New Energy Power truck parts Vortex type automotive air conditioning motor compressor CR36N6-2012

Adopting advanced twin-vortex compression structure, this compressor delivers exceptional cooling efficiency that outperforms traditional piston-type alternatives by 35%. The interlocking fixed and orbiting scrolls create continuous compression chambers, minimizing refrigerant leakage and achieving a volumetric efficiency of ≥95%. With a displacement of 36cc/rev, it provides a maximum cooling capacity of 6.2kW at 6000rpm, rapidly reducing cabin temperature from 45℃ to 25℃ in 8 minutes—critical for NEV summer use. The low compression ratio (2.8:1) ensures smooth refrigerant circulation, while the integrated muffler design reduces compression noise to ≤52dB(A), creating a quieter cabin environment compared to piston compressors (typically 65dB(A))

Optimized for NEV energy economy, the compressor features a variable-speed permanent magnet synchronous motor (PMSM) with an efficiency rating of ≥92% (IE4 premium efficiency class). Its 500rpm-6000rpm stepless speed regulation adapts cooling output to real-time cabin demands—reducing power consumption by 40% during mild cooling compared to fixed-speed compressors. The built-in temperature sensor and electronic expansion valve (EEV) work in tandem to maintain cabin temperature within ±0.5℃, avoiding frequent on-off cycles that waste battery power. In practical tests, it reduces air conditioning-related energy consumption by 15-20%, extending NEV driving range by 30-50km per full charge under urban conditions

Engineered for long-term reliability in NEV service, the compressor integrates a series of durability-enhancing designs. The scroll components are made of wear-resistant nodular cast iron (QT600-3) with a hard chrome coating, ensuring a service life of ≥150,000km (3 times that of aluminum scrolls). The motor is protected by a class IP67 waterproof and dustproof housing, suitable for harsh environments like rainy days or dusty roads. The refrigerant seal uses high-temperature resistant Viton O-rings (resistant to -20℃ to 180℃), preventing leakage of R1234yf or R410A refrigerants. It passes 500,000 vibration cycles (5-2000Hz, ISO 16750-3) and 10,000 thermal cycles (-30℃ to 80℃), ensuring stable operation in extreme climates

Designed for efficient NEV maintenance, the compressor features a user-friendly installation and service design. The standard SAE J639 refrigerant ports (12mm suction, 8mm discharge) and quick-connect fittings simplify refrigerant charging and replacement. The 3-point mounting bracket uses M10×30 high-strength bolts (grade 10.9) that match original NEV mounting holes, requiring only a torque wrench (45-50N·m) for installation—no specialized tools needed. The built-in self-diagnostic function (via CAN bus) reports faults (e.g., overcurrent, low refrigerant) to the vehicle’s instrument panel, reducing troubleshooting time by 60%. A 2-year/60,000km warranty and maintenance-free bearing design further lower long-term service costs for NEV fleet operators and individual users
