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 (1). The heat pump cycle is configured to set both of a high-pressure side pressure reducing device (13) and a low-pressure side pressure reducing device (16b, 17, 18) 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 (11) to an outside heat exchanger (20) based on the operation modes of the air conditioning device (1). |
