Precise Frequency Modulation: Utilizes high-performance DC inverter motors and drives, enabling wide-band and efficient speed adjustment (typically 20–120 Hz), accurately matching system load and avoiding energy loss from frequent start-stop cycles.
High Energy Efficiency Ratio: Optimized motor design (e.g., high-flux rare-earth magnets, low iron loss silicon steel sheets) and electromagnetic solutions, combined with advanced inverter control logic, significantly improve operating efficiency (EER/COP) across all working conditions, with particularly outstanding efficiency under part-load operation.
Rapid Cooling/Heating: Quickly ramps up to high-frequency operation after startup, enabling fast room temperature reduction or increase, enhancing user experience.
High-Reliability Design and Manufacturing
Robust Structure: Features a high-strength cast iron housing and precision-machined components, ensuring long-term mechanical stability.
Superior Motor Protection: Equipped with built-in motor temperature sensors and overload protection, combined with an optimized cooling flow path design, ensuring reliable motor operation and extended lifespan even under harsh conditions (e.g., high temperatures, high loads).
Strong Resistance to Liquid Slugging: Optimized scroll profile and housing structure design enhance the ability to handle refrigerant liquid return (liquid slugging), improving system adaptability and operational safety.
Excellent NVH (Noise, Vibration, and Harshness) Performance
Low Noise Operation: Enhances gas flow paths, optimizes the compression process, and incorporates quiet bearings to effectively reduce compression noise, providing a quieter environment for users.
Smooth Speed Regulation: Inverter control ensures smooth operation and seamless speed transitions, avoiding the noise and vibration impacts associated with the start-stop cycles of fixed-speed units.
II. Environmental Compatibility and Broad Applicability
Compatibility with Eco-Friendly Refrigerants: Fully supports R32 refrigerant, which has zero ozone depletion potential (ODP=0) and a relatively low global warming potential (GWP=675). R32 is currently and will remain a mainstream environmentally friendly refrigerant, aligning with global environmental regulations. Wide Operating Range: Designed for strong adaptability, it operates stably and efficiently across a broad range of ambient and evaporation temperatures. Suitable for various climate zones, from tropical to cold regions, it meets diverse needs such as cooling and heating (heat pump applications). Excellent System Compatibility: Widely validated in the market, it demonstrates good compatibility and matching with systems from mainstream air conditioning manufacturers (e.g., heat exchangers, electronic expansion valves, control systems), facilitating easier overall unit design.
