Abstract

(57) [Summary] [Purpose] Within the cargo refrigeration compartment 3 of the cargo refrigeration barge 10 that is integrated with the cargo bay mouth part 1, the cargo refrigeration barge inside the cargo bay mouth part 1 and below the upper deck 2. A cargo refrigerating barge for a refrigerating vessel, which is intended to cool while keeping the same cooling temperature as in 10 and to secure the same refrigerating temperature. [Structure] The cargo hold 1 has the same length as the cargo refrigerating barge 10, and the intake of the return air to the cooler 4 after circulating the cold air is the upper center of the crowarm 7 And a slide-type lid, and a cargo refrigerating barge of a refrigerating ship, which is equipped on the front wall of the upper deck 2 and on the lower sides of the Clararm 7 on both sides.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to the arrangement of a cargo refrigerating barge of a refrigerating ship, and more particularly to the arrangement of a cargo refrigerating compartment integrated with a cargo hold opening and the structure of a return air intake port.

[0002]

[Prior art]

 Conventionally, the arrangement and structure of the cargo hold mouth of a cargo refrigerating barge that is in the same section as this type of cargo hold barge is as follows: on the upper deck, on the front and rear of the horizontal bulkhead of the cargo barge. Since a deck store is installed, it is shorter than the horizontal bulkheads in the cargo refrigeration barge, and therefore the cargo hold is generally shorter than the length of the cargo barge.

[0003]

[Problems to be solved by the device]

 According to the conventional technique, the cold air blown out from the cooler in the kuraram is convected in the cargo refrigeration compartment while flowing through the air passage on the floor of the cargo refrigeration compartment, and then again in the clarar compartment. Although it is inhaled from the return air intake port at the top of the cargo room, sufficient cold air does not circulate in the cargo hold mouth, causing a temperature difference between the bottom of the cargo refrigeration bar and the cargo hold mouth, and the cargo is transported. However, there was a problem that damage to the refrigerated cargo was caused.

For this reason, there are cases in which ducts for cold air are arranged in the front and rear of the cargo hold mouth, and cold air circulation fans are installed in the ducts. However, due to heat radiation from the electric motor driving the cold air circulation fan, On the contrary, there are problems that the temperature rises and the volume of the cargo refrigerating compartment decreases due to the arrangement of the cold air circulation duct.

The present invention has been made in view of the above problems of the conventional technology, and the purpose thereof is even in a cargo refrigerating compartment integrated with a cargo hold. An object of the present invention is to provide a freight refrigerating compartment in which there is no temperature difference between the bottom of the freight refrigerating compartment and the cargo hold mouth and the volume of the freight refrigerating compartment is not reduced.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the cargo refrigerating compartment of the cargo refrigerating barge which is integrated with the cargo port of the present invention, the length of the cargo refrigerating barrage should be the same as that of the cargo refrigerating barge, A return air inlet to the circulation curler is provided in the central portion of the upper portion of the curler and the front wall of the lower deck on both sides of the upper deck equipped with a sliding lid. Is.

[0007]

[Action]

 The length of the cargo hold will be secured over the entire bulkhead in the cargo hold. Therefore, the cold air blown out from the cooler in the refrigerated cargo area flows through the air passage on the floor and rises, and goes to the return air intake port of the cooler.

In the refrigerated cargo area, a slide-type lid provided at a return air intake port on the front wall of the clarum below the upper deck of both sides controls the amount of cold air by partially opening and closing the lid.

[0009]

【Example】

 Examples will be described with reference to the drawings.

1 to 3, the cargo refrigerating compartment 1 of the cargo refrigerating barge 10 that is integrated with the cargo refrigerating compartment 1 is an entire area in the longitudinal direction of the cargo refrigerating compartment 10 of the ship. It is arranged on the upper deck 2 occupying the center portion of the hull in the width direction.

A return air intake port 5 with a slide-type lid is fixedly provided on both sides of the upper deck 2 and the lower port of the cargo refrigeration compartment 3, and the return air intake is also performed on the upper portion of the clarum in the cargo hold opening. Fix mouth 6.

When there is a temperature difference between the temperature inside the cargo hold 1 in the cargo refrigeration compartment 3 and the ambient temperature below the upper deck 2, a return air inlet with a sliding lid on both lower sides of the upper deck 2 is provided. The intake amount of the return air is controlled by partially opening and closing the slide type lid of No. 5, and the temperature in the cargo refrigerating compartment 3 is kept uniform.

[0013]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. Since the return air intakes on both sides of the upper deck are equipped with sliding lids, it is possible to control the return air intake air volume at the cargo hold by partially opening and closing the lids, and to control the temperature inside the cargo refrigeration compartment. Keep uniform and prevent cargo damage of refrigerated cargo.
