The Future of Energy: Smart Chillers - Siemens Global

According to projections, the number of air-conditioners could triple by the year 2050. That’s why optimizing the operation of chillers – which are a component of air-conditioners – plays a key role. Their optimal operation is even more important in a world that’s increasingly dependent on renewable energies.

Email. A chiller is often the single largest consumer of power in a building, so it’s a logical place to look for reduced energy costs. Chillers expend excess energy when their compressors run at full-rated constant speed, a wasteful and unnecessary operating condition. Most chillers operate at partial load or are off 99% of the time.
