Application ConsiderationsApplication of this product should be within the cataloged airflow and cooling considerations.

Barometric ReliefThis product line offers an optional barometric relief damper for use in conjunction witheconomizer option.This accessory consists of gravity dampers which open with increasedpressure. As the building air pressure increases, the pressure in the unit return air section alsoincreases, opening the dampers and relieving the conditioned space.

Note: The effectiveness of barometric relief damper during economizing operation is systemrelated. Pressure drop of the return air system should be considered to control buildingpressurization.

Black Epoxy CoilThe coils are manufactured with a thermoset, vinyl coating that is bonded to the aluminum fin stockprior to the fin stamping process.These coils are an economical option for protection in mildlycorrosive environments.

Note: Not to be used where seacoast applications exist.

Note: Not available on Microchannel condenser coils.

Clearance RequirementsThe recommended clearances identified with unit dimensions should be maintained to assureadequate service maximum capacity and peak operating efficiency. Actual clearances whichappear inadequate should be reviewed with the localTrane sales personnel.

CompleteCoat™ Condenser CoilThe coils provide protection from corrosive environments and are ideal for seacoast applications.

18 RT-PRC023-EN

Selection Procedure

Cooling CapacityNote: Cooling Capacity Procedure is the same for electric heat (T*C) and gas heat (Y*C).

Step 1.

Calculate the building’s total and sensible cooling loads at design conditions. Use the Tranecalculation methods or any other standard accepted method.

Factors used in unit selection:• Packaged Cooling with Optional Electric Heat• Total Cooling Load: 59 MBh• Sensible Cooling Load: 40 MBh• Airflow: 2000 cfm• Electrical Characteristics: 460/60/3• Summer Design Conditions: Entering Evaporator Coil: 80 DB• 67 WB Outdoor Ambient: 95• External Static Pressure: 0.36 in. wg• Downflow Configuration• Efficiency: 13 SEER• Economizer

Step 2.As a starting point, a rough determination must be made of the size of the unit.The final selectionwill be made after examining the performance at the given conditions. Divide the total cooling loadby nominal Btuh per ton (12 MBh per ton); then round up to the nearest unit size.

59 MBh / 12 MBh = approx. 5 tons

Step 3.

Table 13, p. 45 shows that aTSC060E4 has a gross cooling capacity of 62.3 MBh and 48.1 MBhsensible capacity at 2000 cfm and 95 DB outdoor ambient with 80 DB, 67 WB air entering theevaporator.

To Find Capacity at Intermediate Conditions not in the table.

When the design conditions are between two numbers that are in the capacity table, interpolationis required to approximate the capacity.

Note: Extrapolation outside of the table conditions is not recommended.

Step 4.

In order to select the correct unit which meets the building’s requirements, the fan motor heat mustbe deducted from the gross cooling capacity.The amount of heat that the fan motor generates isdependent on the effort by the motor - cfm and static pressure.To determine the total unit staticpressure:

Note: The Evaporator Fan Performance Table 36, p. 81 has deducted the pressure drop for a filteralready in the unit (see note below Table 36, p. 81).Therefore, the actual total static pressureis 0.535 -0.049 (from Table 145, p. 186) = 0.486 wg.

External Static Duct System 0.36 wgStandard Filter 2 in. from Table 145, p. 186 0.049 wgEconomizer from Table 145, p. 186 (100% Outside Air) *worst case

0.105 wg

Electric Heater Size 6 kW from Table 145, p. 186 0.021 wg(reference "Heating Capacity" section on this page for determination of heater size)Total Static Pressure 0.535 wg

RT-PRC023-EN 19

Selection Procedure

With 2000 cfm and 0.5 wg.Table 36, p. 81 shows 0.575 bhp for this unit.

Note: Below the table is the formula to calculate Fan Motor Heat

2.87 x bhp + 0.75 = MBh.2.87 x 0.575 + 0.15 = 1.8 MBh.

Now subtract the fan motor heat from the gross cooling capacity of the unit:

NetTotal Cooling Capacity= 62.3 MBh - 1.8 = 60.5 MBh.

Net Sensible Cooling Capacity= 48.1 MBh - 1.8 = 46.3 MBh.

Subtracting Sensible fromTotal Capacity to find Latent Capacity

Net Latent Capacity= 60.5 - 46.3 = 14.2 MBh.

Step 5.

Compare your resulting capacities to the building load. If the performance will not meet therequired load of the building’s total or sensible cooling load, try a selection at the next higher sizeunit.

Heating CapacityNote: Heating capacity procedure DIFFERS for electric heat (T*C) and gas heat (Y*C) units

Step 1.

Calculate the building heating load using the Trane calculation form or other standard acceptedmethod.

Step 2.

Size the system heating capacity to match the calculated building heating load.The following arebuilding heating requirements:Total heating load of 15 MBh2000 cfm

T*C units with optional electric heat: 460V/3 phase Power Supply

The electric heat accessory capacities are listed in Table 148, p. 189. From the table, a 6 kW heaterwill deliver 20.48 MBh at 480 volts. In order to determine capacity at 460 volts, the heater voltagecorrection factor from Table 150, p. 191 must be used.Therefore, 20.48 MBh x 0.918 (voltagecorrection factor) = 18.8 MBh.

Y*C units with gas heat: Fuel- natural gas.

60 MBh, 80 MBh and 130 MBh input models shown in Table 146, p. 187.The output capacities ofthese furnaces are 48 MBh, 64 MBh and 104 MBh respectively.The low heat model with 48 MBhbest matches the building requirements.

Air Delivery SelectionNote: Air Delivery procedure is the same for electric heat and gas heat units.)

External static pressure drop through the air distribution system has been calculated to be 0.5inches of water. Enter Table 52, p. 97 for aTSC060E4 at 2000 cfm and 0.5 static pressure.Thestandard direct drive motor will give the desired airflow at a rated bhp of 0.73 and 951 rpm.

20 RT-PRC023-EN

Selection Procedure

Dehumidification Selection

Note: Dehumidification selection procedure is the same for both electric heat (THC) and gas heat(YHC) models).

OA ConditionsPart load day and raining68°F db67°F wb95% RHRA conditions75°F db63°F wb

Step 1:

Determine the mixed/entering air condition (MA)

MA = (% outside air*outside air dry-bulb temperature) + (% return air*return air dry-bulbtemperature)

MA = (0.40*68°F) + (0.60*75°F)

MA = 72.20°F db

Repeat for wet-bulb temperature (wb).

MA72.2°F db64.6°F wb

Step 2:

Determine the additional static pressure drop for a reheat unit

Table 145, p. 186 shows a static pressure drop of 0.13” for the reheat coil and an additional 0.08 forthe mandatory 2” pleated filters required when ordering the dehumidification option.Total staticpressure =

.34 + 0.08 + 0.13= 0.55

Do not forget to also add any additional static from other accessories.This selection does notinclude additional accessories.

Table 101, p. 146 (airflow table for 5 ton downflow unit) indicates that a standard motor and driveis needed for this airflow and static pressure range.

Step 3a:

Determine leaving evaporator temperature (SA’)

Leaving EvaporatorTemperature = SA’

Utilizing the manual Cooling Capacity selection method as previously described, find the leavingevaporator temperatures with the formula:

Temp = gross sensible orgross latent coolingcapacity in Btuh________________(cfm) (1.085)

RT-PRC023-EN 21

Selection Procedure

Subtract your sensible temp from the entering db and latent temp from the entering wb todetermine the leaving evaporator db & wb (temperatures without the addition of fan heat).

52.7°F db52.7°F wb52.7°F dp

Step 3b:

Determine leaving unit temperature in standard cooling mode

Repeat Step 3a substituting net sensible or latent capacity for gross sensible or latent capacity tofind the leaving unit temperature including fan heat.

53.7°F db53.1°F wb

Step 4:

Determine reheat temperature rise

Using the leaving evaporator temp (SA’), go to Table 150, p. 191 and determine the reheattemperature rise for that particular cfm: 19.0°F db

Note: Reheat temperature rise is based on supply airflow and leaving evaporator coiltemperature.

Step 5:

Determine leaving unit sensible temperature with reheat active (SA)Reheat temperature (obtained in step 4) + (SA’ + fan heat) = SA

(SA’ + fan heat) = leaving unit temperature in standard cooling mode from step 3b.

19.0°F db + 53.7°F = 72.7°F db

SA=72.7°F

Since reheat adds only sensible heat, the dewpoint temperature will remain constant so follow thedewpoint temperature line across the psychrometric chart to find the new wb temperature.

60.5°F wb52.7 dp49.9% RH

If the space relative humidity is equal to or above the space relative humidity setpoint, theDehumidification option will:

• Energize compressor or both compressors (2 stage compressor units).

• Hot gas reheat valve is energized and hot gas is diverted to the reheat coil.

• Dehumidification/reheat is terminated when space humidity is reduced to 5% below relativehumidity setpoint.

At MA air enters the RTU.The RTU filters, cools, and dehumidifies the air as it moves through theevaporator coil.Air leaves the evaporator coil saturated at the preset dew point condition (SA’) andis reheated by the hot gas reheat coil to deliver 72.7°F (SA) supply air to the space.
