Integrated Electric Bus Air Conditioning and Thermal Management System
Welcome to the future of electric bus air conditioning with our integrated thermal management system, designed specifically for electric buses. This cutting-edge solution not only enhances passenger comfort but also ensures optimal battery performance and safety.
Product Features:
1. Integrated Battery Cooling and Cabin Air Conditioning: Our innovative design integrates battery cooling with cabin air conditioning, reducing costs by 30% and weight by 20%, making it a cost-effective and efficient choice.
2. Dual Functionality in Low Temperatures: Designed to operate effectively under low temperature conditions, our system provides both cabin heating and battery cooling simultaneously, ensuring all-year-round efficiency.
3. Advanced Temperature Control: Featuring multiple electronic expansion valves and P+T pressure sensors, our system utilizes intelligent PID control technology to precisely manage compressor and condenser fan speeds as well as refrigerant flow distribution. This addresses common issues of uneven cooling between cabin and battery areas. The dual-system, dual-return air structure enables zoned temperature control within the vehicle, enhancing both passenger comfort and battery temperature regulation.
Product Advantages:
Safety:
- Low Voltage Power Protection Technology: Incorporating a DC-DC module that converts high voltage from the vehicle into safe low voltage, providing overvoltage, overcurrent, and short circuit protection to ensure reliable operation at ambient temperatures up to 65°C.
- PTC Heater Safety Protection Technology: Utilizing IGBT power modules for high voltage control with comprehensive protections against overvoltage/undervoltage, overcurrent/short circuits, and dry burnout, ensuring unparalleled safety.
- High Voltage Distribution Protection Technology: Equipped with pre-charging circuits for smooth high voltage startup and distribution to various branches, complemented by fuse protection for added security.
- 360° Shielding and Equipotential Connection Protection Technology: Safeguarding electronic components from complex electromagnetic environments in new energy vehicles, thereby enhancing reliability.
Reliability:
- Protection Rating IP67: Components including the electric compressor and waterproof connectors achieve IP67 rating, offering dustproof, waterproof, and shock-resistant capabilities, meeting automotive-grade standards.
- EMC Compliance Meeting National Standards Level I: Our system's EMC performance meets international levels, verified by third-party testing to prevent electromagnetic interference, providing a safer driving environment for drivers and passengers.
Lightweight Design:
- Full DC Inverter Technology: Reducing the weight of the compressor from 44kg (plus 15kg for the inverter) down to just 15kg, our entire unit is approximately 30% lighter than competitors.
- Use of Lightweight SMC/LFT-D Materials: Our application of advanced lightweight materials makes our product 20% lighter compared to similar offerings on the market.
- Localized Frame Treatment for Condensers: Further contributing to weight reduction, our approach results in condenser assemblies that are 10-20% lighter than comparable products.
