Thermal system

A vehicle cabin heating loop configured to circulate a liquid coolant from a liquid coolant reservoir that is configured to receive and distribute the liquid coolant, the vehicle cabin heating loop comprising:

• a pump configured to receive the liquid coolant from the liquid coolant reservoir;
• a condenser positioned downstream of the pump;
• a radiator positioned downstream of the condenser;
• a cabin heating subsystem positioned downstream of the condenser and parallel to the radiator;
• a heating valve positioned upstream of the radiator and the cabin heating subsystem, the heating valve configured to direct at least some of the liquid coolant to the radiator and at least some of the liquid coolant to the cabin heating subsystem;
• and
• a cooling valve positioned at an outlet side of the radiator and upstream of an outlet side of the cabin heating subsystem, the cooling valve configured to direct the liquid coolant from the radiator to the liquid coolant reservoir or the condenser.

A vehicle thermal system, comprising:

• a liquid coolant reservoir that receives and distributes a liquid coolant;
• a first liquid loop that is connected to the liquid coolant reservoir and circulates a first amount of the liquid coolant to a vehicle subsystem;
• and
• a cabin heating loop that circulates a second amount of the liquid coolant to a cabin heating subsystem, wherein the cabin heating loop includes:
• a heating valve positioned upstream of a radiator and the cabin heating subsystem, the heating valve configured to direct at least some of the liquid coolant to the radiator and at least some of the liquid coolant to the cabin heating subsystem;
• and
• a heating return valve that defines a first connection between the cabin heating loop and the liquid coolant reservoir and a second connection between the cabin heating loop and the liquid coolant reservoir, wherein the first connection to the cabin heating loop is positioned upstream of the radiator and the second connection to the cabin heating loop is positioned downstream of the radiator.
