- I install an evaporative cooler AC unit to keep the shop cool this summer.
Swamp Cooler, Evaporative Cooler, Desert Cooler, and a few other names that these go by.
This is the cooler I use in the video: amzn.to/2qlDOo6
I really like the slim design and it really seams to beat the heat. As you probably already know evaporative coolers aren't for everywhere. They cool to right around 10F above your wetbulb temp(look it up on a weather app) which is entirely dependent on your humidity. The lower the humidity the better these work. The run for a fraction the price of a compressor AC system and double as a fan in my shop to clear fumes quickly.
For my Australian friends they sell this there as well: www.bonaire.com...
As far as locations that can benefit from an Evaporative cooler, there are many. Here is a map www.sylvane.co...
Here is a chart as to what you can expect cooling wise depending on your humidity and outside temp

*Great and Easy to instal **Fastly.Cool** Low noisy*
Wow that is amazing
1. Bright sunlight 84°F
2. Dark No sunlight 68°F at NIGHT.
that little switch is amazing, turning daytime into nighttime.
That little switch controls the Universe.
I used to see cars in dry climates with what looked like a chunk of stovepipe attached to the side window which worked on the same principle to air condition your auto. Man that was a long time ago but the principle still worked great and still does today.
Thanks for the video Moe. Always enjoyable.
EdOfTheNorth It's a rarity but you can still find those units. You pretty much had to fill them before every trip.
i believe Packard automobile co. pioneered this principled type of early auto ac, I have the written packard ac description sheet describing the unit .
Just installed one of these in my home, replacing the old style unit we had been using. With temps in the low 90's, inside temp at back room was in 70's. I love it.
Sam Keller It's great to be cool.
Your going to love working in the shop even more. I lived in El Paso for two years and they worked great, hardly any cost at all.
***** It has been amazing the last few days.
Here in central Colorado these work fantastically. You do need to vent by opening a window in the opposite end of the home, because this is cooling by pushing massive cooler air volume through, and not recirculating as with AC. We prop open an attic access hatch, and the cooler, moisture-rich air goes across the house attic space out a gable vent above the swamp cooler. It might be a risk for mold etc. in wetter climes, but here with attic temps way above 120 F there is no chance for moisture buildup. Run the unit either manually or with timer, from mid to late pm until bedtime when night temps typically drop below 70. Basic maintenance = clean each spring (still on first pads after 7+ years), disconnect and drain in fall, stuff insulation bags into fan and cover inside for winter. 1/10 the cost of central AC, less KWh, some cheap water consumption.
z1522 get yourself some new pads.
I had two of those roof models when I lived in Arizona. July and August were the only time they weren't very good as there was higher humidity those months. They take a bit more maintenance but they are much cheaper on your electric bill. If you need cool quick, you can spray the pads with a garden hose. I like the model you installed. Light weight and with a window model, easy to block off in winter.
57WillysCJ Yeah, they work good in here in Utah. There are generally only 1-2 weeks in the summer that they don't work very well on the temps in the home rise to around 75 during the day. The cheapness in me makes me keep it and the tinkerer in me loves to maintain them.
Hey 65, thanks. When I was down in Texas, I stayed in a house w/ one of them.
In NJ, years ago, there was a small factory stuck so far up in the woods, I never knew it was there. They made gauges and meters for the government. Years later, I was talking to a former fire chief and he told me that the brook that was in the back of his house was actually a huge drain for all the "sweat air conditioners" that were in that factory. Otherwise, that brook would be bone dry most of the year. I used to fish in that brook back in the 60`s and never knew it. That water was pure enough to drink and so were the fish clean enough to eat!
1fanger Really neat.
In 'southern Australia' here and yes I can confirm how effective this system is, I am going to make one for my truck because of how little power they use from my batteries so I can run it literally 24/7 through summer if I want to.
I just installed one of these for a neighbor and they love it. we will be installing one in our home as well.. shop has an oldschool roof mount (40 yrs old)
DillysADV It's a great addition.
Great video! Are you concerned about the moisture in your garage though?
Good idea about framing in the AC. Thanks Moe.
Robb's Homemade Life Hey Thanks..
That is a Neat unit I wonder how cold it would get if you added some dry ice to the water ?? ..When I was a kid my uncle had an under the dash air conditioner thing in his 66 Ford pickup It held about a bag full of ice but it only lasted about 50 miles on a hot day
not2fast4u2c I have actually done quit a few tests on temp. If you put any ice in and lower the temp of the water to around 35F, the air temp blowing out will be cooler but it melts the ice FAST.
Swamp coolers are great. One important piece to having them be effective is they must exchange air in the house so cracking windows open on the opposite side of the house makes a huge difference.
I had designed an low-voltage thermostat adapter for mine when I lived out west (late 90's)...the circuit used relays and connected to a standard mercury thermostat, it would run the pump for 30 seconds before turning the fan on so it never blew hot air through the house. I could probably find the schematics if anybody is interested.
Dennis Joslin Very neat. I would love to see a schematic.
Great video! Never seen a swamp cooler like this one. Now I want one
Thanks for the video man! Great stuff, but here in So. Carolina we have enough humidity already. LOL! BUT, just as a side note, Industrial sites around here use large cooling towers, (swamp coolers) but then use conventional AC systems to remove the humidity. It works fine so, maybe that's an option home shops too, but not as efficient as yours obviously. All the best, Charlie
PS: I really appreciate the content you post for us. Always entertaining and very useful info. HUGE Thumbs Up for your channel!!
Charlie Zellner Thank you very much. I've heard of units similar to what you describe.
The cooling towers are usually used to cool the water that flows around the condensers of large systems, so the towers indirectly cool the building by removing the heat from the refrigerant after it has gone through the compressor.
The thing on evaporative cooling is to vent the area to keep humidity down. That's the biggest mistake most do when using one.
Exactly. The air must move THROUGH the building and exit so that the moisture laden air coming in behind can finish the process of turning that liquid water into a vapor, absorbing heat as it does so, then carry that heat back outside. If the air flow is stopped or slowed the water vapor will change back into a liquid, making your building warm and very humid.
AKA Wireguy I don't think you quite get it when the water evaporates it absorbs heat that is a refrigeration effect and it does raise the humidity but if you live in Albuquerque New Mexico beautiful thing to have a swamp cooler is is like a cooling tower for a chiller and that application as the water evaporate it cools the liquid water and it goes back to the condenser Barrel cool the refrigerant it condenses to a liquid and back to the evaporator we developed that technology in 1912 you can only use these and dry climate in Florida no way but during the summer when it's 95 degrees they really work well in a garage
Larry Fries for
A dehumidifier would increase the room temp. They give off a lot of heat to create the cold temps on the tubes to cause the moisture to condense. Not worth it.
Swamp coolers were really common in the South (Oklahoma/Texas) when I lived there. However, they work best in dry climates. In humid areas they are worthless.
Good vid as always Moe. I wish I could use one of these in NJ where I am. But the idea of how you framed it in was a good one. That I can use.
Thanks for sharing
- Jack
Fireship1 Thanks, Jack.
Fixed a leaking pan/pool, roof mounted one years ago. Stopped a hot tar roofer working up the street. Six packed (+$20.) him into mopping the pan before his tar pot cooled on his way home. So CA. Worked well 19 hours a day. Used AC 1:00 to about 5:00 PM in August.
MYFREECAMPER Awesome deal.
Thanks 65, I have a 2.5 HP 2 stroke outboard motor I got that was frozen after running and taking a dip in Salt water. I found it was just the 2 main barrings that needed a bath in WD40 for a few days. But I busted a head bolt.
can not get the stud out.....had a small engine repair guy walk a drill around it and bugger it up another good weld guy attempted to weld to it....no luck. about ground down the Alum around it and weld to the old bold....may shoot and post a video of it. Any suggestions would be great ! :') Thanks
I would weld a stud to it and use a bolt to hold that part of the head on. The other head bolts would still be bolts that go down into the cylinder.
That's what I am going to do I am thinking......got the stud with a nut at Napa yesterday. Just need to grind a bit of ALUM down to get to weld it. Rally like your videos thanks ! I am also very frugal and see the value in old and broken stuff. Hope to make a video out of this project and begin posting some more.
I was considering getting one but did not know how it worked. Thanks for the video.
The lower the humidity in your area the better they function. There are maps showing how well they work in your area.
That's awesome, I like it! I think I could feel the cold air way up here! lol
***** I don't think it ever gets warm that far north.... Thank Man.
I worked in the oil patch in west Texas many years ago and the homes out there have scampers. They worked great but here in Louisiana the humidity level is far to high. I sure like how energy efficient they are.
BCtruck, rebuild, repair,repurpose Yeah, West Texas is a good place for them..
This might be a good idea for cooling during the hot summer nor west winds we have here in Christchurch NZ. Not commonly used here so good to learn about this domestic version and the low power requirement. Would be interested to learn how much these units cost.
Once again another very informative video thanks, well done.
elcianz This unit was $500 but they have less expensive and more expensive. They work best when humidity is below 50%.
I actually installed one of those exact units in a friend's house about a month or so ago, Dropped their cooling bill from $300 a month to about $75.
sgfreak37 That's great. Here in Utah there's only 1 week generally where the temps are above/at 100F so that's the only time the home temps stay at around 73-75F which is a little uncomfortable. Other than that The units seam to do fine keeping the home at 70F.
sixtyfiveford I lived in Utah for two years, Clearfield to be exact. The weather there is so much better than where I live now. The Antelope Valley here in California gets in the triple digits most of the summer. And I must say, Swamp coolers are better than nothing, but they don't do much when it is 110 outside.
very cool I bet that does work great!!!
2LateIWon It's been amazing the last few days.
Love the idea of a swamp cooler...unfortunately, here in upstate ny...our humidity makes it feel like a sauna outside for most of the summer.
Yeah, that's a deal killer.
That is awesome and installed properly.
Yeah, time to put this away now. I miss it in the winter as it is such an amazing way to exhaust fumes out of the garage.
I live in MD. You have no idea how jealous I am of this.
Peter Lerkaram I don't know how you put up with humidity. I guess you get used to it.
sixtyfiveford Lots and lots of air conditioning.
Pretty cool! I've never seen anything like this. Though, I have heard of a "swamp cooler" to keep fermenting beer a little cooler by using a tub of water and wrapping the fermenter in a towel that also sits in the water and wicks it up, and turning a fan on.
Tim Sheets Yeah, it's the same principle.
Here in iraq we are using this type of air conditioner since the 50's..
Here in the southern part of America you'd be breathing in a moist hot sponge with one of these.
I envy and adore you all at the same time
My grandparents had a swamp cooler it was great saw this model are lowes today $600 if you want keep electric bill down great idea
Your right in a dry climate these things should work great. But, in Dallas Texas you have to add ice to these things. Or the humidity will literally kill you. And once your ice melts and the water cools down. Back to sweating we go. And I mean sweating!!!!
***** Yeah, Dallas is too humid. They use these a lot in Western Texas though where the "wet bulb" levels are a lot lower.
JC Whitney used to sell these for RV's. Might be a good solution for boondockers. Cool video.
+middyband I haven't looked through a JC Whitney catalog for some time... I can't count how many hours I spent perusing the pages.
That brings back memories. I used to spend hours\days reading the catalog even if I had nothing to buy. Now I remember what I did before the internet.......I browsed countless catalogs. I love technology but I miss the old days.
JC Whitney was actually Warshawsky's on Chicago's south side. I've been there a few times.
middyband
Just googled it and see they used to have Warshawsky catalogs and they look identical.
yeah, they were only Warshawsky's catalog was free. I don't if the store still exists or it is just mail order.
I just put one of those up on my house.It had one of the old type on the roof,but it's so rusted it didn't work well anymore.The cost of having a new one put up on the roof was way too high,so I bought one of those and put it in a window myself.It's great up to about 100,but not when it gets to 105.It still keeps it livable,but not great.Still a good compromise for cooling vs cost.My utility bill goes way down in the summer.
M Poole I'm really hoping the plastic on this doesn't get brittle in the sun and just fall apart. Metal=rust and plastic=cracks.
It is supposed to be uv resistant.I've seen metal ones rusting within one year.Plus mine is on the west side of the house so it's shaded most of the day.
sixtyfiveford Put an awning on it to protect it from the sun.
What is the brand and model number? Where can you purchase it from?
I made an Ice Cooler AC once for just one room. Worked great! I used 2 liter pop bottles for ice worked all day. Then, swaped them out and used them in the master bedroom again worked great all night. Cost zero the cooler was given to us and the fan I already had.
It's a Mastercool mcp44 that I got from Lowes last year. I was going to lean a piece of plywood up against it to block the suns rays.
Great video. Me being from Tucson AZ Swamp Coolers suck in the Monsoon Season here lol That is an Interesting Swamp Cooler!
TRX450R Vlogger Yeah, it's the most modern/high tech looking swamp cooler I've ever seen.
Nice vid. I may actually add this to my garage. No windows though so I'll actually have to do some cutting and framing to make it work. Never lived with a swamp cooler before, but have had friends that have them. Don't think I'd want one for my house, but should be good enough for my garage. Especially since it would just be occasional use.
glendayle It definitely makes a garage nice.
Another good tip, love your work Buddy.
Julius Caesar Thanks..
I did not see a drain tube being installed. The pump should have a smaller hose outlet to reject some of the pumped water into the drain. This is very important. With no constant drain, your evaporative pad will have a lot of mineral build-up. This is a common mistake that causes quick and premature cooler failure.
neat set up
drvshaft drew Hey Thanks. It'll make it a lot more pleasant to work outside this summer.
They will not work in East Texas where the humidity is 96% all the time. Do you have dirt dobber wasp? Those things would clog that thing in a heartbeat.
Very cool!! (Pun intended), I wish I could use this method in Michigan.
Gerald Thomas Hey Thanks. I would be nice if the had a cheap cooling device for the more humid areas of the US like this.
I am here in Melbourne Australia and they work great but they are useless in places like Sydney and Brisbane due to high humidity.
+David Goldfish Yeah, if you live where can take advantage of cheap Air conditioning it's a good thing. Thanks Mate.
68 degrees in the garage,hell I would fall asleep,and never get a thing done!! How much does one like that one cost?
FJ80Coop Crazy government gave it to me for free.... The local power company is trying to milk government kickbacks in an effort to be eco friendly with low energy use devices. Since this uses significantly less energy than a conventional AC unit, they offered a $500 rebate for low energy AC units and Lowes charge me $500+$40 tax for this one. So All I ended up paying is $40 bucks or so in sales tax but essentially it was free.
Sweet,nothing "cooler" than essentially free...When I lived in Az. I had a swamp cooler on the roof,and those things really work well for no more complicated than they are,and since I had done hvac,boiler,chiller work for a decade,or so by then it really got my attention for simplicity,and how well it worked along with the cheap power bill compared to an equivalent ac unit...
Hello 😁 I'm thinking about buying this model used and I'm wondering how's it holding up for you. Also, do you think this unit will cool 900 sq ft or should I stick with the big metal ones? Thanks for the info.
I have a brand new one of these for sale
@@Youtubsucks5 and you live where? Also, I'm guessing it didn't work for you then?
Live in the North Phoenix area I cleared out a storage unit and got four brand new ones still in the box
Best garage mod ever.
The Curious Noob Hey Thanks..
Very interesting, Question: will this make your garage humid?
That would be great for my shed, I have a brook 100 feet away.
***** They only make it 5-10% more humid. The rule of thumb is they cool to 10F above your current "dew point"
cool. literally and figuratively
Ozzstar Haha.. Thanks man.
There's a big difference between a swamp cooler and an air conditioner, which would be that the former adds humidity while the latter removes it.
+Fire In The Sky Yes, but they are both classified as an air conditioner and both, depending on region, will cool the air.
Yup, I had no idea these things existed - I was wondering why all the A/C units in Utah were on the roof and now I know why - they aren't your typical A/C unit - no swamp cooler here - the humidity is on average 60% and a lot of the times it's 80+ - we wouldn't want to add anymore moisture to the room
iWatch It Yeah they really won't do much in 60% humidity and high heat. They would only drop the temp by 5-10 degrees in those conditions.
Nice install Moe ! Thumbs up man ..
It won't be 68 on a hot day, it will be more like 80-85 deg. It can only get a close to the wet bulb so it won't be that cold. If you want cold get ductless air conditioning.
Vaughn's Trailing Depends on where you live. 100 yesterday and I had it down to 70 no problem. A 10,000btu Ductless AC wouldn't be able to keep up with a poorly insulated garage and would struggle to keep it at 85.
cool dude! In Minnesota it's 'ha- ha' cold feet in winter or cool room in summer.
What make an model is that . That's the coolest thing I've ever seen.
I have a link in the video description.
If you live in a dry climate, an evaporative AC unit should work just fine. With 5%-10% humidity, you can achieve about a 25 degree temperature differential from 100 degree (F) outside air and 75 degree (F) inside air. However, once you start approaching 20% or higher humidity levels, the temperature differential is less because the water inside the unit is not absorbing as much heat from the air. Refer to a psychometric chart for temperature differentials at different levels humidity.
If you live in a humid climate like that found in East Texas, Georgia, Mississippi, etc, you'll be throwing your money away buying an evaporative AC unit since it will not be effective.
An evaporative AC uses about 1/6 the energy of refrigerated AC unit.
To size unit, you want an air change about every two minutes. You'll need to calculate the volume of the space to be conditioned (L x W x H). Example: room is 20' x 20' x 10' = 4000 cu feet. A 2000 cfm evaporative cooler would condition the room adequately (4000 cu ft / 2000 cu ft min) = 2 minutes.
Very cool, I'll definitely look at getting one! How often do you have to replace those cooling pads and how much do they cost? Thanks
The pad replacement interval really depends on how "hard" your water is. Eventually it will get plugged up with minerals and stop absorbing moisture. There are chemicals you can add to break these down and get more life out of the pads but generally you can expect a few seasons out of them. The pre cut pads they sell are under $50 but you can put in bulk generic pad for $10-20.
WHAT WAS YOUR MESERMENTS FOR THE HOLE IN WALL
Nice adition!
cutworm59 Thanks man.
I never heard of this type of AC either. Very interesting. Do you need to add insecticide to the water so mosquitoes don't breed inside them?
I learned that the newer conventional window units don't have a water drain hole for condensation to run out. The fan splashes the water onto the aluminum fins and compressor to make it work better but some parts inside are steel and they rust. It takes a lot of juice to run them and the electric bill goes sky high.
Dasdfjkl The water cycles out so fast that mosquitoes can't breed in it. Also they really can't get in unless they crawl through the mesh.
+sixtyfiveford
yea, I love mine - I use a portacool one - works really great
www.flickr.com/photos/davisglenn/19699743880/in/dateposted-public/
Now you can say you have a coooooool garage :-D
Nice simple system, very little to go wrong :-)
zx8401ztv Thanks Mate.
That's a great unit! I have two of the Bonaire Durango 5900 cfm units. One of them running on medium will keep my 1500 sf two story home around 77 degrees when it's 108 degrees outside as long as the humidity is low. At night it will freeze you out! Las Vegas has the lowest average humidity in the country so it works great. My power bill has went from $280ish down to $80 by using one of these evaportive coolers and switching over to LED lights. You are going to LOVE that thing! Nice clean install. Where do you live? Around Cedar City or St. George?
vegasfordguy It has been amazing in the garage. Yeah, I've used one for my home forever and love the low power bill. I'm up by Salt Lake so it really never gets over 100 and we have the very low humidity as well. These will keep my house at 73-75 on a 100 degree day and it cycles on and off at lower temps. I just bought a thermostat this year for the home one and love it (worth the $50)
Never heard of this thing before. Why won't it work in wetter climates? Too much moisture? Another great video 65FORD!!! WOOOOOOO!!!!! LOL.
Love2boat92 Yeah, too much moisture. They add humidity to the air to cool it. If the air already has a lot of humidity it can't add any and just works like a fan.
sixtyfiveford Oh very interesting. I live in a warm wet climate so this wouldn't work. Thanks!
Any chance of you building a lawnmower lift table? I can't get down on my knees to change belts etc. On my riding mower. I'd love to see your take on this idea.
Joseph Chase I have had this on my to do list for quit some time. Just last week I cheated and found a high lift pallet jack for 20bucks. I threw a board on it and I have a 2200lb capacity lift table. You can see me using in my newest video ruclips.net/video/nc_hPu6CHvo/видео.html
Thanks. Moe great video.
Cool Bruce
Bruce Pender Thanks Bruce.
yup arizona thats what you used change pads every summer winter put a cover over it low maintence
Here in Utah their pretty common. The simplicity makes them economical.
Good video Moe nice job
Alan Mulry Hey Thanks..
Did all your tools start rusting?
If it's water that is used to cool the air before its circulated, why does it have to be installed in a typically dry environment? I live in Florida and my garage gets ridiculously hot, so this would make life so much better for me, but we have a rainy season.. Why does that matter?
+Dave Talbot Just like sweat cools you by evaporating off your skin, basically the water needs to evaporate out of the air to cool it. If there is too much humidity in the air the water can't evaporate and the cooling effect is lost. It will cool 10F below whatever your " wet bulb " is (look it up with your current weather).
Nice,love it. Now I want 1 after watching this video. What type of cooler is that. 👍🤘
nice swamp cooler. What's that called and where is the best place to get it :) I've never seen one. I have the common type & it gets gummed up and not even worth it. I just blow the cool air at night then button up during the day. Not cool when it doesn't cool down at night.
tblbaby They don't work great in humid areas. The general rule of thumb is they will cool 10F above your dew point. Today it was 85F outside and we had a dew point of 54F. So my evaporative cooler can get it down to 64F, which is great. In a humid enviroment you can see dew points in the 70"s so it's performance suffers.
Isn't that much added humidity bad for a garage? Seems like things would want to rust.
These only add maybe 10% humidity. So when you only have and average of 10-20% to begin with there is no concern.
great video. how do those swamp s work compared to the traditional ones? and do you have a moisture issue in the garage as the monsoon season hits?
They don't work in high humidity areas of the world.
I think I'd get more accomplished with an AC in the Garage. Thanks for the video. North Carolina is not a place for swamp coolers, though.
RyeOnHam Yeah, I think humidity is the last thing you need more of.
Can you vent into the attic or is that a bad idea? I live in Las Vegas so it’s dry
Looks good man nice!
It's made for a very enjoyable shop.
Not to pick nits but a swamp cooler is not a true air conditioner. An air conditioner not only cools, but removes humidity from the air. A swamp cooler ADDS moisture to the air. Great in dry climates like west Texas, New Mexico, Arizona. Terrible in the gulf coast region.
It cools the air and uses very little electricity, win win. But yes it only works in places with lower humidity (low wet bulb temps) which is essentially the entire Western US up through Canada, continent of Australia, North Africa, Europe, etc. Approx half the world can and do take advantage of these.
Sir what's the price for this & from where we can buy this please reply
Sure could use one here In my garage but, as you mentioned, the very high humidity of 70-90% in this part of NC, wouldn't help much. I did install an attic fan high on the exterior garage wall and it helps. But when the outside temp is high it doesn't help to pull that through again, arggg! Wish there was another way to cool my garage. Only option seems to be an actual small A/C, which aren't too expensive but the electric bills would be. Any idea how these might work in LA, California? Brother in law needs something? Re the ice car: if you could just get some tools in there (haha). Hope you had a nice barbecue or picnic.
MRrwmac I wasn't in LA itself, but spent some time in LA county, (Lancaster/Palmdale area) and most of the houses use swamp coolers, so provided the climate's the same/similar... it'd work in LA
***** The easiest way to determine how well one will work is look at the "dew point" on the weather. An evaporative cooler will make a home 10F warmer than the dew point. It looks like LA, CA has a dew point the next few days of just under 60F. So it should make the home 70F.
So how do you keep dangerous mold and mildew from growing inside the constantly humid environment? Seems like you would be blowing in the spores.
Mold isn't remotely an issue. These are used in low humidity areas of the world.
sixtyfiveford Theres water in the trey, I'd be pretty sure there is humidity being added
sixtyfiveford hi I live in Escondido California in summer the temperature is 85 between 95 and is good in this area?
It works good in Phoenix 👍
Neat System!!!!!!!!!!!!
Robert
Robert Fern Hey Thanks, it's been great the last few days.
Slimline swamp cooler is in the market for last three years in Central California, and I even saw it over Costco about $399 but do it work in temperature over 105??
In a really dry climate (below 10% humidity) you should be able to see approx 75F house temps at 105F outside. The more humidity the worse it does (20% humidity @ 105F will give you 81F inside)
Here's a chart
www.alloutcool.com/image-files/xevaporative-cooler-chart458x298.gif.pagespeed.ic.-hqVI60D9C.png
Man I wish that would work in fl but our air is already swampy.
scottsinfl Yeah, last thing you want is more moisture in the air.
From experience, on hot days 90-100 the water inside the unit gets so warm it no longer cools any more than just blowing straight air without the water flowing.
The water temp inside the unit plays almost no role in cooling. It all about the water evaporating. The most basic example is the 98.6 water that you sweat and it still cools you. The lower the humidity the more evaporation and better the cooling. Today it was 96F and this cooler was blowing 60-63F air with a humidity of 20%.
sixtyfiveford
Our water cooler never has blown air that cool except maybe when the outside temps was under 75*. And it never blew air cooler than around 10* cooler than outside temps.
And that's why i use an a/c system now.
have you measured the indoor humidity compared to outdoor before and after the swamp cooler runs? My indoor is right at 40% right now at 2:51AM indoor temp is 75, my 8000BTU window unit that is vented into (it's installed through the wall) in the shop area where temps hit 100 or more during the day. The temp outside is 77, humidity is 91%
You won't get cooled if you have 91% humidity. On a 100F 91% humid day it would blow 80F air which is 20F cooler, but 80F air won't feel good. They work great for low humidity areas which encompass about 50% of the US. Here's a map of the idea regions www.lumacomfort.com/blog/does-evaporative-cooler-work/
Hi, do you have any rust problems on your tools from the moisture
These are only for low humidity regions. Rust is not a concern.
sixtyfiveford thanks, was concerned about rust on table saw
Legionnaires breeding ground for sure. They work great, nurseries use them too.
The water is never misted into the cooling room so it wouldn't carry Legionnaires Disease. The water is evaporated into the air increasing the humidity a little. Evaporation wouldn't carry Legionnaires the same as you won't get Legionnaires from being around and breathing the evaporation of a body of water containing the bacteria.
sixtyfiveford Do you know how it got its name? Swamp coolers, bodies of water, etc are perfect breeding grounds for the bacteria that causes it. How do you think the people that it was named after got it?
Now that you've had this for a year, what are the pros and cons with this unit? Thanks!
I wouldn't be without it. You do need to live in a low humidity area to take advantage of an Evaporative Cooler though.
+sixtyfiveford I am.. I just want to make sure there are no big negatives to this unit. It seems to be the only (well reviewed) window unit that pushes out enough to cover around 1500-1900 sq/ft.
I like the plastic as it seams it will hold up better than the steel(rust) long term and it looks very modern. I didn't have room on the side of my garage for a full size square window unit as I park my RV/boat there. It does use these strange 2" thick cardboard pads that are expensive(supposedly highly efficient). But when the time comes I'll just swap in the blue mesh ones I really like.
Great video but no good for me in Queensland Australia our humidity can get up 85℅ plus in summer, u have a shower and straight the sweat pissing out of u.
+Graham Bate That's a lot of humidity. I know that the dryer areas of Australia use these a lot.
yea they do, back in the last 80s company try to put up here in Queensland, but don't work that well here. it not 85% all the time, but we can a lot summer storm
We had one in the house in SE Kansas, it caused a lot of mold, and damaged the furniture.
John Barleycorn They really don't add more than 2-5% more humidity to the air, so I'm very surprise by this. A very dirty and improperly stored/cleaned one could hold mold in the unit but I can't imagine it making the mold spores stick to other items unless windows weren't opened to create airflow that is required for these to work. In that scenario you could increase the humidity dramatically.
You spent over $600 on that ? The link to Amazon says they are priced in that range.
Actually because it is super energy efficient the power company had federal rebates on it(kind of like solar panels, led bulbs and other garbage). I think it was $500ish from Lowes with a $500ish power company rebate. So I had to just pony up for the local sales tax. But I would buy one again even at $500. You can get cheaper used units that are all metal/typical swamp cooler style, but they stick out several feet from the wall and need far more bracing. They are large and heavy, so that is why they're more on Amazon. It has to cost over $100 to ship this so they have to roll in the fake free shipping to appease customers.
I used one of these in my garage and man it made it humid as fuck!
Only if you don't know how to use one. It needs a constant air flow out through an opposing door or window. It will only raise humidity maybe 5-10% above ambient humidity which is negligible. So if your at 20% humidity it may take it up to 21-22%. If you close all your doors and windows and crank this thing up it wont cool and then it will put the room full of humid air.
let me tell you how this works when the water is sprayed into the media the water evaporates and cools the air by evaporation that's in a refrigeration effect
NO DETAILS OF INSTALLATION?
Nice vid, always fun and informative. I live in the Northeast and it will not work here.
59chevt Yeah, not so lucky. Thanks
I hate swamp coolers, a refrigerated window unit would be so much better
Why?
wow. 6 yrs ago but bud i hope whatever it is that pipe does its been raised above that cooler! that looks dangerous as hell!
I like that unit how much was it looks kinda like my portacool
Wes Shaw Crazy energy companies want to get government rebates so they make consumer incentives for low energy devices. Last year it was $500 with a $500 rebate. I just had to pay sales tax but other than that it was free.
Mighty garage mods
its_ tristan ;-)
hi @sixtyfiveford do you recommend this swamp cooler for a city with high humidity like 90%?
That's a lot of humidity. It wouldn't do much good with that much humidity.
sixtyfiveford thank you so much!
Its very difficult to do evaporative cooling in humid climate, high humid outdoor air and indoor air will ruin it
what is the cost of this coling system
What is the humidity level once you get to temperature?
phooesnax Generally around 10% more than outside.
