The characteristics of Hitachi scroll compressor

A, lower vibration, noise

The fixed structure and exhaust buffer structure is large enough, the vibration and noise is smaller.

Direct suction, suction preheating small, higher volumetric efficiency

There is no direct suction, destructive effect on liquid refrigerant lubrication, enhance the working reliability of the compressor, high efficiency.

Two, high reliability

Because of the scroll compressor without 2 installed suction valve sheet and exhaust valves, so, the operation is more stable, high efficiency and high reliability.

Three, wide operating range

In a wide range of operating pressure ratio, can still maintain a high efficiency operation. The scroll compressor in high rotary speed, can still be quite stable.

The principle of high efficient Hitachi scroll compressor

Mechanical efficiency, a higher

Set up the middle pressure automatic servo mechanism, ensure the axial gas force can be a reliable and effective balance, while ensuring the dynamic, friction loss between the scroll down to the lowest.

Two, high volume efficiency

Set the built-in fin oil baffle device, and an internal circuit of the compressor to optimize the design, improve the exhaust oil compressor high effect, reduce the rate of refrigerant oil, improve the effect of heat transfer system.

Three, a high efficiency motor

The use of new materials, new methods (such as neodymium iron boron magnet), to enhance the efficiency of the motor; at the same time the refrigerant flow path of the compressor is redesigned, the motor can obtain the best cooling, to further enhance the efficiency of the motor.
