Ammonia is known to be one of the most energy efficient refrigerants, but its use has mainly been limited to large industrial system applications. Low-charge ammonia chiller technologies recently introduced to the U.S. market have the potential to improve efficiency in many commercial refrigeration applications while addressing previously-held concerns. The presentation showcases an ammonia chiller installation in Irvine, California and share preliminary performance information compared to the existing R-507A system.
