Beschreibung
Zusammenfassung:	A refrigerant flow path switching unit (4) is a unit provided between a heat source unit (2) and a utilization unit (3) and configured to switch a refrigerant flow in the utilization unit (3). The refrigerant flow path switching unit (4) has a flow path switching valve (46, 47) and a case (120) housing the flow path switching valve (46, 47). Maintenance openings (132, 133, 134) are formed on at least two side surfaces (123, 125, 126) of side surfaces (123 to 126) of the case (120).
