Abstract

A refrigeration cycle apparatus (100) includes a bridge circuit (40). The bridge circuit (40) keeps a traveling direction of a refrigerant (R) the same in both a cold heat utilization operation and a hot heat utilization operation. The bridge circuit (40) includes a first flow path (AB), a second flow path (BC), a third flow path (DC), a fourth flow path (AD), and a first check valve (41), and a second check valve (42), a third check valve (43), and a fourth check valve (44) provided in the first flow path (AB), the second flow path (BC), the third flow path (DC), and the fourth flow path (AD), respectively. A flow path resistance of the fourth flow path (AD) is larger than a flow path resistance of the first flow path (AB), or a flow path resistance of the third flow path (DC) is larger than a flow path resistance of the second flow path (BC).
