Easy. Just give it a slap across the face. Yes. Oil Sands. Should have said oil sands. But too lazy to spell the extra word. Thought nobody would notice. Both dirty, however. And highly polluting to extract. Human Beings are complete and utter FOOLS. So...then...Die. Haha. We will probably all go due to Space Wars, anyway. Nukes in Space is not a good idea. Militarization of space is a worse idea. Humans will never learn, and this is what makes this species so dangerous. Once they have killed almost everything, and nothing much left to kill, then... They just begin killing themselves. Evolved this way, of course.

I was almost killed by a giant boulder on Mt. Rainier. I am still the man I was. But, I have given up mountain climbing.

If price of oil rises due to some cut-off of Canadian oil to the USA, then this will be a very good thing for America and the World. Let the Canadians keep their shale, which is the dirtiest among hydrocarbons. And, America needs to stop using Canada's oil...like... TOMORROW... Duh... Americans still don't understand this key point.

Fungible. I have been smoking "oil is fungible". Try some... Some time...

This is why I NEVER say anything critical about that NitWit XiJinPing. Someday, when he is booted out, I will want to return to China.

Is this a JOKE, or something? Water vapor from a very hot and humid climate like Thailand will condense on the floor, then? And then, you plan to actually walk on it without slipping and sliding around? And then, where does the condensate drain? This has GOT to be the craziest idea of the year.... No....the Century. As an added touch, not make the floors of that super slippery faux/real marble tile that is used in China. Very dangerous .

And now, Folks, I think it is time to address the, as yet unaddressed, part of this Topic, stated in the OP, that of ...Sweat. The OP, atpeace, states that he sweats more than average. However, is this really true? I think not. The OP clearly states that he sweats about "2-3 liters an hour on very hard days", and he seems to think that this means that he is some sort of... Super-Sweater. However, I disagree, and he is much mistaken. Obviously, the OP is not very familiar with Human Physiology, because if he were then he would know that.... Maximum sweat rates per hour, for an adult human, range from 2 to 4 liters. Therefore, just judging by the OP's own reporter, the OP is merely a middling sweater, and not... A super sweater. I have recently investigated the OP's contention and he is just plain average, at least... In the sweating department. There are many research articles which substantiate what I am stating, but the simplest blurb is that of... Wikipedia: So, also, if the OP is sweating only TWO liters per hour, then...we can probably guess that he is just.... Not working hard enough at his "hard day" workouts....because.... This would be my guess. And, just from my own experience, sweating....: When I was younger, I rowed a lot in the noonday Sun, both in Southern Florida, for fun, and in... Philly as part of a crew. This is how I know something about sweat. For example, when you get 8 guys in a shell, rowing up and down the river, for hours... The resultant sweat stays in the boat. And then, when you lift the boat over your heads, upon taking it out of the river....then... The gallons of sweat just pour all over everyone. And, most guys in crew do not wash their shirts and shorts, for weeks. This is true...and it's sort of like a tradition among all crews in Philly....and Just visit any boathouse on the Schuylkill River...because they all smell like... A zoo. So, anyway, this is what leads me to think that the OP might be some old guy, and not a young guy. Young guys sweat more than two liters per hour, EASY, during even a warm up, not to mention this... "hard day" the OP speaks about. But if you really want to know about sweat: Just try rowing an Alden shell in the Florida heat and humidity during summer months. After about 3 hours of steady rowing, then you are bound to have over two gallons of sweat... Sloshing around in the bottom of your boat. In fact, if you forget to bail it out, then there is always the danger of sinking in one of the alligator-infested swamps...which... They call canals in Naples. But they are swamps. So, the reason I mention this is that... Even though many of the statements written in this Topic see unbelievable....for sure.... The OP is not exaggerating when he states... Three liters per hour. =================== So what does this mean in terms of what might be required to compensate for all this sweat? Much of the sweat being sweated does not immediately evaporate. But even still, I would say that one should have planned for this, before one recently purchased an.... Air Conditioner. And so, I would say that if one plans to sweat 3 - 4 liters indoors, in a tiny room... First, please, choose an AC that is rated to remove about 4.1 liters per hour, of water vapor, just as does... The one that I chose, for my bedroom. I don't sweat much in my bedroom, these days. I am too old and celibate to sweat that much. However, if I knew that I were buying an AC for my personal tiny gym...then... I would first read the physiology research and plan for this sweating eventuality. =========================== I have already given this Topic a great deal of thought. As I said, I like this important topic. We can learn from others's mistakes, and this is how humanity progresses... Through passing down culture from one generation to the next, or from one TV member... To the next. ============================ Here are two things among many that I have learned from this Topic: a. Yes, adult humans can sweat up to about 4 liters per hour. b. My Panasonic AC can extract about 4.1 liters of water per hour. c. And, the machine I purchased is JUST marginal for use in a tiny personal gym. d. Yes, adding a fan will help cool the treadmill fanatic. e. But, in order to have a better workout, then do due diligence and choose a machine that will give you 55% humidity or below, at a temp of 23-degrees C, or below. When we are young, we can more easily tolerate temperature and humidity extremes. But when we grow old, we become desiccated organisms and we must make a Conscious effort to stay hydrated, day in and day out....which in turn...leads to... Less stress on our ACs. After reading this Topic, I will probably not be willing to buy an AC with a rating of less than 4.0 liters per hour. And, I am glad that the machines I purchased slightly exceed this minimum.

Have we not seen this....at least....once... Before? Theresienstadt

Trump does not need Canada. However, even the Canadians know, Canada needs Trump.

Totally correct. Nice to see an informed, and concise, comment here. Tks....AGAIN....!!!!!

This is a great Topic, since it involves problems with ACs in Thailand, and who does not love these? Here is what I would do if I were in the OP’s running shoes, faced with his dilemma. a. First, determine what is the optimal RH and room temp for evaporating sweat from human skin. (Meaning, the optimal ACHIEVABLE room conditions, given available equipment constraints.) b. It would be better to select a slightly higher room temperature and a lower RH. And this would cause sweat to evaporate faster from the skin. Higher temp: faster evaporation. Lower RH: faster evaporation. c. Personally, given my AC, I would try to keep the RH at about 55% or below. And room temp at 23-degrees C. This is, for me, the “sweet spot” affording fastest evaporation. c1. Also, at these levels of RH and temp, the dew point in the room will be under 13-degrees C, which is quite good for running. Do you not agree??? d. I would add a fan to the room directed at the man on the treadmill. This will evaporate sweat more quickly. And this would also compensate for the slightly higher room temp of 23. e. At 23-degrees C, the OP will create a lower RH than at 20-degrees C, for the same mass of water vapor in the room, and so sweat will evaporate more quickly. (obviously) f. Size of AC: As I have already noted, the OP has a VERY undersized AC for the size of the room, given his intended purpose for the room, which is, essentially, a private gym. THIS is just one of the problems causing the dilemma. The OP stated that the AC’s capacity is only 12,000 BTU. Is this adequate for the purpose? IMHO, no it is not. f1. I have stated previously that I use a 24,000 BTU unit which is rated at 4.1 Liters of water per hour, dehumidification, at a test temp and RH of about 28-degrees C, and 80%, as I recall. g. The OP has not, I think, yet stated the dehumidification rating of his machine, nor the model of his TLC AC. However, this should be checked before trying other solutions. h. IF he is actually evaporating 2-liters per hour of water vapor to the air, then a suitable machine should be installed which can easily compensate for this. Therefore, I would go with the machine that I purchased, or similar, which I have shown in one of my previous comments. i. To the question of using a dehumidifier: If adding a 700-watt dehumidifier to the exercise room, then this will produce a lot of heat. 700-watts of heat. Condensing water vapor to a liquid, as we all know, is an EXOTHERMIC reaction. This exothermic change and the energy required will ADD heat to the exercise room. How much heat? Well, just think of a 700-watt incandescent light bulb, is my guess. But I have not checked this, and the amount of heat added SHOULD be checked before purchasing a dehumidifier…maybe. (by the way, folks, an exothermic reaction releases heat to the surroundings, and in this case…the exercise room….!!!! So, maybe NOT such a good and logical idea, after all…right? Haha…because, one uses the AC for the purpose of cooling down the gym, and not heating it up…haha…!!! (smile)). I deeply regret that I will not have time to edit this comment before publishing because I am now very pressed for time…you see…I am in the midst of proofreading my PhD thesis on one very esoteric aspect of Thermodynamics. Still, I am confident that most of the information presented in this comment is accurate, or “fairly” accurate. And, a last final wish: I do hope that everyone here in this part of the world will enjoy the Cold Front now moving into this area, which the OP also mentioned in one of his good comments. Enjoy the cold, as much as you can, before the month of April, when it is bound to get Hot as Heck, as it always does in Thailand…during the months of April. Regards, Gamma Final Note: I would like to add a bit more info about some of the benefits of using a dehumidifier in conjunction with simultaneous use of an AC. There are good reasons for doing so, but only if the AC has sufficient cooling capacity, and if the outdoor temperature is lower than about 25-degrees C. (In the OP’s case, there is no excess cooling capacity of his AC which is sufficient to compensate for excess heat produced by a dehumidifier…IMHO.) So, Folks: Stay Hydrated, and keep your RH down in Thailand, too, during the impending Raining Season, which should hit us around June, this year, according to my calculations. Final Final Note: Kudos to the OP for such a great Topic, and for his sharing of his most sweaty exercise experiences....May all of us follow his lead...as we try to stay fit and full of vim.

VERY good point....!!! I think the Panasonic model which I showed earlier in this topic provides this function. Yes, and of course. This is why it is beneficial to select a brand and model of AC which is designed to work flawlessly in climate conditions typical of Thailand...maybe? AND....TKS!!! I consider this Topic to be rather important for most readers in Thailand, meaning just the general topic of ACs, and AC-usage failures and problems.

PhDs payback to society, to America, FAR more than we invest in them. If you do not understand how this works...then.... No further meaningful discussion can be possible. Of course, I prefer the Natural Sciences. And, even grad-research in medicine. If a grad student wants to be funded for pursing a PhD in lip-reading, then OK, I would not fund them. However, funding super-smart students towards helping them to pursue degrees which are so obviously beneficial to society as a whole.... One would be CRAZY to oppose such a concept. I know you are NOT crazy.... Correct?

In addition, I would like to offer up an informal EXPERIMENT that just might settle this question of... High room humidity as the prime causal factor leading to freezing of the evaporator coil: a. Will this happen on a decent machine, such as a Panasonic AC? b. Or, even with water vapor being added to the room, at a very high rate, will this NOT happen with a decent properly designed and operating AC? My test method will be to take TWO 1,800-watt water kettles, and open the lids, after filling them full. Then, I will plug them in, and let them rip. Both kettles, 1.5 liters each, should be able to boil off 2-liters of water in about 30 minutes, give or take a few minutes. This will DOUBLE the amount of water vapor being evaporated from the OP, during his strenuous exercise routine. The OP's exercise room is only slightly smaller than my bedroom, according to what the OP has reported here on this Topic. So then... IF I add TWICE the amount of water vapor to the room, in HALF the time, and set my Panasonic AC to....16-degrees C.... And, IF I keep the thermostat of the Panasonic machine set at 16-degrees C..... 1. Will the room temperature stay around 21-degrees C...even though I will be adding about 3000-watts of heat from 2-kettles to the room? 2. How will the RH change? 3. Will the Panasonic AC ice up? 4. Will I trip the CB? (no, this cannot happen with the electrical wiring, so no worries here) So, I figure this is the least I can do in the interest of furthering better understanding of what is really happening with the OP's TCL AC. This might take a day or two, to set up this trial...and so... Please stay tuned. And, hope this might help, in some small way. NOTE: This is a very interesting Topic, because, here in Thailand, who is not interested in ACs, AC failures, and AC brands....? NOTE2: Although I will be conducting this experiment in my bedroom, which is now quite well sealed and protected as much as possible from drafts from outside the room... meaning I will be boiling off the water in two water kettles...STILL...I have no intention of.... doing any WELDING in my bedroom.

So, YOU, say, Sir. But, I, for one, very much disagree....(haha, but serious, too).... Anyway, I would like to share with you an anecdote of an AC-problem time, back in 2001, just at the same time the NYC towers were hit, on 9/11. And, this is not a joke comment.... So what happened was, I tried to save money by buying a cheap AC for the bedroom of my house in Taipei, situated on one of the most exclusive mountain housing developments, HuaYuan XinCheng, fully of million dollar houses. a. I purchased a Samsung 9000BTU split-air wall unit, which was cheap as heck. A ridiculously- low price. b. I Turned it on, and used it for a few days. c. Although it was summer in Taiwan, and the weather was nothing out of the ordinary for that climate...the Samsung machine began to freeze up several times a day. d. I fiddled with the settings, to no avail. Ice, ice, and more ice, on the evaporator coil. e. I called Samsung in, and they checked it, but could not solve the icing problem. f. Long story short, I told Samsung Taiwan to take back their machine. g. I bought a Panasonic 12,000BTU unit for the same room. h. The Panasonic machine was heavenly. The temperature control, and the room temp variability on any given temp setting, was only about plus/minus 0.5-degrees C. i. Since that time, I have learned to always buy the best. For me, the best is Panasonic. I would buy a Hitachi, maybe, but I don't have any experience using this brand. j. Are machines supplied by Panasonic to the local market as good as Panasonic which were supplied to the Japan and Taiwan market 25 years ago? I will not say here. k. However, what I am saying is that I STILL believe, even though there are those here who completely deride my opinion, that the base cause of icing on your TCL machines is a problem with gas pressure being not right, as has already been mentioned many times. The problem is that the evaporator coil should never get down to 0-degrees C, or it will, inevitably, begin to ice up, no matter WHAT the room's RH might be. I know that readers here do not agree with me. However this is my experience. Also, with older machines, when they begin to lose gas pressure due to very slow leaks: a. They will freeze up. b. They will also freeze up even if the DRY-MODE is selected. I am only reporting what I know from experience. More importantly, I know just how frustrating and exasperating it can be when an AC ices up intermittently. And, for sure, you deserve to have an exercise room in which you can exercise in peace, WITHOUT being plagued by AC problems. What you need is to have a room where the RH is around 55% or lower, and where the temp is about 23-degrees C. If you can achieve these conditions, then water/sweat will evaporate more rapidly, and this will go a long way to giving you a better workout, without overheating. ============== Some of the installers here say the TCL machines are good. I would not know. I have never used one.

I have noticed that there seems to be a bit of confusion concerning: What volume of liquid water would need to be removed from room air in order to achieve any given drop in Relative Humidity, either at the same room temperature, or at two different temperatures. This is easy to calculate, of course. If I were to do this, then I would just calculate the mass of water vapor in the room, at 25-degrees C, and RH of whatever it might be, say 80% RH, the hypothetical starting point. Then I would subtract the mass of water vapor in the room, at 20-degrees C, and RH of 50%, the hypothetical desired RH and temperature. So then, given these conditions: Just what volume (minimum) of liquid water must be removed to achieve these results? Of course, this would be a minimum, since we can expect quite a bit of water vapor from outside the room to enter, continuously. Therefore: What would you say is the MINIMUM volume of liquid water which must be extracted in this scenario? Anyone wish to hazard an EDUCATED guess? This value is actually important to know, when selecting an AC. In addition: For some UNFATHOMABLE reason, especially in Thailand, it seems that sales people are underestimating the size and cooling capacity of ACs, for use in any given room volume. Why is this? IDK. However, in order to avoid such a calamity happening to YOU, then I would suggest buying ACs as I do. My bedroom, small I would say, has a volume of approximately 60 cubic meters, and if you also add in the bathroom, then probably around 65 cubic meters, give or take. Since I do not have much sun exposure, most of the time, and since the walls and ceiling is not well-insulated... I chose a 24,000BTU AC unit for this room. Was this a good choice? YES....!!! Why? Because I chose an inverter AC which is able to supply a range of (BTU) cooling, from about 7000BTU up to 24,000BTU, depending on conditions. And.... Also, since this is an inverter, the compressor will run almost continuously, which will provide excellent dehumidification during ALL 3 Seasons in Thailand. I realize that there are those on this Topic, and also on the Forum, who believe I don't know anything about ACs.... And, I do not blame them, because...so very often...I sound like a complete... FOOL. And, I like it like this. This is the way it should be... For me....IF... I really want to enjoy my life in Thailand. But still, when actually BUYING ACs here in Thailand, it is always best NOT to be perceived as a fool. And, also, one should not ACT the fool when making AC purchases, because... Bad results can be the result of one's folly. ================== Now, finally, let us please return to the simple absolute humidity calculation question that I posed above: This is important, and one should know how to estimate these values. Some here, obviously, have WAY underestimated the water vapor content of room air, and how much needs to be removed in order to end up with a more ... Comfortable living environment. And thus, I ask you: Can you provide the correct volume of water which must be removed in the above example? And, what is your preferred way to calculate this value? ======================= Before closing this single comment, I would like to wish everyone.... HAPPY HYDRATING, while exercising in this heat... Especially since we are now in the HOT Season, in Thailand.

Why don't you just HEAD FOR MIAMI, and find out for yourself? OR...even better.... Head for IMMOKALEE, FL.....

That's GOOD! Reason: I definitely IDENTIFY as Chinese even though I might be white, a roundeye, born in New England and raised just outside Philly, home of the CHEESESTEAK. So, I like to see Chinese produce great products. I fear that Japan is on the downhill, these days, especially in consumer appliance manufacture. I LIKE to buy Chinese products, especially if the Chinese products are not destined and designed for the cheap American Importers.

One reason for this RH difference, in all likelihood, is the temperature difference between inside and outside, if you keep your windows open. If windows are closed, then this difference might be due to the cold morning air in the house, gradually warming throughout the day, as the house heats up, And if the windows are shut, then the RH will decrease as the air inside the house increases in temperature.

Go ahead and laugh, then, if you will. But, you are still wrong, and I, Sir, am RIGHT! The above are the results for a 24,000BTU AC running for 15 minutes at HIGHEST Fan setting, and LOWEST Thermostat setting (16-degrees C). The bedroom room size is approximately 5 meters x 4 meters. No air leakage through windows which have been boarded up and sealed. (Of course, there is still leakage of air, to some degree, and this is why it is impossible to achieve 30% RH in-room, with an outdoor RH of 64%. It would be IMPOSSIBLE to reduce the in-room RH to 30%, given these conditions. The outdoor RH is just too high.... After all, my bedroom is neither a closed system, nor an isolated system. Did you think that I thought it might be????? How, ODD.) Note: Of course, I always use TWO XiaoMi Air Purifiers, running 24/7. Both purifiers are in the same bedroom. And, the readings on both machines are consistent with each other. This is the machine being used.

No it won't. There is much air leakage in any normal room. The AC, will continue to extract water from the air, during the full hour of the test. The purpose of the test is just to get some idea of approximately how much water is being extracted from the air over an hour period of time. Also, more than an hour will be required to extract enough water to reach an RH of 30%, which is something IMPOSSIBLE with an AC, if the outside RH is about 80, or so. And, before you are too hasty to reply, you have no evidence to show that what you have just stated is....TRUE. In fact, it is false, IMHO. How do I know? Because... I have the EVIDENCE....of course....!!!!

Of course, one more thing, and there is always "one more thing": You should turn-on your AC about 30 minutes before you intend to use the treadmill. Set the AC thermostat at the lowest setting (probably 16-degrees C) and highest fan speed. This will lower the room temperature as much as possible. Then, as you exercise, and as you say, the room temperature will rise. As the air temperature rises, the RH in the room will decrease, commensurately. I am sure you already know the relationship between air temperature and RH, but for those who don't here is the relationship.. The inverse relationship between RH and temp is... This is why it would be useful to cool the room down to lowest possible temp before exercising, and then let the temp rise which will dramatically lower the RH, even though it will not lower the absolute humidity....obviously.

Don't worry about the cold front, something that I am aware is now approaching, and here already, actually. Anyway, in fact, you CAN test during the cold front. All you need is a small space heater. Before you begin this test, measure the humidity in the room. a. Set the heater to about 1200 watts of heat, and place in your exercise room. b. Turn on your AC, and set the thermostat to 16-degrees C. c. This will cause your AC's compressor to begin operating continuously, and at FULL Power. d. IF your AC is functioning properly, and if the gas pressures are as stipulated by the manufacturer...then.... This will cause your AC to immediately begin condensing the water vapor in the exercise room. e. If you want to check the output of your AC (how much water is being removed per hour), then just go outside and put a container under the drain pipe from the evaporator. You should place the container under the outlet of the drain pipe (hose) from the evaporator at the time that your AC is switched on. And, you should measure the amount of water which drains from the hose for the FIRST full hour. f. Next, after the first hour has elapsed and you have measured the amount of water which has condensed, then record the humidity, and turn off the heater. f. Don't turn off the AC, yet...of course. g. Wait, and after the room temperature returns to about 20-degrees C, then record the humidity, once again. g. Turn off AC....if you want...It's OK, now... Yes, I am the RAMBLER, as you say. The Stones even wrote a great song about me,... When I met them, back in the day. Crucial and IMPORTANT Note to ensure success of this test: IF you sweat as much as you say you do, which I very much DOUBT, then, please, for mercy's sake, DO NOT exercise on your treadmill during this test, which would compromise the validity of this test. Just leave the room. And keep all doors and windows tightly shut. Thank you!

a. I like a very DARK bedroom for sleeping. b. I don't like dust in my bedroom. The bedroom windows are now completely sealed, which helps much with the reduction of dust infiltrating inside. c. You are correct about walking outdoors. Fortunately, I do have very nice areas to walk, with few cars, no roosters, and only friendly dogs. c2. But, I am lazy by nature. Overcoming inertia to return to daily walking is not so easy, or not until the time that one returns to the daily habit of walking. c3. Once out and about, of course, then the positive vibes of the flora and fauna immediately reinforces one. c4. The main problem, though, is that I live inside a very nice compound with birds, some mango trees, and plenty of myna birds. And, I find it difficult to leave this idyllic gilded cage.

It's just plain WRONG to hurt defenseless grad students.
