Features
01
Modular Platform Design
SZR/SZQ series share a common platform with identical evaporator modules and uniform condenser dimensions, enabling complete interchangeability of HVAC units within the same vehicle model.
02
Aerodynamic Fan Cowl Design
Condenser fan cowl uses Archimedean spiral geometry and conical surface design to generate columnar airflow, eliminating hot air recirculation and improving system COP (Coefficient of Performance).
03
Premium Material Construction
Top cover molded with SMC (Sheet Molding Compound) for smooth finish and aesthetic appeal.Evaporator features eco-friendly LFT (Long Fiber Thermoplastic) molded bottom shell, ensuring monolithic structure, consistent quality, and full recyclability.
04
Ultra-Thin & Lightweight Architecture
Central profile thickness of 188mm with inverted V-shaped condenser base and bottomless structure, combined with molded composite shell for optimized weight reduction.
05
Serviceability Optimization
Hinged top cover allows partial access during installation, eliminating full removal and reducing setup time.Condenser fans install from top-to-bottom for tool-free replacement; evaporator fan maintenance requires only partial side cover removal.
06
SZR Series Technical Advantage
SZR models feature tube-fin condensers with low sensitivity to refrigerant charge variations, delivering stable performance and exceptional high-temperature reliability .
