DC Intake/Exhaust Fans
CFM =
Cubic Feet per Minute
12 or 16 runs on 12 to 24 volt DC. These efficient and
quiet air movers use a reversible permanent magnet motor and a three wing
aluminum blade. Nice for ventilating houses, attics, greenhouses, barns and food
dehydrators. Fans can be connected to a solar module and run when the sun shines
or connected to battery to run anytime. Use a 10 watt solar module for 12 fans
or 20 watt for 16 fans. Fans will run faster and more hours per day with a
larger solar module or with a LCB or PPT controller.
The 12 fan delivers about 500 CFM on 12 volts at 0.7 amp and more air on 24
volts at 2 amps. 14-3/8" x 6"
The 16" fan delivers about 700 CFM on 12 volts at 1 amp and more air on 24 volts
at 2.5 amps. 20" x 20" x 7"
Ring frame fans can be mounted to plywood to fit a non-round hole.

60 " Vari-Cyclone Fan
with
Gossamer Wind Technology for 30% more air flow with same power
AC fans
can use 10 time the amps!
DC Ceiling Fan. The Vari-Cyclone with the new blade
design breakthrough, will outperform any other DC-powered ceiling fan
available. In tests conducted by the
Florida Solar Energy Center, the 3-blade Vari-Cyclone showed a 22.8%
increase in cubic feet per minute (CFM) over the 5-blade, 42" Vari-Fan. The
Vari-Cyclone can bring the warm air down from your high ceilings, blow a
cooling breeze and keep the air circulating on your porch, classroom,
warehouse, etc. The Vari-Cyclone will give you years of energy efficient,
trouble-free use operating at 12 or 24 VDC, mounted close to the ceiling or
installed with the 16" down rod (or use 1/2" plastic conduit). The Vari-Cyclone can be powered from a
battery bank or directly from a PV panel. The classic white body and blades
will fit almost any dιcor.
Use in residential or commercial.
Ratings: when mounted at least 8' above floor in
open room. 3-blade, on 12 volt is 60 rpm/2500 CFM, and on 24 volt is 120
rpm/3400 CFM. The 4-blade will move even more air. At 12 volt it is 53 rpm
with 3000 CFM and at 24 volt it is 110 rpm with 4100 CFM. The airfoil
blade shape will not move much air if fan is ran in reverse. Made by
RCH.
Stainless steel fan hardware for higher corrosive climates such as coastal
areas.

DC Evaporative Air Coolers
Solar Chill
12 or 24 volt DC
Special Order 48 volts DC, 120, 240 Volts AC |
|
The Solar Chill
evaporative cooler's housing is made of stainless steel. The
efficient 6" thick wetted pad can last 5 years. The 24
has the best air flow and pressure and is be the best for use with ducts. Ducts
are not recommended but if used they should be short and oversized. 1 year warranty by manufacturer.
The 24 and 42" models ships by truck freight collect. The first 2 numbers of model
are Fan Diameter, second 2 numbers are voltage. Output diameter is 3/4" larger
than blade diameter. Max GPH is the maximum Gallons of water used Per
Hour.
Units can be powered by solar electric module direct but it
is normally best to run from a battery.
Sizing units: In a dry climate, use about 3 CFM
(cubic feet per minute of air moved) per square foot of space to be cooled if normally insulated with not much
solar gain. It will take more to cool a space that is poorly insulated or has
many windows on east or west sides, such as trailers or RVs. About 8000 BTU's of
cooling is produced for each gallon of water evaporated. Rates can vary from 1
to 7 gallons per hour.
Water Pumps: Water is pumped
from a reservoir to the filter and evaporation media and drains back to the
reservoir. The optional clean-out pump and timer are available to empty
reservoir daily. This reduces mineral and dirt buildup and increase media life.
The circulation pump and clean-out pump are the same pump and may be used
interchangeably. For automatic water cleanout use pump on a timer.
The optional control package with thermostat will improve cooling performance
and reduce humidity buildup by automatically turning cooler on and off as
needed.

Wall mounted control box contains a thermostat, a two speed (HI/LOW)fan
switch, a pump switch, and a timer for the cleanout pump. Set the
thermostat and go to sleep without worrying about wasting energy or getting
too cold. Run just the fan at night to conserve energy and water or just
the pump for a few minutes to get the pad wet before firing up the cooler.
The cleanout timer runs a pump that will flush out all the water and harmful
minerals from your cooler for five minutes which extends the life of the
pump, pads, and cooler box. |

Pump Control
Timer Board,
extends pump life, higher efficiency cooling 2 lbs
$60 Pump control
timer board is an electronic circuit board mounted to the back of the
electrical cover plate. This board can be added to any of our 12, 24 or 48
volt coolers as an upgrade and is now installed standard on all new coolers
in all voltages! What does it do? The pump board has 2 main functions: to
lower the output air temperature, and to increase the efficiency of the
cooler by decreasing the amount of energy used, and increasing the life of
the pump by decreasing the duty cycle. The pump board has a built in timer
that turns the pump on for two minutes and off for three. How does this
decrease the temperature of the cooler output air? Since there is not a
steady flow of water passing over the pad at all times the water held in the
pad has a chance to get colder than it would if it was flowing over the pad
consistently. With evaporative cooling as the pad gets colder the
output air also gets colder. The pump board also lowers the amount of
energy used since the pump is "on" for less than half the time, and it
will as extend the life of the pump. |

The Fresh Air Cooling System
Evaporative
cooling uses a system of air flow called the Fresh Air
System. In this system, fresh outside air is brought in through
the cooler, where it is cooled and pushed through the building,
then exhausted to the outside through screened windows or doors. This type
of air circulation differs from traditional air conditioning, which uses recirculated
air, allowing the same inside air to revolve over and over again through the
building, and unlike the the Fresh Air System, works best if it is sealed
off from all outside air leakages and exchange. This causes stale and
toxic air in your home or office! These problems are known as "sick
building syndrome".
The Fresh Air Cooling System, used by all evaporative
coolers, is beneficial as compared to the re-circulation of the AC
units, because evaporative coolers are designed to supply an entire
exchange of all the buildings air every 2 to 3 minutes. Evaporative cooling
greatly reduces environmental air-impurities; while AC units will continue
to re-use the same polluted air, often causing problems with indoor air
quality.
For for this system to work well, the windows must be partially opened to
allow air to escape, which allows the freshly cooled air to enter. If
the windows are closed, the exhaust and intake air will be restricted, and
the building will become pressurized and not cool well. The intake of fresh
cooled air will be blocked.
Through the use of the SOLAR CHILLtm
Evaporative Coolers, the diagram shows how the cooling system works without
the use of duct work. It is preferable to eliminate the ductwork
and use the building as the ductwork instead. This is more energy
efficient by reducing the friction to air flow that ductwork
causes, and saves you the cost of the ducts!
