YORK Air-Cooled Condensers, Models VDC-113D10 through VDC-266C60, are available in 66 standard model sizes for air conditioning and refrigeration applications and may be used with any type of compressor for halocarbon refrigerants.

Similar units are available for industrial fluid cooling. Contact Johnson Controls for special applications, and refer to Form 195.29-EG2 for additional information.

Air-cooled condensers operate dry (requiring a minimum of maintenance) and do not require pump and water piping installation. Vertical airflow units are standard design for low silhouette applications.

LEGS – Made from heavy-gauge galvanized steel with foot pads and mounting holes on the bottom of each leg.

COIL – Seamless copper tubes are expanded into full-collar aluminum fins. Fins have a corrugated surface to enhance heat transfer. Fin edges are rippled to work harden and stiffen material for resistance to mechanical damage. Return bends and headers are brazed with highly ductile silver-bearing copper alloy. Coil casings and tubesheets are manufactured from galvanized steel. The tubesheets include aluminum inserts to prevent wear at the juncture of the tubes and tubesheets.

Prior to shipment, coils are strength and leak tested at design pressure, dehydrated, evac-uated, pressurized with dry air or nitrogen, and sealed for shipment.

Coils up to four fan lengths use 3/8 in. OD internally-enhanced microfin tubes for optimum performance. Five- and six-fan length coils use 1/2 in. OD tubes.

For R-22, R-134a, R-407c, R-404A, and R-507A condensing, the 3/8 in. OD and 1/2 in. OD tube coils have a 420 psig (29 barg) design pressure at 250°F (121°C) for up to a 140°F (60°C) condensing temperature. For R-410A, the 3/8 in. OD tube coils have a 650 psig (44.8 barg) design pressure at 250°F (121°C) for up to a 140°F (60°C) condensing temperature.

HEADERS – Heavy-wall copper tube headers are designed for low pressure loss and proper refrigerant distribution. Double-wide units feature completely separate headers for each system circuit so there is no danger of refrigerant leakage between circuits. Inlet and outlet connections are provided. Integral subcooling is available.

HOUSING – The unit structure is comprised of heavy-gauge galvanized steel panels in-dividually pre-coated with baked-on champagne-colored powder paint, which, when sub-jected to ASTM B117 1000 hour salt spray testing, yields a minimum ASTM 1654 rating of “6”. These panels are assembled with high-tensile strength fasteners. Fan panels have smooth-radius outlet orifices to ensure high energy efficiency and low noise level. Each fan-section is fully compartmentalized to prevent fan windmilling

FAN GUARDS – Heavy-gauge OSHA-accepted fan guard design uses corrosion-resis-tant, coated-steel wire.

FANS – High-efficiency, high-strength airfoil-profile blade fans are used for low noise and energy-efficient performance.

Accessories and Options

SPECIAL COILS

While standard aluminum fins are compatible with most environments, when a unit is subjected to an especially corrosive atmosphere, such as coastal air with a high concen-tration of salt, special fin treatment may be required. The following options are available for these applications.

Holly Gold Coat – This gold-colored, corrosion-resistant, polyester-polymer-coated alu-minum fin passes 1000 hours of ASTM B117 salt spray testing. Available only with 3/8 in. OD tube coils.

Electrofin™ Coat – ElectroFin Coat is applied to the completed coil, protecting the tubes, fins, headers, and galvanized steel casing with a coating that passes 5000 hours of ASTM B117 salt spray testing. Not included in shipped loose manifold kit.

Copper Fins – Copper-finned coils are available for applications where the environment may cause galvanic corrosion of aluminum fins. Available only with 3/8 in. OD tube coils.

SEALTITE™ CONDUIT – All fan motor wiring enclosed in sealed conduit.

EXTENDED LEGS – Taller than standard legs, these 30 in. and 36 in. legs, available by SQ, provide additional space below the unit without changing mounting dimensions.

MANIFOLD KIT – Ties dual inlet and outlet connections together on double-wide units for a single field connection (shipped loose for field installation). Typically used with a single chiller circuit or fluid coolers.

ENERGY EFFICIENT MOTORS – Alternate 1.0 hp (0.75kW) motor choice means capac-ity can be closely matched to application requirement to give maximum BTU/h per hp (kW) with lower sound levels.

MOTOR CONTROL OPTIONS

Fan Cycling – Fan Cycling Options have motors wired to contactors located in a UL-listed NEMA 4, weather-resistant enclosure, which includes a non-fused disconnect switch, mo-tor fuses, contactors, and an integral 115 volt control transformer. See Table 11 - CON-NECT DRIVE TERMINALS TO APPROPRIATE CONTROL PANEL TERMINAL BLOCK LUG on page 41 and Table 12 - MINIMUM AMBIENT TEMPERATURES FOR FAN CYCLING CONTROL on page 43, respectively, for fan-cycling control settings or con-tact Application Engineering for support. Enclosure ships mounted. If there is a concern about noise due to fan cycling, It is recommended that HEAD PRESSURE CONTROL (VSD READY) be used.

Double-Wide-Unit Fan Cycling – Fan Cycling Options for Double-Wide Units are avail-able with fans cycling in pairs or, for temperature-controlled and pressure-controlled fan cycling, with individual fan-bank fan cycling so the VDC circuit can serve individual chiller circuits.

JOHNSON CONTROLS8

FORM 195.29-EG1 (615)

FAN CYCLING OPTIONS

Head Pressure Control By Temperature – Motors are wired for temperature-controlled fan cycling. A temperature sensor, supplied with a clip for mounting in the condenser’s air stream or a bulb well for installation in fluid cooler’s leaving fluid piping, must be field installed. Fans next to the header are always running when unit is activated by run signal. Receivers are not required.

The A350 controller and stage module are supplied with this option to control the fans.

Head Pressure Control By Pressure – Required when selecting a VDC for use as a re-mote condenser for a YCRL chiller. Motors are wired for pressure-controlled fan cycling. Included pressure transducer(s) must be field installed. Fans next to the header are al-ways running when unit is activated by run signal. Receivers are not required.

The P470 controller and stage module are supplied with this option to control the fans.

Head Pressure Control (VSD Ready) – Motors are wired for variable speed fan control. VSD bypass control circuit is included, but inverter drive (VSD) is not included. Tempera-ture or pressure sensor(s) for control must be field provided and installed, if desired.

Field-installed inverter drives (VSDs) shall be mounted on or in close proximity to the VDC unit. The inverter drive shall be equipped with load reactors for installations that require more than 25 feet of wire between the inverter and the VDC unit or whenever distortion is a concern too prevent voltage spikes that can damage the fan motors and void the VDC motor warranty. Motor damage caused by an improperly installed VSD is not warranted.

The VSD's switching frequency shall not exceed 4KHz.

When this option is selected, the option Sealtite™ Conduit shall also be selected to en-sure that the motor wire is shielded from voltage spikes. Grounding of conduit and all wiring is of extreme importance. See Figure 12 - Factory Wiring For Electronic Variable Speed Drive (VSD) Fan Controlled Two To Six Fans Long on page 40.

Selection Data

YORK remote air-cooled condensers are rated by Total Heat of Rejection (THR) at the condenser (expressed in Btu/h), at sea level air density. Total Heat of Rejection is the sum of the net refrigeration at the evaporator (compressor capacity) plus the energy input into the refrigerant by the compressor (heat of compression). Due to variations in the heat of compression by compressor type and manufacturer, it is recommended that the heat of compression value is obtained from the compressor manufacturer.

However, if this is not available the Total Heat of Rejection can be estimated by applying correction factors and information in the tables below to the evaporator load to determine the THR requirement. Please refer to the examples on the following page for the estima-tion procedure.

The two formulas that will be used are:

Two-stage open compressor applications: THR = compressor capacity (BTUH) + (2545 x bhp)

Two-stage suction-cooled hermetic compressor applications: THR = compressor capacity (BTUH) + (3413 x kW)

FORM 195.29-EG1 (615)

SOLUTION:

Step 1: Estimate Condenser THR (if THR is provided, skip to step 2)

THR = Compressor Capacity * Heat of Compression Factor

1. From Table 2, opposite 40°F evaporator temperature and under 120°F condensing, select heat of compression factor 1.27.

2. Multiply compressor or evaporator capacity by factor: THR = 250,000 Btuh x 1.27 = 317,500 Btuh.

Step 2: Correct THR for Elevation and Ambient Temperature

THR (corrected to sea level) = THR ÷ Air Density Correction Factor

1. From Table 3, under 3000 ft. elevation and opposite (interpolated) 95°F air temp, select air density correction factor 0.856.

2. Divide THR (from step 1) by factor: THR (corrected) = 317,500 Btuh ÷ 0.856 = 370,911 Btuh (at sea level).

Step 3: Correct for Subcooling

THR (subcooling adjusted) = THR ÷ Subcooling Correction Factor

1. From table 4, select 0.94 factor under “10°F Subcooling” column.

2. Divide THR (from step 2) by factor: THR (subcooling adjusted) = 370,911 Btuh ÷ 0.94 = 394,586 Btuh (adjusted for sea level and subcooling).

Step 4: Select Condenser

Condenser ratings are provided as Btuh-°F TD, so required THR must be divided by TD to obtain basic unit rating at 1°F TD.

1. Divide required unit capacity by TD (25°F) to obtain basic unit rating at 1°F TD: 394,586 Btuh ÷ 25°F = 15,783 Btuh-°F TD.

2. From Unit Ratings table, page 18, under R-410A heat rejection, select model VDC-126D60 with a base capacity of 16,793 Btuh-°F TD for lower first cost.

3. From Unit Ratings table, page 24, under R-410A heat rejection. select model VDC-133D10 with a base capacity of 16,216 Btuh-°F TD for higher energy efficiency.

Step 5: Calculate actual operating TD for unit selected

Actual operating TD = THR (corrected) divided by basic unit capacity.

1. To determine TD at which VDC-126D60 will operate, divide THR (corrected) by base unit capacity: 394,586 Btuh ÷ 16,793 Btuh-°F TD: TD = 23.5°F TD.

2. Model VDC133D10 will operate at 394,586 Btuh ÷ 16,216 Btuh-°F TD: 24.3°F TD.

AIR-COOLED CONDENSERS FOR CHILLER APPLICATIONS

YORK air-cooled condensers are available with matched liquid chillers for air conditioning or process applications.

The following table lists scroll chillers cooling chilled water from 54°F to 44°F, using R-410A and condensing at 125°F saturated discharge temperature (SDT). They have been matched with an air-cooled condenser providing 10°F subcooled R-410A refrigerant to the chiller and operating under a 25°F TD (temperature difference between ambient and condensing temperatures). These ratings therefore represent a design ambient tempera-ture of 100°F.

Application Data

PIPING DIAGRAMS

The below piping diagram covers a common application where the air-cooled condenser is located on the same elevation as the compressor and receiver. The discharge line in this case is not too critical. The main problem usually associated with this arrangement is insufficient vertical height to allow free draining of the liquid refrigerant from the con-denser coil to the receiver.

To prevent gas binding in the receiver and liquid build-up in the condenser coil, locate the receiver as far below the condenser outlet as possible. Liquid lines must be free of any loops or traps and horizontal runs must be pitched toward the receiver.

FIGURE 2 - AIR-COOLED CONDENSER ON SAME ELEVATION AS COMPRESSOR AND RECEIVER*

This piping diagram is recommended for applications of capacity controlled systems. Dis-charge line A is sized for the maximum load conditions. Discharge line B is sized for the minimum loading conditions at sufficient velocity to carry the oil to the condenser at the reduced capacity.

This diagram illustrates a typical piping arrangement where the remote air-cooled con-denser is located on a higher elevation than the compressor or receiver. In this arrange-ment, the design of the discharge line is very critical and should be modified to the ar-rangement in diagram Figure 2 on page 30, unless a very constant and steady load is maintained.

FIGURE 4 - REMOTE AIR-COOLED CONDENSER AT HIGHER ELEVATION*

This diagram illustrates another common application where two or more separate air-cooled condensers are interconnected to a single compressor. In this case, each con-denser must have both equal capacity and equal pressure drop. The piping must also be so arranged as to insure equal lengths to and from each condenser. If unlike piping and/or unequal condensers are used, the unequal pressure drop will cause liquid to build up in one of the condensers, reducing its effective capacity.

* Note: Receivers are shown in Figures 2 through 5 starting on page 30 for conve-nience. Many applications do not require receivers when the volume of the refrigerant charge does not exceed 80% of the condenser coil internal volume and can be entirely stored in the condenser coil.

VDC PRESSURE SETTING GUIDELINES

When a YORK VDC remote condenser is used with a YCRL chiller, the VDC must be ordered and installed with the “Head Pressure Control – High Pressure” option which pro-vides YORK model P470 pressure controllers factory mounted in the VDC control panel. Operating manuals for the P470 controllers are included in the VDC control panel to allow field setup of the fan staging.

Johnson Controls recommends the following pressure set points for general use; if ex-cessive fan cycling is noted the final stage of cycling should be adjusted (deadband in-creased). The dead band proposed in these guidelines is set to 125 psi, which is the standard setting for Johnson Controls air cooled R-410 units (YLAA, YCAL).

2 stage units (2 fan single wide, 4 fan double wide VDC):

Stage 1, ON when any compressor is ON

Stage 2, ON at 380 psig, OFF at 255 psig



Stage 2, ON at 380 psig, OFF at 255psig

Compressor will unload when the discharge pressure reaches 565 psig.

LOW AMBIENT OPERATION

Since air-cooled condensers are often required to operate over a wide range of ambient air temperatures and variable loading conditions, provision must be made to maintain the overall system balance. Any air-cooled condenser tends to run at a low head pressure when operating in a low ambient air temperature. Low head pressures will result in poor expansion valve operation and this will in turn cause poor system operation due to the pressure imbalance.

Air conditioning applications generally allow the operating head pressure to vary with the ambient air temperature within certain limits, without adversely affecting the system op-eration. The capacity of an air-cooled condenser is directly proportional to the TD, which is the temperature difference between the air temperature entering the condenser and the condensing temperature. A condenser is usually selected to operate on a TD suitable for summer ambient air conditions. The capacity of the condenser is increased when oper-ated at the lower ambient temperature which directly reduces the system head pressure.

The lower limit of this varying head pressure is dependent upon the required pressure drop across the thermostatic expansion valve and, for normal air conditioning applica-tions, should be maintained above that corresponding to a condensing temperature of 65° to 70°F. This, in effect, corresponds to an ambient air temperature lower limit of ap-proximately 55° to 60°F.

Air conditioning is usually not required at these ambient temperatures. However, to en-sure sufficient receiver pressure during compressor start-up, it is recommended that a high-pressure cut-in switch be used to allow the head pressure to rise before the con-denser fan starts.

LOW AMBIENT CONTROL OPTIONS FAN CYCLING CONTROL

On multiple-fan units, individual fan sections can be cycled to not exceed nominal con-denser capacity at low ambient conditions. “Table 12 - MINIMUM AMBIENT TEMPERA-TURES FOR FAN CYCLING CONTROL on page 43” provides minimum ambient tem-peratures for effective fan cycle control. Lower ambient temperatures than listed are not recommended for this method of control. Table 13 - TEMPERATURE SETTINGS FOR FAN CYCLING on page 43 gives temperature settings for all units referenced to various design temperature differences. In lieu of temperature control, fan cycling can be con-trolled by pressure controls using a factory provided pressure transducer inserted (by others) into condenser inlet piping. Specify the type of control when ordering this option.
