 Efficiency
- Plus
The Sun Frost refrigerator employs
an array of design innovations to achieve its exceptionally low
energy consumption. The cooling system on the Sun Frost is top mounted.
This configuration reduces energy consumption several ways. The
heat generated by the compressor and condenser (black coils on the
back of many refrigerators) does not re-enter the refrigerator and
also with a cooler running condenser, the efficiency of the cooling
system is increased.
Quiet Operation
The condensers on Sun Frost refrigerators and freezers are cooled
passively, except our RF19 and F19 models, which use a quiet and
highly efficient fan to help cool the condenser. Because of the
efficient design of the Sun Frost, the compressors used run
less often, are much smaller and produce correspondingly less noise
than those found on a conventional refrigerator. These features
make the Sun Frost much quieter than a conventional AC refrigerator.
 Simple
Defrost System
Defrosting a Sun Frost is a simple process. Frost build-up in the
Sun Frost freezer is very slow because there is no air circulating
between the freezer and refrigerator sections. The ice that forms
in the freezer collects primarily on the ceiling. When defrosting
the freezer section, the contents of the freezer may be transferred
to the refrigerator section so they remain frozen. After the refrigerator
has been turned off for about twenty minutes, the ice is easily
removed in large pieces. There is no mop-up because the ice does
not need to be melted, only separated from the flat ceiling.
Superior Storage Conditions
Sun Frost refrigerators keep food fresher by maintaining high humidity.
This prevents freezer burn and wilting caused by water loss in food.
Since there is minimal water loss in foods stored in a Sun Frost,
foods often last two to three times longer than in conventional
refrigerators. In typical refrigerators,
water, which is part of stored food, is transformed into ice on
the freezer's cooling coils. This process results in the dehydration
of fruits and vegetables, increases energy consumption, and accelerates
frost build-up. In a conventional refrigerator, high humidity is
achieved by storing food in airtight containers, which creates high
humidity conditions, but cuts off the food's oxygen supply. Without
oxygen, plant cells break down more rapidly, which decreases shelf
life. The Sun Frost allows you to store food in breathable containers,
such as paper bags, often more than doubling storage life.
 Fewer
Solar Panels
The Sun Frost refrigerator typically reduces refrigerator energy
consumption by a factor of five compared to the typical household
refrigerator currently in use. The accompanying cost of the solar
power system is similarly reduced. The Sun Frost RF16 12 volt DC
model consumes 15 KWH per month, or an average of 42 amp hours per
day. Producing the 110 KWH needed to run the typical refrigerator
on a solar power system would require an investment of around $12,000
in hardware, batteries, and inverter. A Sun Frost RF16 will reduce
this cost by a factor of at least six because of its increased efficiency
and the elimination of inverter losses. Inverters convert DC battery
power to 120V AC at an energy loss of about 10%.
Reliable
The cooling system of the Sun Frost refrigerator contains a minimal
number of moving parts. Both the DC and AC compressors incorporate
highly reliable, hermetically sealed, brushless motors. The efficient
thermal design of Sun Frost refrigerators also contributes to their
reliability. The top-mounted cooling system runs at a lower temperature
than most, which prolongs the life of the system's lubricants and
reduces mechanical strain on the compressor. The cooling system
should provide well over 15 years of trouble-free operation.
 Cooler
Summer Kitchen
During the summer, a typical refrigerator adds as much heat to your
kitchen as a 1000 watt heater running four hours per day! The energy
needed by your air conditioner to remove this excess heat will be
about half the energy consumed by your refrigerator. Increasing
the cost of running your refrigerator by an additional 50%. By producing
much less waste heat than a conventional refrigerator, a Sun Frost
makes your kitchen more comfortable and reduces the cost of air-conditioning
your home.
More Sensible use of Kitchen Space
Sun Frost refrigerators are designed to be mounted on a cabinet.
With the refrigerator raised, all stored food will then be at a
convenient height. In addition, a cabinet beneath the refrigerator
provides much more accessible storage space than a ceiling mounted
cabinet. The cabinet could be built by the homeowner to match other
kitchen cabinets or supplied by Sun Frost. Sun Frost manufactures
a 13-inch high cabinet for the Sun Frost RF16 and RF19 refrigerators
and a 24-inch high cabinet for the Sun Frost RF12. Each cabinet
has two large side-by-side drawers. A Sun Frost refrigerator can
be placed against a wall, minimizing floor area utilized. It will
not have to be moved for either cleaning or servicing.
 Rugged
Design
Sun Frost refrigerators and freezers are ideal
for use in boats, RVs and conversion buses. All Sun Frost
refrigerators are completely rust-proof. There is no need
to level the refrigerator, and vibration will not affect its operation.
Sun Frost refrigerators can also run directly off of batteries,
so no generator is necessary.
Custom Styling and Finishes
Each custom built Sun Frost refrigerator is available in more than
100 colors of high-pressure laminate and many natural wood finishes.
The spacious interior, made from sturdy fiberglass-reinforced plastic,
is exceptionally easy to clean, with no exposed ducts, tubing or
inaccessible corners. The adjustable door shelves can accommodate
half-gallon beverage containers, while adjustable glass shelves
line the refrigerator section. Ask us about our new
stainless steel option!
