Carrier’s versatile belted fan coil units

satisfy design requirements:

• A selection of 8 sizes covers

capacities from 600 to 4000 cfm

• Choice of motors, from 1/4to 5 hp,

eliminates oversizing

• Wide range of coil options for 2-pipe

or 4-pipe systems

• Optional DX coils with expansion

valve and distributor

• Single and three-phase electric

heat (1.0 to 40 kW)

Features/Benefits

The 42BHC, BVC belt drive

fan coil units provide year-

round 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 effi-

cient heat transfer surface. For

4-pipe systems, select either of two

split-coil options. Coils consist of alu-

minum fins securely bonded to 1/2-in.

OD seamless copper tubes. Each fin’s

aluminum collar ensures accurate con-

trol of the fin spacing, while complete-

ly covering the tubes to lengthen coil

life. All coils also feature manual air

vents, with automatic air vent available

as an option.

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 accom-

modate limited ranges of air quantities

and pressures.

All motors (single and three phase)

are UL listed, factory wired, single

speed with thermal overload protec-

tion 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 bal-

ancing 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 3/8-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 fur-

nished 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. Remov-

able side panels with tool-less camlock

fasteners allow easy access for servic-

ing 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.

TOTAL WEIGHT UNIT CORRECTION FACTOR (lb)

Corner weights on pages 12 and 13 are for 8-row water filled coils. For a different number of rows, total unit weight

can be determined by the following procedure:

• Identify the number of rows and the size of the unit.

• Determine the total weight of the unit from the Corner Weight tables.

• From the table below, identify the correction factor (for size of unit and number of rows) and subtract this from the

total weight.

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. Stan-

dard item on all hydronic coils (not used on steam

or DX coils). Should not be used in lieu of main sys-

tem 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, repeat-

ing 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.

N/A N/A 125 240

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 H2O

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 1/4, 1/3,

1/2, 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 deliv-

er 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 hy-

dronic 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 = (GPM2/Cv2 ) x 2.31

∆P = [GPM/(0.658 x Cv)]2

Refer to the Water Pressure Drop for Cv Factor and

Water Flow Rate table. See example on page 22.
