Temperature control system for a motor vehicle controlling the temperature of drivetrain components of a motor vehicle

A system, comprising an evaporator arranged directly upstream of a heat exchanger;

• a first valve configured to control air flow from the evaporator to a vehicle interior;
• a second valve configured to control air flow from the evaporator to the heat exchanger;
• a third valve configured to control air flow from the heat exchanger to the vehicle interior and to a vehicle environment;
• and
• a controller with instructions stored on memory thereof that when executed enable the controller to:
• select one or more of a plurality of operating modes in response to a vehicle interior temperature request and a drivetrain component temperature;
• wherein the instructions cause the controller to select a first mode in response to an ambient temperature being less than a lower threshold ambient temperature and the drivetrain component temperature being less than an upper threshold component temperature, the first mode comprising deactivating the evaporator, the first valve being fully closed, the second valve being fully open, and the third valve positioned to allow air flow from the heat exchanger to the vehicle interior while blocking air flow to the vehicle environment.
