Original Abstract Submitted
A heat pump cycle apparatus includes a compressor, an upstream branch part, a heating unit, an outside air heat exchanger, an upstream decompression unit, a downstream decompression unit, a bypass passage, and a bypass-side flow rate adjusting unit. In a heating mode of heating a heating target, a refrigerant decompressed in the upstream decompression unit flows into the outside air heat exchanger, and the refrigerant is caused to absorb heat of outside air in the outside air heat exchanger. In a defrosting mode of removing frost on the outside air heat exchanger, one refrigerant branched at the upstream branch part is caused to flow into the outside air heat exchanger to dissipate heat, and the refrigerant decompressed at the downstream decompression unit and the refrigerant flowing out of the bypass-side flow rate adjusting unit are mixed and sucked into the compressor.
