Chillers Past, Present and Future

A couple of industry pros weigh in on how past ‘best practices’ sometimes get in the way of current potential, and on where technology might point.
April 26, 2013
We had an idea to try something different this month — invite chiller manufacturers to give us their insights on one of two topics. We invited them to either talk about common errors in project design/installation/O&M, with an eye toward helping readers get the intended performance out of their equipment. Or, they could write about what they see happening in this sector in the future. In a stroke of good luck, we had one response to each question. – Ed.)

January 2, 2013

While active beams are making great strides toward becoming a standard part of the designer’s toolbox, knowing when to deploy them is a critical judgment. The author focuses his considerable experience with them into a good look at related thermal comfort considerations. Operation and controls, two- and four-pipe systems, and condensation control strategies round out a worthwhile look at how active beams can work for you.
