PERFORMANCE

For unit performance under specific conditions pleasecontact you FHP Manufacturing representative.

TYPICAL APPLICATIONS

CONSTANT VOLUME AIRFLOW

MB units are ideally suited to air condition large spacesin offices, and shops providing a total climate controlsystem. The units may be applied on a floor by floor

basis or serve a specific area. Unit control isaccomplished by sensing the space or return airtemperature and staging the unit based on the controlset point.

VARIABLE AIR VOLUME

MB units are available with a factory installed variablefrequency drive package for modulating the airflow inresponse to changes in the system duct staticpressure. VAV units have the ability to controltemperatures in areas of different loading such as theinterior and exterior zones of a building. Only thevolume of air that is required to satisfy the space loadis delivered providing significant savings in energy.Typically the system is designed to provide supply airat a constant temperature through the control ofdischarge air temperature. VAV terminals in the spacemodulate open or closed as the load varies increasingor reducing the airflow to satisfy the demand.Temperature reset based on return air temperature isalso available.

DEHUMIDIFICATION

Indoor air quality is a major concern in the design andoperation of today’s buildings. Humidity levels, if notproperly controlled, can play a major role in thedevelopment of fungal growth which is a major causeof the problem. Controlling the space temperaturealone will not assure proper humidity control. To bringthe humidity to an acceptable level requires cooling theair to a relatively low temperature, which can result inuncomfortable conditions within the space. The air,after dehumidification, needs to be reheated to avoidthis problem. Typically electric heat has been applied todo this but is probably the most expensive optionadding significantly to operating costs. An alternativewould be to use hot water if it is available. Again thisrepresents an additional operating cost. Additional hotwater piping will be needed, increasing initial costs. MBunits offer a factory installed hot gas reheat option thatuses the hot refrigerant gas to reheat the air. All of theheat of rejection is not used to reheat the air so thereis a net cooling effect but not enough to createuncomfortable conditions within the occupied space.Hot gas reheat operation is controlled through spacehumidity levels so only operates when needed.

Further information on MB units for specificapplications is available by contacting your local FHPrepresentative.

MB SERIES 5

The controller is capable of monitoring and controllingtemperatures, static pressure (VAV applications),humidity, fluid flow and airflow as required and whenordered with the appropriate sensors.

The standard unit controller is configured for constantvolume, return air control. Optional control strategies areavailable, for example, humidity/reheat control andvariable air volume discharge air temperature control withreturn air reset. All safety inputs are monitored and alarmsignals can be generated. The controller willautomatically restart the machine following a non-criticalalarm condition, not taking the unit off line unless thesame alarm has occurred twice within an adjustable timeperiod. Nuisance shut down of the unit is avoided whilestill providing protection against possible equipmentfailure. A record of faults and time of occurrence is keptin the controller to facilitate trouble shooting and servicingof the unit. A systems time clock is standard on all MCScontrollers enabling programming for daily operations.

All necessary sensors are factory provided, field installedfor application specific control strategy. The controller isconveniently located on the unit for easy reading andprogramming. A 2 line 16 character LCD displays alltemperature, pressure and control functions in easy toread English. Battery back up is standard to prevent lossof operating parameters during powerinterruptions/losses. A four layered printed circuit boardprotects the microprocessor from power surges or fasttransients across or over the lines. Please refer to the unitcontroller manual for further details

REVERSE CYCLE OPERATION

All MB series units are capable of operating in the reversecycle heat pump mode for efficient, cost effectiveheating. The MB series is the only self-contained heatpump unit in its class. This feature allows the designer totake full advantage of building diversity, transferringexcess heat from areas with a net cooling load to areasrequiring heating providing a truly energy efficient system.

HOT WATER COIL

Bolt on one or two row hot water coils for hydronicpreheat are available as a field installed option. Pleaseconsult factory with requirements for coil design andselection.

ECONOMIZER/FILTER BANK MODULE

Factory installed water-side economizer coils areavailable on all MB series units. The economizer packageconsists of full-face area multi-row copper tube,aluminum fin coils designed for low water-side pressuredrops. A 3-way motorized ball valve is included in thepackage for water flow control. The valve includes amanual clutch option for field over-ride capability while anoptional minimum positioner for the valve is also

available. The economizer may be controlled through theoptional MCS controller which senses entering fluidtemperature to the unit and opens the valve to allow flowthrough the economizer coil and condenser in series. Innormal operation, flow is through the condenser only.The set point is adjustable between 45 ºF and 70 ºF in thecooling mode. A heating economizer cycle is alsoavailable for heating utilizing high temperature loop fluidor high temperature fluid from a heat exchanger that is ona hot water hydronic loop. The package has a 400 PSIGdesign working pressure and is pressure tested for leaksat the factory.

FILTERS

All MB series units come with standard 4 inch 30%efficiency pleated filters. Optional 65% 4 inch pleatedfilters are available. Filters are removable from the sidesof the frames through filter access panels. Throw awayconstruction filters should be field installed to protect themain filters during the construction period.

FAN MODULE

MB units contain either one or two forward curved high-pressure class II fan assemblies depending on the modelsize. The fans are double width, double inlet weldedassemblies statically and dynamically balanced. The fanmodule is isolated from the main module by the use ofrubertex gaskets providing excellent vibration isolationand quiet operation. The modules are bolted togetherwith 1/2 inch diameter bolts and locking nuts. Each fan ispowered by it’s own motor and drive assembly. Motorsare mounted on individual motor platforms for stableoperation and belt tension adjustment. All assembliesinclude 150,000-hour re-greaseable pillow blockbearings with large diameter solid steel shafts for hightorque/speed operation.

MB SERIES4

DESIGN FEATURES:

Unit Construction

The FHP MB series is available in two basicconfigurations:

VH CONFIGURATION

The VH design concept is to provide a unit that willfacilitate on site handling and can be installed in locationsdifficult to access. All units can be broken down intoseparate modules that can pass through a 36" widestandard door or service elevator. No refrigerant pipingrequires disconnection, maintaining circuit integrity.Water piping connections are made with the use ofheavy-duty bronze-bodied unions so no welding orbrazing is required in the field. Single supply and returnconnection to the unit are standard. This creative designallows the installer to transport and locate the modules inthe equipment room without the use of heavy-dutycranes or lifts. Building penetrations or interior wallpenetrations are not normally required on retrofit jobswhere space is at a premium. The 30 ton module can beeasily broken down into 3 separate modules - the fanmodule, main heating/cooling module and theeconomizer/filter bank. The 40 through 60 ton units canbe broken into 6 separate modules, two each aspreviously mentioned. Very few competitive equipmentmanufacturers have this capability.

VL CONFIGURATION

The VL is designed for those applications where there isa restriction in the height of the unit. In this model theblower is dropped into the main coil section reducing theunits overall height and increasing unit depth. Unit sizesMB480 through MB720 can be split into two sections fortransportation and access into the plant room.

FLEXIBILITY

The FHP MB series is available in cooling only or withreverse cycle heating with either constant or variable airvolume discharge to provide a highly efficient operatingsystem. Water-side economizer packages are availableto take advantage of free cooling. Optional field installedhot water coils provide preheating or heating. Hot gasbypass allows the unit to operate under a wide variationof conditions and the hot gas reheat option provides ameans of controlling humidity, a major concern in theinterior environment of a building.

UNIT PERFORMANCE

The units are available in four sizes from nominal 30through 60 tons.

Performance is with nominal CFM and rated inaccordance with ARI 320 conditions. Performancenumbers are gross.

CABINET, CASING AND FRAME

For heavy-duty structural support an internal angle ironframework is utilized. The angle iron members areattached using 1/2 inch bolts and locking nuts for easeof disassembly and re-assembly. The base-panassembly is constructed of 14 gauge galvanized steel.Exterior panels are made of 18 gauge, G90 galvanizedsteel providing protection against corrosion. All panelsare insulated with 1/2 inch thick dual density Neoprenebacked fiberglass insulation for thermal and acousticperformance. Insulation meets the erosion requirementsof UL 181. Base rails are provided to assist rigging theunit on site. All components are located for ease ofinspection and service.

Unit ConstructionThe FHP MB series is available in two basicconfigurations:

VH CONFIGURATIONThe VH design concept is to provide a unit that willfacilitate on site handling and can be installed inlocations difficult to access. All units can be brokendown into separate modules that can pass through a36" wide standard door or service elevator. Norefrigerant piping requires disconnection, maintainingcircuit integrity. Water piping connections are made

with the use of heavy-duty bronze-bodied unions so nowelding or brazing is required in the field. Single supplyand return connection to the unit are standard. Thiscreative design allows the installer to transport andlocate the modules in the equipment room without theuse of heavy-duty cranes or lifts. Building penetrationsor interior wall penetrations are not normally requiredon retrofit jobs where space is at a premium. The 30ton module can be easily broken down into 3 separatemodules - the fan module, main heating/coolingmodule and the economizer/filter bank. The 40 through60 ton units can be broken into 6 separate modules,two each as previously mentioned. Very fewcompetitive equipment manufacturers have thiscapability.

VL CONFIGURATIONThe VL is designed for those applications where thereis a restriction in the height of the unit. In this model theblower is dropped into the main coil section reducingthe units overall height and increasing unit depth. Unitsizes MB480 through MB720 can be split into twosections for transportation and access into the plantroom.

Please see unit drawings on pages 20 through 23 forunit dimensions.

humidity, a major concern in the interior environment ofa building.

UNIT PERFORMANCE




For heavy-duty structural support an internal angle ironframework is utilized. The angle iron members areattached using 1/2 inch bolts and locking nuts for easeof disassembly and reassembley. The base-panassembly is constructed of 14 gauge galvanized steel.Exterior panels are made of 18 gauge, G90 galvanizedsteel providing protection against corrosion. All panelsare insulated with 1/2 inch thick dual density Neoprenebacked fiberglass insulation for thermal and acousticperformance. Insulation meets the erosion requirementsof UL 181. Base rails are provided to assist rigging theunit on site. All components are located for ease ofinspection and service. Major components are out of theunits air stream to allow maintenance while the unit is inoperation. Service access is through the removal ofaccess panels located on the unit.

COMPRESSORS

All units utilize high efficiency scroll compressors. TheMB360 has two compressors while the MB480 throughMB720 units contain fourcompressors for efficient partload control, quiet operationand system redundancy.

Each compressor has its ownindependent refrigerant circuitand is protected by individualbranch fusing. Additionalprotection is provided bythermal overloads and high andlow pressure safety switches.Suction and discharge schradervalves are provided for manifoldgauge connections to facilitateservicing. Compressors aremounted on vibration isolators.

The entire condensing sectionis isolated from the air-handlingcompartment by the use of an

insulated bulkhead partition designed to minimize soundtransmission.

Externally equalized balanced port thermostaticexpansion valves are utilized for wide range refrigerantmetering control. Superheat shifts are minimal fromcooling to heating operation ensuring stable operation inboth the heating and cooling modes. All TXV’s arefactory set and are field adjustable for specific operatingconditions. Reversing valves are large bodied tominimize refrigerant pressure drop. Line voltagesolenoids are utilized to reduce transformer loading. Allrefrigerant components are accessible from the front ofthe unit for service and maintenance.

CONDENSERS (water to refrigerant heat exchangers)

All condensers are coaxial tube-in-tube for maximumheat transfer efficiency and performance. Inner watertubes are either copper or optional cupro-nickel withlarge internal diameters for reduced water-side pressuredrops. Outer tubes are steel, painted for corrosionprotection. All condensers are rated at 450 PSIGoperating refrigerant pressures and 400 PSIG water-side pressures. Condensers are individually leak tested.All condensers are chemically cleanable. Please consultthe factory for cleaning procedures. Units are designedfor single water supply/return connections with modulesbeing connected by the use of heavy-duty bronzeunions.


Evaporators are enhanced fin, rifled tube type formaximum performance. Large face areas ensure lowairside pressure drops and reduced face velocities toprevent condensate carry over and maximum moistureremoval.

Coils are either three or four rows deep depending onunit model and mounted in small area, sealed drain pansto inhibit condensate buildup levels.

All drain pans are galvanized steel with Archem typecoating for corrosion protection. Optional stainless steeldrain pans are available. Bottom outlet fittings in drainpans ensure free draining. Optional condensate overflowswitches are available.

Each refrigerant circuit is independently piped allowingpart load operation in the event of a component failure.Compressor/evaporator staging is such that airstratification is kept to a minimum. The lowerevaporators on each module are staged first to keepcoils wet and enhance condensate removal. In the eventof an evaporator failure only the individual coil need bechanged compared to the full face evaporators utilizedby some manufacturers.

ELECTRICAL

All units are completely wired and tested at the factoryprior to shipment. Wiring complies with NECrequirements and units are UL 1995 safety certified andlisted. Single point power supply is standard on allmodels. Each module has its own power blocksimplifying wiring in the field for knock down

Safety controls include the following:

• High pressure switches located in the refrigerantdischarge lines. One per refrigeration circuit.

• Low pressure switches for loss of charge protectionlocated in the unit refrigerant suction lines. One perrefrigeration circuit.

• Optional freeze protection sensor located on theleaving side of the water coil prevents unit operationbelow 35ºF. Freeze terminals must be jumpedtogether if the freeze sensor is not installed.

• Optional Condensate overflow protection sensorlocated in the drain pan(s) of the unit and wired tothe UPM board.

The UPM includes the following features:

• ANTI-SHORT CYCLE TIMER – 5 minute delay onbreak timer to prevent compressor short cycling.

• RANDOM START – Each controller has a uniquerandom start delay ranging between 270 through330 seconds.

• LOW PRESSURE BYPASS TIMER - The lowpressure switch is bypassed for 90 seconds aftercompressor start-up to prevent nuisance lowpressure lockouts during cold start-up in the heatingmode.

• BROWNOUT/SURGE/POWER INTERRUPTIONPROTECTION – a 20 millisecond window ismonitored for the above condition. Should any ofthese conditions be detected, the 5-minute delay onbreak timer and the random start timer delay areinitiated.

• MALFUNCTION OUTPUT – The controller has a setof wet contacts for remote fault indication.

• TEST SERVICE PIN – A jumper pin is provided toreduce all time delay settings to 5 seconds duringtroubleshooting or verification of unit operation.Note that operation of the unit in test mode can leadto accelerated wear and premature failure of theunit.

TESTING


PERFORMANCE



MB units are ideally suited to air condition large spacesin offices and shops providing a total climate controlsystem. The units may be applied on a floor by floorbasis or serve a specific area. Unit control isaccomplished by sensing the space or return airtemperature and staging the unit based on the controlset point.

VARIABLE AIR VOLUME

MB units are available with a factory installed variable

frequency drive package for modulating the airflow inresponse to changes in the system duct staticpressure. VAV units have the ability to controltemperatures in areas of different loading such as theinterior and exterior zones of a building. Only thevolume of air that is required to satisfy the space loadis delivered providing significant savings in energy.Typically the system is designed to provide supply air ata constant temperature through the control ofdischarge air temperature. VAV terminals in the spacemodulate open or closed as the load varies increasingor reducing the airflow to satisfy the demand.Temperature reset based on return air temperature isalso available.

DEHUMIDIFICATION

Indoor air quality is a major concern in the design andoperation of today’s buildings. Humidity levels, if notproperly controlled, can play a major role in thedevelopment of fungal growth which is a major causeof the problem. Controlling the space temperaturealone will not assure proper humidity control. To bringthe humidity to an acceptable level requires cooling theair to a relatively low temperature, which can result inuncomfortable conditions within the space. The air,after dehumidification, needs to be reheated to avoidthis problem. Typically electric heat has been applied todo this but is probably the most expensive optionadding significantly to operating costs. An alternativewould be to use hot water if it is available. Again thisrepresents an additional operating cost. Addition hotwater piping will be needed, increasing initial costs.MB units offer a factory installed hot gas reheat optionthat uses the hot refrigerant gas to reheat the air. All ofthe heat of rejection is not used to reheat the air sothere is a net cooling effect but not enough to createuncomfortable conditions within the occupied space.Hot gas reheat operation is controlled through spacehumidity levels and only operates when needed.
