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

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. Monthly typical load in comfort application Selection conditions

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
