How a Hybrid A/C Compressor Works

Here is a comparison between how hybrid car’s air conditioning compressors work compared to traditional compressors. A/C compressors use rotating energy in an orbital motion to move scroll wheels relative to each other. This motion compresses gaseous refrigerant, which is then sent to the condensor, drier and then evaporator to cool the interior. Typical internal combustion engines use the rotational energy of the engine through its accessory drive to rotate the scroll wheel. A hybrid car’s internal combustion engine isn’t always operating, especially in low speed conditions. Thus, an electric motor, driven by the same power inverter that drives the hybrid system is employed to rotate the scroll wheels. The orbital motion of the wheels can be precisely controlled according to HVAC demand, eliminating the need for a cycling clutch or a variable type compressor. The compressor opened up in this video is from a 2004 Toyota Prius hybrid. In this video, the compressor from a Chevr
