Abstract
This air conditioning device (100) comprises: at least one first branch unit (10b, 10c); at least one second branch unit (10a); a plurality of indoor units (50a, 50b, 50c); a forward main pipe (61) and a return main pipe (62); and a plurality of forward branch pipes (51a, 51b, 51c) and a plurality of return branch pipes (52a, 52b, 52c). An intermediate heat exchanger (43) is configured such that heat exchange is performed between a refrigerant flowing through a first refrigerant pipe path (R1) and a heat medium flowing through a first pipe path (C1). A first heat exchanger (12) is configured such that heat exchange is performed between the heat medium flowing through the first pipe path (C1) and a refrigerant flowing through a second refrigerant pipe path (R2). A second heat exchanger (22) is configured such that heat exchange is performed between a heat medium flowing through a second pipe path (C2) and the refrigerant flowing through the second refrigerant pipe path (R2).
