4. Building energy consumption
Energy breakdown
HVAC systems frequently represent a large part of a building energy consumption.
Chiller itself has a significant impact on the utility bill (~20%).
Typical building consumption breakdown
Chiller plant consumption breakdown

5. Building energy consumption
Chiller operation
Chillers are selected at most unfavorable conditions.
99% of the time, chillers operate at part load.
 Improving part load efficiency is key to reduce building energy consumption.

Chiller solution to improve part load efficiency
For decades Trane has used slide valve capacity control to:
Adapt chiller capacity to building needs
Reduce power input at part load
 Technology providing best in class efficiency
New solution: Adaptive Frequency Drive
Reduce compressor speed
Adjust compressor speed to building needs
 Keep unmatch full load efficiency and reach best in class part load efficiency
