Precision temperature control requirements: The testing of new energy vehicle battery packs necessitates precise control across a wide temperature range from -40°C to +60°C.
Continuous and stable operation: The testing center operates continuously in 24 hours, requiring equipment with exceptional reliability.
Multi-condition adaptability: Supports a wide range of testing scenarios, including motor test benches, battery environmental chambers, and charging pile testing.
Energy saving & environmental protection: In response to the national dual-carbon policy, the equipment is required to deliver a high energy efficiency ratio and utilize eco-friendly refrigerants.
Our company has tailored 6 constant-temperature and constant-flow series chillers for this project, with the following specific configurations:
Device Configuration
High-Precision Temperature Control Unit
Temperature control accuracy: ±0.05°C
Cooling capacity: 40kW/unit
Equipped with variable-frequency compressors and electronic expansion valves to achieve stepless capacity modulation
Dedicated Ultra-Low Temperature Testing Unit
Minimum water outlet temperature: -45°C
The dual-stage compression design meets the requirements of extreme testing environments
System Features
Intelligent group control system: 6 chillers operate in a networked cluster, automatically regulating the number of active units and power output based on real-time load demand.
Remote monitoring: 7-inch touch screen, LCD display, remote programmable temperature and flow control
High-efficiency heat exchange design: Incorporates shell-and-tube evaporators and flooded condensers, boosting heat exchange efficiency by 25%.
Eco-friendly refrigerant: Uses 100% R410A environmentally friendly refrigerant throughout.
Technical Performance
Compliance with precision standards: Since being put into service in June 2024, the system has consistently maintained temperature control precision within ±0.05°C for 12 consecutive months.
Excellent stability:
Over 8,000 cumulative operating hoursNo test interruptions due to equipment failure
Multi-scenario coverage:
Supports battery pack cycle life testing (simulated in a high-temperature environment at 45°C)Supports BMS low temperature protection testing (simulated in an environment at -40°C)
Supports continuous high-load heat dissipation testing for motors
Economic Benefits
Significant energy saving:
The variable-frequency system saves over 30% energy compared to the traditional fixed-frequency systemThe intelligent group control system eliminates energy waste under partial-load conditions
Low maintenance cost:
Modular design reduces maintenance time by 40%The remote early warning system avoids downtime losses caused by three potential failures
Environmental Benefits
“These six chillers have become a crucial piece of infrastructure in our testing center, providing reliable support for the R&D verification of new energy vehicles with excellent stability and precise temperature control. Especially during the hot summer, they maintain excellent performance even after operating at full load for several consecutive days, far exceeding our expectations.”
