Opfindelsen angår et containerskib med et centralt køleanlæg til flere containere, en fælles fremløbsledning og en fælles tilbageløbsledning til en kølevæske, samt stikledninger, som for hver container grener sig ud 5 fra disse ledninger og er forsynet med ventiler.The invention relates to a container ship with a central refrigeration system for several containers, a common flow line and a common return line for a coolant, as well as plug lines which for each container branch out from these lines and are provided with valves.

Et containerskib af denne art kendes fra US patentskrift nr. 3 440 834, hvor luft nedkøles centralt og føres til en gruppe containere via anlæggets kanalsystem, således 10 at indholdet i containerne køles ned. Dette har imidlertid flere ulemper.- 1) en forurening kan brede sig fra container til container. Således vil skimmelsvamp eller bakterier, som fin-15 des i én container, blive overført til andre containere. Indeholder en container frugt, som er overmoden, vil frugten i de containere, som er tilsluttet samme kanalsystem, tilsvarende blive for hurtigt modne.A container ship of this kind is known from US Patent No. 3,440,834, where air is cooled centrally and fed to a group of containers via the system's duct system, so that the contents of the containers are cooled. However, this has several drawbacks.- 1) a contaminant can spread from container to container. Thus, mold or bacteria found in one container will be transferred to other containers. If a container contains fruit that is over-ripe, the fruit in the containers that are connected to the same duct system will similarly ripen too quickly.

20 2) alle containere i samme gruppe har samme temperatur, og det er ikke muligt at regulere temperaturerne individuelt. Transport af containere, som skal opbevares ved forskellige temperaturer, medfører betydelige vanskeligheder mht. stuvning og trimning.20 2) all containers in the same group have the same temperature and it is not possible to regulate the temperatures individually. The transport of containers to be stored at different temperatures causes considerable difficulties in stowage and trimming.

Endvidere kan de forskellige containeres temperatur reguleres uafhængigt af hinanden, og hver container kan yderligere ventileres separat.Furthermore, the temperature of the different containers can be controlled independently of each other and each container can be further ventilated separately.

15 Det bemærkes, at der fra den hollandske patentansøgning 7116679 kendes et køleskib med flere rum, der hver indeholder sit eget separate regulerbare køleelement. Dette er imidlertid ikke et containerskib, og hertil kommer, at rummene ikke kan ventileres.It should be noted that from Dutch patent application 7116679 a refrigerator with several compartments is known, each containing its own separate adjustable cooling element. However, this is not a container ship and, in addition, the rooms cannot be ventilated.

enkelt container i et containerskib ifølge opfindelsen. Køleelementet består af en isoleret kasse 2, som har en indblæsningsåbning 3 og en udblæsningsåbning 4, som passer til modsvarende henholdsvis udblæsnings- og indblæs-5 ningsåbninger i en container (ikke vist).single container in a container ship according to the invention. The cooling element consists of an insulated box 2 which has an inlet opening 3 and an outlet opening 4 which corresponds to corresponding outlet and outlet openings respectively in a container (not shown).

I mellemrummet mellem køleelementet 1 og containeren kan der til forbindelse af disse være anbragt to oppustelige containerkoblinger 5 af den art, der eksempelvis er be-10 skrevet i den hollandske patentansøgning 6914425.In the space between the cooling element 1 and the container, two inflatable container couplings 5 of the kind described, for example, in Dutch patent application 6914425 may be arranged for their connection.

I den isolerede kasse 2 er der monteret en varmeveksler 7, hvorigennem der løber et kølemiddel (f. eks. brine), samt en ventilator 8, der tjener til at blæse den luft, 15 der skal nedkøles, ind over varmeveksleren 7 i køleelementet 1 og føre den nedkølede luft videre ind gennem containeren.Insulated box 2 has a heat exchanger 7 through which a refrigerant (e.g. brine) and a fan 8 which serves to blow the air 15 to be cooled into the heat exchanger 7 in the cooling element 1 are mounted. and pass the cooled air through the container.

Den således tilvejebragte luftstrøm er i fig. 2 angivet 20 med pile. I den isolerede kasse 2 er der yderligere monteret et spjæld 9, som lukker for passagen fra ventilatoren 8 til varmeveksleren 7, når ventilatoren 8 standser, og åbner igen, når ventilatoren atter sættes igang.The air flow thus provided is shown in FIG. 2 indicated by 20 with arrows. In the insulated box 2, a damper 9 is further mounted which closes the passage from the fan 8 to the heat exchanger 7 when the fan 8 stops and opens again when the fan is switched on again.

25 I den nedkølede luftstrøm i køleelementet 1 er der anbragt en temperaturføler 10, som er forbundet med en indretning (ikke vist), som kan indstilles til den temperatur, som ønskes i containeren. Denne indretning kan f. eks. bestå af en temperaturregulator til hver enkelt 30 køleelement. Den faktiske af temperaturføleren 10 målte temperatur sammenlignes med den ønskede indstillingstemperatur, og såfremt disse to temperaturer afviger fra hinanden, indreguleres en reguleringsventil, som er anbragt i enten tilbageløbsledningen 11 eller fremløbsled-35In the cooled air stream in the cooling element 1 is arranged a temperature sensor 10 which is connected to a device (not shown) which can be adjusted to the temperature desired in the container. This device may, for example, consist of a temperature controller for each individual cooling element. The actual temperature measured by the temperature sensor 10 is compared to the desired set temperature, and if these two temperatures differ from one another, a control valve located in either the return line 11 or the flow line 35 is regulated.

De til flere køleelementer hørende temperaturfølere 10 kan imidlertid også være tilsluttet en eller flere centrale temperaturregulatorer, som passende kan være en datamat, og dette er især hensigtsmæssigt, når der fin-10 des et stort antal køleelementer.However, the temperature sensors 10 of several cooling elements may also be connected to one or more central temperature controllers, which may suitably be a computer, and this is especially useful when a large number of cooling elements are found.

I en sådan central temperaturregulator (temperaturregulatorer) sammenlignes den faktiske temperatur i hvert køleelement tilsvarende med den for dette køleelement 15 indstillede ønskede værdi.In such a central temperature controller (temperature controllers), the actual temperature of each cooling element is compared accordingly with the desired value set for this cooling element 15.

Tilbageløbsledningen 11 og fremføringsledningen 12 til at lede kølevæsken fra og til køleelementet 1 kan være forbundet med henholdsvis én fælles tilbageløbsledning 20 14 og én fælles fremføringsledning 15 i et centralt kø leanlægs ledningsnet (fig. 2 og 3).The return line 11 and the feed line 12 for conducting the coolant from and to the cooling element 1 can be connected to one common return line 20 14 and one common feed line 15 respectively in a central cooling system wiring (Figs. 2 and 3).

Med henblik på at kunne ventilere containerens indhold er der i køleelementet 1 monteret en tilgangskanal 16 25 til frisk luft, samt en afgangskanal 17. Den ene eller begge disse kanaler 16, 17 er forsynet med et reguleringsspjæld (ikke vist), og kanalerne 16, 17 er forbundet med henholdsvis en fælles tilgangskanal 18 til frisk luft og en fælles afgangskanal (ikke vist).In order to be able to ventilate the contents of the container, an inlet duct 16 25 for fresh air and an outlet duct 17. A or both of these ducts 16, 17 are provided with a regulating damper (not shown) and ducts 16, 17 is connected to a common fresh air duct 18 and a common duct respectively (not shown).

30 Køleelementet 1 er ved hjælp af en kanal 19 forbundet med et apparat (ikke vist) til bestemmelse af kuldioxidindholdet. Dette apparat er forbundet med den allerede ovenfor nævnte indretning eller med en anden indretning, 35The cooling element 1 is connected by means of a channel 19 to an apparatus (not shown) for determining the carbon dioxide content. This apparatus is connected to the device already mentioned above or to another device 35
