Thanks, don't take this as an insult, the above post is similar to Gamma minus 500 words.

Have a couple friends that lie with abandon and they are usually the life of every party. Weird, they lie so much that we just accept it as part of the show. They aren't mean and well intentioned. They just want to laugh and have fun. Only time it gets uncomfortable is when you become part of lie while everyone is in tears laughing at something that never happened.

I agree. He seems to have lived a miserable life. Just because he was famous doesn't imply he was happy. If he died content then just another example of a world that isn't fair.

Yes, I checked it out on shopee and it had good reviews. Power isn't an issue since I have enough solar to run the AC for hours before to bring down the RH to 45-50 RH. Takes a few hours and I can't set the the temp too low or it will freeze over during the run. I think the reason for this is the dry mode process usually maintains the temp or slightly increases it on most ACs but this TLC AC lets me drop the temp to 16. The dry process increases the moisture on the coils and at a low temp they freeze. Funny, I thought I could get around that by using the fan only for 10 minutes after the using the dry mode. The coils did dry but it blew all the moisture back into the room 😞 Appreciate the advice and the humidifier recommendation. Your arguments with Gamma were also entertaining. I am going to tinker with AC I have and see if it as simple as turning it on a few hours before I jump on the treadmill and not setting at below 20c. Last two days this has worked perfectly. My shoes were dry today after a 90 minute run which is rare 🙂

It isn't that you won't be found out because that is all too easy for me 99% of the time. It is that you might be found out and it doesn't add to the quality of a person you are nor improve the odds of living a satisfactory life. It is very rare for me to lie. Not something I'm proud of and somehow convince myself it is the best alternative. It probably isn't and I was just to lazy or weak to not lie. It is best to take the attitude that it is what it is and deal with it. I haven't lied to my woman in 4 years. I make a habit of not having to! Hard initially considering this is Thailand.

That was a lengthy read and I apologize for skimming through most of it and in the end I ended up not really understanding most of it 🙂 I'll try to answer your last question from my perspective. I need to remove roughly 2 liters an hour if I begin with a RH of 50 and I want it to below 60 while maintaining the temp of 22c. I sweat about 2 liters an hour running hard outside continuously. I very rarely run for an hour hard indoors because I break it up into intervals so 1 liter would be a good guess. E.g., today I did 5x3 mins with 2 minute rest at 95% effort followed by another roughly 30 minutes easy and ended with another 7 minutes at 85% effort. The RH steadily climbed during the 5x3 portion to 64% and steadily declined to 55 following the 5x3 and even declined further when doing the less hard 7 minute portion. After 90 minutes on the treadmill the RH was 52 which is close to perfection and the temp was 21c. I ran at the worst time which is around 12:30pm where the sun is shining directly on the rough. Today was cold so probably comparable to most days I start around 9am. My solution of letting the AC run for at least 3 hours before starting and not setting it to 18c but a more conservative 22c where liquid doesn't accumulate on the coils is working for now. Chrossy had a good idea in regards to using the dry mode but regretfully this caused the coils to freeze up quicker on 2 out of the three tests. If I ran in dry mode but increased the temp to 26 it would probably not freeze over but that is too hot. As Sometimewoodworker suggested, I will get around to picking up a dehumidifier. My bet is that this would solve the problem but with higher energy usage which isn't a concern because I have solar.

All good but not interested 🙂 If the AC keeps the room at the desired temp, then I'm cool. In this home over the the last 3 years I have had the treadmill in three different rooms with 3 different ACs. All three have frozen over and two of them did it often during the hot season. Also happened in previous homes and never in my non exercise rooms. I have enough data points for me but respect your opinion nonetheless. Take care

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 🙂
