As the transition to electric continues, zero-emissions electric buses will be the new mode of public transportation. The switch comes with its own set of challenges, many of which can be solved with an all-electric HVAC system—including battery range and electrical load. TCCI’s electric compressors provide an all-in-one solution with a variable speed motor that adjusts output to meet demand. Here are some of the benefits:
- Improve HVAC system efficiencies and electric vehicle range by matching compressor speeds and power consumption to actual cooling demands, in comparison to energy-hungry fixed speed electric compressors.
- Provide more stable cabin and battery circuit temperatures by decreasing compressor speed rather than shutting off to avoid evaporator freeze like fixed-speed compressors.
- Improve reliability and reduce total costs by reducing the number of independent parts, by integrating the power inverter, DC-link capacitors, and EMC filters into a single leak-tight compressor housing.
