Carrier Indoor & Outdoor Split Geothermal Heat Pumps - Rev.: 08/10/05
Rounding Out the Product Line
Building upon the overwhelming market success of
the GT-PX packaged unit, the split system uses the
same components in a more
fl
exible con
fi
guration.
The GT-PX split system compressor section can be
coupled with a variety of air handlers and add-on
furnace coils to achieve the highest ef
fi
ciencies of
any split system heat pump on the market today,
while still providing the
fl
exibility of an all-electric or
dual fuel system and a remote compressor section
location. Split systems are often used in areas where
it would be dif
fi
cult to install a packaged unit, such as
in an attic or crawl space.
Puron
®
Refrigerant
Puron
®
is a non-chlorine 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:
• Binary and near azeotropic mixture of 50% R-32
and 50% R-125.
• Higher ef
fi
ciencies (50-60% higher
operating pressures).
• Zero ozone depletion potential and low global
warming potential.
• Virtually no glide. Unlike other alternative
refrigerants, the two components in HFC 410A
have virtually the same leak rates. Therefore,
refrigerant can be added if necessary without
recovering the charge.
Copeland Two-Stage Scroll Compressor
Achieve a greater level of comfort.
The Copeland Scroll UltraTech™
provides superior comfort than
fi
xed-capacity compressors by
incorporating a revolutionary two-
step design. With a unique 67%
part-load capacity step, systems
with UltraTech™ maintain precise
temperature levels and lower relative
humidity. This eliminates uneven peaks and valleys
and allows for steady cooling comfort. Homeowners
now have a better, more ef
fi
cient way to power
their heating and cooling system, raising their level of
comfort, while lowering energy bills. So when your
customers need a new heating and cooling system,
make sure it has the best technology inside – the
Copeland Scroll UltraTech™ compressor.
Save with superior ef
fi
ciency. Over 40% of summer
utility bills can come from the air conditioner
compressor operation. A system with the Copeland
Scroll UltraTech™ compressor delivers higher
ef
fi
ciency than any other single compressor system.
In fact, systems with UltraTech™ provide up to 60%
greater energy ef
fi
ciency as compared to 10 SEER
systems – which can save homeowners hundreds
of dollars a year in energy costs.
Take it easy with quieter control. Copeland
Scroll UltraTech™ is remarkably quiet at both
full- and part-load capacity. In fact, it is up to four
times quieter than a reciprocating compressor.
Homeowners can enjoy its superior ef
fi
ciency and
comfort without having to hear the operation.
Learn the beauty of the design. With Copeland Scroll
UltraTech™, two internal bypass ports enable the
system to run at 67% part-load capacity for better
ef
fi
ciency
and humidity
control. Based
on demand,
the modulation
ring is
activated,
sealing the bypass ports and instantly shifting capacity
to 100%. Take advantage of “shift on the
fl
y” stage
changing (no stopping and starting required like other
two-stage compressors).
Choose proven scroll performance. While Copeland
Scroll UltraTech™ builds on established scroll
technology, it is still a scroll at heart, which means
it operates with fewer moving parts, no volumetric
ef
fi
ciency drop-off or compression leakage. The result
is unsurpassed reliability and virtually silent operation
for both indoor and outdoor applications.
