PRODUCT FEATURES

Vi Optimizing Inverter Technology of Midea's Independently-developed Inverter Twin Screw

Midea's independently-developed volume ratio optimization control technology integrates the characteristic curves of a compressor, inverter, motor and maximizes the performance and reliability of the inverter screw compressor. The maximum isentropic efficiency is 76%, far higher than other adjustment methods.



Parallel Dual Compressor Design

The dual-compressor unit is designed with the parallel system of double compressors and the total heat exchange area is used to greatly improve the operation efficiency when the single compressor operates. (Customization of non-parallel system accepted)



No Impact of the Power Grid

This product utilizes inverter start with a smooth starting current of less than the Wye-Delta starting current, without any current impact, which prolongs the service life of motor.



Energy Saving Principle of Inverter Adjust

The inverter screw unit regulates the cooling capacity by reducing the frequency. The COP of the partial load is better than the fixed frequency unit, which greatly enhances the energy efficiency.



Accurate Control

Innovative swirl orifice plate throttling technology:

• The flow resistance increases when the gas content of refrigerant is high before the orifice plate, which greatly improves the cooling capacity attenuation caused by hot gas bypass under the partial load.
• When the condensation pressure is low and the refrigerant in front of the orifice plate is liquid, the liquid flow rate can be accelerated to increase the liquid pply.
