Newbase Unveils Breakthrough Electric Bus Air Conditioning System for Extreme High-Temperature Operations

As electric buses become increasingly deployed in high-temperature regions worldwide, the demand for reliable, high-performance air conditioning systems has never been greater. Traditional cooling solutions often struggle under extreme heat, compromising passenger comfort and vehicle efficiency. Addressing this critical challenge, NEWBASE—a leader in new energy vehicle thermal management—has developed an innovative high-temperature electric air conditioning system tailored for electric buses, setting a new industry benchmark for performance and reliability.

Unlike conventional systems relying on R134a refrigerant—which often falls short in cooling capacity and energy efficiency under high thermal loads—NEWBASE’s advanced electric bus air conditioning system delivers exceptional performance even in extreme environments. Through optimized system design and intelligent thermal management, the unit ensures consistent cooling efficiency, passenger comfort, and operational safety.

In rigorous testing conducted in late 2020, the NEWBASE High-Temperature Electric Air Conditioning Unit demonstrated outstanding results:

• Maximum cooling capacity of 29 kW
• Optimal system energy efficiency ratio (EER) of 2.42
• Stable operation in ambient temperatures up to 50°C, with reliable performance maintained even at 55°C

These results confirm the system’s ability to meet the full thermal load requirements of electric buses under the most demanding conditions.

1. Platform-Based Optimized Design: Built on NEWBASE’s mature technical platform, ensuring high compatibility, reliability, and ease of integration.
2. Integrated Thermal Management: Unifies cabin cooling and battery thermal management into a single, efficient system, reducing cost by 30% and weight by 20% compared to separate units.
3. Advanced EMC Compliance: The 3EMC technology meets GB/T-18655 Class 3 standards and holds EU certification, ensuring electromagnetic compatibility and safety.
4. High-Efficiency Permanent Magnet Synchronous Inverter Compressor: Features adaptive frequency regulation, significantly improving energy efficiency and reducing power consumption.
5. Multi-Level High-Temperature Safety Protections: Designed with high-temperature and high-pressure safeguards to ensure stable and secure operation under extreme conditions.
6. Intelligent Refrigerant Flow Control: Utilizes multi-path electronic expansion valves and P+T pressure sensors with PID control to precisely distribute cooling between cabin and battery systems, eliminating uneven cooling distribution.
