Ingeniørfirmaefc Giersing & Stellinger._ (50 Overvågningsindretning til kølebeholdere, navnlig kølecontainere.Engineering firm of Giersing & Stellinger._ (50 Monitoring device for refrigerated containers, in particular refrigerated containers.
Opfindelsen angår en overvlgningsindretning for kølecontainere med køleagregat, navnlig en kølecontainer til transport pi skibe, ved hvilken der ved køleagregatets arbejde, den automatiske afrimning og overholdelsen af en forud fastsat køletemperatur afgives hvert sit signal, hvis tilstedeværelse overvåges, idet signalerne er tilført til hver sin signalindgang i en udnyttelsesindretning, som ved udeblivelse af alle signaler bringer en efterfølgende indikator- og/eller alarmindretning til at reagere.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a cooling device for cooling containers with a cooling unit, in particular a refrigerating container for transport on ships, in which, during the operation of the cooling unit, the automatic defrosting and the observance of a predetermined cooling temperature are output, each signal being monitored, the signals being supplied to each of its signals. signal input into a utilization device which, upon the failure of all signals, causes a subsequent indicator and / or alarm device to respond.
Ved kølecontainere er det kendt at anvende overvågningsindretninger af den ovennævnte art, ved hvilke et køleagregats arbejde, den automatiske afrimning og opretholdelsen af en forud fastsat køletemperatur indikeres ved, at kontrollamper pi et skibs kommandobro lyser. Disse lamper ml stadig overvåges, hvilket ved et stort antal containere kræver høj opmærksomhed. I mange drifts- 142380 2 tilfælde er det meget vanskeligt at erkende et alarmtilfælde og bedømme det rigtigt, da fx. den efter afrimning stedfindende tænding af den til indikering af køleagregatets arbejde tjenende kontrollampe i lamgere tid udgør et alarmtilfælde, medens en tænding i kortere tid ikke har nogen betydning.In refrigeration containers, it is known to use monitoring devices of the aforementioned kind, in which the operation of a refrigeration unit, the automatic defrosting and the maintenance of a predetermined cooling temperature are indicated by the lights on a ship's bridge of command. These ml lamps are still monitored, which requires high attention for a large number of containers. In many operating cases, it is very difficult to recognize an alarm case and judge it correctly, as e.g. the ignition which occurs after defrosting the indicator lamp which serves to indicate the work of the cooling unit for a longer period of time constitutes an alarm case, while a shorter ignition is of no significance.
Opfindelsen har til opgave at tilvejebringe en indretning, med hvilken et alarmtilfælde kan angives tydeligere end hidtil netop ved kølebeholdere.The object of the invention is to provide a device with which an alarm case can be indicated more clearly than hitherto precisely with cooling containers.
Løsningen af denne opgave består ved en overvågningsindretning af den indledningsvis nævnte art ifølge opfindelsen i, at udnyttelsesindretningen har et tidsorgan, ved hvilket det som kriterium for køleagregatets arbejde tjenende signal begrænses til en indstillelig varighed.The solution of this task consists of a monitoring device of the kind mentioned initially according to the invention in that the utilization device has a timing means by which the signal serving as a criterion for the cooling unit's work is limited to an adjustable duration.
På denne måde opnås en bedre overskuelighed, da der kun behøves en enkelt lampe for hver kølebeholder, som skal overvåges. Udnyttelsesindretningen kan anbringes udenfor, så at man til en alarmmelding over en større afstand, fx. fra et skibs lastrum til kommandobroen, kan nøjes med et væsentligt mindre antal ledninger.In this way, a better clarity is obtained, since only one lamp is needed for each cooling container to be monitored. The utilization device can be placed outside so that an alarm message is displayed over a greater distance, e.g. from a ship's cargo room to the command bridge can be satisfied with a significantly smaller number of wires.
Hensigtmæssigt er den indikator- og/eller alarmindretningen fødende strømvej udformet som hvilestrømvej. På denne måde reagerer overvågningssystemet også ved svigten af spændingsforsyningen (åbne stikforbindelser, ledningsbrud), så at sikkerheden forøges.Conveniently, the indicator and / or alarm device feeding current path is designed as a rest current path. In this way, the monitoring system also responds to the failure of the power supply (open plugs, wiring) to increase safety.
To udførelseseksempler for opfindelsen er skematisk vist på tegningen.Two embodiments of the invention are shown schematically in the drawing.
Fig. 1 viser en overvågningsindretning for en kølebeholder og fig. 2 en overvågning af flere kølecontainere i et skib.FIG. 1 shows a monitoring device for a cooling container and FIG. 2 shows the monitoring of several refrigeration containers in a ship.
......I fig. 1 betegner 1 en kølebeholder, hvis indre rum køles af et køle- agregat. Til en stikdåse 2 fører ledninger, gennem hvilke signalerne til overvågning af køleprocessen afgives. En stikkontakt A er forbundet med den fælles ledningspol for alle signalstrømveje, medens der ved hver af stikkontakterne B, C og D står et signal, når køleprocessen forkøber rigtigt....... In FIG. 1 denotes 1 a cooling container whose interior space is cooled by a cooling unit. To a socket 2 leads wires through which the signals for monitoring the cooling process are output. A socket A is connected to the common wiring harness for all signal paths, while at each of the sockets B, C and D there is a signal when the cooling process proceeds properly.
Ved normal driftsforløb køler kompressoren kølebeholderen ned til en forud fastsat temperatur. Ved stikkontakten B ligger der et potential, så længe kompressoren løber eller er udkoblet. Med visse mellemrum afrimes køle-agregatet automatisk. I så fald ligger der en spænding ved stikkontakten C. Afrimningsprocessen fører almindeligvis til, at temperaturværdien overskrides og atter må bringes på den forud fastsatte værdi ved fornyet drift af kompressoren.In normal operation, the compressor cools the cooling tank to a predetermined temperature. At socket B there is a potential as long as the compressor is running or switched off. At certain intervals, the cooling unit is automatically defrosted. In this case, there is a voltage at the socket C. The defrosting process usually results in the temperature value being exceeded and again having to be brought to the predetermined value upon re-operation of the compressor.
Ved hjælp af en firpolet ledning kan der over et stik 3 tilsluttes en udnyttelsesindretning 4 til stikkontakterne A-D på kølebehilderen. De til signalindgangene a,b,c,d tilførte signaler udnyttes således, at en efter udnyttelsesindretningen 4 indkoblet indikator- og alarmindretning 5 bringes til at reagere ved udeblivelse af alle signaler. De ved signalindgangene b-d stående 142380 3 spændinger ensrettes ved hjælp af broensrettere 6, 7 og 8, glattes med kondensatorer 9, 10, 11 og tilføres til et relæ 12 hhv. 13. Relæet 12 er forsynet med en afbryderkontakt 12a, som ligger i strømvejen til indikator- og alarmindretningen 5. I strømvejen med den i hvilestilling åbne kontakt 12a er der endvidere anbragt et relæ 20, hvis i hvilesti-llingen sluttede kontakt 20a er koblet i serie med en signallampe 21 og/eller en summer 22. Signallampen 21 og summeren 22 fødes fra en jævnspændingskilde.By means of a four-pole cable, a utilization device 4 can be connected to the sockets A-D on the refrigerator via a plug 3. The signals applied to the signal inputs a, b, c, d are utilized such that an indicator and alarm device 5, which is switched on after the utilization device 4, is caused to respond by the absence of all signals. The voltages at the signal inputs b-d are rectified by means of bridge rectifiers 6, 7 and 8, smoothed with capacitors 9, 10, 11 and applied to a relay 12 respectively. 13. The relay 12 is provided with a switch contact 12a, which is located in the current path of the indicator and alarm device 5. In the current path with the switch 12a open in the rest position, a relay 20 is provided if the contact 20a terminated in the rest position is switched on. series with a signal lamp 21 and / or a buzzer 22. The signal lamp 21 and buzzer 22 are supplied from a DC source.
Hvis den indre temperatur i kølebeholderen 1 ligger inden for det fastsatte område, er der spænding ved signalindgangene a,d, og relæet 12 er trukket, si at den tilhørende afbryderkontakt 12a i den som hvilestrømvej udformede udgangsvej fra overvågningsindretningen 4 er sluttet, medens relæet 20 er trukket og dens afbryderkontakt 20a åben.If the internal temperature of the cooling vessel 1 is within the set range, there is voltage at the signal inputs a, d and the relay 12 is drawn, so that the associated switching contact 12a in the output path of the monitoring device 4 is closed, while the relay 20 is drawn and its switch contact 20a open.
Ved automatisk afrimningsdrift ligger der spænding ved signalindgangene a og c, og relæet 13 er trukket. Afrimningen medfører, at temperaturen forøges over det fastsattte område, og at spændingen mellem signalindgangene a og d falder til nul. Til forhindring af, at en afrimningsproces udløser alarm, er der anbragt en forbindelse mellem strømvejen med relæet 12 til strømvejen til relæet 13 over en diode 14, således at relæet 12 forbliver trukket.In automatic defrost operation, there is voltage at the signal inputs a and c and the relay 13 is drawn. The defrost causes the temperature to rise above the set range and the voltage between the signal inputs a and d to zero. To prevent an defrosting process from triggering an alarm, a connection is provided between the current path of the relay 12 to the current path of the relay 13 over a diode 14 so that the relay 12 remains drawn.
Det under afrimningsprocessen trukne relæ 13 forbereder med sin afbryderkontakt 13a et tidsorgan 15. Når afrimningsprocessen er afsluttet, indkobler kontakten 13a tidsorganet 15 og dermed det yderligere relæ 16. Løbetiden for dette relæ 16 kan indstilles ved hjælp af en fast modstand 17 og et potentiometer 18. Indstillingen er hensigtmæssigt regulerbar inden for et område på 10-60 minutter.The relay 13 drawn during the defrosting process prepares with its switch contact 13a a timing means 15. When the defrosting process is completed, the switch 13a engages the timing means 15 and thus the additional relay 16. The running time of this relay 16 can be set by means of a fixed resistor 17 and a potentiometer 18 The setting is suitably adjustable within a range of 10-60 minutes.
Efter en afsluttet afrimningsproces indkobles kompressoren automatisk for atter at bringe temperaturen inden for det fastsatte omrade. Da der i så fald opstår spænding ved signalindgangenge a,b, trækkes relæet 12 over den sluttede kontakt 16a og en diode 19. Hvis kompressoren efter udløbet af den på tidsorganet 15 indstillede tid endnu ikke har nået den fastsatte temperaturværdi, falder relæet 16, hvilket bevirker, at kontakten 16a åbnes og relæet 12 bliver spændingsløst. Derved åbnes kontakten 12a, og der udløses alarm.After a defrosting process is completed, the compressor is automatically switched on again to bring the temperature within the set range. In that case, when voltage is generated at signal inputs a, b, relay 12 is pulled over the closed contact 16a and a diode 19. If, after the expiry of the time set on the timer 15, the relay 16 has not yet reached the set temperature value, the relay 16 drops. causes the contact 16a to open and the relay 12 to become energized. The contact 12a is thereby opened and an alarm is triggered.
Ved hjælp af det indstillelige elektroniske tidsorgan 15 spærres altsa alarmen også efter afrimningen, indtil kompressoren normalt har bragt temperaturen til den forud fastsatte værdi.Thus, by means of the adjustable electronic timing means 15, the alarm is also blocked after defrosting until the compressor has normally brought the temperature to the predetermined value.
Som følge af at hvilestrømvejen, som føder indikator- og alarmindretningen 5, er galvanisk adskilt fra signalstrømvejen, formindskes risikoen for driftsforstyrrelser væsentligt, navnlig ved anvendelse på skibe.Due to the fact that the resting current path which feeds the indicator and alarm device 5 is galvanically separated from the signal current path, the risk of operational interruptions is significantly reduced, especially when used on ships.
Til optisk indikering af et alarmtilfælde kan hensigtmæssigt også anvendes en lystrykafbryder. En sådan lystrykafbryder kan tillige anvendes til 142380 4 undertrykkelse af en alarm, hvis der ved et flertal kølebeholdere for øjeblikket ikke er tilsluttet nogen kølebeholder til en overvågningsindretning. Parallelt med lystrykafbryderen kan summeren 22 være forsynet med en kvitteringstast. Hvis overvågningsindretningen anvendes ved kølebeholdere 1, der er udformet som kølecontainere til transport på skibe, er det hensigtsmæssigt at anbringe den optiske og/eller akustiske alarmindretning 5 på broen og at sammenslutte udnytteisesindretningerne 4 for de enkelte containere i grupper i en driftsgang mellem containere (fig. 2). Hvis der samtidig i hvilestrømvejen ved udgangen fra overvågningsindretningen 4 forbindes en ledningspol til stel M, behøver man kun at føre én ledningspol pr. container til broen eller til et andet overvigningssted.For optical indication of an alarm case, a light pressure switch can also conveniently be used. Such a light pressure switch can also be used for suppressing an alarm if, for a majority of cooling containers, no cooling tank is currently connected to a monitoring device. Parallel to the light pressure switch, the buzzer 22 may be provided with an acknowledgment key. If the monitoring device is used for refrigeration containers 1 designed as refrigeration containers for transport on ships, it is appropriate to place the optical and / or acoustic alarm device 5 on the bridge and to combine the utilization devices 4 for the individual containers into groups in an operation between containers (Fig. 2). If, at the same time, in the resting current path at the output of the monitoring device 4, a conduit coil is connected to frame M, then only one conduit coil per conductor is required. container to the bridge or to another monitoring site.
I stedet for en enkeltmelding for hver container kan der også angives en samlet melding pr. containergruppe, -stabel eller for hver luge til broen.Instead of a single message for each container, a total message per message can also be specified. container group, stack, or for each hatch to the bridge.
Det er også muligt at føre en parallel strømvej ind til maskinalarrnanlægget.It is also possible to lead a parallel flow path into the machine arrangement.
