Abstract
(EN)
According to the present invention, a refrigerant flow path switching unit (4) is provided between a heat source unit (2) and a utilization unit (3) and switches the flow of a refrigerant at the utilization unit (3). The refrigerant flow path switching unit (4) has: flow path switching valves (46, 47); and a case (120) that houses the flow path switching valves (46, 47). Maintenance openings (132, 133, 134) are formed in at least two side surfaces (123, 125, 126) of side surfaces (123–126) of the case (120).

Selon la présente invention, une unité de commutation de trajet d'écoulement de fluide frigorigène (4) est disposée entre une unité de source de chaleur (2) et une unité d'utilisation (3) et assure la commutation de l'écoulement d'un fluide frigorigène au niveau de l'unité d'utilisation (3). L'unité de commutation de trajet d'écoulement de fluide frigorigène (4) comprend: des vannes de commutation de trajet d'écoulement (46, 47); et un boîtier (120) qui loge les vannes de commutation de trajet d'écoulement (46, 47). Des ouvertures de maintenance (132, 133, 134) sont formées dans au moins deux surfaces latérales (123, 125, 126) de surfaces latérales (1231,126) du boîtier (120).
