Reliable, Optimized Compressor Efficiency for Energy Savings Conventional chillers use inlet vanes to provide stable operation at part-load conditions. Capacity is reduced by closing the vanes while maintaining a constant motor speed. The drive can be used to significantly reduce power consumption by reducing motor speed at low load conditions. Trane patented AFD Adaptive Control™ logic safely allows inlet guide vane and speed control combinations that optimize part- load performance.

To Avoid Mechanical Stress Controlled “soft” start with linear acceleration results in limited starting current to eliminate motor stress, reduce power line disturbance and provide a lower power demand on start. Reduced motor speed as a result of reduced chiller load means less current drawn, less heat generated, increased motor winding life. This translates into longer time between compressor maintenance and less downtime throughout the life of the machine.

Application

Certain system characteristics favor installation of an AFD because of energy cost savings and shorter payback. Among them are:

A large number of part-load operating hours annually

Figure O-4, based on a CVHE500, 500-ton load at standard ARI conditions, shows that major kW savings occur at part-load conditions, typically below 90 percent load.
