To all of you over heated truckers out there.
I have the answer for your situation and that of many truckers in North
America. What is now happening in America has been law in Europe for a
number of years now. In Europe, you are no longer allowed to idle your
truck at all during rest periods. You can imagine how hot it gets in a cab
in spain, Italy or the south of France in the summer. A company in Holland
developed a dc air conditioner with a low battery draw and a high output of
BTU's for cooling truck cabs and sleepers, RV's and compact tractor cabs.
Check out our web site at www.dcairco.com
My name is Ron March - Vice president G.O. Power Inc. located in British
Columbia Canada. G.O. Power Inc. represents Transolar in North America. The
high quality Sunny AIRCO 1300 and 2000 DC voltage air conditioners are
manufactured by Transolar in Holland and has been very popular in Europe in
the RV, trucking and heavy equipment industry. We are in the start up phase
of distributing Transolar products in Canada and the U.S.
The real benefit of the Sunny Airco is that it requires no hoses or belts
off the engine to run the compressor. All the power to run the unit is
taken from the battery, 12V or 24V. The unique design of the Sunny Airco
provides for a low battery drain and a high output of BTU's. You can cool
the truck camper unit or small RV while driving or when the engine is turned
off. The Sunny Airco does not rely on ac hook ups. You can park off road,
away from RV parks with ac hook ups and still enjoy a comfortable
environment.
The Sunny Airco looks like any other ac roof top air conditioner. The
installation is simple. You will need to cut a hole in the roof to mount the
unit and run three leads down to the battery. The battery can be the normal
12 volt vehicle battery or an auxiliary deep cycle battery, charged from the
vehicle engine when running. The Sunny Airco has a low voltage (adjustable)
cut off switch to prevent a discharged battery. The thermostat and controls
are in the inside of the cabin, for easy access.
The two models currently available are:
Sunny Airco 1300 Sunny Airco 2000
Cooling: 1300 watt 4420 btu/h Cooling: 2000 watt 6800 btu/h
Under development with production scheduled for 4th qtr. 2002
Sunny Airco 3000 Cooling: 3000 watt 10000 btu/h
We are working with a company in Canada who supply compact cabs for
tractors, lawn mowers, back hoes etc. They supply these cabs to tractor
manufacturers in the U.S. such as Ford, John Deere, Massey, Toro and Kubota,
as well as others They are going to redesign the roof of the cabs to
incorporate our DC AIRCO's
We are also working with two large truck manufacturers, who are evaluating
our Sunny Airco's with the idea of providing DC air conditioning for their
truck sleeper cabs. In many States in the U.S., laws are being introduced
to prevent the idling of truck engines when parked, to cut down on air and
noise pollution. These trucking manufacturers contacted us because of the
success we have had with DAF trucks in Europe.
In addition to the roof top model, we are working on a wall mount unit which
can be mounted on the rear of a sleeper cab or hidden in the engine
compartment of a large RV or Bus. This unit could be used (connected to the
same ducting as the AC air conditioner), when the RV or Bus is parked, but
there is no access to AC power. This will be a heavy duty metal cabinet
designed to handle heavy use in a trucking, bus or RV environment. We are
using a similar unit to air condition heavy equipment tractor cabs in
Europe. These units will provide for 4,000, 10,230 or 17000 BTU's.
I am providing a rough dealer price list for your perusal. This is based on
the purchase of single units. Units purchased in quantities would be
negotiated within a contractual agreement.

The RM1300 consumes 25 A/h maximum on 12 volts. We advise therefore a
battery capacity of no less than
100 Amp hour. 12,5 A/h with 24 volt. The RM2000 consumes 36A/h on 12 volts
and the 24 volt version 18
A/h. For this unit we recommomend a battery capacity no less than 160Ah.
Because of the low energy consumption of the Sunny Airco, when the vehicle
is connected
to the mains the RM1300 will only draw 1.5 Amps per hour respectively 1,9Ah
for the
RM2000. This is ideal when on a campsite that has only a low amp connection.
When
using the Sunny Airco on the main please use a battery charger that is at
least 25A for the
RM1300 and 40A for the RM2000. It is also possible to run the Sunny Airco in
conjunction
with solar panels. If a 2 m² surface panel is used then there will be enough
energy to
provide extra running hours.

I didn't see where he posted anything about watts. I would be interested in such
a beast, though.

If I connect the unit directly to my truck's battery system, how long before
the batteries are drained uesless?
As most truckers will tell you, even a 40qt cooler will drain batteries dead
in only a few hours.

Rooftop Airco's
The Sunny Airco 1300 and 2000 are roof assembly units for Trailers, Trucks
and Remote Vehicle愀.
The most important advantages are:
- Sunny Airco's do not need a generator
- Sunny Airco's are cooling whether you are driving or not
- Sunny Airco's are equiped with a battery monitor/low voltage disconnect
For example: a truck can run it all night with 2 x 200Ah batteries.

Ok, let's do the math. 2 batteries 200 AH each = 400 Amp Hours
****************************************
450 Watts devided by 12 volts = 38 Amps
****************************************
You still need to start your truck so we will use 300 AH instead of 400
AH . 300 AH devided by 38 amps = 8 Hours run time.
****************************************
Next problem is the 4420 BTU. The average truck has a ac unit that
delivers over 2 tons or 40,000 BTU. Will only 4,420 BTU be enough
cooling? If the berthing compartment is properly insulated and sealed
off from the rest of the cab you should be ok. If it has to remove
solar heat coming in the windows and windshield along with engine
heat , No WAY!
*****************************************
You can obtain the same results with a home window AC and a DC to
AC inverter.

If you have what you say you have, then it will be a big hit in the U.S., and it
is exactly what I have been looking for....as long as the prices are in line
with what you quote....
I'm keeping this one on tap for the future...
Thanks for popping in to let us know about your product...

It would be better to have one or two batteries that are isolated from the main
batteries, so that they are not discharged. Using deep cycle batteries would
also work much better with what he is offering. You can isolate them for use of
the unit, and switch them back over to connect with the main system, once you
have started your truck for the day to recharge the ones that the air
conditioner would run off of.

I have no idea where you get that idea from. 40,000 BTU?
Most homes with 2000 square feet do not have this much.
A simple window unit designed to run off of 120 VAC have around 5000 BTU.
These will cool a 14X14 room, with ease.

Ya, that's 36 amp hours per hour or to say it the correct way, simply,
36 amps of current flow. That means that after only 3 hours of use you
will have consumed a total of 108 Amp hours and only have 52 amp hours
in reserve to restart your truck. Now it is going to take another 3 to 6
hours of running the truck to fully recharge the 160 amp hour battery .

Wow a 2000 Watt AC unit that only consumes 450 watts. Do you also sell
125 gallon fuel tanks that will hold 700 gallons of fuel? Or how about a
truck that can go 300 miles in a single hour while keeping under the 65
MPH speed limit!

Yes most home central units run from from 1 1/2 ton (30,000 btu) to 5
Tons (100,000 BTU). Cars and truck have very compact but vert powerful
units (1 to 3 Tons) needed to overcome engine heat and high solar gain.
Also a home unit draws air from from inside the home. ( the inside air
handler ,not the out side condenceing unit.) For safety reasons a car or
truck must cool out side air (fresh air) . It takes 8 times more energy
to cool 90 degree air at 80% humidity than to cool 80 degree air at 50%
humidity. That is why you need such a large unit. I worked for a
computer company company for 26 years. Helping customers design computer
rooms was part of my job. Most computers rooms were less than a 100,000
square feet. A 3 ton unit would of done the job if there were no
equipmen to creat heat. For every 1200 watts of equiment you need to add
another ton. after adding hundreds of pieces to this room now you ended
up needing a 100 ton unit. It would be interesting to find out how they
really do it in Europe.

Simple answer to the power problems. Next time you're near a marine
store, stop in and check out what we boaters use.
Here's what we do with marine setups for overnight dockage with no
power hookups - and trust me here - if your boat battery goes
dead.....well that could hurt.
You're going to run three batteries in your truck. One is for engine
starting ONLY. Two are going to be deep cycle marine batteries. Your
connection to your charging system is a black box (just a little
computer that figures out who needs the most charge) that starts your
engine from your starting battery, which is not designed to be
discharged very deeply. The black box will charge all three batteries,
giving priority to the starting battery. Now since you're probably
going to be charging your system for several hours, this would work
better than it does on a boat.
Now as far as power draw on a deep cycle marine battery goes. My
trolling motor will pull 5 amps average draw. With a fairly large
marine battery we get about 7 hours of use. Now if you have two
batteries, you're talking 14 hours.
Do a search for marine batteries on the web, the ratings and charging
requirments are different than for starting batteries. You can even
get these little gel batteries that weigh almost nothing - could run
half a dozen of them if needed.
