Simulation Study on Air Flow Organization of MCC Air Conditioning System
A simulation study was conducted on the temperature and velocity distribution characteristics of the air conditioning system in the motor control center(MCC)room under different air supply methods and temperatures.The results verified the superiority of the underfloor supply and return air flow organization method.To ensure stable operation of the cabinet,save cooling capacity,and have a certain temperature margin,the final selection of the supply air temperature in the MCC room is 20℃.At the same time,the indicators for evaluating the air flow organization in the MCC room were analyzed,and it was found that regardless of the ventilation efficiency or energy utilization rate,the down supply and up return method was superior to the up supply and side return method.
