TECHNICAL FEATURE
the models used. The energy equation was
converged carefully, and monitoring points
were used to ensure steady solution.
The results of the numerical model with the
k-ε model were compared to the experimental
measurements.35 The results show that there
is good agreement of vertical temperature
stratifi cations with the corresponding
values of temperature stratifi cations in the
experimental studies35 (Figure 4).
Results and Discussion
A detailed analysis on the energy consumption
comparing AHU and ACB is presented in
this section. The system capacity and power
consumption are determined. System capacity
includes the capacity of the AHU, main pump, chiller;
and primary AHU, main pump, chilled beam pump,
chiller. Likewise, the power consumption includes
the equipment involved in the system, and analysis is
performed to determine which system gives a better
