PROBLEM TO BE SOLVED: To provide a refrigerant circuit device capable of suppressing clogging of a refrigerant in an expanding mechanism and the like and improving heat exchanging efficiency by properly removing foreign matters even in a refrigerant circuit having a function as a heat pump. SOLUTION: This refrigerant circuit device including a main circuit 20 constituted by successively connecting inner heat exchangers 24, a compressor 21 and an outer heat exchanger 22, a branched introduction pathway 30 to which the compressed refrigerant is branched and introduced to be supplied to the indoor heat exchanger 24 disposed in a room to be heated, a radiation pathway 40 to which the refrigerant condensed by the inner heat exchanger 24 is introduced to supply the refrigerant to a gas cooler 41, a return pathway 50 for returning the refrigerant radiating heat at the gas cooler 41 to the main circuit 20, and a second capillary tube 52 for adiabatic expansion of the refrigerant radiating heat at the gas cooler 41, further includes a second strainer S2 disposed in a passing region of the refrigerant supplied to the second capillary tube 52 for removing foreign matters mixed in the refrigerant.
