Abstract
A heat pump system for a vehicle comprises a heating, ventilating, and air conditioning module as well as a refrigerant circuit including a compressor, an internal condenser, and an external condenser. The module comprises a warm air path including the internal condenser, a cold air path formed independently from the warm air path, a purge flow path branching from the warm air path at a position downstream of the internal condenser with respect to a flow of air through the module, and a purge control door adjustable between a first position preventing fluid communication between the warm air path and the purge flow path and a second position allowing fluid communication between the warm air path and the purge flow path. The purge flow path provides fluid communication between the warm air path and the ambient environment.
