Heat pump system for vehicle and control method thereof

This invention describes a vehicle air conditioning system that uses a heat pump to both cool and warm the cabin. It circulates refrigerant through various components like a compressor, condensers, and an evaporator, allowing it to operate in different modes for cooling, heating, or dehumidifying. The system specifically places an exterior condenser in the engine compartment, equipped with a cooling fan.

Why it matters: Filed before the widespread adoption of electric vehicles, this heat pump system's efficiency for cabin heating and cooling is now critical for EV range. Advances in vehicle electronics and thermal management systems since 2011 make the complex control of its multiple modes and refrigerant bypasses more practical.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedRefrigerant system, custom HVAC integration, electronic controls
