Hvac Chiller Industry Statistics

Chiller demand is forecast to keep rising with a 7.4% CAGR for the HVAC chiller market through 2032 and a 9.1% CAGR for water cooled chillers through 2030, but the bigger leverage point is right in operations where better HVAC O and M can deliver 50% of building energy savings. Track how efficiency, refrigerant phase down pressures, and smarter plant control can shift chiller performance by single digit temperature and part load changes into meaningful kW and COP outcomes.
