Abstract

An aggregated channel switching unit is disposed between a heat source unit and a plurality of utilization units to switch flow of refrigerant in the refrigerant circuit. The aggregated channel switching unit including a plurality of first refrigerant pipes having switch valves, a plurality of second refrigerant pipes, and a casing accommodating the first and second pipes. The first and second pipes are aggregated as an assembly. The first pipes are connected to a high-low pressure gas communicating pipe and a suction gas communicating pipe extending from the heat source unit. The second refrigerant pipes are connected to a liquid communicating pipe extending from the heat source unit and a liquid pipe extending to the utilization units. Adjacent pairs of the first and second pipes extend approximately in parallel to each other at predetermined intervals in the assembly. The first and second pipes are alternately disposed in the assembly.
