Hitachi Compressor Features

Hitachi Compressor Features Fewer parts The compression structure of a scroll compressor consists of only five main parts. Lower vibration/noise Fixed crankshaft structure and large enough exhaust buffer structure to reduce vibration and noise Direct inhalation, low inspiratory preheating, higher volumetric efficiency Direct suction, without the damage of the liquid refrigerant to the lubricating oil film, making the compressor work more reliable and more efficient More reliable fuel supply The differential pressure oil supply makes the lubrication of the moving parts of the compressor more reliable, thereby improving the reliability of the whole machine. High reliability Since the scroll compressor does not need to be equipped with an intake valve, the operation is more stable, high efficiency and high reliability. Wide operating range Under a wide range of operating pressure ratio, high-efficiency operation can still be maintained. Scroll compressor can still get quite stable operation under high rotation speed. The high efficiency principle of Hitachi high efficiency scroll compressor Higher mechanical efficiency The automatic servo mechanism of intermediate pressure is set to ensure that the axial gas force can be reliably and effectively balanced, and at the same time, the friction loss between the movable and fixed scrolls is minimized. Higher volumetric efficiency A built-in fin baffle oil separation device is installed, and the internal oil circuit of the compressor is optimized to improve the separation effect of the exhaust gas of the compressor, reduce the oil content of the refrigerant, and improve the heat exchange effect of the system. High efficiency motor Using new methods and new materials (such as rubidium paste boron magnets) to improve the efficiency of the motor: At the same time, the refrigerant flow path of the compressor is redesigned, so that the motor can be cooled optimally, and the efficiency of the motor is further improved.
