3 Unit Features TRANQUILITY CONSOLE (TRC) SERIES WITH EARTHPURE HFC-410A REFRIGERANT The Tranquility Series (TRC) console unit provides a high efficiency WSHP ductless solution for spaces where individual, quiet control of the heating and cooling system is important. TRC units are especially ideal where ceiling height and space are limited, or when preserving the integrity of an existing structure. The TRC Series exceeds ASHRAE 90.1 efficiencies, yet maintains small cabinet dimensions. Using EarthPure HFC-410A refrigerant, the Tranquility console not only protects the environment, it does so while delivering unprecedented comfort, efficiency, and reliability. Available in sizes 3/4 ton (2.64 kw) through 1-1/2 tons (5.3 kw) with numerous cabinet, water piping and control choices, the TRC Series offers a wide range of units for most any installation. The TRC has an extended range refrigerant circuit, capable of ground loop (geothermal) applications as well as water loop (boiler-tower) applications. Standard features are many. Microprocessor controls, galvanized steel cabinet, polyester powder coat paint and TXV refrigerant metering device are just some of the features of the flexible TRC series. Compressors are mounted on specially engineered soundtested EPDM grommets for quiet operation. Options such as coated air coil, DDC controls, internal pump and factoryinstalled water solenoid valves allow customized design solutions. The TRC Series console water-source heat pumps are designed to meet the challenges of today s HVAC demands with a low cost/high value ductless solution. UNIT FEATURES Sizes 09 (3/4 ton, 2.64 kw) through 18 (1-1/2 ton, 5.3 kw Environmentally-friendly EarthPure (HFC-410A) zero ozone depletion refrigerant High Efficiency Rotary compressors Exceeds ASHRAE 90.1 efficiencies Two-piece chassis/cabinet design Galvanized steel cabinet with durable Polar Ice powder coat finish and black matte finish on subbase Slope top/aluminum rigid bar supply air grille UltraQuiet Option TXV metering device Extended range (20 to 120 F, -6.7 to 48.9 C) operation Advanced digital auto change-over unit mounted controls with temperature display and high/low fan speed selection Remote-mounted controls available Microprocessor controls standard (optional DXM and/or DDC controls) LonWorks, BACnet, Modbus and Johnson N2 compatibility options for DDC controls Right or left-hand piping arrangement Front or bottom return air configuration Unit Performance Sentinel performance monitoring system Eight Safeties Standard Wide variety of options including coated air coil, flow regulator, motorized water valve, stainless steel drain pan, locking control door, disconnect switch, and internal pump.

EWT = entering water temperature GPM = water flow in U.S. gallons/minute HE = total heat of extraction, BTUH HC = air heating capacity, BTUH HR = total heat of rejection, BTUH MBTUH = 1000 BTU per hour S/T = sensible to total cooling ratio SC = sensible cooling capacity, BTUH TC = total cooling capacity, BTUH WB = wet bulb temperature ( F) WPD = waterside pressure drop (psi & ft. of hd.) Conversion Table - to convert inch-pound (English) to S-I (Metric) Air Flow Water Flow Ext Static Pressure Water Pressure Drop Airflow (L/s) = CFM x Water Flow (L/s) = gpm x ESP (Pa) = ESP (in of wg) x 249 PD (kpa) = PD (ft of hd) x 2.99 LC386-4

5 Selection Procedure Step 1 Step 2 Determine the actual heating and cooling loads at the desired dry bulb and wet bulb conditions. Obtain the following de sign 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 ap pro pri ate tables and find the proper indicated water flow 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 flow and water temperature. Read the total and sensible cooling capacities (Note: interpolation is per mis si ble, ex trap o la tion is not). 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...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 pa ram e ters: Entering Water Temp...90 F Water Flow (Based upon 12 F rise in temp.) GPM Air Flow CFM Step 3, 4 & 5 HP Selection: Step 5 Step 6 Step 7 Step 8 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. Determine the correction factors associated with the variable factors of dry bulb and wet bulb. 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 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. 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 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 in doubt, undersize slightly for best performance. After making our preliminary selection (TRC12), we enter the tables at design water flow and water tem per a ture and read Total Cooling, Sens. Cooling and Heat of Rej. ca pac i ties: 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 Cor rect ed Corrected Total Cooling = 10,800 x x =10,056 Corrected Sens Cooling = 9,200 x x = 9,134 Corrected Heat of Reject = 13,900 x x = 13,037 Step 8 Water Temperature Rise Calculation & As sess ment: Actual Temperature Rise F When we compare the Corrected Total Cooling and Corrected Sensible Cooling figures 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 figure is slightly undersized as recommended, when compared to the actual in di cat ed load. LC386-5

8 Performance Data Selection Notes For operation in the shaded area when water is used in lieu of an antifreeze solution, the LWT (Leaving Water Temperature) must be calculated. Flow must be maintained to a level such that the LWT is maintained above 42 F [5.6 C] when the JW3 jumper is not clipped (see example below). Otherwise, appropriate levels of a proper antifreeze solution should be used in systems with leaving water temperatures of 42ºF [5.6 C] or below and the JW3 jumper should be clipped. This is due to the potential of the refrigerant temperature being 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 (Entering 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 Minute. TD = HE / (GPM x 500) TD = 22,500 / (4.5 x 500) Heating - EAT 70 F EER HC kw HE LAT COP ed TD = 10 F LWT = EWT - TD LWT = = 40 F 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 = = 42.5 F, which is above 42 F EWT, and is acceptable for this application. LC386-8
