1. A heating, ventilating, and air conditioning system for a vehicle, the system comprising:

  • a first circuit configured to circulate a first medium therein, the first circuit in thermal communication with an internal combustion engine of the vehicle;

    a second circuit configured to circulate the first medium therein, the second circuit in thermal communication with a heat generating system of the vehicle, the heat generating system separate from the internal combustion engine;

    a heat sink separate from the heat generating system, the heat sink in thermal communication with the first medium;

    a thermoelectric module separate from the heat generating system, the thermoelectric module comprising a first heat transfer surface and a second heat transfer surface, the first heat transfer surface in thermal communication with at least one of the first circuit or the second circuit, the second heat transfer surface adapted to be in thermal communication with an air flow; and

    a first heat exchanger disposed in the air flow and in thermal communication with the first circuit,wherein the first circuit, the second circuit, the thermoelectric module, and the first heat exchanger are configured to heat, cool, or demist the air flow, andwherein the heat generating system comprises at least one of a battery, an electronic device, an exhaust of the vehicle, a heat storage system comprising a phase change material, or a positive temperature coefficient device.
