4 Unit Features THE TRANQUILITY 20 SINGLE-STAGE (TS) SERIES The award wng Tranquility Series raises the bar for water-source heat pump efficiencies, features and application flexibility. Not only does the Tranquility 20 far exceed ASHRAE 90.1 efficiencies, but it also uses EarthPure (HFC-410A) zero ozone depletion refrigerant, makg it an extremely environmentally-friendly option. Tranquility 20 is eligible for additional LEED (Leadership Energy and Environmental Design) pots because of the green technology design. Available sizes 1/2 tons (1.76 kw) through 6 tons (21.1 kw) with multiple cabet options (vertical upflow, vertical downflow and horizontal) the Tranquility 20 offers a wide range of units for most any stallation. The Tranquility 20 has an extended range refrigerant circuit, capable of ground loop (geothermal) applications as well as water loop (boilertower) applications. Standard features are many. Copeland scroll compressors, microprocessor controls, galvanized steel cabet, polyester powder coat pat, staless steel dra pan and foil-backed air handler sulation are just some of the features of the Tranquility 20 Series. ClimateMaster s exclusive double isolation compressor mountg system makes the Tranquility 20 the quietest unit on the market. Compressors are mounted on specially engeered sound tested EPDM grommets to a heavy gauge mountg plate, which is then isolated from the cabet base with rubber grommets for maximized vibration/sound attenuation. The unique low profile slanted control box makes stallg and matag the unit easier than any other water-source heat pump currently production. UNIT FEATURES Sizes 006 (1/2 ton, 1.76 kw) through 070 (6 tons, 21.1 kw) EarthPure (HFC-410A) refrigerant Exceeds ASHRAE 90.1 efficiencies Galvanized steel construction with attractive black mat polyester powder coat pat and silver accents Staless steel dra pan Foil-backed sulation air handler section Unique double isolation compressor mountg with vibration isolation for quiet operation Insulated divider and separate compressor/air handler compartments Copeland scroll compressors TXV meterg device Extended range (20 to 120 F, -6.7 to 48.9 C) operation Microprocessor controls standard (optional DXM and/or DDC controls) LonWorks, BACnet, Modbus and Johnson N2 compatibility options for DDC controls Field convertible discharge air arrangement for horizontal units High static blowers available ECM variable speed fan motor available Low profile slanted control box for easy access Flush securely-mounted corner post water connections (no backup wrench required) Unit Performance Sentel performance monitorg system Eight Safeties Standard Wide variety of options cludg ClimaDry modulatg reheat, coated air coils and ternal pumps Options such as ECM variable speed fan motor, coated air coil, DDC controls, ternal pump and high efficiency MERV 11 two-ch (51mm) air filters allow customized design solutions. Optional high static fan motors help overcome some of the challenges associated with ductwork for retrofit stallations. The Tranquility 20 (TS) Series Water-Source Heat Pumps are designed to meet the challenges of today s HVAC demands with one of the most novative products available on the market. LC377-4

EWT = enterg water temperature GPM = water fl ow U.S. gallons/mute HE = total heat of extraction, BTUH HC = air heatg capacity, BTUH HR = total heat of rejection, BTUH HWC = hot water generator (desuperheater) capacity, Mbtuh FPT = female pipe thread KW = total power unit put, kilowatts LAT = leavg air temperature, F LC = latent coolg capacity, BTUH LWT = leavg water temperature, F MBTUH = 1000 BTU per hour S/T = sensible to total coolg ratio SC = sensible coolg capacity, BTUH TC = total coolg capacity, BTUH WB = wet bulb temperature F WPD = waterside pressure drop (psi & ft. of hd.)

6 Selection Procedure Step 1 Determe the actual heatg and coolg loads at the desired dry bulb and wet bulb conditions. Step 2 Obta the followg de sign parameters: Enterg water temperature, water flow rate GPM, air flow, water flow pressure drop and design wet and dry bulb temperatures. Air flow should be between 300 and 450 per ton. Unit water pressure drop should be kept as close as possible to each other to make water balancg easier. Go to the ap pro pri ate tables and fd the proper dicated water flow and water tem per a ture. Step 3 Select a unit based on total and sensible coolg conditions. Select a unit which is closest to, but no larger than, the actual coolg load. Step 4 Enter tables at the design water flow and water temperature. Read the total and sensible coolg capacities (Note: terpolation is per mis si ble, ex trap o la tion is not). Step 5 Read the heatg capacity. If it exceeds the design criteria it is acceptable. It is quite normal for water source heat pumps to be selected on coolg capacity only sce the heatg output is usually greater than the coolg capacity. Step 6 Determe the correction factors associated with the variable factors of dry bulb and wet bulb. Corrected Total Coolg = tabulated total coolg x wet bulb correction. Corrected Sensible Coolg = tabulated sensible coolg x wet/dry bulb correction. Step 7 Compare the corrected capacities to the load re quire ments. Normally if the capacities are with 10% of the loads, the equipment is ac cept able. It is better to undersize than oversize, as undersizg 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 with 10% of the load cal cu la tions, then review what effect chang g the GPM, water temperature and/or air flow 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 doubt, undersize slightly for best performance. Example Equipment Selection For Cool g Step 1 Load Determation: Assume we have determed that the appropriate coolg load at the desired dry bulb 80 F and wet bulb 65 F con di tions is as follows: Total Coolg...23,000 BTUH Sensible Coolg...17,000 BTUH Enterg Air Temp...80 F Dry Bulb / 65 F Wet Bulb Step 2 Design Conditions: Similarly, we have also obtaed the followg design pa ram e ters: Enterg Water Temp...90 F Water Flow (Based upon 10 F rise temp.) GPM Air Flow Step 3, 4 & 5 HP Selection: After makg our prelimary selection (TS024), we enter the tables at design water flow and water tem per a ture and read Total Coolg, Sens. Coolg and Heat of Rej. ca pac i ties: Total Coolg...25,200 BTUH Sensible Coolg...18,400 BTUH Heat of Rejection...31,100 BTUH Step 6 & 7 Enterg Air and Airflow Corrections: Next, we determe our correction factors. Table Ent Air Air Flow Cor rect ed Corrected Total Coolg = 25,200 x x = 23,782 Corrected Sens Coolg = 18,400 x x = 17,368 Corrected Heat of Reject = 31,100 x x = 29,519 Step 8 Water Temperature Rise Calculation & As sess ment: Actual Temperature Rise F When we compare the Corrected Total Coolg and Corrected Sensible Coolg figures with our load re quire ments stated Step 1, we discover that our selection is with +10% of our sensible load requirement. Fur ther more, we see that our Cor rect ed Total Coolg figure is with 1,000 Btuh of the actual di cat ed load. LC377-6

9 Performance Data Selection Notes For operation the shaded area when water is used lieu of an antifreeze solution, the LWT (Leavg Water Temperature) must be calculated. Flow must be mataed to a level such that the LWT is mataed above 40 F [4.4 C] when the JW3 jumper is not clipped (see example below). Otherwise, appropriate levels of a proper antifreeze solution should be used systems with leavg water temperatures of 40ºF [4.4 C] or below and the JW3 jumper should be clipped. This is due to the potential of the refrigerant temperature beg as low as 32 F [0 C] with 40 F [4.4 C] LWT, which may lead to a nuisance cutout due to the activation of the Low Temperature Protection. JW3 should never be clipped for standard range equipment or systems without antifreeze. Example: At 50 F EWT (Enterg Water Temperature) and 1.5 gpm/ton, a 3 ton unit has a HE of 22,500 Btuh. To calculate LWT, rearrange the formula for HE as follows: HE = TD x GPM x 500, where HE = Heat of Extraction (Btuh); TD = temperature difference (EWT - LWT) and GPM = U.S. Gallons per Mute. TD = HE / (GPM x 500) Heatg - EAT 70 F ER Airflow HC kw HE LAT COP N/A N/A TD = 22,500 / (4.5 x 500) TD = 10 F LWT = EWT - TD LWT = = 40 F In this example, as long as the EWT does not fall below 50 F, the system will operate as designed. For EWTs below 50 F, higher flow rates will be required (open loop systems, for example, require at least 2 gpm/ton when EWT is below 50 F). LC377-9
