Hitachi scroll compressors, with their innovative structural design and precision manufacturing processes, serve as efficient and stable core power sources for both commercial and residential HVAC systems. This series of compressors combines the inherent advantages of scroll technology with Hitachi's extensive expertise in electromechanical systems, delivering outstanding performance in energy efficiency, noise control, and operational reliability. They meet the diverse requirements of modern refrigeration systems for energy savings and quiet operation.
I. Core Product Features
Simplified Structure, Stable Operation The compression mechanism of the scroll compressor consists of only five core components, significantly reducing moving parts and mechanical wear. This design ensures long service life and high reliability from the outset.
Low Vibration and Low Noise Operation The fixed crankshaft structure and optimized exhaust buffer cavity design effectively suppress airflow pulsation and mechanical vibration, resulting in noise control superior to comparable products. Suitable for applications with strict quietness requirements.
Direct Suction and Efficient Compression Mechanism Suction bypasses the suction valve structure, reducing pressure loss and superheating, thereby significantly improving volumetric efficiency. The direct return gas method also avoids liquid slugging risk, protects the integrity of the lubricating oil film, and enhances overall system operational reliability.
Differential Pressure Oil Supply Lubrication System Utilizing a differential pressure-driven forced lubrication mechanism, it ensures critical moving parts such as bearings and scroll wraps remain fully lubricated, enhancing the unit's durability and adaptability to extreme operating conditions.
High-Reliability Design The scroll structure eliminates the need for suction and discharge valves, fundamentally avoiding issues like valve fatigue and debris. This ensures smooth operation, low failure rates, and suitability for frequent start-stop cycles and fluctuating load scenarios.
Wide Operating Range Maintains high efficiency even under high pressure ratios, high speeds, or low-temperature conditions. Supports flexible adjustment and stable output across various operating scenarios, demonstrating strong adaptability.
II. High-Efficiency Technology Analysis
Mechanical Efficiency Optimization Equipped with an intermediate pressure servo adaptive mechanism that dynamically balances axial gas forces and controls the sealing clearance between the scrolls, minimizing frictional losses and improving mechanical transmission efficiency.
Volumetric Efficiency Enhancement Features a built-in efficient baffle-type oil separation device and optimized internal oil passages, significantly reducing oil carryover in the discharge gas. This improves system heat exchange efficiency and reduces the impact of refrigerant migration on performance.
High-Efficiency Motor Technology Incorporates high magnetic energy product rare earth permanent magnet materials and optimized electromagnetic design. Combined with precise control of the refrigerant flow path, it enables efficient motor cooling and low-loss operation, further improving the comprehensive Coefficient of Performance (COP).
