VFD Direct Drive centrifugal Chiller
250 - 550 RT
VFD Direct Drive – Benefits
• Energy saving: COP 6.2 - 6.5, IPLV up to 11.5
• Lower total cost of ownership
• Lower noise
• Patented horizontal back-to-back impeller design ensures less seal leakage and
no gear loss, leading to longer lifespans and improved efficiency
• 360⁰ cooling of compressor motor
• Patented full falling film evaporating technology fully utilizes heat exchange tube
capabilities, improving efficiency
Two-stage compressor impellers
Traditional design
• Stages arranged in series in same
direction
• Higher axial forces and higher stress in
thrust bearings can lead to damage
Midea design
• Unique self-balanced structure
• Axial load on bearings 10% lower
• Lower mechanical losses
• More stable running => longer lifespans
