Natatorium Knowledge
США
Добавлен 6 апр 2020
This channel covers topics related to indoor swimming pools, which are also called Natatoriums. In particular, we focus on the indoor air quality of natatoriums, and how to improve it. Bad air quality is caused by chlorine byproducts like chloramines that off-gas from the water and create the "pool smell" we are all familiar with. But that smell is a symptom of bigger problems that can ruin facilities the indoor swimming experience for people.
Our mission is to fix and prevent such indoor air quality problems in natatoriums across the world. This channel covers any and all topics related to indoor swimming pools, indoor pool air quality, chloramines, pool chemistry and pool equipment, pool operations and best practices, etc. On the air side, we answer HVAC and pool dehumidification questions, mechanical designs, and architecture. We help architects, engineers, contractors and pool owners fix and prevent natatorium air quality problems.

Types of Swimming Pool Filters (w/ Justin Caron)
Commercial swimming pools have several different types of filters. In this video, we interview Justin Caron, principal of Aquatic Design Group, and he explains the differences between the filters. As a pool designer, he's an expert on filtration and has seen what works and doesn't work in countless pools around the country.
There are basically three types of pool filters: Sand filters, Cartridge Filters, and D.E. Filters. But in commercial pools, it's dominated by two types: sand and D.E. And these D.E. filters are not a typical residential DE filter with grids; they are regenerative DE filters, which are advanced technology, with beautiful water clarity.

Do NOT blow air directly on a swimming pool | Supply Airflow in Natatoriums (w/Keith Coursin)
Просмотров 3,7 тыс.2 года назад
Indoor pool air quality problems stem from airborne chloramines off-gassing from the pool. Your first thought might be to flush the chloramines off the surface with supply air, but that's a BAD idea. Keith Coursin, President of Desert Aire (desert-aire.com) joins us to explain the consequences of aiming supply airflow directly onto the water surface. Evaporation rates increase, and chloramines ...

Vapor Pressure in Indoor Pools (w/ Keith Coursin, Desert Aire)
Просмотров 4402 года назад
Vapor pressure is an aspect of humidity. It is an important factor to consider when designing an indoor swimming pool natatorium. Keith Coursin, President of Desert Aire, joins us to explain vapor pressure and how it behaves in pools. Key takeaways: - vapor barriers normally go on the outside of a building to prevent moisture pushing in; but for indoor pools, the vapor barrier needs to be on th...

This is the first time I've ever heard someone say that they're confused by different 3-point lines.
wouldn't having an April Aire 130 dehumidifier and a simple ac good enough?
Long Bridge Aquatics and Fitness Center is an example of a missed opportunity. The original plans were scrapped and only half of what they wanted was built.
It was really wonderfull conversation..More conversation similar to this are needed. Thanks
Thanks for this vid man, great info
Thank you so much. This video gonna help the generations
dehumidification is a very expensive process. i can imagine an alternative system that, instead of using a huge dehumidifier, exhausts the pool air outside and replaces it with low-humidity air from outside. the incoming air would have to be heated in the winter, but maybe you could get some of that heat by recovering it from the outgoing air with a big heat exchanger or something. why is dehumidification used instead of a system like this?
Indeed dehumidification can be expensive; it uses a lot of energy. What you're imagining is frequently done in low humidity areas, but it does not work in most climates because the humidity differential is too much to manage a consistent RH level. Everything needs to be maintained in equilibrium, and outside air varies too much for that to be the only solution. The good news is, good pool dehumidifiers can sense the humidity of the outside air and they adjust accordingly, so when the humidity outside is low, these systems take that into account and energy is saved.
1:30 the simplest way I always explain it to customers is the pool is a pot of constantly boiling water
It does depend on the age and manufacture of the dehumidifier. Since 2010 most systems are allowing a 4 inch MERV 13 filter to be installed. The filter racks are adjustable. If it is older than that, then you may not be able to put anything greater than a MERV 8 filter (2 inch).
I'm a maintenance supervisor of a 400+ resident property. New to the natatorium. I'm used to horror for the last 5 yrs. Can someone please tell me the recommended MERV rating on air filters for the dehu system. Is it 13?? Or higher? Thanks in advance
Thanks for highly educational content . Since pool room should be always under negative pressure ,please give us some information about exhaust fan and make up air .
You're correct. The pool room (natatorium) should be ~10% negative relative to adjacent spaces (bathrooms/lockerrooms, lobby, hallways, etc.). This requires selecting the right type of doors and windows to seal air properly, and having a pool dehumidifier that controls the pressure in the space. The pool dehumidifier (PDU) controls the negative pressure in the space by regulating how much exhaust air and outside air move through the space. I hope this helps! If not, email us at info@chloramineconsulting.com.
Great info. Thanks.
These videos are great ... thank you so much ... but one of you guys need to change your smoke alarm battery.
Yes, Steve's smoke alarm was beeping. And unfortunately we couldn't edit it out because it was always when he was speaking...
I'm consulting for a client in the Denver area with a natatorium. Do you have any contacts for engineers or HVACD contractors in the area who can do moisture load calculations and size equipment solutions?
Hi Mark. Yes. Email us at info@chloramineconsulting.com and we can put you in touch with someone.
Planning a separate 2 story swim spa building for my family. Very interesting and informative series, thank you
I have Seresco dehumidifier need to replace High Side pressure transducer and crank case heater for compressor does i have to Pull vacuum down on refrigerant line I get quote from tech guy for $5k
Ideally how big a land should a true olympic pool be? An acre?
An acre could be enough, but you'd need to factor in deck space, equipment, access, etc. It would be safer to have more like 1.5 or 2 acres.
Blah blah blah. I was hoping for more pictures or deep the water is. Next
Official Olympic pools are 2 meters deep. As for more pictures, video editing is not our forte. Clearly.
@@natatoriumknowledge9392 If video editing is not your forte then good luck on your channel!
what makes a pool fast? thin water.
Thin water is a good answer, we like that. We'll go with that.
Thank you for the knowledge ! Much appreciated
And what if your indoor pool in on the Mendocino north coast where is is cool temps and you use a drinkable pool system where I'm not using any chemicals?
Why not just have operable skylights.
What the expert think about dehumidifier vs recuperators? I am heavily leaning for the air recuperator coz of constant delivery of fresh air and removing the chlor(amines). But so far I cannot find suitably small quality recuperator, while the dehumidifiers comes in all shapes and sizes.
From Keith: "An air recuperator is also known as a push-pull air handler with energy recovery. This system will only solve the humidity issue when the outside air conditions are lower than the design conditions and therefore is rarely used. There are only a few year round climates in the USA that this will work. Many hours the humidity and temperature outside is higher than inside the pool room and cannot provide conditioning. The other issue is that even with energy recovery, this system will actually have higher energy costs because dehumidifiers have two internal energy recovery elements (for the air and the pool water) that are significantly more efficient than an air to air recuperator. The use of low exhaust on larger active pool rooms has been very successful in mitigating the off gassing of the chemicals. In residential or small hotel pools, insuring the system is introducing code ventilation is sufficient." Hope this helps!
Very informative - thanks
Glad you enjoyed it!
Best explanation ever. Thank you
Glad it was helpful. Thanks for watching!
Thanks for the education. This will really help me out on a 1948 indoor pool project.
Great to hear. 1948?? It's rare to see natatoriums that old...very cool. Let us know if you need further help with the project. I'm sure we can learn a lot too. info@chloramineconsulting.com.
Thank you for this excellent and highly informative content!
Glad it was helpful!
Imagine me if i was there "oh no I regret doing this im out of breath that fast oh man i dont wanna die god pls deliver me from dying oh lord i call upon your name to deliver the water hurt my nose"
So how deep is the water
at least 2 metres deep
