portable evaporative cooler (swamp cooler) - used portable swamp coolers

In areas with low humidity, ordinary air conditioners do not work very well.
A simpler solution is to use water evaporation to cool and wet the air.
These are called evaporation coolers or swamp coolers, used in homes in the southwestern United StatesS.
The fan pulls the air to the wet pad and the wet pad reduces the air temperature by 20-
30 degrees also provides much needed humidity.
We took part for a week.
In the remote Nevada desert, the temperature is above 100 degrees Fahrenheit during the day.
In this case, it must be completely "out of the grid", self-control and self-reliance.
To stay comfortable, we built portable swamp coolers with ordinary materials powered by solar panels to cool down our enclosed living space.
They are also used for more permanent greenhouse cooling facilities.
In addition, they can also provide temperature adjustment for desert families without electricity supply. 36-

If you are patient and resourceful, a lot of things are available for free.
First of all, you need to make way for the air to pass through the wet liner: Cut 2.
There are 5 inch diameter holes on the side of the trash can.
The drill bit used to cut the door handle hole works very well.
Keep 10 inch of the garbage can intact with no holes.
Padded x two layers with a blue evaporation cooler line up inside the trash can.
Put it in place with a hardware cloth or chicken wire inside.
Keep up with U-
Bolts drilled through the side of the trash can.
Now you have a trash can with ventilation holes lined with evaporation cooler mats that are kept in place with hardware cloth wires.
Now you make a dropper to keep the padding moist: make a circle with an irrigation pipe with a diameter of 1/2;
Add a 1/2 T-piece.
Drill a very small hole every 2 inch m or so at the bottom of the circle for dripping water. (
If you want to become very fond of it, you can insert the drip irrigation device into the hole, which will give you a known gal/hourly drip irrigation rate. )
Now we need to get the water to the top of the mat: Place a 12 volt submersible pump at the bottom of the trash can.
Connect the pump to the drip ring with a 1/2 pipe.
Deliver the wire through one of the holes so that you can connect to the battery power supply at the next time, we need a fan at the top that sucks in the air through the holes on the side of the trash can, pad through the evaporation cooler and enter the HVAC pipe from the top, which will provide coolness and humidify the air to the position you choose: Cut a circle at the top of the lid of the trash can and install the fan.
Make sure it blows up!
The old car radiator fan was cheap and blew a lot of air but used a lot of amplifiers.
So we ended up buying a solar.
A fan of about $200 runs forever on a 45-watt solar panel connected to a deep cycle 12 volt battery.
The car radiator fan will use more juice than this system outputs, and will only run for about 20 hours before running out of the battery faster than the solar panel charge.
However, if you have enough solar panels, the car fan does release a lot of cold air compared to the breeze from just Solartype fan. Wire it up!
It is a good idea to weld the connections, but you may want to make the wires of the top cover/fan/HVAC pipe assembly unplugged so that they can be removed for easy shipping and packaging.
I also installed a switch to cut off the pump on a cool morning and only need a fan.
It's too cold!
The whole unit needs to sit in the collecting basin and collect the water coming out of the side (
This kind of dripping water is inevitable).
The large black bathtub in the center of the garden works well.
You may need to drill holes in the bottom of the trash can to let the water penetrate back inside the pump.
The first photo shows that the finished body has no top.
The next three views are looking down at the cooler, showing the pump and dropper.
Next is the top view of the fan installed.
Then, put together the view of the whole thing and use one of the views.
No solar panels were seen.
You need about 6 gallons to fill it up and get the mat wet.
After that, use about 2 gallons/hour depending on humidity and temperature.
More holes in the drip ring may lead to more water use.
This is why the discharge device may help reduce water use.
For home/permanent use, install a toilet float valve connected to a permanently pressurized water source.
Campers are called Flip
Pac, above the truck cab is where to sleep.
The swamp cooler HVAC pipe points to our sleeping area.

Keep the deep cycle charge of the 12 V battery.
The battery provides consistent current for the swamp cooler pump and fan.
By the way, the green structure behind the truck is our beautiful shower.
