Unit FeaturesTHE TRANQUILITY MODULAR WATERTO-WATER (TMW) SERIESUNIT FEATURESThe Tranquility Modular Water-to-Water (TMW) Seriesoffers high efficiency and high capacity with advancedfeatures, quiet operation and application flexibility atcompetitive prices. As ClimateMaster’s largest water-towater unit, the TMW Series can be used for radiant floorheating, snow/ice melt, chilled water for fan coils, industrialprocess control, potable hot water generation*, hot/chilledwater for make-up air, and many other types of HVAC andindustrial applications that require cost effective heated orchilled water.The Tranquility Modular Water-to-Water (TMW) Seriesexceeds ASHRAE 90.1 efficiencies, and also usesEarthPure (HFC-410A) zero ozone depletion refrigerant,making it an extremely environmentally-friendly option. Theunit is eligible for additional LEED (Leadership in Energyand Environmental Design) points because of the “green”technology design.Available in 3 to 28 ton capacities (10.6 kW and 100 kW),the TMW Series provides high capacity in a small footprint,which saves mechanical room space. The TMW Serieshas an extended range refrigerant circuit (refrigerant andwater circuit insulation is standard), capable of groundloop (geothermal) applications as well as water loop(boiler-tower) applications. Standard features are many.Microprocessor controls, galvanized steel cabinet, polyesterpowder coat paint and TXV refrigerant metering device arejust some of the features of the flexible TMW Series. Theuniquely-designed coaxial heat exchangers are designed formany years of reliable operation. Size 036, 060, 120, 170 & 340Copeland scroll compressor(s)Dual independent refrigeration circuits on size 340Exclusive single side service access (front of unit) allowsmultiple units to be installed side-by-side for largecapacity installationsTop water connections, staggered for ease of manifoldingmultiple unitsExceeds ASHRAE 90.1 efficienciesHeavy gauge galvanized steel construction with polyesterpowder coat paint and stainless steel front access panelsInsulated compressor compartmentSmall footprintTXV metering devicesExtended range (20 to 110 F, -6.7 to 43.3 C) operationMicroprocessor controls standard (optional DXM and/orDDC controls)BACnet, Modbus and Johnson N2 compatibility optionsfor DDC controlsCompressor “run” and “fault” lights on the front ofthe cabinetSeven safeties standardOptions include UltraQuiet sound attenuation packageand cupro-nickel heat exchanger(s)* Requires field supplied secondary heat exchanger.ClimateMaster’s dual-isolated compressor mounting andheavy gauge steel cabinet helps make the TMW Seriesthe quietest large capacity water-to-water unit on themarket. Scroll compressor(s) operate quietly, and providepart load operation (models 120 and 340) for capacitycontrol. Options such as DDC controls and UltraQuiet soundattenuation package allow customized design solutions. Forease of installation and service, access to the refrigerationservice and electrical control panel is located at the front ofthe unit, allowing units to be installed side-by-side for largecapacity applications (see below).The TMW Series water-to-water heat pumps are designedto meet the challenges of today’s HVAC demands with ahigh efficiency, high value solution.ClimateMaster works continually to improve its products.

Selection ProcedureStep 1 Determine the actual heating and/or cooling loads at theapplicable source (building loop) water temperature/flowrate and load water temperature/flow rate. The sourceheat exchanger is the condenser in cooling/evaporatorin heating; the load heat exchanger is the evaporator incooling/condenser in heating.Step 2 Obtain the following design parameters: EnteringExample Equipment Selection for HeatingStep 1 Load Determination:Assume we have determined that the application will be heatingonly (radiant floor) for a large commercial warehouse, and that theappropriate heating load at design conditions is as follows:Total heating.210,000 BTUHsource/load water temperature, source/load water flowrate in GPM and water flow pressure drop. Water flowrate is generally between 2.25 and 3.00 GPM/ton forclosed loop (boiler/tower and geothermal) systems, andbetween 1.5 and 2.0 GPM/ton for open loop (well water)systems. Unit water pressure drop should be kept asclose as possible to each other to make water balancingeasier. Go to the appropriate tables and find the properindicated water flow and water temperature.Step 3 Determine application requirements. Water-to-waterapplications are almost always designed for a particularinstallation, which will change how the data tables areused for unit selection. For example, a water-to-waterunit used for radiant floor heating on a geothermalclosed loop is significantly different in unit selectionfrom a water-to-water unit on a boiler/tower applicationused for generating chilled water for fan coil units. It isespecially important to note that the load water flowrate must be maintained above minimum flow rates asshown in the data tables for proper refrigerant circuitoperation and unit longevity. For example, most radiantfloor applications require buffer (storage) tanks becausethe flow rate through the floor is usually lower thanthe minimum flow rate for the water-to-water unit.Therefore, selection of the heat pump is dependent uponmaintaining a certain tank temperature and unit loadflow rate. There would be a pump between the heatpump and the buffer tank, and a pump(s) between thebuffer tank and radiant floor to maintain design flow rateon both sides.Step 2 Design Conditions:Entering source temperature.30 F (geothermal closed loop)Source flow rate.53 GPMEntering load temperature.100 FLoad flow rate.53 GPMSteps 3, 4, 5 HP Selection:We enter the tables at design source water temperature and flowrate, and select the appropriate load water temperature and flowrate. A TMW340 at design conditions supplies 211,100 BTUH,which meets the design heating load requirement.Step 4 Enter tables at the design source water temperatureand flow rate. Choose the appropriate load watertemperature and flow rate. Read the total heating orcooling capacities (Note: interpolation is permissible;extrapolation is not).Step 5 If the units selected are not within 10% of the loadcalculations, then review what effect changing the GPMand water temperature would have on the capacities. Ifthe desired capacity cannot be achieved, select the nextlarger or smaller unit and repeat the procedure.ClimateMaster works continually to improve its products.
