Cooling Performance that Matches the Needs
Most refrigeration products run at two speeds. One of the
speeds is high and the other is off. While this has been a
suitable technology for many years, the need to conserve
energy has recently become more important.
One way to decrease operating costs is to operate the
system at a lower speed over a longer period of time. The
most efficient operation would occur if the system could
be fine tuned to run continuously at a level that constantly
matched the cooling requirements.
This is a lot like your car. In stop and go driving in a city
environment your mileage will be lower than when you set
the cruise control and are out on the open country roads.
The energy needed to start your car moving and get it up
to twenty-five miles per hour is greater than the energy
needed to keep it moving at fifty-five miles per hour. You
can always feel comfortable knowing the power is there to
quickly accelerate if needed but you can keep it in reserve
and save money until the need arises.
Dacor Built-in Refrigerators use variable capacity cooling
to match the needs of the user. Variable Capacity Cooling
is not brand new technology. It is a more expensive
technology. The demand in the US has not been strong enough to encourage refrigerator
manufacturers to include this technology in their standard product line. This technology has
been in use in Europe and Asia where the power infrastructure is not as well developed and
energy conservation is of higher concern. A true luxury product should include the newest
technology and features just as a true luxury car should have all the latest features and
options available.
By providing Variable Capacity the Dacor Built-in products provide high performance power
when needed and high efficiency all of the time.
While this product line is not currently Energy Star™ rated, the performance is just short of
the requirements. The testing procedures are very specific and the laboratory tests place this
product just under the threshold needed. In actual use, this product line could actually result
in lower energy bills than expected, depending on the use patterns.
In the long run, slow and steady will win the race and the customer who is interested in peak
performance will not be disappointed with the results of Variable Capacity Cooling.
Sound Performance Beyond Many Expectations
About the only time we become concerned with the noise our refrigerator makes is either
when the sound drastically changes and service is needed, or when it is loud enough to be
heard in a quiet house on a sleepless night.
Dacor Built-in Refrigerators were designed from the start to be some of the quietest on
the market. Special insulation is included to limit the noise heard outside of the cabinet.
Bumpers have been added to prevent vibration. The Variable Capacity Compressor has a
lower volume at a lower speed. Even the control area is insulated so that the relays that
switch different circuits are barely audible.
The end result is a system that will only be heard when the user is trying to hear it. It will be
seldom that the users will even notice when the system is running.
There are some noises that are normal. The following page identifies some of the normal
noises and indicates what the source could be.
