How does the heat pump work in an Audi A7?

I've heard that the Audi A7 has a heat pump but can someone explain how it works and its benefits?

The heat pump in an Audi A7 uses a small, efficient electric compressor to transfer heat from the ambient air to the refrigerant gas, which is then used to heat the cabin. This reduces the load on the engine and increases overall efficiency.

The heat pump in an Audi A7 is most effective in cold weather, where it can provide up to 50% energy savings compared to traditional heating methods. It also works in reverse for cooling in warmer weather.

The heat pump in the Audi A7 is also beneficial for sustainability, reducing CO2 emissions and contributing to a more eco-friendly drive. It's just one of the many advanced features in the car.
