Description

Introduction

Midea Centrifugal Chillers are a significant investment in your building system. The full failing film heat exchange technology also be used to increase the efficiency and decrease the refrigerant charging volume up 40% less compared to the flooded type.
•R134a refrigerant
•Smallest footprint in the industry to optimize equipment room space.
•Unmatched unloading due to patent compressor design with movable diffuser geometry.
•Quiet compressor design with unique refrigerant injection system to absorb sound energy.
•Easy to retrofit with bolt-together construction for easy disassembly and re-assembly at the job site.
•Controls flexibility – Intelligent controls with our open feature allow easy integration with your BAS of choice using LonWorks, BACnet or Modbus communication.

Patent compressor design
Patent compressor design
Keyless impeller coupling with high speed shaft(PATENT NO.: ZL 01 2 56824.4)
The impeller is coupled to the shaft without any key to eliminate any excess stress to the shaft. Ensures the high speed shaft operates stably and it’s life span.
Patent compressor design2
Pre-swirling Guide Vane Technology
The compressor is equipped with airfoil shaped pre-swirling guide vane, which produces swirl under different load conditions, hence to extending the operation range and increasing the part load efficiency.
