Selection Procedure

Step 1 Determine the actual heating and cooling loads at the

desired dry bulb and wet bulb conditions.

Step 2 Obtain the following de sign parameters: Entering water

temperature, water ﬂ ow rate in GPM, air ﬂ ow in CFM,

water ﬂ ow pressure drop and design wet and dry bulb

temperatures. Air ﬂ ow CFM should be between 300 and

450 CFM per ton. Unit water pressure drop should be

kept as close as possible to each other to make water

balancing easier. Go to the ap pro pri ate tables and ﬁ nd

the proper indicated water ﬂ ow and water tem per a ture.

Step 3 Select a unit based on total and sensible cooling

conditions. Select a unit which is closest to, but no

larger than, the actual cooling load.

Step 4 Enter tables at the design water ﬂ ow and water

temperature. Read the total and sensible cooling

capacities (Note: interpolation is per mis si ble,

ex trap o la tion is not).

Step 5 Read the heating capacity. If it exceeds the design

criteria it is acceptable. It is quite normal for Water-

Source Heat Pumps to be selected on cooling capacity

only since the heating output is usually greater than the

cooling capacity.

Step 6 Determine the correction factors associated with the

variable factors of dry bulb and wet bulb (page 14).

Corrected Total Cooling = tabulated total cooling x wet

bulb correction.

Corrected Sensible Cooling = tabulated sensible cooling

x wet/dry bulb correction.

Step 7 Compare the corrected capacities to the load

re quire ments. Normally if the capacities are within 10%

of the loads, the equipment is ac cept able. It is better

to undersize than oversize, as undersizing improves

humidity control, reduces sound levels and extends the

life of the equip ment.

Step 8 When completed, calculate water temperature rise

and assess the selection. If the units selected are not

within 10% of the load cal cu la tions, then review what

effect chang ing the GPM, water temperature and/or air

ﬂ ow and air tem per a ture would have on the corrected

capacities. If the desired capacity cannot be achieved,

select the next larger or smaller unit and repeat the

procedure. Remember, when in doubt, undersize slightly

for best performance.

Example Equipment Selection For Cool ing

Step 1 Load Determination:

Assume we have determined that the appropriate cooling load

at the desired dry bulb 80°F and wet bulb 65°F con di tions is as

follows:

Total Cooling ..........................................11,500 BTUH

Sensible Cooling ........................................ 9,000 BTUH

Entering Air Temp ...... 80°F Dry Bulb / 65°F Wet Bulb

Step 2 Design Conditions:

Similarly, we have also obtained the following design pa ram e-

ters:

Entering Water Temp ........................................... 90°F

Water Flow (Based upon 12°F rise in temp.) 2.3 GPM

Air Flow ........................................................350 CFM

Step 3, 4 & 5 HP Selection:

After making our preliminary selection (CCE12), we enter the

tables at design water ﬂ ow and water tem per a ture and read

Total Cooling, Sens. Cooling and Heat of Rej. ca pac i ties:

Total Cooling ...........................................12,000 BTUH

Sensible Cooling ........................................ 8,800 BTUH

Heat of Rejection ..................................... 15,000 BTUH

Step 6 & 7 Entering Air and Airﬂ ow Corrections:

Next, we determine our correction factors.

Table Ent Air Air Flow Cor rect ed

Corrected Total Cooling = 12,000 x 0.964 x 1.000 = 11,568

Corrected Sens Cooling = 8,800 x 1.085 x 1.000 = 9,548

Corrected Heat of Reject = 15,800 x 0.967 x 1.000 = 15,279

Step 8 Water Temperature Rise Calculation & As sess ment:

Actual

Temperature Rise 13.2°F

When we compare the Corrected Total Cooling and Corrected

Sensible Cooling ﬁ gures with our load re quire ments stated

in Step 1, we discover that our selection is within +/- 10%

of our sensible load requirement. Fur ther more, we see that

our Cor rect ed Total Cooling ﬁ gure is slightly undersized as

recommended, when compared to the actual in di cat ed load.
