Description
10 15 20 25 30 456 055 2 och genom att kyla lastbehâllarna var och en fås ett flexibelt system, som är lätt att hantera, liksom att lastutrymmet bättre kan utnyttjas. 10 15 20 25 30 456 055 2 and by cooling the cargo containers each a flexible system is obtained, which is easy to handle, as well as that the cargo space can be better utilized.
Vid kylning av laster, vars transporttemperatur ligger nära f0°C eller vid fryslaster kommer kylenheten att bli påfrostad och måste avfrostas. Detta sker vanligen genom elektriska element instuckna i luftkylaren, som kopplas på samtidigt som den normala köldmediecirkulationen till luftkylaren stoppas och cirkulationsfläkten stannas.When cooling loads whose transport temperature is close to f0 ° C or at freezer loads, the refrigeration unit will be defrosted and must be defrosted. This usually occurs through electrical elements inserted into the air cooler, which are connected at the same time as the normal refrigerant circulation to the air cooler is stopped and the circulation fan is stopped.
När de elektriska elementen varit tillslagna en stund har en del is på luft- kylarna smält men samtidigt börjar luften värmas upp. Den värmda luften stiger upp och strävar efter att komma så högt som möjligt. Härvid trycks den övre, kalla luften i systemet nedåt och åstadkommer en luftcirkulation genom lasten i motsatt riktning mot den vid kylningen, varmed följer att den kallare luften strömmar bakvägen in i luftkylarenhstens undre del för att därefter värmas upp av avfrostningselementen. Härmed har en icke önskad cirkulation uppstått som avsevärt försvårar avfrostningen och förlänger av- frostningstiden.When the electrical elements have been switched on for a while, some ice on the air the coolers melt but at the same time the air starts to heat up. The heated air rises and strives to get as high as possible. Press here the upper, cold air in the system downwards and causes an air circulation through the load in the opposite direction to that during cooling, with which it follows that the colder air flows backwards into the lower part of the air cooler unit to be subsequently heated by the defrosting elements. Herewith has an unwanted circulation has occurred which significantly complicates defrosting and prolongs the frosting time.
Olika typer av kända mekaniska stänganordningar kan tänkas men dessa ford- rar antingen en insats i arbete eller kostar effekt vid den normala driften.Different types of known mechanical closing devices are conceivable, but these either an effort at work or costs effect in normal operation.
REDOGÖRELSE FÖR UPPFINNINGEN' Föreliggande uppfinning avser att vid en kylanordning av ovannämnda slag på ett enkelt och ur effektbehovssynpunkt snålt sätt spärra den icke önsk- värda luftcirkulationen vid avfrostning. Detta uppnås enligt uppfinningen genom en kylanordning som uppvisar de i patentkrav 1 angivna kännetecknen.DESCRIPTION OF THE INVENTION The present invention relates to a cooling device of the above-mentioned type in a simple and economically efficient way, block the unwanted value the air circulation during defrosting. This is achieved according to the invention by a cooling device which has the features stated in claim 1.
FIGURBESKRIVNING Ett utföringsexempel på uppfinningen beskrivs nedan i anslutning till bi- fogade Éštning, där fig 1 visar en lastbehållare med kylenhet och fig 2 visar ett avstängningsorgan.DESCRIPTION OF FIGURES An embodiment of the invention is described below in connection with attached Establishment, where Fig. 1 shows a cargo container with cooling unit and Fig. 2 shows a shut-off means.
BESKRIVNING AV UTFÖRINGSEXEMPEL I fig 1 visas en värmeisolerad lastbehållare 1 (s k porthole-container), vars ena gavelsída har en nedre och en övre öppning 2 resp 3 för anslutning 10 15 20 25 3 g 456 035 till en yttre kylenhet N, som exempelvis kan vara av det slag som visas i broschyr 752-L-1E "STÄLICON Container Cooling System" från STAL Refrigera- tion AB. Kylenheten U är försedd med en luftkylare 5 med avfrostningselement 6, en fläkt 7, nedre och övre förbindelsekanaler 8 resp 9 försedda med kopp- lingar 10 resp 11 för anslutning till lastbehållaren. Dessa kopplingar kan exempelvis vara av det i svenska patentskriften 7902196-O beskrivna utför- andet.DESCRIPTION OF EMBODIMENTS Fig. 1 shows a heat-insulated load container 1 (so-called porthole container), one end face of which has a lower and an upper opening 2 and 3, respectively, for connection 10 15 20 25 3 g 456 035 to an external cooling unit N, which may, for example, be of the type shown in brochure 752-L-1E "STÄLICON Container Cooling System" from STAL Refrigera- tion AB. The cooling unit U is provided with an air cooler 5 with defrosting elements 6, a fan 7, lower and upper connecting channels 8 and 9, respectively, provided with lings 10 and 11, respectively, for connection to the cargo container. These connections can for example, be of the embodiment described in Swedish patent specification 7902196-O other.
I den nedre förbindelsekanalen 8 är anordnat ett spärrorgan 12 i form av en stympad kon exempelvis tillverkad av mjuk plastfolie. Plastkonen 12, som visas i större skala i fig 2, är runt sin vida ände infäst i förbindelsekanalen 8 och runt sin smala ände är den försedd med ett flexibelt band i form av en ihålig hylsa 13 fylld med blyhagel. Plastkonen kan exempelvis ha en diameter på 0,5 m vid sin vida ände, en diameter på 0,3 m vid sin smala ände och en längd på 0,5 m. I fig 1 visas med pilar den normala luftcirkulationsrikt- ningen vid kylning. Lastbehållarens innehåll kyles genom att kyld luft blåses in genom den nedre öppningen 2, där luften sedan genom ett trall- verk 1H fördelas ut för att passera vertikalt genom lasten och sedan sugas tillbaka genom den övre öppningen 3 för att åter kylas vid passage genom luftkylaren 5. Luftströmmen håller därvid plastkonen fullt öppen. När där- emot luftcirkulationen stoppas, t ex vid avfrostning, sjunker den smala delen på konen ner och viker ihop folien och därmed spärras luftcirkula- tionen från motsatt håll.In the lower connecting channel 8 a locking member 12 in the form of a truncated cone, for example, made of soft plastic foil. The plastic cone 12, as shown on a larger scale in Fig. 2, is attached around its wide end to the connecting channel 8 and around its narrow end it is provided with a flexible band in the form of a hollow sleeve 13 filled with lead shot. The plastic cone can, for example, have a diameter of 0.5 m at its wide end, a diameter of 0.3 m at its narrow end and a length of 0.5 m. In Fig. 1, arrows show the normal air circulation direction. cooling. The contents of the cargo container are cooled by cooled air is blown in through the lower opening 2, where the air then through a trolley plant 1H is distributed to pass vertically through the load and then sucked back through the upper opening 3 to cool again when passing through the air cooler 5. The air flow keeps the plastic cone fully open. When against the air circulation is stopped, for example during defrosting, it narrows narrow the part of the cone down and folds the foil and thus blocks the air circulation. from the opposite direction.
Då ett spärrorgan av det beskrivna utförandet är applicerat i en kylenhet av ovannämnda slag undviker man vid normal luftcirkulation en viss kontrak- tion som annars finns, varför den effekt som åtgår att hålla konen utspänd helt kan försummas.When a blocking means of the described embodiment is applied in a cooling unit of the above type, a certain contracture is avoided during normal air circulation. tion that otherwise exists, why the effect needed to keep the cone taut can be completely neglected.
