摘要:
A first heat exchanger implements heat exchange between refrigerant and atmosphere. A second heat exchanger implements heat exchange between the refrigerant and air directed to an interior of the vehicle. A third heat exchanger downstream of the second heat exchanger implements heat exchange between the refrigerant and the air directed to the interior of the vehicle. A four-way valve connected among a refrigerant flow restricting device, the first heat exchanger, the second heat exchanger, and the third heat exchanger for changing a flow path of the refrigerant. A bypass device allows the refrigerant to selectively flow through the second heat exchanger and bypass the second heat exchanger. During a first mode of operation, the refrigerant is circulated sequentially through a compressor, the third heat exchanger, the four-way valve, the first heat exchanger, the refrigerant flow restricting device, the four-way valve, the second heat exchanger, and the compressor. During a second mode of operation, the refrigerant is circulated sequentially through the compressor, the third heat exchanger, the four-way valve, the refrigerant flow restricting device, the first heat exchanger, the four-way valve, the second heat exchanger, and the compressor. During a third mode of operation, the refrigerant is circulated sequentially through the compressor, the third heat exchanger, the four-way valve, the refrigerant flow restricting device, the first heat exchanger, the four-way valve, and the compressor while being allowed by the bypass device to bypass the second heat exchanger.
