1. A refrigerant circuit comprising:
a reserve tank comprising:
a plurality of chambers, including a first chamber, a second chamber, and at least one intermediate chamber;
a first inflow port connected to the first chamber;
a first outflow port connected to the first chamber;
a second inflow port connected to the second chamber;
a second outflow port connected to the second chamber; and
a plurality of partition walls separating the chambers, including a first partition wall and a second partition wall, the first partition wall separating between the first chamber and the at least one intermediate chamber, the second partition wall separating between the second chamber and the at least one intermediate chamber, each of the partition walls being provided with a corresponding one of a plurality of refrigerant flow ports, the refrigerant flow ports including a first refrigerant flow port provided in the first partition wall and a second refrigerant flow port provided in the second partition wall, and being configured such that refrigerant flows from the first chamber to the second chamber via the at least one intermediate chamber and the refrigerant flow ports, and a specific refrigerant flow port including a first through hole and a second through hole that pass through a specific partition wall and are separated from each other, the specific refrigerant flow port being the refrigerant flow port provided in the specific partition wall among the partition walls; and
a switching valve configured to switch flow paths of refrigerant flowing through the first inflow port, the first outflow port, the second inflow port, and the second outflow port, and configured to switch the flow paths between a first state and a second state, the first state being a state in which the refrigerant flows from the first inflow port to the first outflow port and the refrigerant also flows from the second inflow port to the second outflow port, and the second state being a state in which the refrigerant flows from the first inflow port to the second outflow port.
