FEATURES/BENEFITS (cont)

Thru-the-Bottom Service Connection Capability

standard with the rooftop unit to allow power and control wiring to be routed through the unit’s basepan, thereby minimizing roof penetrations (to prevent water leaks). Both power and control connections are made on the same side of the unit to simplify installation.

The Non-Corrosive, Sloped, Condensate Drain Pan

standard and in conformance with ASHRAE (American Society of Heating, Refrigeration, and Air Conditioning Engineers) Standard 62 to meet many Indoor Air Quality (IAQ) specifications. The condensate drain pan offers both bottom and end drain capability to minimize roof penetrations. The bottom drain can be used in conjunction with thru-the-bottom connections. An external trap must be field supplied.

Standard 2-in. Throwaway Filters

are easily accessed through an easily removable filter access panel located directly above the air intake hood; no tools are required to change the filters.

All Units are Designed with a Single Continuous Top Piece

to eliminate leaking at the seams or gasketing, which tends to deteriorate over time and shift during rigging procedures.

Belt-Driven Evaporator-Fan Motors

allow maximum on-site

flexibility without changing motors or drives.

Low-Voltage Wiring Connections

are easily made due to the large terminal board which is conveniently located for quick, simple access.

QUIET, EFFICIENT OPERATION AND DEPENDABLE PERFORMANCE

All Units are Equipped With Scroll Compressors

fully hermetic with internal vibration isolators for extremely quiet operation. The scroll compressors are quieter and more reliable than reciprocating designs. Compressors are mounted on an independent plate for additional sound integrity and structural support. Efficient condenser fan and motor design permits operation at low sound levels.

Totally Enclosed Condenser-Fan Motors

and permanently

lubricated bearings provide additional dependability.

All Coils Use State-of-the-Art Internally Enhanced Copper Tubing —

Coils are thoroughly tested with helium particles as well as pressure tested at the factory. Condenser coils have louvered, aluminum lanced fins to provide maximum heat transfer for optimum efficiency and easy cleaning.

Exclusive Dimpled Heat Exchangers

optimize heat transfer for improved efficiency. The tubular design permits hot gases to make multiple passes across the path of the supply air. In addition, dimpled heat exchanger tubes act as baffles, forcing the hot gases to stay in close contact with the cell walls to maximize heat transfer and efficiency.

The California Air Quality Management NOx

40 nanograms/joule or less is met with Low kit NOx models in 036-060 sizes.

The Induced Draft Combustion System

unsightly appearance of flue stacks, and diminishes the effects of winds on heating operation. The inducer fan draws hot combustion gas through the heat exchanger at the optimum rate for the most effective heat transfer. The induced draft (negative pressure) also prevents contaminants from entering the supply air if a leak in the heat exchanger occurs.

The Direct Spark Ignition System

saves operating expense when compared to old-style pilot ignition systems. No crossover tube is required, therefore no sooting or pilot fouling problems can occur.

Refrigerant Circuit Protection

assures dependability. All units

1) loss-of-charge/low-pressure protection switch which allows

operation at lower ambient conditions while protecting against low-charge operation

2) freeze-protection thermostat, which protects against evapo-

rator coil frost build-up

3) high-pressure switch, which protects against above normal

operating pressure

4) filter driers, which trap moisture and debris in the refrigera-

tion system.

5) Bryant’s exclusive fixed orifice metering device, which pre-

cisely controls refrigerant flow, preventing slugging and floodback, while maintaining optimum unit performance by metering the circuits individually.

/2 to 121/2 ton

Two Independent Compressor Circuits

(all 7 units) provide pinpoint comfort control, improved efficiency, and back-up capability.

The Standard Control System

is readily adaptable to all con-

ventional thermostats.

Integrated Gas Unit Controller (IGC) —

All ignition components are contained in the compact Integrated Gas Controller (IGC) that is easily accessible for service. The IGC provides built in diagnostic capabilities. An LED simplifies troubleshooting by providing visual fault notification and system status information. The IGC board provides exclusive anti-cycle protection for its gas heat operation. The IGC also contains burner control logic for dependable heating operation. The LED is visible without removing the unit control box access panel. The 581B units maximize heating efficiency through the IGC’s control of evapo- rator fan ON/OFF delays. The IGC helps make 581B units reliable for many years.

Patented Cycle-LOC™ Protection System

provides protection against compressor cycling by monitoring compressor current draw. When lack of compressor current exists, the CycleLOC circuit board locks out the compressors. The Cycle-LOC board may be manually reset by simply switching thermostat to OFF, and then back to the Cooling or AUTO modes. No manipulation of the unit disconnect switch is needed.

SELECTION PROCEDURE (With 581B048 Example)

I DETERMINE COOLING AND HEATING REQUIRE-

MENTS AT DESIGN CONDITIONS.

Given:

Required Cooling Capacity (TC) . . . . . . . . . . 44,600 Btuh

Sensible Heat Capacity (SHC). . . . . . . . . . . . 32,000 Btuh

Required Heating Capacity . . . . . . . . . . . . . . 85,000 Btuh

Condenser Entering-Air Temperature . . . . . . . . . . . . 95 F

Evaporator Entering-Air Temperature . . . . . . . . .82 F edb,

67 F ewb

Evaporator Air Quantity . . . . . . . . . . . . . . . . . . . .1600 cfm

External Static Pressure (ESP) . . . . . . . . . . . . 0.75 in. wg

Electrical Characteristics (V-Ph-Hz). . . . . . . . . . . 230-1-60

II SELECT UNIT BASED ON REQUIRED COOLING

CAPACITY.

Enter the Cooling Capacities table (page 18) at condenser entering temperature of 95 F, evaporator-air entering at 1600 cfm and 80 F db and 67 F wb. The 581B--048115 unit will provide cooling capacity of 48,900 Btuh and a sensible heat capacity of 34,700 Btuh. For evaporator-air temperature other than 80 F edb, calculate sensible heat capacity correction, as required, using the formula found in Note 3 following the Cooling Capacities tables.

For this example: Correction factor = 1.10 x (1 – .21) x (82 – 80) = 1.738 Multiply the correction factor of 1.738 by 1600 cfm (a total

of 2781). From the Gross Cooling Capacities tables find that the sensible heat capacity at 80 F is 34.7 MBtuh (equivalent to 34,700 Btuh). Add 34,700 and 2781 to get the corrected sensible heat capacity of 37,481.

Unit ratings are gross capacities and do not

NOTE:

include the effect of evaporator-fan motor heat. To calculate net capacities, see Step V.

III SELECT HEATING CAPACITY OF UNIT TO PROVIDE

DESIGN CONDITION REQUIREMENTS.

In the Heating Capacities and Efficiencies table (page 5) note that unit 581B--048115 will provide output capacity of 92,000 Btuh, which is adequate for the given application.

IV DETERMINE FAN SPEED AND POWER REQUIRE-

MENTS AT DESIGN CONDITIONS.

Before entering the Fan Performance tables, calculate the total static pressure required based on unit components. From the given and the Pressure Drop tables (page 40), find:

External static pressure .75 in. wg Durablade economizer .05 in. wg

Total static pressure = .80 in. wg

Enter the Fan Performance table for 581B--048115 vertical discharge unit on page 27. At 1600 cfm, the standard motor will deliver 1.1 in. wg static pressure and 1.17 Bhp. This will adequately handle the job requirements.

Using evaporator-fan motor efficiency table and formula on page 40, determine watts.

Watts =

Watts = 116 4

V DETERMINE NET COOLING CAPACITY.

Cooling capacities are gross and do not include indoor-fan motor (IFM) heat. Determine net capacity using the following formula:

Net capacity = gross capacity – IFM heat

Net capacity = 44,928 Btuh

Net sensible capacity = 37,481 Btuh – 3972 Btuh

1.17 (746) .75

= 48,900 Btuh – 1164 Watts

(3.413

= 48,900 Btuh – 3972 Btuh

= 33,509 Btuh

gas exceeds the values listed in the table above, or if the elevation exceeds 6000 ft. Derating conditions must be 4% per thousand ft above sea level. For example, at 4000 ft, if the heating value of the gas exceeds 1000 Btu/ft elevations above 6000 ft, the same formula applies. For example, at 7000 ft, the unit will require a 28% derating of the maximum heating value per the National Fuel Gas Code.

The location of the coil in the indoor airstream enhances the latent capacity of the 581B rooftop units by up to 40%.

Many buildings suffer damage or have poor indoor-air quality due to overly humid conditions. Building humidity must be controlled for the following reasons: a.

INDOOR-AIR QUALITY —

the growth and propagation of mold and mildew in a building. The mold and mildew can spread quickly and grow in carpets and ductwork and on walls, and often causes cases of sick building syndrome. This syndrome can lead to employee absenteeism due to illness, lower worker productivity, and increased health care costs. The American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) recommends that relative humidity levels in buildings be maintained below 70%.

COMFORT LEVELS —

occupied space to become uncomfortable, because humidity interferes with the body’s natural cooling pro- cess (evaporation at the skin surface).

HUMIDITY DAMAGE —

damage, such as stained wallpaper and ceiling tiles. Humidity can also damage books and artwork, and create strong odors in carpets. In addition, humidity can contribute to unacceptable product quality in industrial processes.

IMPROPER VENTILATION —

humid geographical areas cannot be properly ventilated due to high humidity levels outdoors, resulting in poor indoor-air quality.

EQUIPMENT INEFFICIENCY —

inefficient operation of refrigerators and freezers.

INCREASED ENERGY COSTS —

humidity levels and less comfortable conditions, thermostat set points are lowered to force the HVAC (heating, ventilation, and air conditioning) equipment to run longer and work harder to lower the humidity levels. Also, in an attempt to control humidity, system designers typically oversize HVAC equipment and add reheat capability to get the desired latent capacity. This results in higher initial equipment costs, as well as increased energy expenses throughout the life of the unit.

Applications

There are many different rooftop unit applications that are susceptible to problems caused by high humidity levels. Some common applications include:

RESTAURANTS —

have many humidity-producing activities, such as dish washing and cooking.

SUPERMARKETS —

ciency in operation of refrigeration and freezer systems.

MUSEUMS AND LIBRARIES —

books and artwork.

GYMNASIUMS, LOCKER ROOMS, AND HEALTH CLUBS —

cause uncomfortable occupied space conditions.

HOT AND HUMID CLIMATES —

United States is a good example of this application. The Perfect Humidity dehumidification package becomes particularly useful when increased amounts of the hot and humid outdoor air need to be brought into the building for proper ventilation.

APPLICATION DATA (cont)

Standard Unit Refrigerant Cycle At point no. 1 in the pressure enthalpy curve, vapor leaving the

compressor at a high pressure and a high temperature enters the condenser. The condenser removes heat from the refrigerant, lowers its temperature, and changes it to a liquid. At point no. 2, the liquid leaves the condenser and enters a fixed expansion device that lowers the pressure of the refrigerant. At point no. 3, the liquid enters the evaporator coil, where the refrigerant increases in temperature and changes back to a vapor. At point no. 4, the vapor leaves the evaporator and reenters the compressor.

Refrigerant Cycle Using Perfect Humidity™ Dehumidification Package

When a subcooler coil is added to the rooftop unit, the refrigerant is affected in such a way that the unit latent capacity is increased. The refrigerant cycle follows the same path from point no. 1 to point no. 2 as the standard refrigerant cycle without a subcooler (see the pressure enthalpy curve). However, at point no. 2, the liquid refrigerant enters the subcooler coil where the temperature is lowered further. At point no. 2A, this subcooled liquid enters the TXV, which drops the pressure of the liquid. At point no. 2B, the liquid enters the fixed orifice metering device. The refrigerant leaves this device as a saturated vapor and enters the evaporator at point no. 2C. The improved refrigeration effect can now be seen between point no. 2C and point no. 3. The increase in the total refrigeration effect is the additional enthalpy gained from point no. 2C to point no. 3. However, the subcooler coil rejects this added refrigeration effect to the air downstream of the evaporator coil, thus maximizing the overall latent effect. This improved latent effect is a direct result of the addition of the Perfect Humidity subcooler coil to the refrigerant cycle.

Latent Capacity Effects Refer to the psychrometric chart to see how the sensible heat

factor decreases when the optional Perfect Humidity dehumidification package is installed. This chart contains data for the 5-ton 581B unit operation, both with and without the Perfect Humidity package, at 1750 cfm. Point no. 1 on the chart represents the return-air dry bulb (80 F) and wet bulb (67 F) conditions. Point no. 2 represents the supply-air conditions for a standard 581B rooftop unit without the Perfect Humidity dehumidification package. Point no. 3 represents the supply-air conditions for a 581B rooftop unit with the Perfect Humidity package. By connecting point no. 1 and point no. 2 on the chart and finding the intersection on the sensible heat factor scale, the sensible heat factor is 0.73. Connect point no. 1 and point no. 3, and see that the sensible heat factor is 0.58. This is a

17.5% increase in latent capacity for the given conditions. This increase in latent capacity allows the 581B rooftop units to remove more moisture from the conditioned space; thus lowering the humidity levels.

Dehumidification Effects Further evidence of dehumidification can be seen by analyzing

the pounds of water per pound of dry air found in the supply air. At point no. 2 in the psychrometric chart, there are 65 grains (0.0092 lb) of moisture per pound of dry air. At point no. 3, there are 58 grains (0.0083 lb) of moisture per pound of dry air. This is a 12.1% decrease in the amount of water in the supply air.

PERFECT HUMIDITY DEHUMIDIFICATION PACKAGE OPERATING PERFORMANCE —

midification package operation does not affect the electrical data. The electrical data remains the same either with or without the Perfect Humidity package.

The operating and shipping weights will be slightly increased with the addition of the Perfect Humidity subcooler. See the Physical Data table for added base unit weight with this option.

Refer to cooling performance data, both with and without the Perfect Humidity dehumidification package. Note the

PERFECT HUMIDITY DEHUMIDIFICATION PACKAGE FEATURES AND BENEFITS

• The Perfect Humidity dehumidification package can improve the humidity control of your rooftop equipment by up to 40%. This greatly reduces the risk of sick building syndrome by reducing biological growth in both ductwork and the rest of the building.

• The Perfect Humidity dehumidification package improves comfort levels in the building by better controlling the humidity. This improved comfort level allows building tenants to raise the cooling set point on the thermostats for accumulated energy savings.

• Better humidity control lowers the risk of humidity-induced property damage.

• The Perfect Humidity dehumidification package permits building refrigerators and freezers to operate more efficiently due to lower relative humidity levels. This is the perfect solution for supermarket applications.

• The Perfect Humidity subcooling circuit can be operated by a humidity sensor. If the sensor is used, the Perfect Humidity circuit will then only operate when needed. If the humidity levels in the occupied space are acceptable (such as in the spring and fall seasons), the Perfect Humidity circuit will not operate. The rooftop unit is then able to operate to its full sensible potential, which provides more efficient performance and energy savings.

• At lower outdoor temperatures, rooftop units with dehumidification devices are subject to low suction pressure conditions. The Perfect Humidity dehumidification package contains a low-pressure switch that deactivates the Perfect Humidity dehumidification package under low suction pressure conditions without deactivating the compressors.

• Improved humidity control allows increased outdoor-air ventilation in hot and humid geographical areas. Humidity control also helps to improve the indoor-air quality of the building.

• The Perfect Humidity dehumidification package is factory installed. There are no additional field installation costs. There is also no need to purchase a roof curb from another manufacturer, as standard Bryant roof curbs will accommodate the 581B rooftop units which have the Perfect Humidity dehumidification package option installed.

• The Perfect Humidity dehumidification package is engineered and manufactured by Bryant for Bryant rooftop units. All application support, service, and warranty issues can therefore be handled through one company.

• The slightly lower sensible capacities obtained when using the Perfect Humidity dehumidification package allow the unit to operate for an extended period of time. The more the unit operates, the more air is exposed to the subcooling coil. This rooftop unit increased latent capacity results in lower relative humidity levels in the occupied space.

• It is no longer necessary to oversize equipment and add reheat devices to properly dehumidify your building. In a typical scenario, a building owner may need 39,000 Btuh of sensible capacity and 23,000 Btuh of latent capacity (62,000 total Btuh). To accomplish this without the Perfect Humidity dehumidification package, a 7

/2-ton unit with a reheat device would be necessary to attain the higher latent capacity required. This results in a large up-front expense to oversize the equipment from a standard 5-ton to a 7

/2-ton unit.

The building owner can now purchase a 5-ton unit with the Perfect Humidity dehumidification package for a small additional up-front charge, and no reheat device will be necessary to satisfy the cooling requirements. This reduces both installation costs and operating costs throughout the life of the product.

The OFM runs continuously while the unit is in cooling. When the thermostat is satisfied, C is deenergized and the compressor and OFM shut off. After a 30-second delay, the IFM shuts off. If the thermostat fan selector switch is in the ON position, the evaporator motor will run continuously.

outdoor-air temperature is above the outdoor-air temperature (OAT) setting and the room thermostat calls for cooling, the compressor contactor is energized to start the compressor and outdoor (condenser) fan motor (OFM). The indoor (evaporator) fan motor (IFM) is energized and the economizer damper moves to the minimum position. After the thermostat is satisfied, the damper moves to the fully closed position when IFM is deenergized.

When the outdoor-air temperature is below the OAT setting and the thermostat calls for Y1 and G, the economizer damper moves to the minimum position when the evaporator fan starts. The first stage of cooling is provided by the economizer. If the supply-air temperature is above 57 F, a switch on the supply-air thermostat is closed between the T2 terminal and the 24 vac terminal. This causes the damper to continue to modulate open until the supply-air temperature falls below 55 F or the damper reaches the fully open position.

When the supply-air temperature is between 55 F and 52 F, the supply-air thermostat has open switches between the T2 and 24 vac terminals and between the T1 and 24 vac terminals. This causes the economizer damper to remain in an intermediate open position.

If the supply-air temperature falls below 52 F, a switch on the supply-air thermostat is closed between the T1 terminal and the 24 vac terminal. This causes the damper to modulate closed until the supply-air temperature rises above 55 F or the damper reaches the minimum position.

When the supply-air temperature is between 55 F and 57 F, the supply-air thermostat has open switches between the T2 and 24 vac terminals. This causes the economizer damper to remain in an intermediate open position.

If the outdoor air alone cannot satisfy the cooling requirements of the conditioned space, economizer cooling is integrated with mechanical cooling, providing second stage cooling. The compressor and condenser fan will be energized and the position of the economizer damper will be determined by the supply-air temperature.

When the second stage of cooling is satisfied, the compressor and condenser-fan motor will be deenergized. The damper position will be determined by the supply-air temperature.

OPERATING SEQUENCE FOR 581B036-150 SIZE UNITS Units With Perfect Humidity™ Dehumidification Package —

When thermostat calls for cooling, terminals G and Y1 is energized. The indoor (evaporator) fan motor (IFM), compressor (C), and outdoor (condenser) fan motor (OFM) start. The OFM runs continuously while the unit is in cooling. As shipped from the factory, Perfect Humidity dehumidification circuit is always energized. If Perfect Humidity circuit modulation is desired, a fieldinstalled, wall-mounted LC Thermidistat or humidistat are required.

If the Perfect Humidity humidistat is installed and calls for the Perfect Humidity subcooler coil to operate, the humidistat internal switch closes. This energizes and closes the liquid line solenoid valve coil (LLSV) of the Perfect Humidity circuit, forcing the hot liquid refrigerant of the liquid line to enter the subcooler coil. As the hot liquid passes through the subcooler coil, it is exposed to the cold supply airflow coming off from the evaporator coil and the liquid is further cooled to a temperature approaching the evaporator coil leaving-air temperature. The state of the refrigerant leaving the subcooler coil is a highly subcooled liquid refrigerant. The liquid then enters a thermostatic expansion valve (TXV) where the liquid is dropped to a lower pressure. The TXV does not have a pressure drop great enough to change the liquid to a 2-phase fluid. The TXV can throttle the pressure drop of the liquid refrigerant and maintain proper conditions at the compressor suction valve over a wide range of operating conditions. The liquid then enters a second fixed restrictor expansion device for a second pressure drop to a 2-phase fluid. The liquid proceeds to the evaporator coil at a temperature lower than normal cooling operation. This lower temperature is what increases the latent capacity of the rooftop. The 2-phase refrigerant passes through the evaporator and is changed into a vapor. The air passing over the evaporator coil will become colder than during normal operation as a result of the colder refrigerant temperatures. However, as it passes over the subcooler coil, the air will be warmed slightly.

As the refrigerant leaves the evaporator, the refrigerant passes a low-pressure switch in the suction line. This low-pressure switch will deactivate the Perfect Humidity package when the suction pressure reaches 60 psig. The low-pressure switch is an added safety device to protect against evaporator coil freeze-up. The low-pressure switch will only deactivate and open the liquid line solenoid valve in the Perfect Humidity circuit. The compressors will continue to run as long as there is a call for cooling, regardless of the position of the low-pressure switch. The solenoid valve and the Perfect Humidity package will be re-activated only when the call for cooling has been satisfied, the low-pressure switch has closed, and a new call for cooling exists. The crankcase heaters on the scroll compressor provide additional protection for the compressor due to the additional refrigerant charge in the subcooler.

When the humidistat is satisfied, the humidistat internal switch opens cutting power to and opening the LLSV. The refrigerant is routed back through the evaporator and the subcooler coil is removed from the refrigerant loop.

When the thermostat is satisfied, C1 is deenergized and the compressor and OFM shut off. After a 30-second delay, the IFM shuts off. If the thermostat fan selector switch is in the ON position, the IFM will run continuously.
