A heat pump cycle is capable of switching an operation mode to a cooling operation mode, a heating operation mode and a dehumidifying-heating operation mode, and is applicable to an air conditioning device. The heat pump cycle is configured to set both of a high-pressure side pressure reducing device and a low-pressure side pressure reducing device-in a throttled state and a fully open state. In this way, the heat pump cycle realizes cooling, heating, and dehumidifying-heating by a simple structure without providing separate refrigerant flow passages extended from a compressor to an outside heat exchanger based on the operation modes of the air conditioning device. |
