Abstract
Description
トレーラ用冷凍装置(20)は、冷凍車両(10)の庫内空間(13)の空気を冷却するための冷却装置を構成している。図2に示すように、トレーラ用冷凍装置(20)は、冷媒が充填される冷媒回路(21)を備えている。冷媒回路(21)には、圧縮機(22)と凝縮器(23)と膨張弁(24)と蒸発器(25)とが接続されている。冷媒回路(21)では、冷媒が循環することで蒸気圧縮式の冷凍サイクルが行われる。凝縮器(23)の近傍には、庫外ファン(26)が設けられている。凝縮器(23)では、庫外ファン(26)によって搬送される庫外(室外)空気と冷媒とが熱交換する。蒸発器(25)の近傍には、庫内ファン(27)が設けられている。蒸発器(25)では、庫内ファン(27)によって搬送される庫内空気と冷媒とが熱交換する。蒸発器(25)は、トレーラ(11)の庫内空間(13)の空気を冷却するための冷却部を構成している。
前面カバー(32)は、庫外ケーシング(50)の前面に着脱自在に構成されている。前面カバー(32)は、幅方向(図3における左右方向)の中間部位が前方に膨出する弓形の板状部材で構成されている。前面カバー(32)は、幅方向両端の側辺部(32a,32a)が庫外ケーシング(50)に保持される。これにより、前面カバー(32)の背面と庫外ケーシング(50)の前面との間には、各種の構成機器(詳細は後述する)が収容される機器室(35,36)が形成される。
庫外ケーシング(50)は、トレーラ(11)の外側に設けられている。庫外ケーシング(50)は、アルミニウム材料で構成されている。庫外ケーシング(50)は、正方形板状のベース部(51)と、ベース部(51)の上方部位に形成される膨出部(52)とを有している(図3、図4、図6を参照)。
図6に示すように、庫内ケーシング(33)は、トレーラ(11)の庫内空間(13)に臨むように、庫外ケーシング(50)の背面側に設けられている。庫内ケーシング(33)は、例えばFRP(ガラス繊維強化プラスチック)材料で構成されている。なお、庫内ケーシング(33)を、他の樹脂材料や金属材料等で構成することもできる。庫内ケーシング(33)は、庫外ケーシング(50)の背面に沿うような形状をしている。
本実施形態のトレーラ用冷凍装置(20)では、上述のように、トレーラ(11)の開放部(14)にケーシングユニット(31)が取り付けられる。ケーシングユニット(31)とトレーラ(11)の開放部(14)の取り付け構造の詳細について、図7を参照しながら説明する。なお、図7は、トレーラ(11)の左右の幅方向の両側にある側縁部(14a)(図2を参照)の近傍の水平断面を拡大して示すものである。
次に、トレーラ用冷凍装置(20)の運転動作について、図6及び図8を参照しながら説明する。
上記実施形態では、トレーラ(11)の開放部(14)の両側の側縁部(14a)と、庫外ケーシング(50)との各取り付け部(60)において、溝部(61)に凸部(62)を嵌合させるようにしている。これにより、上記実施形態では、冷凍車両(10)の走行中(特に冷凍車両(10)が曲がる際)において、トレーラ(11)の横手方向に作用する応力に対して、強度を向上できる。このため、ボルト(16)の本数を減らす等によって、ケーシングユニット(31)をトレーラ(11)に取り付けるための取付構造を簡素化できる。
上記実施形態については、以下のような構成としてもよい。
13 庫内空間
14 開放部
14a 側縁部
17 上縁部
18 下縁部
25 蒸発器(冷却部)
