Features/Benefits

The 42BHC, BVC belt drive fan coil units provide yearround comfort air conditioning with central station operating economy.

A variety of coil options reduces first cost

Four, 6 or 8-row cooling coils combine needed capacities with the most efficient heat transfer surface. For 4-pipe systems, select either of two split-coil options. Coils consist of aluminum fins securely bonded to OD seamless copper tubes. Each fin’s aluminum collar ensures accurate control of the fin spacing, while completely covering the tubes to lengthen coil life. All coils also feature manual air vents, with automatic air vent available as an option.

42BVC UNIT

Fan wheels are designed to provide low operating costs

The forward-curved, centrifugal, double-inlet fans are statically and dynamically balanced at the factory to minimize transmission of vibration to the building structure.

The belt-driven motor (single or three phase) has a variable-pitch pulley which adjusts at the jobsite to accommodate limited ranges of air quantities and pressures.

All motors (single and three phase) are UL listed, factory wired, single speed with thermal overload protection and are continuous duty rated. Motors are supplied with permanently lubricated bearings, class-B insulation and are open drip-proof. The motor mount has an adjustable platform for easy belt adjustment. The motor and its mounting are independently isolated from the cabinet and the blower. An adjustable pitch pulley allows cfm balancing to meet system requirements. Motor drive packages are provided with keyed pulleys.

Complete factory assembly minimizes on-the-jobsite costs and problems

Compact, lightweight units are designed for easy mounting. Knockouts designed to accept

/8-in. threaded rods are

provided on the top and bottom of each corner of the unit One-in. duct collars on discharge and on return are furnished standard. These integral duct collars cut installation time and labor expense.

Durable construction means easy-to-maintain units

The 42BHC,BVC fan coils casings are fabricated from heavy-gage galvanized G90 steel, reinforced for maximum rigidity and structural strength. Removable side panels with tool-less camlock fasteners allow easy access for servicing interior components.

One-inch matte surface, fiberglass thermal/acoustical insulation lines the fan coil cabinets to prevent sweating and to muffle sound transmission.

The stainless steel, double-sloped condensate drain pan extends under full coil surface to cut maintenance costs.

Slide-in return-duct collar filter makes it possible to remove and replace the filter without disturbing return air ductwork.

PIPING COMPONENTS

SYMBOL/SKETCH DESCRIPTION

MANUAL AIR VENT: Threaded brass needle valve

with screwdriver slot for adjustment. Application — Body brazed into high point of heat-

ing and cooling coils for bleeding air from coil. Standard item on all hydronic coils (not used on steam or DX coils). Should not be used in lieu of main system air vents.

AUTOMATIC AIR VENT: Nickel plated brass valve, fiber-disc type, with positive shut-off ballcheck and quick vent feature via knurled vent screw.

Application — Optional replacement for manual air vent. Automatically passes minute quantities of air through the fiber discs which expand upon contact with water, completely sealing the valve. As air accumulates, the fiber discs dry and shrink, repeating the cycle. Not recommended for removing large quantities of air encountered during initial start-up or subsequent draining and refilling. Should not be used in lieu of main system air vents.

SWAGE: Copper tube end expanded to accept a copper tube of the same size for factory or field brazing.

Application — Used where possible for all tubing joints for best joint integrity.

CIRCUIT SETTER: Variable water flow balancing valve with manual adjustment knob, pointer, percent-open scale, memory stop and integral pressure read-out ports.

Application — Used for close tolerance water flow balancing. Positive shut-off ball valve feature allows usage as combination balancing and shut-off valve.

Balance by temperature differential or coil pressure drop (check specifications for service fittings required if balancing by pressure drop). May be used in 3-way valve bypass line to permit equal flow balancing.

STRAINER: Y-type body with 50 mesh stainless steel screen.

Application — Used for removal of small particles from system water during normal system operation. Should not be used in lieu of main system strainers. Strainer screen may have to be removed during initial high pressure system flushing during start-up. Screen should be removed and cleaned per normal maintenance schedule (provisions for strainer blow-down not provided).

BALL VALVE: Manual balance and shut-off valve. Application — Used for unit isolation and water flow

balancing. Without memory stop feature water balance point must be marked by installer (if necessary). Check specifications for service fittings required when used for water balancing.

2-WAY MOTORIZED VALVE: Electric

2-position flow control valve (open/closed). Normally closed body with manual override lever. Installed in supply line to unit.

Application — All standard control and valve packages are based upon normally closed valves (valve electrically powered open and closed by spring return when electric power removed). Manual override lever allows valve to be placed in the open position for secondary (unit) flushing, constant water flow prior to start-up, etc. Manual override is automatically disengaged when valve is electrically activated. Consult factory for normally open

valve applications.

3-WAY MOTORIZED VALVE: Electric

2-position flow control valve (closed to coil/ open to bypass or open to coil/closed to bypass). Normally closed with manual override lever. Installed in supply line to unit.

Application — Same comments as 2-way motorized valve except with manual override lever engaged the valve is open to both ports and water flow will take the path of least resistance through the valve package (not necessarily 100% through the coil).

Selection procedure

This selection procedure provides a guide to determine unit performance of the 42BHC, BVC units. Capacity tables (in Performance Data) are based on nominal cfm. Correction factors are provided for other operating conditions as explained in the following selection example.

For applications outside the range provided in this

catalog, please consult the factory.

FORMULAS:

TC = TCb x Ct x Et SC = SCb x Cs x Es

Where: Cs = Sensible Airflow Correction Factor

Ct = Total Airflow Correction Factor Es = Sensible Elevation Correction Factor Et = Total Elevation Correction Factor SC = Sensible Capacity SCb = Base Sensible Capacity from Base Cooling Capaci-

ties by gpm charts TC = Total Capacity TCb = Base Total Capacity from Base Cooling Capacities by gpm charts

EXAMPLE:

I Rate unit performance.

To rate the performance at sea level for a 42BHC16 unit with a four-row coil at 80 F/67 F EAT, 45 F EWT, 7 gpm water flow, and 1500 cfm:

a) Enter the Base Cooling Capacities by Gpm, 4-Row

Capacity Units table at 80 F/67 F EAT and 45 F EWT.

b) Locate the appropriate row for unit size 16 and

7 gpm. Record the tabulated base performance. TCb = 42.0 MBtuh

SCb = 34.2 MBtuh ∆T = 12.0 F

c) Divide CFM Actual by CFM Nominal to determine

Cfm Ratio. Cfm Ratio = 1500/1600 =.9375

II Select CFM correction factors.

Select the Cfm correction factors, Ct and Cs, from the Airflow Correction Factors table. (Interpolation may be required.)

Ct = .9625 Cs = .96 Select the elevation correction factors, Et and Es, from

the Elevation Correction Factors table. (No correction necessary in this example, unit is at sea level.)

Et = 1.00 Es = 1.00

III Calculate actual performance.

TC = TCb x Ct x Et = 42.0 x .9625 x 1.00 = 40.42 MBtuh

SC = SCb x Cs x Es = 34.2 x .96 x 1.00 = 32.83 MBtuh a) Calculate water pressure drop (or refer to the Water

Pressure Drop for Cv Factor and Water Flow Rate table on page 33). From the Cv Factor by Coil and Unit Size table on page 32, find the Cv value for unit size 16 with four rows.

Cv = 7.2 P = [GPM/(0.658 x Cv)]2 = [7.0/(0.658 x 7.2)]2 = 2.18 feet of H

b) For selections other than those listed here, please

contact the factory.

IV Determine motor.

To determine motor and drive selection requirements and obtain the cfm for a specific application, the total static pressure (TSP) for that application must be determined.

The TSP is the sum of the internal static pressure (ISP) and the external static pressure (ESP) measured in inches of water column. Internal static pressure is the sum of the static resistance of the unit’s components — the cabinet, coil and filter. The ESP is the static resistance of the unit’s external components, including, but not limited to, ductwork, grilles and additional filtration. For non-ducted applications, the ESP is 0 in. wg.

After the TSP has been calculated (see the following example), use the motor horsepower table on pages 30 and 31 to determine actual horsepower (hp) for the belt drive unit. Horsepower offerings are limited to

/2, 3/4, 1, 11/2, 2, 3 and 5.

The standard selection is the nearest offering above the actual hp shown in the table.

Using the TSP of the table, match the unit size with the cfm row to determine the correct motor for the specific application. Drive sheaves and the required belt assembly will be provided to meet specific design requirements. Drive sheaves are set at the factory.

Calculate the hp and drive selection required to deliver 1500 cfm on a 42BHC16 unit equipped with a 4-row hydronic cooling coil and a 2-in. pleated filter in a ducted application at .38 in. ESP, including duct and grille losses.

Using the Component Static Resistance table on page 32, the ISP is calculated as follows:

Cabinet .09-in. wg 4-row Wet Coil .30-in. wg 2-in. Pleated Filter .12-in. wg ISP .51-in. wg ESP .38-in. wg TSP .89-in. wg

Hydronic coil pressure drop — All of the factory’s hydronic coils have a coefficient of velocity (Cv) resistance factor assigned to assist in a more accurate determination of water pressure drop (see Cv Factor by Coil and Unit Size table below).

Calculating pressure drop:

The Cv factor is equal to the flow rate of water in gpm through a piping component when the pressure drop through the component is 1.0 pounds per square inch (psi), or 2.31 ft wg.

∆P (ft wg) = ∆P (psi) x 2.31

Use the Cv factor from the Cv Factor by Coil and Unit Size table to determine the water coil pressure drop.

Coil pressure drop (ft wg):

∆P = (GPM

/Cv

) x 2.31

∆P = [GPM/(0.658 x Cv)]

Refer to the Water Pressure Drop for Cv Factor and

Water Flow Rate table. See example on page 22.
