The problem as posited is the variety of powertrains that are offered by global automakers. The problem is they all must provide what used to be known as HVAC [Heating, Ventilation and Air Conditioning for some vehicle components and its occupants. The system is apparently not in broad use in the U.S. at the moment, but the possibilities of cost-lowering mass production and part number consolidation are compelling. – AutoCrat]

“Gasoline engines, diesel engines, a variety of hybrids and fully electric vehicles are all on the road, with no clear winner. Each needs a different approach to heating and cooling, from a simple setup with a traditional engine to complex heat pumps in electric vehicles. The challenge is building one system architecture that scales across all of them without starting from scratch,” according to a social media post by German auto component supplier Bosch.
“Refrigerants are changing, too. In Europe, a proposed PFAS restriction could affect today’s widely used automotive refrigerant. Natural refrigerant alternatives could potentially be approved for certain automotive applications in the United States, but broader adoption involves additional technical and safety considerations. Automakers must navigate evolving regulatory requirements and technology choices while managing their own multi-year development cycles.

“Bosch’s answer is scalable integration. Instead of separate pumps, valves and compressors linked by hoses, clamps and wiring, the parts come together in one compact module. Fewer connections mean fewer chances for leaks, higher quality and lower cost.”
