A heat source-side refrigerant circuit (A) and a heat medium circuit (B) are cascade-connected so that heat source-side refrigerant and a heat medium exchange heat in an intermediate heat exchanger (15). The heat medium circuit (B) includes a relief valve (60), which is actuated when the heat source-side refrigerant flows into the heat medium circuit (B), to thereby expel the heat source-side refrigerant and the heat medium.
