New Study Shows No Negative Impact to EER Using Bypass Zone Systems

The Zone Control System Technology (ZCST) Product Section of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) today released the results of a field study that evaluated the impact on the energy efficiency ratio (EER) of a bypass-type single-stage cooling zone system. The results revealed a positive influence on the system's EER, with no negative impact.
