Heat pump cycle apparatus

A heat pump cycle apparatus including at least one utilization-side heat exchanger and at least one non-utilization-side heat exchanger, comprising:

• a refrigerant container disposed in series with the non-utilization-side heat exchanger, receiving a refrigerant, and flowing out a liquid component of the refrigerant;
• a first control valve disposed between the non-utilization-side heat exchanger and the refrigerant container, the first control valve causing the non-utilization-side heat exchanger to function as an evaporator when the refrigerant flows from the refrigerant container to the non-utilization-side heat exchanger, and causing the non-utilization-side heat exchanger to function as a condenser when the refrigerant flows from the non-utilization-side heat exchanger to the refrigerant container;
• and
• a switching valve as a part of a switching mechanism which switches the refrigerant flow direction passing through the non-utilization-side heat exchanger and the refrigerant container, wherein
• the utilization-side heat exchanger has a cooling heat exchanger and a heating heat exchanger, and wherein the heat pump cycle apparatus further comprises:
• a second control valve which is provided downstream of the heating heat exchanger;
• a third control valve which is provided upstream of the cooling heat exchanger;
• and
• a bidirectional passage through which the refrigerant can flow in both directions, the bidirectional passage is a passage in which the flow direction of the refrigerant is switched by the switching valve, wherein
• the switching valve, the refrigerant container, the first control valve, and the non-utilization-side heat exchanger are provided between the second control valve and the third control valve, and wherein
• the outdoor heat exchanger, the first control valve, and the refrigerant container are arranged in series in this order in the bidirectional passage.
