PROBLEM TO BE SOLVED: To provide a refrigerant circuit device capable of improving heat exchanging efficiency by increasing the amount of air passing among fin members. SOLUTION: In this refrigerant circuit device including a refrigerant circuit 10 constituted by successively connecting inner heat exchangers 24 respectively disposed inside of object rooms and evaporating a refrigerant supplied thereto to cool the internal atmosphere of the room in which it is disposed, a compressor 22 for sucking and compressing the refrigerant evaporated by each of the inner heat exchangers 24, and an outdoor heat exchanger 22 to which the refrigerant compressed by the compressor 22 is introduced to be condensed, by refrigerant pipes 25, each inner heat exchanger 24 includes a heat transfer tube 241 constituting a refrigerant flow channel and bent in a meandering state, the fin members 242 arranged in parallel with each other between a pair of side plates 244 disposed in a state of being inserted into the heat transfer tube 241, and a closing member 243 for closing holes 245 formed on the side plates 244 for inserting the heat transfer tube 241.
