HVAC 166 Evaporative cooler how it works inside

Part 2 of evaporative cooling. How the evaporative cooler works on the inside covering the basic components and operation.

Louvers, pads, float valve, drain, overflow, water distribution, water treatment, pan coating, blower motor, pullies, bearings, rust, setup and overall operation.

This does not include the new models but the basic operation is the same. The new models have a linger lasting hard type cells for evaporation and more compact direct drive motors, and composite wheels that doesn't rust.

I really like the amount of explanation you give Mr. TY. Personally I enjoy your teaching the most but so will say HVACR videos, HVAC School, AC Service Tech LLC and Anti DIY HVAC are all great people. Thanks for making these videos because I’ve learned that people get tired of explaining the same stuff over and over and your videos with others provide super valuable knowledge that can be learned without the stress of asking a person to repeat something.

Awesome! The narrative that you present on this video is outstanding for beginners, thank you so much…

[GreenAppelPie]

Thanks!, I gotta fire one up for the season and now I know what I’m looking at.

Very helpful breakdown of medium scale equipment! I'm working at a combined cycle power plant that has evap coolers for the air inlet of the gas engines for efficiency gains, and I've only ever had a surface level understanding of the concept. Where I'm living, I'm surrounded by data centers that are all hiring for operating and maintaining UPS systems and various cooling solutions. This video looks like it addresses what an evap cooler in that setting might look like and, more importantly, what problems and solutions to expect and implement in the field! Most other video results were about small scale swamp coolers for a room, which is the same process, but not very helpful to what I wanted to see.
Thanks for the hard work and good teaching!

Exceptional explanation and very thorough!

I like the second pump system the best. Basically, it is a blow down method, been used in steam boilers for many, many years. The cooling towers where I work has a sand filter system where accumulated mineral deposits can be removed through a blow down. We use a chemical free method of controlling mineral deposits.

I worked in Las Vegas for 30+ years maintaining Evap coolers as part of HVACR service and without bleed off or pump down those coolers would scale up within months. I liked using Coolpad vs. aspen pad. Mastercool celdek coolers were the best for providing the coolest air.

Awesome! First time I hear about these units, then again I'm pretty young in the trade...
Very good explanation, hopefully I never have to work around these units, but incase I do, I now have a better understanding of them..thanks ty...👍

I live in Colorado, I love my swamp cooler! Best $500 I've ever spent! I have only had to replace a pump and a couple of belts. My home is 920 sqft and it cools the whole house down!

Thanks for doing this demonstration with a rusty system because its more realistic. I learned a lot and I really like evaporative coolers for dry environments, man it feels good, and I like that its an evolution of ancient wisdom and technology. I wonder if newer evap cooler systems have a better protected motor because my evaporative cooler gets absolutely blasted with the evaporated water and when it dries that calcium cakes it up. I probably just need new soaker panels haha, once a season and Im over here reusing it for several seasons, thats probably my main problem.

Very informative. I just bought a house with one. Thank you.

[GamezManolo]

Thanks I just bough house with this old unit and it looks bad.thank you Mr.TY

[passangsherpa]

Thank you so much for all the videos and explanations! This dirty blower wheel can we pull and clean out or there is no way?

[vidademikey]

I run em till the wheels fall off. Its still good.

[carlschmiedeke]

They need to make the whole thing out of stainless steel, I am going to build 1 outta stainless steel

What do you think about the Eco pump Have you ever seen it Check it out

[HVACRTECH-]

Seems to me putting treatment in the pan is not going to do too much for these systems, I'm in new england, I've never seen one before but I'm experienced in water treatment for feed water systems and what's going on with fresh water being added daily to these systems is not going to be controlled by adding chemicals to the pan, especially on the ones that pump out like you say. The best thing would be to filter and run the water through a softener system before it feeds the unit, better yet an r o and a softener, then you could probly get 5 years or more out of your pads and 3 to 5 times the life out of the unit itself.

I have an evaporator cooler that is spitting/ sputtering out water from the supply air. The float is working correctly and isn't flooding/ doesn't have water near the blower housing. Any idea what is causing it?

[SpectreOZ]

We have a similar roof system but it's constructed with plastic (lower section) and stainless steel (upper section and panels), seems like the colorbond steel construction is a poor choice for the consumer.

[JohnSmith-U]

After watching this video...I will never buy or use a swamp cooler
