Abstract
A vehicle heating and cooling system comprises an evaporator, a compressor, a condenser, an auxiliary heating system, primary working fluid, and at least one valve assembly. The primary working fluid is configured to flow between the interior heat exchanger and the compressor. The at least one valve assembly configured to operate in a cooling mode in which the primary working transfers heat from the interior system to the compressor system, a standard heating mode in which in which the primary working transfers heat from the compressor system to the interior system and the auxiliary heating system does not transfer heat to the primary working fluid, and an augmented heating mode in which the auxiliary heating system transfers heat to the primary working fluid.
