Title (EN) EVAPORATOR UNIT
(FR) UNITÉ À ÉVAPORATEURS
(JA) 蒸発器ユニット
Abstract:
(EN) An evaporator unit, provided with an ejector (15), a discharge-side evaporator (17), and a suction-side evaporator (18). The discharge-side evaporator has a plurality of discharge-side tubes (71) and a discharge-side tank (72, 73). A discharge-side distribution space (72b) for distributing a refrigerant to a plurality of the discharge-side tubes is formed in the discharge-side tank. A partition plate (93) is disposed in the discharge-side distribution space. The partition plate partitions the discharge-side distribution space into an ejector-side distribution space (721b) and a tube-side distribution space (722b). Communication holes (93d) communicating the ejector-side distribution space and the tube-side distribution space with each other are formed in the partition plate. The partition plate has a first region (EF1), a second region (EF2), a third region (EF3), a fourth region (EF4), and a fifth region (EF5). The opening area of the communication holes in each of the first region, the third region, and the fifth region is larger than the opening area of the communication holes in the second region and the fourth region.
(FR) L'invention concerne une unité à évaporateurs, pourvue d'un éjecteur (15), d'un évaporateur du côté décharge (17) et d'un évaporateur du côté aspiration (18). L'évaporateur côté décharge comporte une pluralité de tubes côté décharge (71) et un réservoir côté décharge (72,73). Un espace de distribution côté décharge (72b) pour distribuer un réfrigérant à la pluralité de tubes côté décharge est formé dans le réservoir côté décharge. Une plaque de séparation (93) est disposée dans l'espace de distribution côté décharge. La plaque de séparation divise l'espace de distribution côté décharge en un espace de distribution côté éjecteur (721b) et un espace de distribution côté tube (722b). L'espace de distribution côté éjecteur communique avec l'espace de distribution côté tube à travers des trous de communication (93d) formés dans la plaque de séparation. La plaque de séparation comporte une première région (EF1), une deuxième région (EF2), une troisième région (EF3), une quatrième région (EF4) et une cinquième région (EF5) La zone d'ouverture des trous de communication dans les première, troisième, et cinquième région est plus grande que la zone d'ouverture des trous de communication dans les deuxième et quatrième région.
(JA) 蒸発器ユニットは、エジェクタ(15)、吐出側蒸発部(17)、および吸引側蒸発部(18)を備える。吐出側蒸発部は、複数の吐出側チューブ(71)と吐出側タンク(72、73)を有する。吐出側タンク内には、冷媒を複数の吐出側チューブへ分配する吐出側分配空間(72b)が形成されている。吐出側分配空間の内部には仕切板(93)が配置され、仕切板は、吐出側分配空間を、エジェクタ側分配空間(721b)とチューブ側分配空間(722b)とに仕切っている。仕切板には、エジェクタ側分配空間とチューブ側分配空間とを連通させる連通穴(93d)が形成されている。仕切板は、第1領域(EF1)、第2領域(EF2)、第3領域(EF3)、第4領域(EF4)、第5領域(EF5)を有する。第1領域、第3領域、第5領域における連通穴の開口面積はそれぞれ、第2領域、第4領域における連通穴の開口面積よりも大きくなっている。
