What's New with Bryant Geothermal's GT-PG?

Puron

Puron R-407C and R-134A, is seen as the future of all refrigerants used worldwide. HFC-410A characteristics compared to R-22 are:

• Binary and near azeotropic mixture of 50% R-32 and

• Higher efﬁ ciencies (50-60% higher operating pressures)

•

• Virtually no glide. Unlike other alternative refrigerants, the

MERV 11 2” Pleated ﬁ lter All GT-PG units include a factory installed 2” ﬁ lter rack/duct collar with a 2” pleated high efﬁ ciency MERV 11 air ﬁ lter. The MERV (minimum efﬁ ciency reporting value per ASHRAE Standard 52.2) design features ultra low velocity (<300 fpm) for extended ﬁ lter life, low pressure drop (0.13 – 0.18 in. wg.) and high particulate efﬁ ciency (size E1=41%, E2=69% and E3=87%). The pleated design and low velocity combine to allow the ﬁ lter to store a large amount of dirt and result in a practical replacement life of up to 6 months.

Tin-Coated Air Coil

All Bryant Geothermal GTPG Series models feature a tin-coated air-coil. This coating process will provide years of protection against corrosion from airborne chemicals resulting from modern building material out gassing and most environmental chemicals found in the air. Modern building materials such as counter-tops, ﬂ oor coverings, paints and other materials can “outgas” chemicals into the home’s air. Some of these chemicals are suspected of contributing to corrosion in the air coils found in both traditional and geothermal heating and cooling equipment. Corrosion often results in refrigerant leaks and eventual failure of the air coil costing hundreds of dollars to replace. Studies have also shown that these air coil coatings improve moisture shedding and therefore improve a unit’s moisture removal capability resulting in a more comfortable home. The GT-PG Series is your assurance of both maximum air coil life and comfort.

rates. Therefore, refrigerant can be added if necessary without recovering the charge.

MERV 11

Copeland – turned theory into practical reality, using sophisticated, computer-assisted design and manufacturing methods to achieve the critical tolerances required. In the years since, Copeland has become the leader in scroll compressor applications, with nine scroll manufacturing facilities on three continents and millions of units installed worldwide.

Copeland Scroll compressors employ two identical, concentric scrolls, one inserted within the other. One scroll remains stationary as the other orbits around it. This movement draws gas into 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 in the ﬁ xed scroll. During each orbit, several pockets are compressed simultaneously, so operation is virtually continuous.

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 existing R-22 units. HFC-410A units can reach the industry’s highest efﬁ ciency levels. HFC-410A scrolls also offer sound advantages to other compressor technologies, typically operating several decibels quieter than comparable R-22 models. The result is unsurpassed reliability and virtually silent operation.

Copeland Scroll Compressor

There’s a reason 9 out of every 10 scroll compressors installed are Copeland. With over 15 years of painstaking R & D and rigid production controls, Copeland is able to build the most reliable, efﬁ cient and quiet scroll compressors in the world.

The concept of compressing a gas by turning one involute form – or “scroll” – against another around a common axis is nearly a century old. It wasn’t until the late 1980s, however that one company –

About AHRI/ISO/ASHRAE 13256-1

AHRI/ASHRAE/ISO 13256-1 (Air-Conditioning and Refrigeration Institute/American Society of Heating, Refrigerating and Air Conditioning Engineers/International Standards Organization) is a certiﬁ cation standard for water-source heat pumps used in the following applications:

• WLHP (Water Loop Heat Pump – Boiler/Tower)

• GWHP (Ground Water Heat Pump – Open Loop)

• GLHP (Ground Loop Heat Pump – Geothermal) The directory at http://www.ahrinet.org/ is constantly being updated and immediately available on the Internet. All ratings 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 testing 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 initial failure is a performance test, the manufacturer must obsolete all units within 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 within the same basic model group. Bryant Geothermal takes certiﬁ cation seriously. We were recently awarded a certiﬁ cate for consecutive years of no AHRI failures.

Temperatures used in AHRI certiﬁ cation standards are S.I. (Système International – metric) based. For example, typical catalog data for cooling is shown at 80°F DB/67°F WB [26.7°C DB/19.4°C] entering air temperature, but the AHRI standard for cooling is 80.6°F DB/66.2°F WB [27°C DB/19°C], since it is based upon whole numbers in degrees Celsius. Water and air temperatures for the standard are shown below.

Data certiﬁ ed by AHRI include heating/cooling 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 pumping Watts. Within each model, only one water ﬂ ow rate is speciﬁ ed for all three groups, and pumping Watts are calculated using the formula below. This additional power is added onto the existing power consumption.

• Pump power correction = (gpm x 0.0631) x (Press Drop x 2990)/300 Fan power is corrected to zero external static pressure using the equation below. The nominal airﬂ ow is rated at a speciﬁ c external static

pressure. This effectively reduces the power consumption of the unit and increases cooling capacity but decreases heating capacity.

• Fan Power Correction = (cfm x 0.472) x (esp x 249)/300 Capacities and efﬁ ciencies are calculated using the following equations:

• ISO Cooling Capacity = Cooling Capacity (Btuh) + [Fan Power Correction (Watts) x 3.412]

• ISO EER Efﬁ ciency (Btuh/W) = ISO Cooling Capacity (Btuh)/[Power Input (Watts) – Fan Power Correction (Watts) + Pump Power Correction (Watts)]

• ISO Heating Capacity = Heating Capacity (Btuh) – [Fan Power Correction (Watts) x 3.412]

• ISO COP Efﬁ ciency (Btuh/Btuh) = ISO Heating Capacity (Btuh) x 3.412/[Power Input (Watts) - Fan Power Correction (Watts) + Pump Power Correction (Watts)]

Performance Data Selection Notes

For operation in the shaded area when water is used in lieu of an anti-freeze solution, the LWT (Leaving Water Temperature) must be calculated. Flow must be maintained to a level such that the LWT is maintained 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 in systems with leaving water temperatures of 40°F 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) TD = 10°F LWT = EWT - TD LWT = 50 - 10 = 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 ﬂ ow rates will be required (open loop systems, for example, require at least 2 gpm/ton when EWT is below 50°F).

Interpolation is permissible; extrapolation is not. All entering air conditions are 80°F DB and 67°F WB in cooling, and 70°F DB in heating. AHRI/ISO certiﬁ ed conditions are 80.6°F DB and 66.2°F WB in cooling and 68°F DB in heating. Table does not reﬂ ect fan or pump power corrections for AHRI/ISO conditions. All performance is based upon the lower voltage of dual voltage rated units. Operation below 40°F EWT is based upon a 15% methanol antifreeze solution. Operation below 60°F EWT requires optional insulated water/refrigerant circuit. See performance correction tables for operating conditions other than those listed above. For operation in the shaded areas, please see the Performance Data Selection Notes.
