BACKGROUNDReznor was founded in 1888 to manufacture the “Reznor”reflector heater, which used a luminous flame gas burnerdeveloped by George Reznor. This technological break-through was an immediate success and hastened the ex-pansion of gas heating in residential and commercial ap-plications. Technological development and innovation havebeen the hallmark of Reznor products through the years.The development of the forced air gas unit heater, the modu-lar Thermocore® heat exchanger, and the high-efficiency,V3® Series unit heaters have kept Reznor products at theforefront of technological advances in commercial and in-dustrial gas heating. As a result of this pioneering role inthe heating, makeup air, and ventilating equipment fields,the products offered today are the most advanced in engi-neering design to satisfy a wide variety of applications.

FACILITIESReznor® heaters were first manufactured and sold in Mer-cer, Pennsylvania (70 miles north of Pittsburgh) in 1888.Over the years, the company has grown and expanded.Today, with sales worldwide, Reznor products are beingmanufactured at facilities throughout North America andEurope.

MAPS® II OVERVIEWModels RCA, RDCA and RECA systems are specifically designedfor conditioning 100% outside or mixed air (outside and returnair).

Reznor Reheat Options:Reznor offers two reheat options.

1. Models RDA, RDDA and REDA systems use a dedicatedrefrigerant system that pre-cools the incoming air under the low-est dehumidification or cooling demand, while providing continu-ous reheat. Because the refrigerant system was optimized for re-heating versus cooling, the reheat system is rated in the heatingmode similar to a conventional heat pump.

2. Model RCA, RDCA and RECA units rated below 13 tonscan be specified with a supplemental reheat coil that providesreheat under medium or high dehumidification demand. Reheat isaccomplished by subcooling liquid refrigerant an additional 40 to50 degrees. Additional subcooling of the refrigerant increases de-humidification capacity while adding reheat.

Reheat Application Overview:In conventional systems, dehumidification occurs by chilling theair below a desired dewpoint. This typically means a 55°F drybulb leaving coil temperature (50% Rh at 75°F).

100% outside air dehumidification will require reheat when the55°F supply air temperature causes over-cooling of the space andincreased space relative humidity.

Specifying the quality (reheat availability under all load condi-tions), control of reheat (staged or modulating) and selection ofthe appropriate reheat system requires a working knowledge ofthe refrigeration cycle and HVAC system design. Considerationsfor the reheat system typically fall into three application types:

Constant Reheat - Applied where the space sensible and latentloads are small in comparison to the outside air load.

When the outside air load dominates the space load, a neutral air(continuous dehumidified air delivered between 70° and 75°F) ap-proach may be preferred. Typical applications include corridorsand locker rooms.

Variable Reheat - Applied where the space sensible or latent loadsvary in comparison to the outside air loads.

Variable sensible heat gains (solar, electric loads, occupancy etc.)affect the amount of reheat required to maintain space tempera-ture and relative humidity. If the equipment treats both outside airand maintains space temperature (a sole source unit), a variablereheat system will be required. Typical examples include surgicalrooms and “clean” rooms.

No Reheat - Applied where the space sensible load is constantand much greater than the outside air load. Typical examples in-clude motor and telecommunications centers .

Dehumidification Model Description:The Models RDA, RDDA and REDA are only applicable in cli-mates where dehumidification is required. Typically, this repre-sents geographical areas that see a 60°F dewpoint frequency greaterthan 400 hours per year. To illustrate the performance, comparethe performance of a cooling-only Model RCA (FIGURE 2) tothe cooling/dehumidifying Model RDA (FIGURE 3) at 95°/78°Fdry bulb/wet bulb.

The dehumidification unit Re-Heat PumpTM system uses a basicheat pump refrigeration circuit for dehumidification and reheat.Evaporator capacity is a small part (approximately 15-20%) of thetotal design capacity, allowing continuous operation at low loads(between 55 and 60°F ambient dewpoint). The re-heat pumpTM

system precooling evaporator coil is installed upstream of the mainevaporator coil, and the re-heat pumpTM condenser coil is in thedownstream position. The upstream precool coil tempers outsideair and lowers wet bulb depression of the air entering the mainevaporator coil (86.4/75.3). Heat removed from the precool coil isrejected to the downstream reheat coil (71.2/61.5 including com-pressor and fan heat of compression). In this mode of operationthe system is configured as a stand-alone neutral air unit whichconditions only the outside air to the building. If the main evapo-rator coil were removed, the refrigeration system would resemblea standard residential dehumidifier.

Since the dehumidification unit refrigeration circuit is indepen-dent of the main evaporative cooling coil, performance is rela-tively constant. This translates into ease of commissioning andverification of the Re-Heat PumpTM system performance un-der mild or extreme conditions. Other package systems that usehot gas reheat must maintain higher than needed condenser headpressures for reliable operation and adequate reheat. Under lowload conditions, poor performance of hot gas reheat and subcoolingreheat systems can be caused by compressor unloading. Service,diagnosis, and performance of hot gas reheat systems can be diffi-cult to verify at conditions other than design.

The Model RDA Re-Heat PumpTM downstream reheat (con-denser) coil provides a nominal 10 to 17 degrees of “reheat” tothe supply airstream. This temperature rise is accomplished withhigh compressor COP’s and low air pressure drop coils. For equiva-lent reheat performance, other technologies, such as heat pipesor flat plate heat exchangers may have greater than ten timesthe air pressure drop of the Re-Heat PumpTM coils.Additionally, performance of the heat pump is independent of themain cooling coil, while wrap around heat pipes or flat plate heatexchangers require an active cooling coil for energy transfer. Atpart load, the reheat pump can operate in a stand alone mode toprovide both dehumidification and reheat.

While the dehumidification unit compressor consumes additionalenergy during dehumidification modes, the year round benefit ofreduced fan energy will result in lower annual energy costs.

Model RCA, RDCA or RECA withSubcooling Reheat Coil Option:A subcooling reheat coil option is available on non-dehumidifica-tion systems up to 13.5 tons. The dual circuited reheat coil can bestaged with compressors in a 1/3 – 2/3 sequence. If reheat is en-abled and the dehumidification or cooling demand is high (bothcompressors enabled), dehumidification capacity can be increasedup to 15% (See FIGURE 4 Subcooling Reheat Coil PerformanceTable). The added capacity is a major benefit of applying asubcooling reheat coil. Typically it has the lowest first cost of anyconventional reheat system.

Applications:The subcooling reheat coil option is typically applied in conjunc-tion with standard HVAC units and a system with variable reheatrequirements. Reheat performance under a low cooling or dehu-midification demand may be compromised (if only one compres-sor is enabled, the available reheat is reduced by the same amount).However, if a relatively constant space sen-sible load is available and episodes of in-creased space relative humidity are accept-able, the subcooling reheat coil can be a use-ful design alternative. Examples includekitchens, labs, and any application where tem-pered outside air is introduced into the returnof a conventional HVAC unit. Care shouldbe exercised when applying this unit in a con-stant reheat application. While the supply airmay be dehumidified, the lack of space heatgains can cause over-cooling and increasedspace relative humidity.

50% Load - 65°F Dewpoint· One compressor or unloader is disabled to

prevent possible freezing and temperaturecontrol problems. Disabling the compressorreduces the available reheat.

· The independent Re-Heat PumpTM circuit hasavailable reheat at the reduced load to holdthe space setpoint.

25% Load - 60°F Dewpoint and Ambientbelow 65°F· The lower evaporator load opens the hot gas

bypass valve causing additional loss of hot gasreheat. Refrigerant reliability can be compromisedunder these conditions.

· The Re-Heat PumpTM circuit available reheat is slightlycompromised as the evaporator load is reduced. . . so is the heat of rejection.

SOLUTION: CSSHG = (7,500 + 2,000) = 9,500 Btu/Hr

Required Reheat = 75 – [9,500 ÷ (1800 x 1.08)] – 55= 15°F

The quality and control of reheat is influenced by room sensible heat gains at both design and part load conditions. In thisexample, the dehumidification demand is small, yet the refrigeration equipment should continue to provide 15°F of reheat toprevent over-cooling and increased space relative humidity.

Determining Space Reheat Requirements:The amount of reheat depends on the temperature leavingthe cooling coil and the minimum available space heatinggain at part load conditions. A simple approximation isshown below:

REHEAT REQUIRED (°F) =[SP – [CSSHG ÷ (CFM x 1.08 ADF)] - LA

SP = Room setpoint °FLA = Leaving coil temperature (°F) to provide design

dewpointCSSHG = Constant space sensible heat gains at low

load (BTU/HR)CFM = Room airflow rate (cubic ft/min)ADF = Air density factor (1.08 is sea level)

EXAMPLE: A room requires continuous dehumidification of 100%outside air down to 60°F ambient dry bulb temperatures. For pur-poses of estimating reheat requirements in dehumidification mode,assume no solar influence and identify the constant sources of spaceheat gains:Outdoor Dry Bulb ........60°FOutdoor Dewpoint .........60°FElevation ........................Sea LevelSolar Loads ....................0Skin Loads .....................0People ............................0Lighting (Btu/hr) ...........7,500Equipment (Btu/hr) ........2,000Ventilation (cfm) ............1,800

Room Air Flow Rate(CFM): 1,800 CFM

Room Setpoint (SP):75°F and 50% RH(55°F Dewpoint)

Required Leaving CoilTemperature °F (LA): 55°F

APPLICATION NOTES:MAPS II Systems are replacement air systems which treat up to100% outside air. Models RCA, RDCA and RECA can be appliedin a variety of geographical locations and conditions.

Models RDA, RDDA and REDA include a specialty reheat sys-tem and are targeted for temperate and humid climates. These unitsare typically applied as a neutral air system that provides dehu-midified replacement air between 70° and 75°F.

The following topics summarize typical equipment considerationsfound in specifying replacement air systems:

Zone Outside Air Changeover RatesWhen evaluating the suitability of staged capacity control, the out-side air changeover rate to the zone should be calculated. Use theformula listed below.

High air changeover rates may require special control sequences,air distribution design, and cooling-heating modulation controlsversus step control. As a guideline, modulation should be evalu-ated when the changeover rate exceeds 8 ACH (1 outside air changefor every 7.5 minutes). Since heating design temperature differ-ence is typically greater than cooling, modulation of the heatingsystem may be more critical.

Design Temperature DifferenceAs design extremes increase, staging or modulation of equipmentcapacity becomes increasingly important. Examining the loweststage or step of equipment capacity relative to the lowest load con-dition can indicate if capacity modulation is required.

System TypeGenerally products that deliver 100% outside air quantities fallinto one of three basic system types. They include:

Formula for Calculating the Outside Air Changeover Rate:Outside Air Changeovers per Hour (ACH) = [Outside Air Qty (CFM) x 60] ÷ Zone Volume (cubic feet)

· Neutral Air - Outside air is cooled, dehumidified, and heated toroom conditions (70 to 75°F).

· Tempering Air - Outside air is cooled and mixed with condi-tioned return air.

· Sole Source - Conditions both outside air and the internal build-ing loads.

Identifying the system type can aid the designer in evaluating theappropriate equipment for each application. A more detailed dis-cussion can be found in Application Bulletin RZ-T-PC.

Hot Gas BypassThe addition of hot gas bypass capacity modulation should be evalu-ated for most high outside air applications. The wide variation ofoutside air conditions can result in a low cooling demand relativeto the available equipment capacity. Hot gas bypass reduces ex-cess evaporator capacity and extends compressor operation as op-posed to cycling (ON/OFF) excess capacity.

If closer control of discharge air temperature is desired, each MAPSII system can be specified with hot gas bypass on both the lead and2nd stage circuit. The MAPS Software Calculator can confirm lowload operation and the necessity for hot gas bypass modulation.

Filters100% outside air systems typically require more frequent inspec-tion than return air systems. Pleated filters are preferred only ifexisting makeup air installations have shown no evidence of filterdegradation due to heavy moisture loading. Permanent filters maybe preferred in ASHRAE defined humid climates or areas withheavy rainfall. Pleated filters are recommended for any environ-ments with a history of particulate loading and coil cleaning. Both2” and 4” filters are available. 4” filters have the advantage of addedsurface area and lower velocities (reduced pressure drop).


Page ___________ of ______________

Outdoor Ambient Changeover ControlsStaging or sequencing cooling and heating capacity steps in con-junction with outdoor conditions can reduce unwanted compres-sor or heating operation. All models have controls that includeuser defined outdoor setpoints to permit equipment capacity stepsbased on a combination of outdoor dry bulb and dewpoint. Heat-ing permissive control is based on outdoor dry bulb temperature.Cooling and dehumidification permissive control can be based onboth outdoor dewpoint, enthalpy and dry bulb temperature.

Outside Air IntakeReplacement air systems should typically be specified with a mo-torized outside damper and interlocking safety to ensure the damperis opened prior to enabling the supply fan (when no return air pathis connected). Building codes and national standards may requirea motorized damper for specific airflow ranges. The location ofthe outside air intake should comply with the requirements ofASHRAE 62.1999. A transition is required between the primaryfilters and outside air inlet to provide uniform velocities acrossfilters and cooling coils. The transition section should be designedto manage any moisture carryover by allowing condensate to drainoutside the roof curb perimeter.

APPLICATION NOTES: (cont’d)PerformanceReplacement air rooftops are designed for up to 100% outside air.Unlike traditional return air systems, entering cooling coil tem-peratures vary widely, resulting in a different equipment designapproach. This includes cooling coil circuiting design, capacitystaging, component selection and control sequences to optimizeperformance under both design and part load conditions. Becauseof the specialty nature of replacement air systems, there are nobenchmark performance standards for minimum equipment en-ergy efficiency ratings (EER’s).

However, other standards or test procedures may be referenced toensure an optimum approach to equipment design. Examples in-clude the latest ASHRAE 90.1, ASHRAE 62.1, ANSI Z83.8, AIA-15733, and ARI 410/540 standards.

Software SelectionVerification of equipment performance should precede equipmentselection. Use the Reznor MAPS Calculator Software Program toconfirm performance for both heating and cooling modes.

Heat Section Supply Gas Pressures• 3-stage control requires a minimum of 5.5” w.c. natural gas or 11” w.c. propane gas.

• Optional 6:1 control requires a minimum of 6” w.c. natural gas (6:1 control is not available with propane gas.) (Patent Pending).

ENGINEERING/APPLICATION INFORMATIONControls

FIGURE 6 -Controls

(Refer to ControlSummary Section for optionselection.)

Reznor provides three levels of control. Level 1 allows basic control features. Level 2 ex-pands level one features to include additional application capabilities, alarm, unit status fea-tures and expanded return air options. Level 3 provides networking capabilities with a cus-tomer supplied Building Automation System (BAS).

Each Level of control includes a unit mounted DDCcontroller. The controller hardware includes user inter-face options for selecting control features, setpoint ad-justments, displaying unit temperatures and unit statusvia keypad inputs. Time clock and open protocols com-munication cards can be added to each controller.

Control Application Reznor MAPS II rooftop controllers are specifically programmed for high outside air applica-tions. To meet a variety of applications each controller can be specified with one of two basicPLC routines. The controller algorithm specified is dependent on system application.

Application -01 - Discharge Air Control with Outside Ambient Override

Application -02 - Space Temperature Control with Discharge Air Reset Control

Application - 01 is specified when the rooftop is applied to condition only the outside air load.Unit operation (heating/cooling or dehumidification modes) is based on the outside air condi-tions entering the unit. This typically restricts application #1 to 100% outside air treatmentwith only indirect control of space temperature. Typical applications include corridor ventila-tion (where sensible loads can be minimal) and kitchen replacement air (where sensible loadsare exhausted from the space). Limited space temperature control can be achieved by addingwall mounted thermostats which reset the discharge air control during occupied or unoccu-pied modes (when equipped with return air dampers). Additional control applications includesystems integration with conventional equipment. Application - 01 is shown in Figure 7 wherea dedicated 100% outside air unit is ducted into the return or outside air intake of an existingrooftop unit.

ENGINEERING/APPLICATIONINFORMATION(cont’d)

Application - 02 is specified when the rooftop is applied to treat both the outside air and zoneloads. Unit operation (heating/cooling or dehumidification modes) is based on the space tem-perature. Application -02 can be specified for both 100% outside air units and high mixed airpercentages (35% to 100% outside air). If the rooftop is being applied as a “sole source” unit,gas heat 6:1 modulation and compressor reheat options (where dehumidification is required) arerecommended. Figure 8 shows Application - 02 being utilized in a sandwich deli shop.

Control Application (cont’d)


Page ___________ of ______________

Zone Temperature SensorThe field installed temperature sensor is requiredwhen applied with Application – 02. The zone tem-perature is used to reset the unit discharge airsetpoints upon a call for heat or cooling. For treat-ment of 100% outside air, zone outside airchangeovers per hour (ACH) should be within 8ACH to match the available compressor cycle rates.If zone air is not recirculated or mixed within the space, the mount-ing location of the zone sensor becomes increasingly important. Inmany kitchen make up air applications, the sensor is used as anupper and lower limit for the cooling and heating modes or simplyas an unoccupied control. Additional features include a standardoccupied/unoccupied temperature override and a status/alarm LEDindicator with 3 stage heating units.

Relative humidity Control (Option,CL47)Relative humidity control can be applied at the spacelevel, however all Reznor reheat systems areequipped with an outside air humidity control se-quence which provides constant dehumidificationabove an outdoor dewpoint (the outside air is typi-cally the dominant moisture source). When relativehumidity control is applied at the space level it is typically appliedin return air applications where internal moisture loads are rela-tively high or variable (such as an unoccupied mode).

The Relative humidity controller can be applied stand-alone or inconjunction with the remote console. The RH controller will cyclereheat based on space relative humidity. Reheat is disabled if thespace calls for active cooling.

Outside Air Relative HumidityTransmitter (Option DT5)This option combines a relative humidity transmit-ter (standard on RDDA and RCDA models withsubcooling reheat coil) and the unit controller to stagecooling capacity based on a calculated outdoordewpoint or enthalpy. Sequencing of equipment ca-pacity based on outdoor conditions can minimizeunwarranted equipment operation.
