Air-conditioning apparatus

An air-conditioning apparatus, comprising:

• a refrigerant circuit in which a compressor, a first heat exchanger, an expansion valve, and a second heat exchanger are connected by pipes, and through which refrigerant circulates;
• and
• a fluid circuit through which fluid circulates, the fluid exchanging heat, in the second heat exchanger, with the refrigerant circulating through the refrigerant circuit,
• the fluid circuit including
• a first branch circuit that connects a branching portion and a connecting portion, wherein the branching portion branches from a conduit downstream of the second heat exchanger, and wherein the connecting portion is farther downstream in a direction of fluid flow than the branching portion, and
• a second branch circuit that connects a branching portion and a connecting portion, wherein the branching portion connected to the second branch circuit branches at a portion farther downstream than the connecting portion connected to the first branch circuit, and wherein the connecting portion connected to the second branch circuit is farther downstream in the direction of fluid flow than the branching portion connected to the second branch circuit,
• the first branch circuit being provided with a third heat exchanger that exchanges heat between fluid flowing through the fluid circuit and outdoor air,
• the second branch circuit being provided with a heat storage tank that stores fluid having exchanged heat with outdoor air in the third heat exchanger.
