Inverter Water Cooled Screw Chiller (SCWF***EV)

Description

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

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

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)
