00:00:00Okay. Ora so now we are going to talk about it and we are going
00:00:11as you we are going to look in particular at
00:00:16the resource air one side of the air one,
00:00:23but because we have been to save the ground changes in the.
00:00:31New energy technology.
00:00:34Okay, so make a brief,
00:00:38okay recap of the just to make you weather overview,
00:00:44okay and to keep it will
00:00:47assume that you know how everything okay a many of you
00:00:51are engineers and we did not so it's food
00:00:56for you make Works.
00:01:06Ok. So what is a Okay,
00:01:13so basically is making which is transforming Ok.
00:01:20The it is moving it from the source to e out.
00:01:30Due Ok, ok. And in order to to do that ok,
00:01:37you have the electricity he spent in
00:01:42e complesso in in in versante ok he
00:01:48so basically ok. You have to consider di he temperature need to
00:01:58Quindi è incisivo il supply delivery with
00:02:04the mission systems and the other side you have
00:02:09the consider the source and sources.
00:02:15Ok, so e so che io
00:02:19so pazzo e resource exchanges
00:02:23so closed loops in background with the vertical solution.
00:02:28Okay, so you could take some below the ground,
00:02:33ok and then you could.
00:02:36In principal works with flakes.
00:02:39Ok. Sì, o lagoon,
00:02:41what you can from other?
00:02:48He was water?
00:02:51Ok. Ok. or any other solution.
00:03:00Of course could also use
00:03:03the terma thermal resources
00:03:07is now in he is going to in Montegrotto.
00:03:14Construction district network on the water waste from the space.
00:03:23Ok. Ehm, ok.
00:03:27So these are the different opportunities that you
00:03:30have so one side you have to consider.
00:03:33Le temperature that you need to use in the house in the building.
00:03:41Of the use which is then
00:03:44affettive con temperature and on the other side of the source,
00:03:49which is affected evaporati.
00:03:53The great Temperature difference between
00:03:57del complesso between
00:04:00e evaporazione del source evaporazione temperature
00:04:04and user inside con temperature be will be
00:04:10the power unit to spend Ok. For for the.
00:04:21Day from the lower temperature source to the other side.
00:04:29He. So this is love sei general.
00:04:42Average conditions conditions optimal considera
00:04:48for the different different sources Ok,
00:04:54so on the top of the bottom of the of
00:05:00the end of the other slide,
00:05:07we have the different qualitative.
00:05:12He on the top of the he of the end of the slide.
00:05:23We can si sa leggere temperature that we can use inside
00:05:29the buildings ok to github for the different kit in progress.
00:05:36Let's start with with this ok sole with this of course.
00:05:43We could use temperature a soli 15 instance.
00:05:52We want to insider
00:05:56existing distribution network is the usually the usual.
00:06:02Aperture di crisi?
00:06:04Sì, Ehm.
00:06:13Ehm.
00:06:17You at lower five with the Francois,
00:06:24or you can work
00:06:27even lower time to work in system and and you should.
00:06:37So of course to think about the levels of
00:06:41temperature ok of the supply temperature.
00:06:44They are related to the age of
00:06:48your end of the other side
00:06:51you have to articoli determinano le sources
00:06:54have you should have been de de de de de
00:07:01think so if you have the water of about us,
00:07:11if you were in wild recovery from.
00:07:17Water or you can have to see more Ok,
00:07:22if you work with the ground it exchanges, you can consider.
00:07:29Conditions ground it to work with the same seven.
00:07:36Nel seguito alcune sì and in case ok Ivan ok,
00:07:44as is this is the year with this solution,
00:07:50che So you can work with the temperature Ok on
00:07:55this which is very good and on the other side.
00:08:01You have the author,
00:08:03which is to the grace,
00:08:05of course you can see that the best
00:08:10to the conditions of the source, but.
00:08:17Not as the world,
00:08:21which is the heart source, which is working.
00:08:25Sources, but of course extremely because this
00:08:32is very easy to the rules and to do.
00:08:37Visto? Ok. Ehm.
00:08:41Okay. Of course.
00:08:43Okay. That's that's it.
00:08:46Ehm, okay.
00:08:48So this is what you che considera.
00:08:52Santos in the machine one and you have the the source
00:09:01with e ok and inside machine Ok the evaporazione temperature.
00:09:14Evaporati in temperature will be smaller temperature of
00:09:19the source because you have absolute dei source.
00:09:25You need to be need to have below the other side.
00:09:33So you also use electric energy for the compressor to pump dei set
00:09:42up and you condensate
00:09:47e sempre più condensa with
00:09:48the Detta which is better than the water.
00:09:52Temperature in abiti ok. Ehm.
00:10:01In case what we are interested
00:10:05in is the it that we are delivery into
00:10:08the building so the efficiency is is defined.
00:10:18Which is between the energy,
00:10:22which is delivery to the.
00:10:25Power talking about the design conditions ok or
00:10:30conditions de de de de de de de de man of
00:10:37the building building by the electric the man of the compression.
00:10:43Ok. So pending on
00:10:48the difference difference and
00:10:53the congresso should work more to drive or to face the discussion.
00:10:59Ok, ehm. Ora so,
00:11:05dissi stessi hop on the other side, of course.
00:11:08The positive point of the technology is that you can cool.
00:11:17You can work with the same cycle by the.
00:11:23Way he you can work with the same machine,
00:11:31but in coming out in this case.
00:11:35The machine is the same always in this is the evaporate is
00:11:45the he is he absolute
00:11:49the heat in the building so decoupling demand ok
00:11:54and in this case in case the evaporazione temperature will be
00:11:58below the water temperature that is in the.
00:12:04End of the other side you will he you will reject.
00:12:11De de de de cooling plus
00:12:16the compression de de de de de electric demand compression.
00:12:23Ok, tu de condensa which will be greater temperature then
00:12:28de de okay hem head of course.
00:12:36We are interested in how much cool,
00:12:40we are on the building.
00:12:43Ok. Hem sono Ehm.
00:12:49In this is the question are
00:12:54energy efficiency KEE which is the energy.
00:13:01Demand required by the compresso so basic systems.
00:13:08There are working for the could be.
00:13:12So easy day system in the building divided by the elettricità.
00:13:19Nel complesso the current this is able
00:13:23to be this is the end,
00:13:29of course in the world.
00:13:30Qui ecco conditions equal or in e large time frame ok in
00:13:40what is important to remember is that any case
00:13:45Whatever it is the end of.
00:13:51The hem de energy or the power which is delivered in the in
00:13:59the content is the energy of power that
00:14:03is in the vapore and vapore plus the energy of power.
00:14:10Confesso che.
00:14:14Sono eh?
00:14:18This is the show the KEE,
00:14:24we will talk many or just about
00:14:28the air the water it exchange so we are
00:14:33going to talk about this kind of the crisis
00:14:37where are evaporate in with so we have.
00:14:45And we are we are dealing with which is absolute in trace.
00:14:56And which is that is at lower east.
00:15:04And in the other case.
00:15:08We have the.
00:15:11Degenerato is produced to the building.
00:15:15Ok he in we are the heat in the outdoor we are.
00:15:26Outdoor and we are killing the water ok for the different.
00:15:33Ok. Ok. Ok. So what is,
00:15:41of course de main point think
00:15:45about when we consider the heart when we have to
00:15:50think about a will go again on this he he he he,
00:16:00of course you dipende in on the level of
00:16:03temperature that using the building your
00:16:07going to film about he we can supply water.
00:16:14Okay. Le sei date in principle up
00:16:18to le sei minus five minus Chrissy,
00:16:22le sei minus di Chris che we can steel work with degrees inside.
00:16:31Out of course will be okay the best would be to work at smaller.
00:16:40Temperature Eh, ma tu consider what kind of emission system?
00:16:48We have been existing building or buildings
00:16:53and so if you are free to the sandwich kind of emissions.
00:16:58We have or if you have to keep the mission.
00:17:03This on the second point is that in any case.
00:17:08Building you will have to produce domestico total in case.
00:17:14You are the think that you need on the other side to
00:17:18size e thank ok in order to produce
00:17:24the moment of the design dei conditions
00:17:30and and of course the water level is the week end,
00:17:38he Consider the maximum amount emission system and the domestic.
00:17:47In ogni caso, what happens when we talk about the?
00:17:56Source when we talk about.
00:18:00The pending on the hem on
00:18:06the he temperature difference
00:18:09between the temperature and the supply temperature ok,
00:18:14you can see that you have e di crisis in the city.
00:18:20Ok. Ehm so it means that basically
00:18:25you can work with as you can see you can working.
00:18:32But that on this a maggior leverage with.
00:18:38Così tanti che è possibile e opportuno.
00:18:42Okay. Eh?
00:18:51So if you have so when you have
00:18:55this when you are
00:18:58here you are here If you have an outdoor temperature of.
00:19:05End e weather terriccio.
00:19:09Oh sì, ok.
00:19:13So basically dissi.
00:19:16You can il radiatore in the same conditions,
00:19:21but radiatore should be sud.
00:19:25Should be supply by pass maximum.
00:19:33Or you can work with franco unit Ok,
00:19:38so che ti fidi.
00:19:39Sì, ok. And I
00:19:44can also maybe he worldwide e Francoise Walker,
00:19:51but the year to.
00:19:55Minus five. Ah, che so,
00:19:59è che mi serve?
00:20:02Dai, facciamo.
00:20:04Okay. Okay. And you can?
00:20:11For instance if you have fan coglioni.
00:20:14Tu che fai? Forti fidi.
00:20:16Crisi e supply Ok.
00:20:20And made in corso think about using domestic.
00:20:29Okay, so i dissensi più forti.
00:20:33Sì, sì, ok. Sixty di crisi o se ti fai di crisi.
00:20:39IT means that you can go with
00:20:41the outdoor temperature down tu minus.
00:20:46So the you can expand the operation of the air.
00:20:52You are the supply, of course,
00:20:57then you have to know how to do that the he domestico tutto ok,
00:21:04ma in principle you can can e sei mesi proprio da minus.
00:21:18Of course. We ok, eh?
00:21:26We are talking about design condition very.
00:21:31We are most of the time working with Faccia al caso nostro.
00:21:38Time remember you can you will?
00:21:46Be about the design conditions and the same time if you working or
00:21:53with regard systems can you can also be review on the supply side.
00:22:01You can consider that may be on average work.
00:22:06Maybe so what is the week is the temperature,
00:22:13you can work on average in order to
00:22:17have the kind of season Performance factor.
00:22:21Okay season performance una performance factor
00:22:26is season ok back to the building.
00:22:32Ok. Gli dissi What you can that we
00:22:37can you can see that di decreased have to
00:22:41one point of people want to have
00:22:46to have to one point to point greater.
00:22:52But of course as we have been it needs more cost because this
00:22:57need about this is it is dreaming.
00:23:02Ok, mi ci vuole il power of the time.
00:23:06Ok ora ok.
00:23:10Anyway. Ehm. Ok, that's that's all.
00:23:19Ehm, no, that's but let's that this is what you can we can am.
00:23:30Yes on the other side O che so io
00:23:34più che mai di reasonable or not to main issues in the first issue
00:23:41is the cost of electricity compare to
00:23:44natural gas if the if the chi nuotava of
00:23:50thermal che chi produce costs less relativi
00:23:54less in event of the wind still
00:24:00convenient e many case You should
00:24:05consider average cop in order to have an idea of the build that
00:24:10you can get from the way of the second point
00:24:14is how much renewable energy you have on
00:24:19the national mix on
00:24:23the renewable percent of
00:24:27renewable energy that you have in he when you were.
00:24:32Qui. Il may be even more reasonable to work with the two.
00:24:39Ok. Ehm.
00:24:42So di imaging that you are where
00:24:46the mission is it when you were with electricity.
00:24:52E tu will be not comparable
00:24:56with natural gas because Maybe is not but this must be
00:25:00which is one so so keeping that country different ok
00:25:09different Le sei boundary conditions on
00:25:14the efficiency or effectiveness of the solution.
00:25:20Ok. A Italy.
00:25:26Okay. I think.
00:25:29E bought with new or with existing buildings.
00:25:38Boh. Boh. Ok, new buildings that.
00:25:42Because this is.
00:25:45Not only because this must because this keeper.
00:25:49With the old keep calm and the point.
00:25:56Some. And what we are we are directly jumping into the.
00:26:04Ok. Ok, ok.
00:26:13So what is the effect of the outdoor.
00:26:18Temperature Ok on the day is Ok.
00:26:24Death by the temperature Ok, of course.
00:26:32The shop Ok.
00:26:35Even if you if if you at constant
00:26:39inside of supply sorry if you decrease
00:26:44the outdoor temperature ok. De de de de de negative point of
00:26:52it is it when you decreased
00:26:56the outdoor temperature as we have been in
00:26:59renewable energy course we can.
00:27:03Also the generation cheating of
00:27:11the death generated by the it is the capacity,
00:27:18which can be provided it capacity
00:27:22that can be provided by the it will lower with outdoor.
00:27:27Temperature. Ok. So I
00:27:33need to possibili cause We need to consider that
00:27:36the same design conditions they.
00:27:41Were as we have already
00:27:45seen we need to consider that we have that the green curves.
00:27:52Here is the power,
00:27:55which can be by on the other side.
00:27:58We have the opposite trend ok of the Lord of the buildings.
00:28:06Okay, because this is a was man in the beginning of
00:28:10the section KEE that the witcher consider
00:28:15that the power of the actual power needed by the building is
00:28:23the place of the times the temperature between inside outside.
00:28:33Okay, so we have linear relationship in find.
00:28:42He he.
00:28:48He. Skin KEE linear relationship
00:28:57where the end of the building is.
00:29:01When the outdoor crisis and we have our design conditions here.
00:29:11Okay end della side we have that it is able to deliver
00:29:17e power which is smaller which is
00:29:20the cruising when the outdoor temperature decreased.
00:29:25We have to match this to different one and we
00:29:29have the energy demand and the building which is.
00:29:34Increase by the.
00:29:40Thermal switch can be deliver by which is the crisis.
00:29:46Which is the matching between
00:29:49this two curves defense is that we have Ok, of course.
00:29:58He we can in principal size the.
00:30:06Principal select the epub is Ok he is the.
00:30:15Minimum end in minimum design conditions
00:30:21Ok we have corso del minimum power del verbale,
00:30:27che so, le sei del World War System e della dietro MB.
00:30:37Forse for the domestic, ok.
00:30:41He we can okay work we have been that.
00:30:47We still. Work di King?
00:30:54Mi pare di sì, Anzi no, okay.
00:30:59This can be today down by the times.
00:31:04Ok. E solo in
00:31:10design condition ormai diversi più che worldwide, difatti.
00:31:22I difensori On the power to think about
00:31:28the question of power thermal power of the electric power,
00:31:33which is needed for the power.
00:31:36Of. The house some additional electric power
00:31:45for appliance lighting and son.
00:31:47Ok. Ok, ok, so you need to consider much feeling in the house.
00:31:56Ok. Ok, so in principal you can do that.
00:32:08Welcome to this point at the end of the one direction.
00:32:12This is what is required by you for your house.
00:32:17Okay, so this is how you should select then dell'impatto
00:32:21che questi so basically just in time Preview.
00:32:28Ehm ehm no ehm spoiler eh?
00:32:35Gli altri Not only the power for you need to see the power for
00:32:40domestico and we have to the brain he Delle cose che.
00:32:51Sono in general.
00:32:53Okay. You can he tu consideri the crossing?
00:32:57Ho visto che so we have been in the previous KEE that you can world
00:33:06wide e with full film full film the eating the power key.
00:33:18But may be okay I maghi
00:33:23Not the optimal solution key for your building and
00:33:29maybe you can stop ok you can
00:33:34select the size of the not a design at the design.
00:33:40Oh, sorry, but.
00:33:45The truth which is the design terrace. Okay.
00:34:02Il fatto che adesso.
00:34:05You have we will see how to choose between one or
00:34:09another ok and that
00:34:14okay in in in we want to see
00:34:20you how to do that it will give you some it
00:34:24say input for the signing one or another Okay,
00:34:28so let's start with we will see for we will see for you.
00:34:37There are for possibility to say e he resource in case
00:34:43the best scenario is if you have e
00:34:48new building a New York building building.
00:34:54Okay, eh?
00:34:57The day you can in principal work with.
00:35:05E intanto which is the maximum power at the design,
00:35:10che so if you are new building.
00:35:13Ok, let's make just very.
00:35:21How much power you need for a new building.
00:35:25Per volume Building.
00:35:30Works. Let's imaging to help one of house presso small single
00:35:41e. Let's considera in
00:35:45annunci sesso gay e like it.
00:35:53Will not. Not so, ma.
00:36:03Anche tu andresti.
00:36:07Tu three three per Android volume Right
00:36:18Ok if we dai tempi di Six Kilowatt okay off per l'energy
00:36:29e. Let's
00:36:38make a very conservative.
00:36:42Ok? Of course.
00:36:44We will let's consider that
00:36:47you let's consider che sia opportuno x tutti noi.
00:37:01Kilowatt of peak for electricity.
00:37:06Is this affordable.
00:37:10Much it Cristiani.
00:37:15Ok. Di gas?
00:37:21No, forse.
00:37:25No.
00:37:28Ok, ora so tre.
00:37:31Ok, ok. You can eat for point five or guarda caso
00:37:38even triclosan electric pig for the he for the God is not so.
00:37:50IT.
00:37:53Ok. If you are here if you are leaving for you go with the because.
00:38:03I don't know what you will have.
00:38:08You you have you.
00:38:11If if you are able to to to build up to the house,
00:38:15then for you will have everything reading.
00:38:19Si scrivono che i can you are
00:38:22some where the want to install the green song.
00:38:30Lux as light in the house of the spend. A led.
00:38:38Enzo Ok, è Jobs act is not also if you have to have the.
00:38:46Power. Ok. Ok.
00:38:54But we don't we don't said in audio.
00:39:00Ok. He so what
00:39:05I want to mention is three kilowatt of electricity is.
00:39:10So even if you so just mention even if you
00:39:16have internet of flat twenty works.
00:39:24Which means three hundred of olio ok deck will lead to six kg.
00:39:36Power which is again.
00:39:39Sono lettrice e so from the electrical point of view.
00:39:44It's not a big problem ok to the world.
00:39:49Il boss for a New Delhi La City Archive.
00:39:56If you are not flight o che.
00:40:02So io avessi un candidato,
00:40:08penso, perché è andato via.
00:40:11Ma allora Però qua no.
00:40:16Ah, ecco. Ok. Ehm.
00:40:19So solo in principal you have to make some analysis.
00:40:27Ok? If you are able to compensate at the design to check,
00:40:34which is the power of the time at the ok
00:40:39and you have to the power needed.
00:40:45Ok. We are the cost to to be electric power.
00:40:53Ok. He and the electric power in genere Ok.
00:40:58So i più Ok. You will check is
00:41:04this time that you should go in this direction should.
00:41:10Forse in the maximum peak Load in Design Condition Ben
00:41:17ok. What happens baby?
00:41:20Ok for different reasons
00:41:24Ok Maybe it's not to work at design conditions.
00:41:32Ok. Eh, sai tu eh?
00:41:38Tu sei er trippando et design.
00:41:43Temperature che so you cud
00:41:45consider to work with an intermediate temperature.
00:41:49Ok, so what you could do you could consider to
00:41:55work ed è tutto ok. Eh, sai.
00:42:04Ok, on the outdoor conditions so there are
00:42:11different possibility responsibility in iter with the above the.
00:42:20Way. Or with the boiler Ok,
00:42:27so in this case you have
00:42:29hybrid solution so solution where is to be set or size.
00:42:37Consiglieri di costo could.
00:42:42Have you are the Siding which is the cat of
00:42:46temperature Ok now could be for
00:42:51one too big to you may you have the power which is delivered this.
00:43:01Tutto ok and this will be the science of your way.
00:43:08Ben we will have he e e e e boiler ok.
00:43:14Which is then feeding the building.
00:43:19E tu ti sbagli, okay?
00:43:25Ehm, so io mi difendo on the supply.
00:43:31Side of the shop that you have because may be
00:43:35b keeper to work with che so io e non lo so.
00:43:41In Order to not oversize the keep it be the solution.
00:43:47Okay, so in this case, eh?
00:43:52You select day according to the cat.
00:43:58Is the temperature where the wild switch
00:44:02from the it was switch from the it to
00:44:05the natural solutions Hybrid solutions you by.
00:44:12You do you select
00:44:15e Sofa e e Prefabbricati solutions
00:44:23and or you can also built in time out.
00:44:31They should be okay omogeneo e switch.
00:44:37Ehm. Okay. In the future
00:44:45made it will be possible if you are split system unit to work with
00:44:50the system you will have controller it is
00:44:53switching from the split system unit Ok to the.
00:44:59Professor. Ok. Anyway, we
00:45:06have cut off Temperature che gli switch from to the Network.
00:45:13Non va okay?
00:45:16Eh sì, è possibile.
00:45:21E allora tu sei andato interested in it may be not middle of money,
00:45:30not may be not the need of cost of he of the natural gas.
00:45:37Okay. Because this might be anyway so i can work in
00:45:43any case I will size the okay to work in.
00:45:52With maximum power in this conditions.
00:45:56Ok. And then I work in parallel Ok so dimension in this case we
00:46:05talk about alternate working operational either
00:46:10with or with the bottom in this case.
00:46:15We work in parallelismo in this case solution KEE because.
00:46:23This case you work he
00:46:27everything and that it is
00:46:30not able to feed the supply temperature of your system.
00:46:34Then you will have an additional integration system like.
00:46:42This to use an electric resistance.
00:46:53Yes, no. Okay, so has been propos to use electric resistance,
00:46:59but usually ok it might be which is the design,
00:47:04but Usually even if you have shop on fire it to be much
00:47:11more than you are working with you can you can be resistance,
00:47:19but the original mining mining
00:47:25of the world resistance in principles.
00:47:33This is the parallel operations in this case
00:47:37this switch bivalente bivalente.
00:47:44That often ok cut off e bivalente
00:47:52with or he castri.
00:48:00Ok decade il face to work Otto size according to the end
00:48:10medi it may be reasonable to work steel key on
00:48:16the mod up to
00:48:19the end of the end to work with the body imaging like minus.
00:48:26Sì, ok. Sette fasi di crisi e di crisi che il mio
00:48:33to think about wide range of solution.
00:48:37Year some years it's not it's not don't consider ok as mandato.
00:48:46It's just mission work and you can you can work with in
00:48:56parallel operations equivalent temperature where the
00:49:01operation of the debole combina danni e cutoff,
00:49:08temperature ok e tempi intermedi validi.
00:49:11Quindi sì, ok, sono un boiler.
00:49:20Elettrico? Ok. Ok, so I think it was in for today, Ok.
00:49:30Welcome back and we will everything tomorrow. We go.
00:49:35Ok. Tomorrow and nice
00:49:41was the one of
00:49:43the last Wednesday evening that we have a student. Ok. So.
