The most recent International Institute of Ammonia Refrigeration Conference took a look of some of the latest research in terms of working with equipment running on natural refrigerants. The significance was not lost on attendees as such refrigerants continue to gain a foothold in commercial as well as the long-standing industrial applications. Last month we highlighted four of those papers. We now look at the remaining four.
One ongoing focus of research with ammonia was to find ways to reduce its charge to allow wider applications. For Pega Hrnjak, president of CTS, and resident professor and co-director, Air Conditioning and Refrigeration Center at the University of Illinois that could encompass what he called “ultra-low charge” ammonia systems.
