THE SMART SOLUTION FOR ENERGY EFFICIENCYTr a n q u i l i t y 2 7 Tw o - S t a g e ( T T ) S e r i e sR e v. : 0 5 / 2 2 / 0 7 DSelection ProcedureStep 1 Determine the actual heating and cooling loads at thedesired dry bulb and wet bulb conditions.Step 2 Obtain the following design parameters: Entering watertemperature, water flow rate in GPM, air flow in CFM,water flow pressure drop and design wet and dry bulbtemperatures. Air flow CFM should be between 300 and450 CFM per ton. Unit water pressure drop should bekept as close as possible to each other to make waterbalancing easier. Go to the appropriate tables and findthe proper indicated water flow and water temperature.Step 3 Select a unit based on total and sensible coolingconditions. Select a unit which is closest to, but nolarger than, the actual cooling load.Step 4 Enter tables at the design water flow and watertemperature. Read the total and sensible coolingcapacities (Note: interpolation is permissible,extrapolation is not).Step 5 Read the heating capacity. If it exceeds the designcriteria it is acceptable. It is quite normal for WaterSource Heat Pumps to be selected on cooling capacityonly since the heating output is usually greater than thecooling capacity.Step 6 Determine the correction factors associated with thevariable 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 loadrequirements. Normally if the capacities are within 10%of the loads, the equipment is acceptable. It is betterto undersize than oversize, as undersizing improveshumidity control, reduces sound levels and extends thelife of the equipment.Step 8 When completed, calculate water temperature riseand assess the selection. If the units selected are notwithin 10% of the load calculations, then review whateffect changing the GPM, water temperature and/or airflow and air temperature would have on the correctedcapacities. If the desired capacity cannot be achieved,select the next larger or smaller unit and repeat theprocedure. Remember, when in doubt, undersizeslightly for best performance.Example Equipment Selection For CoolingStep 1 Load Determination:Assume we have determined that the appropriate cooling loadat the desired dry bulb 80 F and wet bulb 65 F conditions isas follows:Total Cooling . 22,100 BTUHSensible Cooling . 16,500 BTUHEntering Air Temp. 80 F Dry Bulb / 65 F Wet BulbStep 2 Design Conditions:Similarly, we have also obtained the following design parameters:Entering Water Temp . 90 FWater Flow (Based upon 10 F rise in temp.) 6.0 GPMAir Flow . 730 CFMStep 3, 4 & 5 HP Selection:After making our preliminary selection (TTH026 - Full Load), weenter the tables at design water flow and water temperature andread Total Cooling, Sens. Cooling and Heat of Rej. capacities:Total Cooling . 24,200 BTUHSensible Cooling . 16,300 BTUHHeat of Rejection . 29,900 BTUHStep 6 & 7 Entering Air and Airflow Corrections:Next, we determine our correction factors.TableEnt Air Air Flow CorrectedCorrected Total Cooling 24,200 x 0.975 x 0.978 23,076Corrected Sens Cooling 16,300 x 1.096 x 0.926 16,543Corrected Heat of Reject 29,900 x 0.979 x 0.978 28,628Step 8 Water Temperature Rise Calculation & Assessment:Actual Temperature Rise9.5 FWhen we compare the Corrected Total Cooling and CorrectedSensible Cooling figures with our load requirements statedin Step 1, we discover that our selection is within /- 10% ofour sensible load requirement. Furthermore, we see that ourCorrected Total Cooling figure is within 1,000 Btuh the actualindicated load.w w w. c l i m a t e m a s t e r. c o mTT5
