A waterside economizer on an air-cooled chiller is designed to cool the chilled water loop using low ambient outdoor air temperatures, instead of running the refrigeration cycle to cool the chiller barrel. This approach is especially useful in regions with many hours of low ambient conditions and a year-round need for cooling. A great example is a data center, where cooling is required 24/7 regardless of the season. #hvaclife #hvactechnician #commercialhvac #mechanicalengineer #hvac Johnson Cont
