Operating characteristics of an active chilled beam terminal unit under variable air volume mode

Inappropriate understanding operating characteristics of active chilled beam systems is a critical barrier that stands in the way of the success. Taking a 2-way discharge active chilled beam terminal unit as an example, this paper reveals its operating characteristics unit under variable air volume mode. Based on an experimentally verified model, a series of realistic simulations are carried out. Besides the Total Cooling Output Capacity (TCOC), the reported performance parameters include the Sensible Heat Ratio (SHR) and the energy saving potential indexe^ε. Inherent correlations between these characters are illuminated. In addition, influences of different space conditions are studied. The results obtained here are expected to achieve a better understanding of the active chilled beam systems, so as to a better system design and operating and control strategy for improved indoor thermal environment.
