00:01:320Michele De Carli: Good, good stuff.
00:04:90Michele De Carli: So, we were here, okay, so,
00:13:980Michele De Carli: So, we were talking about today, about the,
00:23:490Michele De Carli: thermal output of a radiant system, okay? So,
00:30:800Michele De Carli: As we have seen, okay, the first step is to check the comfort and maximum or minimum temperatures, okay, according to comfort and other factors. And then, once you know that the system is able to provide the wanted
00:48:550Michele De Carli: Power, then you're going to decide the system.
00:54:450Michele De Carli: So, the… which are the main parameters which affect the, the, the thermal output of a radiant floor, okay?
01:07:200Michele De Carli: So here you see the, the parameters, okay? The parameters are these ones. There is the pipe spacing, which is, of course, important, okay?
01:20:270Michele De Carli: The thickness of the screen, which means… which is the thickness of the concrete where the pipes are embedded.
01:31:410Michele De Carli: The conductivity of the layer above the pipe, okay, so we'll see that.
01:40:260Michele De Carli: The floor covering resistance, okay, so which is actually, the ratio between lambda and the thickness of the material that… sorry, yes, vice versa.
02:02:520Michele De Carli: S divided by lambda, okay? So the thickness of the covering layer, which could be 1 centimeter, and in case of ties, it's contributing to 1, for instance, okay?
02:15:350Michele De Carli: or whatever you have. The external diameter of the pipe, okay.
02:21:410Michele De Carli: And, the thermal conductivity of the pipe, the
02:30:180Michele De Carli: factor evaluating the contact between the pipes and the, the, the screen? Okay.
02:38:760Michele De Carli: And,
02:41:340Michele De Carli: Okay, in case of the Type B, which is the one which have… these are for the type B, okay. In this case, type B is the one where you have the omega metal sheet, okay, with the pipe.
02:58:930Michele De Carli: Okay? So, in principle, okay, the heat transfer coefficient is a function of the temperature difference between the floor in the space and the air, but let's say that it can be considered, okay.
03:17:450Michele De Carli: almost, constant, okay? So we can, as a first, attempt or assumption, we can, consider that the
03:30:370Michele De Carli: surface per coefficient of the floor, okay, is not dependent on the temperature of the floor, okay? So, this is something that we can do, and actually.
03:40:790Michele De Carli: is saying what we had seen last night. So, at the end, okay, we have the thermal output of the radiant floor.
03:51:400Michele De Carli: These, this,
03:53:960Michele De Carli: coefficient, which is B, which is given for the different types of system, okay? We will see the types so-called A and C, okay?
04:06:430Michele De Carli: And, as I told you, okay, the interpolation function, which is the product of different parameters, AI to the MIS function, okay, and then the, temperature
04:21:880Michele De Carli: Difference between the average temperature of the water
04:25:270Michele De Carli: Okay, and the room temperature. Okay, so, let's say that this is… this is,
04:33:960Michele De Carli: the… the K… KH, okay?
04:42:390Michele De Carli: All right? So, at the end, what we have is the overall heat flux in terms of watts per square meter, okay?
04:55:160Michele De Carli: Okay, so the RL power given by the, by the, by the, by the radial system. Here you see, okay, the parameters.
05:06:350Michele De Carli: SU is the thickness of the layer above the pipe.
05:11:140Michele De Carli: the diameter of the pipe is, of course, important, and the spacing between the pipes, okay? These are the most effective parameters, as well as, okay, how then… so this is the screen, this is the concrete layer, the gray one, and the brown
05:27:590Michele De Carli: Layer is the, let's say, is the
05:34:930Michele De Carli: finishing material, okay? The, the, the surface material.
05:38:830Michele De Carli: Okay, so let's have a look, as I told you, all these parameters A, B, A, T,
05:46:740Michele De Carli: AB, okay, which is exponential 1. A, T, and MT. AU, MU, AD and MD, okay?
05:57:480Michele De Carli: These are the parameters, okay, which are listed in tables as a function of the other parameters, the geometrical parameters, pipe spacing, diameter.
06:09:620Michele De Carli: as well as the thermal properties of the materials, like the thermal conductivity, and so on, okay?
06:21:920Michele De Carli: Okay, so, we won't look that much about these parameters. You can see that some parameters are calculated, some are listed in tables, okay? You can see AB is, for instance, calculated, okay. MT is calculated based on T, okay, and AT, for instance, is 11.
06:45:430Michele De Carli: Okay, so some of the parameters.
06:47:590Michele De Carli: are calculated by the equation, some other parameters are instead interpreted as a function of other parameters, like, for instance, AU, okay, which can be interpreted by… as a function of the
07:04:830Michele De Carli: surface resistance layer, okay, and the type spacing, okay? So, all these parameters are listed here, okay? So, what we are going to see is the type AC, which means that these type of systems, okay, so what we are going to do is to
07:24:780Michele De Carli: to say, Consider, to… to consider that in your house, you're… you are installing the…
07:32:490Michele De Carli: usual, traditional types of gradient systems, okay? Of course, there are other calculation methods, okay? There is also another calculation method for the waves, okay, which are present instead of the pipes, let's say, inside the
07:49:880Michele De Carli: the insulation level, okay, but this is, I mean, the principle is similar, but then the coefficient change. So now, what I would like to say, okay, is what I want to show you.
08:02:970Michele De Carli: is how to deal with the Excel tool. Okay, so the Excel tool is, here designed, okay, let me switch
08:10:600Michele De Carli: to the Excel sheet, okay? So, what you have to see, what you have… sorry, what you have to choose, you have to select are the,
08:22:920Michele De Carli: cells that are in… well, I don't know which is its color, it's in orange, okay, dark orange, or…
08:32:809Michele De Carli: light brown, okay, or dark, you can see light, okay? I don't care. Here, what you can see is that you have the… you have both Italian and English names, okay? So, index, that's it, okay?
08:48:860Michele De Carli: And here, you have to, you have to, let's say, assume some values, okay?
08:55:110Michele De Carli: What is important to understand is that the thickness of the layer above the pipes, okay, SU, okay, which is this one here, this parameter, okay.
09:10:240Michele De Carli: should be at least 1 centimeter, okay? This is the usual… this is for, let's say,
09:20:120Michele De Carli: load structure loads, okay? So it could be 1, 2, 3 centimeters, whatever you like. You are free to decide. You're also free to decide the pipe spacing and all the other stuff, also the diameter of the pipe, okay? So, of course.
09:39:610Michele De Carli: Based on this, you have the thermal output on the floor, okay? So, we will consider… you will consider to have radiant floor in the house, and then…
09:53:630Michele De Carli: you are dealing with the heavy on the floor, okay?
10:00:580Michele De Carli: Based on this, you are going to calculate the terminal output, okay, which is,
10:07:940Michele De Carli: Here, this is the, the heat flow that is going towards the upper space, okay? And, and of course, you have to fume this.
10:19:560Michele De Carli: value here according to the load that you have in your house. So you have to calculate the peak load in heating, you divide by the floor area, okay, and then you are going to
10:32:380Michele De Carli: play with the different geometrical factors, okay, and thermal properties factors, in order to have this value, which reaches, okay, your time around. Okay, so in that case, you know that if you… for instance, you have
10:49:670Michele De Carli: 74 watts per square meter, okay, as the thermal output, okay? Imagine that you have 10 square meters, and you have 70, 140 watts as peak load, okay, in the design heating condition.
11:05:70Michele De Carli: Then, 74 divided by 10, 740 was divided by 10 is 74, that's the truth. So for this room, that will be okay, okay?
11:16:390Michele De Carli: And you're going to work on it. Of course, remember that, I mean, you can do whatever you like. You can also work with different finishing materials, if you want to work with wood on the…
11:30:660Michele De Carli: Bedrooms, and, like, ties, and your kitchen, whatever you like, you like.
11:35:200Michele De Carli: good, you can work with good anywhere, okay? So you're free to decide whatever you like. But remember that the thickness of the overall structure should be the same, okay? So, if you're using
11:47:320Michele De Carli: So the… let's say that SU, and also the diameter of the pipe is the same everywhere. You will not buy two different pipes for different…
11:56:950Michele De Carli: Let's say, rules, okay?
12:01:840Michele De Carli: So, the geometric agaristic of the pile and the screen will be more or less the same. Of course, if you want to put 2cm of wood in the bedroom, and you want to use 1 centimeter of time in the kitchen, okay, of course, there will be a difference in the screed, okay, thickness.
12:20:320Michele De Carli: But you're not… I mean, you can do it in an easy way, okay? So…
12:28:890Michele De Carli: What you can blame on is they.
12:32:600Michele De Carli: pipe spacing, and of course, the temperature of the water in the pipes, okay? We come to this point later. Once you have estimated the overall, the heat flux, okay, room by room, okay, this is the output of the
12:52:240Michele De Carli: Of the radiant floor, okay, but… Okay.
12:58:130Michele De Carli: It's just a part of the… it's just a part of the lead flow, okay? So,
13:07:710Michele De Carli: Okay? So, it's just part of the flow, because
13:14:60Michele De Carli: depending on what you have, install 3 centimeters of insulation, okay, I told you, we will consider that below your house, it will be… it needs space, okay, so…
13:27:120Michele De Carli: We don't care about any other boundary conditions, okay?
13:32:150Michele De Carli: They… Indeed.
13:38:930Michele De Carli: Okay, this is… this is the… Mmm, so… This is the… the,
13:47:950Michele De Carli: upward, okay, this is the KH times delta theta H, is the, okay.
13:56:910Michele De Carli: Up the upper stream, let's say, okay, the heat that is going on the upper room, the downward stream is related to the resistance that you have
14:10:570Michele De Carli: Here under. And the overall resistance, and the, in the resistance, 25.
14:17:610Michele De Carli: Okay, so considering the two resistances that you had, okay, then you can calculate the Perlanosis.
14:28:840Michele De Carli: Below, okay, which are going on the bottom of
14:34:20Michele De Carli: On the, on the bottom level, okay? Of course!
14:44:770Michele De Carli: Power which has to be delivered by the water.
14:48:520Michele De Carli: should face both.
14:52:510Michele De Carli: Lefts?
14:56:90Michele De Carli: Not only the upper floor, but also below 60km below, okay?
15:01:690Michele De Carli: So, then… they… Plurate that you… you will assume a certain quantity, Underwaters, of course.
15:13:70Michele De Carli: And then… and then the machinery will consider
15:17:550Michele De Carli: Not only the the malar output, but also the losses that you have, that you have. Okay?
15:24:570Michele De Carli: And this is already included in the calculation, okay?
15:29:400Michele De Carli: So, now we have a look at the Excel sheet.
15:35:840Michele De Carli: Okay to switch.
15:53:900Michele De Carli: Okay?
15:57:110Michele De Carli: No!
16:01:730Michele De Carli: Okay.
16:04:40Michele De Carli: And I have to…
16:17:290Michele De Carli: All right, so this is, okay, this is the fraction that you have to deal with, okay?
16:24:720Michele De Carli: So, as I told you, as I told you, as I told you, okay, here you have the Italian and the
16:31:500Michele De Carli: Ended the, and the… English.
16:40:940Michele De Carli: Okay, so I can reduce it a little bit.
16:48:80Michele De Carli: So, this is the pipe spacing, okay, 10 centimeters, you can…
16:53:170Michele De Carli: You can play with it, okay? This is the external dimension of the pipes, okay? You can have… I told you, okay, usually
17:04:990Michele De Carli: For radium floors, you use between, let's say, 15 to 18, 20, okay, millimeters outer diameter. You can also have a look at the different pipes that you have. Remember that for the pipes, for the radial system, the plastic pipes, okay, usually used.
17:22:339Michele De Carli: You heard that, then, you can say…
17:26:710Michele De Carli: 16 times 2. Okay, what does it mean? That the first
17:31:180Michele De Carli: figure is the outer diameter, and this is the thickness of the… of the… of the pipe, okay? 16 by 2 is 16 extended diameter.
17:42:860Michele De Carli: And this is the thickness, which means… Love.
17:49:150Michele De Carli: millimeters, okay, as in another, okay?
17:54:30Michele De Carli: Okay, so then, you have the thickness above the pipes, the thermal conductivity of the screen, okay.
18:05:600Michele De Carli: So, of the concrete layer, this is the resistance of the floor covering. You can see this is calculated, okay, so you can go, and you can… there are also where you have the… I told you the…
18:21:670Michele De Carli: whatever color you like to say, okay, this is, dark pink, okay. You can see this is the thickness and the material, so this is…
18:31:800Michele De Carli: For instance, the, tile, okay, 1cm on one, and this is the glue, okay, that is usually used, okay, for…
18:43:770Michele De Carli: Okay, for… We're not touching the, the, the, the…
18:47:820Michele De Carli: Then, the ballast for the game.
18:50:900Michele De Carli: Here you have the questions, just in case, okay, so you can have all the reference here. And, SL is the, what, the thickness,
19:06:810Michele De Carli: below the pipes, okay? So in this case, you consider that the pipes are, let's say, in the center of the concrete.
19:14:130Michele De Carli: Insulation layer, thickness.
19:18:600Michele De Carli: thermal conductivity on the insulation layer, okay, the thickness of the slab, the resistance of the slab, thermal resistance of the slab, and then you have the plaster below the slab, okay? So the plaster.
19:34:450Michele De Carli: That you have on the ceiling, on the roof, on the, on the, on the ceiling.
19:38:890Michele De Carli: Of the attention room. This is the floor area, so here you have to put the floor area that you have in your room. Okay.
19:49:650Michele De Carli: And this is… and here is the need of the
19:54:450Michele De Carli: the peak load that you have calculated. So you have to do the calculation room, okay? So here you have to put the load, so the flow area, and the power that you have calculated based on your calculations, okay? So the resulting… the resulting is the
20:11:970Michele De Carli: the immediate, okay? This is the two need, which is the…
20:19:210Michele De Carli: is the ratio between that, okay? And now, here, okay, on the bottom part, you have the indoor temperature, you can put 20, okay? And this is the…
20:32:980Michele De Carli: They, the, the… You have to put the supply temperature, okay, and the,
20:44:760Michele De Carli: and the delta P that you have between supply and return, okay? So this is the supply, temperature, 33, and this is 2 degrees, okay? So you can put, for instance, 3 if you want here, okay? Or you can put 4, okay, and you have
21:00:170Michele De Carli: the resulting. So in this case, if you put 3, this is 66.4 is 5, okay, so it's okay.
21:08:900Michele De Carli: So, the first check is that this value, okay, should meet the value that you have on top, okay?
21:17:590Michele De Carli: Then, based on that, of course, you have assumed that you have 10 centimeters of spice facing between one pipe and another, okay? In the below, in the following rows, okay, you have
21:34:570Michele De Carli: the maximum temperature is straight line, okay? And here, you have the temperature that you have in the lower space, okay? So, in the attitude. Frank is okay, because we assume that you have heated space.
21:50:110Michele De Carli: And you can see that, the, the QG is the maximum.
21:56:40Michele De Carli: the one related to 29 degrees C, okay, so you can see it's…
22:00:620Michele De Carli: 89, not 90, but it's okay, okay, because you're considering the 2D, okay, better than we did. And you can see here, 82.3. This is the flow rate… sorry, it's the heat flow.
22:16:530Michele De Carli: So the sum of the 70…
22:19:480Michele De Carli: 6, okay, plus the losses that you have, that you have already, okay, that you are considering below the…
22:26:650Michele De Carli: the room, okay? So it's 76 plus 60, okay? So, plus 6. So 6 walls per square meter are the losses that you are… that are going in the additional space. If you have, for instance, for instance, here you can consider… if you consider an ammity space.
22:45:240Michele De Carli: So you can see that… So… My fellow shots of magazine.
22:56:300Michele De Carli: I see, sorry, sorry, no, this is… Okay.
23:01:10Michele De Carli: Okay, this is 10, sorry, I… Okay, in this case, you can see 88. So, usually, in order to reduce this loss, okay, you… you use a greater thickness of the insulation, okay? So, the…
23:18:410Michele De Carli: Thickness of the insulation is 0.06, for instance, okay?
23:23:230Michele De Carli: So, by increasing the thickness of insulation, you can add…
23:27:110Michele De Carli: you can reduce the downward close, okay? So, usually, it is recommended, it's also required by the standard, to increase the insulation
23:37:160Michele De Carli: If you are going to have small… lower and lower temperatures below the floor, which could be, for instance, against a space which is unheated, the ground, for instance, or
23:50:570Michele De Carli: R… Or, for instance, outdoor temperatures, because you could do that with this, okay?
23:58:170Michele De Carli: So, now…
24:00:920Michele De Carli: So usually, just to, you can use here 3 centimeters. Usually, you use 3 centimeters of insulation, okay? So you can see, with 3cm of insulation.
24:13:90Michele De Carli: Okay, 0035 is okay. You can have, you can see here, it's 83.5, okay, so it's a little bit more, but not that much as before.
24:23:570Michele De Carli: Now, what do you have on the lower part? Okay, so you have selected… so what you have to do is to, let's say, adjust the
24:35:320Michele De Carli: geometry, okay? So you want to work with different
24:39:180Michele De Carli: diameters of the pipes, the pipes will be the same in all the rooms, okay? You should not, or would not probably, okay, work also on the thickness of the concrete layer, okay, as well as the thickness of the
24:55:980Michele De Carli: of the insulation, okay? So you will assume to have the same surface, the same thickness everywhere. So what you will work on will be, basically, on one hand, the pipe spacing, because you can add different pipe spacing
25:12:100Michele De Carli: from room by room, and then supply temperature, okay? So, of course, the most critical room will be the one with the greatest
25:25:320Michele De Carli: Specific power, okay? So, in this room, you will probably will use smaller part distance and greater temperature, okay?
25:35:990Michele De Carli: And once you have reached the goal, once the… the outflow that you have, so this…
25:46:20Michele De Carli: power, the specific power that you have in the room, is met by the temperature of the water, okay? Then…
25:55:540Michele De Carli: this… this would be fine. Of course, you know, later on, you could have different pipe spacing, and as I told you last time, the area divided by the pipe spacing provides the
26:08:160Michele De Carli: length of the pipes, okay? So, this is the overall length of the pipe, and of course, now it's up to you if you want to use 1, 2, 3, 4, 5 circuits, as many circuits as you like. How should you consider the length of the circuits?
26:26:550Michele De Carli: We didn't do that, but can you imagine?
26:30:970Michele De Carli: In the… in the pipe, you will have what?
26:34:530Michele De Carli: distributed?
26:36:80Michele De Carli: losses, okay? You have distributed losses. The longer the type.
26:43:110Michele De Carli: the greater the overall loss, okay? So, you can see that here, the losses are usually okay.
26:51:980Michele De Carli: You can use whatever you like, but usually people, okay, engineers, they work with meter a water column, okay? As long as you stay in the earth, okay?
27:03:950Michele De Carli: Okay, we are also thinking about, okay, conditioning missions and so on, but let's say that, I mean, as far as you work on that, okay, you usually work with meter of column normal, okay?
27:18:710Michele De Carli: So here you see, with one circuit, you have 13 meters of water column, okay? With two circuits, you have two
27:28:660Michele De Carli: meters of water column with 3 circuits, you will have zero power supply.
27:34:560Michele De Carli: Which is the recommended value of, overall loss?
27:39:580Michele De Carli: Along across one circuit.
27:45:770Michele De Carli: What do you… I know you don't know that, but I mean… Mr. Clarin.
27:53:270Michele De Carli: Less than 5? Less than 5 for sure, yes. A little bit less than 5. How much?
27:57:770Michele De Carli: Good booking.
27:58:960Michele De Carli: 223. 2, 3. A little bit,
28:03:910Michele De Carli: One. One would be the perfect thing. Usually, you have… the best would be to have one liter column of water in the secret, and one liter column of water in the water.
28:15:830Michele De Carli: And this is the usual.
28:19:140Michele De Carli: rule of thumb, okay? So, it's up to you if you want to have less
28:24:810Michele De Carli: Pressure losses, 0.6, okay. 1.9…
28:29:770Michele De Carli: might be okay, okay, but it might be a little bit high. Remember, remember, remember, remember, remember, okay, what?
28:41:80Michele De Carli: As we're going to see.
28:44:100Michele De Carli: The greater… no, sorry, the… okay, the greater the insulation level of the building, the lower is the thermal need, the heat… the thermal need of the building.
28:56:530Michele De Carli: that… The smaller the need of the building, the greater the
29:02:260Michele De Carli: sharing of auxiliary systems, okay? So, when… since we are going to work with more and more
29:11:30Michele De Carli: efficient buildings, okay? If you want to make a building, an HVAC, even more efficient, you have to pay… you have to pay, really, lots of attention about the auxiliary, okay, energy. Obsidiary energy can be, in some buildings, as much as the energy need.
29:28:500Michele De Carli: Okay? If you think about electricity, okay.
29:32:30Michele De Carli: Like, did Vivian show you the… no, okay, in Amazon Buildings?
29:38:150Michele De Carli: Okay, so if you have a very well insulated building, okay. If you work with, two, with two water and…
29:48:400Michele De Carli: to meter, what I call it. It might be that the electricity spent for the
29:56:90Michele De Carli: auxiliates for the pump is the same as the electricity spent for the heat pump, okay? So.
30:04:330Michele De Carli: The lower, the better, okay?
30:07:340Michele De Carli: But, of course, you will have, as we see, some, anyway, needed losses, okay, so needed, pressure drops, okay, because you need also to balance the system. In any case, this is… so you are… you are free, but I would… I would, okay, preferably work with this
30:25:140Michele De Carli: 3Cs, then, instead of two.
30:27:810Michele De Carli: Okay? Yes, please.
30:29:380Michele De Carli: Okay.
30:30:780Michele De Carli: Okay. All right, so, should not exceed. Don't worry about the fact that this turbulent laminar
30:43:490Michele De Carli: Doesn't matter, okay? So it's better to have lower pressure losses and work in laminar condition than working in turbulent flow and the greater pressure loss, okay? Also because, as you can imagine, the greater resistance is outside the pipe.
30:59:620Michele De Carli: Okay, so this is the most relevant resistance, rather than in the inner resistances, okay?
31:06:860Michele De Carli: That's it.
31:09:870Michele De Carli: Finished?
31:11:620Michele De Carli: Not yet.
31:13:300Michele De Carli: Okay? I told you.
31:31:920Michele De Carli: What are these two cylinders?
31:37:00Michele De Carli: We have two cylinders.
31:39:410Michele De Carli: We have pipes flowing from once an email, Let me What happens in the manifold?
31:48:660Michele De Carli: Hosses, of course.
31:55:40Michele De Carli: category, not the spread templates, right? Yes. Okay.
32:00:240Michele De Carli: So… If you calculate the output by room, you will have different It's correct.
32:12:240Michele De Carli: Okay.
32:13:200Michele De Carli: But in principle, what should you do? You should work with a…
32:18:70Michele De Carli: the water, I told you, you can play with the type spacing for meeting the goal, you can work on the type spacing, and on the
32:27:370Michele De Carli: Temperature.
32:28:760Michele De Carli: Of the supply, okay?
32:31:190Michele De Carli: So, room per moon, you will have impact, supply time, just based on your calculations, but in reality, you will have
32:39:190Michele De Carli: Beautiful.
32:40:60Michele De Carli: only one supplied that protein. So what… which… Supply temperature will you choose?
32:48:370Michele De Carli: The highest one, okay? So, you have to make first a calculation.
32:54:740Michele De Carli: To check the temperatures, and to check the
32:58:280Michele De Carli: The, types spacing, and so on.
33:01:930Michele De Carli: And then, when you reach the room with the greatest temperature.
33:07:410Michele De Carli: Okay, then you have to go back to the other rules and calculate the
33:14:200Michele De Carli: you… we work on the macro rate, on the delta T, let's say, okay?
33:19:270Michele De Carli: Why are they having the same sugar?
33:22:70Michele De Carli: You can also do the same by fixing them.
33:25:390Michele De Carli: By checking, there's maximum.
33:27:430Michele De Carli: Again, specific power.
33:30:200Michele De Carli: you work with this, you calculate the temperature, okay, then this red temperature is the one that you're going to use. And then, based… and then once you install the system, you will play
33:42:860Michele De Carli: You will control the master rate in each circuit in order to have, okay, a balance, okay?
33:49:720Michele De Carli: It flowed in the country.
33:52:00Michele De Carli: Okay?
33:56:290Michele De Carli: That's it.
33:57:790Michele De Carli: Okay, so for the bathroom, you can do a simplified calculation, not considering the other stuff, okay? If you want, you can consider also an auxiliary system in the bathroom, because probably you will not reach the power, okay? You're not obliged to
34:14:949Michele De Carli: consider also Veravito, okay? But if you want, you can consider Beravito, okay? In this case.
34:21:389Michele De Carli: You should consider that the temperature of the water will be the same as CFV.
34:29:690Michele De Carli: You can… you can have also two different temperatures, okay? But, I mean, in the past, when you worked at the boiler, you had
34:39:600Michele De Carli: two different supply temperatures, one for the radiators and one for the radar system, but if you work with a heat pump, it will probably work with a radiator at lower temperature, so with the same temperature of the lower temperature, okay?
34:56:219Michele De Carli: I mean, you're not obliged, okay? If you want, if you want to look and play, you can do that, but you're not obliged, okay?
35:02:860Michele De Carli: Okay?
35:04:820Michele De Carli: Alright?
35:06:700Michele De Carli: Yes?
35:11:320Michele De Carli: will be the total minus the average loss of the student level.
35:25:660Michele De Carli: You consider this a screen.
35:28:370Michele De Carli: Okay.
35:30:390Michele De Carli: You should… room by room, you consider if you have one… one floor above the other, you don't consider the heat that you have.
35:40:480Michele De Carli: Okay?
35:43:50Michele De Carli: This will be a part of regulation of the control.
35:46:830Michele De Carli: But not for sizing.
35:50:910Michele De Carli: Okay?
35:54:330Michele De Carli: Okay, so you can see that the…
35:57:440Michele De Carli: the… the one who identified was Zakai Mi, okay? He's now a research professor in, UF, University of Venice, okay? So…
36:09:700Michele De Carli: Okay, good.
36:16:90Michele De Carli: Juliet is fine.
36:18:630Michele De Carli: Slide.
36:19:500Michele De Carli: I downloaded from Moodle, and yes, it's in Moodle, in the Radiant System section, okay? Yes.
36:27:690Michele De Carli: Okay. I also uploaded the table of contents on your personal report.
36:33:600Michele De Carli: Okay, if you want to look at, okay? I mean, we don't need points, okay? We need the…
36:39:400Michele De Carli: really simplified or schematic, okay, text, but clear enough, okay, just to know which is the age of your building, what did you use, you can… and I… you have to send us all the Excel sheets that you are.
36:55:150Michele De Carli: award, they won the Olympia, okay?
37:01:220Michele De Carli: What? In order different things.
37:08:270Michele De Carli: You can do it, but we do work on the Word… the Word document, okay?
37:14:540Michele De Carli: Latin is not used, is not used, okay? You, in real world, is not used, is shit, okay? So, I mean, for the next 5 years, I think, maybe more, okay, but for the next 5 years, I don't expect
37:31:610Michele De Carli: Engineering companies working with Latinx, okay?
37:35:670Michele De Carli: I mean, as far as, you will not be the older ones, okay, in the company, and then you could say, let's switch to Atlantic, okay? But that will happen in 20 years from now, so…
37:47:670Michele De Carli: But I would expect that in the next 15, 20 years, I don't expect that LaTeX will be the most used software in engineering.
38:01:210Michele De Carli: Meanwhile, you probably will LATIC, I don't mind, but I want to see one, okay?
38:06:150Michele De Carli: I wrote LATIC. I wrote Word even, because it's… every time, okay, you had to update, okay, so for me, it was much better the world that it was before, even though it was unstable, okay? So, you can do LATIC, yes, but I want also the word, okay?
38:25:690Michele De Carli: Okay.
38:31:630Michele De Carli: Any other questions?
38:33:890Michele De Carli: Okay.
38:35:340Michele De Carli: Alright, so…
38:40:40Michele De Carli: I think that's all. Okay, we could say more things about… but I think that for the radio systems part.
38:48:220Michele De Carli: we are done, as well as all for… also for, let's say, the emission systems in China. Okay, so we…
38:55:890Michele De Carli: Then, we are going to start with the new section, which is the hydronic system, okay? So the hydraulic systems, okay? So, I will…
39:10:770Michele De Carli: Stop the recording.
39:13:440Michele De Carli: Excuse me. Okay.
39:16:130Michele De Carli: True.
