SELECTION PROCEDURE (WITH 581J*07A EXAMPLE)

Determine cooling and heating loads.

Given:

Mixed air dry bulb

F (27

Mixed air wet bulb

F (19

Ambient dry bulb

F (35

Load

73.6 MBH

SHC

Load

53.3 MBH

Vertical supply air

2100 CFM

Heating load

85.0 MBH

External static pressure

0.67 in. wg

Electrical characteristics

230--3--60

II.

Make an initial guess at cooling tons.

Refrig. tons = TC

Load

/ 12 MBH per ton

Refrig. tons = 72.0 / 12 = 6.0 tons

In this case, start by looking at the 581J**07.

III. Look up the rooftop’s TC and SHC.

Table 15 shows that, at the application’s supply air

CFM, mixed air and ambient temperatures, the

581J*A07 supplies:

TC = 73.6 MBH

SHC = 53.3 MBH

IV. Calculate the building latent heat load.

Load

= TC

Load

-- SHC

Load

= 72.0 MBH -- 54.0 MBH = 18.0 MBH

Calculate RTU latent heat capacity.

LC = TC -- SHC

LC = 73.6 MBH -- 53.3 MBH = 20.3 MBH

VI. Compare RTU capacities to loads.

Compare the rooftop’s SHC and LC to the

building’s sensible and latent heat loads.

VII. Select factory options (FIOP)

Local code requires an economizer for any unit with

TC greater than 65.0 MBH.

VIII. Calculate the total static pressure.

External static pressure

0.67 in. wg

Sum of FIOP / Accessory static

+0.13 in. wg

Total Static Pressure

0.80 in. wg

IX. Look up the indoor fan RPM & BHP.

Table 36 shows, at 2100 CFM & ESP= 0.8,

RPM = 712 & BHP = 1.17

Convert BHP (Step VIII) into fan motor heat.

Fan motor heat = 2.546* BHP/Motor Eff.

Fan motor heat = 3.7 MBH

XI. Calculate RTU heating capacity.

Building heating load

85.0 MBH

Fan motor heat

--3.7 MBH

Required heating capacity

81.3 MBH

XII. Select a gas heater.

Table 4 shows the heating capacities of the

581JEA07 = 103.0 MBH. Select the 581JEA07

XIII. Determine electrical requirements.

Table 45 shows the MCA and Breaker Size of a

581J*A07 (without convenience outlet) as:

MCA = 32.0 amps & MOCP = 50.0 amps

Min. disconnect size: FLA = 31.0 & LRA = 148.

LEGEND

BHP

— Break horsepower

FLA

— Full load amps

— Latent capacity

LRA

— Lock rotor amp

MBH

— (1,000) BTUH

MCA

— Min. circuit ampacity

MOCP — Max. over---current protection

RPM

— Revolutions per minute

RTU

— Rooftop unit

SHC

— Sensible heat capacity

— Total capacity

NOTES

1. Selection software by Bryant saves time by performing

many of the steps above. Contact your Bryant sales

representative for assistance.

2. Unit ratings are gross capacities and do not include the

effect of evaporator fan motor heat. See Step XI. for de-

termining amount of evaporator fan motor heat to sub-

tract from total and sensible capacities to obtain net

cooling and net sensible capacities.

3. Selecting a unit with a SHC slightly lower than the

SHC

Load

is often better than oversizing. Slightly lower

SHC’s will help control indoor humidity, and prevent

temperature swings.

4. Indoor fan motor efficiency is available in Table 41. Use

the decimal form in the equation, eg. 80% = .8.
