design, so the compressor manufacturer’s information should be used whenever possible. If the compressor manufacturer’s heat of compression information is not available, Tables 2 and 3 (page 7) may be used to determine the heat of compression.
The following formulas may be used to calculate the total heat rejection (THR) for systems that fall outside the normal limits of single stage compressor applications, such as compound or cascade systems.

• Suction cooled hermetic compressors: THR = Compressor Capacity (BTUH) + (3413 x KW)
• Open Compressors: THR = Compressor Capacity (BTUH) + (2545 x BHP)

ELEVATION CORRECTION
Elevation above sea level has an effect on the performance of air cooled condensers. Divide the required capacity by the Elevation Correction Factor in the table on page 7 to correct the requirement to Sea Level Conditions. The proper condenser can then be selected from the appropriate table on Pages 8, 10, 12, 14, 16 or 18.

SINGLE CIRCUIT CONDENSERS
All units are available for single circuit applications. All double fan width units are furnished with dual circuit coils and can be converted in the field for single circuit installations.

SELECTION EXAMPLE
Given:

• Ambient Air Temperature = 100° F
• Midpoint Condensing Temperature* = 115° F
• Evaporating Temperature = +20° F
• Compressor Type = Suction Cooled Semi-Hermetic *Refer to Midpoint Selection Graph for explanation
• Design DT = 15° F
• Refrigerant = R407A Compressor Capacity = 140,000

Solution:
Multiply the compressor capacity by the heat of compression factor to calculate the required total heat of rejection (THR). Table 1 shows that for 115°F condensing temperature and 20° F evaporator temperature, the heat of compression factor is 1.35. The required total heat rejection (THR) is: 140,000 x 1.35 = 189,000 BTUH THR

• Divide the system THR by the condenser delta T (Midpoint Temperature-Ambient Air) = 189,000 ÷ 15 = 12,600 BTUH per 1°F TD
  Convert BTUH to MBH = 12,600 BTUH ÷ 1,000 = 12.6 MBH per 1°F TD

• The correct selection of a single fan width unit with 850 RPM 1 HP fans and 10 FPI is a model KDS015^L2 with a capacity of 15.1 MBH.

Since the unit selection will almost never have the exact required capacity, the actual TD will vary slightly from the design TD. The actual TD can be calculated using the following formula: For this example the actual TD would be:

• • To avoid oversizing, the condenser is selected at the Midpoint Temperature. The Midpoint is the average of the Dew Point and Bubble Point temperatures corresponding to the conditions at the condenser inlet.
• The Refrigerant Quality in the chart refers to the percentage of vapor in a saturated mixture. The glide occurs across the change from liquid to vapor.
• BTUH capacities published in this document for refrigerants other then R404A are based upon this Midpoint Selection Chart.

Multi-Circuited Condensers
Air-cooled condensers are available for applications where multiple refrigeration systems are connected to the same condenser. Multi-Circuiting is covered in this section.
The condenser coil is divided into the proper number of circuits and each circuit is supplied with an inlet and outlet connection. Each circuit is tagged at the factory for identification. When ordering, the circuits must be placed on the purchase order in numerical sequence. The circuits will be arranged in sequence with the number one section being on the left end when facing the header end of the unit.

EXAMPLE: MULTI-CIRCUITED CONDENSER SELECTION
Given:
Refer to Table 1, the Multi-Circuit Calculation Form below. Four suction cooled semi-hermetic compressors are shown with their operating conditions. Design ambient temperature is 95° F.

Procedure:

1. Complete the customer data in columns 1 through 6 in Table 1.
2. Fill in the heat of compression factors in column 7. If the compressor manufacturer’s data is not available, use values from tables 2 and 3.
3. Multiply the values in column 6 by the values in column 7 and tabulate the results in column 8.
4. Next, divide the heat rejection values in column 8 by the design TD values in column 3 and enter the results in column 9.
5. Add all of the items in column 9 to obtain the total MBH required at 1° F TD. Use this value and the procedure on Page 5 to select the proper condenser model. For this example, the total MBH is 25.6. Therefore, the unit with 1140 RPM fan motors and double fan-width configuration, having enough capacity to meet this requirement, is an KDD030*B2 with 10 FPI.
6. MBH per face tube values can be found by dividing the unit’s capacity, found in the performance data tables, by the number of face tubes listed in Table 5 (page 21). Be sure to apply the corresponding correction factors for refrigerants other than R404A or R407A. Enter the MBH per face tube value in column 10.
7. To determine the number of face tubes required for each circuit, divide column 9 by column 10 and enter the results in column 11.
8. Each circuit’s number of face tubes in column 11 is a mathematical value and must be rounded off to a whole number and entered into column 12. Round each number off such that the section size assigned to each system is no smaller than 10%undersized.
9. Total the values in column 12. The sum must equal the number of face tubes available for the KDD030*B2 as shown in Table 5 (page 21). If it does not, one or more of the column 12 numbers will have to be adjusted so the sum does equal the available face tubes.
10. The actual TD in each coil circuit may vary slightly from the design TD. The actual TD can be calculated using the following formula: The actual TD for Circuit No. 3 would be:

Head Pressure Control Options and Refrigerant Charge Calculations

FLOODED CONDENSER
The Flooded Condenser Head Pressure Control Option maintains adequate condensing pressure while operating in low ambient temperatures. By flooding the condenser with liquid refrigerant, the amount of coil surface available for condensing is reduced. The resulting reduction in capacity ensures proper operation of the thermal expansion valve(s). This option requires that a modulating valve for each circuit, dependent on refrigerant discharge pressure, be placed at the condenser outlet. A fall in ambient temperature causes a corresponding fall in discharge pressure. The valve modulates to force liquid to back up into the condenser. Flooding the condenser reduces the available condensing surface and raises the condensing pressure so that adequate high-side pressure is maintained. A larger receiver and additional refrigerant (supplied by others) are required for systems with flooded condenser control. The receiver can be conveniently installed directly under the condenser in most applications. However, if the system will be operational in ambient temperatures below 55° F, the receiver should be located in a warm environment or heated and insulated. In this situation, a check valve must be installed in the line between the receiver and condenser. This prevents refrigerant migration from the receiver to the condenser. The amount of additional refrigerant charge is based on the lowest expected winter operating temperature and the design TD. In addition to the condenser charge, the operating charges of the evaporator, receiver and refrigerant lines must be added to determine the total system refrigerant charge. The pump-down capacity (80% of full capacity) of the receiver must be at least equal to the total system charge. Table 5 shows the standard summer charge when using R407A. The additional charge required for flooded condenser operation with a design TD of 15°F is also shown. Additional charge for alternate design TDs can be found using the correction factors in Table 6. For flooded condenser control only, Total Charge = Summer charge (Table 5) + additional charge (Table 5) × design TD correction factor (Table 6)

EXAMPLE: SINGLE CIRCUIT UNIT WITH FLOODED CONDENSER HEAD PRESSURE CONTROL
Given:
A KDD030*B2 Condenser with a R407A summer charge of 26.6 lbs. (See Table 5) has a design TD of 10° F and will operate at a minimum ambient of 0° F.
Solution:
The additional charge needed to operate at 0° F can be found in Table 5 (69.0 lbs.). Because the unit has a design TD of 10° F, the additional charge must be multiplied by a correction factor of 1.04 as shown in Table 6. Therefore, the required additional charge is 69.0 × 1.04 = 71.8 lbs. The total operating charge for a minimum ambient of 0° F and a 10° design TD is 26.6 + 71.8 = 98.4 lbs.

EXAMPLE: MULTI-CIRCUIT UNIT WITH FLOODED CONDENSER HEAD PRESSURE CONTROL
Given:
A KDS012 condenser split into two circuits. One circuit has 22 face tubes of R404A at a 10° TD and the other circuit has 14 face tubes of R407A at a 15° TD. The unit will operate at a minimum ambient of 20° F.
Solution:
To calculate the winter charge for each circuit , the summer charge and additional charge for low ambient must be found. The summer charge can be calculated by multiplying the number of face tubes in the circuit by the charge per face tube value in Table 5. Next, divide the number of face tubes in the circuit by the total number of face tubes and multiply by the additional charge required for a minimum ambient of 20° F. Make sure to apply correction factors for design TDs other than 15° and for refrigerants other than R407A. Adding the summer charge and additional charge for low ambient will yield the total winter charge. For the R404A circuit , the summer charge is 22 tubes × 0.25 x 0.92 lbs. (404A correction factor) per face tube = 5.06 lbs. The additional charge equals the ratio of tubes in the circuit to total tubes times the additional charge at 20° F with a 15° F TD times the TD correction factor from Table 6, or 22/36 × 20.8 × 1.05 x .92 = 12.26 lbs. The winter charge is 5.06 + 12.26 = 17.32 lbs. For the R407A circuit, the summer charge is 14 × 0.25 = 3.5 lbs. The additional charge calculation also requires the use of the correction factor. The additional charge is 14/36 × 20.8 = 8.08 lbs. The winter charge is 3.5 + 8.08 = 11.58 lbs.

FAN CYCLING CONTROL OPTION
The cycling of condenser fans provides an automatic means of maintaining condensing pressure control at low ambient air temperature conditions. It also results in substantial fan motor power savings in lower ambient. Temperature sensing thermostats or pressure controls determine whether the motor is on or off. The minimum ambient temperatures for units with the Fan Cycling Control Option can be found in Table 7 (page 22). The Fan Cycling Control Option consists of a weatherproof enclosure, fan contactors, and either ambient thermostat(s) or pressure control(s). The enclosure is factory mounted and completely factory wired. Power must be supplied from a fused disconnect switch to the power circuit terminal block; control circuit power must be supplied to the control terminal block. Table 8 (page 22) shows the recommended temperature set points for the thermostats. Thermostat 1 is for the second fan from the header end, Thermostat 2 for the third fan from the header end, etc. The fan(s) nearest the header end must run continuously, and can’t be cycled.

FAN SPEED CONTROL OPTION (Fan Cycling Control Option also required for this option)
Designed to enhance the performance of the Fan Cycling Control Option by reducing the RPM and air volume of the lead (header end) fan motor(s) after all other (lag) fans have cycled off. The lead fan(s) must run continuously, even in the lowest ambient temperature. By reducing their CFM, adequate head pressure can be maintained at lower ambient temperatures without resorting to flooded condenser head pressure controls. This option includes an inverter and pressure transducer. All components are factory mounted and wired. Controller decreases fan motor RPM as head pressure decreases. See Table 7 (page 22) for minimum ambient temperatures for units with both the Fan Cycling Control Option and Fan Speed Control Option.
