00:03:20Michele De Carli: Okay, so…
00:10:580Michele De Carli: So, as first, we are going to… I would like to show you, okay, a typical, reference of this document in Windows. All right, so, this is, the…
00:24:360Michele De Carli: It's a factory of paper, UC radiators, and I mean,
00:30:750Michele De Carli: what I wanted just to show you, okay, was that, depending on the, on the type of radiator, okay, here you have some, some,
00:43:270Michele De Carli: Some, for reference leaders, it's great for the constant of the…
00:54:140Michele De Carli: Well, they draw some dogs in it.
00:58:740Michele De Carli: Oh, God.
01:01:960Michele De Carli: Right, for the concept, the characteristics of the radiator, and also…
01:10:240Michele De Carli: There is not the end, the silent.
01:12:890Michele De Carli: Okay? Okay, so, here you have for several types of, reinforce, okay, for different types of indicator, you have some reference figures that you can,
01:27:880Michele De Carli: in case views, okay? This is just to show you, okay, how the coefficient is
01:34:800Michele De Carli: is, can be used, okay? This is…
01:39:360Michele De Carli: And that's… and that's it, okay? For N, usually you have around about, okay, between 1, 2, 1.2 and 1.15 and 1.35. So you can use as, let's say, rough estimation, a coefficient of…
01:58:240Michele De Carli: 1. Okay, so, this is, okay, can be useful for you in future, in case you will need some tentative figures, and you don't know exactly the type of regulator. For instance, you are going in.
02:16:590Michele De Carli: In an existing building, and you would like to use that.
02:20:20Michele De Carli: All right, so, we, go on, we continue with the radiators, okay, so, and,
02:31:990Michele De Carli: rearrange the… Okay…
02:45:260Michele De Carli: Okay, beautiful.
02:52:420Michele De Carli: Alright, so,
03:00:350Michele De Carli: Sorry.
03:06:450Michele De Carli: Oh.
03:08:610Michele De Carli: Okay, so, what, what's next?
03:14:450Michele De Carli: So, we have seen how to size the regulators, okay? So, we have seen the best we can use.
03:20:590Michele De Carli: there is this equation that we can use, okay? And, I mean, this is the equation that the one factor can, or, uses, okay, for defining the power that can be
03:38:300Michele De Carli: can, can be given by a radiator, okay? So, it is basically the constant,
03:49:110Michele De Carli: the constant K, KNK, or… There is this, okay, S, just for your, let's say,
03:57:500Michele De Carli: Peter, here you have some examples, okay, or you can go in the other, in the other,
04:04:510Michele De Carli: in the other… you can have some exceptions that I have just shown you, okay? And you have the explanation, okay? Now, basically, the actual power of the radiator, okay.
04:20:760Michele De Carli: Since we can write.
04:23:650Michele De Carli: the nominal, for the nominal power of the radiator. Okay, so how in light equations.
04:29:740Michele De Carli: So we can say, like, the nominal power of the reactor East. K. N. Times.
04:38:600Michele De Carli: 50 bands, okay, and the extra power of the radiator.
04:45:240Michele De Carli: ECN.
04:52:150Michele De Carli: Right? If we divide one by the other, okay, so if we divide the actual, divide it by the… now we have to take the extra.
05:03:20Michele De Carli: Divided by the nominator power.
05:10:640Michele De Carli: He value my strength.
05:20:110Michele De Carli: You got extra minutes of time, okay?
05:23:50Michele De Carli: All right, so, what does it mean? What is poo nominal, and what is pooatin? So, konomous is, let's say, and let's imagine that you already established, okay, the amount of
05:37:690Michele De Carli: And let's setting up in a certain, room, okay?
05:42:320Michele De Carli: So, what is gonomina?
05:47:700Michele De Carli: Think about a loop, Okay? What is the culinary?
05:53:470Michele De Carli: The nominal power. What is the nominal power?
05:59:140Michele De Carli: We're late.
06:05:80Michele De Carli: Design.
06:06:130Michele De Carli: What means design?
06:08:850Michele De Carli: the powers around which radiators. No, let's… let's think about that you… I mean, you can merge the power of these radiators, okay? Imagine that you can consider a certain
06:21:290Michele De Carli: powerful. They're already to some spider, and…
06:27:520Michele De Carli: In which conditions? In which conditions? Design conditions. To worst case conditions. Worst case, what is this? Minus 5 degrees outside. Design temperature outside conditions, okay? Alright, so this is…
06:43:420Michele De Carli: Amen.
06:47:890Michele De Carli: the temperature, okay?
06:50:680Michele De Carli: This is the temperature.
06:52:610Michele De Carli: And this is, of course, here, The minimum is there.
06:58:760Michele De Carli: They got me.
07:00:840Michele De Carli: Okay, 0 degrees, minus 5, and minus 10, minus 15, minus 10, 20, okay, depending on the building, on the building,
07:11:570Michele De Carli: So… Depending on the outer design.
07:18:680Michele De Carli: Noth.
07:22:310Michele De Carli: Let's imagine that here we have… we are considering the power. So we want to, let's say, Try to…
07:30:680Michele De Carli: Define the power according to the outer temperature.
07:40:920Michele De Carli: So here, Will we laugh.
07:48:110Michele De Carli: Right?
07:49:990Michele De Carli: This is the power to design condition.
07:54:670Michele De Carli: Yes, moments? Yes? Okay.
07:59:810Michele De Carli: Which is the outer temperature, when we could assume that the power
08:05:410Michele De Carli: That we need in a billion is zero.
08:08:80Michele De Carli: When it is equal to the indoor temperature.
08:11:870Michele De Carli: If there is no… When it is assumed that you don't need heating.
08:19:00Michele De Carli: Not 3 electronics.
08:23:400Michele De Carli: Do you remember the… Degree day. Definition.
08:30:270Michele De Carli: When, there is a threshold template, yes. Mine is one, all of it.
08:41:900Michele De Carli: When is the outdoor temperature? When it is assumed that you don't need? Okay, it's 20 if you have no solar radiation, but if you have solar radiation internal gains, then you can assume to have a little bit more… sorry, lower temperature than traditional.
08:57:40Michele De Carli: Your dress! Looks.
09:03:250Michele De Carli: How do you do the calculations for the energy demand of the… of the B?
09:09:560Michele De Carli: Your calculation.
09:13:570Michele De Carli: Oh, let's touch here. Which are… how do you calculate the design for me?
09:19:870Michele De Carli: we set the design temperature inside, and we hypothetize, I don't know, minus 5 degrees outside. We have the metric design.
09:33:840Michele De Carli: We know this in the time swap.
09:37:420Michele De Carli: We know it.
09:43:970Michele De Carli: How do you calculate the composition of our walls? Yes, what is the, what is the factor of the division value?
09:52:00Michele De Carli: in revenue. It may be included in this… Refugee
09:56:500Michele De Carli: I always hold it. I'm saving it.
10:02:900Michele De Carli: Okay?
10:04:350Michele De Carli: And this is the… HD.
10:07:530Michele De Carli: HD?
10:09:880Michele De Carli: Transmission the transfer efficient.
10:12:80Michele De Carli: Thus, HB.
10:22:220Michele De Carli: Right?
10:23:500Michele De Carli: Okay? So the… we have the total over… the overall heat transfer equation based on, okay? And…
10:33:670Michele De Carli: What do we use for the
10:39:780Michele De Carli: Energy command of the demons.
10:43:250Michele De Carli: The username, H starvation.
10:46:470Michele De Carli: Thrives?
10:50:90Michele De Carli: Or the energy… Be greetings. Good greetings.
10:56:110Michele De Carli: There is no longer.
10:58:470Michele De Carli: What does it mean?
11:06:220Michele De Carli: means that the total losses I have through all year. Through all year, which means also in average conditions. Okay, so it is a linear.
11:15:880Michele De Carli: Official?
11:19:450Michele De Carli: Where you could replace
11:22:560Michele De Carli: The outer temperature, the inner temperature, 24 degrees C, the inner temperature, or the inner temperature minus outward temperature.
11:31:670Michele De Carli: Right?
11:33:110Michele De Carli: So there is… this is the linear correlation between the Temperature outside, And the power needed
11:45:170Michele De Carli: Average power in a certain movement, okay?
11:52:400Michele De Carli: So, is this… Be…
11:55:490Michele De Carli: hypotheses that we use for making the calculations with the overall transfer coefficient? Can we say that?
12:07:260Michele De Carli: Yes, sir.
12:09:140Michele De Carli: Yes?
12:10:180Michele De Carli: Okay, good. So this is, of course, an approximation, because we don't consider the antenna gauge, we don't consider the solar gauge, we don't consider the capacity of the walls, okay? But this is depending on relationship, okay? Actually, when we consider, of course, this is
12:27:200Michele De Carli: more accurate when we consider larger periods of times, okay, larger ranges of time, okay? So, if we consider, for instance.
12:35:750Michele De Carli: Daily values or monthly values, okay? This is, at the end, the so-called signature of our data, okay? We will do that in the… who is doing the energetic calls here?
12:49:200Michele De Carli: Okay, so you will see that, okay? Of course, the longer the period that you are observing, the better, okay? This line represents your actual condition, okay?
13:01:840Michele De Carli: But let's, like, let's consider that this is, as a first, first rough approximation, sorry. Okay, let's consider that this is the
13:10:280Michele De Carli: way we can address the power, which can be emitted by a building, okay, in a certain moment, okay? And we realize it, okay?
13:22:770Michele De Carli: What?
13:25:360Michele De Carli: We can call this ratio Tector.
13:34:70Michele De Carli: So, the sector role is different.
13:37:310Michele De Carli: And the percentage of needed power in a certain moment with respect to the design. The design power is the maximum power that we need.
13:46:680Michele De Carli: Okay?
13:47:920Michele De Carli: And this is, of course.
13:50:210Michele De Carli: from 0 to 1, or in percentage, okay? So, when I say that today… well, today we are off of hitting people, I say.
14:02:440Michele De Carli: Let's consider that today we have maybe 10 degrees C, okay? And let's consider that we have an average temperature, so we can say that today we have
14:14:90Michele De Carli: Okay, 50% of factor loaded, okay, in this comment. So that means that through this moment, we need half of the power, which is, okay, we suppose, in design solutions, right?
14:27:600Michele De Carli: Alright, so now… We can see that we can,
14:33:160Michele De Carli: Instead of putting the power here, we can…
14:37:390Michele De Carli: You can, right, okay, I will, I will do the, the, the sketches. I will add some, some slides.
14:52:710Michele De Carli: Okay.
15:07:400Michele De Carli: Okay, so…
15:12:100Michele De Carli: We have the factor load, Oh, let's load faster, okay?
15:17:790Michele De Carli: Photoretical counter load factor, so… Not that, okay? English.
15:26:230Michele De Carli: Lone fracture, From 0 to 100%, okay.
15:33:60Michele De Carli: And this is the linear correlation between 0 and 0.
15:36:670Michele De Carli: 12 degrees, okay?
15:40:00Michele De Carli: Alright. So, the root factor is the extra, divided by Dave the Sun.
15:53:890Michele De Carli: Right?
15:56:220Michele De Carli: But you can also… You can also say.
15:59:910Michele De Carli: You can see here, based on these equations, that the load factor is also
16:10:130Michele De Carli: The law factor, which can be released by the regulator, okay?
16:16:780Michele De Carli: Can be, can be… Can be…
16:22:600Michele De Carli: Written in an exponential way, okay.
16:27:190Michele De Carli: So, it means that, basically, We could consider that the
16:37:800Michele De Carli: Let's write here before the water temperature of the radiator, the average, okay, we can consider… let's imagine, okay, that the load factor, so we need… we could reach 100% of the power delivered by the radiator, okay.
16:56:640Michele De Carli: According to the…
16:59:530Michele De Carli: to a temperature of 50 degrees C, 70 degrees C, in other words, average water temperature, it means 70 minus 20, 50 degrees.
17:10:160Michele De Carli: Right?
17:11:710Michele De Carli: Okay?
17:13:819Michele De Carli: I mean, let's consider that,
17:17:210Michele De Carli: In this case, okay, let's consider that
17:21:930Michele De Carli: We don't know anything about these derivators, but we can assume, okay, that these derivators are… or have been designed for a temperature of a temperature of 70 degrees as, let's say, average temperature nanometers.
17:37:310Michele De Carli: Now, what happens is that, of course, we have an explanation function, which is 10,
17:44:140Michele De Carli: And we can say that by changing the
17:48:870Michele De Carli: Temperature of the water, okay, inside.
17:52:810Michele De Carli: Okay, because this is the question, and you can do it on Zoom Excel. It's very simple.
17:58:290Michele De Carli: Okay, we can say that,
18:00:890Michele De Carli: the… according to the auto… to the… sorry, to the… to the supply temperature of the water, okay, we can… we can have a load factor which is… which is variable as a function of the water temperature that we have, on average, in the… in the… in the… in the radiator.
18:19:860Michele De Carli: Okay So, this is… The design conditions, and this is… these are the design conditions.
18:28:720Michele De Carli: When we have zero, Okay, we can say it if we have to add to this.
18:33:650Michele De Carli: So, actually, what we can say is that Deep!
18:39:400Michele De Carli: Or we could, in principle, buy…
18:42:800Michele De Carli: by working at different temperatures of the water in the radiator, we can adjust the required power of, let's say, the delivered power by the radiator. Okay, so the thermal output of the radiator is a function of the average water temperature with an exponential factor.
19:01:740Michele De Carli: At the same time, the low rebuilding is a function of the outcome.
19:07:420Michele De Carli: Okay?
19:08:660Michele De Carli: So, we… and of course, it is the same if we consider the Water temperature, or T.
19:17:430Michele De Carli: The difference between the water.
19:19:720Michele De Carli: Temperature, and the indoor temperature, the air temperature.
19:24:130Michele De Carli: Okay?
19:25:200Michele De Carli: Sure.
19:26:220Michele De Carli: Whatever we use here, either the water temperature or the delta, okay.
19:33:70Michele De Carli: We can have this exponential function.
19:37:100Michele De Carli: So… We can try to combine them, so we can try to see Okay? Bye, let's see…
19:45:250Michele De Carli: 30, okay, so with an iterative process, we can… Of course, sorry.
19:53:350Michele De Carli: That depends on N.
19:55:450Michele De Carli: Okay, so it depends on the type of derivative, but let's consider that it is 1.2, okay, as
20:01:520Michele De Carli: as coefficient of A.
20:04:420Michele De Carli: So, what we can say… what we could do, we can try to set the water temperature according to outer temperature. So, it means that, basically, when the
20:16:850Michele De Carli: Outer temperature is… Memo?
20:20:290Michele De Carli: we will have the maximum water temperature, and when the outdoor temperature is fairly easy, then we can switch off the heating system, and we can supply water at 15 degrees C, or 10 degrees, at room temperature, let's say, at room temperature.
20:40:170Michele De Carli: So, what we can do is actually this. Okay, so here you see, this is the, schematics, okay, of a…
20:51:550Michele De Carli: of what I just mentioned. Okay, so here we have the load factor with respect to delta air.
21:00:610Michele De Carli: Temperature? Of course. And, this is the, the, the… they…
21:08:180Michele De Carli: The temperature difference between the water and the room, okay.
21:14:330Michele De Carli: According to the… or considering, okay, assuming that the nominal power Oh, very good.
21:23:700Michele De Carli: is rich at today, This is the condition, okay, this is minus 6, okay, that's a change.
21:30:760Michele De Carli: So we can try to… or we can…
21:33:660Michele De Carli: define a function, linear function, exponential function, or any type, whatever you like, okay? Linear function could be enough, okay?
21:43:730Michele De Carli: In order to, let's say, associate the water temperature in radiator.
21:50:360Michele De Carli: As a function of the… Sorry, yeah, the outcome of the radar as a function of the outcome.
21:57:670Michele De Carli: Okay?
21:59:500Michele De Carli: Here's a KN and KN.
22:03:870Michele De Carli: or somewhere. K, as you like.
22:07:880Michele De Carli: It doesn't matter, it's a constant. So, constant to get a bit about, okay?
22:14:30Michele De Carli: Okay.
22:16:160Michele De Carli: So, we… you can see here, by… back by,
22:24:220Michele De Carli: Assuming a circle, also even a Lion function, okay, between the outer temperature and the water temperature, okay, you can see that there is a small change, okay, but it's not bad.
22:37:610Michele De Carli: Okay? La tragolant, okay?
22:39:900Michele De Carli: Of course, this assumption He's falling, okay, a little bit in…
22:47:960Michele De Carli: In effect, when you have outdoor conditions, okay, with relative high temperature, okay, so mild conditions, mid-seasons.
22:59:690Michele De Carli: and sunny, solar, and sunny.
23:03:600Michele De Carli: Days, okay, because if we were not considering the effect of solar radiation, okay, and that, of course, can
23:10:800Michele De Carli: But in principle, we can't use that.
23:14:660Michele De Carli: Okay?
23:15:800Michele De Carli: So, we can say that, basically, Baal
23:19:70Michele De Carli: By, by, supplying the water temperature in the radiators according to the order temperature, so reducing the water supply
23:31:570Michele De Carli: of our heating.
23:33:800Michele De Carli: seaside, right?
23:36:90Michele De Carli: From the generator to the news, okay?
23:40:450Michele De Carli: When… so if we reduce the temperature, when the outer temperature increases, we have a kind of self
23:49:520Michele De Carli: Regulation of the predictors, okay?
23:53:170Michele De Carli: Which is, of course, important, okay? And that is what you usually do. It's called, climatic, okay, cultural strategy, okay? And this is usually done
24:05:270Michele De Carli: For, let's say, saving energy, because you can rely, okay, do work, on this self-regulation that the
24:17:550Michele De Carli: thermal output given by the radiator has according to the water temperature. So, when we need less power, then we reduce the water
24:30:290Michele De Carli: temperature supply in the radiator, the water supply temperature reduced… will reduce also the average temperature of the radiator, of course, and then the radiator will release less thermal output than needed, okay?
24:46:700Michele De Carli: very much, probably, according to the designer law. Of course,
24:54:880Michele De Carli: This is the, let's say, the, the chromatic strike, climatic
24:59:690Michele De Carli: control strategy, okay? And to do that, you usually do that. Why? Because, of course, on one hand, there is a self-regulation, okay?
25:13:100Michele De Carli: So, here you have two possibilities. Either you are controlling the room temperature in the thermostat, okay, room temperature, or given by the thermostat's gauge, okay, thermostat gauge.
25:26:750Michele De Carli: R?
25:27:900Michele De Carli: Like here, for instance, you can see, you're dumped.
25:31:920Michele De Carli: You don't regulate advocates, okay?
25:34:700Michele De Carli: This is… You know… So,
25:41:980Michele De Carli: Well, in case you don't control the temperature, in that case, you would anyway, avoid extra, okay, heating of the inhibitors, okay? So.
25:54:690Michele De Carli: But, on the other hand, of course, it is also a question of efficiency. So, along the season.
26:03:170Michele De Carli: If you reduce the supply temperature, okay.
26:08:20Michele De Carli: If you work with condensing boilers, you can work always in condensation, or most of the time in condensation, okay? So, with high efficiency of the boiler, but it's much more relevant for the heat pumps, okay? So, if you have a heat pump.
26:23:450Michele De Carli: Then, of course, the… the greater the… the… the greater the… the greater the… sorry, the… yes, the greater the supply temperature, the greater will be the condensing temperature, the lower will be the super, okay? But…
26:39:350Michele De Carli: if it's not needed to go at a certain level, you can reduce it according to the outer temperature, okay? So, in that case, you can have better COP, especially at partial modes, okay? Yes.
26:53:810Michele De Carli: But the classic thermostat, it opens and closes the absence of the radiator. How do we link it up onto the classic generator in order to modify the thermostat is, is, is, is, connected to the…
27:10:880Michele De Carli: to the banda, the civic of this zone, and usually it closes the sequence of the zone. By closing the sequence of the zone.
27:19:280Michele De Carli: If there is one pump circulation, the water temperature in the primary loop will increase, and when it reaches a certain level, okay, then the water will stop. It will stop.
27:32:50Michele De Carli: Okay, we will… we will look at some control strategies on the, on the… Generational systems, okay?
27:40:250Michele De Carli: All right, so we can say that basically this is a very, a very interesting solution, okay, for, let's say, for both control strategy and for the efficiency in the generation of the heating.
27:55:760Michele De Carli: along… along the season, okay?
27:58:930Michele De Carli: Alright, so, that's all for admitos, okay? There is not so much to say, okay.
28:13:600Michele De Carli: Now, there are some, some other emission systems which are similar to the radiators, okay, so they are, let's say.
28:25:690Michele De Carli: They work on the same principle.
28:29:20Michele De Carli: the shape, I mean, they are different because, okay, the shape, as you can see here, they are different, okay?
28:35:530Michele De Carli: We have the thin tube. The thin tube is basically a, a, a pipe, okay, a tube where we have fin on, on the outer, on the outer shell of the pipe. And, you can see, usually they are placed on the, on the, on the…
28:55:480Michele De Carli: on the… on the floor, okay? And, actually, these are used, as I was telling you yesterday, okay? I was asked when do we use the radiator,
29:07:170Michele De Carli: On… with the sip it on the…
29:11:640Michele De Carli: on the floor, okay, this is what you could do, for instance, with… instead of a regulatory, you could install this, which is smaller.
29:23:190Michele De Carli: So, let's say that, originally they, they were used for even higher, delativity between water and, and, and,
29:37:10Michele De Carli: India, okay?
29:39:70Michele De Carli: And, this is the usual, okay, the usual, power which can be delivered, okay, according to the shape of the exchange. Let's say, okay, how many things, okay, so the distance of things, the large, the height of cylinder of things, and so forth, let's say.
29:57:410Michele De Carli: Between 360 and 6008.
30:01:410Michele De Carli: Of course, this was very much used also for, for instance, in, industrial buildings, okay, or greenhouses, cargo houses, okay? If you go in the, airport of Brussels, okay, have you ever been in the airport in Brussels? Have you been one of you?
30:20:900Michele De Carli: Nope.
30:21:590Michele De Carli: Okay, okay, when… And… So,
30:27:200Michele De Carli: Brooklyn. Brooksale, yeah. Yeah, okay, so when there is…
30:32:770Michele De Carli: There are some areas where there is, But you can…
30:37:450Michele De Carli: They're a little bit… it's a little bit suspended, okay, and if you look a little bit down, okay, you can see the spring tubes, okay, which are useful in…
30:46:340Michele De Carli: the, I think for, for, let's say, S oxide system, not really S.
30:53:650Michele De Carli: Because I think it's full air, but…
30:56:230Michele De Carli: Since, as I told you, this is a very large placed building, okay, when there is
31:03:40Michele De Carli: When the outdoor conditions go, quite low, the temperature and heat, then these are used as, as, as oxidation, okay?
31:11:930Michele De Carli: Okay, and there is this…
31:16:180Michele De Carli: Okay, this is, the baseball hitting, okay, but it's compa radiant, okay, so the radiant baseball, okay.
31:25:620Michele De Carli: it's not that old, radiant, okay? Okay, it's radiant, but it's also conducting, okay? So this is, became very famous in the 90s, okay, when it first proposed that it was a quite,
31:41:630Michele De Carli: disruptive, like, technology, okay, especially for…
31:44:850Michele De Carli: for historical buildings, I mean, actually, it might be an interesting solution, okay, because you can see you can put that without breaking too much, okay, with oils and so on, or you can… you can… you can use that for later people, for instance, when you have… when you have some…
32:01:990Michele De Carli: some, you don't want to really, work that much on the wars and so on. Okay, and what I would like to show you is that that's basically, okay.
32:12:340Michele De Carli: This is… what is this? Sorry, this is the thin… so you can see there are thin, there are aluminum, sorry, copper pipes with aluminum fins, okay, so actually it's a thin coil. And, you can see…
32:27:720Michele De Carli: Here, okay. Of course, they are put on the, on the bottom of the, of the rules, okay? And, I would like to highlight here, well.
32:38:120Michele De Carli: I would like to highlight, for instance, that if you have
32:41:190Michele De Carli: For instance, 80 degrees C, okay, as temperature of the sun.
32:47:790Michele De Carli: Water supply, which means
32:50:470Michele De Carli: let's consider, let's say, 70 degrees C, okay, which, has average temperature of whatever it is. You can see that we have 200, 200, between 250 and 300 watts per minute, which is okay.
33:09:350Michele De Carli: If we go… sorry, if we use a supply temperature here, okay.
33:15:100Michele De Carli: So, when we have more or less an average temperature of 80, okay, we can see that we have… we reached 300 watts, okay, per liter, which is more or less similar to this one. Okay, so actually, this is a feed tube. So, the baseball heating, okay, is, especially here in Italy, is usually
33:34:260Michele De Carli: named, the radiant baseball. It's not a radiant, but it is, of course, works on radiant, but it mainly works on convection, okay?
33:43:330Michele De Carli: And, and, it is, okay, not really… I mean, it's a usual way… I mean, it's another… it's a new way to dress the thinking, okay? So that is how it is. I don't say that it's not, I mean, it's not garbage, okay, that's the technology.
34:01:700Michele De Carli: It might be used, but it's not an address that this actually means. It's an old technology, which has been known since an old time, but with a different address, okay?
34:12:449Michele De Carli: Mmm… okay.
34:16:449Michele De Carli: Oops, there was a… I know that there was a…
34:21:659Michele De Carli: One producer who was, who was,
34:27:20Michele De Carli: Who's proposing leasing, I don't remember exactly.
34:29:900Michele De Carli: Wendy, 19 years ago.
34:32:70Michele De Carli: Yes.
34:33:80Michele De Carli: Sorry, I was talking like that, so every time I look at this picture, I always remember the way he walked, and he talked, and I usually laugh, okay? So…
34:44:670Michele De Carli: Alright, so then this is the other technology, okay, that, we could, have in many existing buildings. It's, similar, okay, it's a so-called convector heating system.
35:01:800Michele De Carli: The conductivity systems, they, they are, they, they are, they will, okay, so they are not used anymore, okay, or not in this, in this, kind of system. They work also, I mean, all these technologies are working with lateral conduction, okay? So, with lateral conduction, it means that, basically.
35:21:190Michele De Carli: there was a case, okay, usually a case in a medical case, where you had this film, this filmed,
35:29:640Michele De Carli: The coil, okay, in the side.
35:32:380Michele De Carli: It was mainly used, especially if you had,
35:37:810Michele De Carli: not vapor, but vapor or, pressurized water, okay? So, so with high temperatures, which could lead to small surfaces, okay?
35:51:520Michele De Carli: And I mean, there are not really in particular, okay? They are… they were working with the natural complexion, okay? You can have them.
36:02:950Michele De Carli: Also, you can, summon them to the seed, and also this can be used also as, as, auxiliary system in, cold ground, that's okay. On the, on the…
36:19:380Michele De Carli: on the edge of the building, okay, so we can see here, yeah, they said, okay? And, basically, they are auxiliary systems, which can be used, together with the system, okay, which is…
36:39:460Michele De Carli: But there is not so much to say, okay?
36:44:600Michele De Carli: Yes, usually they work with very high temperature, and no less, that is, okay? The pro was that they were cheaper than the others.
36:56:130Michele De Carli: It goes on the, complexness of this, artificial.
37:01:310Michele De Carli: I remember I lived for one year in a flat, where there was this landed fitting system, okay, and
37:12:00Michele De Carli: in the center of the Often, okay? So close to the… comprato de la, okay?
37:20:580Michele De Carli: Okay, so, that's all for, not for today, but for this part, okay? So, we have seen that basically all these solutions are natural.
37:32:540Michele De Carli: convective, they're working on mechanical convection, okay? And they are, say, just for heating, okay? And now, what we are going to see is, the, what we are going to see are technologies which instead work on force ventilation, okay?
37:50:160Michele De Carli: And that can be used for heating and cooling, and I will open right now the presentation.
37:57:890Michele De Carli: Internal book.
