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 design parameters: Entering water temperature, water flow rate in GPM, air flow in
CFM, water flow pressure drop and design wet and dry bulb temperatures. Air flow 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 appropriate tables and find the proper indicated water flow and water temperature.
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 flow and water temperature. Read the total and sensible cooling capacities
(Note: interpolation is permissible, extrapolation 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.
Step 7
Step 8
Corrected Total Cooling = tabulated total cooling x wet bulb correction.
Corrected Sensible Cooling = tabulated sensible cooling x wet/dry bulb correction.
Compare the corrected capacities to the load requirements. Normally if the capacities are within 10% of the loads, the equipment is acceptable. It is better to undersize than oversize, as undersizing improves humidity control, reduces sound levels and extends the life of the equipment.
When completed, calculate water temperature rise and assess the selection. If the units selected are not within 10% of the load calculations, then review what effect changing the GPM, water temperature and/or air flow and air temperature 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 Cooling
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 conditions is as follows:
Total Cooling...........................................................10,200 BTUH
Sensible Cooling.......................................................8,350 BTUH
Entering Air Temp.......................80°F Dry Bulb/65°F Wet Bulb
Step 2 Design Conditions:
Similarly, we have also obtained the following design parameters:
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 (HRC12), we enter the tables at design water flow and water temperature and read Total
Cooling, Sens. Cooling and Heat of Rej. capacities:
Total Cooling...........................................................10,800 BTUH
Sensible Cooling.......................................................9,200 BTUH
Heat of Rejection....................................................13,900 BTUH
Step 6 & 7 Entering Air and Airflow Corrections:
Next, we determine our correction factors.
Table Ent Air Air Flow Corrected
Corrected Total Cooling = 10,800 x 0.976 x 0.954 =10,056
Corrected Sens Cooling = 9,200 x 1.071 x 0.927 = 9,134
Corrected Heat of Reject = 13,900 x 0.979 x 0.958 = 13,037
Step 8 Water Temperature Rise Calculation & Assessment:
Actual Temperature Rise.....................................................11.3°F
When we compare the Corrected Total Cooling and Corrected
Sensible Cooling figures with our load requirements stated in Step
1, we discover that our selection is within +/- 10% of our sensible load requirement. Furthermore, we see that our Corrected Total
Cooling figure is slightly undersized as recommended, when compared to the actual indicated load.

In this example, a higher flow rate will be required for EWTs at or below 50°F without antifreeze. At 2 gpm/ton, the calculation above results in a TD of 7.5. LWT = 50 - 7.5 = 42.5°F, which is above 42°F EWT, and is acceptable for this application.

Operation Not Recommended
Interpolation is permissible; extrapolation is not.
All entering air conditions are 80°F DB and 67°F WB in cooling, and 70°F DB in heating. ARI/ISO certified conditions are 80.6°F DB and
66.2°F WB in cooling and 68°F DB in heating.
Table does not reflect fan or pump power corrections for ARI/ISO conditions.
All performance is based upon the lower voltage of dual voltage rated units.
Operation below 40°F EWT is based upon a 15% antifreeze solution.
Operation below 60°F EWT requires optional insulated water/refrigerant circuit (standard on residential models).
See performance correction tables for operating conditions other than those listed above.
See Performance Data Selection Notes for operation in shaded areas.

Interpolation is permissible; extrapolation is not.
All entering air conditions are 80°F DB and 67°F WB in cooling, and 70°F DB in heating.
AHRI/ISO certified conditions are 80.6°F DB and 66.2°F WB in cooling and 68°F DB in heating.
Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
All performance is based upon the lower voltage of dual voltage rated units.
Performance stated is at the rated power supply; performance may vary as the power supply varies from the rated.
Operation below 40°F EWT is based upon a 15% methanol antifreeze solution.
Operation below 60°F EWT requires optional insulated water/refrigerant circuit.
See performance correction tables for operating conditions other than those listed above.
See Performance Data Selection Notes for operation in the shaded areas.

Option: Enhanced solid state control system (DXM)
This control system features two stage control of cooling and two stage control of heating modes for exacting temperature and dehumidification purposes.
