00:00:00Claudia. Ok, ora so.
00:00:06Ora so now we are going to see the cooling system,
00:00:13especially large cooling plans.
00:00:16Okay, am I will not go into
00:00:22the death of all that I have uploaded because I want to.
00:00:30I want to have an idea Okay,
00:00:34so we want time to go deep bitter on
00:00:38this he on the all the slides Ok I will try to explain you.
00:00:44Are the typical architecture for
00:00:48large cooling ok and we are the main sei
00:00:53He philosophy in controlling the Eh eh eh.
00:01:03Last but not least ho corso, eh?
00:01:07What you should consider?
00:01:09He He in this is?
00:01:13Okay? Ehm, so Let's start.
00:01:19Okay? And.
00:01:23So. What?
00:01:30Eh? Ok. Ok.
00:01:36So what should be consider talk about?
00:01:40Ok. Ehm.
00:01:43As you by the way you need.
00:01:47To write with refrigerazione.
00:01:52Okay. Ehm. Ehm. When we talk about Colin Penso che.
00:02:03So which means that we we have refrigerante water exchange where.
00:02:11And we have the care about the potential freezing of the water.
00:02:19Okay, so the usual way to to manage the best way
00:02:28to manage the evaporazione Ok is to have
00:02:33a constant flow of the water in the vaporetto.
00:02:37Ok. Ehm.
00:02:40Eh. Ok. Ok, ok, lo so.
00:02:47This is what we need to consider is that the flow rate
00:02:52should be on one hand in order to have a link.
00:02:59E suitable difference between
00:03:02the water and refrigeranti in order to
00:03:05voice to the void solid formation on the other side.
00:03:11We need to meet the FLAURA2 he in sei we
00:03:17could not excited in the FLAURA2 in order to keep the drops.
00:03:23Ok, in limited caso that we have small pump in electricity he.
00:03:34He small. Ok, no,
00:03:43of course year we talk about large plants.
00:03:46Ok, so if you have e if you are working
00:03:50with just one and the killer is working with.
00:03:58By manufacturer Ok Ben the manufacturer
00:04:02can ok suggest ok to work today.
00:04:08This possible to have also variable speed variable pumps also in
00:04:14the same new deal with
00:04:18the he when you deal with large cooling plans.
00:04:23Ok he is the one way to see.
00:04:27You can work variable speed pumps.
00:04:32Usually the traditional day systems
00:04:39where the cost which ok,
00:04:45so hem of course,
00:04:49what we need to consider is how you
00:04:53can manage the Compilation che ho
00:04:58Hold on the production of
00:05:03the production side of the water end, of course.
00:05:09Eh ok.
00:05:12The usual way was to work with
00:05:15the wind low cost and on the city ok for the planet,
00:05:22we have to the types of architecture.
00:05:25Ok, so when we talk about
00:05:29the architects to the he tu consider.
00:05:37The primary sede primari e secondari.
00:05:42Ok, so we have.
00:05:44The hem de eh ok
00:05:51in tutto different types We have the distribution,
00:05:57which is working both on on on the primarie secondarie.
00:06:07IT ok and the Apple distribution
00:06:13where we have constant from
00:06:15primary circuit and variable flow on the second.
00:06:18Ok, ok, ora so let's have a look at the Apple distribution.
00:06:28Ok backup distribution we we have costant
00:06:33FLAURA2 on the primarie e secondarie seguito che so io Si.
00:06:38This is the primary circuit here,
00:06:40we have as you can see three killers in parallel ok
00:06:45and the killers using cold water.
00:06:50Ok, so the primary Circuit is this Ok. And
00:06:55then you you have the secondary circuit.
00:07:01Ok watch are providing.
00:07:06Ok. Sei.
00:07:10Tu. Non so che so.
00:07:13You are you have to where you produced
00:07:17the water and then the water then goes to
00:07:21the secondary circuit ok users of course here we have constant he
00:07:32ok. And we consider in
00:07:37the Apple distribution means that we use constant flow rate
00:07:41on the circuit and the secondary circuit.
00:07:44Ok, so by in order to have the constant FLAURA2 in the second.
00:07:54By changing the Lord of the terminal units.
00:07:59Ok, then we use e
00:08:02three way caso as we have seen when we talk about the the.
00:08:10The control strategy of the mission systems.
00:08:15We that we can variable speed or variable which means that we
00:08:20usually world wide web constant flow rate.
00:08:26Ok, so in this case,
00:08:29ok just to make what we can in this case.
00:08:34We have that the water can circolate either through
00:08:39the terminal system system or can bypass it ok
00:08:44and here we have because we have
00:08:47to enter the sections Sotto il letto.
00:08:50Ok, il set of the air ok which
00:08:55is the cross which sparso in through the emission system,
00:08:59ok and the world.
00:09:04Of the water blowing through the mission system.
00:09:09Ok, andiamo per tetti di bypass bypass the system,
00:09:15che so we have the mission system,
00:09:19ok. And then we can have
00:09:22a partial FLAURA2 into the mission system and then we have
00:09:27the way of the water ok of
00:09:31the end of the mission system of the time from the second city.
00:09:38Ok he so imagine water,
00:09:43ok, we have seven twelve.
00:09:46Ok, ok. Ehm nel
00:09:51we have water going out nine di Chris che.
00:09:56Because we have just working with a partial FLAURA2 and then
00:10:03we mix again the water with seven degrees as
00:10:07the supply line year of the second ADCs effect.
00:10:11We will mix ed.
00:10:15È tutto ok. E poi potevano offrire Ok, so.
00:10:29Ok, so what we have to think about is that we are produced water
00:10:38and we are when we have to think about how
00:10:44the system can work it partial operations E so when you have?
00:10:49He he he.
00:10:52E load factor which is below so in this case
00:10:58Okay the master rate will be constant ok in in.
00:11:06In this in the difference and you will bypass.
00:11:11Okay, so you will have three way in
00:11:15mixing mode on the return of the terminal limits.
00:11:20Ok, ok.
00:11:23So it means that if you
00:11:28have to load the water will pass all through
00:11:33the terminali Unix you have less than on
00:11:37load factor del will have
00:11:40partial bypass of the end of the terminal.
00:11:45Ok. Ben of course.
00:11:47The water FLAURA2 will will be the
00:11:50same in this case you will have Ok,
00:11:53then will be also constant.
00:11:58Ok in the killers ok,
00:12:03so now if the year is less than 100.
00:12:10Ok you will be good point.
00:12:13This is that we have always
00:12:16the same FLAURA2 to had in design conditions,
00:12:19che va ben al the killers che del should be the king
00:12:26of ehm syncro okay operations that the killer will work e design.
00:12:34Ok, so del killer should.
00:12:41Be will on work with the same faccia Non so that.
00:12:47Beh, eh.
00:12:54Ok. Good Ehm.
00:12:59In this picture here
00:13:03instead you have you have always capo distribution
00:13:08a working on the he on the primarie e secondarie.
00:13:17Sì, perché so the is exactly the same okay,
00:13:22you have every every terminal United.
00:13:25We have a bypass will make possible
00:13:29to have partial load operation okay by
00:13:34keeping the FLAURA2 in the year and in this case you have again
00:13:43Lettrici in parallelo KEE and day
00:13:47he and but in this case they have not one pump.
00:13:53Not in the previous.
00:13:57He sia the world
00:14:01constant and in this case they were working everyone with the same.
00:14:09Designs in this case you will have
00:14:13e he the pumps you have common okay and you will with different.
00:14:24You will have the killers.
00:14:27Okay, so in this case what you you see is that the year are you can
00:14:37just with the pump is working at constant floor light and in
00:14:45this case what you should
00:14:50do you should you could be purchased killer?
00:14:56Ok, ok. Ehm.
00:15:00In this case What do
00:15:03what is the what could be the problem of this solution?
00:15:07Okay problem di solution to have common pump in the
00:15:11for the killers che you can see the year of this is the same.
00:15:17Che consiglio a tutti Tu,
00:15:19Gilles KEE in this case you can see that for
00:15:23instance you can partial load, but for instance.
00:15:28If you have imaging that you are working between the case.
00:15:36Supply the water.
00:15:40Ok, so you have may be as in this case fifty percent of the factor.
00:15:47So in principal you could switch off on
00:15:50killer and work with love with Taiwan.
00:15:54Ok, but what happens is that you can
00:15:58see that you have to he potential problems.
00:16:02Okay he.
00:16:05Is that you can see that you are you have
00:16:10fifty of load factor so it means that of
00:16:16working between six point sex and the point
00:16:20okay you work with the use of the way that they
00:16:26which is which means that is that you have
00:16:31the return of the point to it is in the same conditions.
00:16:37Ok, but of course the the the pumps
00:16:43are running through verso distillerie switch off point di crisi.
00:16:49And for the FLAURA2 is passing through the one in this case.
00:16:58Will have point for which is between point to point to say so.
00:17:06In this is it could be okay you could.
00:17:13Be that if you need is to game years.
00:17:19If you have to he supply del water due unit che il bidet working
00:17:27this is the difference between
00:17:31war and to help you to ok could lead to not.
00:17:37Okay, so if the case you should.
00:17:45Lower distant in order to lower di lower average.
00:17:52Ok. Ehm.
00:17:55Bah. If you want to lower
00:17:58distant you have to lower this che and that the problem
00:18:03because you need to than lower evaporazione temperature
00:18:09which could lead to the problem ok can have ice Commission.
00:18:16Okay, so it is not always in the problem,
00:18:22okay on the independent on the size of
00:18:26the current coil and so on demand on the author conditions.
00:18:31Ok, but the principal problem in the fiction o dei.
00:18:40So dis may not be problem as as you have tu killers,
00:18:46but if you have three killers.
00:18:48Ok. Dan de de de lod operations
00:18:53es de che we have years che so.
00:19:01Up to the killers that solution could be ok ok,
00:19:05but since or DUO-E to the problem that you make up for.
00:19:11You usually not work with more than to
00:19:16killers KEE because it. Mi dia problemi.
00:19:22Ok, ok, so. This is.
00:19:31Ok. Lo so.
00:19:36Ok, no problem is that by.
00:19:40Let's let's go to have so much.
00:19:46Okay, so no.
00:19:48This is the other solution.
00:19:51Ok so. The solution is to work with constant FLAURA2
00:19:55in boss The primari e secondari for
00:20:01large for size plants constant in progress in
00:20:08the second world wide web variable FLAURA2 because this is
00:20:16the trend today is to try to work with the variable FLAURA2
00:20:24because this is you can Ok reduce
00:20:28the hem the energy related the Ok,
00:20:35so dissi se sketch of what you could do ok to keep the he to still
00:20:45live constant FLAURA2 in
00:20:48the he is this is the time.
00:20:57And so what you should do you usually you work
00:21:05with e bypass so bypass What is this is this is Ok,
00:21:14you have the year is constant Ok,
00:21:21but the flow rate ok in the in the day for
00:21:27the users is variable and as you can see that You have.
00:21:47You have? You have to find which is
00:21:54modules In quei due which is modulo di in the return or not.
00:22:01Ok, ok. Ok.
00:22:07Which is reduced the inside
00:22:11the emissions system so by using the floating emission system.
00:22:16You will reduce the love and you can work
00:22:20love and in the different emission,
00:22:24of course if you reduce the year.
00:22:27Ben al di sotto del io
00:22:34voto OK. And you need to save the world,
00:22:41you do it means that if you are you have e. Highlight in this is
00:22:50the key and the green error so must have on this.
00:23:02Time is less than the FLAURA2.
00:23:09You are that you are working with in the killers,
00:23:14then you need e bypass KEE bypass highlight in
00:23:19blue so you will have bypass have which is.
00:23:27Which is he bypass del FLAURA2.
00:23:31Ok and we go to work always with
00:23:36constant FLAURA2 on the he on the killers ok
00:23:42and you can vari the de FLAURA2 to
00:23:47the different users ok by by passing corrisponde ok,
00:23:54ok su the sound
00:23:58of the bypass FLAURA2 and the FLAURA2 that is going to the building
00:24:02ok is to the constant
00:24:05in the production of the production for the Cines.
00:24:10Ok, io penso con la mia famiglia.
00:24:21E gli esiti on the city,
00:24:24Onde sonore Yes, yes,
00:24:28we To look at the return.
00:24:32Yes, Yes. Okay. Ehm, so in
00:24:38this case This is this is the.
00:24:45He is the.
00:24:50Study to the one on the user side secondary FLAURA2 and.
00:25:01Ok. So that is the possibility year,
00:25:10you can see the end,
00:25:12of course in this case.
00:25:14Ok, we have ena de saint point that we segue i tuoi soldi.
00:25:21Ok, ok skip this because this is a little bit Complicate.
00:25:28Ehm yes, so what we have seen so far is that as you can see here.
00:25:38We consider the che so we had just the pumps on
00:25:45the end of the end of the primary circuit, of course.
00:25:54If we have the if you have
00:25:57he large distribution system on the second key.
00:26:02He then we have variable speed.
00:26:07Ok. Nel secondo caso de de de de de de.
00:26:17De de FLAURA2 between the between the second we have
00:26:24the two different solutions solutions
00:26:29to have the variable speed pumps on
00:26:34the secondary circuit bypass or
00:26:40to be that we have like many fold and
00:26:43then we have the can distributed the water.
00:26:46E se penso che with the pumps KEE in this case ok,
00:26:56we have that we have a case Ok whether we
00:27:03are just in time or if we have different KEE in this case.
00:27:10We have always the bypass KEE here in order to
00:27:16work at constant at constant florent in the city.
00:27:22Ok. Ehm, Ok, no?
00:27:28Let's have a look at this look at how you can control the killer.
00:27:36Ok. Ehm, okay, so.
00:27:42Be, the killer, okay.
00:27:46Are usually controlled on the return of
00:27:50the circuit you control
00:27:54the temperature on the return of the city and you know.
00:27:59Why Ok, so in this case.
00:28:04What we have to think about is the world is Ok, so we con.
00:28:12Temperature on the return and in
00:28:17this case we need to consider what we need to consider
00:28:22that we can activate why I can activate
00:28:28ok hem de partial load operation of killer.
00:28:34Ok, sono uguali.
00:28:37Can be in for steps,
00:28:40ok, so you can work.
00:28:43With the work he he.
00:28:50Is. Not ok,
00:28:57so imagine that you can work can you can.
00:29:03Can because maybe you know how to win for compresse.
00:29:13Or in Compressor?
00:29:19Word. Of. This is the world.
00:29:30Ma sei tu che non so imagine that you
00:29:34can you can he work every fifty.
00:29:46So it means that if you stop if you go from one step by.
00:29:59Step one.
00:30:02Ok. Ok,
00:30:06so if you go from the pending if you are in crisi
00:30:11in the power of the crisis the power then.
00:30:16What you do you?
00:30:22If you are using.
00:30:29The imaging that you imaging that the lodo
00:30:35the building is less
00:30:38than the design power that you have or the killers.
00:30:42Ok imaging that you want
00:30:47to go from one of course when the killer start start.
00:30:53Okay, so switch in system killer.
00:30:58Ok, the pending on how much load you have Ok then.
00:31:04In principio if you need less than
00:31:08ok when you can you can work on the road.
00:31:14Okay, you go from this is
00:31:17the key imaging that you have you need complesso,
00:31:23gli switch off sono un complesso processo sottile,
00:31:27ma dei segni complesso working to different.
00:31:32Non so in this case Ok,
00:31:36Let's let's also just one killer.
00:31:41Case Okay.
00:31:43You will then switch off reviews Ok which
00:31:50means that the end if you keep supply central constant.
00:31:58Tratto da The Return di
00:32:03The Walking Dead FLAURA2 than the wild in Cristo.
00:32:14Ma di Cristo.
00:32:17Che cosa infatti,
00:32:18penso che if you start wars that
00:32:22if you need power to keep the constant FLAURA2.
00:32:30And you will need some time.
00:32:35Okay. In order that the temperature sensor will
00:32:39ok right to the. This is the.
00:32:46End of course he.
00:32:52Is on the time,
00:32:58which means on the he sempre tournament and end to
00:33:07the steps because I need to consider
00:33:11then that you have water circulation, che so you have.
00:33:17Ehm. Ehm certo.
00:33:20Amount of water ok,
00:33:22so you have thermal energia,
00:33:24the system and by going from one
00:33:27to win it's time in order to have the response of the system.
00:33:35Ok. Ehm Berselli from the city and so so if you keep
00:33:45te cosa and you reduced step by step
00:33:49the love you will decrease the temperature difference, of course.
00:33:55If you go around you
00:33:59will be in crisi in
00:34:01the factor load you will increase the temperature difference.
00:34:06Okay now try to explain it is
00:34:11important to measure the return to keep the control and return.
00:34:17Okay, so clear. This is the concept of okay,
00:34:26so the blue lines presents the stack differenti.
00:34:31Okay, so che step differentie means that the death
00:34:35is going to save the fifty five or.
00:34:40Non serve essere competitivi in
00:34:42caso di crisi in download o in crisi.
00:34:45De he and this is the blue line Okay,
00:34:50the green arrow is instead presenti the history of the difference.
00:34:59Ok, ora so.
00:35:09Let's consider this conditions imagine work in this conditions.
00:35:16Okay, so La start with solutions between
00:35:20let's say he he working with
00:35:24tempi di crisi e supply and degree in
00:35:29case you for steps KEE usually
00:35:35what you consider is the control key on for
00:35:40the child de de de de de cooling system for five rich che
00:35:49but you work with for steps so you can see
00:35:54the one di crisi difference che di crisi difference per step.
00:36:01Ok, E se sì, quale crisi?
00:36:05Ok in order to for the switch off
00:36:09of the system perché so lets suppose
00:36:14that your system is operating at ok as return so this is the week.
00:36:24End this is the che so the supply in
00:36:30this is not so imagine that the load.
00:36:36Imaging that the load of the building
00:36:40of the building because this is this
00:36:45is the law of the building will
00:36:48is so if you don't need one of the power building,
00:36:55then what happens that
00:36:57the temperature supply return
00:37:00will decrease because you don't have to exchange.
00:37:04De de de load as it design conditions
00:37:09so both the supply and return will decrease.
00:37:15Ok, so now imaging what you are?
00:37:21Di Chris Supply braccio down to crisi and in this Ok supply.
00:37:33Side. Yes, of course.
00:37:40Sono immagini di imaging.
00:37:44Okay. Your measuring the return to
00:37:48the return temperature as well as the supply in the supply
00:37:54the return of your return on this is
00:38:00the return Ok. And this is
00:38:03the temperature of the return che
00:38:06so this is the return Temperature che.
00:38:10In this case You are you rich eleven degrees?
00:38:17Ok, so this is this moment,
00:38:21you will go from one under 25% of the road.
00:38:27So you switch one step will do it in this case,
00:38:35you will have he he you you will decrease
00:38:42download de de de de de cool power One step which will.
00:38:52Which will mean to reduce or to increase one degrees
00:38:59detentrice he of the supply design time
00:39:05you will have the supply will be ok supply height.
00:39:11Ok. e now if you do if you are
00:39:16if if you need more than five percento less del 25%,
00:39:23che so if the load will be higher ben 7% del boss.
00:39:29The return increase ok,
00:39:32if you don't need this power, then again,
00:39:36you will have a lover of the supply and
00:39:39return KEE he sono imaging that
00:39:43you don't need last of the power than the again.
00:39:52He will be it means that boss
00:39:55the return and supply will decrease ok and
00:40:00in this case ok. De de de de Typekit,
00:40:08quindi che in this case will be even bless
00:40:12we will reach so you will del.
00:40:21Diritto internazionale?
00:40:24Okay. Working with now.
00:40:31Ah, ok, ok. Because no with.
00:40:38So image that you will you need you have?
00:40:44Okay, so you switch off again,
00:40:47you go from fifty veloce.
00:40:51Okay, so you.
00:40:55Go here and more than fifty
00:41:01you you will have an increase
00:41:04if you don't need fifty percento of the road,
00:41:07Then you will decrease
00:41:10this is the return temperature will power decreased.
00:41:15Sì, ok.
00:41:17He and you will not from the twenty.
00:41:23Okay. Now again.
00:41:29It's the power is for you will
00:41:33increase you will have the one and it.
00:41:38IT. Parlar di crisis okay,
00:41:42you will e this moment you know that you have to switch off the.
00:41:53One switch off you have to the penny,
00:41:59Non you will have.
00:42:03Okay, and if the temperature In tempo di crisi.
00:42:12Ok, then you know that you will have
00:42:15to switch on again on compressor.
00:42:21Okay down.
00:42:26In caso che il viaggio nel complesso.
00:42:34Imaging that you will
00:42:37be the temperature of the water will increase so you will
00:42:42be sì on the return to you with
00:42:46the second step and so che suo padre,
00:42:52in crisis and of course the new year.
00:42:56Ok, ok.
00:42:59In this case you have want.
00:43:04You can see that you can
00:43:07Ok. Ok. You can
00:43:14work with the steps.
00:43:18Ok what happens?
00:43:23What if you have if you work on the supply,
00:43:29if you work on the supply.
00:43:31Temperature ok, then you need to
00:43:35work with a greater steps key because in case.
00:43:39Eh eh.
00:43:43Sì, che so,
00:43:46let's consider this case,
00:43:49Let's consider step always on so what you are here is in this case,
00:43:57you are working at the supply.
00:43:59Temperature Ok. Eh no. Of course.
00:44:05It's the supply is he eleven.
00:44:10Sì, ok, ok.
00:44:15If the supply the crisis,
00:44:20he then you have you will work with a step.
00:44:28Ok, so imaging that is the one step,
00:44:34Ok, then you will know.
00:44:38If you will one step,
00:44:42you don't know exactly ok you will make
00:44:44a switch off switch on off so you
00:44:48need e switch is
00:44:51greater than the steps because of work on the supply.
00:44:56Not on the return. Ok, so in this case
00:44:59imaging that you have one step in più.
00:45:04Eh Di crisi, anzi.
00:45:06Ok. He so you can be supply the world between.
00:45:13Them and see you will not be able okay you will not be
00:45:20able to control the temperature ok on the return yes,
00:45:26yes so the only way to to work or to control the.
00:45:37Control Decidersi on the time,
00:45:41but on the other side Ok, you need also.
00:45:47Ok il dorso.
00:45:50Di un dito so tu considera te,
00:45:54ma tu considera he proper work operation should be to work
00:46:03Quando scrissi in bozze di mestiere
00:46:07il steps per testare on the temperature sensor
00:46:13che il water for the steps it is also let
00:46:18the amount to the KEE to the water that you have in
00:46:23the search and the he what is important crucial is
00:46:29to work on the thermal of the water in the circuit.
00:46:36Ok. Di cose as we are going to see this will
00:46:40affect the switch on off side
00:46:44by the the the most critical condition
00:46:52is you see.
00:46:55This is the balance that you have ok
00:46:59and here we have the ma che so,
00:47:04le statue de when we look at the balance.
00:47:10We have the killer,
00:47:12which are produced in this is the istantanea so the power,
00:47:17which is provided by the killers is I
00:47:22minus de los Angeles, which is.
00:47:30Not consider the lost key for
00:47:34preliminary hypothesis that is to be what this is
00:47:40the variations in the temperature over the time dependent on
00:47:44the other all the secret and of course the city.
00:47:49Ok now if you working if you looking et say de consider Il KEE.
00:48:00De mas considera dis mas of the water, which which is.
00:48:10The best KEE de critical condition is
00:48:17when the love is half of the killer.
00:48:24He power Ok why because this is related
00:48:31also to the steps that you can consider a suitable start up switch.
00:48:39Switch off. Ok, dai,
00:48:42have in ehm in in in,
00:48:48ma ci sono alcuni machine should not have
00:48:51more than one he startup per
00:48:58startup Del maximum del chicken for the machine KEE di cosa
00:49:06dice de de de del complesso sul not last for long time de minimum
00:49:16is the maximum is six startups
00:49:20dell'Est de la tre serie Six Startups.
00:49:27Ok, so best of this and the most critical condition
00:49:31is when you have which is the capacity.
00:49:36Ok, so he he is this is the power that we need to provided.
00:49:42This is the Lord of the power of the killer,
00:49:45which is that this is the question that you should use for
00:49:50sizing the use of the system so the voice of the system.
00:49:56Ok, so if this is Ok Max e Max,
00:50:04ma i gay so no.
00:50:09This is the question that we have seen gay,
00:50:13we said that we need and we can consider the delta T
00:50:21ok that is ok. Is
00:50:24the man of the water ship and number of special, che so.
00:50:30Zero point five Paola with
00:50:34the maximum the delta the minimum is Okay.
00:50:45Is ok de he six ok he one size divided tu gay
00:50:56if then New Year e di And
00:51:00this is the question that you need for sizing the use of
00:51:05the system of the use of the system should be at
00:51:08least or rather than ok the power of the killer
00:51:13divided by the by the number of steps and
00:51:19that of the history of which is the delta T of this is the Ok,
00:51:27so this is how you have to say.
00:51:30What is that you need to know
00:51:33which is the death of the series of the killer.
00:51:38You need to consider the number of he of which is usually six
00:51:49and in this case by using the question you
00:51:53can the master of the what the master of
00:51:57the water of the old the seguito KEE should
00:52:00be at least this because if you don't have enough water.
00:52:04Ok, then on one side,
00:52:08you will not be able to measure
00:52:12the change the temperature return because de de de change is in
00:52:18the temperature will be
00:52:20quickly than the response of the temperature of the sensor
00:52:24the end of the other size you will have
00:52:28to the one of side and the complesso wind break che.
00:52:36In.
00:52:40The pipes the water campaign to know because you have to design and
00:52:47to size the che deve essere diverso.
00:52:54If this is not is less than di one to had e valium e thank.
00:53:04You if you want just to the times and the one of
00:53:09the water or if you want to have e
00:53:12thank ok with which is for this forum.
00:53:16Ok, so x x x x and what is important Ok.
00:53:25X important the storage tank should be place in
00:53:32the return Ok remember always ok de de.
00:53:40De water storage ok should be always located
00:53:46in also for small size box.
00:53:52This is true for size,
00:53:55but for all for you need to have an e thermal storage storage
00:54:06if you have for because you have
00:54:11e. You can work with you need to storage one for each circuit.
00:54:20Ok. Eh?
00:54:25Yes. How are the any if you
00:54:30were with the variable speed compresso
00:54:34if you world wide inverter driver compressor.
00:54:37How do you usually work on the primary side?
00:54:42Usually the concept similar concept
00:54:46similar su you he of course in this case,
00:54:52you will not have you will not have this say he step by step,
00:54:58but you can work almost continuous,
00:55:00but you will measure.
00:55:03Anyway, the return you reduce
00:55:06the compressor speed down to the minimum frequency you
00:55:12can and when you reach the minimum frequency now stop
00:55:19the compressor you wait again
00:55:22that that we will increase and you will start working.
00:55:30And you will reduce speed compresso.
00:55:36In case remember that is
00:55:39always you have always to measure the return
00:55:43is the temperature control in order to
00:55:48have stable operation and very much important.
00:55:53The voice of the bigger the better.
00:55:59Times it is better life
00:56:04so usually you have to try to find the place the space in
00:56:10order to have e soluble in order to
00:56:14the void the best of the complesso even for.
00:56:20In compenso.
00:56:25I think it's not for today,
00:56:28Okay, see you tomorrow.
00:56:33Seymour Se. Sì, ok.
