Definitions

  • the present invention relates to a cooling system for con­tainer transportation according to the precharacterising part of Claim 1.
  • cooling system in the ship is connected to channel systems, arranged in each hold, for supplying cooling air to the containers.
  • the channel systems in the holds are provided with connection openings, possibly with some type of movable connection part to fit different containers, each container being provided with corresponding connection openings for cooling air.
  • the cooling system with its channels is insulated whereas the hold in the ship is not insulated.
  • connection part is there formed as a funnel-­shaped and collapsible blocking member which, in dependence on the direction of flow, is expanded and open or folded and closed.
  • SE-A-8700092-3 (EP-A-88 10 0209.1) gives an example of a connection part which can be turned by 180 degrees about a horizontal axis to adjust openings for cooling air in a centrally located channel system to openings for cool­ing air in containers of varying sizes.
  • the invention aims at developing a cooling system for con­tainer transportation of the above-mentioned kind, which allows effective cooling of the container contents in a rel­atively simple manner requiring less space than prior art cooling systems.
  • the invention suggests a cooling system for container transportation according to the introductory part of Claim 1, which is characterized by the features of the characterizing part of Claim 1.
  • the holds of the ship are insulated and cooled. Possibly, the holds can be divided into smaller insulated and cooled subspaces in order to obtain different temperature levels in the hold de­pending on the cargo.
  • a central refrigerating plant supplies the air coolers arranged in the holds with refrigerant. Fans cause the air cooled by the air cooler to circulate through the hold which is filled with containers, each individual container being provided with connection holes for cooling air. During its circulation through the hold, the cooled air will flow around and through each container.
  • stationary circulating fans as well as temperature sensors may be pro­vided, arranged in the ship and positioned in front of the two connection holes of each container.
  • a fan can also be used to remove ripening heat and carbon dioxide (if any). The air coming out of the container then blows out right in front of the temperature sensor associated to that fan which is not used at that time.
  • the temperature sensors connected to a central computer, which registers the ingoing and outgoing air temperature for each container, the time can be determined necessary for each fan to be in oper­ation to obtain the desired temperature level in the con­tainer.
  • the air temperature in the hold is adapted so that all containers in the hold will have its right temperature, in which case due account must also be taken of the vertical extension of the container stack.
  • one fan may constitute a standby fan for the other fan, or the fans may be used alternately to bring about an air circulation in the opposite direction in the container.
  • the cooling system for container transportation requires little space and is not very expen­sive, which makes it possible to make the ship shorter. This entails additional savings, per se. With an insulated re­frigerated hold, also refrigerated cargoes on platforms can be transported with the ship. With this type of cooling system for container transports, the drying up of the cargo and hence the weight reduction will be reduced.
  • a guide system Between the stacks of containers in the hold there is a guide system. By increasing the distance between the stacks of containers, a space wide enough for walking may be ob­ tained athwartships. For each level of containers there is then arranged a grating connected to the guide system. Con­nections for electricity supply and a connection for a pos­sible measuring transducer are provided for each container position close to the guide system. In this way it will be possible to also transport containers with integrated re­frigeration equipment in the hold of the ship. The air cool­ers with the fans in the hold then transport away transmis­sion losses and condenser heat from the air-cooled con­densers of the refrigerated containers.
  • Figure 1 shows the construction of an insulated hold 1 seen from the side of the ship, with a cooling system for con­tainers 2 according to the invention.
  • the holds are usually built up of cells, each cell accommodating two rows of stacked containers. In each cell the containers 2 are posi­tioned in parallel with the longitudinal direction of the ship.
  • a centrally located cooling plant (not shown) supplies one or more air coolers 3 adjacent to each cell with a re­frigerant.
  • channels 9 In the transverse bulkhead of the hold there are arranged channels 9 via which the cooling air from the air cooler 3 is transported into the hold.
  • the cooled air enters the hold near the bottom of the hold as indicated by arrow a.
  • the openings 4 of the containers are open and communicate with the surrounding space in the hold.
  • a fan 5 and a temperature sensor 6 may be arranged, displaceably connected to a transverse bulkhead, as symbolically indicated by the two lines 10.
  • the fans 5 are adapted to adjustably control the flow of cooling air from the hold space in front of the containers into the respective container 2.
  • the temperature sensors 6 are adapted to supply a centrally arranged calculating unit or computer with measured values, which are processed in the unit/computer.
  • the calculating unit or computer is then adapted to individually control the operation of the fans taking into account the individually measured temperature for maintaining a certain pre-deter­mined temperature level in each individual container.
  • a con­nection part 7 between the fan 5 and the connection opening 4 of the container 2 may be flexibly arranged to fit differ­ent types of containers. These connection parts 7 are preferably fixed to the fan structure or the bulkhead and do not prevent access of the surrounding cooling air to the fan.
  • the com­puter can easily calculate for how long time each fan 5 has to be in operation to individually control the cooling air supplied to the respective container 2.
  • the temperature of the air in the hold must also be adjusted such that all con­tainers 2 in the hold 1 are given their required temperature level. Since in a hold 1 with, for example, seven containers 2 stacked on top of each other, the air temperature is nor­ mally higher in the upper part of the hold than in the lower part. This means that a so-called duty cycle (portion of time cooling air in blown into the container by the fan) for the bottom container is perhaps only 10% whereas for the top container it is 90%.
  • One of the two fans 5 in front of the container 2 may be used as standby fan or to effect an oppo­site air circulation in the container 2 and hence a more uniform temperature inside the container.
  • a guide system Between the different stacked rows of containers 2 in the hold 1, there is usually arranged a guide system.
  • the space for the guide system can be increased so that a space, wide enough for walking, can be arranged at least athwartships, as shown in Figure 2.
  • This makes it possible to also transport containers with an inte­grated refrigerating plant in the hold.
  • the containers When loading these containers into a ship's hold, the containers are turned such that their integrated refrigerating plants are facing each other. This makes it simple to connect the different plants to the connections in the guide system.
  • the air cool­ers 3 arranged in the holds will then be used for transport­ing away transmission losses and condenser heat from all air cooled condensers of the integrated refrigerating plants.
  • the above-mentioned calculating unit/computer besides being adapted to individually control the fans with respect to temperature, may also be adapted to individually control the operating data of each refrigerated container which is pro­ vided with a refrigerating plant of its own, in order to ob­tain the best operating conditions - seen as a whole - for the entire transport of refrigerated containers.
  • the carbon dioxide concentration can be controlled centrally in order to attain a maximum storage time and the best quality of the products which are to be transported.
