Vehicle temperature management apparatus

A vehicle temperature management apparatus comprising:

• a refrigerant circulation circuit for circulating a refrigerant that exchanges heat with a temperature adjustment target device mounted on a vehicle;
• a chiller heat exchange channel provided in the refrigerant circulation circuit and including a chiller that cools the refrigerant;
• a heater heat exchange channel provided in parallel to the chiller heat exchange channel in the refrigerant circulation circuit, the heater heat exchange channel including a heater configured to heat the refrigerant;
• a channel selection section configured to select at least one of the chiller heat exchange channel and the heater heat exchange channel as a channel of the refrigerant in the refrigerant circulation circuit;
• a switching control section configured to control the channel selection section such that the channel selection section selects at least one of the chiller heat exchange channel and the heater heat exchange channel;
• and
• an operation control section configured to control an operation of the chiller,
• the switching control section configured to control, when the heater heat exchange channel is selected as the channel of the refrigerant, the channel selection section such that the channel selection section selects the heater heat exchange channel and the chiller heat exchange channel as the channel of the refrigerant, and the operation control section does not operate the chiller.

A vehicle temperature management apparatus comprising:

• a refrigerant circulation circuit for circulating a refrigerant that exchanges heat with a temperature adjustment target device mounted on a vehicle;
• a chiller heat exchange channel provided in the refrigerant circulation circuit and including a chiller that cools the refrigerant;
• a radiator heat exchange channel provided in parallel to the chiller heat exchange channel in the refrigerant circulation circuit, the radiator heat exchange channel including a radiator that causes outside air and the refrigerant to exchange heat therebetween to thereby radiate heat from the refrigerant to the outside air;
• a heater heat exchange channel provided in parallel to the chiller heat exchange channel in the refrigerant circulation circuit, the heater heat exchange channel including a heater configured to heat the refrigerant;
• a channel selection section configured to select at least one of the chiller heat exchange channel, the radiator heat exchange channel, and the heater heat exchange channel as a channel of the refrigerant in the refrigerant circulation circuit;
• a switching control section configured to control the channel selection section such that the channel selection section selects at least one of the chiller heat exchange channel, the radiator heat exchange channel, and the heater heat exchange channel;
• and
• an operation control section configured to control an operation of the chiller,
• the switching control section configured to control, when the radiator heat exchange channel or the heater heat exchange channel is selected as the channel of the refrigerant, the channel selection section such that the channel selection section further selects the chiller heat exchange channel, and the operation control section does not operate the chiller.
