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.
The Sun Frost RF-19 and F-19 use a quiet and highly efficient fan
to help cool the condenser; on other models, the condensers are
cooled passively. Because of the efficient design of the Sun Frost,
the compressors used 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
EFFICIENT 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 which 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. The accompanying cost of the solar
power system is similarly reduced. The SUN FROST RF-16 12 volt DC
model consumes 20 KWH per month, or an average of 53 amp hours per
day. By contrast, conventional refrigerators typically consume about
110 KWH per month or 305 amp hours per day. Producing the 110 KWH
needed to run this refrigerator on a solar power system would require
an investment of around $12,000 in hardware, batteries, and inverter.
A Sun Frost 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.
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 five 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
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 RF-16 and RF-19 refrigerators
and a 24 inch high cabinet for the Sun Frost RF-12. 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

existing kitchen cabinets. SUN FROST can
manufacture base cabinets which match the refrigerator's trim and
color as shown in the photos on our Models page.
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.
