®OPTIONAL COOLING COIL CABINETWITH DX OR CHILLED WATER COILFor use with Models(C)RGB, RPB, (C)RGBL, or RPBLPage _____ of _____CUSTOMERCQSAGENCYCONVERGENTQUALITY SYSTEMPRODUCTPROCESSSTART-UPWARRANTYDescription/ApplicationIndirect-fired packaged Reznor heating/makeup air systems, ModelSeries RGB, RPB, RGBL, RPBL, PGBL and SSCBL, are available with anoptional cooling coil cabinet that houses a large finned surface refrigerant(DX) or chilled water cooling coil. Cooling coils are available in capacitiesfrom 3 to over 40 tons (36 to 480 MBH). Depending on the size of thesystem, the cabinets accommodate coils with a finned surface area from 4 to15 square feet. Large finned surface areas aid coil performance by reducingface velocities, lowering coil pressure drops, and increasing cooling capacity.Cabinets are fully insulated with weatherproof construction for outdoorapplication. Standard construction is single-wall 20 gauge galvalume steel.Optional double-wall cabinet construction is available. The cooling coil cabinethas a drain trough for positive drainage under all operating conditions incompliance with ASHRAE Standard 62-1989. The drain trough is providedwith a 1" FPVC connection on the exterior of the cabinet. Each side of thecooling coil cabinet has easily removable door panels for routine coil inspectionand cleaning. For down discharge, an optional downturn plenum cabinetwith or without discharge dampers is available.Refer to Tables 6 through 9 for performance data under entering airconditions of 80°F (drybulb) / 67°F (wetbulb) and 95°F (drybulb) / 75°F(wetbulb) The performance data is certified in accordance with ARI Standard410.For coil capacities not outlined in these tables, special coil requirements,or indoor cabinet installation, contact your Reznor Sales Representative.Cooling Coil Selection ProcedureSelecting the proper cooling coil is vital to air handling equipmentperformance and cost. The correctly sized coil provides the desired dehumidificationand sensible cooling under all possible internal and externalloads that the building may experience. In order to properly select the coilcapacity, a detailed internal and external load analysis must be performed.Caution must be taken to ensure that the percentage of outside air broughtinto the building meets current codes. The percentage of outside air for mostapplications is approximately 25%. Some current codes require greater percentagesof outside air, up to 100% for densely populated structures wherecontaminants become a significant health risk, such as schools. The currentASHRAE recommendations on proper percentages of outside air can befound in ASHRAE Standard 62-1999 “Ventilation for Acceptable IndoorAir Quality”.Review the coil performance tables for general capacity data at standardoutside air (95°/75°F) and return air (80°/67°F) conditions. The preferredmethod of selection is to use the Reznor Coil Selection Software. If youdo not have a copy, contact your local Reznor Sales Representative.ControlsControls are not factory supplied with the coils. Controls include allcondensing related equipment -- thermostatic expansion valves (TEV), auxiliaryconnections for hot gas bypass, and hot gas bypass or liquid injectionvalves. See your local Reznor Sales Representative for recommended TEV's.Coil distributor details are in Table 4.Features● Weatherized, insulated cabinet is an integral part of a Reznor ® heating/makeup air system (with either a factory-installed DX or chilled watercooling coil)● Single-wall cabinet construction (double-wall option available)● Cabinet includes access panels for easy coil inspection or cleaning● Available for standard refrigerant (DX) or chilled water coil~ Capacities from 3 to over 40 tons (36 to 480 MBH)~ 2, 3, 4 or 6 row coils with 6, 8, 10, 12 or 14 fins per inch (fin thickness.0075") are standardAdditional Coil Options:~ Phenolic coatings~ Copper fins~ Stainless steel casingForm RZ-NA-C-PO Page 38Table 1: Cabinet Option DesignationsCode DescriptionAU2 Cooling Coil Cabinet for a Chilled Water CoilAU3 Cooling Coil Cabinet for a DX CoilAU11 Cooling Coil Cabinet for a Chilled Water Coil plus a DownturnPlenum CabinetAU12 Cooling Coil Cabinet for a Chilled Water Coil plus a DownturnPlenum Cabinet with 2-Position Discharge DampersAU13 Cooling Coil Cabinet for a DX Coil plus a Downturn PlenumCabinetAU14 Cooling Coil Cabinet for a DX Coil plus a Downturn PlenumCabinet with 2-Position Discharge Dampers

Follow thesteps below before submitting a Coil Option Specification Request Form.The preferred method of selection is to use the Reznor Coil SelectionSoftware. If you do not have a copy, contact your Reznor Representative.Steps:1. Enter the Table for your cooling application – Refrigerant Coils, R22 -Table 6 or 7; Chilled Water Coils - Table 8 or 9.2. Choose the table which best matches your entering air conditions. Tables6 and 8 are for the condition of 80°F db / 67°F wb. This is a standard coilrating condition for return air applications. All Reznor coils are rated toARI Standard 410. Tables 7 and 9 are for the condition of 95°F db / 75°Fwb. This is an accepted general condition for 100% outside air applications.If your design condition is different from these or your operatingparameters vary from those specified, you can only estimate performancefrom these data tables.3. Find your furnace model in the left-most column of the table.Form RZ-NA-C-PO Page 43Page _____ of _____Notes for Tables 5A and B:1) Calculate Coil Face Velocity as : [Airflow (scfm [sM 3 /hr]) / Finned Coil Surface Area (sq.ft. [M 2 ])]2) A general rule of thumb for required airflow is 400 scfm (680sM 3 /hr) per ton of coolingfor return air applications. This value will be much less for outside air applications.3) To avoid the possibility of condensate blow-off, the coil face velocities should not exceed550 sfpm.4) Conversion to standard air flow is required above 1500 ft. To convert from actual airflow(acfm) to standard airflow (scfm), see Conversion to Standard Airflow.5) If the coil cabinet is being ordered with an indoor unit (Model SSCBL or PGBL), contactyour Sales Representative for details on the required field-supplied transition.4. The table contains capacities at the minimum and maximum suggestedairflow for each furnace model, see column 2.Your airflow in Standard CFM (SCFM) should fall within this range. SeeConversion to Standard Airflow to determine scfm from the actualairflow (ACFM). ACFM should be used when selecting fan and motorrequirements.For coil selections the important parameter is not the volume of air over thecoil, but the mass flow over the coil. This requires knowledge of thevolume flow at “standard conditions” (SCFM).5. Determine the maximum capacity available from a specific coil by enteringthe Table and finding the total capacity (mbh) for a 6 row, 12 fins per in(fpi) coil at maximum airflow (scfm). If your application if less than thepublished capacity for the design conditions, use the Selection Requirementssection to complete your request form. If your application requiresa coil capacity greater than determined above, you may require a largerfurnace and accompanying coil cabinet to achieve the necessary coil size.Your Sales Representative will be able to assist you in this selection.

®Using the Coil Performance Tables (Tables 6, 7, 8, and 9) cont’dPage _____ of _____Example : (Refrigerant Coil)Furnace model ....................... RPB-200Design conditions ................. 90/70°FApplication airflow ............... 3500 scfmCapacity required .................. 120 mbhEvaporator Temperature ........ 45°FLiquid Temperature ............... 100°FStep 1 Design is 90/70°F. Be conservative, enter the table for 80/67°FStep 2 Furnace Model is a size 200Step 3 Determine the maximum capacity for a size 200 cabinet = 184 mbhSince the requirement of 120 mbh falls within the tabulated capacity of 184 mbh forentering conditions of 80/67°F, a standard coil will meet the application requirements.Complete a Coil Option Specification Request Form (see page 12) and submit it to yourReznor Sales Representative.Table 6.

Required R22 Refrigerant Coil InformationFor refrigerant coils the following additional information must be supplied;● Evaporator temperature, °F● Liquid temperature, °F● Consult the factory for special circuiting or refrigerantsD. Special RequirementsThe following special options are available on all coil types and sizes.● Phenolic coatings● Stainless steel coil casing material● Copper finsNote: For special requirements not listed here, contact your Reznor SalesRepresentative.E. Entering Air ConditionsDesign dry bulb and wet bulb temperatures must be considered whenchoosing a coil. For applications using a percentage of outdoor air, thecondition of the "mixed air" entering the coil can be calculated as shown inthe following steps.● Mixed Dry Bulb TemperatureThe mixed dry bulb temperature is a simple arithmetic average of thereturn and outside air temperatures weighted by the percentage of the standardcfm in each air stream.Example:1000 acfm of outside air @ 95°F (db) is mixed with 5000 acfm ofreturn air @ 80°F (db). The elevation is 2000 ft. above sea level.Step 1Determine the standard airflow (scfm) by adjusting the actual (acfm)with temperature, F t, and elevation, F e, correction factors; see Tables 10 and11 to determine the value of these factors.Correction Factors for Outside Air --F t= 0.05 andF e= 0.08Standard airflow = acfm / (1+ F t+ F e)1000 / 1.13 = 885 scfmCorrection Factors for Return Air --F t= 0.02 andF e= 0.08Standard airflow = acfm / (1 + F t+ F e)5000 / 1.10 = 4545 scfmTotal supply airflow = 885 + 4545 = 5430 scfmStep 2The mixed air dry bulb temperature is the average as shown below.{(95 x 885) + (80 x 4545)} / 5430 = 82.4°F● Mixed Wet Bulb TemperatureThe mixed wet bulb temperature must be determined using a psychrometricchart or Table 12.Example1000 acfm of outside air @ 75°F (wb) is mixed with 5000 acfm ofreturn air @ 67°F (wb).Step 1Using Table 12, determine the enthalpy of each air stream.Outside air at 75°F (wb) = 38.6 Btu/lbReturn air at 67°F (wb) = 31.6 Btu/lb.Step 2The enthalpy of the mixed airstream is determined by calculating theaverage as shown below.{(38.6 x 885) + (31.6 x 4545)} / 5430 = 32.7 Btu/lbStep 3The mixed airstream wet bulb temperature can be found in Table 12corresponding to the mixed enthalpy value of 32.7 Btu/lb.T (wb) = 68.3 °F● Entering Air ConditionEntering air condition is typically written as T(db) / T(wb). In the aboveexample, the mixed air condition is 82.4°F / 68.3°F.F. Conversion to Standard AirflowA fan must be selected using airflow calculated at the actual conditionsof operation. Since a fan is a “constant volume” device, the actual CFM(ACFM) is required for analysis and properly determining motor requirements.To specify a coil, it is important that the airflow be converted intostandard CFM (SCFM) or air at a density of 0.075 lb/ft 3 . Cooling andheating coils must be selected using SCFM. Up to an altitude of approximately1,500 feet above sea level, very little error is introduced if ACFM issubstituted in the selection of a coil. For altitudes that exceed 1,500 feetabove sea level, the coil should always be selected using SCFM. The relationshipbetween ACFM and SCFM is shown by the following equation:SCFM = ACFM x (Actual Density / 0.075). From this equation it is obviousthat the relationship between SCFM and ACFM is dependent upon air densitywhich is a function of temperature and elevation. Tables 10 and 11contain correction factors for conversion from ACFM to SCFM.The factors are used in the following manner: SCFM = ACFM (1+F)where F may be a correction factor for temperature (F T), or elevation (F E), orboth (F E+ F T).Example: A cooling coil must be selected for an application that is 3,500ft. above sea level with entering air of 90°F dry bulb. The blowerdelivers 10,000 ACFM. What is the SCFM seen by the coil?Answer: For 90°F the temperature correction factor in Table 10 is 0.04.At 3,500 feet, the elevation correction factor from Table 11 is 0.14. Theanswer is found by adding the two correction factors and dividing asshown here.SCFM = 10,000 ACFM / (1+0.14+0.04) = 8,475 SCFMTable 10.
