Heat Pumps
38YRA Profile
 No
matter what Mother Nature has in store outdoors, Carrier
helps you control your indoor weather with superior products
like the 38YRA heat pump. Maintaining comfortable
temperatures all year long is just one way the 38YRA
improves your indoor weather. As a part of our Silencer
System series, this heat pump incorporates features designed
to ensure operation that is so quiet, you might not notice
that your system is running. And, because it's designed and
built by Carrier, the 38YRA offers dependability backed by
nearly a century of indoor weather expertise.
 The
Silencer System is Carrier's exclusive design that ensures
extra-quiet, unobtrusive heat pump operation. With this
unique system, it would take about ten 38YRA heat pumps, all
running at the same time, to create the same amount of noise
generated by one typical heat pump. This stunning
performance is made possible through a combination of
components and design features developed by Carrier
engineers.
Amazingly quiet operation
is the result of Carrier's expertise in heat pump
design. Sound from your heat pump is the result of
compressor operation and air movement through the unit.
Carrier has dramatically reduced compressor noise by
wrapping the compressor with a sound hood. In addition, the
compressor is attached to a laminated steel vibration
isolator plate, which eliminates sound being transferred
through the unit. Carrier's patented Silencer System top
allows the air to pass smoothly through the unit. Carrier's
research center designed the fan blades in its heat pumps to
be extra efficient at moving air. Finally, the discharge
muffler eliminates the humming sound sometimes heard in the
home, the result of pulsations in the refrigerant tubing.
It's a total package that provides soothing, quiet,
efficient comfort that is felt and not heard.
You
can keep comfortable, even when the heating and cooling
bills arrive, because the 38YRA offers money-saving energy
efficiency. With exceptional efficiency ratings of up to
9.2 HSPF (Heating Seasonal Performance Factor) and up to
15.0 SEER (Seasonal Energy Efficiency Ratio), this heat pump
easily saves money on operation when compared to a typical,
older model that is being replaced. And, when the 38YRA is
matched with a variable speed fan coil, it is one of the
most efficient systems available.
This
chart can be used as an estimate of just how much
money you can save by investing in a high efficiency
system. If your old system was rated at 8 SEER, then
by purchasing a 15 SEER system, you should be able to
reduce the cost to cool your home by almost 50%. This
can add up to a significant savings over the life of
the product.
 Carrier's
reputation for reliability is one that has been developed
and maintained for nearly one hundred years. Quite
simply, our name has lasted because we build products that
last. Components like our high and low pressure switches and
TimeGuard II™ protect the unit's most valuable single
component: the compressor. On the outside, Carrier's
WeatherArmor III cabinet protects the unit against damage
from rocks and sticks, as well as lawn maintenance
equipment, to provide years of good looks and durability.
This may seem like a small detail, but it's a perfect
example of why homeowners nationwide put their trust in
Carrier for innovative solutions to their indoor weather
needs.
38YRA Features
Exceptionally quiet operation is achieved with
Carrier's Silencer System. Components of this system
include:
- Silencer System
top which allows air to glide smoothly through the
system.
- Highly efficient
fan designed to quietly move outdoor air.
- Deluxe compressor
sound hood absorbs compressor noise.
- Compressor vibration
isolator plate prevents vibrational noise from being
transferred to the base pan.
- The discharge
muffler assures quiet indoor comfort by minimizing
refrigerant pulsation through the refrigerant
lines.
Smooth, efficient
operation is delivered by the scroll compressor.
Efficient refrigerant compression is key to the heat pump's
performance.
For durable service,
the WeatherArmor III cabinet combines a heavy-duty steel
cabinet, ceramic-coated screws and our enhanced coil guard
for the ultimate in lasting toughness and coil protection.
Quality is enhanced
with the Carrier base pan. Designed to properly drain water
and debris from the unit, the chance for corrosion is
greatly reduced.
Reliable performance is provided by TimeGuard
II™ which prevents unnecessary
wear and tear on the compressor due to rapid restarts after
shutdown.
System protection
occurs as the high and low pressure switches monitor
refrigerant pressure and shut down the unit before permanent
damage can occur to the compressor.
Added reliability is
provided as the accumulator protects the compressor from
damage if liquid refrigerant flows back into the
system
