Definitions

  • the invention relates to a method for stowing a condensation-prone good in a hold of a ship, in the interior of which air of determinable moisture and temperature is enclosed, which comes into contact with walls on which condensation can take place and in which the walls reach a temperature level at least in some areas be heated, on which a condensation of moisture on the walls is prevented.
  • This method is intended to prevent heat flow from cooled parts of a cargo space by heating intermediate walls in the area of this heat flow.
  • heaters are attached to the partition walls. With the help of this heater, a heat flow is generated in the area of the walls arranged between the cooled cargo holds. This heat flow compensates for the heat flow from the walls adjacent to the cooled cargo holds and prevents condensation of moisture in the area of the wall transitions.
  • This object is achieved in that the walls are heated in the area of their entire extent facing the goods in the area of their limits facing away from the goods to a temperature level preventing the condensation of moisture, a heat flow from the warm 'engineers towards the interior of the cargo space is generated and both the temperatures of the ambient air washing around the cargo and the temperatures of the walls are controlled to prevent condensation of moisture in the entire area of the cargo area.
  • a ship is known with at least one hold, inside of which a condensation-prone good is stowed and air of determinable moisture and temperature is enclosed, which comes into contact with walls on which condensation can take place.
  • a ship has become known from British Patent Specification 18 848, which has a cargo space enclosed by an inner wall. There is an intermediate space between the inner wall surrounding the cargo space and an outer wall delimiting the ship, into which air conditioning air is introduced. Depending on the area of application of the ship, it can be ensured with the aid of the appropriately tempered air that a desired climate is generated in the hold. However, no consideration has been given to heating the cargo space walls to a temperature which is sufficient to allow a heat flow to pass through the cargo space walls and which is dimensioned sufficiently large to prevent condensation of the air in the cargo space . Rather, condensation phenomena appear on the cargo space walls, which are particularly pronounced in the area of the cargo and lead to a spoilage of the stowed goods there.
  • the object of the present invention is therefore to improve the ship of the type mentioned in the introduction in such a way that condensation-sensitive goods can be stowed in its hold without fear of damage to the goods by condensation water.
  • the walls laterally delimiting the cargo space; the floor delimiting the cargo space in the ship's vertical axis at the bottom and a cargo space cover lying opposite the floor are at least partially formed as heated double-walled heat exchangers that heat the cargo space and have at least one interior through which a heating medium flows and with at least one the temperature of both the air and the walls are connected to a control device which keeps the condensation of moisture at a level.
  • Such a ship is particularly suitable as a bulk carrier for the transport of bulk water-sensitive bulk goods.
  • goods sensitive to condensation had to be packed in special packaging units, which in turn were stowed in the hold of a general cargo ship.
  • coffee could not be transported in bulk, although transportation costs make up a significant portion of the cost of coffee.
  • coffee can also be stowed in bulk in the holds of a bulk carrier, without the risk of condensation forming in the area of the goods lying against the walls.
  • the condensation-prone goods can also be packed in large units, such as containers, in the holds.
  • the containers standing in the appropriately tempered cargo holds have a temperature on their outer sides as well as on their inner walls facing the stowed goods that is sufficient to prevent the formation of condensation.
  • the transportation of coffee in bulk saves considerable transportation costs.
  • a ship consists of a hull 1, which has at least one cargo space 2. This cargo space 2 is enclosed on all sides by walls 3.
  • the walls 3 consist of a floor 4, two side walls 5, 6 extending in the longitudinal direction of the ship, two transverse walls 7, 8 extending in the transverse direction of the ship and a cover 9 which closes the cargo space 2 on its side facing away from the floor 4 and is designed as a hatch cover.
  • the hull 1 is designed with two shells, so that outer walls 10, 11, 12 extend parallel to the side walls 5, 6 and the bottom 4, between which and the side walls 5, 6 and the bottom 4 cavities 13, 14, 15 are formed are.
  • the cover 9 is also double-shelled and has an outer wall 16 running parallel to it, which together with it encloses a cavity 17.
  • the transverse walls 7, 8 likewise have outer walls 18, 19 running parallel to them on their sides facing away from the loading space, which together enclose cavities 20, 21 with them.
  • All cavities 13, 14, 15, 17, 20, 21 each extend on the side 28 of a wall 3 facing away from the loading space 2 over its entire surface area.
  • the cavities 13, 14, 15, 17, 20, 21 are each connected to at least one adjacent cavity 13, 14, 15, 17, 20, 21 via connections 22.
  • the cavities 13, 14, 15, 17, 20, 21 are flowed through by a heating medium used as a heating medium, which preferably consists of warm water. Cooling water can be used as water, which has been heated by a ship's engine 32 and is distributed evenly over the cavities 13, 14, 15, 17, 20, 21 via feed lines 33 and from there is led back to the ship's engine via leads 34.
  • At least one circulation pump 23 is provided, with the aid of which the hot water located in the cavities 13, 14, 15, 17, 20, 21 is constantly in motion is held and is exchanged between the individual cavities 13, 14, 15, 17, 20, 21 in order to avoid temperature differences on the walls 3.
  • the circulation pump 23 and the hot water supply is from. controlled by a thermostat control 31, which has temperature sensors 29, 30 in the hold 2 and via which the supply and circulation of the warm water is controlled in such a way that the temperature of the air in the hold 2 is kept constant during the entire transport.
  • Loads that are susceptible to condensation are filled into loading space 2 in a loading port.
  • the ambient air in the loading port penetrates into the cargo hold 2. It is of relatively high temperature and humidity, especially in overseas ports.
  • the charge also has a relatively high temperature. It is filled into the loading space 2 as bulk material.
  • the loading space cover 9 designed as a hatch cover is closed. Then the ship can sail. On the northern route, the ship will reach sea areas where both the air and water temperatures are significantly lower than those in the loading port. In particular, the outer walls 10, 11, 12 of the ship cool down considerably. The air contained in the cargo space 2 comes into contact with the outer walls 10, 11, 12, cools down there greatly, so that it approaches the condensation point of the liquid dissolved in it. In order to prevent the condensation of moisture, the heat medium is moved through the cavities 13, 14, 15, 17, 20, 21 with the help of the circulation pumps 23. The heat medium has the temperature of the air enclosed in the cargo space 2, so that it cannot cool down on the walls 3. It is able to keep the moisture it contains dissolved without showing any signs of condensation at any point.
  • the termostats scan the temperature on the walls 3.
  • the measurement results are entered into the termostat control 31.
  • This controls the circulating pump 23, with the aid of which a quantity of cooling water corresponding to the respective temperature conditions is pumped, which leaves the ship's engine at the outlet 35 in the hot state and re-enters the ship's machine 32 via the derivatives 34 at an inlet 36.
  • a heat exchanger through which the cooling water flows can be arranged between the outlet 35 and the inlet 36 of the ship's engine 32, which heat exchanger is not shown in the example.
  • the heat medium is heated to the extent that it is able to keep both the walls 3 and the interior of the cargo space 2 at a temperature at which condensation of the moisture dissolved in the air is avoided.
  • the heat can be dissipated from the walls 3 directly into the interior of the hold 2.
  • 2 longitudinal bulkheads 37 and transverse bulkheads 38 extend in the interior of the loading space, which are connected to the cavities 13, 14, 15, 21 via connections 22. These longitudinal bulkheads 37 and transverse bulkheads 38 can also give off heat to the interior of the loading space 2.
  • a measuring sensor 39 in the interior of the cargo space 2, which is suitable for measuring the humidity of the air enclosed in the cargo space 2.
  • This sensor 39 is connected to a computer 41 via a measuring line 40.
  • control pulses from the termostat control 31 are fed into the computer 41 via a further line 42.
  • This computer 41 has a program that can be used to calculate the condensation point of moisture in the. air trapped in the hold 2 is released. According to the moisture value determined by the computer 41, the thermostat control 31 is controlled to a temperature level at which the condensation of the moisture in the cargo space 2 is just being avoided.
  • all outer walls 10, 11, 12, 16, 18, 19 are provided with insulation 24, each of which extends over the entire surfaces of the outer walls 10, 11, 12, 16, 18, 19 each extend on the sides facing the cavities 13, 14, 15, 17, 20, 21.
  • ribs 43 or other measures improving the heat transfer can be provided in the cavities 13, 14, 15, 17, 20, 21. Good heat transfer from the heat medium flowing through the cavities 13, 14, 15, 17, 20, 21 to the walls 3 takes place at these ribs 43.
  • the fan 25 which is expediently provided in the area of the hatch cover 9, ensures that the most ideal possible temperature compensation takes place. For this purpose, it keeps the air trapped in the hold 2 in motion and in this way avoids the formation of condensation.
  • the loading space cover 9 which is designed as a double-shell hatch cover, has, in the area of its connections 22 with an adjacent cavity 13, 20, 21 attachment points 26 at which the connections 22 are detachably attached, so that the hatch cover can be removed for loading and unloading.
  • closure members 27 are preferably provided, with which the attachment points 26 on the loading space cover 9 can be closed so that the water contained in the cavity 17 does not flow out. However, this water can be drained off before the loading space cover 9 is removed in order to reduce its weight.
  • a further hot water source can be provided. It is also possible to provide electrical heating instead of hot water heating, for example in the form of heating elements which extend uniformly over the walls 3 on their sides facing away from the loading space 2.
