Vehicle HVAC system with auxiliary coolant loop for heating and cooling vehicle interior

A vehicle, comprising:

• a heating, ventilation and air conditioning (HVAC) system for heating and cooling a passenger compartment, said HVAC system including a refrigerant loop and a coolant loop;
• and
• an auxiliary coolant loop for heating and cooling at least a portion of said passenger compartment, said auxiliary coolant loop including a pump for moving a coolant, within said auxiliary coolant loop, through a first heat exchanger coupled to said refrigerant loop, a second heat exchanger positioned within said passenger compartment, and a third heat exchanger coupled to said coolant loop;
• a flow control valve for controlling a flow of coolant to said third heat exchanger;
• and
• an expansion device for controlling a flow of refrigerant to said first heat exchanger,
• wherein a temperature of said coolant within said auxiliary coolant loop is controlled utilizing said flow control valve and said pump;
• and
• wherein said first heat exchanger and said third heat exchanger are connected in parallel, said auxiliary coolant loop includes a two way flow control valve for controlling movement of coolant to said first heat exchanger and said third heat exchanger, and said pump is connected between said second heat exchanger and said two way flow control valve.
