Description
本発明は、船舶の糧食庫用冷凍装置及び船舶の糧食庫用冷凍装置の取付方法に関し、特に、庫内側から取付作業を行うための構造及び方法に係るものである。 The present invention relates to a refrigeration apparatus for ship food storage and a method for mounting a refrigeration apparatus for ship food storage, and particularly relates to a structure and method for performing an attachment operation from the inside of the storage.
従来、船舶には、航海中の乗組員の食糧を保存するために糧食庫が設けられ、該糧食庫には、庫内を冷却する冷凍装置が設けられている(例えば、下記特許文献1を参照)。船舶の糧食庫用冷凍装置は、陸上においてプレハブ冷凍庫等に取り付けられる冷凍装置と同様に構成され、圧縮機及び水冷式の凝縮器を有するコンデンシングユニットと膨張機構が組み込まれた膨張弁パネルとを備えて庫外に設置される熱源側ユニットと、蒸発器と利用側ファンとがケーシング内に収容されて庫内に設置される利用側ユニットとを有している。圧縮機と水冷式の凝縮器と膨張機構と蒸発器とが順に接続されて冷媒回路を構成し、該冷媒回路に冷媒が循環して冷凍サイクルが行われることによって蒸発器において庫内の空気が冷却される。なお、熱源側ユニットの水冷式の凝縮器には、冷却水配管が接続され、凝縮熱を冷却水に放熱している。 2. Description of the Related Art Conventionally, a ship is provided with a food storage for preserving the food of crew members on the voyage, and the food storage is provided with a freezing device that cools the interior of the ship (for example, Patent Document 1 below). reference). A refrigeration apparatus for a ship's food storage is configured in the same manner as a refrigeration apparatus attached to a prefabricated freezer etc. on land, and includes a condensing unit having a compressor and a water-cooled condenser, and an expansion valve panel incorporating an expansion mechanism. And a heat source side unit installed outside the storage, and a use side unit in which the evaporator and the use side fan are housed in the casing and installed in the store. A compressor, a water-cooled condenser, an expansion mechanism, and an evaporator are connected in order to form a refrigerant circuit, and the refrigerant circulates in the refrigerant circuit and a refrigeration cycle is performed. To be cooled. A cooling water pipe is connected to the water-cooled condenser of the heat source side unit, and the heat of condensation is radiated to the cooling water.
ところで、従来の船舶の糧食庫用冷凍装置では、熱源側ユニットが、利用側ユニットから離れた位置に設けられていたため、熱源側ユニットと利用側ユニットとに跨がって設けられる冷媒回路の接続用配管が長くなり、また、冷却水配管を施工する事が必要であったため、施工工数が増大すると共に施工コストが嵩むという問題があった。また、狭い船内では熱源側ユニットの設置スペースの確保が困難であった。 By the way, in the conventional refrigeration apparatus for ship food storage, since the heat source side unit is provided at a position away from the use side unit, the connection of the refrigerant circuit provided across the heat source side unit and the use side unit Since the pipe for construction became long and it was necessary to construct the cooling water pipe, there was a problem that the construction man-hour increased and the construction cost increased. Moreover, it was difficult to secure the installation space for the heat source unit in a narrow ship.
これに対し、空冷式の凝縮器を用いると共に、熱源側ユニットと利用側ユニットとを一体に形成した冷凍装置を設けることが考えられる。陸上用のプレハブ冷凍庫等においても一体型の冷凍装置が設けられているが、陸上では上方又は周囲に大きなスペースを確保することができるため、プレハブ冷凍庫の天井面や側壁面に開口を形成し、庫外から一体型の冷凍装置の利用側ユニットを開口に挿通して庫内に位置させた状態で、一体型の冷凍装置を天井又は側壁面に庫外側から取り付けている(例えば、上記特許文献2を参照)。 On the other hand, it is conceivable to use an air-cooled condenser and to provide a refrigeration apparatus in which a heat source side unit and a use side unit are integrally formed. An integrated refrigeration system is also provided in on-shore prefabricated freezers, etc., but on land, because a large space can be secured above or around, an opening is formed on the ceiling surface or side wall surface of the prefabricated freezer, The integrated refrigeration apparatus is attached to the ceiling or the side wall surface from the outside in a state where the use side unit of the integrated refrigeration apparatus is inserted into the opening from the outside and positioned in the storage (for example, the above-mentioned patent document 2).
しかしながら、船舶では、波による揺動等の大きな荷重を支えるために巨大な梁が設けられている。また、糧食庫は庫内への侵入口にあたる扉以外の天井及び側壁のほとんどを船体構造である鉄板に覆われている。そのため、陸上用のプレハブ冷凍庫のように、糧食庫の天井に一体型の冷凍装置を設置するためのスペースが確保できない。また、糧食庫は、船内の限りあるスペースに設置されるため、糧食庫の側方のスペースも広く確保できない。そのため、糧食庫の側壁に一体型の冷凍装置の設置スペースを確保できたとしても、糧食庫の側方のスペースが狭いために糧食庫の庫外側からの着脱作業及び糧食庫の庫外側からのメンテナンス作業が非常に困難なものとなっていた。そこで、船舶の糧食庫用冷凍装置として、熱源側ユニットと利用側ユニットとが一体に形成された冷凍装置を、糧食庫の庫内側から着脱可能に構成することが望まれていた。 However, in ships, huge beams are provided to support large loads such as rocking caused by waves. Moreover, the food storage is covered with the iron plate which is a hull structure, most of the ceiling and the side wall other than the door corresponding to the entrance to the warehouse. For this reason, it is not possible to secure a space for installing an integrated refrigeration apparatus on the ceiling of the food storage like a land-based prefabricated freezer. In addition, since the food storage is installed in a limited space on the ship, it is not possible to secure a wide space on the side of the food storage. Therefore, even if the installation space for the integrated refrigeration system can be secured on the side wall of the food storage room, the space on the side of the food storage room is narrow, so the attachment / detachment work from the outside of the food storage room and the outside of the food storage room Maintenance work was very difficult. Therefore, it has been desired to configure a refrigeration apparatus in which a heat source side unit and a use side unit are integrally formed as a refrigeration apparatus for a ship food storage so as to be detachable from the inside of the food storage.
本発明は、斯かる点に鑑みてなされたものであり、糧食庫内から着脱が可能な船舶の糧食庫用冷凍装置及び船舶の糧食庫用冷凍装置を提供することを目的とする。 This invention is made | formed in view of such a point, and it aims at providing the refrigeration apparatus for ship's food storage and the refrigeration apparatus for food supply of a ship which can be attached or detached from the inside of a food storage.

That is, the release operation for releasing the fixed state of the fixing portion (50) and the extraction operation of the refrigeration apparatus for food storage (10) are performed in the storage, so that the refrigeration apparatus for food storage (10) becomes the food storage (1). Removed from the side wall (5). In this way, the refrigeration apparatus for food storage (10) is configured so that the attachment / detachment work to the side wall (5) of the food storage (1) of the food storage refrigeration apparatus (10) can be performed in the storage. The maintenance work that requires the attaching / detaching work can be performed in the cabinet.
第2の発明は、第1の発明において、上記固定部(50)は、上記設置位置において、上記糧食庫(1)の側壁(5)内面に沿って上記開口(6)の外方へ延びて上記側壁(5)に固定される板状体を有している。 In a second aspect based on the first aspect, the fixing portion (50) extends outward from the opening (6) along the inner surface of the side wall (5) of the food storage (1) at the installation position. And a plate-like body fixed to the side wall (5).
第2の発明では、ケーシング(40)に設けられ、設置位置において糧食庫(1)の側壁(5)内面に沿って開口(6)の外方へ延びる固定部(50)の板状体を、糧食庫(1)の側壁(5)に固定することによって、糧食庫用冷凍装置(10)が糧食庫(1)の側壁(5)内面に固定される。 In the second invention, the plate-like body of the fixing portion (50) provided on the casing (40) and extending outward of the opening (6) along the side wall (5) inner surface of the food storage (1) at the installation position is provided.

ところで、熱源側ユニット(20)が糧食庫(1)の側壁(5)の開口(6)に挿通された状態で糧食庫用冷凍装置(10)を糧食庫(1)の側壁(5)に取り付けることとすると、熱源側ユニット(20)の凝縮器(22)において空気に放出される高圧冷媒の熱が庫内の空気に伝達されて庫内の空気を加熱するおそれがある。 By the way, with the heat source unit (20) inserted through the opening (6) of the side wall (5) of the food storage (1), the refrigeration unit for food storage (10) is connected to the side wall (5) of the food storage (1). If attached, the heat of the high-pressure refrigerant released to the air in the condenser (22) of the heat source side unit (20) may be transferred to the air in the warehouse to heat the air in the warehouse.
これに対し、第3の発明では、設置位置において熱源側ユニット(20)から庫内への熱伝達が抑制されるように、熱源側ケーシング(41)内に断熱部材(25)が設けられている。そのため、庫内の冷却された空気が熱源側ユニット(20)の熱によって加熱されない。また、第4の発明では、熱源側ユニット(20)内の庫内側端部に断熱材料を設置するだけで断熱部材(25)が形成されている。 In contrast, in the third aspect of the invention, the heat insulating member (25) is provided in the heat source side casing (41) so that heat transfer from the heat source side unit (20) to the interior is suppressed at the installation position. Yes. Therefore, the cooled air in the warehouse is not heated by the heat of the heat source side unit (20). Moreover, in the 4th invention, the heat insulation member (25) is formed only by installing a heat insulation material in the warehouse inner side edge part in a heat-source side unit (20).
第5の発明は、第1乃至第4のいずれか1つの発明において、上記熱源側ケーシング(41)は、筺状に組み立てられた複数のパネル部材(44)と、上記設置位置において上記開口(6)内に位置する部分に設けられ、上記複数のパネル部材(44)を内側から支持する枠状部材とを有している。 According to a fifth invention, in any one of the first to fourth inventions, the heat source side casing (41) includes a plurality of panel members (44) assembled in a bowl shape and the opening ( 6) A frame-like member that is provided in a portion located inside and supports the plurality of panel members (44) from the inside.
第5の発明では、設置位置において開口(6)内に位置して熱源側ケーシング(41)の複数のパネル部材(44)を内側から支持する枠状部材により、熱源側ケーシング(41)の設置位置において開口(6)内に位置する部分の剛性が増大する。 In the fifth invention, the heat source side casing (41) is installed by the frame-like member that is located in the opening (6) at the installation position and supports the plurality of panel members (44) of the heat source side casing (41) from the inside. In position, the rigidity of the part located in the opening (6) increases.
第6の発明は、第5の発明において、上記ケーシング(40)は、庫外側端部から庫内側端部まで延び、上記枠状部材の角部に固定された桁部材を有している。 In a sixth aspect based on the fifth aspect, the casing (40) has a girder member that extends from the outer end to the inner end and is fixed to the corner of the frame member.
第6の発明では、枠状部材の角部に固定され、ケーシング(40)の庫外側端部から庫内側端部まで延びる桁部材により、ケーシング(40)の剛性が増大する。 In 6th invention, the rigidity of a casing (40) increases by the girder member fixed to the corner | angular part of a frame-shaped member, and extending from the warehouse outer side edge part of a casing (40) to a warehouse inner side edge part.
第7の発明は、第1乃至第6のいずれか1つの発明において、上記熱源側ケーシング(41)には、上記凝縮器(22)と熱交換した空気を吹き出す吹出口(27)が、上記熱源側ユニット(20)の上記開口(6)への挿通方向における上記固定部(50)との距離が120mm以上となる位置に形成されている。 According to a seventh invention, in any one of the first to sixth inventions, the heat source side casing (41) includes the air outlet (27) for blowing out the air heat-exchanged with the condenser (22). The heat source side unit (20) is formed at a position where the distance from the fixing portion (50) in the insertion direction to the opening (6) is 120 mm or more.
第7の発明では、熱源側ケーシング(41)に、凝縮器(22)と熱交換した空気を吹き出す吹出口(27)が形成され、該吹出口(27)が、熱源側ユニット(20)の開口(6)への挿通方向における固定部(50)との距離が120mm以上となる位置に設けられている。 In 7th invention, the blower outlet (27) which blows off the air heat-exchanged with the condenser (22) is formed in the heat source side casing (41), and this blower outlet (27) is the heat source side unit (20). It is provided at a position where the distance to the fixed portion (50) in the insertion direction to the opening (6) is 120 mm or more.
ところで、糧食庫(1)の側壁(5)を構成する断熱パネルの厚みは、糧食庫(1)毎に異なり、1種類ではない。また、糧食庫用冷凍装置(10)は、上述のように、庫内側から熱源側ユニット(20)を開口(6)に挿入して庫外側へ押し出すことで設置位置に配置することとしているため、配置作業中に、庫外側の熱源側ユニット(20)の吹出口(27)が庫外に位置しているか否かが視認できない。 By the way, the thickness of the heat insulation panel which comprises the side wall (5) of a food storage (1) differs for every food storage (1), and is not one type. In addition, as described above, the refrigeration apparatus for food storage (10) is arranged at the installation position by inserting the heat source side unit (20) into the opening (6) from the inside and pushing it out to the outside as described above. During the placement work, it cannot be visually confirmed whether or not the air outlet (27) of the heat source side unit (20) outside the warehouse is located outside the warehouse.
しかしながら、第7の発明では、通常、糧食庫(1)の側壁として用いられる断熱パネルの厚さの最大値が100mm程度であることに鑑みて、熱源側ケーシング(41)に形成された吹出口(27)を、熱源側ユニット(20)の開口(6)への挿通方向における固定部材(52)からの距離が120mm以上となる位置に形成することとしている。そのため、庫外側に位置する部分を視認できなくとも、熱源側ユニット(20)の吹出口(27)は、常に庫外に位置することとなる。 However, in the seventh aspect of the invention, in view of the fact that the maximum value of the thickness of the heat insulating panel used as the side wall of the food storage (1) is normally about 100 mm, the air outlet formed in the heat source side casing (41) (27) is formed at a position where the distance from the fixing member (52) in the insertion direction to the opening (6) of the heat source side unit (20) is 120 mm or more. Therefore, even if the part located outside the warehouse cannot be visually recognized, the air outlet (27) of the heat source side unit (20) is always located outside the warehouse.
