No space heater - it's Thailand. Thanks for the other info. I'm going to stick to my functionality test which is much easier. If I can keep the treadmill room between 20-23c and humidity rarely crossing 60%, I'm a happy man. I'll still be sweaty but with a fan also it will be comfortably warm. The amount of water extracted by the AC would be interesting. I already built a funnel from where it come out to the Infront of my sliding glass doors so I can verify the system is working. It's is a quite amazing the amount that is running across the patio. Once the flow stops, I know that in 10 minutes the room will become miserably hot and muggy. I like numbers so next hot day (won't have to wait long ) I'll do that and my bet is 2 liters an hour. Cheers

Well this thread has gone off the rails but a few posters answered my OP. Gamma as usual does his own thing which is entertaining. Easy to skim Gamma's long rambles. In the end I think I found the solution. In summary my refrigerant was tested during the professional clean a few days ago. Not the issue - LOL. This has happened for 20 years in my exercise rooms. This new room was just built and the AC installed 3 days ago. It is almost able to do the job and depending on the day usually takes well over an hour at running at 18c to ice over. All the erroneous posts ( trying to help 🙂 ) got me thinking. I knew the AC was not the issue but many ( mostly one) were telling me otherwise. So I did some experimenting yesterday and I think I have the solution. As Gamma stated he can run his AC at 21c continuously 24/7 (as I can on my other non exercise room ACs) and I can't run mine ( 4 different ACs) while exercising "very" hard for 90 minutes without issue. To some the solution is probably obvious but wasn't for me. Do the normal thing as Gamma does ( normal and gamma in the same sentence 🙂 ) and run my AC continuously and not just an hour before starting my treadmill run and turning off after. Did this yesterday and zero issues. The area where I run was a steady 20.5c +-1c and the humidity went from 48% to 59% in an hour. It never topped 60%. The coils were dry at the end of my session. To keep it at 18c (humidity ~100%) you'll need near perfect airflow across the evap coil to prevent condensate from freezing. Even at 20c it will freeze over most days. If I left it on for 12 hours at 20c I doubt there would be an issue but I only use the room for a couple hours a day at most. I think I could get away with setting it to 21c a few hours before and raising to 22c during the treadmill run but a rare cold front is moving through and can't test it. Thanks everyone

Yes, it works fine after it thaws as my previous 4 ACs in my exercise rooms over the last 20 years. All had adequate refrigerant. Not trying to be rude but nobody seems to have read the OP. I don't need AC advice but asking about how to lessen the humidity.

Perfect and thanks!!! I think I'll go with the Xiaomi because my AC should remove at least as much water. I'm "guessing" the AC can almost do the job without the dehumidifier and if I can remove an extra .5 to 1 liter with the dehumidifier per hour the coils won't ice over.

It is funny at this point. This happens with every AC for 20 years and doesn't happen with the 15 other ACs not used in the my exercise rooms over the last 20 years. I find many of Gamma's posts entertaining and his posts above are no exception. Now I just have to buy a dehumidifier. I sweat about 2-3 liters an hour on very hard days and dehumidifier would theoretically capture 1 liter an hour and hope the AC can drain another 1-2 liters. If I started at 45% humidity and the it climbed to 75% that would probably be OK and the the coils wouldn't ice over.

OK, you are correct. Thanks so much 🙂

Interesting and for my small 3x4 exercise room it would be much cheaper I think. I have done a little research and 5k-8k baht unit should suffice. It won't be running more than 2-4 hours a day. My current AC can drop the humidity to 45% in a couple hours and creates a river by the drain pipe. I'm going to see if it is able to keep the humidity down in dry mode while on a long treadmill run in a few days. Running outside today 🙂 My prior ACs wouldn't cool much in dry mode but this new AC does and the humidity drops fast. I assume it is because it it is oversized for the tiny room. Thanks for the input.

Yes but it doesn't apply to my situation which I am 100% sure is caused by humidity when it nears 100% for 90 minutes. I wasn't asking about my AC functionality. I have owned probably 20 ACs over the years here in Thailand and understand all the issues you discussed. I had my 3 ACs cleaned 5 days ago and a new AC installed the same day. My AC iced over in the AC that was just cleaned. I then moved my treadmill to my new exercise room and it was frigid during my easy workouts but iced over after 90 minute hard run just like all ACs have done over the last 20 years in Thailand. BTW, all the non exercise room AC are working perfectly as they always have for 20years - LOL. It would be almost impossible for any AC under 12000 BTU( A 20k + BTU would remove the humidity faster than it could accumulate in my 3x4 room ) to not freeze up often when the windows are fogging over as they do occasionally during hard 90 minute runs. Thanks for trying to help but yet again it isn't answering my question in the OP. Cheers and thanks again 🙂

Is this the weird story you've created in your head that completely ignores reality?

This new AC's dry mode is behaving different than the previous AC. It actually drops the humidity and the temp! Only used for 30 minutes tonight while on the treadmill. 23c and 45% humidity which is almost ideal. Maybe I don't need a dehumidifier 🙂

Wouldn't like to be them. Every week having to find new content and in the end it is hopeless. There are a few authentic YouTubers but most are chasing clicks. Bumped into a pair of exercise enthusiasts Youtubers at a race and felt sorry for them. They weren't enjoying the experience and were trying to profit from it. I guess there are worse gigs but...

Yep, and destroy the treadmill and virtual bike setup in a month because of water damage.

Actually not a bad idea if I had a 24000 btu AC in the 3x4 room. Then again if I had put in a 24000 btu AC the coils would never freeze over because it would be able to dehumidify while cooling with the windows closed.

Has zero to do with my situation. Read my OP. This happens with split AC when humidity nears 100% which it did today before freezing up as did my four prior ACs. Google will confirm what I know if you have doubts 🙂 Nobody has answered my OP - lol. No problem and this is entertaining. @Crossy did have some good ideas that do delay the freeze.

Nobody is reading my posts 🙂 It is the humidity and this is common occurrence. The AC is a few days old and this has happened on 4 previous ACs. The humidity is nearly 100% after 1 hour running hard on the treadmill water sometimes runs down the windows. This happens with split ACs and I was asking if dehumidifiers might work.

Had those issues also but not the reason for my AC freezing over. The same problem as the prior 4 - extreme humidity.

Yes, that does make a difference. Most the time it eliminates the freeze but occasionally my longer runs still cause the coils to freeze over as they did today. Thanks and any exerience with dehumidifiers?

Been down this route the last 20 years. It is because the extreme humidity causes the coils to freeze. It happens all the time in "extreme" humidity. I was curious if anyone had info on dehumidifiers.

Yes, been here 20 years and used many ACs. It is the humidity and looking at a solution to drop the humidity because any AC I buy will freeze over. Hmm, I once had a 21000 btu in a small room and the ac didn't freeze over so that is why I brought up buying a second unit. My treadmill workout are hard and sweaty.

Just put 4 days ago and worked perfectly. This has happened with 4 ACs and only the exercise room. I know 100% it is the moisture. My workouts are extremely hard. Just trying to figure out how to reduce the humidity. Thanks for the input.

This has happened in 3 different homes and it only happens in my exercise room. I sweat more than anybody I've ever seen while exercising hard. My new( installed 4 days ago ) 1200 btu AC in a small exercise room measuring 3x4 meters and had issues today. The indoor coils behind the air filter were frozen which was the issue in my other homes also. Would a a dehumidifier reduce the humidity significantly? If so, any recommendations? Maybe a second AC unit?

Never seen a Chinese but have seen westerners <deleted> themselves and defecate in public while in Thailand. Below is one of many examples of how the westerners make the Chinese look like saints. https://www.ndtv.com/lifestyle/viral-at-thailands-full-moon-party-beach-tourists-get-a-literal-sea-of-poop-7314591 Hey but if you need to feel better insulting Chinese then have at it. Doubt they care much about losers opinions 🙂

This thread is going nowhere as all "new Thai tax threads". It has been anything but interesting... Adios!

I agree and how some are confused is beyond my understanding. I think it is the DTA that trips them up but not sure. Will they go after future earning in private pensions? Maybe...

Your guess is as good as anyone's. Is Thailand going to get a forensic tax unit to analyze what portion of 2024 saving are based on cost basis. I seriously doubt it and hence the pre 2024 exemption. In the future theoretically earning realized or unrealized will be taxable.
