TCD08CA
The TCD08CA electric bus air conditioner is a high-voltage energy-saving HVAC solution independently developed by TCHAIN for 8-8.5 meter new energy electric buses, including pure electric urban buses, new energy shuttle buses and electric commuter buses. As a core accessory for new energy commercial vehicles, this product abandons the traditional engine-driven mode and adopts a DC420V-720V high-voltage direct current power supply, perfectly matching the high-voltage electrical system of electric buses without consuming the vehicle’s driving power. With a high cooling capacity of 26000KcaL/h, it meets the cooling demand of the 8-8.5m electric bus cabin, and features an energy-saving design and low-noise operation, effectively extending the driving range of electric buses. The TCD08CA is a customized model for the new energy bus market, with modular core components and easy integration with the electric bus’s central control system, making it an ideal choice for new energy bus manufacturers, urban public transport companies and new energy fleet operators.
Supports DC420V-720V high-voltage direct current power supply, adapting to the high-voltage electrical system of most 8-8.5m pure electric buses on the market, with no voltage matching conflict.
26000KcaL/h high cooling capacity delivers rapid and efficient cooling, meeting the cooling demand of the closed cabin of 8-8.5m electric buses under full passenger load and high-temperature environments.
Optimized high-efficiency compressor and heat exchange system, with low power consumption and no impact on the electric bus’s driving range, realizing energy-saving operation of the whole vehicle.
Integrates high-voltage compressor, evaporator expansion valve, condenser and receiver series, with a modular design that is easy to integrate with the electric bus’s central control system and realize intelligent temperature control.
Abandons the engine-driven mechanical transmission, with the high-voltage compressor running at low noise, reducing the cabin noise of electric buses and improving passenger riding comfort.
