Title
(EN) HEAT EXCHANGE UNIT
(FR) UNITÉ D'ÉCHANGE DE CHALEUR
(JA) 熱交換ユニット
Abstract
(EN)
Provided is a heat exchange unit utilizing a flammable refrigerant, which enables highly reliable detection of refrigerant leakage. This heat exchange unit exchanges heat between a flammable refrigerant and a liquid medium which is delivered to a utilization-side facility, thereby cooling and/or heating the liquid medium. The heat exchange unit is provided with a heat exchanger, a casing, a drain pan (80) which is disposed at the lower part of the casing, below the heat exchanger, and a gas detection sensor (70). In the heat exchanger, heat is exchanged between the refrigerant and the liquid medium. The casing houses the heat exchanger. The drain pan has a bottom plate (82) and a sidewall (84) which extends upward from the bottom plate. A first gas detection sensor detects whether or not a refrigerant gas is present in the space (Si) of the drain pan, which is located above the bottom plate of the drain pan and below the upper end of the sidewall of the drain pan.

L'invention concerne une unité d'échange de chaleur qui utilise un fluide frigorigène inflammable et qui permet une détection hautement fiable de fuite de fluide frigorigène. Cette unité d'échange de chaleur échange de la chaleur entre un fluide frigorigène inflammable et un milieu liquide qui est délivré à une installation côté utilisation, ce qui permet de refroidir et/ou de chauffer le milieu liquide. L'unité d'échange de chaleur est pourvue d'un échangeur de chaleur, d'un carter, d'un bac de vidange (80) qui est disposé au niveau de la partie inférieure du carter, sous l'échangeur de chaleur, et d'un capteur de détection de gaz (70). Dans l'échangeur de chaleur, la chaleur est échangée entre le fluide frigorigène et le milieu liquide. Le carter loge l'échangeur de chaleur. Le bac de vidange comporte une plaque inférieure (82) et une paroi latérale (84) qui s'étend vers le haut à partir de la plaque inférieure. Un premier capteur de détection de gaz détecte si un gaz frigorigène est présent ou non dans l'espace (Si) du bac de vidange, qui est situé au-dessus de la plaque inférieure du bac de vidange et au-dessous de l'extrémité supérieure de la paroi latérale du bac de vidange.
