The 2022 International Production & Processing Expo (IPPE), was held January 25-27, 2022 in Atlanta with more than 500,000 square feet of exhibit space and 1,140-plus exhibitors. Attendee numbers had not been released when this was written. Sponsored by the U.S. Poultry & Egg Association, American Feed Industry Association and the North American Meat Institute, IPPE is the world's largest annual poultry, meat and animal food industry event of its kind. 

With the approaching HFC phasedown, the demand for environmentally friendly cooling systems is driving chiller manufacturers to innovate. Washington-based Pro-Refrigeration, Inc., a leading manufacturer and supplier of chillers for the industrial and beverage processing market, including the dairy, beer and wine industries, recognized an opportunity with CO2 chillers. 

The 2022 AHR Expo co-sponsored by ASHRAE and AHRI was held Jan. 31 – Feb. 2, at the Las Vegas Convention Center. A total of 1,573 exhibitors (281 international) spread out over 440,000 square-feet, and 80 free sessions in the Education Program drew more than 30,000 attendees to the event. Common trends discussed amongst exhibitors focused on energy efficiency, operational reliability, connectivity and new chiller refrigerant transitions spurred by approaching regulatory transition dates in the AIM Act enacted by US Congress in late 2020. 

Like many universities across America, The University of Cincinnati had a major challenge having to operate aging central utility plants with older technology, reduced efficiencies and capacities, with chilled water equipment at the end of its service life. Even so, UC needed to maintain plant operations under diverse load conditions, including critical hospital utility demands that are currently expanding and in daily periods subject to energy tariff.
