Cooling large buildings typically requires the use of air- or water-cooled chillers that produce chilled water, which then cools the air. About 39% of buildings over 100,000 square feet use chilled-water systems employing various refrigeration compressor designs.

Snail mail. Rolodexes. Boomboxes. We’ve given up the familiarity of the past for the promise of the future. But is the same happening in the chiller industry? Is the push for lower global warming potential (GWP) refrigerants changing the industry as we know it? In some ways, yes. But, in the United States in particular, the change may be more gradual than it appears at first glance.
The craft brewing industry has exploded over the past several years. According to the Brewers Association, in 2012 there were 2,420 regional craft breweries, microbreweries and brewpubs in the U.S. By 2017 that number had nearly tripled to 6,266. The abundance of craft brewers has led to increased competition for market share among consumers, distributors and bars – leaving little to no room for error in the brewing process.
Understanding and emulating how an existing business achieved success is often one of the biggest advantages to new business start-ups. Dogfish Head Craft Brewery, one of the first large craft breweries in the United States, has become recognized as a leader in this burgeoning industry. New breweries look to Dogfish Head’s model for implementing ideas that work without experiencing the irksome (and often expensive) trial and error growing pains. 
Penn State Health Milton S. Hershey Medical Center, Hershey Pa., is all about energy and resource efficiencies, which is why it adopted a new approach to managing its chilled water operation. The approach, which revolves around a software and analytics platform used to optimize three chiller plants in addition to various equipment upgrades, has allowed it to save 4.16 GWh/yr in electrical energy consumption – and shave $300,000 off of its annual electrical costs. With an incentive from the local utility of $415,799, the multi-phased initiative achieved a payback of 4.3 years. 
Given that HVAC systems typically account for 44% of commercial buildings’ energy consumption1, HVAC optimization should be a priority efficiency upgrade after lighting improvements and other low-hanging fruit. Full-scale HVAC optimization typically reduces energy usage and costs by 20 to 40%, improves system reliability by operating equipment more efficiently and at optimal temperatures, ensures consistently healthy air quality and building comfort, and reduces a building’s carbon footprint.
The NPE 2018 International Plastics Showcase was held at the Orange County Convention Center in Orlando, Florida, May 7-11. Setting all-time records, the Show attracted 2,180 exhibitors — including Chiller & Cooling Best Practices and Compressed Air Best Practices® Magazines! Over 1,200,000 square feet of exhibition space was used, breaking the all-time NPE record. Held once every three years, NPE 2018 registered attendance was 56,000.
A common misconception in plastics injection molding is that coolant temperature is the one true path to achieve productivity and profitability. The reality, however, is that turbulent flow is the primary force behind efficient cooling and a key driver in the ability to achieve operational efficiencies, increase profits and consistently produce high quality products.
The ComEd® Energy Efficiency Program offers incentives to help facilities save money by improving the efficiency of their equipment. Industries can receive standard cash incentives for common energy efficiency improvements or custom cash incentives for making improvements not included in the standard program.
An airside economizer is typically used on a packaged rooftop or tied to an indoor AHU, allowing filtered outside air into the space when outdoor temperatures drop below 55°F (12 °C) (the common supply air temperature of indoor spaces) thus alleviating the need for the refrigeration cycle to be running. Interior space is being cooled yet the refrigeration system is not running, hence the name Free Cooling.
Commercial buildings in the United States will be looking to replace centrifugal chillers as many are near or past their median replacement life of 25 years. This becomes apparent when you consider nearly half of all commercial buildings were constructed before 1980 according to data from the U.S. Energy Information Administration. The same can be said of buildings on American college campuses, which according to the same data, more than half of which were built before 1990. Bottom line — if you’re a commercial building owner or a facility manager/director in the United States, you may need to replace a chiller.
