3 ClimateMaster Geothermal Heatg and Coolg What's New with ClimateMaster's Tranquility 20? EarthPure Refrigerant EarthPure is a non-chlore based (HFC-410A) refrigerant, that with R-407C and R-134A, is seen as the future of all refrigerants used worldwide. HFC-410A characteristics compared to R-22 are: Bary and near azeotropic mixture of 50% R-32 and 50% R-125. Higher effi ciencies (50-60% higher operatg pressures) Zero ozone depletion potential and low global warmg potential. Virtually no glide. Unlike other alternative refrigerants, the two components HFC-410A have virtually the same leak rates. Therefore, refrigerant can be added if necessary without recoverg the charge. MERV 11 2 Pleated filter All Tranquility 20 units clude a factory stalled 2 fi lter rack/ duct collar with a 2 pleated high effi ciency MERV 11 air fi lter. The MERV (mimum effi ciency reportg value per ASHRAE Standard 52.2) design features ultra low velocity (<300 fpm) for extended fi lter life, low pressure drop ( wg.) and high particulate effi ciency (size E1=41%, E2=69% and E3=87%). The pleated design and low velocity combe to allow the fi lter to store a large amount of dirt and result a practical replacement life of up to 6 months. MERV 11 T Plated Air Coil All ClimateMaster Tranquility 20 Series models feature either a t-plated or allalumum air coil. These will provide years of protection agast corrosion from airborne chemicals resultg from modern buildg material out gassg and most environmental chemicals found the air. Modern buildg materials such as counter-tops, fl oor covergs, pats and other materials can outgas chemicals to the home s air. Some of these chemicals are suspected of contributg to corrosion the air coils found both traditional and geothermal heatg and coolg equipment. Corrosion often results refrigerant leaks and eventual failure of the air coil costg hundreds of dollars to replace. Studies have also shown that these air coil coatgs improve moisture sheddg and therefore improve a unit s moisture removal capability resultg a more comfortable home. The Tranquility 20 Series is your assurance of both maximum air coil life and comfort. the critical tolerances required. In the years sce, Copeland has become the leader scroll compressor applications, with ne scroll manufacturg facilities on three contents and millions of units stalled worldwide. Copeland Scroll compressors employ two identical, concentric scrolls, one serted with the other. One scroll remas stationary as the other orbits around it. This movement draws gas to the compression chamber and moves it through successively smaller pockets formed by the scroll s rotation, until it reaches maximum pressure at the center of the chamber. There, it s released through a discharge port the fi xed scroll. Durg each orbit, several pockets are compressed simultaneously, so operation is virtually contuous. Recently, Copeland produced its 500,000th Scroll compressor with the environmentally sound refrigerant HFC-410A. Field results have shown that HFC-410A units with Copeland Scroll compressors offer nearly 30% lower failure rates versus existg R-22 units. HFC-410A units can reach the dustry s highest effi ciency levels. HFC-410A scrolls also offer sound advantages to other compressor technologies, typically operatg several decibels quieter than comparable R-22 models. The result is unsurpassed reliability and virtually silent operation. Other New Features Stylish two-tone look with textured black powder coat pat and staless steel front access panels. Liftout handles for front access panels. Corrosion and sta resistant staless steel dra pan with extra slope designed. Factory mounted fi lter drier for trouble free reliability. Easy access low profi le horizontal control box. Double isolated compressor for quiet and vibration free operation. Foil faced sulation air handlg compartment to allow easy cleang and prevent microfi ber troduction to the air stream. Open Service-Friendly Cabet ( i.e, all components compressor section can be serviced from the front). Copeland Scroll Compressor There s a reason 9 out of every 10 scroll compressors stalled are Copeland. With over 15 years of pastakg R & D and rigid production controls, Copeland is able to build the most reliable, effi cient and quiet scroll compressors the world. The concept of compressg a gas by turng one volute form or scroll agast another around a common axis is nearly a century old. It wasn t until the late 1980s, however that one company Copeland turned theory to practical reality, usg sophisticated, computer-assisted design and manufacturg methods to achieve Residential Products Technical Guide 3

7 ClimateMaster Geothermal Heatg and Coolg About AHRI/ISO/ASHRAE About AHRI/ISO/ASHRAE AHRI/ASHRAE/ISO (Air-Conditiong and Refrigeration Institute/American Society of Heatg, Refrigeratg and Air Conditiong Engeers/International Standards Organization) is a certifi cation standard for water-source heat pumps used the followg applications: WLHP (Water Loop Heat Pump Boiler/Tower) GWHP (Ground Water Heat Pump Open Loop) GLHP (Ground Loop Heat Pump Geothermal) The directory at is constantly beg updated and immediately available on the Internet. All ratgs are submitted by the manufacturer for certifi cation, and must be approved by AHRI. Therefore, there is a signifi cant difference between AHRI certifi ed and AHRI rated. Thirty percent of a manufacturer s basic models must be tested each year. AHRI selects models at random from stock for testg on the basis of its evaluation of a participant s certifi cation data. Units that fail one or more certifi ed test (90% of declared performance or lower) may be declared defective. If the itial failure is a performance test, the manufacturer must obsolete all units with the same basic model group or elect to have a second sample tested. If the second unit fails a performance test, it must be obsoleted, together with all units with the same basic model group. ClimateMaster takes certifi cation seriously. We were recently awarded a certifi cate for consecutive years of no AHRI failures. Temperatures used AHRI certifi cation standards are S.I. (Système International metric) based. For example, typical catalog data for coolg is shown at 80 F DB/67 F WB [26.7 C DB/19.4 C] enterg air temperature, but the AHRI standard for coolg is 80.6 F DB/66.2 F WB [27 C DB/19 C], sce it is based upon whole numbers degrees Celsius. Water and air temperatures for the standard are shown below. Test Condition Comparison Table WLHP GWHP GLHP Coolg Enterg Air Temperature - DB/WB F [ C] Enterg Water Temperature - F [ C] Fluid Flow Rate 80.6/66.2 [27/19] 86 [30] * 80.6/66.2 [27/19] 59 [15] * 80.6/66.2 [27/19] 77 [25] * Heatg Enterg Air Temperature - DB/WB F [ C] Enterg Water Temperature - F [ C] Fluid Flow Rate 68 [20] 68 [20] * 68 [20] 50 [10] * 68 [20] 32 [0] * *Flow rate is specified by the manufacturer Data certifi ed by AHRI clude heatg/coolg capacities, EER (Energy Effi ciency Ratio Btuh per Watt) and COP (Btuh per Btuh) at the various conditions shown above. Pump power correction is calculated to adjust effi ciencies for pumpg Watts. With each model, only one water fl ow rate is specifi ed for all three groups, and pumpg Watts are calculated usg the formula below. This additional power is added onto the existg power consumption. Pump power correction = (gpm x ) x (Press Drop x 2990)/300 Fan power is corrected to zero external static pressure usg the equation below. The nomal airfl ow is rated at a specifi c external static pressure. This effectively reduces the power consumption of the unit and creases coolg capacity but decreases heatg capacity. Fan Power Correction = (cfm x 0.472) x (esp x 249)/300 Capacities and effi ciencies are calculated usg the followg equations: ISO Coolg = Coolg (Btuh) + [Fan Power Correction (Watts) x 3.412] ISO EER Effi ciency (Btuh/W) = ISO Coolg (Btuh)/[Power Input (Watts) Fan Power Correction (Watts) + Pump Power Correction (Watts)] ISO Heatg = Heatg (Btuh) [Fan Power Correction (Watts) x 3.412] ISO COP Effi ciency (Btuh/Btuh) = ISO Heatg (Btuh) x 3.412/[Power Input (Watts) - Fan Power Correction (Watts) + Pump Power Correction (Watts)] Residential Products Technical Guide 7

12 Tranquility 20 () Series 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 anti-freeze should be used systems with leavg water temperatures of 40 F 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. Performance capacities shown thousands of Btuh Heatg - EAT 70 F R HW Airflow HC kw HE LAT COP H /A N/A N/A N/A TD = HE/(GPM x 500) 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).
