WEBVTT Kind: captions Language: en 00:00:00.170 --> 00:00:02.070 Air conditioners are pretty cool. 00:00:02.070 --> 00:00:03.020 *awkward pause* 00:00:03.020 --> 00:00:06.590 But there’s an increasingly popular variety of them that figuratively 00:00:06.590 --> 00:00:08.420 and literally sucks. 00:00:08.420 --> 00:00:09.420 That would be... 00:00:09.420 --> 00:00:11.080 these bundles of joy. 00:00:11.080 --> 00:00:15.760 Portable air conditioners seem to be taking the world by storm, or at least have taken 00:00:15.769 --> 00:00:18.940 the air conditioner isle of the hardware store by storm. 00:00:18.940 --> 00:00:20.260 But are they any good? 00:00:20.260 --> 00:00:24.400 Do these cold-making machines have what it takes to usurp the traditional window unit? 00:00:24.400 --> 00:00:25.380 No. 00:00:25.380 --> 00:00:28.400 Portable air conditioners are actually kinda… 00:00:28.400 --> 00:00:29.360 bad. 00:00:29.370 --> 00:00:30.980 Now it’s not like they don’t work! 00:00:30.980 --> 00:00:32.969 And some of them aren’t quite as bad as most. 00:00:32.969 --> 00:00:35.420 Plus, they can really come in handy. 00:00:35.420 --> 00:00:39.159 This one here is serving duty precisely because the window it’s venting through isn’t 00:00:39.159 --> 00:00:43.000 really suited to holding a window unit in place with any sense of confidence. 00:00:43.000 --> 00:00:44.980 And I know because I tried. 00:00:44.980 --> 00:00:47.719 Yes, this here is the symbol of my shame. 00:00:47.719 --> 00:00:50.410 The air conditioner that was never meant to be. 00:00:50.410 --> 00:00:54.320 But luckily for you I didn’t return it because it’s gonna be a great visual aid! 00:00:54.320 --> 00:00:58.280 Now, in this video I’m going to argue that if you need an air conditioner you should 00:00:58.280 --> 00:01:03.180 gravitate towards these simple window units and away from those trendy portable units 00:01:03.180 --> 00:01:04.710 *if you can*. 00:01:04.710 --> 00:01:08.320 And to find out why, we need to learn a little bit about air conditioning. 00:01:08.320 --> 00:01:12.900 Air conditioners are mechanical devices which collect and concentrate heat energy in order 00:01:12.900 --> 00:01:15.320 to move it from one place to another. 00:01:15.320 --> 00:01:19.610 The cold air they create is in fact ordinary air that’s had its heat energy sucked right 00:01:19.610 --> 00:01:20.740 out of it. 00:01:20.740 --> 00:01:23.280 And of course, we can’t just bottle that energy up 00:01:23.280 --> 00:01:25.920 (though that would be super cool if we could figure that out) 00:01:25.920 --> 00:01:30.280 so instead we move it somewhere else--usually to outside air. 00:01:30.280 --> 00:01:35.280 And inside every air conditioner you’ll find three essential parts that make that happen. 00:01:35.280 --> 00:01:40.500 This is the basis of nearly every air conditioning and refrigeration system in service today. 00:01:40.509 --> 00:01:44.659 The black cylinder contains a compressor which squeezes a gas called a refrigerant into a 00:01:44.659 --> 00:01:49.049 small space, decreasing its volume and increasing the pressure it’s under. 00:01:49.049 --> 00:01:52.789 The high pressure gas, which has now gotten quite hot thanks to the fact that it just 00:01:52.789 --> 00:01:58.509 got compressed, travels through these pipes into the second key component; the condenser. 00:01:58.509 --> 00:02:03.889 The condenser is a heat exchanger designed to cool that hot gas down as quickly as possible. 00:02:03.889 --> 00:02:08.610 The densely spaced fins increase its surface area to speed up the heat transfer, and a 00:02:08.610 --> 00:02:12.750 fan helps to speed it along even more by blowing air across the fins. 00:02:12.750 --> 00:02:17.470 Since the refrigerant is now pressurized, its boiling point has increased. 00:02:17.470 --> 00:02:21.180 And in fact, its boiling point has increased so much that once we get it down to something 00:02:21.180 --> 00:02:25.340 like 130 or 150 degrees, it will condense into a liquid. 00:02:25.340 --> 00:02:30.330 So, as the hot gas winds its way through all these pipes and its heat energy gets transferred 00:02:30.330 --> 00:02:36.240 to the air, it slowly turns into a liquid, releasing a ton of heat energy as it does so. 00:02:36.240 --> 00:02:37.960 Now here’s where the magic happens. 00:02:37.970 --> 00:02:42.540 That liquid is being held back by a metering device such as a thermal expansion valve, 00:02:42.540 --> 00:02:46.610 to keep the pressure high in the condenser and limit the amount of liquid refrigerant 00:02:46.610 --> 00:02:48.480 that can pass through. 00:02:48.480 --> 00:02:52.800 This basic air conditioner uses a capillary tube, a long copper tube with a very small 00:02:52.800 --> 00:02:57.220 internal diameter, to restrict the refrigerant and thus limit its flow. 00:02:57.220 --> 00:03:01.920 But once it makes it through to the other side, it finds itself in a second heat exchanger, 00:03:01.920 --> 00:03:03.560 called the evaporator. 00:03:03.560 --> 00:03:07.709 This one is functionally identical to the condenser, except the pressure inside here 00:03:07.709 --> 00:03:13.610 is much, much lower thanks to the suction created by the intake side of the compressor. 00:03:13.610 --> 00:03:18.549 Once inside here, the refrigerant can relax, and its boiling point suddenly shoots way 00:03:18.549 --> 00:03:22.200 way down, like into the well-below-zero territory. 00:03:22.200 --> 00:03:27.900 And that means it’s gonna spontaneously boil --or evaporate-- because, well, it’s 00:03:27.900 --> 00:03:30.129 too hot for it to remain a liquid. 00:03:30.129 --> 00:03:34.390 But to change phases back into a gas, it needs to get energy from somewhere. 00:03:34.390 --> 00:03:38.969 And luckily, the fins of the evaporator help it absorb the energy in the room, and the 00:03:38.969 --> 00:03:41.519 effect is that the room gets colder. 00:03:41.519 --> 00:03:46.469 In effect the heat energy inside the room is being used to warm up the refrigerant as 00:03:46.469 --> 00:03:47.989 it evaporates. 00:03:47.989 --> 00:03:52.780 Thinking about this can be kinda weird because we like to think of the evaporator as getting cold, 00:03:52.780 --> 00:03:56.319 which it is, but it’s getting cold because it’s pulling heat energy out of 00:03:56.320 --> 00:03:59.300 the air and into the refrigerant inside of it. 00:03:59.300 --> 00:04:04.180 Coldness is really just less concentrated heat energy, and since heat likes to go towards 00:04:04.180 --> 00:04:09.760 cold places to spread out, it naturally finds its way (with the help of a fan). 00:04:09.760 --> 00:04:14.420 After the refrigerant has absorbed as much energy as it can, it reenters the compressor 00:04:14.430 --> 00:04:17.330 where the cycle starts all over again. 00:04:17.330 --> 00:04:21.330 Once it’s under high pressure, it will be able to condense into a liquid again, releasing 00:04:21.330 --> 00:04:25.120 the energy it just absorbed to the outside air through the condenser. 00:04:25.120 --> 00:04:28.660 Now, I don’t want to get too far into the physics of how this works, nor talk about 00:04:28.660 --> 00:04:32.970 what makes refrigerants special and why they have been and continue to be a notoriously 00:04:32.970 --> 00:04:37.590 tricky set of chemicals to manage, so all I really need you to know for this video is 00:04:37.590 --> 00:04:41.280 there’s a compressor, a hot side, and a cold side. 00:04:41.280 --> 00:04:46.660 If we’re cooling a room, we want the hot side outside and the cold side inside. 00:04:46.660 --> 00:04:51.320 Then we can move the heat energy from inside the room to the outside air, cooling the room. 00:04:51.320 --> 00:04:56.160 So, let’s take a look at where these components are when the window unit is in operation. 00:04:56.160 --> 00:05:01.180 When resting in a window, the bulk of the machine is actually outside of the space it’s cooling. 00:05:01.180 --> 00:05:06.120 The compressor and condenser are both outside, and thanks to the generous amount of styrofoam 00:05:06.120 --> 00:05:09.210 insulation, we get a pretty good thermal barrier. 00:05:09.210 --> 00:05:14.240 When cooling, none of the actual air in the room is moved outside--only the refrigerant, 00:05:14.240 --> 00:05:17.710 and thus the heat energy it’s absorbed, makes it out. 00:05:17.710 --> 00:05:19.690 This maximises efficiency. 00:05:19.690 --> 00:05:24.260 If you have a central air conditioning system, you probably have what’s called a split system. 00:05:24.260 --> 00:05:28.550 Here, the compressor and condenser (along with a cooling fan) are contained in a single 00:05:28.550 --> 00:05:33.710 unit which sits outside, and copper refrigerant lines are run into the building to a separate 00:05:33.710 --> 00:05:38.040 evaporator located in an air handler or incorporated in a furnace. 00:05:38.040 --> 00:05:38.620 See? 00:05:38.620 --> 00:05:43.350 It’s a split system, as the evaporator and condenser are split apart. 00:05:43.350 --> 00:05:48.040 These systems are highly efficient, with the entire hot side located outside and away from 00:05:48.040 --> 00:05:52.550 the living space, and only a tiny hole is required in the home’s thermal barrier to 00:05:52.550 --> 00:05:54.540 move the refrigerant in and out. 00:05:54.540 --> 00:05:57.400 Alright, and now let’s take a look at a portable air conditioner. 00:05:57.400 --> 00:06:01.320 You may notice that the entire machine is inside. 00:06:01.320 --> 00:06:06.980 That means not only is the cold side inside, the hot side is inside, too. 00:06:06.980 --> 00:06:07.980 Well. 00:06:07.980 --> 00:06:08.980 That’s not great. 00:06:08.980 --> 00:06:12.920 We want the energy being absorbed by the evaporator and released into the condenser to make its 00:06:12.920 --> 00:06:14.400 way outside somehow. 00:06:14.400 --> 00:06:17.180 So, what to portable air conditioners do? 00:06:17.180 --> 00:06:22.270 They suck in indoor air through these vents, blow it across the condenser to cool it off, 00:06:22.270 --> 00:06:24.850 and then push it outside through that hose. 00:06:24.850 --> 00:06:26.750 That last sentence is very important. 00:06:26.750 --> 00:06:28.520 They pull in air through these vents, 00:06:28.520 --> 00:06:31.080 air that they just cooled, mind you, 00:06:31.080 --> 00:06:32.860 and blow it outside. 00:06:33.420 --> 00:06:35.900 That sounds pretty friggin stupid, just on its face. 00:06:35.910 --> 00:06:37.550 Now, it’s not like it doesn’t work. 00:06:37.550 --> 00:06:40.870 If these didn’t work they wouldn’t be nearly as popular as they are. 00:06:40.870 --> 00:06:41.680 Also! 00:06:41.680 --> 00:06:45.920 Two-hose portable air conditioners, which suck in *outside* air to cool the condenser 00:06:45.920 --> 00:06:50.830 and then blow it back out in two separate hoses, are available, but they are an increasingly 00:06:50.830 --> 00:06:54.640 rare part of the portable air conditioner universe and the vast majority on sale are 00:06:54.640 --> 00:06:56.990 single-hose units just like this one. 00:06:56.990 --> 00:07:01.210 So, if this machine relies on drawing air in through these vent slots to cool the condenser, 00:07:01.210 --> 00:07:06.880 and then has to barf the now hot air outside, that means not only is it sacrificing some 00:07:06.880 --> 00:07:11.580 of the cool air it just generated, it’s also creating a low pressure environment in 00:07:11.580 --> 00:07:13.610 whatever space it’s in. 00:07:13.610 --> 00:07:16.860 Now the air pressure outside room is greater than the inside. 00:07:16.860 --> 00:07:20.870 And that means that outside air is going to make its way in through the walls to replenish 00:07:20.870 --> 00:07:22.650 the air that just left. 00:07:22.650 --> 00:07:26.360 You can’t just expel air from a room without it getting replaced somehow 00:07:26.360 --> 00:07:30.030 (otherwise you’re in a vacuum chamber and I advise you leave as soon as possible). 00:07:30.030 --> 00:07:34.400 And what replaces it is ultimately the hot outside air that you’re fighting against. 00:07:34.400 --> 00:07:35.340 Genius! 00:07:35.340 --> 00:07:37.640 And thus we’re at the core of this issue. 00:07:37.640 --> 00:07:41.920 Single-hose portable air conditioners will always be significantly less efficient than 00:07:41.930 --> 00:07:45.770 a window unit because they’re not just pulling the heat energy out of your room. 00:07:45.770 --> 00:07:48.620 They’re also pulling the air out, too. 00:07:48.620 --> 00:07:52.670 In fact, if you go to a hardware store and take a look at a fresh assortment of portable units, 00:07:52.670 --> 00:07:56.470 you’ll often find that they have two cooling capacities listed these days. 00:07:56.470 --> 00:07:57.470 Why? 00:07:57.470 --> 00:08:02.610 Well, because newer testing methods are accounting for the losses brought about by this hose, 00:08:02.610 --> 00:08:07.370 so while the unit may technically be able to move 8,000 BTUs per hour, thanks to the 00:08:07.370 --> 00:08:12.200 warm air it’s drawing back in (as well as its own cold air it’s blowing back out) 00:08:12.200 --> 00:08:16.050 it’s effectively only moving 6,000 BTUs per hour. 00:08:16.050 --> 00:08:19.040 So, basically it’s 25% less efficient. 00:08:19.040 --> 00:08:21.200 But it’s actually much worse than that! 00:08:21.200 --> 00:08:25.790 This little 5,000 BTU window unit consumes 455 watts. 00:08:25.790 --> 00:08:31.440 If we take a look at this 5,500 BTU portable unit from LG, you’ll see that it uses over 00:08:31.440 --> 00:08:32.440 a kilowatt! 00:08:32.440 --> 00:08:37.459 That’s more than double the input power required to generate only 10% more cooling. 00:08:37.459 --> 00:08:43.120 A window unit that consumes that much power can produce roughly double the cooling capacity. 00:08:43.120 --> 00:08:44.270 So yeah. 00:08:44.270 --> 00:08:45.270 Eek. 00:08:45.270 --> 00:08:49.750 Now I’m not here to say that these are terrible devices and you’re a fool if you own one. 00:08:49.750 --> 00:08:53.689 ‘Cause I’d be calling myself a fool twice if that were the case. 00:08:53.689 --> 00:08:57.839 But I will say that in general, these should be your last resort. 00:08:57.839 --> 00:09:01.610 If you have the option to use a traditional window unit, take it. 00:09:01.610 --> 00:09:05.730 It’s much more energy efficient and it will cost less to run. 00:09:05.730 --> 00:09:07.259 And yeah, I get it. 00:09:07.259 --> 00:09:08.259 They’re ugly. 00:09:08.259 --> 00:09:09.259 They block your view from the window. 00:09:09.259 --> 00:09:12.180 They’re not exactly attractive from the outside either. 00:09:12.180 --> 00:09:15.319 But it’s not just energy efficiency that they’re better at. 00:09:15.319 --> 00:09:17.019 Air conditioners are noisy. 00:09:17.019 --> 00:09:21.240 They’re noisy because they’re mechanical devices, with a buzzy compressor and two droning 00:09:21.240 --> 00:09:23.300 fans moving air around. 00:09:23.300 --> 00:09:28.230 With a traditional window unit, the compressor and one of the two fans are outside. 00:09:28.230 --> 00:09:31.940 Thanks to that thermal insulation, you get a lot of sound insulation, too. 00:09:31.940 --> 00:09:36.040 You’ll certainly notice a difference when the compressor is on versus when it’s not, 00:09:36.040 --> 00:09:37.780 but it’s often pretty subtle. 00:09:37.780 --> 00:09:42.200 Especially because, as is the case for many windows units, the same motor drives the indoor 00:09:42.200 --> 00:09:47.760 blower fan and the condenser fan, so the only part that cycles on and off is the compressor. 00:09:48.080 --> 00:09:50.420 [sound of fan running] 00:09:50.720 --> 00:09:56.320 [sound level increases slightly as compressor kicks in] 00:09:57.320 --> 00:09:59.540 And of course, split systems are even quieter 00:09:59.540 --> 00:10:02.740 because the loud parts are nowhere near the living space. 00:10:03.320 --> 00:10:07.720 [compressor and fan switch on] 00:10:09.560 --> 00:10:11.220 Compare that to this thing. 00:10:11.230 --> 00:10:15.339 Not only is the compressor now inside the room you’re trying to work or sleep in, 00:10:15.339 --> 00:10:17.300 but so is the condenser fan. 00:10:17.300 --> 00:10:21.560 The result is that it’s not that noisy when it’s only running the circulator fan. 00:10:21.560 --> 00:10:26.320 But when its thermostat calls for cooling, it gets way, way louder! 00:10:26.320 --> 00:10:31.240 Suddenly, the compressor kicks in (which again, is inside the room) and a second fan turns 00:10:31.240 --> 00:10:33.540 on to expel the heat from the condenser. 00:10:33.540 --> 00:10:38.050 It’s a good thing the condenser fan shuts off when it’s not actively cooling, as otherwise 00:10:38.050 --> 00:10:40.660 it would suck even more air out the room. 00:10:40.660 --> 00:10:44.319 But it means there’s a stark difference in noise levels between not cooling. 00:10:44.320 --> 00:10:47.460 [a moderately quiet fan noise] 00:10:48.000 --> 00:10:49.120 And cooling. 00:10:50.300 --> 00:10:53.940 [compressor kicks in, and a second, much louder fan spins up at the same time] 00:10:54.200 --> 00:10:56.080 [it's really quite dreadful] 00:10:56.920 --> 00:11:00.800 And if you’re trying to sleep in the same room as one of these, you’ll have to put 00:11:00.800 --> 00:11:05.980 up with it going from pretty quiet to loud as hell and back over and over again. 00:11:05.980 --> 00:11:10.720 This is a cheap in-house brand unit from that place where you save big money so I wasn’t 00:11:10.720 --> 00:11:15.499 expecting it to be whisper quiet, but I’ve also got a more proper unit from LG that, 00:11:15.499 --> 00:11:19.310 while a little more elegant in the way it handles the transition from cooling to not 00:11:19.310 --> 00:11:24.160 cooling and vice versa, is still much much louder when it’s cooling. 00:11:24.480 --> 00:11:25.980 [fan noise] 00:11:26.720 --> 00:11:28.620 [a second fan spins up] 00:11:29.400 --> 00:11:32.280 [compressor kicks in] 00:11:34.880 --> 00:11:36.440 I’m a pretty heavy sleeper, and even for 00:11:36.449 --> 00:11:40.459 me it can be a challenge to ignore the thing and fall asleep. 00:11:40.459 --> 00:11:44.040 And another thing to consider is that while window units steal a bigger chunk of your 00:11:44.040 --> 00:11:46.300 windows, they don’t steal your floor space. 00:11:46.300 --> 00:11:50.980 Portable units aren’t small and they can’t sit flush against the wall thanks to the hose, 00:11:50.990 --> 00:11:54.550 so be prepared to re-arrange a little furniture. 00:11:54.550 --> 00:11:55.690 And by the way. 00:11:55.690 --> 00:11:56.690 That hose? 00:11:56.690 --> 00:11:57.690 It gets hot! 00:11:57.690 --> 00:12:01.649 That heat energy it just concentrated isn’t gonna go away without a fight, and since this 00:12:01.649 --> 00:12:05.879 hose isn’t insulated at all, some if it is coming right back into the room. 00:12:05.880 --> 00:12:07.100 Fantastic. 00:12:07.100 --> 00:12:07.900 But, I’ll admit. 00:12:07.900 --> 00:12:09.820 Portable A/C units are handy. 00:12:09.820 --> 00:12:11.200 Really handy. 00:12:11.209 --> 00:12:14.080 They don’t need proper installation like a window unit does 00:12:14.080 --> 00:12:16.110 (which is quite a pain, I might add). 00:12:16.110 --> 00:12:20.420 They can easily be moved from room to room thanks to the wheels they’re on 00:12:20.420 --> 00:12:22.440 (that’s why the call them portable). 00:12:22.440 --> 00:12:26.879 And they fit window types that might otherwise be unable to accommodate an air conditioner, 00:12:26.879 --> 00:12:29.500 such as vertical windows or even patio doors. 00:12:29.500 --> 00:12:32.700 You could even run them through a small dedicated vent, if you choose. 00:12:33.140 --> 00:12:38.700 But sadly, their single-hose design makes them, honestly, a terrible device when it 00:12:38.709 --> 00:12:40.149 comes to efficiency. 00:12:40.149 --> 00:12:43.439 I’d like to see more double-hose units available for sale. 00:12:43.439 --> 00:12:48.440 They’re still gonna have the noise and floorspace disadvantages, but they at least regain much 00:12:48.440 --> 00:12:50.260 of their efficiency back. 00:12:50.260 --> 00:12:55.460 Last year I tried a portable mini-split system, with a separate outdoor compressor and condenser 00:12:55.470 --> 00:12:59.939 unit, and an indoor evaporator unit connected via a flexible refrigerant hose. 00:12:59.940 --> 00:13:04.900 Sadly, my unit had a refrigerant leak and stopped working after a few weeks. 00:13:04.900 --> 00:13:09.920 It looks like that’s a common problem, but let me tell you it was blissful while it worked. 00:13:09.920 --> 00:13:12.250 Quiet, efficient, and effective. 00:13:12.250 --> 00:13:16.879 I’d like to see this product get more development, but I also understand that it’s got way 00:13:16.879 --> 00:13:19.370 more limitations than even a window unit. 00:13:19.370 --> 00:13:24.149 Unless you want to get creative with some sort of exterior wall bracketing, this is 00:13:24.149 --> 00:13:28.340 limited to a ground-floor room or a room with a balcony or something similar. 00:13:28.340 --> 00:13:28.840 But anyway. 00:13:28.840 --> 00:13:32.600 If we’re gonna keep using these things, can we please get more dual-hose units? 00:13:32.600 --> 00:13:37.430 I get that they’re less flexible, particularly with vertical or narrow windows, and so are 00:13:37.430 --> 00:13:42.689 probably less desirable, but hopefully with more people aware of the energy losses caused 00:13:42.689 --> 00:13:47.270 by continuously pushing the air out of your home, we’ll see increased demand. 00:13:47.270 --> 00:13:52.869 Still, if you’re looking for an air conditioner in a situation where a window unit could work--you’re 00:13:52.869 --> 00:13:55.579 seriously better off going with the window unit. 00:13:55.579 --> 00:14:00.740 Contrary to what you might think, portable units are certainly not an upgrade. 00:14:00.740 --> 00:14:01.740 Other than their portableness. 00:14:01.740 --> 00:14:03.640 That’s, that’s pretty cool. 00:14:04.200 --> 00:14:08.200 Thanks for watching, and I hope you found this video to be as cool as a correctly charged 00:14:08.200 --> 00:14:09.740 air conditioning system. 00:14:10.460 --> 00:14:14.700 I do want to explore air conditioning a little more because I find it fascinating. 00:14:14.709 --> 00:14:18.990 The way that we exploit the physical properties of certain gasses to make heat energy move 00:14:18.990 --> 00:14:22.260 where we want it to go is kinda mind-blowing. 00:14:22.260 --> 00:14:26.019 Oh, and by the way, not all refrigerants are crazy complex chemicals. 00:14:26.019 --> 00:14:30.180 Some small refrigerators and air conditioners are starting to be charged with propane. 00:14:30.180 --> 00:14:34.670 Propane, also known as R290, is becoming an increasingly common refrigerant thanks to 00:14:34.670 --> 00:14:38.060 its abundance and relative environmental harmlessness. 00:14:38.060 --> 00:14:42.410 Unfortunately it’s also flammable which makes servicing these a little tricky, and 00:14:42.410 --> 00:14:46.410 makes it unsuitable for larger units which need a lot of refrigerant. 00:14:46.410 --> 00:14:49.709 But especially for small, cheap units like these things that are likely to simply be 00:14:49.709 --> 00:14:53.300 disposed of when they die rather than actually serviced, 00:14:53.300 --> 00:14:55.360 it’s a great opportunity to use it. 00:14:55.360 --> 00:14:59.840 This machine, though, while it is charged with a flammable refrigerant, uses difluoromethane, 00:14:59.840 --> 00:15:01.040 or R32. 00:15:01.040 --> 00:15:04.810 Of course, thanks to everyone who supports the channel on Patreon, with a special thanks 00:15:04.810 --> 00:15:07.509 to the fine folks you see

--> 00:15:41.680 ...the cold air they create is in fact ordinary air, eh. 00:15:41.680 --> 00:15:43.680 Eugh, eugh blaugh ugh. 00:15:44.300 --> 00:15:46.980 I’m--this tone is all wrong. 00:15:47.940 --> 00:15:48.900 OK… 00:15:53.200 --> 00:15:56.280 maybe move at like a pace that makes sense. 00:15:56.280 --> 00:15:57.380 Yeah, that’s written wrong. 00:15:58.040 --> 00:15:59.440 Well, that’s fine. 00:15:59.960 --> 00:16:02.200 And now I will record that line as written! 00:16:02.660 --> 00:16:06.400 Or at least have taken the hardware isle of the air condition… the hardware! 00:16:07.300 --> 00:16:08.840 Arghh… nope. 00:16:08.840 --> 00:16:10.300 Air conditioners are nois… 00:16:10.360 --> 00:16:12.520 I should move this again. 00:16:12.520 --> 00:16:16.360 Coldness is really just less concentrated heat energy, and sint he… 00:16:18.100 --> 00:16:19.000 Augh! 00:16:19.000 --> 00:16:19.500 Sint. 00:16:19.500 --> 00:16:20.000 Since heat! 00:16:20.000 --> 00:16:20.500 SINCE heat! 00:16:20.500 --> 00:16:21.180 It’s a wo...the Since! 00:16:21.440 --> 00:16:21.940 Since is the word. 00:16:22.120 --> 00:16:22.740 Since.
